The efficacy of a steam disinfection method for the processing of used instruments in dental practice was tested with 274 high-speed turbines and handpieces. The instruments treated with streaming steam were both taken out of the dental practice of treatment and artificially contaminated with five different test-microorganisms (E. coli, P. aeruginosa, S. aureus, E. faecium, C. albicans) and different concentrations of serum (1%, 10%, 20%). In spite of the narrow channels of these instruments a microbial reduction of more than 5 log10 steps could be achieved in all cases. Thus dental high-speed turbines and handpieces can reliably be disinfected with streaming steam.
使用274台高速涡轮机和牙钻手机,测试了一种蒸汽消毒方法在牙科诊所处理用过器械的效果。用流动蒸汽处理过的器械既取自牙科治疗诊所,又人工污染了五种不同的测试微生物(大肠杆菌、铜绿假单胞菌、金黄色葡萄球菌、粪肠球菌、白色念珠菌)以及不同浓度的血清(1%、10%、20%)。尽管这些器械的通道狭窄,但在所有情况下都能实现超过5个对数10级的微生物减少。因此,牙科高速涡轮机和牙钻手机可以通过流动蒸汽可靠地进行消毒。
