Prevalência de más oclusões em crianças de 9 a 12 anos de idade da cidade de Nova Friburgo (Rio de Janeiro)

Abstract

Introduction: Knowledge of a population's epidemiological situation is important in the planning and provision of dental services. Objectives: Assess the prevalence of malocclusion in children aged 9 to 12 years old from public schools in the city of Nova Friburgo, Rio de Janeiro State, Brazil. Methods: A randomly selected sample consisting of 407 children (53.1% female) who were evaluated by a trained professional, after parental consent. Results: The most prevalent malocclusions were crowding (45.5%), excessive overjet (29.7%), posterior crossbite (19.2%), anterior diastema (16.2%), partially erupted teeth (12.0%) and excessive overbite (10.8%). Class I molar relationship prevailed (76.7%). The presence of diastemas was higher in females and excessive overbite was more prevalent in males, both in mixed dentition. Negative overjet and the presence of partially erupted teeth had a higher prevalence in permanent dentition. Conclusion: It was observed that the mere evaluation of malocclusion prevalence does not reveal case severity or treatment need, both of which are important factors in public health planning.

“…The rate of malocclusions was similar to that of other studies evaluating children in general 13,14 . The prevalence of increased overbite in the general population of children is lower 13,14 than that in the present study; this as, therefore, the only characteristic that distinguished the group of mouth breathers.…”

“…followed by Class II malocclusion (36%) and Class III (11,7%).Still in agreement with the data obtained in this investigation, there is a study byBrito, Dias, Gleiser 20 where, knowing that the knowledge of the population's epidemiological situation is important to plan the execution of dental services in a determined population, have conducted a study with the purpose of assessing the prevalence of malocclusions in city-run school children in between 9 and 12 years of age in the city of Nova Friburgo, Rio de Janeiro. The sample was composed of 407 individuals, 191 males and 216 females who were clinically assessed by a trained professional.…”

Occlusal Characteristics of Children with Class I Malocclusion in Northeastern Brazil

“…Borges 37 mentions that excessive spacing between teeth is not commonly found in mixed dentition, except when there is a protrusion of incisors, which confirms the analysis of the present research. Deep bite was less frequent in the study sample; it was found in only 1.6% of the children examined and is in line with the findings of another study 38 . The low percentage of 0.8% of edge-to-edge bite was expected as these occlusal characteristics are more commonly found in patients with class II and III malocclusion, respectively.…”
