fa Malocclusion and oral health-related quality of life in Brazilian school children ارتودنسی Orthodontics پژوهشي Research <p> <strong>Objective:</strong></p><p>  To test the hypothesis that malocclusion and its impact on quality of life has no effect on 8- to 10-year-old Brazilian schoolchildren as measured by an oral health-related quality of life (OHRQoL) instrument. </p><p> <strong>Materials and Methods:</strong></p><p>  A cross-sectional study was carried out with a population-based sample of 1204 8- to 10-year-old children attending elementary schools in Belo Horizonte, Brazil. Dental examinations were carried out by two calibrated examiners. OHRQoL was assessed using the Brazilian version of the Child Perceptions Questionnaire. The Dental Aesthetic Index was used for the clinical assessment of malocclusion. Dental caries and socioeconomic factors were used as controlling variables. Bivariate analysis involved the chi-square test and the Fisher exact test. A Poisson regression model was employed for the multivariate analysis (P < .05). </p><p> <strong>Results:</strong></p><p>  Anterior segment spacing and anterior mandibular overjet were significantly associated with impact on OHRQoL (P < .05). Schoolchildren with malocclusion were 1.30-fold (95% CI: 1.15–1.46 P < 0.001) more likely to experience a negative impact on OHRQoL than those without malocclusion. Children belonging to families with an income less than or equal to two times the minimum wage were 1.59-fold (95% CI: 1.35–1.88 P < 0.001) more likely to experience a negative impact on OHRQoL than those belonging to families with the highest income. <strong></strong></p><p> <strong>Conclusions:</strong> </p><p> Schoolchildren with malocclusion from lower-income families experience a greater negative impact on OHRQoL. </p><hr><p></p><p> <strong>Source: </strong>The Angel Orthodontists</p><p> <a href="http://www.angle.org/doi/abs/10.2319/010912-20.1" target="_blank"><font color="#0000ff">Full Text</font></a></p> Oral health-related quality of life, Malocclusion, Children 0 0 http://idai.ir/browse.php?a_code=A-10-32-1918&slc_lang=fa&sid=1 Fernanda Sardenberg 10031947532846008981 10031947532846008981 No Department of Pediatric Dentistry and Orthodontics, Faculty of Dentistry, Federal University of Minas Gerais, Belo Horizonte, MG, Brazil Milene T.Martins 10031947532846008982 10031947532846008982 No Department of Pediatric Dentistry and Orthodontics, Faculty of Dentistry, Federal University of Minas Gerais, Belo Horizonte, MG, Brazil Christiano B.
