Abstract

Inadequate sealer penetration and weak adhesion to dentin remain major challenges affecting the long-term success of endodontic treatment. Therefore, it is of interest to compare the dentinal tubular penetration and shear bond strength of the tricalcium silicate based sealer BioRoot RCS with the resin-based gold standard sealer AH Plus using SEM and universal testing methods. Statistically significant differences were observed between the two sealers, with AH Plus showing greater penetration depth and higher shear bond strength values (p < 0.05). Mixed failure patterns predominated on debonded surfaces, indicating combined adhesive and cohesive modes of failure in both groups. Thus, data shows the interfacial adaptation and bonding performance of contemporary root canal sealers, thereby supporting evidence-based material selection for enhanced endodontic sealing efficacy.
