INTRODUCTION: Soft tissues and superficial mucosa disorders are common oral health problems, associated with several symptoms, occasionally affecting important normal oral functions. Knowledge on the epidemiology of oral lesions in a population helps the diagnosis, treatment and prevention of these lesions, contributing to the development of strategies to ensure the overall health of individuals. The aim of this study was to access the prevalence of oral mucosal lesions and the impact of this condition on Oral Health-Related Quality of Life (OHRQoL) in children with 5 years of age.

METHODS: In 2009, a sample of 1,303 children born in Pelotas (Cohort 2004) was selected to participate in the study. Data were collected by a questionnaire application to mothers and clinical examinations of children in their household. Early Childhood Oral Health Impact Scale (ECOHIS) was used to access caregivers’ perception on children’s OHRQoL. Software STATA 11.0 was used to perform data analysis.

RESULTS: The prevalence of the oral mucosal lesions was 30.1% (95% CI 27.5-32.9). Multivariate Poisson Regression analysis showed that, after adjustments for confounders, children with oral mucosal lesions presented higher impact on overall OHRQoL (RR 1.38 95% CI 1.11;1.72). Analyzing specific domains, children with lesions also presented higher impact on children symptoms (RR 1.46 95% CI 1.20;1.66) and family functional (RR 3.14 95% CI 1.59;6.22) domains. In conclusion, there is a high prevalence of oral mucosal lesions in 5-yrs-old children and these lesions lead to an impact on OHRQoL.

CONCLUSIONS: The overal results showed a high prevalence of oral mucosal lesions in the surveyed population and these lesions impacted in the children' oral health-related quality of life. These findings highlight the importance of valorizing the oral health conditions in both epidemiological research and clinical practice
