To compare the shear bond strength of the fractured anterior teeth reattached by two different adhesive materials.
Forty crown fractured anterior modes were divided into two groups randomly, with 20 in each group. Group A were reattached by Clearfil SE Bond and Clearfil AP-X, while group B were reattached by Clearfil S3 Bond and Clearfil AP-X. Then the specimens were submitted to an axial compression test in a universal testing machine until tooth fractured. The strength was recorded.
The mean shear bond strength of group A and group B was (324.32 +/- 65.91) N and (263.08 +/- 55.88) N, separately. The mean shear bond strength of group A was statistically higher than group B(t = 3.17, P = 0.000).
The shear bond strength of two-step adhesive Clearfil SE Bond is higher than one-step adhesive Clearfil S3 Bond for the reattachment of fractured anterior teeth.
比较两种不同粘结材料重新粘结折断前牙的抗剪切粘结强度。
将40颗冠折前牙模型随机分为两组，每组20颗。A组用Clearfil SE Bond和Clearfil AP-X重新粘结，而B组用Clearfil S3 Bond和Clearfil AP-X重新粘结。然后将标本在万能试验机上进行轴向压缩试验，直至牙齿折断。记录强度。
A组和B组的平均抗剪切粘结强度分别为（324.32±65.91）N和（263.08±55.88）N。A组的平均抗剪切粘结强度在统计学上高于B组（t = 3.17，P = 0.000）。
对于折断前牙的重新粘结，两步法粘结剂Clearfil SE Bond的抗剪切粘结强度高于一步法粘结剂Clearfil S3 Bond。
