Hepatitis G virus: Relevance to oral health care

Objective. To review the current literature on the hepatitis G virus (HGV) infection, with particular attention to the aspects of interest for the den tal staff. Material and methods. The authors searched for original research and review articles on specific aspects of the HGV infection including virology, epid emiology, transmission, natural history, and dental aspects of HGV infectio n. The relevant articles were evaluated and reviewed. Results. HGV is a parenterally transmitted RNA virus that may cause acute, chronic, and fulminant liver disease; however, the real pathogenic potentia l of this virus and its possible effect on other hepatitic infections is st ill to be clarified. Preliminary studies have failed to demonstrate strong relationships between HGV infection and any oral disease. At present, data on the prevalence of HGV infection among health care workers are scarce. Ne vertheless, in view of the potential transmission rates of HGV and the lack of effective immunization, HGV should be regarded as a potential occupatio nal hazard for medical and dental staff. Conclusion. Many virological, medical, and oral aspects of HGV infection ne ed to be further investigated; nevertheless, until related data are availab le, HGV should be considered to be an infection that may be transmitted dur ing dental care.
