摘　　要：目前国内有机溶剂仍广泛应用于根管再治疗中,主要用于溶解已充填需再治疗根管内的牙胶和根充糊剂,提高根管再治疗效率相关研究也证明了其杀菌特性。但有机溶剂有一定毒性,也存在改变根管壁理化特性不利于去除管壁玷污层,甚至应用不当还会带来化学性的根尖周炎、牙槽骨的吸收等弊端。本文综述了根管治疗中有机溶剂的应用及相关研究进展,为充分的了解其利与弊,合理的应用有机溶剂提供参考依据。At present the organic solve nt that can dissolve gutta-percha and paste filler is still widely used in the root canal retreatment in China. Although the solvent help doctors work efficiently and kill the bacteria in the canals, it can also lead to the chemical periapical periodontitis,the absorption of the alveolar bone and the changing of the root canal physical and chemical conditions.In this article,we summarize the application and study of tethe organic solvent to hope that it can help us use the solvent reasonably.
