“…On the other hand, the relation between malocclusion prevalence in the primary dentition and socioeconomic factors has dissimilar results in the literature. 27 Some studies found no association between these variables, 28 others found a higher prevalence of malocclusion in the most disadvantaged socioeconomic levels, 29 and others an inverse association. 19 The differences between these studies' results can be explained by several factors, such as methodological differences or cultural characteristics of the populations studied.…”

Objectives: To study the prevalence of malocclusion in deciduous dentition and its associated factors. Methods: The target population consisted of children between 3 and 5 years old who attended four kindergartens in Alvalade, Lisbon. Data was collected through a questionnaire to parents and an intraoral examination of children. The questionnaire collected sociodemographic and non-nutritive sucking habits information. The intraoral examination collected data about the child’s occlusion and dental caries. Results: The sample included 89 children. The prevalence of malocclusion was 83.9%, and the most prevalent types were crowding (44.8%) and distocclusion (41.4%). Most of the children (68.2%) had non-nutritive sucking habits, of which using a pacifier was the most frequent (81.6%). The habit of using a pacifier after three years of age was reported by 67.8% of the participants. The variables statistically associated with malocclusion (p<0.05) were age, mother’s education level, non-nutritive sucking habits, use of pacifiers and thumb sucking, and caries in primary teeth. Conclusions: The prevalence of malocclusion and non-nutritive sucking habits was high. Early diagnosis and intervention are important to avoid serious malocclusion problems and structural and functional changes.
