Introduction: Several Oral Mucosal lesions carry potential risk of developing into cancer. Therefore, early detection and prompt treatment of oral lesions are key to optimal outcomes. Aims: The main aim of our study was to assess the prevalence and distribution of oral mucosal lesions in population of Jammu, J & K. Materials and Method: Total 905 patients aged 18 and above reporting to the outpatient department of Oral medicine and radiology of Institute of Dental Sciences, Sehora, Jammu were selected for the prospective study. The diagnosis of Oral mucosa lesions was done in line with WHO criteria. Evaluation of type of oral mucosal lesion, its prevalence and site of lesion was evaluated.
