Oral lichen planus: parameters affecting accurate diagnosis and effective management.

Oral lichen planus is one of the most common mucosal diseases that require management by the dental practitioner. The gingival presentation of this disease can be particularly problematic. Accurate diagnosis is of paramount importance for effective management, and tissue specimens are often required to distinguish this disease from other vesiculo-ulcerative diseases. The lichen planus patient can generally be managed with topical steroids. The use of antibiotics may be an important adjunctive consideration for patients with a concurrent significant periodontal condition. The possibility of carcinoma arising in lichen planus lesions is addressed. The learning objective of this article is to define specific parameters that contribute to the definitive diagnosis in order to promote objective, rather than empirical, treatment and to delineate specific points to address in patient education.
