摘　　要：目的:评价根管治疗后患牙放置玻璃纤维桩与否对修复后长期成功率的影响。方法:临床上选择87例患者共119颗患牙,经完善的根管治疗后,根据剩余牙冠组织多少将患牙分成3组:两壁组,单壁组和无壁组,每组再按是否使用玻璃纤维桩随机分为两个亚组,之后患牙行金属烤瓷冠修复,并经过3年的临床疗效的追踪观察。结果:3年后总的总的成功率为86%(95/111),在两壁组中,有桩的修复成功率为100%,无桩的为95%(P=0.3173时序检验);在单壁组中,有桩的修复成功率为95%,无桩的为80%,(P=0.1556);在无壁组中,有桩的修复成功率为90%,无桩的为53%,(P=0.0220)。结论:对于根管治疗后的患牙,当剩余牙体组织少于两个壁存在时,建议使用玻璃纤维桩树脂核修复。但是,临床上也应该避免玻璃纤维桩的过度使用。Objective： The aim of this clinical trial was to assess whether the placement of a fiber post would affect the rate of success of single-unit postendodontic restorations.Methods： 87 patients providing 119 teeth were selected.Three groups were defined on the basis of the amount of residual coronal dentin： 2-walls group,1-wall group and no-wall group.Within each group teeth were randomized and allocated to 2 intervention groups,including subgroups no post and subgroups post.All teeth were treated with porcelain fused metal crown and followed up for 3 years.Results： In subgroups post of two-wall group,the success rates were 100%,and in subgroups no post,success rates of 95% were observed（P =0.3173 log-rank test）;In subgroups post of one-wall group,the success rates were 95%,and in subgroups no post,success rates of 80% were observed（P =0.1556）;In subgroups post of no-wall group,the success rates were 90%,whereas in subgroups no post,success rates of 53% were observed（P = 0.0220）.Conclusions： Within the observation time of the present study,fiber post placement is recommended to when the amount of residual coronal dentin is less than 2 walls.However,the overuse of fiber post should be avoided in clinic.
