Endodontic treatment , method of cement application , and post pretreatment are factors that might significantly affect the retention of glass-fiber posts  into root canals mainly when cemented with regular resin cement .
Self-adhesive resin cements were found to be less technique-sensitive to luting procedures as compared with regular resin cements
This study aim ed to identify factors that can affect the retention of glass fiber posts to intra-radicular dentin based on in vitro studies that compared the bond strength ( BS ) of GFPs cemented with resin cements .
Effect of resin cement system and root region on the push-out bond strength of a translucent fiber post.
OBJECTIVES This study evaluated the bond strength of luting systems for bonding glass fiber posts to root canal dentin . The hypothesis tested was that there are no differences in bond strength of glass fiber posts luted with different cement systems . METHODS Forty bovine incisors were r and omly assigned to five different resin cement groups ( n=8 ) . After endodontic treatment and crown removal , translucent glass fiber posts were bonded into the root canal using five different luting protocol s ( self-cured cement and etch- and -rinse adhesive system ; dual-cured cement and etch- and -rinse adhesive system ; self-cured cement and self-etch adhesive system ; dual-cured cement and self-etch adhesive system ; and dual-cured self-adhesive cement ) . Push-out bond strength was evaluated at three different radicular levels : cervical , middle , and apical . The interface between resinous cement and the post was observed using a stereoscopic microscope . RESULTS Analysis of variance showed a statistically significant difference among the cements ( p<0.05 ) and the root canal thirds ( p<0.05 ) . The self-adhesive resinous cement had lower values of retention . CONCLUSIONS The resin cements used with etch- and -rinse and self-etch adhesive systems seem to be adequate for glass fiber post cementation
