Methods: A cross-sectional prevalence study was carried out to assess the prevalence and site distribution of Oral Mucosal Lesions in patients attending outpatient department of Shivam Dental Clinic, Lakhimpur. The sample size was estimated to be 150. A single examiner previously trained for the diagnosis of Oral Mucosal lesions made all examinations. The data was collected using the WHO oral health assessment form 2013. The data analysis was done using the SPSS version 20.

Result: The results stated a strong association between age, chewing tobacco smoking and oral lesions.

Conclusion: The present study concludes a positive relation between intake of tobacco in any form with oral mucosal lesions hence an additional effort to educate the masses about the hazardous effects of tobacco should be a priority for both governmental and non-governmental agencies.
