To evaluate the effect of different saliva decontamination procedures on the shear bond strength of a one-step universal adhesive system (Single Bond™ Universal Adhesive, 3M ESPE, St. Paul, MN, USA).
The occlusal surfaces of 75 human third molars were ground to expose dentin. The teeth were divided into the following groups: Group 1 (control group): Single Bond™ Universal Adhesive was applied to the prepared tooth according to the manufacturer's recommendations and light cured; no contamination procedure was performed. Group 2: Bonding, light curing, saliva contamination, and dry. Group 3: Bonding, light curing, saliva contamination, rinse, and dry. Group 4: After the procedure performed in Group 2, reapplication of bonding. Group 5: After the procedure performed in Group 3, reapplication of bonding. Then, composite resins were applied with cylindrical-shaped plastic matrixes and light cured. For shear bond testing, a notch-shaped force transducer apparatus was applied to each specimen at the interface between the tooth and composite until failure occurred. The data were statistically analyzed using one-way ANOVA.
One-way ANOVA revealed significant differences in shear bond strength between the control group and experimental Groups 2 and 4 (P < 0.05). No significant difference was found for experimental Groups 3 and 5 when compared to the control group (P > 0.05).
The present in vitro study showed that water rinsing is necessary if cured adhesive resin is contaminated with saliva to ensure adequate bond strength.
评估不同唾液去污程序对一步通用粘结系统（单键通用粘结剂，3M ESPE，美国明尼苏达州圣保罗）剪切粘结强度的影响。
将75颗人类第三磨牙的咬合面磨平以暴露牙本质。牙齿被分为以下几组：第1组（对照组）：按照制造商的建议将单键通用粘结剂应用于制备好的牙齿并光固化；未进行污染程序。第2组：粘结、光固化、唾液污染、干燥。第3组：粘结、光固化、唾液污染、冲洗、干燥。第4组：在第2组进行的程序之后，重新进行粘结。第5组：在第3组进行的程序之后，重新进行粘结。然后，使用圆柱形塑料基质施加复合树脂并光固化。对于剪切粘结测试，在牙齿与复合材料之间的界面处对每个标本应用缺口形力传感器装置，直至发生破坏。使用单向方差分析对数据进行统计分析。
单向方差分析显示对照组与实验组2和4之间的剪切粘结强度存在显著差异（P < 0.05）。与对照组相比，实验组3和5未发现显著差异（P > 0.05）。
目前的体外研究表明，如果固化的粘结树脂被唾液污染，水冲洗对于确保足够的粘结强度是必要的。
