根管治疗失败,需要重作根管治疗时,常用氯仿溶解牙胶尖,再用扩孔钻和锉去除。氯仿是二甲苯、苯精和桉油等有机溶剂中溶解力最强最常用的溶剂。但因其对人体的毒性、刺激性和动物实验证明其有致癌性。日本厚生省已停止含氯仿药品的制售。 Root canal treatment fails, you need to re-root canal treatment, often dissolved in chloroform gutta-percha points, re-use reamer and file removal. Chloroform is the most commonly used solvent for strongest solvency in xylene, benzene and eucalyptus oils. But because of its toxicity to the human body, irritation and animal experiments have proved its carcinogenicity. Japan's Ministry of Health and Welfare has stopped the sale of chloroform-containing drugs.
