Abstract: AIM: To evaluate the efficiency of three solvents in achieving patency in teeth obturated using bioceramic sealer (BCS) and to assess the effect of these solvents on the root canal wall dentine. MATERIALS AND METHODS: = 7) based on the solvent used: Group I-Chloroform, group II-10% citric acid, and group III-xylene. After establishing the working length, the teeth were then instrumented and obturated using Gutta percha (GP) and BCS. Two weeks later, GP was removed, and apical patency was re-accessed with a 10-C file and the respective solvent. The time to gain patency through BC Sealer was recorded. Nine teeth (three per group) were irrigated with these solvents, and scanning electron microscopy was used to evaluate the effect of solvents on the dentin. The Kruskal-Wallis and Dunnett-Bonferroni tests were used for statistical analysis. RESULTS: = 1.000). Considering the scanning electron microscope evaluation, xylene caused a significant amount of open tubules in dentine, without any detritus and the smear layer covering the root surface when compared to 10% citric acid and chloroform. CONCLUSION: Xylene and 10% citric acid were more efficient than chloroform for dissolving the BCS. Statistically, there is no significant difference between xylene and 10% citric acid in achieving patency. Group III, in which xylene was used as the GP solvent, showed a significant amount of erosion compared to the other two groups.
