The morphological difference between dentin powder surfaces before and after adsorption could not be determined. After heating, however, dentin powder which adsorbed HEMA was more resistant to demineralization with 6NHCI than the powder which did not adsorb. SEM examinations demonstrated that there was a demineralization-resistant dentin layer in tooth which adsorbed HEMA. The results indicated that HEMA infiltrated into intertubular dentin during adsorption.\n}, pages = {11--16}, title = {メタクリル酸2-ヒドロキシエチルの象牙質への吸着 : 接着促進効果との関係}, volume = {4}, year = {1999} }
