This study examined the effect of different enamel and dentin conditioning times on the shear bond strength of a resin composite using etch-and-rinse and self-etch adhesive systems. Shear bond strengths were determined following treatment of flat ground human enamel and dentin surfaces (4000 grit) with 11 adhesive systems: 1) AdheSE One Viva Pen-(ASE), 2) Adper Prompt L-Pop-(PLP), 3) Adper Single Bond Plus-(SBP), 4) Clearfil SE Bond-(CSE), 5) Clearfil S3 Bond-(CS3), 6) OptiBond All-In-One-(OBA), 7) OptiBond Solo Plus-(OBS), 8) Peak SE-(PSE), 9) Xeno IV-(X4), 10) Xeno V-(X5) and 11) XP Bond-(XPB) using recommended treatment times and an extended treatment time of 60 seconds (n = 10/group). Composite (Z100) to enamel and dentin bond strengths (24 hours) were determined using Ultradent fixtures and debonded with a crosshead speed of 1 mm/minute. The data were analyzed with a three-way Analysis of Variance (ANOVA) and Fisher's LSD post hoc test. The highest shear bond strengths (MPa) to enamel were achieved by the three etch-and-rinse systems at both the recommended treatment time (SBP-40.5 +/- 6.1; XPB-38.7 +/- 3.7; OBS- 35.2 +/- 6.2) and the extended treatment time (SBP-44.5 +/- 8.1; XPB-40.9 +/- 5.7; OBS-35.0 +/- 4.5). Extending the enamel treatment time did not produce a significant change (p > 0.05) in bond strength for the 11 adhesive systems tested. OBS generated the highest (46.2 +/- 7.9) bond strengths to dentin at the recommended treatment time. At the extended treatment time X4 (42.2 +/- 11.7), PSE (42.1 +/- 9.7) and OBS (41.4 +/- 8.0) produced the highest bond strengths to dentin. The bond strength change between recommend and extended treatment times was significant (p < 0.05) for PSE, but the other 10 systems did not exhibit any significant change.
本研究旨在探讨不同牙釉质和牙本质处理时间对使用酸蚀-冲洗和自酸蚀黏结系统的树脂复合材料的剪切黏结强度的影响。处理后，对经过 4000 目砂纸打磨的平整人牙釉质和牙本质表面（4000 目砂纸）用 11 种黏结系统进行处理：1）AdheSE One Viva Pen（ASE），2）Adper Prompt L-Pop（PLP），3）Adper Single Bond Plus（SBP），4）Clearfil SE Bond（CSE），5）Clearfil S3 Bond（CS3），6）OptiBond All-In-One（OBA），7）OptiBond Solo Plus（OBS），8）Peak SE（PSE），9）Xeno IV（X4），10）Xeno V（X5）和 11）XP Bond（XPB），使用推荐的处理时间和 60 秒的延长处理时间（n = 10/组）。使用 Ultradent 夹具测定 24 小时后复合树脂（Z100）与牙釉质和牙本质的黏结强度，并以 1mm/min 的十字头速度进行分离。采用三因素方差分析（ANOVA）和 Fisher LSD 事后检验对数据进行分析。在推荐的处理时间下，三种酸蚀-冲洗系统的牙釉质剪切黏结强度最高（MPa）：SBP-40.5 ± 6.1；XPB-38.7 ± 3.7；OBS-35.2 ± 6.2）和延长的处理时间（SBP-44.5 ± 8.1；XPB-40.9 ± 5.7；OBS-35.0 ± 4.5）。对 11 种黏结系统进行测试，延长牙釉质处理时间不会对黏结强度产生显著变化（p＞0.05）。OBS 在推荐的处理时间下对牙本质的黏结强度最高（46.2 ± 7.9）。在延长的处理时间下，X4（42.2 ± 11.7）、PSE（42.1 ± 9.7）和 OBS（41.4 ± 8.0）对牙本质的黏结强度最高。PSE 的推荐和延长处理时间之间的黏结强度变化具有统计学意义（p＜0.05），但其他 10 个系统没有显示出任何显著变化。
