Abstract The aim of this study was to assess the clinical performance of three direct composite resins and two indirect inlay systems in posterior teeth using the modified USPHS criteria. A total of 100 restorations were placed in the molars of 54 patients by one operator. All restorations were directly evaluated by two examiners at baseline, 6 months, and 12 months. Statistical analysis was conducted using McNemar chi-square test at a significance level of 5\% (p<0.05). Recall rate was 100\% at 6 and 12 months, and all the restorations evaluated (i.e., 100\%) received Alpha rating for the criteria of retention and gingival adaptation. At 12 months for the surface texture criterion, 80\% of Filtek Supreme XT received Alpha rating while it was 95\% for Tetric EvoCeram and AELITE Aesthetic. For marginal discoloration, 85\% of Tescera ATL and Filtek Supreme XT received Alpha rating while it was 95\% for Tetric EvoCeram and AELITE Aesthetic. Further, none of the restorative systems received a Charlie rating for any of the criteria at all evaluation periods. In summary, all the restorations demonstrated clinically satisfactory performance with no significant differences detected among them.
