Abstract

The aim of the present study was to investigate the knowledge about oral cancer in a Brazilian population, including initial clinical signs, causal factors, and the health professional of first choice when suspected of the disease. A total of 2261 participants were interviewed in a cross-sectional study, to investigate associations between sociodemographic descriptive variables and knowledge of oral cancer, risk factors, disease precursor lesions, and health professional of choice for diagnosis. The variables were descriptively analyzed and possible associations investigated considering p values < 0.05. A total of 83.4% of participants reported knowing about oral cancer, and 59.5% reported knowing about potentially malignant lesions; both variables were associated (p < 0.0001). Tobacco was identified as the main risk factor (83.6%), followed by family history (66.2%), and poor oral hygiene (54.5%). Interviewees with higher education level had greater knowledge about cancer (p < 0.0001), and the dentist was the health professional of choice for 43.1% of those who knew about the disease (p = 0.007), with the generalist being the most sought specialist. The population evaluated had a low knowledge of oral cancer given the lack of specific clarifications on etiological factors and risk situations. Health education initiatives are necessary to increase population awareness of potentially malignant oral lesions and improve early diagnosis and recognition of the dentist as a qualified professional for diagnosis of the disease.
