目的：本研究的目的是确定双层应用的通用粘合剂对粘结质量的影响，并与其他粘合剂system.Methods比较：本研究中使用的两种通用粘合剂：Scotchbond Universal（SU），[3 M ESPE]和Prime & Bond elect（PE），[Dentsply Caulk]。常规的单步自蚀刻粘合剂G-aenial Bond（GB），[GC Corporation.]和BeatitiBond（BB），[Shofu Inc.]，和两步自蚀刻粘合剂Optibond XTR（OX），[Kerr Corporation]用作对比粘合剂。在单次和双次应用模式下测量了牙釉质和牙本质的剪切粘结强度（SBS）和剪切疲劳强度（SFS）。结果：两种粘接剂的牙釉质和牙本质的SBS均显著高于单种粘接剂的SBS。此外，双涂模式中的通用粘合剂具有显著高于单涂模式的牙本质SFS值。两步自酸蚀粘合剂OX往往有较低的粘结强度在双应用模式，无论测试方法或粘附substrate.Conclusion：双应用模式是有效的，在增强SBS和SFS的通用胶粘剂，但不是传统的两步自酸蚀粘合剂。重要性：这些结果表明，虽然双重应用模式可以提高通用粘合剂的粘合质量，但在临床使用中，它可能会对两步自蚀刻粘合剂产生反作用。
Objectives: The aim of this study was to determine the effect of double-layer application of universal adhesives on the bond quality and compare to other adhesive systems.Methods: Two universal adhesives used were in this study: Scotchbond Universal (SU), [3M ESPE] and Prime & Bond elect (PE), [Dentsply Caulk]. The conventional single-step self-etch adhesives G-aenial Bond (GB), [GC Corporation.] and BeatitiBond (BB), [Shofu Inc.], and a two-step self-etch adhesive, Optibond XTR (OX), [Kerr Corporation], were used as comparison adhesives. Shear bond strengths (SBS) and shear fatigue strengths (SFS) to human enamel and dentin were measured in single application mode and double application mode. For each test condition, 15 specimens were prepared for SBS testing and 30 specimens for SFS testing.Results: Enamel and dentin SBS of the universal adhesives in the double application mode were significantly higher than those of the single application mode. In addition, the universal adhesives in the double application mode had significantly higher dentin SFS values than those of the single application mode. The two-step self-etch adhesive OX tended to have lower bond strengths in the double application mode, regardless of the test method or adherent substrate.Conclusion: The double application mode is effective in enhancing SBS and SFS of universal adhesives, but not conventional two-step self-etch adhesives. Significance: These results suggest that, although the double application mode may enhance the bonding quality of a universal adhesive, it may be counter-productive for two-step self-etch adhesives in clinical use.
