目的:本系统综述的主要目的是评估保留颈周牙本质(PCD)是否会增加经牙髓治疗的恒牙的抗骨折能力。
方法:两名独立审稿人对2007年(2007年1月1日)至2023年(31月5日23日)的所有已发表的研究进行了全面审查,因为PCD的概念于2007年首次出现在文献中。在多个电子数据库引擎中进行了搜索:PubMed,Scopus,EBSCO(牙科和口腔健康科学),WebofSciences(WOS),科克伦,谷歌学者和开放灰色,Ovid和Shodhganga,除了交叉引用和手工搜索。根据一定的纳入和排除标准选择文章,which,简而言之,是以英文发表的基于实验室的研究,评估PCD对牙髓治疗的恒牙后牙的抗骨折性的影响。使用域,例如样本量,样品尺寸,和对照组作为质量评估标准,对选定的文章进行评估,并根据它们的偏见风险将它们分类为低,中度,和高。使用随机效应建模在P<0.05的显著性水平下进行荟萃分析。
结果:总共从10个不同的电子搜索数据库和手工搜索中检索到6,043项研究,但在删除重复项并应用资格标准后,仅选择了12项基于实验室的研究.在纳入的12项研究中,9项研究显示偏倚风险低,3项研究显示偏倚风险中等.两项研究显示了相关的荟萃分析数据,两项研究之间观察到的差异在统计学上不显着。
结论:根据研究结果,有证据支持PCD保留为牙髓治疗的后牙提供抗骨折能力.
结论:保守的腔准备和避免使用高锥度器械的做法通过保留PCD增加了牙齿的抗断裂能力。如何引用这篇文章:HaridossS,RajendranM,SwaminathanK,etal.颈管周围牙本质对根管治疗后恒牙骨折阻力影响的系统评价和Meta分析.JConempDentPract2024;25(4):372-385。
OBJECTIVE: The main aim of this present systematic review is to evaluate if the preservation of pericervical dentin (PCD) increases the fracture resistance of endodontically treated permanent posterior teeth.
METHODS: Two independent reviewers conducted a comprehensive review of all published studies from 2007 (1/1/2007) to 2023 (31/5/23) since the concept of PCD first appeared in the literature in 2007. Searches were conducted in multiple electronic database engines: PubMed, Scopus, EBSCO (Dentistry and oral health sciences), Web of Sciences (WOS), Cochrane, Google Scholar and Open Grey, Ovid and Shodhganga, in addition to cross-references and hand search. Articles were chosen according to a certain inclusion and exclusion criteria, which, in brief, are laboratory-based studies published in English that assess the impact of PCD on fracture resistance of endodontically treated permanent posterior teeth. Using domains, such as sample size, sample dimensions, and control group as quality assessment criteria, evaluated the selected articles and classified them according to their risk of bias into low, moderate, and high. A meta-analysis was conducted using random effects modeling at a significance level of p < 0.05.
RESULTS: A total of studies 6,043 were retrieved from 10 different electronic search databases and hand searches, but only 12 laboratory-based studies were selected after removing duplicates and applying the eligibility criteria. Of the included 12 studies, nine studies showed low risk of bias and three studies showed moderate risk of bias. Two studies showed related data for meta-analysis, the difference observed between the two studies is statistically non-significant.
CONCLUSIONS: Based on the results of the study, there is evidence to support that PCD preservation offers fracture resistance to the endodontically treated posterior teeth.
CONCLUSIONS: The practice of conservative cavity preparation and avoiding the usage of instruments with high taper increases the fracture resistance of the tooth by retaining the PCD.
