OBJECTIVE
To investigate the viral contamination of invasive medical instruments in dentistry and to provide health administrative institutions with surveillance data.
METHODS
Sterilized samples were randomly collected from the department of dentistry to detect HBV-DNA, HCV-RNA, HIV-RNA and HBsAg.
RESULTS
Of the invasive medical instruments that were sterilized with 2% glutaraldehyde, one of the samples was positive for HBV-DNA, and another sample was positive for HBsAg.
CONCLUSION
Though massive virus contamination of invasive medical instruments in dentistry has been reduced to a low level, the occurrence of contamination still remains.
目的
调查牙科侵入性医疗器械的病毒污染情况，为卫生行政机构提供监测数据。
方法
从牙科随机采集已消毒样本，检测乙肝病毒脱氧核糖核酸（HBV-DNA）、丙型肝炎病毒核糖核酸（HCV-RNA）、人类免疫缺陷病毒核糖核酸（HIV-RNA）及乙肝表面抗原（HBsAg）。
结果
在使用2%戊二醛消毒的侵入性医疗器械中，有一份样本的HBV-DNA呈阳性，另一份样本的HBsAg呈阳性。
结论
尽管牙科侵入性医疗器械的大规模病毒污染已降至低水平，但污染情况仍有发生。
