The efficacy of dentin bonding systems composed of a commercial or an experimental dentin cleanser, a dentin primer, and an intermediate resin was examined by measurement of the wall-to-wall polymerization contraction gap. Light-activated composites in a cylindrical dentin cavity were prepared in exposed dentin of the proximal surface of the extracted human premolar. The combination of a dentin cleanser of neutralized 0.5 mol/L EDTA, a dentin primer of 35% hydroxyethyl methacrylate (HEMA) or 35% HEMA containing 5% glutaraldehyde and a commercial intermediate resin (Clearfil New Bond, Kuraray Co., Osaka, Japan; Pyrofil Light Bond, Sankin Co., Osaka, Japan) was effective in compensating for the contraction stress of a light-activated composite and for obtaining marginal integrity between the composite and the dentin cavity wall.
通过测量壁间聚合收缩间隙，研究了由市售或实验性牙本质清洁剂、牙本质底漆和中间树脂组成的牙本质粘结系统的功效。在拔除的人类前磨牙近中面暴露的牙本质中制备圆柱形牙本质腔中的光固化复合材料。中和的0.5mol/L乙二胺四乙酸（EDTA）牙本质清洁剂、35%甲基丙烯酸羟乙酯（HEMA）或含5%戊二醛的35%HEMA牙本质底漆与市售中间树脂（Clearfil New Bond，日本大阪可乐丽公司；Pyrofil Light Bond，日本大阪三金公司）的组合可有效补偿光固化复合材料的收缩应力，并在复合材料与牙本质腔壁之间获得边缘完整性。
