1. Estudo in-vitro dos efeitos do laser de Er,Cr:YSGG em tecido ósseo por espectroscopia ATR-FTIR / Study in vitro of Er,Cr:YSGG laser effects in bone tissue by ATR-FTIR spectroscopy
Laser proves to be, more and more, an effective tool for helping health professionals, being intensively used in ophthalmological and odontological procedures. In particular, high-density, infrared emitting lasers have great potential in cutting mineralized biological hard tissues, given their high absorption by hydroxyapatite and water, these tissues main c

2. Análise mecânica e microestrutural das ligas de cobalto-cromo de uso odontológico após sucessivas refundições
The cobalt-chromium alloy is extensively used in the Odontology for the confection of metallic scaffolding in partial removable denture. During the last few years, it has been reported an increasing number of premature imperfections, with a few months of prosthesis use. The manufacture of these components is made in prosthetic laboratories and normally invol

3. CORROSION OF ADVANCED STAINLESS STEEL IN PHYSIOLOGICAL SOLUTIONS / Corrosão de aços inoxidáveis avançados em meios fisiológicos
The main objective of this study was to determine the corrosion behavior of advanced stainless steels (SS) in physiological solutions to evaluate their potential for use as biomaterials. Four stainless steels were tested: a superferritic stainless steel (DIN W. Nr. 1.4575), Incoloy MA 956, containing aluminum and yttrium oxide, an austenitic stainless steel

4. SÍNTESE E CARACTERIZAÇÃO DE ÓXIDOS COM BAIXA EXPANSÃO TÉRMICA / SYNTHESIS AND CHARACTERIZATION OF LOW THERMAL EXPANSION OXIDES
Negative and low thermal expansion materials have important potential applications as resistance to thermal shock, as well as, for odontological applications, printed circuit boards, optical components and to produce composites to compensate the positive thermal expansion of materials. For this reason, the study and production of materials with controlled th

6. Influencia do numero de coccões sobre a rugosidade superficial da porcelana odontologica
In view of the advance of Odontology in carrying our the rehabilitation of a lost dental structure, through the use of some aesthetic restorative materials and also due to some controversies among the authors about the best way to achieve this, we proposed to study some technical variables of odontological porcelain used in metal-ceramics ...Note: The comple
