Evaluation of Microtensile Bond Strength between SMART Technique and Conventional Glass Ionomer Cement-treated Carious Primary Dentin.

Background: Silver diamine fluoride (SDF) solution has been used clinically to prevent and arrest dental caries. To evaluate the microtensile bond strength between silver-modified atraumatic restorative technique (SMART) and glass ionomer cement (GIC) applied to carious primary teeth and also the mode of restoration failure. Materials and methods: A total of 40 carious primary molars were equally allocated into test and control groups after sectioning through the middle of the carious lesion. The test specimens were treated with one drop of 38% SDF and the control with deionized water. The samples were stored in artificial saliva for 14 days at 37° C and the dentin surfaces were conditioned and restored with Fuji IX GP Extra. After 24 hours storage in artificial saliva, the specimens were prepared for testing of microtensile bond strength. Paired t-test was used to compare the mean bond strengths. The mode of failure was assessed with a stereomicroscope under 40× magnification. Results: The mean microtensile strength for the test group was 7.39 MPa [standard deviation (SD ± 2.3)] and 7.20 MPa (SD ± 1.98) for the control group (p > 0.05). The most common mode of failure was the mixed failure mode in both groups. Conclusion: Silver diamine fluoride (SDF) does not adversely affect the bond strength between GIC applied to carious dentin.

Enamel Erosion: A Possible Preventive Approach by Casein Phosphopeptide Amorphous Calcium Phosphate-An In Vitro Study.

CONTEXT: Several efforts were made in order to alter the compositions of acidic food items concerning their properties to be able to reduce their erosivity potential. The addition of combinations of calcium and phosphate salts to these food products has grabbed great interest. AIM: In vitro evaluation of the effect of the addition of 0.2% w/v casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) to four commonly available beverages (of which two were carbonated) on enamel erosion. MATERIALS AND METHODS: Sound-extracted human third molar teeth were taken, and enamel sections (n = 270) were made and polished. Acid-resistant nail varnish was painted to create an exposed enamel window of 1 mm2, followed by testing of the four soft drinks and distilled deionized water (DDW). Every drink was evaluated with and without the addition of 0.2% w/v CPP-ACP. The enamel specimens were kept in 50 mL solution at 37°C for 30 minutes, rinsed, and then varnish was removed. All samples were then profiled using white-light profilometer, and erosive depths were recorded. STATISTICAL ANALYSIS: One-way analysis of variance test and post hoc Tukey test. RESULTS: Enamel erosion was created by all the soft drinks tested, but the addition of 0.2% w/v CPP-ACP has remarkably reduced (p value < 0.05) erosive depths in all test solutions compared to solutions without CPP-ACP. The erosive depths for solutions with DDW did not vary much from those with 0.2% CPP-ACP. CONCLUSION: Addition of 0.2% w/v CPP-ACP to the soft drinks has remarkably reduced their erosivity potential.

Prevalence of traumatic dental injuries to the anterior teeth among three to thirteen-year-old school children of Tamilnadu.

CONTEXT: Dental trauma has become an important attribute of dental public health. The primary requisite before actively dealing with such problems is to describe the extent, distribution, and associated variables with the specific condition. AIMS: The aim of the present study was to assess the prevalence and distribution of traumatic dental injuries (TDI) to anterior teeth among 3 to 13 years old Chidambaram school children. SETTINGS AND DESIGN: A cross-sectional study was conducted. Data was collected through a survey form and clinical examination. MATERIALS AND METHODS: A total of 3200 school children in the age group of 3-13 years were selected from 10 schools of Chidambaram, Tamilnadu. Information concerning sex, age, cause of trauma, number of injured teeth, type of the teeth, lip competence, terminal plane relationship and the molar relationship were recorded. STATISTICAL ANALYSIS USED: The statistical software EPIINFO (Version 6.0) was used for statistical analysis. In the present study, P≤0.05 was considered as the level of significance. RESULTS: The trauma prevalence in the present study was 10.13%. Children with class I type 2 and mesial step molar relationship exhibited more number of dental injuries. Enamel fracture was the most common injury recorded. Only 3.37% of the children had undergone treatment. CONCLUSION: The high level of dental trauma and low percentage of children with trauma seeking treatment stresses the need for increased awareness in Chidambaram population.

Prevalence of early loss of primary teeth in 5-10-year-old school children in Chidambaram town.

INTRODUCTION: The premature loss of primary teeth may reduce arch length required for the succeeding tooth and, hence, predisposes crowding, rotation and impaction of the permanent teeth. There are only limited studies carried out about the prevalence of early loss of primary teeth. AIM: The present study was performed to evaluate the prevalence of early loss of primary teeth in school children in Chidambaram town in Tamilnadu, India. SETTINGS AND DESIGN: A total of 1121 school children (561 boys and 560 girls) between 5 and 10 years of age were selected for the study. MATERIALS AND METHODS: An experienced examiner performed all clinical examinations under natural light. Data including age and missing tooth was collected. STATISTICAL ANALYSIS USED: Microsoft Excel/2000 (Microsoft Office XP) data spreadsheet was used and later exported to the Statistical Package for Social Science (SPSS) for Windows (version 10.0). Descriptive statistics was applied and, from the results, chi-square tests were applied at a level of significance of 5% (P < 0.05). RESULTS AND CONCLUSIONS: The results showed that 16.5% of the sample had early loss of primary teeth, but no differences were observed between genders (P > 0.05). The greatest prevalence was found among the 8-year olds (5.08%), and the most commonly missing teeth were the right lower primary first molars (16.82%). It can be concluded that the prevalence of early loss was high and that the lower primary molars were the most commonly missing teeth in the present study.
