Non-vital teeth usually exhibit substantial loss of coronal and radicular tooth structure, and use of posts after root canal treatment is controversial. This review examined whether placement of posts influences clinical behavior and survival probability of endodontically treated teeth (ETT).
An electronic search, without time restrictions, for publications written in English was undertaken in PubMed, Scopus, and Web of Science. Terms related to four main components (endodontically treated teeth, fixed prosthesis, post restoration, and survival rate) were used for the database search strategies.
57 studies met the inclusion criteria and were included in the qualitative analysis. Of the publications chosen for qualitative analysis, 17 clinical studies (11 prospective and 6 retrospective studies) were found to be suitable for quantitative analysis. These studies included 7,278 patients (7,330 ETT), with a mean age ± standard deviation (SD) of 45.46 ± 12.1 years. There was a statistically significant difference in survival rate between ETT with or without posts (P < 0.001).
As compared with teeth with no posts, post placement on ETT may improve clinical performance and survival probability of endodontically treated teeth.
非活力牙通常表现出大量的冠部和根部牙体结构丧失，并且根管治疗后使用桩核存在争议。本综述检查了桩核的放置是否会影响根管治疗牙（ETT）的临床行为和生存概率。
在 PubMed、Scopus 和 Web of Science 中进行了无时间限制的英文文献电子检索。使用与四个主要组成部分（根管治疗牙、固定修复体、桩核修复和生存率）相关的术语制定了数据库搜索策略。
57 项研究符合纳入标准并纳入了定性分析。在选择进行定性分析的出版物中，发现 17 项临床研究（11 项前瞻性研究和 6 项回顾性研究）适合进行定量分析。这些研究包括 7278 名患者（7330 颗 ETT），平均年龄 ± 标准差（SD）为 45.46 ± 12.1 岁。有桩核的 ETT 和无桩核的 ETT 的生存率有统计学显著差异（P < 0.001）。
与无桩核的牙齿相比，桩核的放置可能会改善根管治疗牙的临床性能和生存概率。
