AB  - The aim of this study was to synthesize and characterize new superplastic endodontic mixtures (named as ALBO-MPSA) with strongly accelerated hydration rate. Two different ALBO-MPSA mixtures were prepared using combination of hydrothermal and high-temperature self-propagating method. Phase analysis of the mixtures, before and after hydration, was carried out by X-ray diffraction (XRD), while morphological analysis was performed by scanning electron microscopy (SEM). Investigations of mechanical properties showed that new superplastic, quick-bonding endodontic mixtures with good mechanical properties were obtained (compressive strength after 28days aging was from 35.7 +/- 0.5 and 37.4 +/- 0.5 MPa). The final phase compositions after hydration of the mixtures were determined on the base of XRD data, assumed mechanism of hydration and rational chemical analysis. The constitutive phases were tobermorite, portlandite, and amorphous Ca(OH)(2), ettringite and amorphous like ettringite phase, gypsum, hydroxyapatite and barite.

AB  - In this research, the structure changes along the depth gradient layers of titanium substrate, after etching with NaOH and subsequent thermal treatment at various temperatures between 300 and 800 degrees C, were investigated by XRD, FTIR and AES. Particularly, the changes of Ti substrate after etching with NaOH, subsequent ionic exchange of Na+ with Ca2+ ions and thermal treatment at 700 degrees C were analysed. Due to this approach, it was possible to get insight into the chemical changes and changes of Ti oxidation states and consequent phase analysis, along the depth of the titanium oxide coatings. In addition, Secondary Electron Imaging (SEI) showed very interesting nanotopology of all samples. Particularly interesting topology, consisting of very thin nano-designed walls between mutually interconnected pores, was observed for the sample in which Na+ were replaced with Ca2+ ions. This structure might be suitable for deposition of hydroxyapatite by biomimetic or plasma methods and as an appropriate scaffold for cell adhesion and proliferation.

AB  - In this paper, the kinetics and sintering mechanism of hydro-thermally synthesized hydroxyapatite in the temperature range 900-1100 degrees C are presented. It was found that at 900 degrees C, the sintering process is very slow, whereas at 1000, 1050, and 1100 degrees C is much faster, caused by activated sintering with liquid phase/phase of solution on spots with concentrated material impurity and the formation of reaction/polyeutectic mixtures dominates. The activation energies of sintering were also determined. At all the investigated sintering temperatures, an approximate value of 90 kJ mol(-1) was found.
