| Research Abstract |
The purpose of this study was to improve the bond strength of resin cement using chemical compound. Various oligopeptides which bind to type I collagen, calcium ion or hydroxyapatite were synthesized and added to resin cement or tooth-conditioning agent. Bond strengths of experimental cements were evaluated by micro-tensile method. Experimental resin cements containing chitosan oligomer or sodium fluoride were also produced and their effective performances without inhibiting the bond strength were shown.
