Abstract
Introduction
All malocclusion has a multifactorial origin, and among the factors that trigger it are the habits. The appearance of a habit can be related to the emotional, physiological or conditioned learning of the individual.
Objective
Evaluate the relationship between habits and malocclusions associated with respiratory problems in 5-year-old students.
Material and method
A cross-sectional study were carried out with a sample of 753 children belonging to the municipal education network of the city of Araraquara-SP. Clinical exams were performed for malocclusion evaluation (Foster & Hamilton), applying questionnaires to the parents for evaluation of socioeconomic and demographic condition, oral health related quality of life (ECOHIS) and habits. Data analysis was performed by bivariate analysis using chi-square test followed by multiple logistic regression model considering 5% significance level.
Result
The prevalence of children with respiratory problems and/or allergies was 46.9%, with malocclusion was 58.7% and with some type of deleterious oral habit was 12.0%. Male children were 1.40 times more likely to present respiratory problems or allergies and children with some deleterious oral habits were 1.95 times more likely to present respiratory problems or allergies.
Conclusion
It was observed that male children, children that presented deleterious oral habits, and children with bruxism are more likely to have respiratory problems and/or allergies.
