Introduction:

oral leukoplakia is a premalignant lesion that usually manifests as a white spot, but it is not usually painful and can go unnoticed.

Objective: to characterize oral leukoplakia in patients of the "Justo Ortelio Pestana Lorenzo" Provincial Teaching Stomatology Clinic during 2019.

Methods:

a cross-sectional descriptive observational study was conducted from January to December 2019 at the "Dr. Justo Ortelio Pestana Lorenzo" Provincial Stomatological Clinic. Twenty-one patients with oral leukoplakia who met inclusion criteria were selected. The variables studied were age, sex, skin color, risk factors and location of the lesion.

Results:

57,1 % of the patients with leukoplakia were between 45 and 59 years of age, 61,9 % were male and 47,6 % were of white skin color. 42,8 % of the area most affected was the mucosa of the cheek. Of the patients examined, 57,1 % were smokers and 28,8 % presented maladjusted prosthesis and deficient oral hygiene.

Conclusions:

patients between 45 and 59 years of age were predominant, with male sex and white skin color, the greatest localization in the mucosa of the cheek and the risk factors were smoking, poor oral hygiene and maladjusted prostheses.
