| 摘 要： | 目的研究纤维桩钉在不同粘结条件下的固位力,为临床选择合适的操作方法提供依据。方法根管壁牙本质和纤维桩表面分别经酸蚀、硅烷化处理后使用4种粘固材料(PermaCem双固化树脂水门汀;LuxaCore双固化树脂;Dulink双固化树脂水门汀;Rely-X Unicem双固化树脂水门汀)将桩钉粘固于离体人牙根管内,万能电子力学试验机测试其固位力,电子探针分析界面情况。结果根管壁牙本质经酸蚀后桩钉固位力平均值均大于未酸蚀组,处理前后数值有显著性差异(P<0.05);纤维桩表面硅烷化处理后固位力平均值均大于未硅烷化组,PermaCem组和LuxaCore组处理前后数值有显著性差异(P<0.05),但Dulink组和Rely-X Unicem组处理前后数值无统计学差异(P>0.05);两种表面处理方法粘结界面均显示了良好的粘结完整性。结论根管壁牙本质和纤维桩表面分别经酸蚀、硅烷化处理后,纤维桩固位力增大。
