| Research Abstract |
The acid-base resistant zones, which were about 1 micro meter width, were observed beneath the hybrid layer when the self-etching primer bonding systems were used onto dentin surface. However, more thicker and clear ABRZs were created by applying the fluoride containing solution.And the thickness of the ABRZ on caries affected dentin was thicker than normal dentin because of the demineralization of the surface. However the tensile bond strength onto the caries affected dentin was lower than onto the normal dentin so that the quality of the ABRZ might be weak. Then, if fluoride containing solution, which is for the treatment of hyper sensitivity, could make a clear layer and other contained ions might give the good effect on the surface.
