拔牙术中乙型、丙型肝炎病毒污染的调查及对策

目的对常规拔牙术中乙型、丙型肝炎病毒污染情况进行调查，进一步控制医源性感染。方法随机抽取500例门诊拔牙患者的术中止血棉球，分别浸入2个（A、B）盛有1ml生理盐水的无菌试管内，其浸出液分别用两种方法进行肝炎病毒检测。结果A组（HBsAg）检测到40例阳性（8．00％），B组（IgG）检测到12例阳性（2．40％），HBsAg和IgG检测到A组和B组同时阳性2例（0．40％）；500例门诊拔牙患者中检测到被肝炎病毒感染的有54例，占调查总人数的10．8％。结论口腔门诊乙型、丙型肝炎感染率很高，迫切要求口腔医务工作者要加强职业防护，有效防治肝炎病毒通过口腔科诊疗传播。
