AbstractOBJECTIVES: There are currently some concerns on bis-phenol-A-glycidyl methacrylate(bis-GMA) as a component in dental biomaterials. This study aims at investigating Vicker’s hardness, flexural properties and water sorption of experimental fiber-reinforced composites(FRC) with a newly developed urethane dimethacrylate(UEDMA)-based resin matrix. METHODS: Three experimental light-curable E-glass fiber reinforced groups(Exper1, Exper2, Exper3; n=18) with different UEDMA contents in the resin matrix were prepared. The control group had a bis-GMA-based resin matrix(n=18). After preparation and light curing, the specimens were stored in dry condition for 24h or in deionized water at 37C for 1 and 3months. Water sorption, Vicker’s hardness together with flexural modulus and strength in 3-point bending(n=6) were investigated at each storage point. To evaluate the fracture type, scanning electron …
