Aim: To compare the effectiveness of conventional and game-based teaching on the level of knowledge and practice regarding oral hygiene among 7 to 10-year-old school children.Materials and methods: A total of 60 children aged 8 to 10 years were randomly divided into two groups: groups A and B. The intervention was started after the pretest evaluation of their knowledge regarding oral health and estimation of Debris Index-simplified (DI-S). Children in group A were given oral health education through flash cards once daily for 7 days. Children in group B were educated through the play-way method, i.e. connect the dots game combined with flash cards. The evaluations, regarding oral hygiene and DI-S were recorded on the 8th day after intervention. A follow-up score was also recorded after 1 and 3 months. Statistical analysis was done using paired t-test and Chi-square test.Results: There was significant increase in oral hygiene scores and decrease in debris scores compared to baseline in both groups at 1 week and 1 month. At 3 months interval, both groups showed a decrease in oral hygiene scores from baseline with group B showing highly significant reduction. The mean increase in knowledge score was also significantly better in group B (p < 0.05).Conclusion: The connect the dots game that includes oral health guidelines including good dental hygiene and dietary habits can thus be an effective intervention aid for teaching the basic oral health concepts among school going children.How to cite this article: Kumar Y, Asokan S, John B, Gopalan T.

Background: Successful obturation in the primary teeth demands complete dryness of the root canal system.Aim: The purpose of this study was to determine the effect of 95% ethanol as the final irrigant before root canal obturation in primary teeth.Materials and methods: A total of 20 extracted primary mandibular canines were biomechanically prepared and pre-obturated volume of each tooth was assessed using spiral computed tomography (CT). The specimens were divided into two groups (n = 10): group 1, Metapex group; group 2, zinc oxide eugenol group. Each group was further divided randomly into two subgroups (n = 5): subgroup 1, canals were dried with 95% ethanol; subgroup 2, canals were blot dried with paper points with the last one appearing dry. All canals were obturated and the postobturated volume of each tooth was measured. The percentage of obturated volume (POV) was calculated using the formula: (postobturated volume/preobturated volume) × 100. The POV between the groups was statistically analyzed using Mann-Whitney test and Wilcoxon Signed rank test appropriately.Results: Root canals that were dried with ethanol showed better obturation than using paper points alone and the difference was statistically significant in both group 1 (p < 0.001) and group 2 (p < 0.002).Conclusion: Drying of the root canal system with 95% ethanol can result in better obturation in the primary teeth.How to cite this article: Thiruvenkadam G, Asokan S, John B, Geetha Priya PR.
