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 ( =130), pulsating vacuum cleaning sterilizer, group B ( =130), automatic thermal cleaning and disinfection machine, and group C ( =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 ( <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 ( <0.05). However, there was no significant difference in the internal cavity drying effects between the three groups ( >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.
目的
探讨脉动真空清洗消毒器对牙科手机清洗质量的影响。
方法
本研究共纳入390支新购高速牙科手机。采用随机数字表法将手机分为三组，分别采用不同方法清洗——A组（ =130），使用脉动真空清洗消毒器；B组（ =130），使用自动热清洗消毒机；C组（ =130），采用手工清洗。比较三组的清洗质量、内腔干燥情况及清洗时间长短。
结果
A组的清洗质量（100%）优于B组（89.2%）和C组（83.8%），且A组的清洗时间（1.13小时）短于B组（1.80小时）和C组（2.60小时），差异均有统计学意义（ <0.05）。此外，B组的清洗质量优于C组，且B组的清洗时间短于C组，差异均有统计学意义（ <0.05）。然而，三组在内腔干燥效果方面差异无统计学意义（ >0.05）。
结论
脉动真空清洗消毒器能有效提高牙科手机的清洗质量并缩短清洗时间。因此，应在临床服务中广泛应用和推广。
