A comparative evaluation of the sealing ability of 2 root-end filling materials: an in vitro leakage study using Enterococcus faecalis

Objective. The purpose of this study was to evaluate the sealing ability of EndoSequence Bioceramic Root-end Repair (BCRR) material when compared with white mineral trioxide aggregate (WMTA). Study design. Forty single-rooted teeth were instrumented, obturated with gutta-percha, root-end resected, and retrofilled with 2 different materials: white ProRoot MTA (WMTA) (n = 15) and BCRR (n = 15). Unfilled specimens (n = 10) received no retrofill and were used as controls. All groups received E. faecalis in a created reservoir coronal to the root filling and the presence of microleakage was evaluated by counting the colony-forming units from each specimen. The results were analyzed with 1-way analysis of variance. Results. There was no significant difference in leakage between the 2 experimental groups, but there was a significant difference with the control (P <=.05). Conclusions. This study suggests that BCRR is equivalent in sealing ability to WMTA when used as root-end filling material in vitro. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2011; 112: e74-e77)
