Background: Cancer is a menace to public health and is the most common cause of morbidity and mortality. The incidence of oral cancer among men in Pondicherry is found to be one of the highest rates of cancer in the world. The present survey was conducted to assess the relationship between sociodemographic factors and oral cancer awareness level. Materials and Methods: A questionnaire-based survey was conducted among the patients who reported to the dental college and hospital in Pondicherry for routine dental examination. The questionnaire comprised of 19 questions that assessed the participant's awareness regarding oral cancer, signs and symptoms, and the risk factors. Sociodemographic information was also recorded. Data collected were analyzed using Statistical Package for the Social Sciences version 20. Results: A total of 503 participants participated in the study comprising 61.6% males and 38.4% females. A significant difference was noted in awareness level and knowledge with respect to gender, place of residence, and marital status (P < 0.001). Males had higher mean scores when compared to females and urban population was more knowledgeable compared to rural group. Post hoc analysis showed that the awareness was least among the older age group (>50 years) with a significant statistical difference (P < 0.001). Comparison between different education groups revealed a higher awareness level among the graduate group, and working group was more knowledgeable in all three domains. Conclusion: Sociodemographic factors were found to be significantly associated with oral cancer awareness, knowledge of early symptoms, and risk factors.
