脉动真空清洗消毒机对牙科手机清洗效果的影响

Effect of Pulsating Vacuum Cleaning Sterilizer on the Cleaning Quality of Dental Handpieces

摘要

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。

Abstract:
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.
