Abstract:
OBJECTIVE To evaluate the disinfecting effect of electrolyzed-oxiding water(EOW) on dental(instruments) contaminated after clinical operation.METHODS Use K-reamer and high-speed handpiece as objects of test.(K-reamers) were disinfected by EOW and 2% glutaraldehyde for 5min and 10min,respectively.And(handpieces) were disinfected by EOW and autoclave sterilization,respectively.The samples were collected from each(K-reamer) and each handpiece′surface and its water-canal before and after disinfection.The samples were done germiculture.RESULTS Disinfecting K-reamer for 10min,the disinfection rate of two disinfectants(EOW and 2%(glutaraldehyde)) were both 100%.Disinfecting handpiece with EOW(by surface-wiping,immersing and rinsing the water-canal)or autoclaving sterilization,the disinfection rate of EOW and 2%glutaraldehyde were both 100%.(Disinfecting) handpiece with EOW(by surface-wiping,immersing and rinsing the water-canal) or autoclaving(sterilizaion),the bacteria contaminated on handpiece′s surface and in the water-canal could all be killed,while(disinfecting) handpieces with EOW only by surface-wiping,and immersing,in the water-canal there were still a lot of bacteria.CONCLUSIONS The disinfecting effect of EOW is reliable and safe compared with 2%(glutaraldehyde) and autoclave sterilization.
