Abstract

L, Leonardo M et al. Prevalence and risk factors for the development of recurrent aphthous stomatitis. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2010, vol.10, n.2, pp. 61-66. ISSN 1808-5210.

The aim of this study was to determine the self-reported, clinical prevalence and risk factors for the development of recurrent aphthous stomatitis. This is a cross-sectional study carried out with a calculated sample of 450 individuals selected from the individuals awaiting treatment at the Dental Clinic of the University of Pernambuco. All patients were interviewed and an oral examination was conducted. Information on risk factors was assessed during an interview by means of a specific questionnaire. Statistical analysis included descriptive and inferential analyses, and associations between categorical variables were tested using the X2 statistic. A high (78.67%) prevalence of recurrent aphthous stomatitis was found, mainly among women, although the clinical prevalence was 5.9%. Among the risk factors, diet was the most frequently mentioned (28.2%) by patients, followed by injuries and stress (19.2% and 10.5%, respectively). No significant association was found between recurrent aphthous stomatitis and the common cold. Tobacco use was not associated with the development of recurrent aphthous stomatitis (p>0.05). Statistical significance was observed between alcohol consumption and aphthous stomatitis (p<0.039). It was concluded that the prevalence of recurrent aphthous stomatitis is high and the most common risk factors are diet, trauma and stress.
