AB  - Thin hydroxyapatite coatings were produced on Cp-Titanium Grade-2 samples, with new high-voltage pulse-power equipment PJ-100 (Plasma Jet, Serbia) in order to get a more stable implant structure appropriate for further clinical applications. A comparative analysis of differently prepared surfaces of the Cp-Titanium Grade-2 samples was done before the hydroxyapatite was applied. Microstructural observation of the modified hydroxyapatite/implant surface was done using scanning-electron-microscopy imaging and Auger electron spectroscopy, with the aim of detecting the morphology and the elements contained in the new surfaces of the samples. The results confirmed that the surface of Cp-Titanium Grade-2 modified with hydroxyapatite is very similar to the bone structure.

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. (C) 2014 Elsevier Ltd.

AB  - The aim of this study was to evaluate the effect of recasting of commercially available Ni-Cr (Wiron 99) and Co-Cr (Dentalit C) dental alloys on physiology of microenvironmental cells. The viability of fibrosarcoma (L929) cells, human embrional fibroblasts (MRC-5) and isolated peripheral blood mononuclear cells (PBMC) was measured by MTT and acidic phosphatase tests. Presence of dying cells was estimated by Annexin/PI staining while the production of intracellular nitric oxide (NO), reactive oxygen (ROS) and nitrogen (RNS) species was determined by DAF-FM diacetate and DHR staining. Recasting of Ni-Cr alloy intensified its cytotoxicity manifested through enhanced free radicals production, induction of cell death and permamently diminished cell proliferation. On the other hand, after initial toxic effect cells adapted to the presence of Co-Cr alloys. Independently of recasting, Co-Cr alloys are more compatible with microenvironment then Ni-Cr alloy. Oppositely, recasting of Ni-Cr alloy promoted its toxicity.
