Oral Lichen Planus with Underlying Diseases

Abstract

Oral lichen planus is a chronic inflamatory mucocutaneous disease of unknown etiology. An immunologically induced degeneration of oral epithelial cells has been suggested. It is a common oral dermatosis and one of the most frequent mucosal pathosis encountered by dental practitioners. Furthermore, it may be associated with many underlying diseases. Oral lichen planus has been reported in COVID-19 patients as well. Therefore, dentists should realize about this lesion with underlying diseases.
