摘　　要：目的探讨3种高效化学消毒剂对牙科常用小型器械的腐蚀性,为临床应用提供依据。方法按卫生部2002年版《消毒技术规范》"消毒剂对金属腐蚀性的测定"中所规定的测定方法和消毒剂使用方法,采用3种高效消毒剂(2%戊二醛、二氧化氯、氯氧三嗪)对4类材质14种小型器械进行消毒,并测定其腐蚀速率。结果3种消毒剂对牙科小型器械均有不同程度腐蚀,腐蚀速率的高低与消毒剂的浓度、浸泡时间和牙科小型器械的形状有直接关系,其中二氧化氯腐蚀性最强,氯氧三嗪次之,2%戊二醛腐蚀性最轻。结论临床消毒工作中要根据器械的不同材质,选择适宜的消毒剂,并严格控制消毒剂浓度和消毒时间,以减轻其对牙科小型器械的腐蚀。OBJECTIVE To evaluate the influence of three high-level chemical disinfectants for sterilization on cauterization of dental instruments. METHODS The measuring methods for disinfectants on cauterization of metal instruments,and usage indications for disinfectants followed Technical Standard for Disinfection published in 2002 by the Ministry of Health. Fourteen kinds of small instruments （grouped by 4 different metal materials） were analyzed on receipt and after sterilization by three high-level disinfectants （2% glutaraldehyde, chlorine dioxide, and symclosene）, using cauterization rate. RESULTS Three high-level disinfectants had different cauterization rates, the cauterization rate was affected by concentration of disinfectant, sterilizing time, and morphology of instruments. The cauterization of chlorine dioxide was the strongest, followed by symclosene （trichloroisocyanuric acid）, and then 2% glutaraldehyde. CONCLUSIONS In clinical sterilization, different materials of small instruments need proper disinfectants, concentration and sterilizing time for decreasing their cauterization.
