本体外研究旨在比较当前自酸蚀粘合剂与牙本质的微拉伸粘结强度（MTBS），并评价人工老化[（热循环（TC）和/或机械负荷（ML）]对MTBS和自酸蚀粘合剂纳米渗漏的影响。测试了两步式（AdhesSE Bond、Clearfil Protect Bond、Clearfil SE Bond、Optibond Self-Etch）和一步式（Hybrid Bond、G-bond、Clearfil Tri-S Bond和Adper Prompt L-Pop）自蚀刻粘合剂。形成树脂复合材料堆积物，并对样本进行10（4）TC、10（5）ML和10（4）/10（5）TC/ML处理。未老化样本作为对照。在对照组中，一步自酸蚀粘合剂和三种两步自酸蚀粘合剂（AdhesSE Bond、Clearfil Protect Bond和Clearfil SE Bond）的MTBS之间无显著差异（p > 0.05）。AdhesSE Bond和Clearfil Protect Bond的MTBS高于所有一步自蚀刻粘合剂和Optibond Self-Etch。Clearfil SE Bond的MTBS高于两种一步自酸蚀粘合剂（Adper Prompt L-Pop，G-bond）（p < 0.05）。与未老化对照组相比，TC没有降低（p > 0.05），但ML和TC/ML显著降低了所测试粘合剂的MTBS（p < 0.05）。两步自酸蚀粘合剂倾向于在牙本质中更容易发生内聚性失效。透射电子显微镜显示不同的纳米泄漏模式的粘合剂和混合层的所有粘合剂检查，和额外的银填充水通道的迹象后，TC/ML更容易检测。
This in vitro study was performed to compare the microtensile bond strengths (MTBS) of current self-etching adhesives to dentin and to evaluate the effects of artificial aging [(thermocycling (TC) and/or mechanic loading (ML)] on MTBS and on nanoleakage of self-etching adhesives. Two-step (AdheSE Bond, Clearfil Protect Bond, Clearfil SE Bond, Optibond Self-Etch) and one-step (Hybrid Bond, G-bond, Clearfil Tri-S Bond, and Adper Prompt L-Pop) self-etching adhesives were tested. Resin composite build-ups were created, and the specimens were subjected to 10(4) TC, 10(5) ML, and 10(4)/10(5) TC/ML. Non-aged specimens served as controls. In the control group, no significant differences were found among the MTBS of the one-step self-etching adhesives and among those of three two-step self-etching adhesives (AdheSE Bond, Clearfil Protect Bond, and Clearfil SE Bond) (p > 0.05). The MTBS of AdheSE Bond and Clearfil Protect Bond were higher than were those of all one-step self-etching adhesives and than those of Optibond Self-Etch. The MTBS of Clearfil SE Bond was higher than were those of two one-step self-etching adhesives (Adper Prompt L-Pop, G-bond) (p < 0.05). Compared with the non-aged controls, TC did not decrease (p > 0.05), but ML and TC/ML significantly decreased the MTBS of the adhesives tested (p < 0.05). Two-step self-etching adhesives tended to fail more cohesively in dentin. Transmission electron microscopy revealed different nanoleakage patterns in the adhesive and hybrid layers of all adhesives examined, and signs of additional silver-filled water channels were more readily detectable after TC/ML.
