Impact of malocclusion on oral health-related quality of life among Brazilian preschool children: a population-based study.
The purpose of the present study was to evaluate the impact of malocclusion on Oral Health-Related Quality of Life (OHRQoL) of children and their families. A population-based cross-sectional study was carried out in Belo Horizonte, MG, Brazil. A representative sample of 1069 male and female preschoolers aged 60 to 71 months was randomly selected from public and private preschools and daycare centers. Data were collected using the B-ECOHIS. In addition, a questionnaire addressing socioeconomic and demographic data was self-administered by the parents/guardians. The criteria used to diagnose malocclusion were based on Foster and Hamilton (1969), Graboswki et al. (2007) and Oliveira et al. (2008). Descriptive, univariate and multiple Poison logistic regression analyses were carried out. The prevalence of malocclusion was observed in 46.2% of the children and deep overbite was the most prevalent type of malocclusion (19.7%), followed by posterior crossbite (13.1%), accentuated overjet (10.5%), anterior open bite (7.9%) and anterior crossbite (6.7%). The impact of malocclusion on OHRQoL was 32.7% among the children and 27.1% among the families. In Poisson multiple regression model adjusted for socioeconomic status, no significant association was found between malocclusion and OHRQoL of the children (PR=1.09, 95% CI: 0.96-1.24) and their families (PR=1.11, 95% CI: 0.94-1.31). It is concluded that children with malocclusion in this sample did not have a negative impact on their OHRQoL and of their families.
