The following variables were analyzed: age, sex, skin color, risk factors, clinical forms presentation of leukoplakia, localization, number of lesions, time of nicotine addiction and malignant transformation.


The 45-64 age group, male sex and persons of mixed race prevailed. The most affected anatomical localization was the residual alveolar edge. Most of those affected presented a single lesion with homogeneous clinical form, and any malignant transformation after their intervention. Nicotine addiction was the most prevalent risk factor.
