Knowing the occlusal characteristics of deciduous and mixed dentition, its development, changes and possible influencing factors is important for prevention and interception of malocclusion, being it of great epidemiological value. For this,longitudinal studies are appropriate because they observe the same population in different time points. This study consisted of two parts: cross-sectional and longitudinal study. The cross-sectional study investigated the influence of demographic, behavioral and socioeconomic factors at time breastfeeding of the child and the influence of the same in occlusal characteristics of primary dentition. It was found that the statistically significant factors for breastfeeding were time use of baby bottle (p<0.001) and time-use of pacifier (p<0.001), moreover, in relation to dental occlusion were associated the relation of canines (p=0.002), the midline deviation (p=0.013), anterior open bite (p<0.000), overjet (p<0.001), posterior crossbite (p=0.006) and presence of malocclusion (p<0.001). The longitudinal study compared occlusal characteristics present in children in primary dentition and mixed dentition, six years after. Were eligible all children examined in 2007 that, after contact with the mother, were reassessed and were in the mixed dentition. For data collection was performed clinical evaluation, by only one specialized and calibrated examiner, comprising occlusion, presence of visible plaque, dental trauma and experience of dental caries. After, interview was applied to mother investigating age and schooling, current income, child's oral habits, among others, and questioning the child about dietary habits, hygiene habits and selfperception. Descriptive analyzes were performed and to test the influence of the variables on the outcomes were used chi-10 square test, Fisher exact test and McNemar test. It was found that the anterior open bite (p<0.001), spacing (p=0.001), overjet (p=0.012), crowding (p<0.001) and malocclusion (p<0.001) presented association between deciduous and mixed dentition. And veryfing the factors that influence the crowding in the mixed dentition it was found the deciduous arch type (p<0.001), primate spaces (p=0.050) and the presence of crowding in primary dentition (p=0.014). The follow up of occlusion development showed that the presence of malocclusion is associated between deciduous and mixed dentition and thus, prevent or intercept these types of malocclusions in the primary dentition can improve the occlusion in mixed dentition.
