Modification of closite by glycidyl methacrylate and its effect on mechanical properties of flowable dental composites

Dental composites as dental restorative materials have weak mechanical and physical properties in stressful areas.1,2,3 In this study, the closite surface modified with glycidyl methacrylate and investigated by IR spectroscopy and XRD analysis. Then, the modified closite was applied as a filler for preparation of flowable dental composites (Tetric Flow, Invoclar,Vivadent, USA) in different weight percent 0, 0.2, 0.5, 1, 2.5, 5 and 7.5 wt% at room temperature. Afterward, the physical and mechanical properties of prepared dental composites such as flexural strength, flexural modulus were investigated. Results shown that the modified closite by glycidyl methacrylate can improved strength and flexural modulus in flowable dental composites
