Survey of hepatitis B exposure and vaccination in volunteer dentists.

Hepatitis B virus (HBV) serum markers were surveyed at the 1983, 1984, and 1985 ADA annual sessions, beginning the first year after the hepatitis B vaccine became available to the dental profession. Results from serum samples from 2,776 dentists in regard to increase in vaccination against HBV and the incidence of natural exposure to HBV during the 2-year study are discussed; data addressing the development of surface antibody after administration of the three-inoculation vaccine are presented.
