Hepatitis C virus and oral disease: a critical review.
Hepatitis C virus (HCV) infection is widespread with an estimated 3% of the world population being infected. Acute infection is usually mild but chronicity develops in as many as 70% of patients, of whom at least 20% will eventually develop cirrhosis. A further 1-4% of cirrhotic individuals will develop hepatocellular carcinoma. Infection with HCV may have effects on various organs other than the liver. HCV has been causally associated with a remarkable array of extrahepatic manifestations, some of which remain unproven. This review discusses the evidence implicating HCV in the aetiology of two important oral conditions, namely Sjögren's syndrome and lichen planus.
