BACKGROUND/PURPOSE: A perfect sealing of root canal system is essential for preventing ingress of bacteria from the oral environment. The purpose of this study was to evaluate the apical sealing ability of bioceramic (EndoSequence BC Sealer®) and epoxy resin-based (AH Plus®) sealers at 24 h, 7 days and 4 weeks. MATERIALS AND METHODS: < 0.05 was considered statistically significant. SEM showed EndoSequence BC Sealer® had better penetration into dentinal tubules. CONCLUSION: Bioceramic sealer could promote proper sealing of root canals obturated with multiple wave condensation.
