Abstract
Exceptions have occurred to the generally reported high prevalence of viral hepatitis in dentists. Thus a recent questionnaire survey (1) indicated a low risk of hepatitis in dental professionals in Norway. The present supplementary study was based on frequencies of serological markers of viral hepatitis and disclosed an exposure rate to hepatitis B insignificantly higher than that of the general population. The frequency of antibody to hepatitis A virus was equal to that of the general population.
