SANTOS JUNIOR, Valdeci Elias dos et al. PREVALENCE OF MALOCCLUSIONS IN DECIDUOUS DENTITION AND ITS RELATIONSHIP WITH SOCIOECONOMIC RISK, AGE, AND GENDER: A CROSS-SECTIONAL STUDY. Odontol. Clín.-Cient. (Online) [online]. 2016, vol.15, n.2, pp. 115-118. ISSN 1677-3888.

Background: one of the most frequent oral problems in the world is malocclusion, interfering in the population welfare. Aim: This study aimed to assess the prevalence of malocclusions in deciduous dentition of the Brazilian children and its relationship with age, gender and family income. Methods: 261 children from 3-6 years old were examined according to the criteria established by the World Health Organization guidelines and the malocclusions were assessed following the criteria of Foster & Hamilton. A validated questionnaire was applied to verify the malocclusions and collect information about age and family income. The Pearson's chi-square test was used to verify the relationships between malocclusion and the variables analyzed. Results: Class I canine relationship represented 82.8% of the sample, followed by Class II with 9.2% and Class III with 8%. It was also detected overjet (9.6%), anterior crossbite (4.6%), posterior crossbite (9.6%), open and deep bite (13.4%). However, there was no statistically significant association between malocclusion and variables: age (p = 0.359), sex (p = 0.308) and family income (p = 0.405). Conclusion: The prevalence of malocclusion was high and was no associated with family income, age or gender. It is important emphasize that early orthodontic intervention can prevent repercussion in the permanent dentition avoiding complex and costly orthodontic treatments.
