单合一粘合剂与水相关的问题有关，例如相分离、聚合抑制和保存期缩短。在这项研究中，我们调查了这些问题是否可以避免的无水自蚀刻粘合剂，需要一个“湿粘合”的应用程序。此外，这样一个系统的技术敏感性进行了evaluated. METHODS的微拉伸粘结强度（μTBS）的无水和含水的实验一步粘合剂（EXP）粘接到“空气干燥”，“斑点干燥”或“过湿”钻切牙釉质和牙本质进行了测定。同样地，测定了市售无水粘合剂Absolute 2（Denstell-Sankin）的μTBS。通过SEM和TEM评价了胶粘剂的界面相互作用。在吸干组中，两种无水胶粘剂都获得了最高的粘结强度，并且无水EXP的粘结强度与含水EXP粘结到风干表面的粘结强度相当。当它们被施加到过湿表面时，无水粘合剂倾向于较低的粘合强度。这部分归因于粘合剂层中存在相分离（或“过湿”）液滴。出乎意料的是，即使在风干的牙本质上，无水粘合剂也能够使牙本质脱矿，但是在有限的程度上，因此损害了粘结强度。然而，不排除这些粘合剂中与水有关的问题，因为它们最终在应用过程中也与水混合。因此，他们部分未能实现其目标。此外，它们的粘合过程涉及“湿粘合”，比干粘合对技术更敏感。
OBJECTIVESAll-in-one adhesives have been associated with water-related problems, such as phase-separation, polymerization-inhibition and reduced shelf life. In this study we investigated whether these problems could be avoided by a water-free self-etch adhesive that requires a ‘wet-bonding’ application procedure. Additionally, the technique-sensitivity of such a system was evaluated.METHODSThe micro-tensile bond strength (μTBS) of a water-free and a water-containing experimental one-step adhesive (EXP) bonded to either ‘air-dried’, ‘blot-dried’ or ‘overwet’ bur-cut enamel and dentin was determined. Likewise, the μTBS of a commercial water-free adhesive Absolute2 (Denstply-Sankin) was determined. The interfacial interaction of the adhesives was evaluated by SEM and TEM.RESULTSIn the blot-dried group, both water-free adhesives obtained the highest bond strength and the bond strength of the water-free EXP was comparable to that of the water-containing EXP bonded to an air-dried surface. When they were applied to overwet surfaces, the water-free adhesives tended towards a lower bond strength. This was partly attributed to the presence of phase-separation (or ‘overwet’) droplets in the adhesive layer. Unexpectedly, even on air-dried dentin, the water-free adhesives were able to demineralize dentin, however to a limited extent, hence impairing the bond strength.SIGNIFICANCEWater-free one-step adhesives are a valuable alternative for conventional water-containing one-step adhesives. However, water-related problems in these adhesives are not ruled out, as they are eventually also mixed with water during the application procedure. As such, they partially fail to meet their objective. In addition, their bonding procedure, which involves ‘wet bonding’, is more technique-sensitive than dry bonding.
