Microleakage Comparative Evaluation of RMGIC and Alkasite with and without Adhesive System in Class V Cavity: An In Vitro Study.

AIM AND OBJECTIVE: This study aimed to compare microleakage of resin-modified glass ionomer cement (RMGIC) and alkasite with and without adhesive system in class V cavity. MATERIALS AND METHODS: Thirty class V cavities were prepared on the buccal surface. All prepared samples were randomly divided into three groups. Group I was restored with RMGIC, group II was restored with Cention N after the application of adhesive system, and group III was restored with alkasite. Samples were subjected to 200 thermocycles between temperature baths at 5ºC and 55ºC. Samples were stained with 2% methylene blue. The teeth were sectioned longitudinally, and the sections were then observed under stereomicroscope at a magnification of 20×. RESULTS: Statistical analysis showed that there was less microleakage in Cention N using adhesive system in both occlusal margin and gingival margin. CONCLUSION: There were significant differences between RMGIC, alkasite with adhesive system, and alkasite without adhesive system in class V cavity. Least microleakage at the occlusal margin and gingival margin was seen with Cention N using adhesive system and highest microleakage at the RMGIC. CLINICAL SIGNIFICANCE: Cention N using the adhesive system affects the microleakage in the class V restoration. The study theorizes that the material restorations showed less microleakage in the occlusal margin than in the gingival margin.

Risk Factors of Dental Caries: Consumption of Sugary Snacks Among Indonesian Adolescents

Objective: To determine the risk factors of caries among adolescents in Padang City, by assessing the frequency of sugary snack consumption. Material and Methods: A cross-sectional study was conducted on 150 randomly selected junior high school students using a selfadministered questionnaire along with oral examinations. The questionnaire consisted of questions on socio-demographic characteristics, oral health behavior, and frequency of consumption of sugary foods. Data were analyzed using the Chi-square tests and multivariate analysis. Results: Dental caries was found in 61% of the total students and was more prevalent in males when compared with females. The mean DMFT score was 1.3±1.4. Sugary snack consumption, attitude, and protective factors were significantly related to the occurrence of caries (p<0.001). The risk of dental caries in subjects with high amounts of sugary snack consumption was 5.67 times higher (OR=5.7; CI: 2.7-11.9) than those with low consumption. Subjects with low protective factors, high consumption of sugary foods and drinks, and bad attitude presented with a caries prevalence of 94%. Conclusion: The consumption of sugary foods was found to play an important role in the development of caries in the current study.
