PurposeThis study was conducted to evaluate the efficacy of various techniques to fill root canals of primary teeth by volumetric analysis using cone beam computed tomography (CBCT) to assess percentage of obturated volume (POV), percentage volume of voids (PVV), and depth-of-fill.MethodologyRoot canals in 40 extracted deciduous maxillary incisors were instrumented with H-files to size 35 and volume of the canal measured using CBCT under “On Demand 3D AppTM Software” (Cybermed Inc. Medical 3D imaging software). The teeth were divided into four groups of 10 samples each and root filled by Lentulo spiral mounted on slow-speed hand-piece, NaviTip System, Bi-directional spiral and Combination method i.e. Lentulo spiral mounted on slow speed hand-piece followed by NaviTip syringe respectively, after that depth-of-fill for each group was checked. Then, the filled canal volume was measured using CBCT under “On Demand 3D AppTM Software”. Further, the (POV), (PVV) was calculated.Statistical analysisThe data were statistically analysed using one-way ANOVA, Turkey post Hoc test and Pearson’s Chi-square test.Clinical significanceAdequate adaptation of root canal filling material decreases the chance of microorganism regrowth, reinfection due to voids creation and minimizes the potential drawback of overfilling like foreign body reaction or deflection of the unerupted permanent tooth.ResultsThe four groups were comparable in canal volume. The overall percentage of obturated volume was 53%, 59.7%, 40.3% and 75.1%; the overall percentage volume of voids was 48%, 40.3%, 58.6%, 29.5%; optimally filled canals for each group was 80%, 60%, 30% and 90% respectively (p < 0.05).ConclusionThe greatest percentage of obturated volume and maximum number of optimally filled canals was obtained in method combining both Lentulo spiral in slow speed hand piece along with NaviTip system. Whereas, voids were the constant finding with all root fillings.How to cite this article: Sijeria P, Bhartia R, Swamy KVN, Kulkarni S, Singla S.

Background: To determine pediatricians' knowledge and views on promoting oral health of their patients. Materials and Methods: The present study was conducted among the pediatricians in Indore, Madhya Pradesh, India. The study was cross sectional in design. 204 pediatricians were approached for the study out of which 114 participated in the study, and the data was collected using an objective questionnaire without any oral health information.Result: The present study shows that pediatricians had poor to moderate knowledge and awareness regarding oral health issues, but they believed that they have an important role and were already participating in promoting oral health. Conclusion: Pediatricians were aware that assessment of oral health and counseling about prevention of oral disease should be included as an integral part of child care, but their knowledge on oral health issues need to be updated.
