Estudo sobre lesões bucais em pacientes atendidos em ambulatório da Universidade Federal de Santa Maria - RS

Abstract

The aims of this cross-sectional study were to determine the prevalence of oral mucosal lesions in patients assisted at the Semiology Ambulatory of Odontology Course at the Federal University of Santa Maria from 2001 to 2005, and to explore the relationship of oral disease and others variables, principally, the tobacco. A total of 864 subjects were included in the study. The information’s patients were collected from register of ambulatory and the analysis statistic was carried out through descriptive, chi-square tests and the odds ratio (OR) was computed. The mean age was 45, and 68.40% were women. Oral mucosal lesions were observed in 567 (65.63%) of participants, and these patients 446 (78.66%) had one specific lesion, 104 (18.34%) had two lesions, and 28 (4.94%) had three or more simultaneous lesions. The most common lesion was found to be candidoses with a prevalence of 23.26%, followed by hyperplasia (7.87%). Significant relationships were found between presence of oral pathology and age (OR = 1.03; IC 95% 1.02 to 1.04); civil status: married (OR = 2.19; IC 95% 1.60 to 3.01), widower (OR = 3.17; IC 95% 1.78 to 5.62), and tobacco (OR = 1.84; IC 95% 1.29 to 2.63). In conclusion, there was a high prevalence of oral mucosal lesions in this study. It’s very important to promote prevention programs, which aim to reduce tobacco use as well as alcohol consumption, because they contribute to the transformation of normal cells to cells exhibiting malignant.
