摘要：

背景：粘接界面尤其是根管壁-粘接剂间是纤维桩修复后接构的薄弱环节，加强粘接剂与根管壁间粘接对提高纤维桩的修复成功率，有重要临床指导意义。
目的：比较自酸蚀粘接系统和全酸蚀粘接系统对纤维桩粘接强度的影响。
方法：选用30颗单根管前牙用于纤维桩粘接实验，每颗牙选用逐步后退法进行预备并进行根管充填。样本分为3组，自酸蚀粘接组、全酸蚀粘接组和空白对照组分别应用自酸蚀粘接系统、全酸蚀粘接系统、传统磷酸酸蚀法处理根管内壁。
结果与结论：自酸蚀粘接组、全酸蚀粘接组和空白对照组的粘接强度分别为(3.24±0.76)，(4.09±0.54)，(2.85±0.89) MPa。两两相比，不同粘接方法对纤维桩的粘接强度差异均有显著性意义(P < 0.05)；扫描电镜观察发现全酸蚀粘接组混合层与牙本质和纤维桩粘接紧密，自酸蚀粘接组混合层只与纤维桩粘接紧密，与牙本质未形成有效连接。提示全酸蚀粘接系统的粘接强度优于自酸蚀粘接系统，具有良好的纤维桩固位性能。

Abstract:

BACKGROUND: The interface between resin and dentin bonded is a weak structure. So it is significant to develop a better bonding system.
OBJECTIVE: To investigate the effect of self-etching system and general etching system on bond strength of fiber posts.
METHODS: Thirty human intact signal-rooted canals were prepared using step-back technique and obturated with gutta-percha using lateral condensation. The roots were divided into three groups and received different bond systems. Group A used self-etching system, group B used general etching system, and group C was blank control group.
RESULTS AND CONCLUSION: The bond strength of groups A, B, C was (3.24±0.76), (4.09±0.54), (2.85±0.89) MPa. Significant difference was found among different etching systems (P < 0.05). Scanning electron microscope observation found that in group B, fiber post and dentin were connected better than group A. Good marginal seal was observed in group B. General etching system is the best way to cement fiber posts, and the bond strength with general etching system is higher than that with self-etching system.
