Abstract

The researcher was involved for three years in research on calcium aluminate cement (CAC) under supervision of Dr. Victor Pandolfelli. Among the topics addressed by the research may be cited: the knowledge about the chemical nature of hydration process and the additives incorporation to CAC. Furthermore, its knowledge acquired in previous research involving processing, suspension dispersion and correlation with the properties of ceramic material, encouraged the first tests for novel application of CAC as dental restorative material. Physico-chemical and biological preliminary tests using CAC resulted in a patent in which Professor Dr. Pandolfelli and Dr. Ivone participated as inventors and four technical articles were written. Thus, the aim of this work is to continue the research on CAC as biomaterial by systematic physico-chemical study on this material. This way it can be possible to acquire deep knowledge about its synthesis, processing and properties in the presence of different additives and compounds as well as when in contact with biological fluids. As a result of this work, it is expected that compositions with appropriate characteristics for biological applications can be proposed to overcome the qualities and some negative properties presented by current available materials. The development of this work has a prestigious partnership with the GEMM-UFSCar, coordinated by Dr. Pandolfelli. However, the responsible researcher has started her career at the University of Vale do Paraíba. The aid of FAPESP to this proposal is essential for enhancement of this important emerging center in research that can offer to the market a new generation of biomaterials. (AU)
