Efficacy of Oral Probiotics as an Adjunct to Scaling and Root Planing in Nonsurgical Treatment Outcome of Generalized Chronic Periodontitis Patients: A Clinico-Microbiological Study

[Year:2017] [Month:January-June] [Volumn:6 ] [Number:1] [Pages:53] [Pages No:6-13][No of Hits : 1244]


ABSTRACT

Aim: This study aims to find out the effects of Probiotics, delivered with a lozenge for its effect on clinical and microbiological parameters in subjects with chronic periodontitis after scaling and root planing (SRP).

Materials and methods: A total of 40 generalized mild to moderate chronic periodontitis subjects were finally enrolled in a double-blind, placebo-controlled, randomized clinical study. Selected subjects after SRP were randomly divided into two groups: Group I (test group) with 20 subjects receiving probiotic tablet once daily and group II (control group) receiving placebo tablets once daily. Clinical parameters and bacterial count for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum were evaluated at baseline, 2, and 4 months after the medication.

Results: On comparative evaluation between the two groups, results indicated that group I (probiotic group) exhibited statistically significant reduction in both clinical and microbiological levels than group II (control group) over the entire span of the study.

Conclusion: Our results proved that daily oral supplementation of probiotics could be a useful adjunct to SRP in chronic periodontitis patients.

Keywords: Hyperbiotics, Periodontitis, Probiotics.

The Effect of Periogen Solution on Dental Calculus in vitro: A Pilot Study

[Year:2017] [Month:January-June] [Volumn:6 ] [Number:1] [Pages:53] [Pages No:33-34][No of Hits : 725]


ABSTRACT

Introduction: Calculus can accommodate teeth and prosthetic restorations when the patient’s oral hygiene is poor. Hardened calculus cannot be removed by patients, it needs professional cleaning using ultrasonic scaler or hand instrument. Solutions dissolving and preventing accumulation of dental calculus may help to keep dentures clean. The aim of this investigation was to examine the effect of Periogen on dental calculus in vitro.

Materials and methods: Calculus was collected via scaling from patients during a routine dental checkup. The samples were stored in carbamide peroxide solution (5%) for 24 hours, then rinsed and stored in distilled water. First, the Ca2+ content of the calculus was determined by photometric method after treating with cc. hydrochloric acid solution for 1 hour. The calculus samples were put in Periogen solution, prepared according to manufacturer’s instruction for 16 hours, then crushed and put in Periogen solution with the same concentrate for 4.5 hours. The Ca2+ dissolved from calculus was measured using same photometric method.

Results: Calculus samples contained 26 mg/100 mg Ca2+, which is similar to dentin (27-28 mg/100 mg) and to enamel (36 mg/100 mg). The Ca2+ dissolved from calculus after treating with cc. hydrochloric acid for 1 hour was considered 100%. Ca2+ dissolution was 1.5% after 16 hours (0.09%/h) and 5.45% (1.21%/h) for the next 4.5 hours after pulverizing the sample. This showed Periogen Ca2+ dissolution was 385 &3x03BC;g/100 mg after 16 hours direct contact with the material.

Conclusion: The experiment showed that pulverizing the previously hard calculus was done easily after soaking it in Periogen. The ability of Periogen to soften the calculus needs to be further investigated.

Keywords: Calculus, Oral disease, Periodontal, Periogen.

Thalassemia Major and related Dentomaxillofacial Complications: Clinical and Radiographic Overview with Reference to Dental Care

[Year:2017] [Month:July-December] [Volumn:6 ] [Number:2] [Pages:55] [Pages No:95-104][No of Hits : 674]


ABSTRACT

Introduction: Thalassemia is one of the most common genetic disorders worldwide and presents public health and social challenges in areas of high incidence. Thalassemia major (TM) type is associated with most severe clinical changes.

Aim: To evaluate dental and oromaxillofacial features of TM.

Materials and methods: The sample consisted of 54 children and adolescents with TM, 31 males and 23 females, aged 5.5 to 18.3 years (mean age 11.6 ± 3.2 years) and thalassemia-free controls. They were examined for dental caries, oral hygiene, periodontal status, orofacial features, tooth size and dental arch dimensions, dental development, and physical pattern. Clinical, radiographical, and odontometric assessments were carried out.

Results: Thalassemia major patients were at high risk of dental caries. The average decayed, missing, filled tooth (DMFT) value was 6.26 for 15-year-olds compared with 4.84 in the control group (p < 0.001). Poor oral hygiene and gingivitis were observed in 61.1 and 92.2% of the thalassemic patients respectively. Clinical orofacial features of TM include frontal bossing, saddle nose, and maxillary protrusion, giving a “chipmunk”-like face. Lip incompetence, dental discoloration, and pallor oral mucosa have been noted. Radiographical examination showed the following: thickened frontal bone, thinned mandibular cortex, and maxillary sinus hypoplasia. Class II malocclusion, significant reduction in tooth size and dental arch dimensions, and delay in dental development were evident. Growth retardation was present in 75.9% of the patients.

Conclusion: Thalassemia major produces a variety of orofacial and systemic complications that increase with age. Early diagnosis and management allow more favorable prognosis and minimize complication.

Clinical significance: Dental practitioners, especially working in multiracial communities, require understanding of the complications and management of the disease.

Keywords: Dental care, Dental development, Orofacial features, Physical growth, Thalassemia major.

A Modified Three-piece Base Arch for en masse Retraction and Intrusion in a Class II Division 1 Subdivision Case

[Year:2017] [Month:January-June] [Volumn:6 ] [Number:1] [Pages:53] [Pages No:26-32][No of Hits : 663]


ABSTRACT

This case report describes the orthodontic and orthopedic treatment of an 18-year-old male patient who presented with prognathic maxilla, deep bite, low mandibular plane angle, and proclined incisors. Modified three-piece base arch was used for the intrusion and retraction of maxillary incisor. En masse retraction was achieved in 6 months. Reduced time for retraction was attributed to a single stage of retraction unlike Burstone three-piece intrusion base arch where canines are individually retracted followed by retraction of incisors. A modified utility arch was used in lower arch followed by a continuous archwire technique. The case was finished using bite settling elastics on a continuous archwire. The step between canine and premolar was corrected in the finishing phase of treatment. The final treatment outcomes were satisfactory and true intrusion was achieved with proper selection of biomechanics.

Keywords: Biomechanics, Intrusion, Segmental mechanics, Three-piece base arch.

Depth-of-cure of Bulk-fill Composites Cured in Tooth or Opaque Substrate

[Year:2017] [Month:July-December] [Volumn:6 ] [Number:2] [Pages:55] [Pages No:68-73][No of Hits : 623]


ABSTRACT

Purpose: To determine the effect of substrate on the depth-ofcure determination when using hardness profiles in a coveredslot technique and to introduce a new covered-slot method that uses tooth substrates.

Materials and methods: Three bulk-fill composites and one conventional composite were tested: Tetric EvoCeram Bulk Fill, Venus Bulk Fill, Filtek Bulk Fill Flowable, Filtek Supreme Ultra. The composites were light-cured in rectangular slots (2 mm deep, 2 mm wide) made in a plaster mold or an extracted tooth. The slots were covered with an orange glass plate during curing, leaving one end exposed for light-curing. After curing, the glass plate was removed and the sample was stored in the dark for 24 hours before Vickers hardness was measured as a function of depth at 0.5-mm intervals. Results were analyzed using twoway analysis of variance (ANOVA) and pairwise comparisons (significance level 0.05).

Results: The hardness of composites cured in covered-slot molds decreased with increasing depth (p < 0.001). Bulk-filled composites cured in plaster molds had a slightly lower depthof- cure than those cured in natural tooth substrates. Differences between the tooth and plaster substrates were significant at all depths in the “packable” bulk-fill composite (Tetric EvoCeram Bulk Fill), and were significant at ≥2.5 and ≥3.5 mm in the flowable bulk-fill composites (Filtek Bulk Fill Flowable and Venus Bulk Fill) respectively.

Conclusion: Using natural tooth substrates in the covered-slot method increased the depth-of-cure of bulk-filled composites in comparison to opaque plaster molds.

Keywords: Bulk-fill, Composite, Depth-of-cure, Hardness, Tooth.

Dentin Dysplasia Type I: Report of Two Cases

[Year:2017] [Month:January-June] [Volumn:6 ] [Number:1] [Pages:53] [Pages No:44-47][No of Hits : 584]


ABSTRACT

Objectives: In this article, we report two cases of type I dentin dysplasia (DD): the first case is subtype “d” DD and second case is severe form of DD type I, which presents all of four subtypes and describes characteristics and the management of this type of teeth anomalies.

Materials and methods: Dentin dysplasia is a rare abnormality of dentin that involves both primary and permanent dentition. The normal shape of crown, short roots or its total absence, pulp chamber obliteration, crescent-shaped pulp, pulp stone, and periapical radiolucencies are the characteristics of DD type I.

Conclusion: There are many problems in the management of a patient with DD. Depending on root development and pulp canal situation, endodontic treatment and tooth extraction are applied in teeth with pulp necrosis and periapical abscess. The prognosis of DD largely depends upon the age at which the diagnosis is made, and the quality of the treatment provided.

Keywords: Dentin dysplasia, Pulp obliteration, Rootless teeth.

Comparison of Effectiveness of Two Designs of Interdental Toothbrushes in removing Dental Plaque

[Year:2017] [Month:January-June] [Volumn:6 ] [Number:1] [Pages:53] [Pages No:17-21][No of Hits : 583]


ABSTRACT

Aim: To compare the plaque removal ability of two designs of interdental toothbrushes (IDTBs) [“tube-like” IDTB = TT and “conical” IDTB = CT] in the posterior part of the mouth in adult patients.

Materials and methods: The study sample consisted of 107 adult patients who were in the periodontal maintenance phase having completed treatment for “chronic mild-moderate gingivitis.” Each selected patient was subjected to plaque scoring in the posterior sextants. Four sites per tooth were scored after plaque disclosing. The percentage of plaque was calculated. One of the two designs of IDTBs (TT or CT) was randomly assigned for each patient. They were instructed to carry out eight strokes back-and-forth in the relevant interdental spaces, following demonstration of the technique on a model. The interdental surfaces were reexamined for remaining plaque, and the plaque score was taken. The percentage of reduction of plaque after using the IDTB was calculated.

Results: The mean interdental plaque score for the “TT design” group (n = 56) was 82% initially, whereas the same for “CT design” group (n = 51) was 78%, and this difference was not significant statistically. Following use of TT design, the plaque score in this group was reduced to 24%, which is a 71% reduction from the initial plaque score. This reduction was significant statistically (p < 0.004; t-test). The CT design also showed a dramatic reduction (79%) in plaque score following use of this design (p < 0.007; t-test).

Conclusion: Although both designs (CT and TT) were highly effective in posterior interdental spaces, the CT design appeared to be better than TT design in controlling interdental plaque.

Evaluation of Patient Satisfaction in Implant-supported Dentures retained with Ball and Bar Attachment through Verbal Rating System

[Year:2017] [Month:January-June] [Volumn:6 ] [Number:1] [Pages:53] [Pages No:1-5][No of Hits : 561]


ABSTRACT

Teeth loss is a traumatic experience. It disturbs the total integrity of the masticatory system. Its successful rehabilitation should address a range of biomechanical problems, tolerances, and perceptions. Implant-supported overdenture with two implants placed in the interforamina region is a predictable treatment option in edentulous mandible rather than conventional complete denture as it offers increased stability, comfort, and patient compliance. Success in complete dentures is still an unanswered question as various authors have differing opinion. Patients and prosthodontists often disagree on a successful denture experience. Criteria for quality standards in denture fabrication have been articulated; however patients and prosthodontists often disagree on a successful denture experience. This study was carried out to determine patient satisfaction with implant-supported overdentures and its impact on the treatment outcome. Thirty edentulous patients were randomly divided into two groups to receive implant-supported overdentures supported with two implants in the interforamina region of mandibular arch retained with either ball or ball attachment. Questionnaires were given to the patient before and after treatment at 3- and 6-month interval. Data collected were statistically analyzed. Results obtained from this study show that patients with implant-supported overdentures were more satisfied with the treatment outcome, and there was no significant difference in patient satisfaction between the two groups.

A Rare Case of Radicular Dens in Dente diagnosed by Clinical, Radiographic, Tomographic, and Histopathological Examinations

[Year:2017] [Month:January-June] [Volumn:6 ] [Number:1] [Pages:53] [Pages No:39-43][No of Hits : 511]


ABSTRACT

Dens invaginatus is a dental anomaly caused by an invagination of enamel that affects in most of the cases the crown of the tooth. The treatment depends on the degree of invagination and morphological involvement. This report describes a dental anomaly affecting the permanent lower lateral incisor of a 13-yearold patient, which resulted in swelling, pain, and dental impaction. The initial radiographic examination suggested a gemination, a fusion with a supernumerary tooth or a dens invaginatus extending to the root. For more accurate diagnosis and treatment plan of this anomaly, computed tomography scan was performed, which revealed the presence of enamel in the root. Due to pain and the impossibility of performing an orthodontic traction, the treatment of choice in this case was dental extraction. The final diagnosis was confirmed by histopathological examination and revealed the rare occurrence of a radicular dens invaginatus.

Keywords: Cone beam computed tomography, Dens in dente, Tooth abnormalities.

Management of Tooth Wear: An Interdisciplinary Approach

[Year:2016] [Month:July-December] [Volumn:5 ] [Number:2] [Pages:68] [Pages No:139-145][No of Hits : 1668]


ABSTRACT

Aims: This case report aims to describe a conservative interdisciplinary approach to restore generalized tooth wear complicated with malalignment of teeth.

Introduction: Tooth wear is the surface loss of dental hard tissue, i.e., usually multifactorial in origin, excluding other than caries, trauma, or developmental disorder. Severe tooth wear impact the appearance, comfort, function, or longevity of the tooth. Prosthodontic management of patients with tooth wear has been well documented, although prosthodontic treatment is designed to correct minor malocclusion, patients with moderate-to-severe malocclusion accompanied by generalized tooth wear may require preprosthetic orthodontic intervention.

Case report: This case report describes a 47-year-old male patient with generalized tooth wear complicated with lack of interocclusal space and malalignment of teeth. Preventive measures were carried out to address the etiological factors of tooth wear. After orthodontic treatment, definitive restoration was placed in reorganized occlusion at an increased vertical dimension, which restored esthetic and function.

Conclusion: In this clinical report, generalized tooth wear with insufficient space for restoration, complicated by malalignment of teeth, was managed by way of an interdisciplinary approach which allowed a conservative full-mouth rehabilitation. After orthodontic treatment, a reorganized restorative approach was undertaken at an increased vertical dimension, providing an esthetic and functional solution. An occlusal night guard was provided to protect the dental restorations.

Clinical significance: Interdisciplinary approach allows a conservative management for patient with tooth wear complicated by malalignment of teeth.

Prevalence of Dental Caries, Periodontal Diseases, and Periapical Pathoses among Patients attending a Tertiary Dental Care Center in Central Gujarat: A Hospital-based Cross-sectional Study

[Year:2016] [Month:July-December] [Volumn:5 ] [Number:2] [Pages:68] [Pages No:89-92][No of Hits : 1500]


ABSTRACT

Introduction: Dental caries and periodontal disease are the two globally leading oral infections. There is considerable variation in the prevalence of these diseases. Also, these may lead to various periapical pathoses like periapical abscess, cysts, and so on. These may be attributed to differences in age, gender, sample size, geographical distribution, and protocol followed for diagnosis.

Objectives: To estimate the prevalence of dental caries, gingivitis/periodontitis, and periapical pathoses in patients of all ages in a dental institute in central Gujarat.

Materials and methods: After obtaining approval from the Institutional Ethics Committee, a hospital-based cross-sectional study was carried out in a dental institute of central Gujarat. A total of 4,642 patients were screened, out of which 2,849 subjects were included in the present study. Intraoral examination was done under all aseptic conditions by using a diagnostic set of instruments by trained professionals and the status of the pathology recorded according to the standard procedure. Data were stored in an Excel spreadsheet for analysis.

Results: It was observed that dental caries/pulp pathoses were more prevalent in the younger age group with mean age 23.1 years. All the other pathoses were observed among the middle age group (above 35 years). Overall prevalence of dental caries/pulp pathoses, gingivitis/periodontitis, and periapical pathoses was observed in 54.8% of males as compared to 45.2% females.

Conclusion: The current study collected significant data for the prevalence of three different odontogenic oral lesions in the central Gujarat geographical location at a tertiary level. There is male preponderance in the prevalence of these diseases in general. There is a need to generate awareness about oral health and the prevention of dental caries and gingivitis/ periodontitis and to institute measures for the provision of dental care services at the primary level.

Keywords: Periapical pathoses, Periodontitis, Pulp pathoses.

Prevalence of Gingival Recession and associated Risk Factors among 18–45-Year-Old Who Attended a Dental Practice in Greece

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:28-33][No of Hits : 1416]


ABSTRACT

Aim: To assess the prevalence of gingival recession and to investigate possible associations among gingival recession and periodontal and epidemiological variables in a sample of Greek adults in a general dental practice.

Materials and methods: A sample of 640 Greek adults was examined clinically and interviewed regarding several periodontal and epidemiological variables. Collected data included demographic background (age, gender, level of education), oral hygiene habits, and smoking status. Clinical examination included the recording of dental plaque and supragingival calculus presence, gingival status, and gingival recession. In addition, the association between gingival recession and the following variables was assessed: gender, smoking status, calculus presence, plaque control methods, plaque index, gingival index, and level of education. Multiple linear regression analysis was carried out to model the association of gingival recession with the mentioned potential risk factors.

Results: The overall prevalence of gingival recession was 62.7%. The performance of multiple linear regression analysis indicated that smoking (p = 0.001), plaque index (p = 0.021), gingival index (p < 0.0001), plaque control methods (p < 0.001), and level of education (p < 0.001) were the most important associated factors of gingival recession.

Conclusion: The present study indicates that an association exists between gingival recession and presence of gingival inflammation, inadequate oral hygiene habits, and smoking.

Platelet-rich Fibrin Influences on Proliferation and Migration of Human Gingival Fibroblasts

[Year:2016] [Month:July-December] [Volumn:5 ] [Number:2] [Pages:68] [Pages No:83-88][No of Hits : 1153]


ABSTRACT

Aims: Our study focused on the fabrication of platelet-rich fibrin (PRF) and evaluated its influences on cell behaviors, including proliferation and migration.

Materials and methods: Platelet-rich fibrin was prepared from human peripheral blood according to Choukroun’s method without using nonanticoagulant and foreign factors for platelet activation. Platelet-rich fibrin architecture was studied by hematoxylin and eosin staining. The investigation of PRF effects on human gingival fibroblasts (hGFs) was conducted via PRF liquid extract. Cell proliferation was determined via the number of cells after a period of time incubated in PRF liquid extract. Influence of PRF liquid extract on the migration of hGFs was conducted via scratch wound healing assay.

Results: Histological staining reviewed the natural fibrin fiber matrix of PRF. Platelet-rich fibrin liquid extract promoted hGF proliferation after 7 days of cultivation. Human gingival fibroblast proliferation in PRF liquid extract was more superior than those cultured in complete medium. Platelet-rich fibrin was also found to be able to promote the migration of hGFs for up to 48 hours.

Conclusion: These results indicated that PRF is suitable to be used as autologous natural biomaterial in supporting wound healing and in further application in periodontitis treatments.

Efficacy of “Oil Pulling” on Gingival Health and Biofilm Accumulation in a Group of Young Adults: A Pilot Study

[Year:2016] [Month:July-December] [Volumn:5 ] [Number:2] [Pages:68] [Pages No:113-117][No of Hits : 835]


ABSTRACT

Aims: The aim of this pilot study was to assess changes in gingival bleeding and biofilm accumulation in young adults undergoing oil-pulling treatment together with standardized oral hygiene practices, compared to a control group of patients that did not undergo oil pulling but maintained the standard oral hygiene practices outlined in the study.

Materials and methods: The experiment was designed as a randomized, two-way, single-blind, crossover with a 2-month washout period between two, 10-day experimental periods. A total of 28, randomly selected dental students who met the inclusion criteria were assessed for gingival bleeding and biofilm on six teeth before and after rinsing with sesame oil for 10 minutes per day, for a period of 10 days. The mean difference between the test and control group’s reduction in scores was analyzed using the paired t-test. The level of significance was set at α (alpha) = 0.05.

Results: There were no statistically significant differences on plaque biofilm accumulation and bleeding when compared with the control group. There was a higher reduction in gingival bleeding scores (albeit not statistically significant) among those who used sesame oil compared to those who did not.

Conclusion: Based on the current study, it appears that oil pulling for 10 minutes and for a period of 10 days using sesame oil has no significant benefit over brushing and flossing alone, on a sample of 28 dental students.

Keywords: Biofilm, Experimental dental science, Gingivitis, Oil pulling, Sesame oil.

ABSTRACT

Restoration of grossly mutilated primary maxillary incisors affected by early childhood caries has been a challenging task for the pediatric dentist due to the little amount of tooth structure available for bonding and behavioral problems of the children. A variety of treatment options ranging from extraction followed by prosthesis to the usage of intracanal pins and fiber posts have been reported in the past. The present case report depicts one such a case wherein biological restorations were used as post and core to restore the mutilated primary maxillary incisors in a 4-year-old child treated under general anesthesia.

Influence of QMix Irrigant on the Accuracy of Four Different Electronic Apex Locators

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:23-27][No of Hits : 786]


ABSTRACT

The aim of this study was to compare the accuracy of four different electronic apex locators in the presence of various irrigation solutions or dry canal condition. Nineteen mandibular incisor teeth were selected. The real working lengths (RWL) of teeth were measured with #15 K-file. The electronic working lengths (EWLs) were measured with Root ZX mini, Raypex 6, iPex II, and Propex II under the condition of dry canal and in the presence of sodium hypochlorite and QMix. The difference between EWL and RWL was calculated. Root ZX mini was more accurate than Propex II under dry condition. No difference was found between the electronic apex locators in the presence of sodium hypochlorite (NaOCl). In the presence of QMix, Propex II and Root ZX mini demonstrated more accurate measurements than iPex II. Root ZX mini was found more accurate under dry condition than in the presence of QMix. Raypex 6 demonstrated more accuracy in the presence of QMix when compared with NaOCl. iPex II showed similar measurements with all tested solutions. Propex II was more accurate in the presence of QMix. All devices can be considered reliable when used with QMix irrigation solution and with any irrigant.

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:34-39][No of Hits : 775]


ABSTRACT

The objective of our study was to compare the clinical and anesthetic efficacy of 4% articaine, 0.5% bupivacaine, and 2% lignocaine in maxillary extractions.

Materials and methods: The study was conducted in Department of Oral and Maxillofacial Surgery, on 50 systemically healthy subjects (18-75 years) requiring multiple maxillary extractions. Patients were labeled into 3 groups (2% lignocaine, 4% articaine, 0.5% bupivacaine using split mouth technique. Parameters includes: Time of anesthetic onset, Duration of postoperative analgesia, Postoperative anesthesia, and visual analog scale (VAS). A volume of 1.8-2 ml of 2% lignocaine or 4% articaine or 0.5% bupivacaine was infiltrated in the buccal vestibule (local infiltration) before extraction.

Results: The results showed that time of onset of action was significantly faster in 4% articaine when compared to 2% lignocaine and 0.5% bupivacaine.

Conclusion: Articaine have being proved to have better potency and efficacy in terms of onset of action and lower pain scores comparison but lignocaine still remained the gold standard local anesthetic agent in Dental practice due to its faster time of onset, less time of anesthesia and cost effectiveness when compared articaine and bupivacaine. Bupivacaine proved more efficient in pain control and remained concentrated for major procedures.

Keywords: Articaine, Bupivacaine, Lignocaine, Maxillary extraction, Split mouth technique.

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:78-82][No of Hits : 729]


ABSTRACT

In this article, a review of the literature regarding the use of selective alveolar corticotomies (SAC) combined with orthodontic treatment was conducted, and the results of its use in a patient with overerupted maxillary 1st molars are described. Adequate intrusion was obtained within a short period of time, the protocol avoided the necessity of removal of sound tooth structure for crown lengthening, endodontic treatment, and full crown prosthetic restorations. Therefore, the obtained results indicate that SAC/orthodontic use is efficient in the intrusion of overerupted 1st molars and suggest its potential use in the treatment of other malocclusions.

Keywords: Malocclusion, Oral, Surgery, Tooth movement.

Improved Superelastic NiTi wire for the Treatment of Adult Skeletal Class III Malocclusion in a Surgery-first Case

[Year:2016] [Month:July-December] [Volumn:5 ] [Number:2] [Pages:68] [Pages No:133-138][No of Hits : 615]


ABSTRACT

A 19-year-old female came to our department with the chief complaint of facial asymmetry. Clinical examination showed skeletal class III relationship with mandibular prognathism, large reverse overjet, lower right mild crowding, and left hemimandibular elongation. After a thorough discussion with the patient, she accepted the proposal of orthognathic surgery and mandibular setback by bilateral sagittal split osteotomy (BSSRO), and therefore, tooth extraction was performed for 18, 28, 38, and 48 before the surgery. An improved superelastic Ti-Ni alloy wire (ISW wire), developed by Tokyo Medical and Dental University, was then used to facilitate the correction of lower crowding. Involved mechanism included intermaxillary elastics for a better interdigitation and jaw relationships. Adequate overbite and overjet were achieved after treatment completion.

Keywords: Improved superelastic Ni-Ti alloy wire, Orthognathic surgery-first approach, Skeletal class III.

Acute Suppurative Sialadenitis Secondary to Excisional Ranula Biopsy in Child

[Year:2016] [Month:July-December] [Volumn:5 ] [Number:2] [Pages:68] [Pages No:123-126][No of Hits : 583]


ABSTRACT

Introduction: Ranulas are lesions that affect the salivary glands, and they are generally treated by excision; however, they can recur in some cases where the gland is not removed and they may progress to acute suppurative sialadenitis, yet such cases are rare, especially in children.

Aims: To report clinical management of occurrence of acute suppurative sialadenitis secondary to excisional biopsy of ranula in a child.

Case report: An 11-year-old female patient was diagnosed with ranula where excisional biopsy was performed. Subsequently, the patient developed infection, suggesting Ludwig’s angina, after reevaluation, she was diagnosed with acute suppurative sialadenitis in the right mandibular gland; during the follow-up period, antibiotic therapy was introduced.

Conclusion: The close relationship of the biopsy site with the submandibular space and other structures of the neck required the completion of antibacterial prophylaxis associated with preoperative care, transoperative care, and postoperative care to combat opportunistic infections and their subsequent complications.

Clinical significance: Suppurative sialadenitis and its subsequent complications may be considered, although rare, as a complication in cases of ranula.

Keywords: Ludwig’s angina, Ranula, Sialadenitis.

A Randomized Controlled Trial and Radiographic Evaluation of Adjunctive Periodontal Treatment with Calcium and Vitamin D Supplementation

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:50-55][No of Hits : 578]


ABSTRACT

Aim: The objective of this study was to use clinical parameters, digital subtraction analysis, and computer intensity measurement to evaluate the effect of calcium and vitamin D supplementation in adult periodontitis patients with vertical bony defect after initial therapy.

Materials and methods: A total of 31 systemically healthy patients with moderate to severe chronic periodontitis and normal serum calcium level were included. The most obvious proximal vertical bony defect was selected in each patient as an area of interest (AOI). Subjects received initial periodontal therapy. They were randomized into two groups. The test group (n = 17) received calcium (600 mg twice daily) and vitamin D (0.25 ìg once daily) supplements for 6 months. The control group (n = 14) received placebos. At baseline and 6 months, probing pocket depth (PPD), clinical attachment level (CAL), and standardized vertical bitewing radiographs were recorded for the AOI.

Results: A greater percentage of patients in the test group (64.7%) than in the control group (35.7%) gained bone according to both radiographic evaluation methods. At baseline and 6 months, no significant intragroup or intergroup differences in PPD and CAL were observed. Slightly greater PPD reduction and CAL gain were noted in the test group.

Conclusion: Periodontal healing of vertical bony defects was better among patients who used calcium and vitamin D supplements than among control patients. Although the difference was not statistically different between the groups, the test group tended toward more improvement.

Keywords: Calcium and vitamin D supplements, Chronic periodontitis, Computer intensity measurement, Digital subtraction radiography, Vertical bony defect.

Effects of Periodontal Disease and Periodontal Treatment on the Lipid Profile: A Sri Lankan Study

[Year:2016] [Month:July-December] [Volumn:5 ] [Number:2] [Pages:68] [Pages No:127-132][No of Hits : 564]


ABSTRACT

Aims: To compare the blood lipid levels of periodontitis group (of different severities) with a nonperiodontitis group and to evaluate any influence of periodontal treatment in altering blood lipid levels.

Materials and methods: The study sample consisted of 83 patients with periodontitis in the “test” group and a matched “control” group of 40, free of periodontitis according to predetermined selection criteria. All subjects underwent periodontal assessments and blood lipid estimation prior to treatment planning, following which they received active periodontal treatment/oral prophylaxis. Twelve weeks after treatment, periodontal reevaluations were carried out and blood lipids were reassessed for pre- and posttreatment comparisons.

Results: Increases in lipid levels were observed in the periodontitis group compared to the nonperiodontitis group at baseline. The test group had 5% higher mean total cholesterol than the control group at pretreatment/preintervention (albeit not significant: Student’s t), while low-density lipoprotein cholesterol (LDL-Ch) was 6.6% higher in the test group than the control group (95% confidence interval). Mean triglycerides (Tri-G) were 5.7% higher in the control group than the test group, yet without statistical significance. All types of lipids in both the groups had decreased following periodontal therapy, while Tri-G levels demonstrated an opposite effect.

Conclusion: Patients with generalized severe periodontitis had higher LDL-Ch values than those with generalized mildmoderate periodontitis. Periodontal care was effective in lowering unfavorable serum lipids. Prompt control of periodontal inflammation would minimize development of deep periodontal infection and cardiovascular risk.

Keywords: Cardiovascular disease, Cardiovascular disease risk, Lipid profile, Low-density lipoprotein cholesterol, Periodontal treatment, Periodontitis.

Nonsurgical Approach in Periodontal Therapy for a Patient with Metabolic Syndrome

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:64-68][No of Hits : 556]


ABSTRACT

Aim: The aim of this article is to describe the effect nonsurgical periodontal therapy can have on the improvement in the glycemic and lipid indices of patients with metabolic syndrome (MS).

Background: Combination of noncommunicable diseases has become increasingly common among the people at present. Metabolic syndrome is a combination of dyslipidemia, diabetes mellitus (DM), obesity, and hypertension. Periodontal disease (PDD) is also a common entity among many people. The heightened chance of PDD in the diabetic patient is well established. Among the treatment modalities for PDD, nonsurgical therapy plays a major role. Reduction of the major causative factors of PDD can bring about a massive improvement of the disease through this approach.

Case description: Periodontal management of an adult patient with MS via nonsurgical periodontal therapy alone had shown dramatic improvement of periodontal as well as general health of the patient at the completion of the treatment.

Conclusion: Improvement of glycemic indices of diabetic patients has been shown with periodontal treatment in conjunction with medical treatment.

Clinical significance: Value of a dental professional in diagnosing metabolic diseases through detection of periodontal and other dental complications cannot be underestimated. A well-executed nonsurgical periodontal therapy alone can bring about a massive improvement of the PDD condition as well as other metabolic diseases, such as DM, emphasizing the importance of proper collaboration among the dental surgeons with the medical practitioner.

Abnormal Anatomical Location of Root of Second Premolar in Mental Foramen: A Very Rare Case

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:76-77][No of Hits : 553]


ABSTRACT

Mental foramen is a key factor in many of the surgical procedures. While carrying out surgical procedures in premolar region, the knowledge of anatomy of mental nerve and its foramen is of utmost importance to avoid intraoperative neurovascular damage and to avoid postoperative neurosensory disturbances. The variations of mental foramen with respect to position, size, and number are very well documented. However, in very rare cases, length of the premolar roots may be abnormally long or abnormally positioned, which can impinge on the mental nerve or may enter mandibular canal or mental foramen. We present one such rare case where second premolar root was impinging on the mental nerve and producing symptoms. Extraction of second premolar was done and patient became asymptomatic postoperatively.

True Fibroma on the Palate: A Unique Case

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:69-71][No of Hits : 544]


ABSTRACT

Benign fibrous overgrowths are often found in the oral cavity. Majority of the fibromas occurring in the oral cavity are reactive in nature and represent inflammatory hyperplasia of fibrous connective tissue in response to local irritation or trauma rather than being a true neoplasm. True fibroma of the oral mucosa is an extremely rare benign neoplasm, only a few cases have been reported in the literature so far. Here, we report an exceptional case of relatively large true fibroma on the palate in an 80-yearold male patient, which was mimicking a hemangioma, not reported earlier in the literature.

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:45-49][No of Hits : 523]


ABSTRACT

Dental caries affect humans of all ages, including all regions of the world and is a disease of the complex interplay of social, behavioral, cultural, dietary, and biological risk factors. The objective of this study was to determine the oral hygiene status and the prevalence of decayed, missing, and filled number of teeth (DMFT index) among madrasa going children of selected area of Dhaka city, Bangladesh. A descriptive type of crosssectional study was conducted by a purposeful selection of some madrasa with a sample size of 251. Data collection were done by four sections. Section one, two and three consist of structured questionnaire and section four resembles to DMFT index which were measured by clinical examination using an examination form. Seventy percent of children had experienced dental caries with mean DMFT score of 1.94. Female children had higher DMFT score than male children. There was a highly significant association between tooth brushing frequency and family income of respondents with caries. We conducted this study in madrasa because up till now such study has not been performed. These data on oral health status and prevalence of DMFT will certainly helps to determine the appropriate treatment plan for madrasa going children. For the benefit of a community, dental health programs need to be conducted repeatedly in order to reach the goals of the World Health Organization (WHO).

Porphyrin and Pentosidine Involvement in the Red Fluorescence of Enamel and Dentin Caries

[Year:2016] [Month:January-June] [Volumn:5 ] [Number:1] [Pages:82] [Pages No:1-10][No of Hits : 522]


ABSTRACT

Proper treatment of dental caries demands detection of carious lesions at an early stage and a minimal invasive cavity preparation to preserve the maximum tooth structure. Various devices use fluorescence for caries detection via recording the red fluorescence generated by dentin caries under illumination.
The aim of this study was to evaluate the porphyrin and pentosidine involvement in the red fluorescence observed in enamel and dentin caries when illuminated with the Soprolife® camera (Sopro, Acteon Group, La Ciotat, France) and Vistacam® camera (Dürr Dental AG, Bietigheim-Bissingen, Germany). Three techniques were used: single photon fluorescence spectroscopy, micro-Raman spectroscopy, and color analysis with ImajeJ software. Cross-sections of human teeth, scored from 0-6 with the International Caries Detection and Assessment System (ICDAS), were examined by fluorescence microscopy. Teeth spectra of each ICDAS score were compared with those of protoporphyrin IX (PpIX), porphyrin I, and pentosidine solutions. A specific confocal Raman microscopy analysis was realized and a Red-Green-Blue model analysis of Soprolife® images was performed using ImageJ software to compare the color variations on ICDAS score 1 and 2. Fluorescence spectroscopy and micro- Raman spectroscopy revealed the presence of PpIX in carious enamel and dentin. The clinical relevance of this experimentation was that the increased knowledge of the fluorescence aids for caries detection could improve the preventive approach, thus reducing the operative one.

Keywords: Caries detection, Fluorescence spectroscopy, Maillard reaction, Porphyrin, Raman spectroscopy, Soprolife®/ Vistacam® cameras.

ABSTRACT

The mental foramen is defined as the entire funnel-like opening in the lateral surface of the mandible at the terminus of the mental canal. The location of the mental foramen is of high significance while giving nerve block technique for adequate pain control to perform surgical procedures. Many studies have been conducted across the world, and a wide range of literature has been published on this topic. This study aims to determine the position of the mental foramen in southern Saudi Arabian population. This would act as a guide while anesthetizing the mental nerve and also in preserving the nerve while performing surgical procedures in this region.

Third Molar Socket Grafting after Surgical Extraction to prevent Periodontal Pocket Formation

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:65-68][No of Hits : 2245]


ABSTRACT

There is an incidence of periodontal pocket formation and gingival recession on the distal of the lower second molar due to bone defect after third molar surgical removal. Patient referred suffering from recurrent pericoronities; after clinical and radiographic examination, the lower left 3rd molar is partially erupted and angulated in mesial direction. The radiograph shows there is bone deficiency on the distal of the adjacent 2nd molar. After 3rd molar surgical removal, cancellous bone graft placed on the socket with guided bone regeneration (GBR) procedure and complete primary closure with rotational flap. Patient follow-up after 3 and 6 months, bone formation observed on the distal of 2nd molar with the absence of periodontal pocket. Third molar socket bone grafting with cancellous allograft may be a predictable procedure to prevent periodontal pocket on the distal of the second molar.

Fibrin Sealant: A Review of Its Applications in Periodontal Surgery

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:40-46][No of Hits : 2137]


ABSTRACT

Aim: Fibrin sealant is a biological tissue adhesive mimicking the final stage of coagulation. It has a wide variety of application in the field of periodontics. The aim of this article was to review current applications and identify potential use of fibrin sealant in periodontal surgical procedures on an evidence-based conclusion.

Materials and methods: An online search was performed in PubMed, Google Scholar and Cochrane Library databases using keywords fibrin sealant, fibrin glue, fibrin, regeneration, wound healing, tissue adhesive, gingival recession/therapy, surgical therapy, periodontal, and periodontitis in a mutually inclusive manner. The studies were evaluated by two independent reviewers for inclusion in this literature review.

Results: Out of 196 research papers identified, 59 articles were selected by the authors for this literature review, giving preference to clinical trials related to periodontal application.

Conclusion: Use of fibrin sealant is a simple, safe, costeffective, and rapid way to fix flaps and grafts avoiding any postoperative bleeding. Fibrin sealant has the property for regeneration when used in conjunction with a barrier membrane for formation of new connective tissue attachment. It is effective in microsurgical procedures and closing flaps around implant site. They initiate early wound healing through collagen synthesis and fibroblast proliferation. Fibrin sealant may be an alternate biomaterial for periodontal surgery which may stimulate periodontal wound healing and regeneration.

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:33-39][No of Hits : 2087]


ABSTRACT

Aim: The present study was aimed to evaluate the efficacy of calculus/tartar dissolution based oral rinse as an adjunct to toothbrushing in gingivitis patients for long-term effects on new supragingival calculus formation.

Materials and methods: After undergoing a dental prophylaxis, 60 gingivitis subjects with a moderate rate of calculus formation were stratified and randomly assigned to one of two groups: Control group (regular dentifrice alone) and experimental group (using a regular dentifrice and a calculus/tartar control mouthrinse). Subjects brushed and rinsed twice daily, unsupervised, for 6 months. All subjects were assessed with gingival index (GI), plaque index (PI) and calculus levels using the Volpe-Manhold Index (VMI) after 3 and 6 months.

Results: Statistical analysis found that the experimental group (which used a calculus/tartar contain mouthrinse) demonstrated statistically significantly lower VMI scores (p = 0.001) than control group (which used a regular dentifrice alone). In experiment test group A, there was decline in VMI score from 3 to 6 months by 23.12% as compared to group B where there was continuous increase in VMI scores from 3 to 6 months by 22.16%.

Conclusion: A mouthrinse containing tetrapotassium pyrophosphate and sodium tripolyphosphate as the anticalculus agent provides a clinically relevant reduction in calculus formation in subjects with a moderate rate of such formation.

Esthetic Rehabilitation of Mutilated Anterior Teeth with Custom Cast Post and Core Porcelain-Fused-to-Metal Crowns

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:69-71][No of Hits : 1488]


ABSTRACT

An endodontically treated anterior tooth requires extracoronal restoration when the tooth structure is weakened or lost due to caries, endodontic treatment, placement of previous restorations and/or is discolored. The reduced tooth structure makes retention of extracoronal restoration difficult. The purpose of post is to provide retention for the core restoration, which replaces lost coronal structure. This article describes restoration of mutilated maxillary central incisors by using cast post and core, followed with porcelain fused to metal restorations.

Anterior Middle Superior Alveolar Nerve Block Efficacy Utilizing different Anesthetic Solutions, Reduced Dosage and Conventional Syringe: A Breakthrough in Pain Control

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:80-86][No of Hits : 1349]


ABSTRACT

Introduction: For over a decade of introducing the anterior middle superior alveolar (AMSA) injection, it has since majorly only been reported to show both pulpal and buccal mucosal effectiveness using a minimum of 0.9 ml of anesthetic solution.

Aim: The aim of this study was to demonstrate the AMSA nerve block efficacy using a reduced dosage and conventional syringe, while comparing the anesthetic effectiveness of lidocaine vs mepivacaine. A primary objective was to understand the behavioral difference between the two solutions, to better adapt their application into relevant clinical scenarios, where fewer injections are administered, pain control is better understood and implemented, and collateral anesthesia altering the natural lip line is eliminated.

Materials and methods: Twelve candidates (both sexes), of ages 18 to 24, were selected. All the participants received bilateral AMSA nerve block (split-mouth technique) using the conventional syringe, where 0.6 ml of lidocaine and mepivacaine 2% with epinephrine 1:100,000 were randomly administered to each side.

Results: Pulpal anesthesia on both premolar teeth showed 83.3% success within 15 minutes with lidocaine group (LG) and mepivacaine group (MG) alike. Buccal anesthesia at both premolar teeth showed 50% success within 15 minutes with LG and 54.2% with MG. There was no difference in anesthetic effectiveness between the two groups in pulpal anesthesia (p ≥ 0.05), and no significant difference in buccal mucosal anesthesia (p ≥ 0.05).

Conclusion: No statistically significant difference was observed between lidocaine and mepivacaine, while both expressed anesthetic effectiveness using a reduced dosage, as well as near painlessness using the conventional syringe.

Sedation of Uncooperative Pediatric Dental Patients

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:29-32][No of Hits : 1233]


ABSTRACT

The approach to managing the behavior of children in the dental environment must be based on empathy with a child in order to understand why the child is distressed, anxious or afraid.
Any dentist treating children needs a spectrum of behavioral techniques from the simplest-tell and show all the way through to a full general anesthetic. Its use is indicated in specific situations and used only when appropriate.
On this basis, the caring dentist discusses with the parent the likely need for various behavioral techniques in the child’s management. In this study, we show our experience with oral and nasal sedation in a group of pediatric uncooperative dental patients.

Nonsurgical Correction of Skeletal Class III Malocclusion by Multibends Edgewise Archwire Technique in an Adult

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:137-142][No of Hits : 1037]


ABSTRACT

Skeletal class III malocclusion treated with orthognathic surgery usually can achieve a better facial profile and stable occlusion outcome. We describe a 37-year-old patient who sought orthodontic treatment for skeletal class III, but refused recommendations for orthognathic surgery because of personal considerations. After careful analysis of the X-ray images and study models, this patient was subjected to active orthodontic treatment to correct malocclusion using upper and lower arch with improved superelastic NiTi alloy wire (ISW) for efficient leveling of the teeth. In the lower arch, the multibends edgewise archwire (MEAW) technique was used to tip back and intrude the canine and posterior teeth. After the completion of treatment, anterior teeth crossbite was successfully corrected and proper occlusal relationships were reestablished.

Keywords: Improved super elastic NiTi alloy wire, Intermaxillary elastics, Multibends edgewise archwire.

A Comparison of Methods for Increasing Retention of Complete Veneer Crowns

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:95-98][No of Hits : 876]


ABSTRACT

Aim: To determine if boxes or grooves were effective in enhancing the retention of full veneer crowns.

Materials and methods: Ten full veneer crown preparations were machined out of brass with 10 different configurations. They consisted of a plain short preparation, a plain long preparation and preparations with 1 to 4 boxes or 1 to 4 grooves. Ten gold castings were fabricated for each preparation and the cemented. An Instron* was used to remove the castings with the force required recorded in Newtons.

Results: Statistical differences were found in retention between various configurations with boxes being universally more retentive than grooves or the plain crowns.

Conclusion: All the box configurations significantly enhanced retention. Therefore, one box alone would provide the enhanced retention needed for a full veneer crown without the need to create additional retention features.

Keywords: Box, Crown, Groove, Retention.

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:116-118][No of Hits : 864]


ABSTRACT

Aim: This pilot study was aimed to evaluate the efficacy of sea salt-based oral rinse as adjunct with conventional oral hygiene measures in gingivitis patients in terms of clinical parameters.

Materials and methods: A total 30 gingivitis patient between the ages of 18 and 55 years were enrolled in the study and divided under two categories. Clinical parameters were recorded prior to phase one therapy; and subjects were put on different oral hygiene regime with and without sea salt-based mouth rinse. At baseline and 3rd month subjects were evaluated.

Results: The results of this study showed that there was significant decrease in clinical parameters from baseline to 3 months in both the groups (p < 0.01). The subjects under groups using sea salt-based mouthwash showed a highly significant reduction to all the parameters as compared to subjects under groups using a conventional toothbrushing only.

Conclusion: Thus, we can conclude that long-term regular use of sea salt-based product seems to be more beneficial.

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:119-123][No of Hits : 861]


ABSTRACT

Objectives: To investigate periodontal status and the relationship between obesity and periodontal status in female patients who first visited the Traditional Medicine Institute, Ho Chi Minh city, Vietnam.

Materials and methods: One hundred and three female patients aged 18 or older, including 45 obese subjects and 58 nonobese subjects were enrolled in a period of 5 months from February to June 2014. The information on sociodemographic characteristics and dental habits were collected by questionnaire. Periodontal status [plaque index (PI1), gingival index (GI), bleeding on prabing (BOP), pocket depth (PD), clinical attachment level (CAL)] was examined and the anthropometric index was measured.

Results: There was significantly higher prevalence of periodontitis (40.0%) in obese females than nonobese females (13.8%). The means values of periodontal parameters in obese females were significantly higher than those in nonobese females. Significantly, higher percentage of subjects who did not use dental flossing, or less regularly visited dental offices, or less regularly had their teeth scaled and polished was in the obese group than those in the nonobese group. Multiple logistic regression analysis revealed that age [odds ratio (OR = 3.60)], routine of dental visit (OR = 3.75) and obesity (OR = 3.46) were significantly related to periodontitis.

Conclusion: Periodontal status in obese subjects was poorer than nonobese ones. Obesity, age and dental visit were associated with periodontitis in Vietnamese female patients.

Comparison of Fungal Biofilm Formation on Three Contemporary Denture Base Materials

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:104-108][No of Hits : 748]


ABSTRACT

Statement of problem: Modern polyamide ‘flexible’ denture base materials have increased in popularity for use in removable partial dentures in the last several years. The introduction of these newer products warrants investigation of their relative potential to develop fungal biofilms.

Purpose: The purpose of this study was to investigate the potential of three denture base materials to support fungal biofilm formation.

Materials and methods: Specimens of two ‘flexible’ nylon type materials and one traditional heat processed, methyl methacrylate resin material were studied (both polished and unpolished surfaces). The specimens were coated with saliva and evaluated for fungal (Candida albicans) biofilm formation. The fungal biofilm mass formed on denture substrates were evaluated by dry weight analysis and by determining the number of viable fungal cells in the biofilm by MTT viability assay. Alteration in fungal metabolic function following the treatment of the biofilm C. albicans with nystatin and fluconazole was determined by XTT assay.

Results: In general, the unpolished surfaces of the denture disks favored the fungal biofilm, the most being on polyamide specimen, Valplast. Significantly, less biofilm was formed on Duraflex and Lucitone surfaces. Biofim on C. albicans was also found to be resistant to antifungal agents. As compared to freshly incubated (grown) planktonic cells, biofilm fungal cells required significantly higher concentrations of nystatin and fluconazole in order to obtain 50% reduction in metabolic activity.

Conclusion: This study demonstrated the differences in denture materials to support fungal biofilm formation, and also difference between polished and unpolished denture material surfaces. The results demonstrated that one of the polyamide materials (duraflex) had lesser potential to biofilm formation than the others.

Clinical significance: Unfavorable tissue responses can ensue from the presence of fungal biofilms on dental prosthetics. Resistance to biofilm formation is a factor for dental materials in their selection and usage. This study helps to quantify, evaluate and compare biofilm formation on polished and unpolished surfaces of three commonly used denture base materials. The results of this study helped to identify materials, which may, therefore, be better indicated in clinical applications. Evaluations for the newer denture base materials, specific to these testing methods, appear to be novel in the scientific literature.

Associations between Periodontal Disease Parameters and Coronary Heart Disease in Greek Adults: A Cross-sectional Study

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:4-10][No of Hits : 647]


ABSTRACT

Aim: Several forms of periodontal disease have been associated with the development of coronary heart disease. The current retrospective study was conducted to investigate the possible relationship between periodontal disease parameters and defined coronary heart disease (CHD) in Greek adult patients.

Materials and methods: The study sample consisted of 880 individuals, 400 males and 480 females, aged 40 to 78 years. Data were collected by means of an interviewer administered questionnaire and an oral clinical examination. Statistical analysis of the questionnaire items was performed by using multiple regression analysis model in order to assess possible associations between coronary heart disease as dependent variable and epidemiological variables, biomarkers and periodontal disease parameters as independent variables.

Results: The occurrence of hypertension (OR = 0.01, 95% CI = 0.09-1.33), high level of triglycerides (OR = 0.08, 95% CI = 0.06-2.27) and total cholesterol (OR = 0.08, 95% CI = 0.07- 1.27), low level of high-density lipoprotein (OR = 0.12, 95% CI = 0.09-3.70) and smoking (OR = 1.83, 95% CI = 0.38-8.88) were significantly associated with the presence of coronary heart disease, whereas the periodontal parameters examined were not associated with the occurrence of it.

Conclusion: No associations were observed between periodontal disease parameters and defined coronary heart disease. However, the recorded associations strengthen the role of hypertension, lipids and smoking as causative risk factors of coronary heart disease.

Management of Invasive Cervical Resorption Involving the Pulp by Surgical and Restorative Therapy

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:130-133][No of Hits : 646]


ABSTRACT

Invasive cervical resorption (ICR) is a form of external resorption which affects the cervical area of permanent teeth and may progress to involve the pulp. It can cause insidious loss of tooth structure, which often is undetected until late in the process. Two cases, both involving the maxillary left central incisor where cone-beam computed tomography (CBCT) revealed an invasive cervical resorptive lesion, extending from the cervical to mid root region and perforating the pulp chamber. The cases were managed surgically with the help of a dental operating microscope (DOM). Nine months follow-up revealed resolution of the lesion and restoration of the affected teeth to functional occlusion. This report emphasizes the restorability of advanced lesions of ICR, if adequate diagnostic and treatment equipment is used.

Low Xylitol Concentration induces Ultrastructural Cellular Changes in Streptococcus mutans and Streptococcus sobrinus

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:1-3][No of Hits : 645]


ABSTRACT

Background: Xylitol is a sugar alcohol frequently used in the prevention of dental caries. However, the mechanism of action of xylitol on mutans streptococci is still unclear. This study evaluated the ultrastructural cellular changes in Streptococcus mutans and Streptococcus sobrinus after xylitol treatment.

Materials and methods: S. mutans ATCC 25175 and S. sobrinus ATCC 33478 were grown separately in BHI medium plus 0.2% sucrose at 37°C under microaerophilic conditions overnight. Then, planktonic cells were harvested by centrifugation, resuspended in a fresh medium and incubated with either 0.2% glucose or 0.2% xylitol solutions for 2 hours. To prepare bacterial cells for the evaluation of morphology of cellular walls and polysaccharide capsules, cultures were subsequently fixed with 2.5% glutaraldehyde, stained with ruthenium red, post-fixed with 1% osmium tetroxide, dehydrated in acetone, embedded in Epon LX112 and analyzed by a transmission electron microscopy.

Results: Bacterial cells incubated with glucose showed welldefined cellular walls and well-stained cytoplasmic membrane. Unlike, xylitol yielded diffuse cellular wall and irregular polysaccharide capsules in both microorganisms.

Conclusion: Low xylitol concentrations also can induce cellular damage to both S. mutans and S. sobrinus. Further studies are needed to provide more evidence on the anticariogenic effect of xylitol.

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:87-94][No of Hits : 637]


ABSTRACT

Objective: The aim of this pilot study is to evaluate to value of primary implant stability for two-piece zirconia implants and longitudinally stability changes of implants during the healing period of 16 weeks.

Materials and methods: Ten patients treated with 12 two-piece non metallic zirconia dioxide root shape implant ( Ө4/10 mm, Axis Biodental, Les Bios, Switzerland) for single tooth replacement in the upper premolar area. Resonance frequency analysis (RFA) was used for assessment of longitudinally changes of implant stability during 16-weeks observing period. All patients have been re-evaluated 1 year after loading.

Results: Mean implant stability quotient (ISQ) value of initial implant stability for 12 implants was 60.25 (3.72). Statistically, significant decrease was noted in the first 3 weeks after insertion (p = 0.000). Also, statistically significant increasing of implant stability was recorded for observing period for 6th to 16th week.

Conclusion: Increasing of ISQ value during observing period suggests loading of two-piece zirconia dioxide root shape implant for single tooth replacement in the upper premolar area, after healing period of 4 months.

Dynamics of Matrix Metalloproteinases in the Oral Environment

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:53-57][No of Hits : 625]


ABSTRACT

Matrix metalloproteinases (MMPs) are an important family of zincdependent endopeptidases that mediate the extracellular matrix (ECM) degradation. The major component of the extracellular matrix, collagen, is catabolized. These enzymes have been implicated in oral pathologic processes, such as periodontal tissue destruction, root caries, tumor invasion, and temporomandibular joint disorders. The aim of this paper was to review of some general aspects of matrix metalloproteinases and discuss the role of these enzymes in normal physiology and pathology with emphasis on the oral environment. This process is important in a number of aspects of dentistry since matrix is constantly turning over. Although the members of the MMP family matrix possess different substrate specificities, they all possess similar structural and functional features and demonstrate similar mechanisms of proteolysis. The catalytic of the MMPs is regulated at multiple levels including transcription, secretion, activation and inhibition. The growth and repair of connective tissues is a delicately balanced process of ECM removal and replacement with significant control by primary MMPs and their natural inhibitors, the tissue inhibitors of metalloproteinases (TIMPs). Dentists have a need to understand matrix turnover in the periodontal ligament and adjacent structures, embryology and development.

Degradation of the Strength of Elastomeric Chains subjected to Different Levels of Salivary pH associated with Exposure to Mouthrinses with and without Fluoride

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:23-28][No of Hits : 619]


ABSTRACT

Aim: To evaluate the degradation of strength of elastomeric chains submitted to different levels of salivary pH and exposed to mouthrinses with and without fluoride.

Materials and methods: Seven groups of chain elastics (n = 18) mounted on test devices that remained immersed in artificial saliva were tested. Group 1 (pH 5 and without fluoride), 2 (pH 5 and with fluoride), 3 (pH 6 and without fluoride), 4 (pH 6 and with fluoride), 5 (pH 7.5 and without fluoride) and 6 (pH 7.5 and with fluoride) and 7 (control group). The test groups were exposed to mouthrinses twice a day for 30 seconds, with an interval of 12 hours between one exposure and the other. A control group was immersed in distilled water. The strength of samples was gauged with a dynamometer. Six measurements of strength were made in the following time intervals: initial (0), 1, 7, 14, 21 and 28 days. The force values were submitted to the analysis of variance (ANOVA) and Tukey’s test to determine whether there were statistical differences between each group. The level of significance adopted was 5% (α = 0.05).

Results: When the groups were evaluated individually, comparing the factor time in the initial period, the force was statistically higher than that in all the other experimental time intervals (p < 0.05). From the 7th day up to day 28, no statistical differences were found among the groups (p > 0.05). The factors pH and the presence of mouthwash with or without fluoride did not interfere in the results among the groups (p < 0.05).

Conclusion: The presence or absence of fluoride in the mouthrinses used in the study made no difference to the force degradation of the chain elastics, as the test groups obtained similar results among them in the studied time intervals.

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:134-136][No of Hits : 582]


ABSTRACT

Pyogenic granuloma (PG) is one of the inflammatory reactive hyperplasia affecting the oral tissues. It is a relatively common mucocutaneous lesion seen in the oral cavity. It is predominantly seen in young females. Soft tissue enlargements of the oral cavity often represent a diagnostic challenge, because a diverse group of pathologic processes can produce such lesions. An enlargement may represent a variation of normal anatomic structures, inflammation, developmental anomalies, cyst and neoplasm. Here, we report an exceptional case of PG of unknown etiology in 8-year-old male child patient in alveolar crest associated with bone resorption and displacement of tooth bud.

Cytotoxic Effects of Three Denture Base Materials on Gingival Epithelial Cells and Fibroblasts: An in vitro Study

[Year:2015] [Month:January-June] [Volumn:4 ] [Number:1] [Pages:76] [Pages No:11-16][No of Hits : 543]


ABSTRACT

Objectives: Modern polyamide ‘flexible’ denture base materials have increased in popularity for use in removable partial dentures. The introduction of these new products warrants investigation of their relative potential for toxicity. The purpose of this study was to investigate three contemporary denture base materials used in fabricating definitive prosthetic restorations.

Materials and methods: Two ‘flexible’ materials (Valplast and Duraflex) formed by thermoplastic injection molding technique, and one traditional heat processed, methyl methacrylate resin material (Lucitone 199) were evaluated. Cultured gingival epithelial cells and fibroblasts were treated with conditioned media prepared from denture material disks and then assayed for cell toxicity by [3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide] (MTT) cell viability assay. Cell membrane damage was determined by measuring the release of cytoplasmic lactate dehydrogenase. Further confirmation of toxicity induced by the conditioned media was determined by staining the cells with live/dead stain and observing under a UV microscope.

Results: Data were analyzed by means of a linear model ANOVA followed by Tukey’s post hoc tests for comparison among groups. The significance level adopted was 5% (p < 0.05). The three denture materials differed in their toxicity to the cells as assessed by MTT assay. Valplast conditioned media in general, especially the media of unpolished disks, was found to be toxic to both gingival fibroblasts and epithelial cells while media obtained from polished Lucitone and Duraflex were found to be less toxic. After 7 days of incubation with Valplast unpolished conditioned media, only 1 to 2% of the cells remained viable, while the polished disk conditioned media caused significantly less (p < 0.05) toxicity, approximately 76 and 92% of fibroblasts and epithelial cells respectively, were viable. After 7 days of incubation with media obtained from the other denture materials, 35 to 92% of fibroblasts and epithelial cells were found to be viable. The data obtained from lactate dehydrogenase (LDH) assay and live/dead mammalian cell viability assay were in agreement with the MTT viability assay.

Conclusion: Conditioned media from unpolished Valplast denture material appeared to be significantly more toxic to gingival fibroblasts and epithelial cells when compared to the polished Lucitone disk conditioned media as well as the media obtained from Duraflex.

Influence of Color on Attractiveness of Petit Facial Mask

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:99-103][No of Hits : 528]


ABSTRACT

Aims: Evaluate the esthetic attractiveness of the Petit type facial masks of different colors among youngsters from public and private schools.

Materials and methods: Eight orthopedic facial masks of the Petit type, in different colors were evaluated. Images were obtained of the same patient, and were standardized with a program for changing images (Adobe Photoshop software from CS). The following colors were inserted in the masks: white, gray, green, yellow, blue, pink, orange and black. After acquisition, the images were printed on photographic paper and incorporated into a specific and personalized questionnaire. The questionnaire was distributed among children of both genders, in the age ranges from 7 to 8, and 9 to 10 years, at public and private schools (n = 200). For the scores attributed to each image, the Mann-Whitney test was used, and among groups, Spearman’s correlation. The level of significance adopted was 5%.

Results: Only the scores attributed to the color brown presented significant difference between the schoolchildren from public and private schools. In a comparison between genders, the boys awarded better scores to the colors gray, blue and black, whereas the girls awarded better scores to the color pink. When comparing the age ranges examined there were no statistical differences.

Conclusion: The color of the Petit type of facial mask has an influence on the esthetic attractiveness to children from 7 to 10 years, and preference for certain colors is also influenced by gender and the type of school (public or private).

What is the Effect of Implant-tooth Distance on Resonance Frequency Analysis Measurements?

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:124-129][No of Hits : 522]


ABSTRACT

Objectives: The volume and density of the bone surrounding an implant directly affect the implant stability during the healing period.
The aim of this study was to determine the correlations between resonance frequency analysis (RFA) readings and implant-tooth distances at the crestal and average apicalcrestal levels.

Materials and methods: Nine patients received 22 implants. Periapical radiographs were taken at 6 weeks, and the implant-tooth mesial and distal crestal level distances were measured, along with the mesial and distal apical levels. The average mesial (AM) and average distal (AD) apical-crestal distances were calculated. In cases in which either the AM or the AD of the implant was below 4 mm, the specimens were placed in the AMD– group; when both the AM and the AD were greater than 4 mm, the specimens were placed in the AMD+ group. The lower values were used for both groups. Resonance frequency analysis measurements were taken in the mesiodistal direction at 6 weeks. The correlations between the mean RFAs and the means of the distances were examined using Spearman’s or Pearson’s correlation tests, depending on the distributions of the data.

Results: The mean and SD of the AD group was 3.99 ± 3.19. The mean and SD of the AM group was 3.80 ± 2.67. The mean and SD of the AD– group was 2.72 ± 0.89. The mean and SD of the AD+ group was 6.34 ± 2.94. The mean and SD of the RFAs at 6 weeks was 77.82 ± 5.24, and for the AMD– and AMD+ groups, these measures were 78 ± 5.55 and 77.64 ± 5.36, respectively. None of the correlations between the RFAs and any of the distances were significant: AD (r = 0.114; Pearson’s test, p < 0.05), AM (r = – 0.217; Spearman’s test p < 0.05), AMD– (r = 0.248; Pearson’s test, p < 0.05), and AMD+ (r = 0.3; Spearman’s test, p < 0.05).

Conclusion: Within the limitations of this study, no correlations between the RFA readings and the implant-tooth distances were found at any level or distance.

Keywords: Correlation, Implant-tooth distance, Implant stability, Resonance frequency analysis.

[Year:2015] [Month:July-December] [Volumn:4 ] [Number:2] [Pages:68] [Pages No:77-79][No of Hits : 504]


ABSTRACT

Background: Oral health status of prisoners has been an area of concern worldwide. The prison population is unique in nature because of the complexities of their psychological, social and behavioral aspects. Limited oral healthcare facilities in prison settings have resulted in neglect of oral health among prisoners.

Aim: The present study aims to assess oral mucosal lesions among prisoners in Central Prison, Chennai.

Materials and methods: A cross-sectional epidemiological survey was conducted in Central Prison, Puzhal, Chennai. The study population consisted of 1060 prisoners from three divisions of the Central Prison. Oral mucosal lesions among the prisoners were assessed by a single investigator according to World Health Organization (WHO) specifications.

Results: The present study shows that among the study subjects, 37.7% of males and 17.1% of females developed oral mucosal lesions. The prevalence of smokers melanosis was 27.6% among males and 8.6% among females. The prevalence of oral mucosal lesions was found to be highest in study subjects of 55 years and above.

Conclusion: A large proportion of the study subjects had oral mucosal lesions. Oral mucosal lesions like oral submucosis fibrosis, smokers palate and smokers melanosis was found to be common among males than females. Oral healthcare facilities should be incorporated in prison settings which would intercept the progress of oral mucosal lesions.

Keywords: Chennai, Oral lesions, Oral submucous fibrosis, Prisoners.

Molar Incisor Hypomineralization

[Year:2014] [Month:January-June] [Volumn:3 ] [Number:1] [Pages:58] [Pages No:37-40][No of Hits : 2986]


ABSTRACT

Developmental defects of tooth enamel are not uncommon, both in the primary and permanent dentition. An example of idiopathic enamel defect is molar incisor hypomineralization (MIH). The condition is defined as a hypomineralization of systemic origin of one to four permanent first molars frequently associated with affected incisors. The prevalence of MIH is reported to vary between 2.4 and 40.2% in normal child populations. Management consists of early diagnosis, prevention of caries or posteruptive breakdown and interception if caries or breakdown has already ensued. Management challenges include difficulty in obtaining adequate anesthesia, increased incidence of caries, early pulpal involvement and gross destruction of clinical crown of affected teeth. In young permanent teeth, semipermanent crowns like stainless steel crowns for posterior teeth and direct composite veneering for anterior teeth are the recommended solutions.

Keywords: Molar incisor hypomineralization, Dioxins, Cheesy molars.

Comparison of Effects of Tooth Extraction and Air-rotor Stripping Therapy on Tooth-size Discrepancy in Class I Borderline Patients

[Year:2014] [Month:January-June] [Volumn:3 ] [Number:1] [Pages:58] [Pages No:8-13][No of Hits : 2582]


ABSTRACT

Aim: The objectives of this study were to investigate the effects of tooth extraction and air-rotor stripping therapy on tooth-size discrepancy, and to compare the changes between two groups.

Materials and methods: The sample comprised the pre- and post-treatment dental models of 20 postadolescent class I borderline patients. First group was composed of dental models of 10 patients (mean age of 17.1 ± 2.5 years) treated with four first premolars extraction. Second group included dental models of 10 patients (mean age of 18.8 ± 2.7 years) treated with air-rotor stripping. Treatment effects on Bolton overall and anterior ratios/values were analyzed by paired sample t-test and independent sample t-test was used for intergroup comparisons.

Results: The change in Bolton overall ratio was found statistically significant for the extraction and insignificant for the air-rotor stripping group. A statistically significant decrease was observed in Bolton anterior ratio for the air-rotor stripping group. Neither four premolars extraction nor air-rotor stripping therapy created statistically significant changes in Bolton overall/anterior values. The changes in Bolton overall ratio/value did not show a statistically significant difference between the groups.

Conclusion: This study showed that tooth extraction or air-rotor stripping therapy did not have an unfavorable effect on toothsize discrepancy in class I borderline patients.

Keywords: Tooth extraction, Air-rotor stripping, Tooth-size discrepancy, Class I, Borderline patients.

Repositioning of the Mental Nerve in Case of Severe Mandibular Atrophy: A Case Series

[Year:2014] [Month:January-June] [Volumn:3 ] [Number:1] [Pages:58] [Pages No:41-43][No of Hits : 2154]


ABSTRACT

Following tooth extraction, cortical bone suffers greater resorption on the vestibular area and patients typically present narrow and low alveolar crests. In case of moderate to severe mandibular atrophy; the bone height between alveolar crest and mental nerve is too narrow and patients may feel pain under pressure. Repositioning of the mental nerve is an effective preprosthetic surgery procedure in patients with hyperesthesia caused by dental prosthesis. As well as this surgical repositioning of the mental nerve facilitates the placement of implants can prevent pain, in overdenture prosthesis and fixed dentures. In this report, mental nerve repositioning, implant placement in the interforaminal region of the mandible and prosthetic rehabilitation of two cases with hyperesthesia due to severe mandibular atrophy is presented. Nerve repositioning may constitute a treatment alternative in patients with a consequent risk of mental nerve damage during the placement of dental implants.

Conservative Treatment of Dentigerous Cysts in Childhood

[Year:2014] [Month:January-June] [Volumn:3 ] [Number:1] [Pages:58] [Pages No:14-18][No of Hits : 2009]


ABSTRACT

Objectives: Developmental odontogenic jaw cysts are generally connected with impacted or unerupted teeth. The conservative treatment options of these types of cysts will be presented.

Study design: In this study 17 cases operated in Süleyman Demirel and Selcuk Universities Faculty of Dentistry were included. The data of the cases were documented with respect to age, sex, localization, symptoms, presence of unerupted teeth on panoramic radiographs. The cysts were treated with marsupialization with an obturator made of acrylic resin in nine patients and a tube drain in eight patients to keep the window open.

Results and conclusion: Marsupialization was evaluated as extremely effective in 15 patients, the cysts completely disappeared and the permanent teeth were erupted, in two patients the cysts disappeared but the teeth were not erupted.
Enucleation, marsupialization or their combination are the conventional treatment options of the jaw cysts. Large cysts may localize nearby the important anatomical structures or may involve unerupted permanent teeth. These kind of cysts may be treated with marsupialization in order to protect these anatomical structures or to allow the eruption of the permanent teeth.
Marsupialization should be considered as an effective conservative treatment method of the jaw cysts during mixed dentition in the childhood.

Keywords: Children, Conservative, Dentigerous cyst, Impacted teeth, Marsupialization.

Antibiotic Resistance — What can the Dental Care Sector do?

[Year:2014] [Month:July-December] [Volumn:3 ] [Number:2] [Pages:61] [Pages No:vii-viii][No of Hits : 1868]


ABSTRACT

Antibiotic Resistance - What can the Dental Care Sector do?
The development of drug-resistant pathogens is extremely alarming. Today, infections that have been regarded as fairly mundane for many decades can in the worst case lead to a patient’s death. In Europe alone, 25,000 people die every year from infections that cannot be cured because of antibiotic resistance. Even with modern high-tech healthcare, where the capacity to cure diseases and save human lives has increased dramatically, the risks to the health and lives of patients as a result of infections that do not respond to any antibiotic are now very real.

[Year:2014] [Month:January-June] [Volumn:3 ] [Number:1] [Pages:58] [Pages No:19-23][No of Hits : 1794]


ABSTRACT

Aim: Xerostomia is an important complication following radiotherapy for head and neck regions producing serious discomfort for patients. Symptomatic treatments for the disease include strict oral hygiene and use of artificial saliva substitutes. The present study compared the efficacy of BioXtra spray and mouthwash in the relief of radiotherapy-induced xerostomia in patients referred to Imam Khomeini Hospital, Tehran University of Medical Sciences.

Materials and methods: In a cross-over randomized clinical trial, BioXtra spray and mouth wash were used by 20 patients for 2 weeks with a 1 week wash-out period. The ease of application and the patients' acceptance of the products were obtained using 100 mm visual analog scale (VAS) and dichotomous scales. We used SPSS version. 18.0 to analyze our data considering level of significance less than 0.05.

Results: Both forms of BioXtra showed similar effect in reducing oral dryness and its complications. The mean VAS was 33.2 for spray and 34.5 for mouthwash. Majority of our patients reported improvements in xerostomia after using spray (85%) and mouthwash (70%), respectively. The patients' acceptance of both modalities was similar and they showed equal tendency to continue the treatments. No significant differences in symptoms relief as well as judgment of the regimens were found between groups.

Conclusion: BioXtra spray and mouthwash are similarly effective in reducing the symptoms of postradiotherapy xerostomia.

Keywords: Xerostomia, Radiation therapy, BioXtra.

Can Enhanced Peroxides Decrease the Side Effects of Tooth Bleaching? A Systematic Review of the Literature

[Year:2014] [Month:July-December] [Volumn:3 ] [Number:2] [Pages:61] [Pages No:84-91][No of Hits : 1703]


ABSTRACT

Adverse effects of tooth bleaching on dental structures remain a topic of discussion in the literature, and the search for protocols that reduce such reported adverse effects is ongoing. The goal of this systematic literature review was to determine whether the use of tooth bleaching gels with added minerals, such as fluoride, calcium, hydroxyapatite, potassium nitrate, amorphous calcium phosphate, and casein phosphopeptide-amorphous calcium phosphate, reduced the occurrence of the main adverse effects of tooth bleaching. The electronic database search identified 16 studies that evaluated the effects of bleaching gels with added minerals on enamel hardness and/or roughness, mineral loss, post-treatment sensitivity, morphological changes, and/or cohesive enamel strength. The findings of this review suggest that the addition of minerals to bleaching gels can contribute to the reduction of most adverse effects, mainly sensitivity, without affecting treatment efficiency.
