ABSTRACT
OBJECTIVE To investigate the disinfection efficacy of dental high-speed hand-pieces contaminated by HBV with the method of pressure steam sterilizer.METHODS Taking 50 oral clinical patients randomly,and three group-samples which included saliva,hand-pieces contaminated by clinical operation and disinfected by pressure steam sterilizing were collected,then the samples were detected HBsAg and HBV DNA,respectively.RESULTS There were 95% of the saliva samples being HBsAg positive,the positive rate of the high-speed hand-pieces contaminated by clinical operation was lower than the saliva samples,and the positive rate of the hand-piece disinfected by pressure steam sterilizing was the lowest.HBV DNA was undetectable in the sample before or after disinfected hand-pieces used in patients′ saliva which HBsAg s/co value higher than 5.0.CONCLUSIONS Pressure steam sterilizing is effective to reduce the contaminated HBV on hand-pieces,but the biology test should be taken to demonstrate whether the complete sterilizing is achieved.
