Summary.  More than two billion people have been infected with hepatitis B virus (HBV). Globally, 350–400 million suffer from chronic HBV infection. It is postulated that dentists and dental staff are infected and transmit the virus to their patients more than any other occupation. The aim of this article is to review the HBV incidence in dental society, the points of view of dentists and their patients regarding transmission of the virus during dental procedures, the occurrence of HBV outbreaks in dental clinics and the importance of methods of preventing HBV infection in dentistry.
