方法测试和比较含氟牙釉质粘接剂及不含氟牙釉质粘接剂的剪切强度以及扫描电镜下粘接剂渗入酸蚀后牙釉质表面形成的树脂钉突长度。
Methods To test and compare the shear bond strength and the penetration depth of resin tags of fluoride-releasing orthodontic adhesives with those of the traditional orthodontic adhesive.
组传统预备方法的树脂-牙本质界面可见混合层，圆锥型树脂突和侧枝连接的形成；
In Group B, the dentin-resin interface of conventionally prepared cavity showed the formation of the hybrid layer, funnel shaped resin tags and adhesive lateral branches.
全酸蚀粘结系统与自酸蚀粘结系统作用同类型的牙本质上，自酸蚀比全酸蚀形成的混合层薄，树脂突短。
When bonding the same type dentin substrate, the resin rags were shorter and the hybrid layer thinner in used self-etching adhesive than total-etching adhesive.
