目的：评价1种新型单瓶型多模式粘接剂在不同粘接模式下与牙本质的粘接强度和粘接耐久性。方法制作3组牙本质／复合树脂粘接试件，其中每组牙本质在粘接前接受不同的表面调节。包括不处理（空白对照），Singlebond Universal粘接剂自酸蚀模式下调节牙本质，Singlebond Universal粘接剂在酸蚀冲洗模式下调节牙本质。测量各组粘接试件水储24 h和180 d的微拉伸粘接强度值并进行统计分析。以扫描电子显微镜观察各组试件的粘接界面。结果不论老化前还是老化后，3组间的粘接强度均存在显著性差异，其中空白组的粘接强度值最低，另两组间则无显著性差异。人工老化使空白组的粘接强度值显著下降，而对另两组则并无显著影响。结论 Singlebond Universal粘接剂在自酸蚀粘接模式和酸蚀冲洗粘接模式下均能够形成与牙本质良好的粘接。%s: Objective To evaluate the dentin bonding strength and durability of a novel universal adhesive used in self⁃etch mode and etching⁃rinsing mode. Methods Three groups of dentin/composite resin bonding specimens were prepared, which received three kinds of dentin conditioning, including no treatment (control), Singlebond Universal in self⁃etch mode and in etching⁃rinsing mode. Micro tensile bond strength ( MTBS) after 24 hours’ and 180 days’ water storage was tested. The three different dentin/composite resin bonding interfaces were observed by a scanning electron microscope. Results Statistical differences existed in the bonding strength a⁃mong three groups both before and after aging, and the control group demonstrated the lowest bonding strength, while the other groups showed no significant differences. Artificial aging significantly decreased the bonding strength of the control group, while it exerted no effect on the other two groups. Conclusion Application of Singlebond Universal can demonstrate better dentin bond performance to composite resin in both self⁃etch mode and etching⁃rinsing mode.
