Objective: To evaluate the clinical efficacy of two flowable composite resins used to restore occlusal caries lesions. Tetric Flow (Vivadent) and Esthet-X Flow (Dentsply/Caulk) are composite resins with decreased filler loading (Tetric Flow: 67% filler by weight, 43% by volume; Esthet-X Flow: 61% filler by weight, 53% by volume) and lower viscosity compared to conventional composite resins.
Method And Materials: Sixty-three teeth with occlusal caries were randomly assigned to calibrated practitioners who placed occlusal restorations (32 for Esthet-X Flow; 31 for Tetric Flow).
