Abstract

Among the oral problems that most affect the population, the most prevalent are caries, periodontal disease and malocclusion. The malocclusion is an anomaly of tooth development and / or dental arches, causing aesthetic and functional problems, considered a public health problem. This study aims to evaluate the association between malocclusion and health–related quality of life (HRQoL) and oral health– related quality of life (OHRQoL) in 361 adolescents from 12 years of public schools in the city of Manaus. To determine the severity of malocclusion used the Dental Aesthetic Index (DAI); for OHRQoL used the questionnaire Child Perceptions Questionnaires (CPQ 11-14) and HRQoL was assessed using the KIDSCREEN-52 instrument. Data analysis was performed to compare means using the Mann- Whitnney and Kruskal-Wallis, with a significance level of 5%; the bivariate analysis between the independent variables and the quality of life measures and multivariate logistic Statistical analysis was performed using the chi-square test, with a 5% significance level. In association of the variables with the first and last quartiles of the CPQ 11-14 was found that students living in houses with 7 people or more (p = 0.013) and been to the dentist in the private service, plan or arrangement (p = 0.020) has less impact on OHRQoL and between DAI categories was not found impact. In association of the variables with the first and last quartiles of the KIDSCREEN-52, students who sought the dentist in case of pain, extraction or treatment, had no impact on HRQoL (p = 0.049). Among the categories of DAI, definite malocclusion (p = 0.033), severe (p = 0.009), and handicapping (0.027) was found associated with HRQOL. Thus, it can be concluded that adolescents with a favorable socioeconomic status and who have access to dental services have a good quality of life and adolescents with malocclusion has a negative impact on health-related quality of life (HRQoL).
