摘　　要：目的探讨脉动真空清洗消毒机对牙科手机清洗效果的影响。方法选取新购置的390支牙科高速手机作为研究对象,采用随机数字表法将其分为3组,即A组(130支,脉动真空清洗消毒机)、B组(130支,全自动热清洗消毒机)和C组(130支,手工清洗),比较3组牙科手机的清洗效果、管腔干燥效果和清洗时间。结果A组(100%)的清洗效果优于B组(89.2%)和C组(83.8%),B组的清洗效果优于C组,差异均有统计学意义(P<0.05);A组清洗时间(1.13 h)少于B组(1.80 h)和C组(2.60 h),B组清洗时间少于C组,差异均有统计学意义(P<0.05);而牙科手机管腔的干燥效果差异无统计学意义(P>0.05)。结论脉动真空清洗消毒机可有效提高牙科手机的清洗质量,缩短清洗时间,值得在临床广泛应用及推广。Objective To explore the effect of pulsating vacuum cleaning sterilizer on the cleaning quality of dental handpieces.Methods A total of 390 newly-purchased high-speed dental handpieces were covered in the study.By the random number table method,the handpieces were divided into three groups that were cleaned by different methods—Group A(n=130),pulsating vacuum cleaning sterilizer,group B(n=130),automatic thermal cleaning and disinfection machine,and group C(n=130),manual cleaning.The cleaning quality,internal cavity drying and the length of cleaning time of the three groups were compared.Results The cleaning quality of group A(100%)was better than those of groups B(89.2%)and C(83.8%)and the length of cleaning time of group A(1.13 h)was shorter than those of group B(1.80 h)and C(2.60 h),all showing significant differences(P<0.05).In addition,the cleaning quality of group B was better than that of group C and the length of cleaning time of group B was shorter than that of group C,all showing significant differences(P<0.05).However,there was no significant difference in the internal cavity drying effects between the three groups(P>0.05).Conclusions The pulsating vacuum cleaning sterilizer can effectively improve the cleaning quality of dental handpieces and shorten the cleaning time.Hence,it should be extensively applied and promoted in clinic service.
