Oral lichen planus: an update

Oral lichen planus (OLP) has an estimated global prevalence of 1% and is considered to be a disorder that requires lifelong surveillance. Clinical subtypes of OLP include reticular, atrophic, papular, plaque-like, ulcerative and bullous variants. OLP can present with desquamative gingivitis, and women may have associated vulval and/or vaginal involvement. Diagnosis of OLP is based on clinical and histopathological findings. Reticular and plaque-like OLP tends to be asymptomatic and seldom requires treatment. Ulcerative and atrophic OLP can generally be managed with topical corticosteroids. Severe and widespread ulcerative lesions may require systemic drugs. CPD/Clinical Relevance: General dental practitioners need to be able to recognize the different clinical presentations of oral lichen planus and refer appropriately.
