Abstract
Aim. This study aimed to determine the residual filling material and the reestablishment of working length and apical patency after retreatment of TotalFill® BC Sealer.
Materials and methods. Thirty maxillary incisors were used in a single cone obturation technique with TotalFill BC Sealer (FKG, Switzerland) and randomly divided into 6 groups according to the retreatment technique. The samples were scanned by micro-CT before and after retreatment in order to evaluate the residual filling material on the root dentin walls. Data were analyzed statistically with the Kruskal-Wallis tests (p < 0.05).
Results. No instrumental protocol was able to remove all obturation material from the root canals. The differences in reduction in the total volume of filling material percentage were statistically significant (p < 0.05) among groups with and without ultrasound or sound activation in retreatment protocol.
Conclusions. The most effective root canal retreatment was determined with D-Race + XP-endo Shaper + XP-Endo Finisher R + US (3.0 W) protocol; it was found that the efficiency of filling material removal was more than 92%.
