Hepatitis B and dental personnel: transmission to patients and prevention issues.
Hepatitis B virus (HBV) infection is considered an occupational risk for dental professionals. The Centers for Disease Control have participated in eight investigations regarding dental professionals who were suspected of transmitting HBV infection to their patients. This article summarizes the findings of the investigations, the postulated mechanism of transmission of HBV, control measures suggested, and follow-up of the dental practice for those dentists who were chronic carriers of hepatitis B surface antigen. The approach by the centers for managing dental professionals who are HBsAg positive and those dental professionals who are HBsAg positive and implicated as transmitting HBV infection to patients are outlined. If HBV transmission cannot be interrupted, by suggested measures, then more restrictive measures should be decided on by state or local health officials, or both. These could include removal of the practitioner's license. HBV-infected dental personnel can transmit HBV infection to their patients. The measures suggested for the HBV carrier are designed to allow the dental practitioner to continue practice, but, at the same time, give maximum protection to the patient.
