摘    要:目的比较两种清洗剂清洗牙科钻针的效果。方法将临床使用后的600支污染严重的牙科钻针随机分为两组,分别采用多酶和碱性清洗剂进行清洗。通过20倍台式显微镜下观察及清洗前后三磷酸腺苷(ATP)相对发光值(RLU)的测定判断清洗效果。结果显微镜下观察多酶清洗剂清洗合格率为73.0%,碱性清洗剂清洗合格率为71.7%。清洗不合格的部位主要是钻针的颈部。RLU值的测定结果为:多酶清洗剂清洗的有效率为98.7%,碱性清洗剂清洗的有效率为99.1%。两种清洗剂清洗前后效果比较,差异有统计学意义(P<0.01),组间清洗后效果比较,差异无统计学意义(P>0.05)。结论多酶清洗剂和碱性清洗剂用于污染牙科钻针的清洗均有效果,但碱性清洗剂价格便宜,建议在临床使用。

Abstract:Objectives To compare the effect of two types of cleaning agents on dental burs.Methods Totally 600 contaminated dental burs were randomly assigned to two groups washed by multienzyme cleaner and alkaline cleaning agent,respectively.The washing effect was determined by the value of relative light unit(RLU) for the measurement of adenosine triphosphate(ATP) and macroscopic observation with 20-times microscope.Results The qualified rates measured by macroscopic observation with 20-times microscope in multienzyme cleaner group and alkaline cleaning agent group were 73.0% and 71.7%,respectively.The most frequently contaminated part was the neck of the dental burs.The qualified rates measured by RLU value in multienzyme cleaner group and alkaline cleaning agent group were 98.7% and 99.1%,respectively.There was no significant different in the cleansing effect between the two groups(P>0.05).Conclusion Multienzyme cleaner and alkaline cleaning agent are both effective to wash dental burs.Alkaline cleaning agent is recommended for the economic reason.
