Abstract
BACKGROUND: Oral cavity cancer is a growing concern, especially in developing countries like India, due to risk factors such as tobacco use, alcohol consumption, nutritional deficiencies, and spicy food intake. Early detection through screening and Mouth Self-examination (MSE) can significantly improve outcomes, but limited awareness and pain in advanced stages lead to delayed detection. This study aimed to assess the knowledge and practice of MSE among tobacco users in urban and rural populations. MATERIALS AND METHODS: A comparative cross-sectional study was conducted involving tobacco users (smoking, smokeless, or both). An observational questionnaire-based approach was employed, with informed consent obtained from participants. A questionnaire in Hindi and English was used, consisting of demographic details and 13 close-ended questions. RESULTS: The analysis revealed that individuals from urban areas (71.9%) exhibited significantly higher awareness of Mouth self- examination (MSE) compared to those from rural areas (1.9%). Chi-square analysis demonstrated that urban residents exhibited significantly higher awareness, understanding, confidence, desire for information, and positive attitudes towards Mouth Self-Examination (MSE) compared to rural residents. Multivariate analysis showed that education had a consistent and substantial impact on both knowledge and practice scores. CONCLUSION: The study highlights substantial urban-rural disparities in mouth self- examination (MSE) awareness and attitudes, with urban residents demonstrating significantly higher levels. Targeted interventions and awareness campaigns are vital to bridge this gap and improve oral health practices, especially in rural areas.
