(1)Short-term bonding effectiveness1)Effect of surface difference to be bondedIt is important to select a bur for preparation of the tooth surface in order to achieve a better tooth/adhesive bond, when using self-etching or one-step type adhesives2)Classification of resin/dentin interface produced by simplified-step adhesivesOne-step self-etching adhesives could be classified into three categories, etch-and-rinse type, mild self-etching type, and nano-interaction zone type, by their morphological appearance of the interface. It was proposed that "Nano-interaction zone" is a new complementary classification for partially demineralized resin-dentin inter-diffusion zones.(2)Long-term bonding effectiveness1)Two-step mild self-etching adhesiveThe results of this research supported the concept that long-term durability of adhesive-dentin bonds depended on the chemical bonding potential of the functional monomer.2)One-step adhesiveThe results of a 100,000-cycle thermo-stress experiment suggested that a certain degree of degradation in the resin-dentin interface occurred and it depended on the adhesives used.(3)Comparative study on adhesive performance of functional monomersBesides self-etching dentin, specific functional monomers had additional chemical bonding efficacy that was expected to contribute to their adhesive potential to tooth tissue.Further research should be performed on the smear layer that might affect the bonding effectiveness of the simplified-step adhesive systems.

（1)短期粘接效果(1)待粘接表面差异的影响当使用自蚀刻或一步式黏合剂时，为了达到更好的牙/粘接剂粘接效果，选择一种材料来制备牙表面是很重要的。2）简化步式黏合剂产生的树脂/牙本质界面分类一步式自蚀刻黏合剂可分为蚀刻-冲洗型、轻度自蚀刻型和纳米相互作用带型三种类型。通过它们的界面形态呈现。提出“纳米相互作用区”是对部分脱矿树脂-牙本质互扩散区的一种新的补充分类。(2)长期粘接效果本研究的结果支持了粘接剂-牙本质键的长期耐久性取决于功能单体的化学键电位的概念。10万次热应力实验结果表明，树脂-牙本质界面发生了一定程度的降解，这取决于所使用的胶粘剂。(3)功能单体与牙本质黏附性能的比较研究除了自噬牙本质外，特定功能单体还具有额外的化学黏附效能，这将有助于其对牙组织的黏附潜力。对可能影响简化步接体系粘接效果的涂抹层进行进一步的研究。
