We have reported that Phosphoric Methacrylate adhesive resin (Panavia21, Kuraray, Japan) has strong adhesion and excellent adhesive durability to dentin pretreated with H_3PO_4 and NaClO.The purpose of this study was to clarify the adhesion mechanism between adhesive resin and dentin by TEM observations.The following results were obtained.1) Dentin treated with H_3PO_4 and NaOCl appeared to remain intact.2) Although it has been reported that a hybrid layr does not exist on dentin pretreated with H_3PO_4 and NaOCl, a very thin hybrid layr was observed in this study.3) When a self-etching primer was applied on dentin pretreated with H_3PO_4 and NaOCl, a hybrid layr containing resin-encapsulated hydroxylapatite was created in relatively intact dentin4) The reason for the excellent adhesive durability of the the hybrid layr on dentin pretreated with H_3PO_4 and NaOCl, in comparison with a hybrid layr formed in a denatured collagen layr, was thought to be due to the absence of smear and denatured collagen.

我们已经报道说，磷酸甲基丙烯酸酯粘附树脂（Panavia21，日本库拉雷）具有较强的粘附力和出色的粘合剂耐用性，可通过H_3PO_4和NACLO进行预处理的牙本质，本研究的目的是通过TEM进行粘合物和牙本质之间的粘附机制。 2）虽然据报道，在用H_3PO_4和NaOCL预处理的牙本质上不存在混合层，但在这项研究中观察到非常薄的杂化层。33）当在用H_3PO_4和naocl的hybrateyyl，hybrapeyyl，hybrap的hybrapeyyl上使用自我蚀刻底漆时是在相对完整的牙本质中创建的。与在变性胶原layr中形成的混合层相比，用H_3PO_4和NaOCl预处理牙本质上的混合层的粘合剂耐用性的原因是由于缺乏粘稠和变性的胶原蛋白。
