Introduction: Oral cavity is the most predominant location in the head and neck region for primary malignant tumors1. In India, the extremely popular use of the smokeless tobacco product called gutkha, along with betel quid especially among the youth has lead to a greater risk of developing oral cancer. Thus, the objective of the present study is to determine the level of awareness of oral cancer, knowledge about its early signs and the associated risk factors among the general population. Objectives: To study the awareness of oral cancer amongst Patients visiting dental outpatient Department (OPD) Material and Methods: The questionnaire consisted of 11 questions regarding knowledge, causes and signs of cancer. One thousand patients attending Oral medicine OPD in the age range of 16–80 years were included in study whereas those with the medical background were excluded. Results– The result of awareness questionnaire showed that 831 (83.1%) respondents were aware of the term “oral cancer” and 685 (68.5%) knew the causes.310 (31%) knew the meaning of the crab sign. About 534(53.4%) of patients had knowledge about the early signs and symptoms of oral cancer. 456 (45.6%) patients had known the treatment modalities used in oral cancer . Conclusion – This awareness study conducted among dental patients revealed that most of the patients are aware about oral cancer and its causes. This is because of awareness programs shown on television, Cinema and newspaper. Less public knowledge regarding early signs and symptoms and treatment of oral cancer suggest that there is a need to emphasize on this point in public education programmes in future.
