    Abstract:
    OBJECTIVE: The aim of the present study was to identify factors associated with the occurrence of distoclusion among preschool children in southern Brazil. STUDY DESIGN: A cross-sectional study was carried out with a sample of 1026 children aged two to five years enrolled at public preschools in the city of Canoas, Southern Brazil. Interviews were held with parents/caregivers to acquire demographic, socioeconomic and behavioral data. Six examiners who had undergone a training and calibration exercise performed the oral examinations. Distoclusion was recorded when the cusp of the maxillary canine was in an anterior relation to the distal surface of the mandibular canine during centric occlusion. Statistical analysis involved simple and multivariate Poisson regression with robust variance. RESULTS: The prevalence of distoclusion was 36.5% (375/1026). This condition was more frequent in younger children, those classified as white or brown, those who were breastfed for a shorter period of time, those who used a pacifier and those who were bottle fed. The multivariate analysis demonstrated that the likelihood of exhibiting distoclusion was greater among two-year-olds (P=0.038), three-year-olds (P=0.023), those classified as white (P=0.016), those who used a pacifier (P<0.001) and those who used to use a pacifier (P<0.001). CONCLUSION: Counseling with regard to the duration of pacifier use could contribute toward reducing the prevalence of distoclusion and its consequences in preschool children.
