Abstract
Objective: Te objective of the study was to assess the prevalence of oral mucosal lesions and identify the risk factors for its occurrence, in an urban adult population from Uruguay. Methods: Tis cross-sectional study selected 922 subjects (537 F/385M, age 15-24, 35 -44 y 65-74 years old) using a multistage probability sampling strategy. Prevalence and confdence intervals (95%) were calculated accounting for the survey design. Results: Candidosis and proliferative lesions were observed in 26% and 17% of the subjects. Tis lesions were signifcantly associated with female gender. Te prevalence of leukoplakia was 7% and in the multivariable analysis this lesion was signifcantly associated with yerba mate consumption. Conclusions: Oral mucosal lesions are present in elderly people in Uruguay, suggesting the need for improved standards of prevention, diagnostic and opportune treatment for these lesions
