Title: The Investigation of Flexural Strength Properties of Resin Composite Core Materials.
Abstract: Objective: This study was used to evaluate the flexural strength of three kinds of resin composite core materials with a method of three-point bending test. Method: The three kinds of resin composite materials, DC Flow Core, Bisfil -Core and LuxaCore, were used in this study. For each material, six rectangular specimens (the sizes 2.0×3.0×25.0) were fabricated. The flexural strength was measured on Instron Universal Testing machine at a crosshead speed of 0.5mm/min. Data were collected and analyzed by ANOVA. Results: Flexural strength of three materials as follows: DC Flow Core 137.96±9.48 MPa,Bisfil-Core 123.82±12.99 MPa,LuxaCore 110.11±10.03MPa. Flexural strength of DC Flow Core was significantly higher than Bisfil-Core( P 0.041) and LuxaCore( P 0.001), and Bisfil-Core was significantly stronger than LuxaCore( P 0.047). Conclusions: In this study, all three materials were found to meet the clinical need in terms of flexural strength. DC Flow Core had the highest flexural strength among three materials.
