The aim of this study was to determine the level of agreement between reports by adolescents and their mothers regarding the impact of oral health on the adolescents' quality of life. The sample consisted of 960 pairs of adolescents aged 11 to 14 years and their mothers. The Brazilian version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ) and the short form of the Child Perceptions Questionnaire (CPQ11-14) were administered. Agreement on the total scale and the subscales was determined through a comparison of mean values. The means of the directional and absolute differences were also determined. Agreement on each item on the group level and in the individual pairs was analyzed using the Intraclass Correlation Coefficient (ICC). The difference between the means and the directional differences were significant for the total score as well as for the functional limitation and social well-being subscales (p < 0.001). The ICC for the total P-CPQ and CPQ11-14 scores was 0.43. The ICC indicated weak agreement on the subscales, ranging from 0.36 to 0.40. Agreement between reports by adolescents and their mothers regarding oral health-related quality of life (OHRQoL) was moderate, indicating that both perspectives should be considered.

O Parental-Caregiver Perceptions Questionnaire (P-CPQ) é um instrumento que avalia a percepção do pai/responsável a respeito do impacto da saúde bucal da sua criança na qualidade de vida da mesma. O objetivo do estudo foi avaliar as propriedades psicométricas da versão brasileira do P-CPQ. Após a tradução e adaptação transcultural, o P-CPQ foi testado em uma amostra de 123 pais/responsáveis de crianças com idade entre 11-14 anos com cárie dentária e maloclusão. Os pais/responsáveis foram selecionados das clínicas dentárias da Universidade Federal de Minas Gerais, onde as crianças recebiam atendimento odontológico. As propriedades psicométricas foram avaliadas através da consistência interna, confiabilidade teste-reteste, validade de constructo e validade discriminante. O escore médio do P-CPQ foi 13,01 (dp=12,14) para o grupo com cárie dentária e 16,57 (dp=13,13) para o grupo com maloclusão. A consistência interna foi confirmada pelo coeficiente alfa de Cronbach de 0,84. A confiabilidade teste-reteste revelou satisfatória reprodutibilidade (ICC=0,83). A validade de constructo foi satisfatória, demonstrando correlações significativas entre os indicadores globais e a escala total. O escore do P-CPQ foi capaz de discriminar diferentes percepções dos pais/responsáveis sobre as condições bucais de suas crianças (cárie dentária e maloclusão). Os resultados da versão brasileira do P-CPQ confirmam ser este um questionário válido e confiável.

The Parental-Caregiver Perceptions Questionnaire (P-CPQ) is an instrument that assesses a parent's or a caregiver's perceptions regarding the impact of children's oral health status on quality of life. The aim of this study was to evaluate the psychometric properties of the Brazilian version of the P-CPQ. Following translation and cross-cultural adaptation, the P-CPQ was tested on 123 parents and caregivers of children between 11 and 14 years of age with dental caries and malocclusions. The parents/caregivers were recruited at dental clinics of the Federal University of Minas Gerais, where their children were receiving dental care. Psychometric properties were assessed through internal consistency, test-retest reliability, construct validity and discriminant validity. The mean P-CPQ score was 13.01 (SD=12.14) for the dental caries group and 16.57 (SD=13.13) for the malocclusion group. Internal reliability was confirmed by a Cronbach's alpha coefficient of 0.84. Test-retest reliability revealed satisfactory reproducibility (ICC=0.83). Construct validity was satisfactory, demonstrating significant correlations between global indicators and the total scale. The P-CPQ score was able to discriminate between different parental/caregiver perceptions of oral conditions in their children (dental caries and malocclusion). The results for the Brazilian version of the P-CPQ confirm that this questionnaire is a reliable and valid instrument to assess parental perceptions on the impact that oral health status has on children's life quality.

Este estudo teve como objetivo verificar o perfil dos pesquisadores de Odontologia, bolsistas de produtividade em pesquisa, do Conselho Nacional de Desenvolvimento e Pesquisa (CNPq). A coleta dos dados foi realizada em março de 2008, a partir da base de dados do curriculum vitae (Plataforma Lattes). Observou-se que estavam registrados 144 pesquisadores vinculados a 25 instituições brasileiras de ensino e pesquisa. Esses pesquisadores publicaram um total de 12.997 artigos completos, sendo 6.927 produzidos nos últimos 5 anos. Os bolsistas da categoria 1 (n=77) foram responsáveis por 53,5% dessa produção, os da categoria 2 (n=65) por 45,1% e os bolsistas seniores (n=2) por 1,4%. Em relação ao vínculo institucional, 90,3% dos pesquisadores bolsistas desenvolvem suas atividades em instituições públicas e 9,7% em instituições privadas. Observou-se ainda que 84,0% dos pesquisadores estão vinculados a instituições localizadas na região sudeste do Brasil, sendo que do total dos pesquisadores, 75,0% atuam no Estado de São Paulo. Este estudo demonstrou a importante contribuição dos bolsistas para a produção científica da área. Ademais, possibilitou o mapeamento da distribuição desses pesquisadores, evidenciando a concentração dos mesmos na região sudeste do país, especialmente no Estado de São Paulo.

The present study analyzed the profile of dental researchers receiving grants related to their productivity in research from the Brazilian National Research and Development Council (CNPq). Data collection was carried out in March 2008, using the Brazilian database for curriculum vitae (Lattes Format). There were 144 researchers registered in the database and linked to 25 institutions. These researchers published a total of 12,997 full-text articles, 6,927 of which were published in the last 5 years. Category 1 grant holders (n=77) were responsible for 53.5% of this production; Category 2 grant holders (n=65) were responsible for 45.1%; Senior grant holders (n=2) were responsible for 1.4%. Regarding institutional affiliation, 90.3% of the research grants holders develop activities at public institutions and 9.7% develop activities in private institutions. Furthermore, 84.0% of the researchers are linked to institutions located in the southeast region of Brazil and 75.0% of the researchers perform their activities in the state of São Paulo. This study performed a mapping of the distribution of CNPq researchers, revealing a concentration in the southeast region of the country, especially in the state of São Paulo. The findings of the present study also demonstrate the important contribution of grant holders to the scientific production in dentistry in Brazil.
