根尖封闭性评估方法研究进展

Research progress on methodologies for assessment of apical sealability

根管治疗中,根管充填的最终目的是严密封闭根管系统,以防止口腔致病菌在根管及根尖周组织定植、再感染。因此,根管充填后根尖封闭性是决定根管治疗成功与否的关键因素。当前文献中用于评估根尖封闭性能的方法多种多样,但各方法的评价标准不统一,使得实验结果难以获得较好的可比性。文章介绍了评估根尖封闭性的常用方法并就各方法的优缺点做一分析。

In root canal treatment,the ultimate aim of root canal obturation is to adequately fill the root canal system in order to prevent oral pathogens from colonizing and re-infecting the root and periapical tissues. Therefore,apical sealing ability of root canal fillings is the important factor that determines the success or failure of root canal treatment. Although there are various methodologies reported in the current literature for assessing apical sealability,they are not standardized,which make it difficult to compare the results. In this review,we have introduced the common methods for assessing apical sealability and critically analyzed the advantages and disadvantages of various methodologies.
