Studies on improving the bond of composite regrative materials to the dentin surface.For improving the bond of composite regrative materials to the dentin cavity wall, some researchers reported the use of newly developed dentin treatment agents (dentin cleanser and/or dentin primer) and complicated manipulating methods. It seems to be difficult precisely to distinguish dentin and enamel in a small cavity and also to apply accurately enamel etching agents and dentin treatment agents to each respective region. An easier method of manipulation for tooth treatment is desirable for clinical use of composite materials.The purpose of this report is to determine the bond of experimental composite restrative materials containing 4 or 6 functional monomers conjunction with experimental bonding agents containing above noted polifunctional monomers.Four experimental bonding agents containing 4 or 6 functional monomersand six experimental restorative materials containing polifunctional monomers were prepared. Two commercially available dentin bonding agents, Clearfil New Bond (chemical cure type) and Clearfil Photo Bond (Light cure type) and light cure composite materials, Silux were used as controls.Results were as follows;1)Better marginal adaptation was obtained by use of experimental bonding agent containing 4 functional monomer than those by commercially available ones in measuring Wall-to-wall contraction gap in a dentin cavity.2)Experimental restrative materials containing 4 functional monomer in combination with the experimental bonding agent showed better marginal adaptation to dentin cavity than commercially available composite,in measuring contraction gap.

关于改善复合材料对牙本质表面的键的研究。对于改善复合材料与牙本质腔壁的键，一些研究人员报告说，使用新开发的牙本质治疗剂（牙本质清洁剂和/或牙本质引物）和复杂的操纵方法。在小腔中区分牙本质和搪瓷似乎很困难，并且也将准确的牙釉质蚀刻剂和牙本质处理剂应用于每个区域。可以临床使用复合材料的一种更简单的操纵方法。本报告的目的是确定含有4或6个功能单体共同结合的实验复合限制性材料的键，其中包含上述POLICSSTIOUNT POLICANTIONPANTIAM中的实验键合剂。四个或6个功能性的实验材料含有4或6个功能性的材料。两种商业上可用的牙本质键合剂，新的键（化学固化型）和透明胶片键（轻质固化型）和光治疗复合材料，将硅用作对照。换句话如下； 1）通过使用4个功能单体中的实验性孔盖（通过均可用孔盖上的实验量）来获得更好的边际适应性。在测量收缩缝隙中，含有4种功能单体的限制性材料与实验键合剂结合使用比市售复合材料表现出更好的边际适应性。
