Assesment and reconstruction od the acid-base resistant zones/the creation of theSuper tooth

自酸蚀底涂层粘接牙本质表面时，在混合层下可观察到宽度约为1 μ m的耐酸碱区。而含氟溶液处理后，牙本质表面形成的ABRZ更厚、更清晰，且由于表面脱矿作用，龋蚀牙本质表面ABRZ的厚度较正常牙本质更厚。但与正常牙本质相比，龋蚀牙本质的抗张强度较低，因此ABRZ的质量可能较弱。然后，如果含氟溶液，这是用于治疗超敏感，可以使一个明确的层和其他含有离子可能会给表面上的良好效果。

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.
