This study tested the hypothesis that hybridization of intraradicular dentin eliminates interfacial gaps, thereby improving the coronal seal and retention of teeth restored with fiber posts. Post spaces were bonded with two types of fiber posts, usingthe corresponding etch-and-rinse adhesives and dual-cured resin cements. Longitudinal sections of the interfaces were examined for dentin hybridization in the coronal- and middle thirds of the root canals. Resin replicas of these sections were evaluated for interfacial gap formation. Although intraradicualr dentin hybridization was not compromised irrespective of whether the adhesives were light-cured before cementation, the universal occurence of interfacial gaps along the hybrid layer surface or the post-cement interface reflects the challenge in bonding to postspaces with low compliance and high C-factors. The clinical success associated with bonded fiber posts is probably due to predominantly to frictional retention.
