Aim: To assess the awareness of dental students and general public about oral cancer. Background: Oral cancer is one of the most common malignancy seen in head and neck region. The common causes for oral cancer include tobacco consumption (smoke and smokeless), areca nut, betel nut and others. Materials and Methods: 2 groups were formed with 150 participants in each group. The groups included dental students (final year BDS students and Interns) and general public from Chennai. Awareness of etiology, clinical features and management of oral cancer was assessed by means of a questionnaire. Reason: Though oral cancer is the most commonly encountered malignancy in head and neck region, there is poor awareness regarding its etiology, clinical features and management. An early diagnosis can lead to improved survival rate and better prognosis in many cases. Therefore awareness among the dental students and general population is essential for prevention, early diagnosis, improved prognosis and follow up.
