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

自蚀刻底漆粘接在牙本质表面时，在杂化层下方出现了约1微米宽的耐酸碱区。然而，通过使用含氟溶液，可以产生更厚、更透明的abrz。受龋病影响的牙本质上，由于表面脱矿，ABRZ的厚度比正常牙本质厚。但受龋病影响的牙本质上的抗拉结合强度低于正常牙本质上的抗拉结合强度，因此abz的质量可能较弱。然后，如果用于治疗超敏症的含氟溶液能在表面形成一层透明层，而含有的其他离子可能会在表面产生良好的效果。

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.
