Oral Submucous Fibrosis

📖What is Oral Submucous Fibrosis?

Oral submucous fibrosis is a chronic, progressive condition in which the tissue lining the mouth and throat becomes increasingly fibrous and stiff, gradually restricting the ability to open the mouth and move the tongue. It is strongly associated with the chewing of areca nut, betel quid, and related products, which trigger a persistent inflammatory response that leads to abnormal collagen deposition beneath the oral mucosa. The condition is considered a potentially malignant disorder, meaning it carries a notable risk of progressing to oral cancer over time, making early diagnosis and habit cessation particularly important. It is especially prevalent in South Asian populations where areca nut chewing is culturally common.
