Background: Oral cancer is a becoming leading global cause of morbidity and mortality. It is one of the ten most common cancers in the world. Oral cancer is almost all the time preceded by some type of precancerous lesion. Early detection and elimination of the causative risk factor like tobacco can help in the reduction of the incidence of oral cancer. Aims and Objectives: To study the prevalence of oral precancerous lesions and its correlation with the use of tobacco in tobacco habituated population. Material and Methods: This one year duration study was undertaken on 106 employees of a charitable trust. After taking detailed history about tobacco habituation they were screened for the presence of oral precancerous lesions. Only clinical criteria were used for diagnosis of oral precancerous lesions. Efforts were also made to motivate them to quit the tobacco habit. Results and Observations: Out of total 106 subjects studied, 57 (53.77%) were tobacco users. Prevalence of oral precancerous lesions was (47.16%) in our study population, and all the lesions were exclusively seen in tobacco habitual. In tobacco habitual, oral leukoplakia as a single lesion was found in 18 cases, Erythroplakia in 9 cases and oral sub mucous fibrosis in 16 cases. A total of 9 (14%) subjects were showing multiple oral precancerous lesions. Conclusion: Tobacco acts as a major risk factor in the development of single or multiple oral precancerous lesions and they could be identified by simple oral cavity examination before they undergo malignant transformation.
