近几年许多学者提出产黑色素类杆菌是牙髓、牙周及其化脓性感染的主要致病菌。国内用酚醛树脂液对口腔厌氧菌的处理研究尚未见报道,我们在临床上经7年用酚醛树脂液充填根管3520例,并将酚醛树脂液对口腔厌氧菌的抑菌试验和动物的毒性进行了初步的研究,现将结果报道如下。材料与方法一、材料:1.酚醛树脂液配方如下:A:38～40%甲醛溶液10ml,B:间苯二酚(雷锁辛)5.2g,氢氧化钠1.2g,蒸馏水5ml。使用时按A:B为1.2配制(临床使用加碘仿少许,便于 X 线观察)。
In recent years, many scholars have proposed the production of melanobacteria is the pulp, periodontal and purulent infection of the main pathogens. Domestic research on the treatment of oral anaerobic bacteria with phenolic resin has not been reported yet. We have clinically applied 3520 cases of root canal filling with phenolic resin solution for 7 years and tested the antibacterial activity of phenolic resin against oral anaerobic bacteria and animal The toxicity of a preliminary study, the results are reported below. Materials and methods 1. Materials: 1. The solution of phenolic resin liquid is as follows: A: 10ml of 38-40% formaldehyde solution, B: 5.2g of resorcinol, 1.2g of sodium hydroxide and 5ml of distilled water. When used by A: B 1.2 preparation (clinical use of iodoform imitation, easy to X-ray observation).
