ABSTRACT
Early detection and management of potentially malignant oral lesions can significantly reduce progression of these lesions into invasive cancer, and would thus reduce morbidity and fatality rate. Cancerous and potentially malignant lesions show dysplastic feature which is mostly detected by biopsy. However, biopsy has a certain constraints like (i) biopsy can cause delay in the result, (ii) experienced pathologist must expound the biopsy sample (iii) sometimes can cause spread of cancer cells, (iv) cannot be done repeatedly. Therefore, in potentially malignant lesions and cancer optical coherence tomography (OCT) is utilized to detect early dysplastic changes. Therefore, we are presenting a review on the applications of OCT in oral mucosal lesions.
