RESUMEN
BACKGROUND: The depression, anxiety, and stress is a major educational problem among students all around the world. The purposes of this study were to determine the depression, anxiety, and stress among the high school adolescent children in public and private schools in Rangareddy district, Telangana state. MATERIALS AND METHODS: The present study was a cross-sectional study. The study sample considered 120 children from private schools and 259 children from public schools were studied. The study tool used was a questionnaire containing DASS (Depression, Anxiety, and Stress scale and sociodemographic characteristics. The data were expressed as proportion and mean values (Analysis of variance, independed t-test, and Pearson correlation) spatially tests were used at a significance level of P < 0.05). RESULTS: The overall prevalence of depression in children from the public school was found to be only 5%, that of anxiety was 20.8%, and that of stress was 15.8%; the overall prevalence of depression in children from private schools was found to be 1.9%, that of anxiety was 20.5%, and that of stress was 20.1%. CONCLUSION: In both schools, anxiety and atress were found to be more among study participants. Depression was observed to be less. But if they have more anxiety and stress and if not taken proper care at this point of time, it might get converted into a state of Depression.
RESUMEN
BACKGROUND: The use of resin-modified glass Ionomer cement in sandwich technique is widely practiced with the advent of various newer generation of composites the bond between resin-modified glass Ionomer and these resins should be validated. This study is done to evaluate the interfacial microgaps between different types of liners and dentin, liners and composite (Filtek p60 [FLp60]) using scanning electron microscope (SEM). MATERIALS AND METHODS: Standardized Class V preparations were performed in buccal/lingual surfaces of 30 caries, crack and defect-free extracted human third molars. The prepared teeth were divided into three groups. Group I: Single bond (SB), Group II: SB + synergy flow, Group III: SB + vitrebond. They were restored with composite resin FLp60, according to the manufacturer instructions. The SB + vitrebond, cross-sectioned through the canter of the restoration. The specimens were fixed, dehydrated, polished, and processed for SEM. The internal adaptation of the materials to the axial wall was analyzed under SEM with ×1000 magnification. RESULTS: The data obtained were analyzed with nonparametric tests (Kruskal-Wallis, P < 0.05). flowable composite or resin-modified glass ionomer applied in conjunction with adhesive resulted in statistically wider microgaps than occurred when the dentin was only hybridized prior to the restoration. CONCLUSION: Hybridization of dentin only provides superior sealing of the dentin-restoration interface than does flowable resin or resin-modified glass ionomer.
RESUMEN
INTRODUCTION: Remineralization as a treatment procedure has received a lot of attention both from clinicians as well as researchers. The objective of this study was to assess the effect of Remin Pro® on enamel microhardness after bleaching the teeth with McInnes bleaching agent using Vickers microhardness tester. MATERIALS AND METHODS: In this study, freshly extracted ten central incisors were taken which were subjected to baseline indentation by using Vickers microhardness indenter and then McInnes bleaching solution was applied for 5 min to demineralize these teeth. Remin Pro a newer remineralizing agent was applied for 7 days, which showed an increase in microhardness at the end of 7 days. RESULTS: The values were subjected for statistical analysis using paired t-test. All the samples showed a decrease in the microhardness after bleaching with McInnes solution. The decrease in mean hardness from baseline to demineralization was found to be statistically significant (P < 0.001). However, remineralizing the same tooth with Remin Pro for 7 days, showed an increase in hardness, which was found to be statistically significant (P < 0.05). CONCLUSION: McInnes bleaching agent decreases the microhardness of enamel and Remin Pro® used in the study causes an increase in the microhardness of bleached enamel.
