【 摘 要 】

Aims:  The aim of the present study was to evaluate and compare the push-out bond strength of single and multiple fiber-reinforced posts cemented with dual-cure resin cement using total-etch and self-etch adhesive systems. Methods:  Sixty single-rooted maxillary permanent incisors were decoronated and endodontically treated. Following post space preparations, the roots were divided into four groups (n = 15); Group 1: single fiber-reinforced composite post with the total-etching agent, Group 2: single fiber-reinforced composite post with the self-etching agent, Group 3: multiple pin posts with the total-etching agent, and Group 4: multiple pin posts with the self-etching agent and then cemented using dual-cure resin cement. The samples were then sectioned to obtain approximately 2-mm disks, and a push-out test was performed. Data obtained were statistically analyzed using analysis of variance, post hoc Tukey, and unpaired t-test. Results:  The mean push-out bond strength values showed that Group 3 had significantly higher bond strength as compared to the other groups (P < 0.05). Conclusions:  Dentapreg multiple pin posts with total-etching agents resulted in higher push-out bond strength as compared to single fiber-reinforced posts and self-etching agents.
