牙科手机干燥方法对油包发生率的影响

Study on the Selection of Drying Methods and the Incidence of Oil Pocket in Dental Handpieces

目的探讨3种牙科手机干燥方法在压力蒸汽灭菌中的应用效果,为牙科手机干燥灭菌提供技术指导。方法选取2022年6—10月医院科室中可正常使用的1200支牙科手机,注油并利用气枪吹干后,以随机数字表法分为垂直静置组(400支)、负压真空干燥柜干燥组(400支)与普通干燥柜干燥组(400支)。比较3组油包发生率。结果普通干燥柜干燥组油包率低于垂直静置组、负压真空干燥柜干燥组,差异有统计学意义(P<0.05)。结论使用普通干燥柜干燥牙科手机能够显著降低油包发生率。

Objective To explore the application effects of three drying methods for dental handpieces in pressure steam sterilization,and provide technical guidance for drying and sterilization of dental handpieces.Methods 1200 dental handpieces that can be used normally in hospital departments from June to October 2022 were selected,oiled and dried with an air gun.They were randomly divided into a vertical standing group(400 pieces),a negative pressure vacuum drying cabinet drying group(400 pieces),and a regular drying cabinet drying group(400 pieces)using a random number table method.Compare the incidence of oil pockets among three groups.Results The oil inclusion rate in the ordinary drying cabinet drying group was lower than that in the vertical static group and the negative pressure vacuum drying cabinet drying group,and the difference was statistically significant(P<0.05).Conclusion Using a regular drying cabinet to dry dental handpieces can significantly reduce the incidence of oil stains.
