Abstract
Purpose: The purpose of this study was to evaluate the flexural strength of indirect composite resins with differentpolymerization conditions. Methods: Ten specimens (2 2 25 ) of each composite resins (Tescera (T), Gradia (S) and Sinfony (S)) were fabricated by two polymerization
Methods: manufacturers’s and light heat pressure. Composite resinspolymerized by manufacturers’s method and light heat pressure served as control (TS, GS and SS) andexperimental groups (TE, GE and SE), respectively. The composite resins were tested for flexural strength and thesurface of composite resins were observed with scanning electron microscope (SEM) under X1,000 magnification.
Results: The flexural strength values of cured composite resin decreased in the following order: TE (195.4 ), TS(179.8 ), GE (169.9 ), SE (137.7 ), SS (111.1 ) and GS (100.9 ) groups.
Conclusion: The flexural strength values between the control and the experimental groups were not significantlydifferent although experimental groups showed higher flexural strength values than control groups.
