本研究的目的是评价4-META/MMA-TBB树脂与人牙釉质的剪切结合强度和耐久性。采用含有4-META （Teeth primer， TP）和35-45%或60-65%浓度磷酸（K-Etchant Gel， KE和Super Bond C&B Red Activator， RA）的自蚀刻处理剂作为表面处理剂。采用甲基丙烯酸甲酯（MMA）基自聚合树脂（Super-Bond C&B）作为粘接剂。测定了热循环前后的剪切粘结强度。结果用非参数程序进行统计分析。TP组热循环后剪切键强度显著高于其他各组，KE组热循环后剪切键强度显著高于RA组。这些结果表明4-META是有效的。此外，当比较牙齿脱矿程度时，使用TP进行较少脱矿的表面处理是最有效的处理。
The purpose of this study was to evaluate the shear bond strength and durability of 4-META/MMA-TBB resin to human enamel. A self-etching primer that contained 4-META (Teeth Primer, TP) and 35-45% or 60-65% concentrations of phosphoric acid (K-Etchant Gel, KE, and Super Bond C&B Red Activator, RA) were used as the surface treatment agents. A methyl methacrylate (MMA)-based self-polymerizing resin (Super-Bond C&B) was used as a luting agent. The shear bond strength was determined both pre and post thermocycling. The results were statistically analyzed with a non-parametric procedure. The post-thermocycling shear bond strength of the TP group was significantly higher than that of other groups, and that of the KE group was significantly higher compared with the RA group. These results demonstrated that 4-META was effective. Furthermore, when the degree of tooth demineralization was compared, surface treatment with less demineralization using TP was the most effective treatment.
