200031136.hwp - Abstract - INFLUENCES OF BISGMA AND TEGDMA RATIO ON THE RELEASED COMPONENTS OF EXPERIMENTAL COMPOSITE RESINS Hyun-Jung Moon, M.S., M.S.D. Dept. of Dental Biomaterials, Graduate School, Seoul National University. (Directed by Prof. Cheol-We Kim, D.D.S., M.S.D., Ph.D.) The properties and the performance of composite resin are dependent on the resin matrix comprising monomer system, initiator system and stabilizer, the inorganic filler and the coupling agent of the materials. Changes in composition, and chemistry of the constituent monomers, treatment of filler and light sources can affect the properties of the materials. The commonly used monomer systems of dental composite resins are 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl]propane (BisGMA) and its deri- vatives. They have been widely used because of their acceptable chemical, mechanical, esthetic properties despite of the polymerization shrinkage and the insufficient poly- merization with high residual double bonds. It is not clear whether released com- ponents due to insufficient polymerization penetrate into the human blood system. Measurement of released components using a high-performance liquid chromatography (HPLC) is more sensitive than physical and mechanical tests to detect the changes in characteristics of composite resin. Identification and quantitative analysis of released components using a HPLC should be considered as an efficient method for assessing the biocompatibility when composite resin are made for specific application. The purpose of this study was to evaluate the effects of varying BisGMA and triethylene glycol dimethacrylate (TEGDMA) ratio, silane treatment of filler and light sources on the released components of experimental composite resins. Ten kinds of experimental composite resins (ECRs) with five set of different BisGMA:TEGDMA ratio (70:30, 60:40, 50:50, 40:60, 30:70) were made incorporating the silane treated filler or non-treated fillers.
