title: [Dental spacing problems and associated factors among Brazilian adolescents].
abstract: The scope of this study was to estimate the prevalence of dental spacing problems and associated factors among adolescents using data from the SB Brazil 2010 survey. The outcomes evaluated were dental spacing problems: space deficit (crowding and misalignment) and excess space (diastema and spacing) obtained using the DAI index. The association of independent variables with outcomes was assessed using a hierarchical model with four levels: contextual, socioeconomic and demographic characteristics, access to services and dental morbidity. Statistical analysis was performed using the chi-square test and univariate and multivariate Poisson distribution to estimate prevalence ratios (PR). The overall prevalence of space problems was 71.43%, with misalignment being the most common type (56.4%). The following aspects were significantly associated with excess space: age of 16, 18 and 19 years; being non-Caucasian (PR = 1.75), perception of speech problems (PR = 1.72) and periodontal pockets 4-5mm (RP = 1.56). For space deficit: family income up to 3 minimum wages, dental visit 1 year or more previously (PR = 1.19) and having one or more decayed teeth on average (PR = 1.32). There was a prevalence of spacing problems, especially with socioeconomic and demographic variables and morbidity as potential risk factors.
