Background and Objective: This study aimed to compare the push-out bond strength of fiber posts cemented with three different types of cements: glass ionomer, self-etch resin, and self-adhesive resin cement. The objective was to identify which cement provides the most effective bonding in different sections of the root canal. Methods: Thirty extracted central teeth were prepared and divided into three groups, each receiving a different type of cement. The roots underwent standard preparation, including trimming, manual and mechanical filing, and chemical treatment. The push-out test was employed to measure the bond strength of the fiber posts in the coronal, middle, and apical sections of the root canal. Results: The study revealed that in the coronal section, there were no significant differences among the groups. However, in the middle and apical sections, both the self-adhesive and self-etch groups demonstrated a statistically significant increase in bond strength compared to the glass ionomer group. Conclusion: The findings suggest that the choice of cement significantly affects bond strength, particularly in the coronal section of the root canal. Self-adhesive resin cements emerge as a preferred option due to their higher bond strength. This study provides crucial insights for dental practitioners in selecting appropriate cements for different root canal sections, enhancing the longevity and effectiveness of dental restorations.
