Definition:
Oral lichen planus is an inflammatory condition involving the lining of the mouth. It occurs most frequently on the inside of the cheeks, but can affect the gums, tongue, lips and other parts of the mouth. Sometimes, oral lichen planus involves the throat or the esophagus.
Diagnosis:
Usually, a dentist is the first to notice oral lichen planus during a routine examination.
Treatment:
Treatment differs depending on the severity of symptoms and the cause of the condition, if known. Mild symptoms may need only self-care measures and periodic observation by the doctor. More bothersome symptoms may be treated with ointments or creams to lessen inflammation and itching of the mouth.
Symptoms and Signs:
Oral lichen planus may cause one or more of the following signs and symptoms in the mouth and throat: small, pale raised areas or bumps that form a lacy network on the tongue or inside the cheeks; shiny, red, slightly raised patches on the tongue or cheeks; red, open sores in the mouth; pain, tenderness, burning or itching in the mouth; dry mouth; and a metallic taste or a blunted taste sensation
Causes:
The exact cause of oral lichen planus is not known. In certain cases, the condition appears to be triggered by an allergic or immune reaction to one or more substances. Certain medical conditions are sometimes linked with oral lichen planus, but often the source can't be determined.
