牙体充填材料的微漏是关系到牙体、牙髓治疗成败的重要因素之一。牙体充填物边缘与洞壁间的微漏可引起充填物边缘染色、牙髓刺激症状、继发龋,甚至充填物松动脱落等一系列临床问题。根管充填材料与根管壁间的微漏增加了根管系统再感染的机会,最终可导致根管治疗失败。为研究充填材料的边缘密封性,学者们设计了诸多的微漏检测法,本文拟从实用的角度对有关方法进行 Micro-leakage of dental filling material is one of the important factors that affect the success of tooth and pulp treatment. Microleakage between the edge of the dental filling and the wall of the cavity can cause a series of clinical problems such as edge staining of the filling, pulp irritation, secondary caries, and even loosening of the filling. Microleakage between the root canal filling material and the root canal wall increases the chance of re-infection of the root canal system, which can eventually lead to failure of root canal therapy. In order to study the edge sealing of filling materials, scholars have designed a lot of micro-leakage detection method, this article from the practical point of view of the relevant methods
