Modelo de conductancia hidráulica de la dentina humana ex vivo

The main objective of this work was to mount and test an experimental model to measure the hydraulic conductance of ex vivo dentin. Seventeen healthy third molars, with indication of extraction of healthy donors aged between 15 and 30 years were obtained by informed consent. After cleaning them, disinfecting them, including them in resin epoxy and cutting them, there were 17 samples of dentin, corresponding to a disk of resin with a coronal section of tooth showing the dentin exposed on both sides of it. Three machines to measure the hydraulic conductance of the dentin were assembled according to the description of the model of Pashley. Samples were installed in a Chamber of diffusion, connected by using silicone tubes to a graduated transfer pipette and a 20cm water column. Through the displacement of a bubble of water in the inside of the pipette, the hydraulic conductance of each sample was measured 3 times on the 14th, 21st, 28th and 35th day post extraction. The data were tabulated and analyzed statistically. There is no SS difference in the rate of flow of a measured sample in the three machines (p=0.5937). There is no SS difference in measurements of the hydraulic conductance of 13 samples of human dentin measured in days 14, 21, 28 and 35 postextraction (p=0.0704). It is possible to mount an experimental model to study the hydraulic conductance of dentin ex vivo, based on the model of Pashley. The model seems to be reliable, but more research is needed in order to validate its reliability.

O desenho da figura humana e o TAT em adolescentes grávidas: um estudo no hospital geral

The adolescent pregnancy is a public health problem and a challenge to Psychology, that could contribute proposing health prevention actions to this population. The present study intended to investigate the psychological functioning of 10 pregnant adolescents through analysis of Human Figure Drawing (HFD) and Thematic Apperception Test (TAT). It was observed a high level of anxiety experienced by the pregnant adolescents verified in tracing, in shading and in the poverty of details, that can lead to the development of problems related to pregnancy and the relationship between the family, the adolescent and the baby. As for the TAT, the stories, in general constructed by the teenagers, were poorly structured with reduced content and a magical happy ending. It was concluded that the HFD and the TAT are discriminating and adequate to evaluate these adolescents’ psychodynamics and allow to indicate supporting preventive actions in this area.
