摘　　要：背景:目前大多数对纤维桩表面处理的研究都是模拟口腔状况的体外实验,不能模拟真正的口腔环境条件,因此临床研究评估纤维桩的各种表面处理对黏结效果的影响非常重要。目的:研究玻璃纤维桩经4种不同方法表面处理后修复牙体缺损的临床疗效。方法:选择完善根管治疗后需行桩核冠修复的牙体缺损患者178例,共201颗患牙,按照纤维桩表面处理方式随机分为4组:A组(51牙)纤维桩粘接前表面不作处理,B组(51牙)粘接前表面进行喷砂处理,C组(53牙)粘接前表面进行过氧化氢溶液处理,D组(46牙)粘接前表面进行硅烷偶联剂涂布。4组患者经纤维桩及全瓷单冠修复后行3个月至2年的临床随访,观察修复效果。结果与结论:B组、C组修复成功率高于A组、D组(P<0.05),B组与C组、A组与D组修复成功率比较无差异;分析4组患牙修复失败的原因,牙根折断、桩核松脱、桩核折断等是主要原因,但4组间牙根折断、桩核松脱、桩核折断的失败发生率无差异(P>0.05);B组、C组修复效果生存率好于A组(P<0.05),A组与D组、B组与C组修复效果生存率无差异(P>0.05)。结果表明,对纤维桩表面进行喷砂和过氧化氢溶液处理均能改善纤维桩修复牙体缺损的临床效果,减少修复失败率。BACKGROUND： Most current studies on the surface treatment of fiber posts are in vitro experiments aiming to simulate oral conditions, but it is impossible to simulate the actual conditions of oral environment. Therefore, clinical studies on the adhesion effects of fiber posts with various surface treatments are of great importance.OBJECTIVE： To evaluate the clinical effect of four different surface treatments of glass-fiber posts on the restoration of tooth defects.METHODS： A total of 178 patients（201 teeth） with dental defect who were treated by root canal treatment and scheduled for crown repair were randomly divided into four groups according to the surface treatment of fiber posts： no surface treatment in group A（n=51） was performed before bonding; group B（n=51） was restored with glass-fiber posts sandblasted before bonding; group C（n=53） was treated with hydrogen peroxide solution on the surface of the fiber post before bonding; and group D（n=46） was treated with silane coupling agent on the surfaceof the fiber post before bonding. Clinical follow-up to observe the restorative effect was done for 3 months to 2 years after restoration. RESULTS AND CONCLUSION： The success rate of dental restoration in groups B and C was significantly higher than that in groups A and D（P〈0.05）, but there was no significant difference between groups B and C as well as between groups A and D（P〉0.05）. The failure in dental restoration mainly resulted from root fracture, loosening and fracture of the post core. The incidence of root fracture, post core loosening and fracture, however, showed no difference among the four groups（P〉0.05）. The survival rate of the patient＇s restorative effect in groups B and C was better than that in group A（P〈0.05）, and there was no significant difference in the survival rate of the patient＇s restorative effect between groups A and D as well as between groups B and C（P〉0.05）. Overall findings indicate that the surface treatment of fiber p
