Abstract

Objective: The purpose of this study was to compare the bond strength of Bio C Sealer and MTA Fillapex calcium silicate-based cements and another AH Plus epoxy resin cement. Methodology: the sealers of the study were divided into three groups to perform vertical condensation technique in the obturation of 30 inferior premolar roots, of which 5 slices of each were sectioned, to be subjected to push-out tests by means of the universal testing machine, to record the bond strength of the sealers analyzed in megapascals (MPa). Statistical analysis was done using the one-way ANOVA and Bonferroni tests. Results: it was shown that Bio C Sealer (5.30 MPa) obtained the highest adhesion strength, followed by AH Plus (3.40 MPa) and MTA Fillapex (1.39 MPa) which got the lowest bond strength with statistically significant differences between the groups. Conclusion: Bio C Sealer has greater bond strength to root canal walls.
