Oral Mucosal Lesions in a Cross-Sectional Study of 200 Dermatologic Outpatients.

Oral mucosal lesions (OMLs) present with a variety of manifestations, emanating largely from tobacco chewing, smoking, and consumption of alcohol. Evolution of the lesions may be facilitated by poor oral hygiene and restorative dental materials, as well as by trauma, infections, and immune-mediated diseases. Two hundred consecutive patients seen at a pre-eminent dermatologic clinic formed the study group. They were interviewed about clinical manifestations, duration of the lesion, patient's age and sex, and incriminating factors. After informed consent had been gained, a thorough clinical examination was performed to define the precise morphology, site, and distribution of lesions. Confirmation of the clinical diagnosis by histopathology and other relevant techniques was confirmed.
