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
To investigate the prevalence of dental trauma, its causes, sites and age at the occurrence of injuries and treatment needs related to dental trauma in schoolchildren aged 12 years at Brasília, DF, Brazil.Material and Methods:A cross-sectional, population-based study was conducted on a sample of 1,389 schoolchildren of public and private schools. Two questionnaires were used: one targeted to parents/legal caretakers and the other responded by the schoolchildren. The criteria for classification of trauma used in the ChildrenÆs Dental Survey in the United Kingdom were adopted. The examinations were performed by two trained and calibrated examiners (inter and intra-examiner kappa: 0.85 to 1.00). The association between dental trauma and the study variables was evaluated by the chi-square test.Results:A total of 1,445 students were examined, with a response rate of 80.48%. Prevalence of 14.63% (public schools) and 23.40% (private schools) of dental trauma was found...(AU)
The most common cause of dental trauma was fall (7.87%), followed by collision with objects or persons(5.03%), inadequate use of the teeth (2.33%), sports accidents (2.11%) and car accidents (0.66%). It was observed that 256 students presented injury to at least one tooth, with predominance of enamel fracture (88.67%) followed by discoloration (5.47%), enamel and dentin fracture (3.90%) and tooth loss (1.95 %). The teeth most affected by trauma were the maxillary central incisors. The accidents occurred predominantly at home (44.25%) and at the school (26.99%). Only 28.51% had received treatment for the injuries.Conclusion:Dental trauma in the study population was significant, presenting diverse etiology and expressive treatment needs, indicating the importance of preventive programs to inform the population on the possible complications after trauma, as well as the need to follow-up traumatized teeth to avoid subsequent problems...
