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.
