预留桩道对纤维桩固位影响的临床研究(1)
[摘要] 目的 通过临床观察探讨根充时预留桩道，两周后桩道预备的可行性。 方法 整群选择2012年8—10月在北京市顺义区医院口腔科就诊的前牙缺损患者96颗前牙，将其随机平均分成2 组，每组48颗：Ⅰ组： 根充时预留桩道，两周后桩道预备纤维桩修复； Ⅱ组： 根管常规热牙胶垂直加压充填，两周后桩道预备，纤维桩修复。随访两年，观察 固位情况。结果Ⅰ组 2颗患牙纤维桩脱落，成功率为96%； Ⅱ组3颗患牙纤维桩脱落，成功率为94%。两组治疗成功率比较差异无统计学意义(P>0.05)。结论 预留桩道两周后桩道预备具有良好的临床应用价值。

[Abstract] Objective To study the clinical effects of reserved post space during the root canal filling？and post space preparation was performed two weeks later. Methods Group selection a total of 96 anterior tooth in the hospital of Shunyi District Beijing from August to October in 2012 were collected. They were randomly divided into two groups equally. Ⅰgroup ： Reserve the post space during root canal filling and two weeks later post space preparation was performed. Ⅱgroup：Post space preparation were performed 2 weeks later after normal root canal filling. Follow -up for 2 years to observe the fiber post retention. Results Two teeth failed in Group Ⅰ ......
