ABSTRACT
ABSTRACT Introduction: The Sayers and Newton questionnaire was developed in England to assess the child's and parent's expectations about orthodontic treatment. Objective: The aim of this study was to carry out the cross-cultural adaptation of the questionnaire for the Brazilian Portuguese language, to test its reliability, and to compare patients' and their parents' expectations of orthodontic treatment. Methods: After translation and cross-cultural adaptation, the questionnaire was applied to 98 patients (12-14 years), who had been referred for treatment, and their caregivers. The internal consistency of the instrument was assessed by Cronbach's Alpha Coefficient and the test-retest reliability, by Intraclass Correlation Coefficient (ICC). Results: Internal reliability was confirmed by a Cronbach's alpha coefficient of 0.75. Test-retest reliability revealed satisfactory reproducibility (ICC = 0.85). The results showed some significant differences between the expectations of the patients and their caregivers (p < 0.05). There were no significant gender differences (p > 0.05). Conclusions: The process of cross-cultural adaptation of the Sayers and Newton questionnaire for the Brazilian Portuguese was concluded. This study demonstrated that this instrument is reliable and applicable to assess the child's and parent's expectations about orthodontic treatment in Brazil, and it has acceptable psychometric properties.
RESUMO Introdução: O questionário de Sayers e Newton foi desenvolvido na Inglaterra para avaliar as expectativas dos pacientes e de seus responsáveis quanto ao tratamento ortodôntico. Objetivo: O objetivo do presente estudo foi realizar a adaptação transcultural do questionário para a língua portuguesa do Brasil, testar sua confiabilidade e comparar as expectativas de pacientes e responsáveis em relação ao tratamento ortodôntico. Métodos: Após tradução e adaptação transcultural, o questionário foi aplicado a 98 pacientes (12-14 anos), encaminhados ao departamento de Ortodontia da PUC-MINAS para tratamento e de seus responsáveis. A consistência interna do instrumento foi avaliada pelo coeficiente alfa de Cronbach, e a confiabilidade teste-reteste, pelo coeficiente de correlação intraclasse (ICC). Resultados: A confiabilidade interna foi confirmada pelo coeficiente alfa de Cronbach de 0,75. A confiabilidade teste-reteste revelou reprodutibilidade satisfatória (ICC = 0,85). Os resultados mostraram algumas diferenças significativas entre as expectativas dos pacientes e de seus responsáveis (p < 0,05). Não houve diferenças significativas quanto ao sexo (p > 0,05). Conclusões: Foi concluído o processo de adaptação transcultural do questionário de Sayers e Newton para o português brasileiro. Esse estudo demonstrou que esse instrumento é confiável e aplicável para avaliar as expectativas dos pacientes e dos pais sobre o tratamento ortodôntico no Brasil e possui propriedades psicométricas aceitáveis.
ABSTRACT
Dentinogenesis imperfecta is a dominant autosomal hereditary disorder of dentin formation that affects the deciduous and permanent teeth. Its etiology is characterized by inadequate cell differentiation during odontogenesis. The clinical characteristics of dentinogenesis imperfecta are discolored teeth with a translucency that varies from gray to brown or amber. Radiographically, the teeth exhibit pulp obliteration, thin and short roots, bell-shaped crowns, and periapical bone rarefaction. The aim of this report was to present a case of dentinogenesis imperfecta type II that was followed up over a 17-year period. This report also presents scanning electron microscopy images of the enamel and dentin, showing that both were altered in the affected teeth. The disease characteristics and the treatments that were administered are reported in this study to guide dentists with respect to the need for early diagnosis and adequate follow-up to avoid major sequelae.
