摘要
目的观察增效型过氧化氢消毒纸巾对超声洁牙机手柄消毒效果。方法分别采用增效型过氧化氢消毒纸巾与含氯消毒剂对超声洁牙机手柄消毒,使用TPC半定量细菌培养载片和ATP荧光检测仪对消毒前后的细菌数与相对光单位值(RLU)进行测定。结果超声洁牙机手柄消毒前后菌落数有统计学意义(P<0.01),擦拭消毒后,两种消毒方法消毒效果无统计学意义(P=0.90);增效型过氧化氢消毒纸巾消毒前后ATP值有统计学意义(P<0.01)。结论两种消毒剂消毒效果无差异,但与含氯消毒剂相比,增效型过氧化氢消毒纸巾与洁牙机手柄材料兼容性好,无腐蚀、安全性较高,清洁与消毒效果理想,适合临床上使用。
Objective To observe the disinfection effect of synergistic hydrogen peroxide disinfectant wipes of the ultra- sonic scaler handles. Methods Ultrasonic scaler handles were disinfected by synergistic hydrogen peroxide disinfectant wipes and chlorine - containing disinfectants, the number of bacterial colony was counted before and after disinfection by u- sing TPC semi quantitative bacterial culture slide. Relative light unit values （ RLU ） was measured by ATP fluorescence detector. Results There was statistically significant difference in the bacterial counts and RLU before and after the disin- fection of the ultrasonic scaler handle（ P 〈 0. 01 ）, the difference of the effect of two disinfectants had not statistically signif- icant （P = 0. 90）. Conclusion There is no difference in the disinfection effect between the two disinfectants. But compared with the chlorine - containing disinfectant, synergistic hydrogen peroxide disinfectant wipes is with the high safety, good material compatibility, so it is an ideal choice for the disinfection of the ultrasonic scaler handles.
