The water-associated attributes of resin-dentin interfaces created by contemporary adhesives are important determinants of bond integrity and stability. In the present work, these attributes were estimated from the perspectives of causality, to examine the behavior of the first and most-recently launched versions of universal adhesives when applied in either the etch-and-rinse mode or the self-etch mode.
The immediate cause of interfacial permeability and the time-dependent cause of water sorption were investigated in conjunction with the intermediate effect of interface degradation and the more long-term effect of loss of mechanical strength, before and after thermomechanical cycling. The results were compared with control etch-and-rinse and self-etch adhesives.
Although the introduction of this new class of universal adhesives has brought forth significant changes to the dental adhesion arena, including more application options, reduced bonding armamentarium and increased user friendliness, the water-associated attributes that are critical for making resin-dentin bonds more durable to environmental challenges and less susceptible to degradation have remained unchanged at large, when compared with benchmarks established by former classes of adhesives.
It appears that the current trend of adhesive development has brought forth significant changes but lacks the vigor that demarcates progress and technological sublimity.
The advent of the user friendly universal adhesives has brought forth significant changes to the dental adhesion arena. However, the elements that are critical for making resin-dentin bonds more durable to environmental challenges and less susceptible to degradation have remained unchanged at large.
当代黏结剂所形成的树脂-牙本质界面的水相关特性是黏结完整性和稳定性的重要决定因素。本研究从因果关系的角度评估这些特性，以考察通用黏结剂的第一代和最新一代产品在酸蚀-冲洗模式或自酸蚀模式下的应用行为。
在热循环之前和之后，结合界面降解的中间效应和机械强度丧失的更长期效应，研究界面渗透性的即时原因和吸水性的时变原因，并与对照酸蚀-冲洗黏结剂和自酸蚀黏结剂进行比较。
尽管这类新型通用黏结剂的出现给牙科黏结领域带来了重大变化，包括更多的应用选择、更少的黏结器械和更高的用户友好性，但与前几代黏结剂建立的基准相比，对提高树脂-牙本质黏结耐久性以抵抗环境挑战和降低降解敏感性至关重要的水相关特性基本保持不变。
目前的黏结剂发展趋势带来了显著的变化，但缺乏界定进步和技术升华的活力。
用户友好型通用黏结剂的出现给牙科黏结领域带来了重大变化。然而，对于提高树脂-牙本质黏结耐久性以抵抗环境挑战和降低降解敏感性至关重要的因素基本保持不变。
