摘　　要：目的观察比较口腔科门诊牙椅旁高频接触物体表面污染程度的动态变化情况,为口腔科门诊椅旁物表消毒管理提供参考依据。方法选取中日友好医院口腔医学中心牙周科、口腔全科、正畸科的椅旁操作小桌和治疗车台面作为调查对象,分别在消毒后即刻和消毒后1、2、3 h使用生物荧光检测仪对指定区域进行涂抹采样,每个位点连续采集观察5个工作日。结果受检物体表面消毒后即刻采样合格率100%,消毒后1、2、3 h的采样合格率依次为26.7%(8/30)、23.3%(7/30)、13.3%(4/30),均污染超标且各时间点采样合格率差异有统计学意义(χ2值为59.155,P<0.05)。消毒后1、2、3 h,椅旁桌采样合格率依次为26.7%(4/15)、20.0%(3/15)、13.3%(2/15),治疗车采样合格率依次为26.7%(4/15)、26.7%(4/15)、13.3%(2/15),均污染超标且各位点采样合格率差异无统计学意义(χ2值为0.034,P>0.05)。结论口腔科门诊应重视椅旁高频操作台面的物表消毒管理,并根据污染变化情况合理调整消毒频率,以确保椅旁操作台面的物表卫生符合规范要求。Objective To observe and compare the dynamic changes of contamination of high-frequency contact surfaces near dental chairs in outpatient department of stomatology,so as to provide reference for the disinfection management of the surface contamination near dental chairs in outpatient department of stomatology.Methods The chair-side operating tables and treatment vehicle tables in the Department of periodontology,general stomatology and orthodontics of Stomatology center of our hospital were selected as the subjects of investigation.Biofluorescence detector was used to smear and sample the designated areas immediately after disinfection and 1 hour,2 hours and 3 hours after disinfection respectively.Each site was collected and observed for 5 working days.Results The qualified rate of sample was 100%immediately after disinfection,and the contamination exceeded the standard one hour,two hours and three hours the qualified rate of sampling was 26.7%(8/30),23.3%(7/30)and 13.3%(4/30)after disinfection.There was a significant difference in the qualified rate of sample at each time point(χ2 value was 59.155,P<0.05).One hour,two hours and three hours after disinfection,the contamination of chair-side tables the qualified rate of sampling was 26.7%(4/15),20.0%(3/15)and 13.3%(2/15)and treatment vehicles the qualified rate of sampling was 26.7%(4/15),26.7%(4/15)and 13.3%(2/15)exceeded the standard and there was no significant difference in the qualified rate of sample at each point(χ2 value was 0.034,P>0.05).Conclusion The outpatient department of stomatology should pay attention to the disinfection management of high-frequency contact surfaces near dental chairs,and adjust the disinfection frequency reasonably according to the change of pollution to ensure the surface hygiene and meets the standard requirements.
