Objective: To determine the level of knowledge concerning oral cancer among a sample of elderly people with various sociodemographic characters, behavior, and dental visits in Depok City, Indonesia. Material and Methods: A cross-sectional study of oral cancer awareness was conducted among 100 elderly people in Depok City using an intervieweradministered questionnaire. We collected information regarding sociodemographic data regarding age, gender, marital status, education, health insurance, risk factors and early signs of oral cancer, and questions related to lifestyle factors relevant to oral cancer, including smoking, drinking alcohol, tobacco chewing, betel quid chewing, and dental visits. Data were analyzed through the Statistical Package for Social Sciences and presented through descriptive and inferential statistics. Statistical significance level was set at p<0.05. Results: 64% of respondents have poor knowledge of the oral cancer risk factors, while only 25% of respondents have sound knowledge of the early signs of oral cancer. There was a significant difference in the level of oral cancer knowledge according to gender (p=0.01), level of education (p=0.008), smoking behavior (p=0.03), and dental visits (p=0.01). Conclusion: The oral cancer knowledge among elderly people in Depok City is still lacking. Further, some sociodemographic factors influence the level of oral cancer knowledge.
