Hepatitis C virus (HCV) infection is a common worldwide problem, giving rise to long-term viral carriage and risk of chronic hepatic disease, hepatic malignancy and a wide spectrum of immunologically mediated disorders. The present report describes relevant data suggesting that nosocomial transmission to oral health care workers is unlikely, but in view of medical and occupational consequences of such infection, and the absence of long-term effective treatment or vaccine, the oral surgery profession must continue to be vigilant and to maintain the highest standards of infection control procedures to minimize the possible acquisition of HCV during dental treatment.
