成功的根管治疗依赖于消毒技术。牙胶尖是最常使用的根管充填料。它不能用高压、烤箱等物理方法消毒。本文研究目的是找出一种实用的有效牙胶尖表面消毒法,消毒药物尽可能是在牙科中常用的根管杀菌冲洗剂。作者先通过细菌培养,获得各种细菌菌落的混悬液,然后将牙胶尖浸入细菌混悬液里接种。接种后的牙胶尖浸入装有5ml试验用的杀菌溶液的烧杯里5分钟,再将这些表面消过毒的牙胶尖放在作细菌培养的肉汤里,于37℃培养7天。在1、2和7天后
Successful root canal therapy relies on disinfection techniques. Gum tip is the most commonly used root canal filling material. It can not be sterilized by high-pressure, oven and other physical methods. The purpose of this study is to find out a practical and effective disinfection of dentin surface disinfection drugs as far as possible in the dental root canal sterilization rinse agent. The authors first obtain a suspension of various bacterial colonies by bacterial culture, then inoculate the tip of the gum into the bacterial suspension. The inoculated gutta percha tip was immersed in a beaker containing 5 ml of the test bactericidal solution for 5 minutes, and the surface-sterilized gutta-percha was placed in a bacterial broth and incubated at 37 ° C for 7 days. After 1, 2 and 7 days
