压力蒸汽灭菌对口腔高速手机乙型肝炎表面抗原的消毒效果

The disinfection effect of pressure steam sterilization on hepatitis B surface antigen in dental high speed handpiece

目的探讨压力蒸汽灭菌对口腔高速手机乙型肝炎表面抗原（HBsAg）的消毒效果。方法将乙肝患者使用过的污染口腔科高速手机30把随机分为A、B、C3组，A组采用2％戊二醛浸泡消毒，B组采用消毒剂擦拭法消毒，C组采用压力蒸汽灭菌消毒，采用酶联免疫吸附法检测3种方式消毒后的口腔科高速手机HBsAg的阳性情况。结果乙肝患者使用过的口腔科高速手机的HBsAg的阳性率为30．0％，A组和C组中HBsAg均为阴性，B组中HBsAg的阳性率为10．0％。A组和C组中无细菌生长，B组细菌超标率为10．0％。结论压力蒸汽灭菌对1：7腔高速手机的消毒效果较好，不容易造成环境污染，是目前较为理想的消毒口腔高速手机的方法。

Objective To investigate the disinfection effect of pressure steam sterilization on hepatitis B surface antigen in dental high speed handpiece. Methods A total of 30 polluted high - speed handpiece of stomatology department by hepatitis B patients were ran- domly divided into A, B, C three groups, group A was used 2% glutaraldehyde immersion disinfection, group B was used disinfectant disin- fection method, group C was used pressure steam sterilization, The positive rate of HBsAg in high - speed mobile phone by 3 ways of disin- fecting was detected by ELISA method. Results The positive rate of HBsAg was 30% in dental high speed handpiece, HBsAg were negative between group A and group C, the positive rate of HBsAg was 10% in group B. No bacterial growth in group A and C group, bacteria exceed the standard rate was 10% in group B. Conclusions The disinfection effect of pressure steam sterilization in dental high speed handpiece is good; it does not cause environmental pollution and it is a ideal method in disinfection of dental high - speed handpiece.
