The Success of Post-Endodontic Restorations Using Different Restorative Materials in a Two Years of Follow-up

Introduction: Coronal restoration following endodontic therapy is critical for success. Restorations after endodontic treatment should minimize fractures of residual hard tissues, and leaks, and maintain dental function. The aim of this study was to evaluate the success of post-endodontic restorations using various restorative materials over a two-year period. Methods: The study involved 60 individuals aged 18 to 40. The patients were randomly divided into three groups. Conventional composite restorations were used to restore the first group. The second group was treated with a fiber-reinforced composite covered in composite resin. The third group was reconstructed using endocrowns. The restorations were prospectively investigated for two years. Results: In the composite restoration group, two restorations and one tooth were fractured, with two polishable surfaces found on one restoration surface. In the fiber-reinforced resin-supported composite restoration group, one restoration fragmented and one polishable surface was found. In the endocrown restoration group, 2 endocrowns had decementation. No significant difference was observed in periodontal examination including gingival pocket depth, plaque index and bleeding index assessment (p> 0.05). There were no marginal discrepancies and no caries in any of the restorations. At the last appointment, patient satisfaction was evaluated aesthetically and functionally using a visual analog scale. Conclusion: All groups had a 100% survival rate over the two-year follow-up period. According to the patients, there was no functional difference between the restoration groups (p> 0.05); however, aesthetically, restorations with endocrowns were more successful (p
