Surveillance of viral contamination of invasive medical instruments in dentistry.
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.


CONCLUSIONS
Though massive virus contamination of invasive medical instruments in dentistry has been reduced to a low level, the occurrence of contamination still remains.
