HIV may survive in dental tools

Associated Press - Friday, November 20, 1992


LONDON - The viruses that cause AIDS and hepatitis B can survive within dental tools that are washed with disinfectant but not heat-sterilized, posing a potential risk of disease transmission, according to a new study.

Experts said the findings of the study, to be published in Saturday's issue of The Lancet, are plausible, but the risk of catching AIDS from dental tools is probably very low. No such cases of have been reported.

However, finding pieces of HIV, the AIDS virus, in dental tools is "worrisome, mainly because the material was present in internal areas of the equipment that are not readily accessible to chemical germicides," said Dr. David Lewis, microbiologist at the University of Georgia.

The Food and Drug Administration wrote American dentists Sept. 28 advising that "reusable dental hand pieces and related instruments be heat-sterilized between patients."
