Oral sub mucous fibrosis is a chronic, complex, irreversible, highly potent pre-cancerous condition characterized by juxta epithelial inflammatory reaction and progressive fibrosis of the submucosal tissues such as lamina propira and deeper connective tissues. The condition is linked to oral cancers and is associated with areca nut chewing which is the main component of betel quid. The causes of these diseases are excessive consumption of red chilies, prolonged deficiency to iron & vitamins in diet, extreme climatic conditions, immunological diseases& consumption of dried products such as pan masala and gutkha which have higher concentrations of areca nut. Here classification is done based on clinical, functional and physiological diagnosis.
