摘　　要：根管治疗指通过机械预备和化学方法去除根管内大部分感染物质及坏死组织,严密充填根管并封闭冠部,治疗已发生的牙髓及根尖周病变,并促进其愈合。冠方及根方的封闭性是影响根管治疗效果的主要原因,其中微渗漏的大小是评价充填物封闭能力的主要手段。目前,关于微渗漏的检测方法较多,但尚无统一的检测标准,且相同材料不同微渗漏检测方法的结果也不一致。准确评价微渗漏检测的效度是牙体牙髓病学评估封闭材料临床效果的研究重点。Root canal therapy is to remove most of the infection and necrotic tissue in the canal,fill the root canal and seal the crown tightly, treat the pulp and periapical lesions and promote healing through mechanical preparation and chemical methods.The sealing capability of coronal and apical is the main factor influencing the effect of root canal treatment. The size of microleakage is the main index to evaluate the sealing capability of sealing materials.At present,there are many microleakage detection methods,but are not standardized,which leads to different test results when different methods are adopted ,even for the same material being assessed. Evaluating the validity of microleakage accurately,has always been the research focus of endodontics to evaluate the clinical effect of the sealing materials.
