中文摘要
目的比较4种粘接剂对牙本质的粘接强度，并观察粘接界面，评估其抗力性能。方法采用Prime & BondNT（PBNT）、Tetric N-Bond（TNB）、Clearfil SE Bond（CSEB）、G Bond（GB）4种粘接剂粘接树脂于离体下颌第三磨牙的咬合面和近中面，近中面进行剪切力实验，记录断裂峰值；咬合面部分进行微拉伸粘接强度（TBS）测定，扫描电镜观察粘接界面形态。结果在剪切力实验中，PBNT与TNB的抗剪切粘接强度（SBS）最大，两者间差异无统计学意义（P>0.05）。PBNT的SBS高于CSEB与GB（P0.05）。与剪切力实验结果一致，PBNT和TNB的TBS高于CSEB和GB（P
英文摘要
Objective To compare the adhesive strength and observe the bonding interface. According to statistic analysis and scanning electron microscope（SEM） observation, the resistance capacity of four adhesive systems is evaluated. Methods Prime & Bond NT（PBNT）, Tetric N-Bond（TNB）, Clearfil SE Bond（CSEB）, G Bond（GB） were bonded to the occlusal surfaces and mesial surfaces of third molars respectively. The mesial resins received shear force experiment and the fracture load were recorded. The tensile bond strength（TBS） of the remaining parts were tested. The interfacial configuration were observed under SEM. Results In the shear bond strength（SBS） experiment, PBNT and TNB showed the best result, but there was no significant difference between them（P>0.05）. The SBS of PBNT was stronger than that of CSEB and GB（Psignificant difference between TNB and CSEB（P>0.05）. In accordance with the shear force result, the TBS of PBNT and TNB was larger than CSEB and GB（P
