The study was designed to evaluate the existing evidence on the failure rates of post-endodontic restorations retained with and without post in endodontically treated teeth (ETT).
Preferred Reporting Items for Systematic Reviews and Meta-Analyses- Protocol (PRISMA-P) guidelines were used to formulate the review.
Randomized controlled trials (RCT's) and prospective clinical studies comparing post endodontic restorations retained with and without post were included. PubMed/Medline, Embase, Cochrane Library and Scopus databases were searched to recognize relevant full-text articles in English language. The quality of the RCT's were evaluated using the Cochrane collaboration tool to assess the risk of bias and reported as having high, low or unclear risk. Random-effects model at a 95% confidence interval was used for the meta-analysis.
Meta-analyses was performed using the Mantel -Haenszel method31 and risk ratio, with a 95% confidence interval (CI), was estimated for dichotomous data. Random effects model32 was used as the pooling method and 95% confident interval (α = .05 for RR values) in Review Manager (RevMan) [Computer program]. Version 5.4. The Cochrane Collaboration, 2020).
Four studies comparing post retained and post free restorations in ETT with a total of 916 restorations were included in the analysis. The total risk ratio was 2.16, (95% CI:1.25 to 3.72).
ETT with post retained restorations exhibited significantly lower failure rates compared to restorations without post. Well-designed RCT's are warranted to develop a clinical protocol with respect to post-retained restorations.
本研究旨在评估根管治疗牙（ETT）中使用和不使用桩核保留后牙修复体的失败率的现有证据。
系统评价和荟萃分析首选报告项目（PRISMA-P）指南用于制定综述。
纳入了比较根管治疗后使用和不使用桩核保留后牙修复体的随机对照试验（RCT）和前瞻性临床研究。检索了 PubMed/Medline、Embase、Cochrane 图书馆和 Scopus 数据库，以识别英语全文文章。使用 Cochrane 协作工具评估 RCT 的质量，以评估偏倚风险，并报告为高、低或不确定风险。使用 95%置信区间的随机效应模型进行荟萃分析。
使用 Mantel-Haenszel 方法进行荟萃分析，31 使用风险比（RR），并使用 Review Manager（RevMan）[计算机程序]中的 95%置信区间（RR 值的α=0.05）估计二项数据的 RR。 Cochrane 协作，2020 年）。
纳入了 4 项比较 ETT 中使用和不使用桩核保留修复体的研究，共有 916 个修复体。总风险比为 2.16（95%CI：1.25-3.72）。
与不使用桩核保留的修复体相比，使用桩核保留的 ETT 显示出显著更低的失败率。需要进行精心设计的 RCT 来制定关于桩核保留修复体的临床方案。
