Specializes in Dentistry

Unknown: The cause of lichen planus is unknown. In certain locales, patients with extensive lichen planus seem to be more likely to have a hepatitis C virus infection of the liver. Often see people with full dentures that seem to get it, but really hard to determine a specific source
