[Seroepidemiology of hepatitis B markers in dentists in Ille-et-Vilaine].

In June, 1982 a questionnaire concerning a serological and epidemiological study of hepatitis B markers was mailed to the 421 private dentists in the Ille-et-Vilaine department, France. One hundred and eighty-nine dentists (49%) filled the questionnaire, and 163 (38.2%) were investigated for HBs antigen and anti-HBs and/or anti-HBc antibodies. No subject with HBs antigen was found, but 17/163 dentists (10.43%) had virus B markers. Among dentists with positive serology, 3 reported hepatitis developed during their practice. These results are compared with data from the literature concerning dentists, dental health personnel and a population unexposed to the risk associated with dental surgery. Non-specific prevention can reduce the risk of contamination, but only immunization against hepatitis B can provide effective and long-lasting protection.
