Evaluation of Root Canal Filling in Primary Teeth by Volumetric Analysis: In Vitro Study

Abstract

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.

Microcomputed Tomographic Assessment of the Single Cone Root Canal Fillings Performed by Undergraduate Student, Postgraduate Student and Specialist Endodontist

“…High-quality hermetical sealing of the root canal system prevents the obturated root canals from recontamination and penetration of microorganisms and their metabolites into periapical tissues [ 4 ]. It has been shown that the homogeneity of the filling is directly related to the voids and pores inside the material [ 5 ]. Therefore, the porosity of the material can be used as one of the objective criteria for assessing the quality of the root canal obturation.…”

Tratamento endodôntico de dentes decíduos com a Pasta Guedes sem o antibiótico: ensaio clínico randomizado de não inferioridade

“…A qualidade da obturação também é descrita como fator importante para o sucesso do tratamento endodôntico, um bom preenchimento dos condutos permite a ação do material em áreas de difícil acesso através da instrumentação (Bresolin, 2017). Neste estudo, utilizou-se para aplicação do material de preenchimento do conduto a associação de técnicas, sendo aplicado com a seringa do produto e ponta específica (Angelus) e complementado com limas manuais e propulsor lêntulo em baixa rotação, uma vez que a combinação de técnicas tem demonstrado melhores preenchimentos em estudos recentes (Sijeria et al, 2018). Como resultado obtivemos preenchimento adequado, dentro dos limites apicais, mas também ocorreram preenchimento aquém do ápice e extravasamento de material (tabela 5.5).…”

“…Em relação ao material de preenchimento, além da necessidade das propriedades antibacterianas já relatadas, o preenchimento completo e uniforme dos canais radiculares têm sido apontados como fatores fundamentais para o sucesso da terapia endodôntica . Ao comparar a qualidade de preenchimento das técnicas mais utilizadas para aplicação de material obturador em dentes decíduos, a melhor porcentagem de volume obturado e número máximo de canais otimamente preenchidos foi obtido com a combinação do uso de lêntulo em baixa rotação e o sistema NaviTip, embora espaços vazios foram encontrados em todos as técnicas (Sijeria et al, 2018).…”
