[A preliminary study of viral cross-transmission in dentistry].
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.


CONCLUSIONS
The instruments which have been sterilized should not be the main way of the cross-transmission of virus in dentistry.
