In vitro evaluation of apical leakage of three bioceramic materials using glucose leakage model in a simulated open apex

Abstract

Background: Recently, new calcium silicate-based materials have been introduced as root-end filling material which offers improved color stability and handling characteristics, while exhibiting physical and chemical properties comparable with mineral trioxide aggregate (MTA). Aim: The purpose of this study was to compare the sealability of 3 calcium silicate-based materials - MTA Plus (Prevest Denpro, India), Biodentine (Septodont, St. Maurdes Fossés, France), and TotalFill BC RRM (FKG, Brasseler, Savannah, USA) in a simulated open apex model. Materials and Methods: Thirty-two recently extracted human maxillary anterior teeth with single, straight root canals were selected and after establishing the working length, canals were prepared by Protaper Gold system up to size F3. The apical end was resected at 3 mm to simulate an open apex. Prepared roots were divided into groups according to the root repair materials – MTA (Prevest Denpro, India), Totalfill Bioceramic Root Repair Material (FKG, Brasseler, Savannah, USA), and Biodentine (Septodont, St. Maurdes Fossés, France). The apical plug of the root filling material was placed in the orthograde direction and a glucose leakage model was used to study the sealability of the materials. Results: All three materials showed more leakage at 14 days than at 7 days, however, there was no statistically significant difference between them. Conclusion: All three bioceramic materials exhibited equal amounts of apical leakage at 7 and 14 days.
