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 .
Immediate and 24-hour evaluation of the interfacial strengths of fiber posts.
This study examined the contribution of testing time on the interfacial strengths of  fiber posts to radicular dentin . Twenty-five fiber posts were luted to root segments  with resin cements and a zinc phosphate cement . Immediately upon setting of the material s , the roots were sectioned into slices and r and omly divided into two subgroups , depending on testing time ( immediate vs. 24-hours ) , for push-out test . The results showed an improvement on the interfacial strength after 24 hours of storage . When data were pooled for each cement , the interfacial strengths ( MPa ) were : Optibond Solo Plus/Nexus : 10.3+/-3.8a ; zinc phosphate cement : 10.1+/-2.7a ; Multilink : 9.6+/-3.8ab ; RelyX Unicem : 7.1+/-4.9bc ; AllBond 2/Duolink : 6.7+/-3.5c ( groups with same superscript letter were not statistically significant ) . It is concluded that bond strength can increase during the first 24 hours and that the interfacial strength is predominantly contributed by frictional retention
