Background: Comparison of the compressive strengths of three bulk-fill composites (Sonic Fill, FiltekBulk-fill, and Tetric N Ceram) with a universal hybrid composite (Swiss Tec). Materials and Methods: Three high viscosity bulk-fill composites were compared with a universal hybrid composite. The specimens were prepared for each group using a cylindrical plastic split mould with dimension 6mm in height and 4 mm in diameter and light-cured for 20 seconds followed by 24 hr water storage. The compressive strengths were measured by subjecting each specimen to a load of 1 mm/min under a universal testing machine (UTM). Results: Comparison of compressive strengths of four groups was made using one-way Analysis of Variance (ANOVA) followed by post hoc Tukey's test for multiple comparisons. The analysis showed that Sonic fill showed the greatest compressive strength followed by FiltekBulk-fill and Tetric N Ceram. The universal hybrid composite Swiss Tec exhibited the least compressive strength. Conclusion: Bulk-fill composites exhibited better compressive strength.
