Effects of antioxidants on DNA-double strand breaks in human gingival fibroblasts exposed to methacrylate based monomers

Nov 25, 2017 by in Dental Materials Comments Off on Effects of antioxidants on DNA-double strand breaks in human gingival fibroblasts exposed to methacrylate based monomers

Abstract Objective (Co)monomers from dental resin composites have cytotoxic and genotoxic potential. In previous studies it has been demonstrated that antioxidants can decrease the cytotoxicity of various dental (co)monomers. In…
