Abstract
Authors have studied on the resin restorative materials which can adhere strongly to tooth structure. During these studies, various amino acid acrylate have been synthesized, among them, N, O-dimethacryloyl tyrosine (DMTY) was most favourable. Based on this composition, a bonding system which can polymerize with redox system was prapared and applied as an bonding agent between human dentin and composite resin. In the present investigation, the effect of concentration of DMTY and the kind and amount of catalyst on the adhesive strength was studied. From the observation, such an composition as DMTM (30)-HEMA (70) mol% monomer into which both 1.0wt% of BPO and sodium benzene sulfonic acid, showed the favourable adhesive strength of 44kg/cm2 to the polished (by abrasive sand paper of JIS600) human dentin.
