Introduction: Mouth cancer is considered a public health problem due to high rates of mortality and morbidity. Knowing about disease risk factors and clinical signs are the basis for prevention and early diagnosis. Public campaigns, such as screening and population awareness, were carried out, although studies challenged the reason for not reaching the main risk group. Methodology: This is a retrospective observational study, in which a survey of the epidemiologic data of public campaigns conducted by the Federal University of Bahia (FUBA) between 2005 and 2018 in Salvador and the metropolitan region was carried out. RESULTS: A total of 1390 people were evaluated, predominantly female (71.44%), with a mean age of 44 years. We found 241 fundamental lesions. In the records that reported diagnostic hypothesis, we found 9 cases related to oral cancer, 5 cases of leukoplakia, and 4 cases of actinic cheilitis. Of those who reported smoking and drinking, 16.9% reported tobacco use, and 26.3% reported alcohol use. Of the total sample, 270 diagnostic hypotheses, there was a greater predominance of normality variation. Of the patients with soft tissue lesions, 166 were referred for evaluation by the stomatologist. Conclusion: Campaigns are considered good strategies to promote educational actions and raise community awareness; therefore, they should be encouraged.
