摘要
目的评价氧化电位水(EOW)对口腔器械污染菌的消毒效果。方法以临床使用后的扩大针和高速手机为对象,扩大针分别用EOW和2%戊二醛消毒,手机分别用EOW消毒和高温高压灭菌,于消毒前、后采样,细菌培养,菌落计数。结果对扩大针消毒10 min,两种消毒剂的消毒合格率均达100%,对手机采用两种消毒方法均可全部杀灭其表面和冷却水管内污染菌,但EOW组不采用内部冲洗时,手机内部冷却水管内仍有大量细菌生长。结论EOW消毒可达与2%戊二醛浸泡消毒、高温高压蒸汽灭菌同样可靠的消毒效果。
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.
