摘　　要：目的应用铸造金属桩核、纤维桩树脂核修复老年患者残冠、残根的临床效果及其影响临床成功率的因素。方法采用临床随机对照研究。66例需进行桩核修复的老年患者，平均年龄69．1岁，随机分为两组，每组33例：分别采用铸造金属桩核、石英纤维桩树脂核修复残根。于修复后1年、2年复查，观察临床疗效，失败者记录失败类型。采用Fisher确切概率法比较两组间的差异。结果两组病例牙龈指数和牙周指数实验牙与自身对照牙间分值差均为0。解剖形态、根管治疗失败、颜色匹配、边缘染色的复查失败病例比较差异均无统计学意义（均P〉0．05）。纤维桩树脂核修复组中，1例出现桩的脱落，1例出现纤维桩折断；铸造金属桩核修复组中，1例出现冠边缘染色，两组临床成功率间差异无统计学意义（93．9％比97．0％，P〉0．05）。结论老年患者采用纤维桩树脂核修复具有与铸造金属桩核相同的临床成功率。Objective To investigate the clinical performance of fiber post restorations in elderly patients with residual root and crown and to analyze the factors affecting the clinical success rate. Methods A total of 66 elderly patients requiring post restoration were selected. They were randomly divided into two groups： the observation group （n=33, restored with fiber post-resin cores） and the control group （n=33, restored with cast metal post-cores）. All patients were rechecked 1 year and 2 years after the restoration. The clinical efficacy and the failure types were recorded. The differences in clinical performance between the 2 groups were compared by using Fisher＇s exact test. Results The differences in the gingival index and periodontal index in the 2 groups between the experimental teeth and the control teeth were zero. There were no significant differences in dental morphology, root canal treatment failure, tooth color matching and marginal coloration between the 2 groups （all P〉0.05）. 1 case with post debonding and 1 case with fiber post fracture were found in the observation group and 1 case with marginal coloration was found in control group. There was no significant difference in clinical success rate between the 2 groups （93.94% vs. 96.97%, P〉0.05）. Conclusions The clinical success rate in fiber post-resin core restoration is the same as in cast metal post-cores restoration in elderly patients.
