신규 3작용성 메타크릴레이트의 치과용 광중합형 콤포짓트 레진용 단량체로서의 응용 연구 = Research on Application of A New Trifunctional Methacrylate as a Monomer For Light-Cured Dental Composite Resin

다국어 초록 (Multilingual Abstract)

Tris[4-(2-hydroxy-3-methacryloxypropoxy)phenyl]methane(THMPM) was prepared easily from triphenylolmethane triglycidyl ether in good yield. As compared with composite resin formulated with difunctional bis-GMA, the physical properties of a newly developed composite resin formulated with trifunctional THMPM was evaluated. Cytotoxicity and acute toxicity of composite resin based on trifunctional THMPM evaluated according to ISO standard method. The depth of cure of the composite resin based THMPM was higher than that of the bis-GMA composite. There were no significant differences in flexural strength and water sorption between the composites resin based on THMPM and bis-GMA. The water-solubility value for the light-activated composite resins formulated with THMPM was much lower than that for a control bis-GMA composite. According to cytotoxicity evaluation, the composite resin based on THMPM showed very mild cytotoxicity with the response index of between 0/0 and 1/0. No acute toxicity of composite resin formulated with trifunctional THMPM was also observed. It is believed that THMPM is promising candidate for application as a photocurable dental composite resin.
