Background: Oral Submucous Fibrosis (OSMF) is a persistent and gradually developing disorder that impacts the mouth and occasionally the throat. It is marked by an inflammatory response just beneath the epithelium and alterations in the fibroelastic components of the lamina propria. These changes result in stiffness of the oral mucosa, limited mouth opening (trismus), and challenges with eating. OSMF is distinguished by its significantly elevated potential to progress into malignancy, compared to other oral lesions with a risk of malignancy, predominantly affecting those of Indian and Southeast Asian descent. The global prevalence rate stands at 2.28% - 8.62%, with a notable gender disparity in occurrence and a malignant transformation rate of 4.2%. Aim: The objective of this research is to evaluate the prevalence and distribution by gender of OSMF stages within a private dental institution, with a particular emphasis on examining the relationship between the frequency of the disease and the occurrence of its stages. Materials and Methods: Over a period of 32 months, a cross-sectional analysis was carried out in the outpatient section of the Department of Oral Medicine and Radiology. After receiving approval from the ethics committee, 337 individuals diagnosed with OSMF were selected for inclusion in the study, with information categorized according to gender and age. Results: The study found a significant male predominance (94%) among the patients, with a mean age of 31-50 years. Stage 2 OSMF was more prevalent among both genders, followed by stage 3 and 1, indicating a specific pattern of disease progression. Discussion: Consistent with previous studies, our research confirmed a male predominance in OSMF occurrence. The age and stage distribution aligns partially with existing literature, suggesting a predominant affliction of individuals in their mid-life. Contrary to Anuna Liala Mathew et al.'s findings, our study observed a higher prevalence of stage 2 OSMF, underscoring potential variations in disease progression or detection practices. Conclusion: OSMF presents a significant public health challenge due to its high malignant transformation potential and association with arecanut and tobacco use. This study highlights the urgent need for public education on the adverse effects of these substances and calls for enhanced awareness and management strategies for OSMF, particularly considering its prevalence and severity among males in the studied population.
