| Abstract | ||||
| Objective: The purpose of this research was to evaluate how fiber-reinforced resin composite restorations perform in comparison to bulk-fill resin composite restorations in molars that underwent endodontic treatment over a duration of two years. Methods: A total of 240 individuals who had undergone treatment for mandibular molars with moderate structural loss were randomly divided into two groups, each consisting of 120 participants. One group was given polyethylene fiber-reinforced bulk-fill composite restorations, while the other group was administered standard bulk-fill resin composite restorations. The restorations were executed following the standard procedures recommended by the manufacturers. Evaluators, who were blinded to the group assignments, used modified USPHS criteria to evaluate the results at the beginning of the study, and again at six, twelve, and twenty-four months. Statistical evaluation: included the Mann-Whitney U test, Friedman’s test, and the Nemenyi post hoc analysis. The evaluation was conducted with R software , setting the significance level at p<0.05. Outcomes: No significant differences were observed between the groups during the course of the study. Conclusion: Both restoration methods demonstrated acceptable clinical performance over two years, suggesting that either could be viable options for treating molars with moderate structural loss post-endodontic therapy. Clinical relevance: Bulk-fill composites appear to be a promising approach for endodontically treated molars within this context. | ||||
