The introduction of modified bioceramic calcium silicate- based materials into clinical practice has changed the standards and strategies of endodontic treatment. The review article highlights modern calcium silicate- based cements that are used in various areas of endodontics, including vital pulp therapy, root canal obturation, management of endodontic complications and pulp regeneration. The classifications of bioceramic materials based on their chemistry and specific use in endodontics are presented. The physicochemical and biological properties of various types of materials, as well as the features of their clinical application, are described.

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%.
