1. Avaliação do efeito do selenito de sódio em dentes de filhotes de ratas irradicadas / Evaluation of sodium selenite effect on offspring teeth of irradiated female rats
The aim of this study was to evaluate the sodium selenite effect on offspring molars of irradiated female rats. For this purpose, twenty pregnant female rats were used and divided into four experimental groups: control, selenium, irradiated and selenium-irradiated. The animals of the irradiated and selenium-irradiated groups received a single exposure dose o

2. Birrefringencia da matriz organica do esmalte dentario
The formation of dental enamel is a complex biological process, which depends on a well-structured organic matrix. Recent evidences indicate that the components of this matrix can interact to form a supramolecular structure. The biological significance of this supramolecular organization is not clearly understood. In part this occurs due to methodological di

3. Diagrama de fases do sistema brometo de cetiltrimetilamonio - silicato de tetrametilamonio - agua
The molecular sieves of the M41S family have been studied since their discovery in 1992, however, the mechanism of their formation is not yet very clear. In this work, a phase diagram for the system cetyltrimethylammonium bromide (CTAB)/tetramethylammonium silicate/water has been constructed, in order to obtain basic information on the interactions that exis
