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.
