Hepatitis B virus infection. Current status in dentistry.

HBV is a serious threat to members of the dental team. Dental personnel who are carriers of HBV, many of whom may not be aware of their status, are also at risk for hepatitis delta infection. In 1991, the Occupational Safety and Health Administration issued an instruction (in the Federal Register Part II, 29 CFR Part 1910.1030, 56-235)64175-64182) on Occupational Exposure to Bloodborne Pathogens--Final Rule, mandating that HBV vaccine be offered by employers free of charge to all at-risk employees. From a public and professional health perspective, such a mandate was a significant step forward. It is hoped that this update will assist employers to understand better their role in providing HBV vaccine and will assist employees in understanding why acceptance of vaccination is of prime importance to practitioners and staff, their families, and their patients.
