【摘要】 目的探讨过氧化氢低温等离子体灭菌法应用于牙科手机灭菌。方法240支牙科手机按照注油方式和包装方式不同,分为8组,经强生STERRAD 100S过氧化氢低温等离子体灭菌器灭菌后,通过无菌检验检测灭菌效果,并进行转速检测和外观检查。结果自动注油组灭菌后的牙科手机在4种包装形式下,无菌检验均无菌生长,灭菌效果可靠;牙科手机经10次过氧化氢等离子体灭菌循环,转速无明显下降,外观完好,无明显氧化现象。结论过氧化氢低温等离子体灭菌牙科手机灭菌效果可靠,未见牙科手机机械性能损耗。更多还原

【Abstract】 OBJECTIVE To investigate the application of low temperature hydrogen peroxide gas plasma sterilization in dental handpieces.METHODS Totally 240 pieces dental handpieces were divided into 8 groups in accordance with different ways of oiling and package,sterilized by Johnson STERRAD 100S low temperature hydrogen peroxide gas plasma sterilizer,and then inspected by sterility testing,rotational speed and appearance observation.RESULTS The result of sterility testing of dental handpieces in auto oiling group with 4 types of packages was negative,and the sterilization effect was reliable.After 10 cycles of low temperature hydrogen peroxide gas plasma sterilization,the rotational speed of dental handpieces had no obvious decline and the appearance was quite intact without any corrosion.CONCLUSIONS The sterilization effect is reliable and the damage caused by low temperature hydrogen peroxide gas plasma sterilization on dental handpieces is not found.更多还原
