J W Mosley, V M Edwards, G Casey

    The New England Journal of Medicine
    |October 9, 1975
    PubMed
    Summary

    Hepatitis B virus infection was more common in general dentists in 1972. Professional experience correlated with infection rates, suggesting dentists faced a significant occupational hazard from hepatitis B.

    Area of Science:

    • Dentistry
    • Infectious Diseases
    • Hepatology

    Background:

    • Viral hepatitis poses a potential occupational hazard in general dentistry.
    • Understanding the prevalence of hepatitis B virus (HBV) infection among dental practitioners is crucial for patient and provider safety.

    Purpose of the Study:

    • To evaluate the prevalence of hepatitis B infection among general dentists.
    • To assess the association between professional experience and HBV infection in dentists.

    Main Methods:

    • A survey of 1245 dental practitioners was conducted at the 1972 American Dental Association health-screening program.
    • Hepatitis B surface antigen and antibody positivity were determined serologically.

    Main Results:

    • 0.9% of dentists were positive for hepatitis B surface antigen, and 12.7% were antibody positive.
    • 43% of dentists with a history of clinical hepatitis during their dental studies or practice were seropositive.
    • HBV infection evidence increased with years of professional experience, independent of geographic region or community size.

    Conclusions:

    • General dentists exhibited an increased frequency of hepatitis B virus infection.
    • The findings suggest a significant occupational risk for dentists and are consistent with endemic HBV circulation in the general population.
