摘　　要：目的 :了解口腔科医务人员常规治疗病人后手部病原微生物污染状况。方法 :对口腔内科和外科的医生和护士常规治疗病人脱去手套后洗手前后采样,并进行菌落计数和细菌分型鉴定。结果:口腔外科医生和护士治疗病人脱去手套未洗手前,细菌菌落数(Log10CFU)分别为:1.43±0.71、1.67±0.47,口腔内科医生和护士分别为1.62±0.48、1.86±0.52;洗手后细菌菌落数在0.40±0.22~0.45±0.14 Log10CFU之间,与以上四组相比有显著差异。细菌分型鉴定常见的病原菌为表皮葡萄球菌、金黄色葡萄球菌和大肠杆菌等。结论:口腔科医务人员常规治疗病人后手部病原微生物污染严重,需加强手卫生管理,从而有效降低通过医务人员手传播医院感染的风险。Objective：The present study was undertaken to find out the prevalence of bacterial contamination in hands of heahheare workers of a stomatology hospital. Methods：Five fingertip imprints of dominant hand of 98 health care workers （HCWs）in stomatology hospital were sampled to establish the average bacterial count before and after hand hygiene action using. Isolated microorganisms were identified using Gran＇s stain. Results：Hand contamination after patient care and before hand hygiene procedures was higher compared with after hand hygiene, the difference was significant （P ≤0.05）. Overall, Gram positive organisms was the predominant organism in hand of HCWs in stomatology hospital. Conclusion：Hand hygiene should be considered as the standard of care for every HCWs in stomatology department.
