چکیده

Objectives: the purpose of this in-vitro study was to evaluate the effect of 3-different post-space on the bond strength of fiber post. study design: fifty-four extracted human maxillary incisors were selected and their roots were treated endodontically. the roots were prepared according to different post spaces (torpan drill iso 100(d100), 120(d120) and enapost drill iso 140(d140), and divided into three groups. snowposts were used, and the posts were cemented with three different dual polymerized resin luting agents: panavia f, nx3 and rely x. the specimens were subjected to a pullout test using a universal testing machine at a cross-head speed of 0.5 mm/min. the maximum force required to dislodge each post was recorded. data were analyzed using the two way anova and tukey multiple comparisons tests. results: according to the results of tukey test, the bond strength values of the panavia f luting cements was significantly higher in d120 post space; otherwise, there were no significant differences between rely x and nx 3. conclusions: it had been seen that cement thickness affects the pullout strengths of fiber-reinforced posts.
