Comparative Evaluation of Flexural Strength of Two Newer Composite Resin Materials: An in Vitro Study

Objective:  To evaluate in vitro the flexural strength of two newer composite resin materials .  Material and Methods:  Twenty-four samples were equally divided into groups: G1 - Brilliant EverGlow G2: NG. The rectangular blocks 25 mm length, 2 width thickness prepared from materials. Blocks created by applying composites to a customized split mold formed between parallel glass plates. Before light-curing, covered with Mylar strips rinsed for 10 seconds water. Subsequently, they stored distilled water 24 hours at 37oC 100% humidity before testing. Each sample was placed within suitable framework aluminum. length gap support 21 speed crosshead 1 mm/minute. data subjected an independent t-test. level significance set p <0.05.  Results:  A less observed (77.43 Mpa) compared G2 (118.70 (p<0.001).  Conclusion:  Universal nanohybrid material found have greater than universal submicron hybrid material.
