Self-perception and malocclusion and their relation to oral appearance and function

Abstract

The aim of this study was to evaluate the relationship between malocclusion and self-perception of oral appearance/function, in 12/15-year-old Brazilian adolescents. The cluster sample consisted of 717 teenagers attending 24 urban public (n=611) and 5 rural public (n=107) schools in Maringá/PR. Malocclusion was measured using the Dental Aesthetic Index (DAI), in accordance with WHO recommendations. A parental questionnaire was applied to collect information on esthetic perception level and oral variables related to oral health. Univariate and multiple logistic regression analyses were performed. Multiple logistic regression confirmed that for 12-year-old, missing teeth (OR=2.865) and presence of openbite (open occlusal relationship) (OR=2.865) were risk indicators for speech capability. With regard to 15-year-old, presence of mandibular overjet (horizontal overlap) (OR=4.016) was a risk indicator for speech capability and molar relationship (OR=1.661) was a risk indicator for chewing capability. The impact of malocclusion on adolescents' life was confirmed in this study. Speech and chewing capability were associated with orthodontic deviations, which should be taken into consideration in oral health planning, to identify risk groups and improve community health services.

Aspectos sociodemográficos relacionados à gravidade da maloclusão em crianças brasileiras de 12 anos

“…Estudos prévios realizados no Brasil têm demostrado que as crianças brasileiras, em sua maioria, demonstraram estar satisfeitas com suas condições de saúde bucal, como aqueles realizados em Caruaru-PE 31 e Aracaju-SE 32 . Um estudo conduzido em Maringá-PR entre escolares (12 a 15 anos) identificou que a presença de problemas oclusais, avaliados a partir dos itens que compõem o DAI, mantiveramse associados a uma pior percepção da fala e da mastigação 33 , fatores estes que podem compor a auto percepção da saúde bucal. A associação entre a presença de maloclusão e a auto avaliação negativa da saúde bucal também foi identificada entre adolescentes japoneses 34 , porém utilizando outro critério de diagnóstico.…”

Malocclusion and deleterious oral habits among adolescents in a developing area in northeastern Brazil

“…These results agree with the literature in which a rate of 82.1% to 91% has been reported. [1][2][3][4][10][11][12] Normal occlusion was mainly observed in girls, whereas Class I and III MO were more common among boys. Other authors have also observed differences between genders in the arrangement of the permanent first molars.…”

“…[1][2][3][4] Various studies have investigated the frequency and distribution of MO in young permanent dentition, [3][4][5] but the use of different methods and indicators impairs the comparison of these results. Thus, the World Health Organization (WHO) recommends the use of the Dental Aesthetic Index (DAI) to standardize epidemiological data on MO.…”

“…Com isso, ações de controle de modificações na aparência bucal tem sido alvo de estudos por parte da epidemiologia, com base em vários indicadores de saúde bucal, preconizados pela Organização Mundial de Saúde (OMS) com o intuito de tentar minimizar consequências psicológicas em crianças e adolescentes, a partir do conhecimento dos principais fatores de risco para desenvolvimento de enfermidades bucais e deformações dento-ósseas 1 .…”
