The aim of this study was to determine the bonding effectiveness of four self-etching primer adhesives after various tooth preparation protocols. Enamel/dentin specimens were prepared from 84 permanent molars, divided into three enamel preparation groups (silicon carbide paper [SiC1; erbium, chromium:yttri-um, scandium, gallium, garnet [Er,Cr:YSGG] laser [EL] and diamond bur [DB]) and five dentin preparation groups (SiC, EL, DB, steel[SB], and ceramic burs [CBs]). In each group,specimens were equally divided into four sub-groups and were bonded using Clearfil SEBond (CSE, Kuraray), Xeno IV (XE, Dentsply),Tokuyama Bond Force (TK, Tokuyama) and Filtek Silorane System Adhesive (FS, 3MESPE), as well as a hybrid resin composite(Clearfil Majesty Esthetic, Kuraray) for CSE,XE, and TK, and Filtek Posterior Restorative(3M ESPE) for FS). After 24 hours of water storage at 370C, microshear bond strength(iSBS) testing was carried out. Data were analyzed using analysis of variance (ANOVA)-Tukey test at a=0.05 and bond failure modes assessed. Representative debonded specimens were prepared and examined under the scanning electron microscope (SEM). All adhesives exhibited no significant differences in 1SBS on enamel and dentin under the clinical cavity preparation protocols, except for TK on den-tin. SEM revealed areas of altered subsurface enamel/dentin following EL ablation.
本研究旨在确定四种自酸蚀底漆黏结剂在不同牙体预备方案后的黏结效果。从 84 颗恒磨牙制备牙釉质/牙本质标本，分为三组牙釉质预备组（碳化硅砂纸 [SiC1]；铒铬：钇钪镓石榴石 [Er,Cr:YSGG]激光 [EL]和钻石车针 [DB]）和五组牙本质预备组（SiC、EL、DB、钢[SB]和陶瓷车针 [CBs]）。每组标本再分为四等份，分别使用 Clearfil SEBond（CSE，可乐丽）、Xeno IV（XE，登士柏）、Tokuyama Bond Force（TK，可乐丽）和 Filtek Silorane System 黏结剂（FS，3M ESPE），以及 Clearfil Majesty Esthetic（CSE、XE 和 TK）和 Filtek Posterior Restorative（3M ESPE）黏结 FS 进行黏结。在 37°C 下储存 24 小时后，进行微剪切黏结强度（iSBS）测试。采用方差分析（ANOVA）-Tukey 检验（α=0.05）对数据进行分析，并评估黏结失败模式。制备代表性的离断标本，在扫描电子显微镜（SEM）下观察。除 TK 处理牙本质外，所有黏结剂在临床窝洞预备方案中对牙釉质和牙本质的 1SBS 均无显著差异。SEM 显示 EL 消融后牙本质的亚表面发生了改变。
