Aim: is to evaluate the regional push-out bond strength of a fiber-reinforced post system, using two resin cements.
Materials and Methods: 20 maxillary central incisors were decoronated and the roots were endodontically treated. Following post space preparation, the roots were divided into two groups of 10 specimens each. Fiber-reinforced composite posts were cemented with two resin cement systems: (a) Self-etch system (RelyX U100, Gcem, Speed Cem) and (b) conventional system (Multilink N resin cement). Three slices of each root, with a thickness of 3 mm, were prepared. The push-out test was performed with a universal testing machine at a crosshead speed of 1 mm/ minute, and bond strength values were calculated. The data were analyzed with a two-way Analysis of variance (ANOVA) and Scheffe tests (a=.05).
Results: There were no significant differences between the mean push-out bond strengths of two experimental groups but there were significant differences between the mean push out bond strengths of the root dentin regions (P<0.001).
Conclusion: Under the conditions of this study, there was no significant difference between the mean push out bond strength of self-etching and the conventional resin cement systems
