This study aimed to assess the percentage of articles with authors affiliated to Brazilian institutions in high-impact journals and SciELO journals and to evaluate trends in 5-year citations according to the author's affiliation and journal category. Bibliometric data were obtained using Scopus database from 1995 to 2019. Publications were selected from four journal categories: High-impact General Health (HGH), High-impact Public Health (HPH), SciELO General Health (SGH) and SciELO Public Health (SPH). The number of citations that were received five years after publication and the percentage of publications with any author affiliated to Brazil were calculated by each year. The same 146 journals were followed. There was a significant increase in percentage of articles with authors affiliated to Brazilian institutions in all sets of journals. Among HGH, there was an increasing from 0.3% to 1.5% between 1995-2019, for HPH from 1% to 3%, for SGH from 49.7% to 55.4%, and for SPH from 47.4% to 71.9%. There was a significant (p < 0.01) increase in the mean of 5-year citations in all groups and Brazilian affiliated articles increased more than average. For each 10 years, average HGH articles increased 11.9 citations and Brazilian affiliated articles 32.0 citations. The results suggest that the presence of Brazilian science is increasing, and the scientific impact has increased more than average.

The aim of this study was to test Wilson & Cleary’s conceptual model of the direct and mediated pathways between clinical and non-clinical variables in relation to oral health-related quality of life. A random sample of 578 older people was evaluated. Wilson & Cleary’s conceptual model was tested using structural equations modeling including: biological variables, symptom status, functional health, oral health perceptions, oral health-related quality of life. Oral health-related quality of life was assessed with the Oral Health Impact Profile-14 (OHIP-14). In the final model, edentulism was negatively correlated to dissatisfaction of appearance of their dental prostheses (r = -0.25). Worse functional status was correlated with poor oral health perception (r = 0.24). Being aged over 68 (r = 0.25), being a female (r = 0.39) and living in rural areas (r = 0.15) had a direct effect on the edentulism. Age had a direct effect on OHIP-14 (r = -0.15). There was an indirect effect of sex on OHIP-14 via functional status (r = 0.12). The present findings partially support Wilson & Cleary’s model framework.

The aim of this study was to investigate the dimensional structure of the Oral Health Impact Profile-14: (OHIP-14). Data was obtained from studies carried out in Rio de Janeiro (N = 504) and Carlos Barbosa (N = 872), in the State of Rio Grande do Sul, Brazil. Exploratory factor analysis (EFA) was performed to identify the latent dimensions of the OHIP-14. Confirmatory factor analysis (CFA) was carried out of both samples to compare the one-dimensional structure found by the EFA and the proposed three-dimensional structure. This factorial structure was assessed using goodness-of-fit indices. In the Rio de Janeiro study, the eigenvalue was 9.2 and this one factor explained 65.6% of total variance, while in the Carlos Barbosa study the eigenvalue was 7.9 and this one factor explained 56.6% of variance. CFA indicated an adequate fit of the one-factor model for the Rio de Janeiro study (RMSEA = 0.04; CFI = 0.98; TLI = 0.98) and for the Carlos Barbosa study (RMSEA = 0.05; CFI = 0.97; TLI = 0.97). Our findings suggest that the OHIP-14 measures one single construct.El objetivo fue investigar la estructura dimensional del Oral Health Impact Profile-14: (OHIP-14). Los individuos en las muestras provinieron de dos estudios realizados en Brasil, uno en Río de Janeiro (N = 504) y el otro en Carlos Barbosa, Río Grande do Sul (N = 872). Un análisis factorial confirmatorio (AFC) se llevó a cabo para identificar las dimensiones latentes del OHIP-14 y comparar un modelo de estructura unidimensional con un modelo de tres dimensiones. La estructura dimensional fue evaluada a través de índices de calidad de ajuste. La estructura con un factor presentó, en el estudio de Río de Janeiro, un autovalor de 9,2 y esta estructura explicó un 65,6% de la variancia total, mientras que en el estudio de Carlos Barbosa el autovalor fue de 7,9 y esta estructura unidimensional explicó un 56,6% de la variancia total. El AFC realizado indicó un ajuste adecuado para el modelo de 1 factor en el estudio de Río de Janeiro (RMSEA = 0,04; CFI = 0,98; TLI = 0,98) y en el estudio de Carlos Barbosa (RMSEA = 0,05; CFI = 0,97; TLI = 0,97). El modelo de un factor fue más parsimonioso. Nuestros resultados sugieren que el OHIP-14 sea un instrumento unidimensional.O objetivo foi investigar a estrutura dimensional do Oral Health Impact Profile-14: (OHIP-14).
