A cross-sectional study was carried out involving 451 children 3-5 years of age. A clinical exam was performed to evaluate the malocclusions according to criteria proposed by Foster and Hamilton. This examination was conducted by a calibrated dentist. Parents/caregivers answered the Early Childhood Oral Health Impact Scale (ECOHIS) for the assessment of Oral Health-Related Quality of Life (OHRQoL) and the questionnaire on socioeconomic and demographic characteristics. Data analysis involved descriptive statistics, chi-square, Mann-Whitney and hierarchically adjusted Poisson regression. The prevalence of malocclusion was 28.4%. The most frequent conditions were posterior crossbite (20.4%), anterior open bite (9.5%) and increased overjet (8.4%). A significant association was found between anterior open bite and OHRQoL (p< 0.001). The adjusted analysis confirmed the association between anterior open bite and a negative impact on quality of life (PR = 2.55; 95%CI: 1.87 to 3.47; p< 0.001). Anterior open bite was associated with a negative impact on the quality of life of preschoolers.</p></div> 2018-09-19 02:56:49 Malocclusion Child Preschool Quality of Life
