 Purpose: The present study evaluated fiber post bond strength in root dentin using various root canal sealers and resin cements.

Material and Methods: After root canal preparation, teeth were divided into 5 distinct groups [(Sealapex (calcium hydroxide-based); AH Plus (resin-based); Tubli-Seal (eugenol-based); BC Sealer (bioceramic-based) and No Sealer (control)] according to root canal sealer used. 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.

Results: It was observed that in Tubli-Seal, BC Sealer and Sealapex groups the bond strength was significantly decreased (p < 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.

Conclusion: 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.
