Endodontic therapy consists in the management of several tissues such as pulp tissue, periodontal tissue, periapical bone and dentine. These tissues are often contaminated by blood, periapical exudates and biological fluids. An ideal orthograde or retrograde filling material should be non toxic, noncarcinogenic, nongenotoxic, biocompatible with the host tissues, insoluble in tissue fluids, and dimensionally stable. Calcium-silicate MTA based cements own many of these ideal characteristics, but the long setting time, the non-easy handling and the lack of mechanical properties at early times are few drawbacks which may complicate the clinical application. The aim of this study was to investigate the chemical, physical and biological properties of calcium-silicate MTA cements in order to improve the mechanical properties and the handling keeping the biological characteristics unchanged. Chemical and physical properties such as setting time, solubility, water-uptake, ion release, sealing ability were investigated according the ISO and ADA specifications. The bioactivity (ability to produce apatite nano-sferulities) of MTA cements were evaluated using ESEM/EDX, micro-Raman and ATR/FTIR spettroscopy.
