Validation of the Brazilian versions of two inventories for measuring oral health-related quality of life of edentulous subjectsObjectives: To analyse the validity of the Brazilian versions of OHIP-EDENT and GOHAI as assessment tools of edentulous subjects' OHRQoL. Background: Inventories for measuring oral health-related quality of life (OHRQoL) are important in clinical studies regarding oral rehabilitation. However, there is a need for comprehensive validation after translation into different cultural settings. Materials and methods: The sample comprised of 100 complete denture wearers (29 men, 71 women, mean age of 65.2 ± 9.9 years). The associations between each OHRQoL inventory and other variables served as measurements of construct validity. Data analysis comprised the Spearman correlation test as well as multiple regression using the OHRQoL inventories as dependent variables and the other scales as determinants. Results: Both OHRQoL inventories showed good correlation with denture satisfaction, whereas lower correlation coefficients were found among the inventories and the HAD subscales. Denture satisfaction alone explained 48% and 39% of the variance found for the OHIP-EDENT and GOHAI, respectively, as assessed by multiple regression. A smaller effect was found for OHIP-EDENT. Conclusion: Both OHIP-EDENT and GOHAI showed good construct validity for measurement of OHRQoL of edentulous subjects.

The purpose of this study was to evaluate dimensions of adult human maxillary sinuses on panoramic radiographs and their possible application on the sex determination for forensic purposes. The sample comprised 64 database panoramic radiographs from individuals aged 20 years or older (32 male and 32 female subjects), with complete permanent dentition (or absence of third molars). One examiner measured the width and height of the right and left maxillary sinuses using the software Image J 1.47v (National Institutes of Health, Bethesda, USA). Measurements were repeated to calculate intra-observer agreement. Chi-Square test, Kappa, ANOVA and T-Student were used for results analysis for p≤ 0.05. Intra-observer agreement with correlation Kappa ranged between 0.38 and 0.96. For female subjects, the mean height and width of the left maxillary sinus were 28.7856mm and 44.6178mm, respectively. And right maxillary sinus was 27.7163mm for height and 45.1850mm for width. Male subjects were found to have the mean height and width of the left maxillary sinus 30.9981mm and 48.7753mm, respectively. And right maxillary sinus was 30.7403mm for height and 48.5753mm for width. There was a statistically significant difference in the height and width of maxillary sinuses between males and females. It can be concluded that maxillary sinuses height and width on panoramic radiographs can be used to determine the gender of adult human subjects.

A análise da impressão labial, conhecida como queiloscopia, pode ser útil em casos específicos de investigação forense. Este trabalho experimental teve como objetivos principais investigar a precisão na análise dos tipos de sulcos labiais, da espessura labial e da localização da comissura labial e observar diferenças estatísticas entre a classificação labial e o sexo dos indivíduos. A amostra foi composta por 100 voluntários. Foi realizada a mensuração da espessura labial com paquímetro, análise visual da comissura labial e classificação dos sulcos labiais por meio de sua impressão, sendo testada a concordância intra- e inter-observador (três avaliadores) pela reavaliação de 30% da amostra. Os resultados mostraram que é possível realizar a classificação das análises labiais, sendo que o tipo de lábio mais frequente encontrado foi o tipo I (34,25%). Em relação à espessura, o tipo misto, e a comissura do tipo abaixada, foram as predominantes, com 66% e 59% respectivamente. Além disso, observou-se que não houve diferença estatística entre os indivíduos do sexo masculino e feminino nas classificações estudadas. Em relação à precisão ao fazer as classificações as técnicas utilizadas foram consideradas aplicáveis pelos pesquisadores, uma vez que a classificação foi possível e a concordância observada foi de forte a moderada, exceto em um dos quadrantes da classificação da impressão labial
