Background: Oral submucous fibrosis (OSF) is the oral premalignant lesion with the highest malignant potential. Oral submucous fibrosis (OSMF) is increasingly recognised as an Indian illness worldwide. It has one of the highest rates of malignant transformation among potentially malignant oral lesions and diseases, making it a source of concern for dental specialists. Understanding the precise involvement of alkaloids and other etiological factors in pathogenesis would aid in the management and treatment of the disease. The purpose of this study is to determine the prevalence of OSMF in betel nut chewers of various ages who visit the Dental College and Hospital. Materials and Methods: The study included 798 OSF patients who visited the Department of Oral Medicine and Radiology dental outpatient clinic over the course of 18 months. In the presence of visible light, a thorough case history and clinical examination were conducted. OSMF was diagnosed based on difficulties in opening the mouth and the presence of blanched oral mucosa with palpable fibrous bands. Burning sensations, salivation, tongue protrusion, tobacco intake habits, and related malignant alterations were among the other diagnostic symptoms. The research looked at age groups, habit length, habit frequency, and habit type. A basic correlation analysis was carried out.
