碘伏对牙科高速涡轮手机的腐蚀性观察

Observation on corrosion of lodophor to high speed turbine dental handpiece

目的 评价碘伏对牙科高速涡轮手机的腐蚀性。方法 采用肉眼和扫描电镜 (EPMA - 870 5电子探针 ) ,观察用碘伏及消毒灵分别浸泡手机轴承钢珠、轴承内部非金属材料和手术刀片后不同时间的表面腐蚀情况。结果 碘伏对金属腐蚀性很小 ,对非金属材料无影响。结论 采用碘伏用擦拭法或联合消毒法消毒手机 。

Objective To evaluate the corrosion of lodophor on handpice.Methods The surfaces of the steel balls,non-metal coming from handpieces and operation knives were soaked in lodophor and OlSAS solutions respectively. After different times all were observed by naked eyes and SEM. Results There was very little corrosion on metal and no corrosion on non-metal by using lodophor to sterilize the handpiece.Conclusion Lodophor exert little influence on handpiece.
