Abstract :Aim: This study compares the push-out bond strengths of 3 different fiber post systems bonded with resin cement to root canal dentin. Material and Methods: The study used 15 extracted single-rooted mandibular canine teeth. After the endodontic treatment of the teeth, they were randomly divided into three groups to apply different post-systems(n=5). Reforpost glass-fiber, Polydentia glass-fiber, and AAA Transparent fiber post systems were used in this study. The posts have adhered to the root canal with Panavia F2.0. A total of 6 slices of 1 mm thickness in the transversal direction were obtained, two from each of the coronal, middle, and apical sections of the prepared samples. The push-out test was performed from apical to coronal at a 0.5 mm/min speed. ANOVA and Tukey HSD tests were used for statistical analysis(p<0.05). Results: The highest push-out binding values were observed in the Polydentia(5.04±0.54); the lowest was seen in the Reforpost(1.5±1.03). There was no statistical difference between the push-out binding values of the samples\' apical, middle, and coronal regions for the Reforpost and Transparent groups. In the Polydentia group, the push-out binding values of the coronal region samples were significantly higher than those in the middle region. When the post groups were compared, the difference between the push-out binding values of all groups was statistically significant. Conclusion: The surface properties of the posts can affect the push-out bonding values. Polydentia showed the highest push-out binding values. In addition, the push-out attachment values of the posts may vary in different root canal regions.
