Abstract

Smoking chewing of tobacco and areca nut consumption of alcohol has become common social habits in entire world leading to many oral disorders approaching towards cancer. Oral submucous fibrosis OSMF is one of the commonest precancerous conditions of oral mucosa caused mainly by the habit of areca nut chewing leading to generalized fibrosis of oral mucosa that further results in marked rigidity and inability to open the mouth. Worldwide 2.5 million people are affected with OSMF with most cases concentrated on the Indian subcontinent especially southern India. The disease is characterized by atrophied epithelium and juxta epithelial hyalinization followed by fibrosis in the underlying lamina propria of oral mucosa. OSMF has become of great concern to a general practitioner as well as a dentist because of its premalignant nature and resemblance to some dermatological disorders like scleroderma. It is very essential to diagnose this disease at an early stage to prevent further adverse effects on oral health.
