Factors associated with the prevalence of anterior open bite among preschool children: A population-based study in Brazil

Abstract

INTRODUCTION: The aim of this study was to identify factors associated with the prevalence of anterior open bite among five-year-old Brazilian children. METHODS: A cross-sectional study was undertaken using data from the National Survey of Oral Health (SB Brazil 2010). The outcome variable was anterior open bite classified as present or absent. The independent variables were classified by individual, sociodemographic and clinical factors. Data were analyzed through bivariate and multivariate analysis using SPSS statistical software (version 18.0) with a 95% level of significance. RESULTS: The prevalence of anterior open bite was 12.1%. Multivariate analysis showed that preschool children living in Southern Brazil had an increased chance of 1.8 more times of having anterior open bite (CI 95%: 1.16 - 3.02). Children identified with alterations in overjet had 14.6 times greater chances of having anterior open bite (CI 95%: 8.98 - 24.03). CONCLUSION: There was a significant association between anterior open bite and the region of Brazil where the children lived, the presence of altered overjet and the prevalence of posterior crossbite.

Association between occlusal characteristics and the occurrence of dental trauma in preschool children: a case‐control study

“…In contrast, anterior crowding and overjet malocclusions were associated with trauma in the presence of confounding variables, but they lost their significance when adjusted for occlusal characteristics. Malocclusion in the primary dentition does not normally appear in isolation . Overjet is often accompanied by crowding, altered arch shape, posterior crossbite or open bite .…”

“…Both dental trauma and malocclusion in the primary dentition are preventable and treatable problems . In a randomized clinical trial, the removal of the pacifier sucking habit was better than the use of a thin‐neck pacifier for the reduction in the occurrence of overbite .…”

“…Malocclusion in the primary dentition does not normally appear in isolation. 20 Overjet is often accompanied by crowding, altered arch shape, posterior crossbite or open bite. 20 In the present investigation, only the anterior open bite remained in the final model of the multivariate analysis because it was more strongly associated with dental trauma than the other occlusal features.…”

“…Both dental trauma and malocclusion in the primary dentition are preventable and treatable problems. 14,15,20 In a randomized clinical trial, the removal of the pacifier sucking habit was better than the use of a thin-neck pacifier for the reduction in the occurrence of overbite. 26 Therefore, favouring the normal development of occlusion may reduce the occurrence of dental trauma in the primary dentition and its consequences in the mixed and permanent dentitions.…”

Occlusal and cephalometric characteristics of anterior open bite in 5-10 year-old Colombian school children

“…14 AOB has been associated with non-nutritive sucking habits. 15 These habits persist due to boredom, stress, anxiety, hyperactivity, disabilities and hunger, 16 among others. Consequently, some kind of relationship between a state of malnutrition and growth in the diagnosis of AOB in children may be expected.…”
