Prevalência da maloclusão e necessidade de tratamento ortodôntico em escolares de 10 a 14 anos de idade em Belo Horizonte, Minas Gerais, Brasil: enfoque psicossocial

Abstract

The objectives of this cross-sectional study were to assess the prevalence of malocclusion and to verify the association between normative orthodontic treatment need and certain psychosocial aspects. The sample (n = 333) was representative of the population of adolescents (10-14 years) in Belo Horizonte, Minas Gerais, Brazil. The dependent variable "normative orthodontic treatment need" was evaluated through the Dental Aesthetic Index (DAI) and the independent variables (gender, age, mother's schooling, economic status, parent's perception of the child's oral aesthetics, parent's perception of the child's orthodontic treatment need, and the adolescent's desire for orthodontic treatment) were evaluated through questionnaires. Descriptive, bivariate, and logistic regression (stepwise forward procedure, p<or= 0.05) analyses were performed. Malocclusion prevalence was 62.0% and normative orthodontic treatment need was 52.2%. The variables adolescent's orthodontic treatment desire and parents' perception of the child's oral aesthetics were significantly associated with normative orthodontic treatment need. These results suggest that psychosocial factors should be considered in making the decision to undergo orthodontic treatment.

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

“…Of the 500 children selected for the study, 73 did not return the signed parental consent document, 13 were not present at school on the assessment day and 7 had already started treatment. The age distribution of the remaining 407 children, according to gender and dentition period, can be seen in Tables 1 and 2, respectively.…”

“…Knowledge of a population's epidemiological situation is vital for planning and providing prevention and treatment services 20 . Several prevalence studies have been conducted on children in mixed or permanent dentition stages 3,4,[7][8][9][10]12,13,19,[25][26][27][28] , but few studies in the Brazilian population approach with any degree of clarity the changes occurring between these periods.…”

Qualidade de vida e saúde bucal em crianças e adolescentes: aspectos conceituais e metodológicos

“…Outros problemas bucais, como os transtornos associados à erupção dentária (AGOSTINI et al, 2001), os traumatismos dentários (TRAEBERT et al, 2004), as patologias dos tecidos moles da boca (AGOSTINI et al, 2001), as oclusopatias (MARQUES et al, 2005), as fissuras labiopalatais (CERQUEIRA 285 et al, 2005) e a fluorose dentária (OLIVEIRA; MILBOURNE, 2001) afetam crianças com frequência variável. Entretanto, existe pouca informação a respeito das suas possíveis consequências funcionais, emocionais e sociais (CORTES et al, 2002;MARQUES et al, 2006).…”

Epidemiology of malocclusion in children and adolescents: a critic review

“…With regard to orthodontic treatment needs, the MSI presented a statistically different proportion The epidemiologic instruments adopted by researchers in their investigations has been rather varied. The IOTN and DAI were the most frequently adopted indices [4][5]8,[10][11][13][14][16][17][18][19][20]22 , while some studies were based on the evaluation of a specific occlusal alteration [2][3]6,9,12,21,23 . The amplitude of occlusion conditions, allied to the diverse methods of measuring malocclusions has made it difficult to perform comparisons of the results of epidemiological studies.…”

“…The majority of the publications (57%) were concentrated in the last five years (12) There was diversity as regard the periodical published, however, the following periodicals: Revista Gaúcha de Odontologia, Jornal Brasileiro de Odontopediatria e Odontologia para Bebê, Community Dentistry and Oral Epidemiology, Australian Orthodontic Journal and European Journal of Orthodontics were those that allowed the largest number of articles to be located (2 in each) 6,[8][9][10][11]13,[17][18][19]21 . The other periodicals presented a uniform distribution with one article in each [2][3][4][5]12,[14][15][16]20 .…”
