Lichen planus is a chronic inflammatory skin condition affecting about 1-2% of the adult population. It usually affects adults older than 45 years, although it may affect younger adults and children. It is more common in women than in men (1.4: 1).
Oral lichen planus affects 50% of patients with skin lichen planus but may occur without skin lesions elsewhere. All areas inside the mouth can be affected. There may be no symptoms but it can cause discomfort, lumps and ulcers.
There are many different forms of Lichen Planus
What causes Lichen Planus
Potentially the conditions may be triggered by medications, contact allergy to dental materials (dental amalgam or toothpaste), trauma and viral infection.
Complications of oral lichen planus
Lichen planus may rarely lead to oral cancer (squamous cell carcinoma). Persistent ulcers should undergo biopsy.
Management of oral lichen planus
A specialists opinion is often required to advise on management strategy and to rule out the possibility of oral cancer.
