摘要
目的评价各种牙体缺损桩核修复方法失败率,为临床应用提供指导。方法通过计算机及手工检索有关根管治疗后桩核修复的临床随机对照和半随机对照试验,评价纳入文献的质量并进行系统评价。结果共检索出2 100篇文献,有6篇符合纳入标准,其中3篇为比较纤维桩和金属桩修复效果的试验,Meta分析结果显示,使用纤维桩和金属桩修复短期疗效差异无统计学意义;3篇为比较使用纤维桩和不使用桩修复效果的试验,Meta分析结果显示4个侧壁缺失有箍效应并已行根管治疗的患牙,使用纤维桩修复较不使用桩修复失败率低。结论 4个侧壁缺失的患牙应使用纤维桩修复;现有的研究结果尚不能判断纤维桩与金属桩修复根管治疗后牙体缺损的临床效果何者更为优越,仍需更多临床随机对照试验的结果进行验证。
Objective The aim of this systematic review was to assess the effectiveness of different post and core techniques on restoration of endodontically treated teeth. Methods The literature search was complemented by manual searching. Randomized or quasi-randomized controlled clinical trails about the failure of different post and core restorations in treatment of endodontically treated teeth were collected. The quality of the included stud- ies was assessed. Results From 2 100 titles after the literature search, six articles met the inclusion criteria. Three were comparative evaluations of fiber post and metal post, the short term result indicated that there, were no significant differences in failure rate of fiber post and metal post; and the others were the clinical evaluations of fiber post and restoration without post, the conclusion of superiority of metal post or fiber post could not the made in such a middle term result, but the results indicated that when no coronal wall was retained but ferrule effect obtained, fiber post restoration had favorable clinical outcome than no post restoration. Conclusion The use of fiber post can increase the survival rate of endodontically treated teeth when teeth missing all the coronal Walls regardless of the presence or absence of a ferrule effect. The clinical outcomes have no differences no matter the post and core system is fiber post or metal post. But more randomized controlled trials are needed to confirm this conclusion.
