关于新型一体式粘合剂粘接强度的数据仍然相对有限。这项研究比较了最近五种一体化自酸蚀预涂系统(G-Bond、One-Up Bond-F Plus、Clearfil S-3 Bond、Adper Prompt L-Pop and Go！)的微剪切粘结强度。使用广泛使用的两步自酸蚀预充系统(Clearfi SE Bond)，对人磨牙进行切片，并用600粒度的碳化硅纸完成。牙釉质和牙本质均用粘结剂粘结，粘接直径为0.7 mm。使用微剪切粘结测试方法，以1 mm/分钟的十字头速度测试粘结强度。用方差分析和Tukey‘s HSD检验计算平均粘结强度和标准差，结果表明两步自酸蚀系统对牙本质具有更高的粘结强度。然而，在牙釉质粘结强度方面，Clearfi SE Bond与G-Bond和Go！没有统计学差异；然而，所有其他材料的粘结强度在统计学上都较低。有必要对这些新材料进行临床检查，以确定其疗效。
Data on the adhesive strength of new all-in-one adhesives are still relatively limited. This study compared the microshear bond strengths of five recent all-in-one self-etching priming systems (G-Bond, One-Up Bond-F Plus, Clearfil S-3 Bond, Adper Prompt L-Pop and Go!) with a widely used two-step self-etching priming system (Clearfil SE Bond).Human molars were sectioned and finished with 600-grit SiC paper. Both enamel and dentin were bonded using adhesives with a 0.7 mm bonding diameter. Bond strengths were tested using a microshear bond test method at a crosshead speed of 1 mm/minute. The mean bond strengths and standard deviations were calculated and analyzed using ANOVA and the Tukey's HSD test.Results showed the two-step self-etching system had significantly higher bond strengths to dentin. However, for enamel bond strength, Clearfil SE Bond showed no statistical difference to G-Bond and Go!; however, all of the other materials were statistically lower. It is necessary to examine these new materials clinically to determine their efficacy.
