Evaluation of biomechanical properties of root canal sealers

Why is it important?

The greater push-out bond strength and the best adhesive pattern were shown by BioRoot RCS, a bioceramic sealer, compared to other tested materials. These results are attributed to the property of bio-ceramic sealer capable of forming micromechanical bonds with the root dentin and providing better adhesion. On the other hand, One-Fil exhibited the highest dentinal tubule penetration compared to other groups. AH Plus (epoxy resin-based sealer) used in the present study revealed greater dentinal tubule penetration than BioRoot RCS but less than other calcium silicate sealers. However, the push-out bond strength and adhesive patterns were less than those of BioRoot RCS.
