Abstract

Studies on site specific risks for oral cancers are few. Present investigation explores the possible role of human sociodemographic factors in causing oral cancer. Majority of patients had poor oral hygiene (85.5%) and belonged to 51-60 years age group (35.7%). Most of the subjects were agriculture workers (30.3%). Tongue and floor of mouth included majority of the affected sites (77.2%). Male to female ratio was highest for tonsil (32.3%) but differed marginally for other subsites. Majority of females used tobacco (81%) while males users of tobacco, alcohol and smoking reported in nearly equal proportions. Tobacco and smoking were found as primary risk factors for several intraoral subsites. However, for tongue, palate and lip no risk factor could be identified from given patients' characteristics. In general, tobacco posed high risk for buccal mucosa and alveolus in comparison to other subsites. Smoking affected tonsil and floor of mouth more than other sites. Alcohol posed more risk for buccal mucosa and floor of mouth than tongue.
