摘　　要：目的比较在水浴24 h及冷热循环5000次条件下,氧化锆表面不同处理方式对自粘接双固化树脂水门汀剪切粘接强度(SBS)的影响。方法切割烧结6个边长为2 cm的正方体氧化锆试件。采用3种自粘接双固化树脂水门汀(Clearfil SAC、RelyX U200、Multilink Speed)进行粘接,根据粘接方式分为直接粘接组(直接涂布树脂水门汀)、粘接剂组(应用与树脂水门汀搭配的通用型粘接剂后涂布树脂水门汀)、底涂剂组(应用底涂剂Z-Prime Plus后涂布树脂水门汀),每组又根据处理方式分为37℃恒温水浴24 h和冷热循环5000次2个亚组。对各组试件进行SBS测试,采用SPSS 19.0软件进行单因素方差分析。利用体视显微镜观察氧化锆断裂模式。结果水浴24 h后,3种树脂水门汀的粘接剂组和底涂剂组SBS均高于直接粘接组(P<0.05),而粘接剂组和底涂剂组间SBS无统计学差异(P>0.05)。冷热循环处理后,3种树脂水门汀各组SBS均降低(P<0.05),粘结剂组SBS高于直接粘接组和底涂剂组(P<0.05)。断裂模式分析表明,与水浴处理相比,冷热循环处理后Ⅲ类断裂模式明显增多。结论通用型粘接剂与底涂剂均能改善自粘接双固化树脂水门汀37℃水浴24 h的粘接强度。通用型粘接剂作为氧化锆表面处理剂的粘接耐久性优于底涂剂。Objective This study aimed to compare the effects of water storage treatment and thermal cycling on the shear bond strength(SBS)of three self-adhesive dual-cure resin cements.Methods Six cubic zirconia specimens with side length of 2 cm were obtained by cutting and sintering.Three self-adhering dual-cure resin cements(i.e.,Clearfil SAC,RelyX U200,and Multilink Speed)were selected.According to their bonding modes,they were divided into three groups:direct bonding group(direct coating with resin cement),adhesive group(applying universal adhesives and then coating with resin cement),and primer group(applying Z-Prime Plus and then coating with resin cement).According to experimental conditions,each group was divided into two subgroups:subgroup a(water storage at 37℃for 24 h)and subgroup b(thermalcycling for 5000 times).SBS data were analyzed by one-way ANOVA by using SPSS 19.0 software(P<0.05).The fractured zirconia surface was observed under a stereomicroscope.Results After water storage for 24 h,the SBS of the adhesive group and the primer group of the three resin cements was higher than that of the direct adhesive group(P<0.05),but the difference in SBS between the adhesive group and the primer group was not significant(P>0.05).After thermalcycling,the SBS of the three types of resin cements decreased(P<0.05);the SBS of the adhesive group was higher than that of the direct adhesive group and the primer group(P<0.05).Fracture mode analysis revealed that the typeⅢfracture mode evidently increased after the thermalcycling treatment compared with the water storage treatment.Conclusion The universal adhesives and the primer can improve the SBS of self-adhesive dual-cure resin cement in water storage at 37℃for 24 h.The universal adhesives had a better bonding durability than the zirconia primer.
