Abstract

Introduction: Dislodging from the root canals is the most common failure of bonded fiber restorations. Self-adhesive system has the advantage of reduced cementation procedure. The aim of this study was to evaluate the bond strengths of fiber posts with three different self-adhesive/resin systems to coronal and apical thirds of the post space dentine Materials and methods: Thirty freshly extracted single-root human teeth were selected for this study. The specimens were then randomly divided into 3 subgroups each containing 10 samples. Fiber posts (RelyX, 3M, ESPE, UK) were inserted into canals using RelyX Unicem 3M ESPE, St. Paul, MN, USA), G-Cem (GC Corporation, Tokyo, Japan) and Maxcem Elite (Kerr Hawe Neos Orange,CA, USA) adhesives. Two disc shaped sections perpendicular to the long axis of each root sample were obtained for push-out tests. Failure load value was recorded. Statistical analysis was performed using One-way ANOVA and KruskallWallis tests. Results: RelyX Unicem exhibited the highest mean push-out bond strength values at the coronal section of all samples. G-Cem exhibited higher push-out bond strength values at apical section The overall bonding data of RelyX Unicem was also observed to be the highest among groups. Conclusion: Self-adhesive systems are of practical ways of intra-canal cementation. It does not require multiple steps for success. All the systems offered acceptable retention ability.
