After root filling, post space preparations were done. Five main groups were sub-divided into 3 groups (self-etch, etch-and-rinse, and self-adhesive) corresponding to the resin systems applied. After post cementation, 3 slices were obtained from different regions (coronal, middle, apical) for push-out testing. SEM images of specimens were obtained to evaluate for debonding failures. Differences in bond strength were evaluated by ANOVA and Post-hoc Tukey HSD methods. </p> <p> <strong>Results: </strong> It was observed that in Tubli-Seal, BC Sealer and Sealapex groups the bond strength was significantly decreased ( <em>p </em>< 0.01). No significant difference (p > 0.05) in bond strength values was observed between the AH Plus and control groups. It was also observed that the bond strength values were similar (p >0.05) in different resin cement systems. </p> <p> <strong>Conclusion: </strong> Root canal sealers affect bond strength between fiber posts and the root canal dentin, whereas different resin cement systems have no effect on the bond strengths. </p> <strong>Keywords: </strong> Bond strength; fiber post; push-out; resin cement; root canal sealer}, number={3}, publisher={Ataturk University}
