Abstract

This study evaluates the fracture resistance of short-fiber reinforced composite and elastic fiber posts compared to conventional hybrid composites in reinforcing peri-cervical dentin of endodontically treated teeth. Methods: The crowns of thirty single-canal mandibular premolars were resected to achieve a dimension of 4mm from 1mm below the highest point of the proximal cervical line. In Group 1, teeth underwent endodontic treatment with gutta-percha filled up to the cement-enamel junction (CEJ) and restored with conventional hybrid composite. Groups 2 and 3 involved obturation up to 5 mm below the CEJ and restoration with short fiber-reinforced composite and elastic fiber posts, respectively. Fracture resistance was evaluated using a Universal testing machine. Statistical Analysis: The collected data were tabulated and assessed using one-way analysis of variance (ANOVA), and Tukey’s post hoc test for pair-wise comparisons. Results: The short fiber-reinforced composite resin exhibited a significantly higher mean fracture resistance compared to other groups. The mean fracture resistance values (in newtons) were Group 2 (1238.07± 64.09 N) > Group 3 (988.12 ± 78.51 N)> Group 1(553.838 ± 78.76 N), with results between each group being statistically significant (P < 0.05).Conclusion: Within the limitations of this study, reinforcing PCD with a short fiber-reinforced composite significantly increased fracture resistance compared to using an elastic fiber post and conventional hybrid composite resin.

Keywords: Conventional hybrid composite, elastic fiber post, fracture resistance, peri-cervical dentin, short fiber-reinforced composite.
