目的：本研究的目的是确定聚合收缩应力的影响可能对债券durability.Methods：粘接效果进行了评估，通过微拉伸粘接强度测试（muTBS）和电子显微镜。测定平坦牙本质表面和标准化腔中的muTBS（这在1天和1年水储存之后）。应用了代表所有当前类别的六种粘合剂：两种蚀刻和冲洗（OptiBond FL，Kerr; Scotchbond 1，3 M ESPE），两个自蚀刻（Clearfil SE Bond，Kuraray; Adper Prompt，3 M，ESPE）和两种玻璃离聚物（Fuji Bond LC，GC; Reactmer，Shofu）粘合剂。传统的3步蚀刻和冲洗粘合剂OptiBond FL最有效地粘合到牙本质，并且似乎对聚合收缩应力和水降解不敏感。两步自蚀刻粘合剂Clearfit SE Bond最接近这种上级粘合效果，并且在1年的水暴露后仅略微损失粘合强度。两步蚀刻和冲洗粘合剂Scotchbond 1和“强”一步自蚀刻粘合剂Adper Prompt对腔体结构和水老化效应非常敏感。两步树脂改性的玻璃离子粘合剂富士债券LC只遭受收缩应力，而不是从1年的水暴露。值得注意的是，尽管1天的muTBS非常低，但当在水中储存1年时，“温和”1步玻璃离子粘合剂Reactmer的明显可修复性也是显著的：简化的粘合程序不一定意味着改善的粘合性能，特别是在长时间内。(C)2004年牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
Objectives: The purpose of this study was to determine the effect polymerization contraction stress may have on bond durability.Methods: Bonding effectiveness was assessed by micro-tensile bond strength testing (muTBS) and electron microscopy. The muTBS to flat dentin surfaces and in standardized cavities was determined (this after 1 day as well as 1 year water storage). Six adhesives representing all current classes were applied: two etch-and-rinse (OptiBond FL, Kerr; Scotchbond 1, 3M ESPE), two self-etch (Clearfil SE Bond, Kuraray; Adper Prompt, 3M, ESPE) and two glass-ionomer (Fuji Bond LC, GC; Reactmer, Shofu) adhesives.Results: The conventional 3-step etch-and-rinse adhesive OptiBond FL bonded most effectively to dentin, and appeared insensitive to polymerization shrinkage stress and water degradation. The 2-step self-etch adhesive Clearfit SE Bond most closely approached this superior bonding effectiveness and only slightly lost bond strength after 1-year water exposure. The 2-step etch-and-rinse adhesive Scotchbond 1 and the 'strong' 1-step self-etch adhesive Adper Prompt appeared very sensitive to cavity configuration and water-aging effects. The 2-step resin-modified glass-ionomer adhesive Fuji Bond LC only suffered from shrinkage stress, but not from 1-year water-exposure. Remarkable also is the apparent repairability of the 'mild' 1-step glass-ionomer adhesive Reactmer when stored for 1 year in water, in spite of the very tow 1-day muTBS.Significance: Simplified bonding procedures do not necessarily imply improved bonding performance, especially in the tong term.
