摘　　要：目的探讨循环风空气消毒机对口腔牙周病科空气消毒效果,以便为动态工作环境提供一种有效的消毒方法。方法采用随机对照试验法,2015年6月—7月选择2间面积为300m2牙周病科诊室,分别采用循环风空气机消毒法与紫外线灯消毒法。比较两种方法空气消毒前与消毒后即刻(0min)及消毒后工作时间30min、60min、90min、120min空气菌落数情况。结果紫外线灯消毒法与循环风空气机消毒法消毒前、消毒后即刻(0min)两组组内平均菌落数比较,差异具有统计学意义(t=-389.46,P<0.001;t=-515.16,P<0.001),消毒后均低于消毒前;消毒前、消毒后即刻(0min)两种消毒方法组间平均菌落数比较,差异具有统计学意义(t=6.89,P<0.001;t=13.30,P<0.001),其均数差值及其95%CI分别为9.08(6.46,11.70)与9.50(8.08,10.92),可能没有实际临床意义。两种消毒方法组内不同时间点空气平均菌落数不同,Tukey法两两比较均有差异(均P<0.001),消毒后不同工作时间点(30min、60min、90 min、120min)两种消毒方法空气平均菌落数不同(F=4520.75,P<0.001),循环风消毒机消毒法菌落数均低于紫外线灯法。结论牙周病科诊室在人员工作期间空气消毒,采用循环风空气机消毒法的消毒效果优于紫外线灯法。Objective To evaluate the air disinfection effects of circulating air disinfectors in the periodontal department.Methods During June and July 2015,two periodontal treatment rooms(300 m2 for each room)were disinfected by circulating air disinfectors and ultraviolet lights,respectively.The number of colony-forming unit(CFU)in the air was evaluated before and after disinfection at 0 min,30 min,60 min,90 min,and 120 min under the working condition.Results There was a significant reduction of CFU number after disinfection(0 min)in both circulating air disinfector group and ultraviolet light group(t=-389.46,P<0.001;t=-515.16,P<0.001).The number of CFU before and after disinfection(0 min)was both significantly different between groups(t=6.89,P<0.001;t=13.30,P<0.001).But,the 95%CI of CFU number before disinfection was 9.08(6.46,11.70),which was considered to be of no significance clinically.The number of CFU after disinfection under the working condition was varied between the two groups at different time points(30 min,60 min,90 min,and 120 min)with significant differences(F=4520.75,P<0.001),which also differed significantly in both groups(Tukey test,P<0.001).The circulating air disinfectors had a fewer number of CFU.Conclusion The air disinfection effect of circulating air disinfectors is better than ultraviolet light in the periodontal department.
