【摘要】 目的　对口腔科的病毒交叉感染情况进行初步研究。方法　分别应用 5种不同的消毒方案 ,对乙型肝炎病毒 (HBV)、丙型肝炎病毒 (HCV)阳性血清污染的口腔科器械进行消毒处理 ,分别检测消毒前后HBsAg、HBV DNA和抗 HCV、HCV RNA的情况。结果　 5种消毒方法均能有效清除所污染病毒的特异性蛋白 (HBsAg、抗 HCV)和核酸 (HBV DNA、HCV RNA)。结论　消毒后的器械不应该是口腔科病毒交叉感染的主要途径更多还原

【Abstract】 Objective To research the viral cross transmission of a DNA virus (HBV) and a RNA virus (HCV) in dentistry Methods Five plans were designed to sterilize the oral instruments that had been infected with HBV or HCV positive serum HBsAg, HBV DNA , anti HCV, HCV RNA were detected before and after sterilization Results All methods could effectively clean the specific proteins (HBsAg/anti HCV) and nucleic acids (HBV DNA/HCV RNA) of the infected virus Conclusion The instruments which have been sterilized should not be the main way of the cross transmission of virus in dentistry更多还原
