The estimated prevalence rate of leukoplakia is 2% worldwideThose lesions present particularly in the floor of the mouth, tongue, lip and vermilion have a high risk of malignant potential. Five Clinical Criteria Demonstrate a Particularly High Risk of Malignant Change 1)The high risk is considered to be the verrucous type 2)If the lesion is associated with erosion or ulceration then, the lesion is suggested to have high malignant potential 3)The presence of a nodule in the lesion indicates higher malignant potential 4)A lesion that is hard and indurative in its periphery is predictive of malignant change 5)Oral leukoplakia seen in the anterior floor of the mouth and undersurface of the tongue is strongly linked to malignant potential. Treatment : It consists of cessation of smoking or other tobacco related products Also treatment with laser , cryoablation can be done to eradicate leukoplakia
