13. Polymerization shrinkage evaluation of an universal light curing composite resin, varying the placement techniques, measured by gas pycnometer / "Avaliação da contração de polimerização de uma resina composta fotopolimerizável de uso universal, variando-se a técnica de inserção do material medida por picnômetro a gás"
Because of its versatility and aestetic excellency, composite resin is one of the most utilized direct restorative materials. Because of the resin intense use, the number of researches to improve its performance are numerous, and can be verified by the resin aestethetic behavior and its compressive and abrasion strenght increase. In spite of the mentioned de

14. Estudo do comportamento resiliente de três solos da região de Campo Grande-MS e de relações entre o módulo de resiliência e resultados de ensaios de compressão simples / Study of the resilient behavior of three soils from Campo Grande-MS and analysis of relations among resilient modulus and results of compressive strenght tests
The resilient modulus knowledge (MR) is fundamental for pavement design, once it is necessary for stresses, strains and deflections calculus in its layers and subgrade, as well as, the analysis of system performance. Although field tests may be used to determine the dynamic behavior of soils, most of researchers favor laboratory tests, based on the fact that

15. Efeito da esterilização em autoclave sobre propriedades mecanicas das miniplacas de titanio, utilizadas em fixação internas
Titanium plates and screws are used for fixation of facial fractures and orthognatic surgery. That material is kept on proper boxes and receives multiple autoclave sterilization cycles. The present study evaluates the effects of those cycles upon mechanical properties of titanium miniplates (system 2.0, (Engimplan). For that task four groups of fifteen plate

16. Influencia do tempo de armazenagem sobre a dureza superficial e a resistencia a compressão de cimentos ionomericos restauradores
The purpose of this work was to verify the superficial microhardness and the compressive strenght of VIDRION R (SS WHITE) and VITREMER (3M) glass ionomer cements, Type II, stored at 37°C and 100 % relative humidity for 15 minutes, 1 hour and 24 hours. For the superficial microhardness test were made five samples from each material, in temperature (23 + OU

17. Avaliação da resistencia a fratura de raizes debilitadas reconstruidas morfologicamente com materiais adesivos
Several dental roots extractions have been indicated due to carie, incorrected intra-root preparations, remotions of pin and post. The aim of this research was to evaluate the resistence fracture of debilitated root filled with adhesive materials. Unirradicular with cast and cemented post were utilized in the following conditions: positive control (conventio
