Objective: This study aimed to evaluate the contribution of demographic and clinical characteristics on the psychosocial impact of dental aesthetics of dental patients. Methods: The psychosocial impact of dental aesthetics was assessed by the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Data validity was estimated using confirmatory factor analysis (CFA). Reliability was assessed using standardised Cronbach's alpha coefficient (a). A structural model was developed to assess the contribution of demographic and clinical characteristics to the results. The fit of the model was evaluated and the z test (a = 5%) was used to estimate the significance of the contributions (b). Results: A total of 505 dental patients (80% female; age: 36.3, SD = 11.4) participated in the study. Data showed adequate validity (CFA: v 2 / df = 3.3, Tucker-Lewis index [TLI] = 0.92, comparative fit index [CFI] = 0.92 and root mean square error of approximation [RMSEA] = 0.07) and reliability (a = 0.77-0.92). The fit of the structural model was adequate (v 2 /df = 2.8, TLI = 0.89, CFI = 0.91, RMSEA = 0.06). People of a lower economic level, with incomplete dentition, who did not undergo previous aesthetic dental treatment, and who did not like their own smile showed greater psychosocial impact of dental aesthetics. Conclusions: Demographic and clinical characteristics should be considered in the evaluation of the impact of dental aesthetics on individuals'. Moreover, PIDAQ is an alternative tool for clinical evaluation of the psychosocial impact of dental aesthetics because it provides valid and reliable data.

Objetivo: Descrever o perfil nutricional dos pacientes submetidos à hemodiálise. Métodos: Estudo transversal analítico descritivo, realizado com pacientes com doença renal crônica em hemodiálise. Para classificar o estado nutricional utilizou o Índice de Massa Corporal (IMC). Foram coletados dados sócios demográficos através de questionário e exames bioquímicos no prontuário. Resultados: Foram avaliados 13 pacientes, sendo a maioria do sexo masculino (61,5%), com média de idade 47,3 anos, quanto ao diagnóstico da doença renal primária as causas mais frequentes foram diabetes e hipertensão. Ao analisar o IMC: pacientes eutroficos 38,5%, sobrepeso 38,5%, 15,3% obesos e 1 paciente desnutrido. Conclusão: Houve prevalência nos pacientes a eutrofia e sobrepeso, dois pacientes eram obesos e um desnutrido.

The aim of this study was to validity of the Portuguese version of the Clinician Attitudes Toward Biostatistics (CATB) among dentistry postgraduate students. The CATB is a psychometric instrument  four-factor. We evaluated the validity (λ, X2/df, CFI, TLI e RMSEA) and reliability (Cronbach's alpha (α) and Composite Reliability (CR)) of the instrument to the sample. It took part of the study 115 postgraduate students (62 master’s students, 80 women, average age 26 ± 4 years). The four-factor model did not fit the sample (λ=0.00-0.85, X2/df=1.83, CFI=0.85 e TLI=0.82 e RMSEA=0.09). After the fit of the refined orthogonal two-factor model (“Perceptions of Knowledge/Training” and “Perceptions of Biostatistics in Research and Scientific Evidence”) was found to be adequate (λ>0.45, X2/df≤2.00; CFI e TLI>0.90, RMSEA≤0.10, α e CR>0.70). The “Perception of Knowledge/Training of Biostatistics” factor was not found to be correlated with the “Perception of Biostatistics in Research and Scientific Evidence”.
