Background: Oral cancer is a significant public health concern in India, with high morbidity due to tobacco use, alcohol consumption, and delayed diagnosis. Early detection by dental professionals is essential to improve outcomes. Aim and Objective: To assess the knowledge, attitude, awareness, and clinical practices regarding oral cancer among undergraduate dental students in Melmaruvathur, Tamil Nadu. Materials and Methods: A cross-sectional questionnaire-based study was conducted among 194 undergraduate dental students. The survey evaluated knowledge of risk factors, common sites, diagnostic methods, attitudes toward early detection, and clinical practices. Data were analyzed using descriptive statistics and Chi-square tests. Results: Most students showed good knowledge. The floor of the mouth (68.6%) and squamous cell carcinoma (96.4%) were correctly identified. Tobacco and alcohol (96.9%) and biopsy (71.6%) were recognized appropriately. However, gaps existed in awareness of rarerisk factors and biopsy practice. Conclusion: Students demonstrated good knowledge and attitudes, but further training is needed to enhance clinical practice and awareness.
