Abstract

Objectives: The aim of this study was to evaluate the clinical performance of two bulk-fill composite resins in Class II cavities for up to twenty-four months. Materials and Methods: In total 75 Class II restorations were made in 25 patients using two nanohybrid bulk-fill resin composites and a microhybrid composite. The restorations were evaluated at baseline and at 6, 12, and 24 months, using U.S. Public Health Service (USPHS) criteria. The restoration groups were compared using the Pearson chi-square test, and the Cochran Q-test was used to compare the changes across different time points within restorative materials (p<0.05). Results: Two patients who did not attend the appointments were excluded from the study, so 23 patients were evaluated with a 92% recall
rate; at the end of the two-year follow-up, 66 restorations were evaluated. Three restorations underwent endodontic treatment and were deemed failures. The overall success rate was 96%. There were statistically significant differences between the three restorative resins in terms of color match parameter (p<0.05). No differences were observed between the restorative resins in terms of other criteria (p>0.05). Conclusions: During the two-year follow-up period, the three composite resins showed similar clinical performance except for the color match parameter.
