摘要/Abstract

摘要： 根管治疗术是牙髓病和根尖周病常见的治疗方法,术后严密封闭根管系统可以切断根尖周组织再感染途径,确保根管治疗的远期疗效。如果根管封闭性欠佳则容易引起病原微生物及其代谢产物经过封闭材料与根管壁之间的微渗漏(包括冠方和根尖区)使根尖周组织再感染导致根管治疗失败。可见严密封闭根管系统至关重要。目前检测根管封闭性的方法较多,但关于根管系统封闭性的影响因素和检测根管封闭性的方法尚缺乏较系统的阐述。本文将影响根管封闭性的因素及检测和评价根管封闭性的方法进行综述,为检测根管充填质量和评估远期疗效提供借鉴和参考。

Abstract: Root canal therapy is the main treatment method for common oral diseases such as pulp disease and periapical disease. A hermetic coronal sealing of canal system during the root canal treatment can avoid the injection of the periapical tissue and ensure the success of root canal treatment in the long term. Endodontic failure may be caused due to incomplete obturation, including penetration of the microbial and their metabolites through the gap between filling materials and the root canal system. Therefore, tightly sealed root canal system is essential for long-term success. There are many factors that affect the root canal filling sealability and its detection methods have not been systemically described. This is a review about the reason of microleakage and the relationship between complete obturation and the long-term success of root canal treatment and the influenced factors of apical sealing and coronal restorations.
