AB  - Aim: The use of nitinol archwires (NiTi) in orthodontic treatment has expanded significantly due to unique
mechanical properties such as shape memory effect and superelasticity. The greatest barrier to safe
application of NiTi archwires is microbiologically or electrochemically induced corrosion. Corrosion of NiTi
archwires result in Ni2+ release, leading to different health implications. The purpose of this investigation is
the improvement of NiTi archwires properties by synthesis of multilayerd, firmly bonded nanocoatings with
antibacterial properties using the magnetron sputtering (MS). These nanocoatings will enhance corrosion
resistance and decrease cytotoxic properties by preventing Ni2+ release, without compromising mechanical
characteristics of the conventional NiTi archwires. Materials and Method: The nanocoatings of TiO2, TiN,
TiN+Cu were acquired by pulsed magnetron sputtering using the commercially available nickel-titanium
archwires. The samples were assessed using atomic force microscopy and X-ray diffraction. Inductively
coupled plasma - optical emission spectrometry was used to estimate the release of Ni, Ti, Cu, Fe, Cr, Zn
ions into DMEM and acidic solution. Biocompatibility of samples' eluates was investigated using Neutral red
staining. Disk Diffusion Method was used for assessing the antibacterial properties against bacterial
suspensions of Streptococcus mutans. Results: Compared to NiTi and stainless steel, the nonocoated
archwires showed statistically lower release of nickel both in DMEM and acidic environment (p<0.05).
Regarding the relative cell viability, the 7-day eluates of nanocoated archwires was the highest (p<0.05).
Antibacterial activity of nanocoated archwires was statistically significant in comparison to the conventional
NiTi and stainless steel archwires (p<0.05). Conclusions: As nanocoated archwires presented desired
antibacterial properties with better stability in both acidic and non-acidic conditions, as well as satisfactory biocompatibility, they may be a good candidate for further clinical investigations.

AB  - Objectives: The main purpose of orthodontic treatment (OT) is to accomplish an optimal occlusal relationship in order to obtain adequate oral function and aesthetic appearance. Under optimal economic conditions, demand for OT reaches at least 35%, but in higher socioeconomic areas in US more than 50% of children are receiving orthodontic care. Acceptance of OT in Europe, like in western population and Scandinavian countries, is at similar levels. Very desirable mechanical characteristics, such as shape memory effect and superelasticity, expanded the use of nitinol (NiTi) archwires in orthodontics significantly. The complex conditions present in the oral cavity, including biofilm formation on the exposed surfaces, substantially alter the surface and structural properties of the NiTi archwires compromising the safety of OT. The necessity for developing novel material coating that would decrease Ni release and improve biological properties is of a great importance. Materials-Methods: Copper doped titanium nitride films (TiN-Cu) on the surface of NiTi archwires were obtained by combination of the cathodic arc evaporation and DC magnetron sputtering. The physicochemical characterization was performed using energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). Ion release was assessed using inductively coupled plasma optical emission spectrometry (ICP-OES). The cytotoxicity of NiTi archwires, stainless steel (SS) archwires and TiN-Cu coated archwires was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyl tetrazolium bromide (MTT) test. In order to evaluate bacterial adhesion and biofilm formation, the following strains were used: Streptococcus mutans and Streptococcus mitis. Results: Physicochemical characterization revealed well-designed coatings with the presence of TiN phase with incorporated Cu. The release of Ni was the lowest regarding TiN-Cunanocoated archwires (p < 0.05) and increased in acidic conditions, while the release of Ti was constant. Contrary, the release of Cu was higher in neutral conditions and decreased during the observation time (p < 0.05). The cytotoxicity was the lowest in 28-day eluates of TiN-Cu-nanocoated archwires (p < 0.05). The coating inhibited the adhesion and growth of bacteria such as Streptococcus mitis and Streptococcus mutans (p < 0.05). Conclusion: Taking into account the results of cytotoxicity test and biofilm formation, TiN-Cunanocoated archwires may be considered as a good candidate for further clinical investigations.

AB  - Magnesium (Mg) is an essential element in the human body primarily stored in bones. Mg ions have many potential benefits for bone tissue showing excellent osteogenic inductivity [1]. The aim of this study was to synthesize Mg substituted hydroxyapatite (Mg-HAP) for application in bone tissue engineering and to assess its behaviour in conditions mimicking physiological ones. Mg-HAP was synthesized using reflux method and its structural and morphological characterization was performed by XRD, FTIR and SEM. The changes in local structure and composition after irradiation and immersion in physiological solution and simulated fluid were assessed by electron paramagnetic resonance (EPR) spectroscopy. The results of EPR analysis pointed out that irradiation did not change the composition and structure of Mg-HAP. After immersion in model media (simulated body fluid and saline solution), the small amount of by-product of synthesis disappeared after 24 h and Mg-HAP remained the only phase. Also, the radical signals in EPR spectra faded away after 28 days in model media, showing that the structure and composition of Mg-HAP both went through a kind of stabilization in simulated physiological conditions. These results make the investigated Mg-HAP promising material for application in bone tissue engineering.

AB  - To enhance endodontics, the search for new antibacterials that can improve infected tooth root canal treatment is ongoing. As potent antibacterial and antibiofilm agents, essential oils (EOs) have been suggested as novel endodontic materials. Several studies indicate that EO-based irrigants and medicaments show promising reductive potential against the most important intracanal pathogen, Enterococcus faecalis, and notably contribute to intracanal biofilm eradication. In terms of additional benefits that EO-based endodontic materials can provide, their antioxidant and anti-inflammatory potential are also important, but they have only scarcely been explored in research. Investigations into the benefits of EO-based endodontic materials together with their biocompatibility are needed. The results presented in this review strongly encourage further research on this topic.

AB  - To assess the application potential of novel biomaterials, their behaviour in model media and upon sterilization should be investigated, as well as the stability related to their storage condi-tions. Such data are lacking for Mg-substituted HAP (Mg-HAP). Therefore, the changes in the local structure of non-substituted and Mg-HAP after irradiation and immersion in corrected simulated fluid and saline solution for 28 days were followed by electron paramagnetic resonance (EPR) spectroscopy for the first time. To better understand the stability of radical species induced by steriliza-tion, EPR spectra of samples kept for 2 h at temperatures up to 373 K were recorded to provide an insight into the stability of the sample storage conditions by the accelerated aging method. Samples were characterized by PXRD, FTIR, SEM, EDS, AAS and TGA. Results confirmed that irradiation does not induce changes in the composition or the structure of any of the investigated materials. Fading or the complete disappearance of radical signals in the EPR spectra after immersion in both media was accompanied by the disappearance of other phases formed as a minor byproduct in the synthesis of substituted HAP, as confirmed by PXRD and FTIR analysis. Obtained results confirm the great potential of Mg-HAPs for biomedical applications, although closer attention should be given to the processes related to sample storage stability at different temperatures. © 2022 by the authors.

AB  - As magnesium is an important trace element in bone and teeth, and plays a key role in bone metabolism, the aim of this study was to obtain magnesium substituted hydroxyapatite (MgHAP) and to assess its application potential. Upon synthesis, the changes in local structure and composition after irradiation and immersion in physiological solution and simulated fluid were followed by electron paramagnetic resonance (EPR) spectroscopy. Samples were also characterized by XRD, FTIR, SEM, EDS, AAS and TGA. The results showed that irradiation did not affect the composition and structure of Mg-HAP. After immersion in model media, the small amount of by-product of synthesis disappeared already after 24 h and Mg-HAP remained as the only phase. Also, the radical signals in EPR spectra faded or completely disappeared after 28 days in model media, which could indicate that the structure and composition of Mg-HAP both went through a kind of stabilization in conditions mimicking physiological ones. All these indicate that investigated Mg-HAP has good potential for biomedical application considering its behaviour in model media which imitate physiological conditions.

AB  - Due to its similarity with biological apatite found in vertebrate hard tissues, calcium hydroxyapatite is one of the most investigated materials in bone tissue engineering. As the biological apatite is not stoichiometric, ion substituted hydroxyapatites attract much atention since they more closely mimic the composition of natural bone. Although there are many investigations of the influence of foreign ions on the structure and physico-chemical properties of ion-substituted hydroxyapatites, there is scarse information on their behaviour in different media. In the present study, magnesium (Mg), that plays a key role in bone metabolism and silicon (Si), that is necessary for normal skeletal development, were used as ion substitutes. The behaviour of Mg and Si substituted hydroxyapatite in simulated body fluid was investigated by XRD, FTIR and SEM. Obtained results confirmed great potential of these substituted hydroxyapatites for biomedical applications.

AB  - Background/Aim. The materials used nowadays for bone replacement do not fully meet the requirements for complete regeneration, which is why new ones are being tested. Despite numerous attempts to improve bone tissue regeneration, no fulfilling material has been found yet. This study investigated the influence of poly-lactide-co-glycolide (PLGA) and polyethyleneimine (PEI) as coatings for hydroxyapatite (HAP) bone carriers on bone tissue regenerative potential in rabbits? calvarial defect. Methods. Calvarial defects measuring 6 mm in diameter were made in 19 skeletally mature rabbits. Defects were filled with one of the following materials: PLGA coated HAP (HAP + PLGA), PEI coated HAP (HAP + PEI), and bovine HAP ? Bio-Oss? (positive control). Unfilled defects represented negative control. Histological analysis was performed in order to determine the inflammatory response of the host tissue. The formation of the new bone was evaluated using histomorphometric analysis. All analyses have been conducted in samples obtained 3, 6, and 9 weeks after implantation. Results. Three weeks post-implantation, a trend toward increased healing in the HAP + PLGA group compared to other investigated materials was noticed, with no statistically significant difference between the study groups (p > 0.05). However, after 6 and 9 weeks, significant healing was observed in favor of the HAP coated with PLGA compared to other groups (p
AB  - Uvod/Cilj. Materijali koji se u današnje vreme koriste za nadoknadu koštanog tkiva ne dovode do kompletne regeneracije, zbog čega se ispituju novi. Uprkos mnogobrojnim pokušajima da se poboljša regeneracija koštanog tkiva, još uvek nije pronađen materijal koji ispunjava sve kriterijume. Cilj rada bio je da se utvrdi uticaj poli(laktid-ko-glikolida) (PLGA) i polietilenimina (PEI), kao premaza za oblaganje hidroksiapatita (HAP), na regenerativni potencijal koštanog tkiva u defektu kalvarije zeca. Metode. Kod 19 zečeva „zrelog” skeleta načinjeni su defekti kalvarije dijametra 6 mm. Defekti su potom ispunjeni jednim od sledećih materijala: HAP obložen PLGA (HAP + PLGA), HAP obložen PEI (HAP + PEI) i goveđi HAP – Bio-Oss® (pozitivna kontrola). Prazni defekti su predstavljali negativnu kontrolu. Inflamacijska reakcija tkiva domaćina je ispitana histološkom analizom. Formiranje nove kosti je procenjivano histomorfometrijskom analizom. Analizirani su uzorci dobijeni 3, 6 i 9 nedelja nakon implantacije. Rezultati. Tri nedelje nakon implantacije, uočena je tendencija boljeg zarastanja u HAP + PLGA grupi, bez statistički značajne razlike između ispitivanih grupa (p > 0.05). Međutim, 6 i 9 nedelja nakon implantacije, primećeno je značajno formiranje koštanog tkiva u korist HAP + PLGA grupe (p < 0,05). Oblaganje HAP sa PLGA dovelo je do boljeg koštanog zarastanja u poređenju sa HAP+PEI i Bio-Oss®. Zaključak. U pogledu stimulisanja osteogeneze u rekonstruktivnoj hirurgiji kostiju, PLGA je pokazao veći potencijal prekrivanja defekta od PEI.

Cilj rada bio je da se utvrdi uticaj poli(laktid-ko-glikolida) (PLGA) i polietilenimina (PEI), kao premaza za oblaganje hidroksiapatita (HAP), na regenerativni potencijal koštanog tkiva u defektu kalvarije zeca. Metode. Kod 19 zečeva „zrelog” skeleta načinjeni su defekti kalvarije dijametra 6 mm. Defekti su potom ispunjeni jednim od sledećih materijala: HAP obložen PLGA (HAP + PLGA), HAP obložen PEI (HAP + PEI) i goveđi HAP – Bio-Oss® (pozitivna kontrola). Prazni defekti su predstavljali negativnu kontrolu. Inflamacijska reakcija tkiva domaćina je ispitana histološkom analizom. Formiranje nove kosti je procenjivano histomorfometrijskom analizom. Analizirani su uzorci dobijeni 3, 6 i 9 nedelja nakon implantacije. Rezultati. Tri nedelje nakon implantacije, uočena je tendencija boljeg zarastanja u HAP + PLGA grupi, bez statistički značajne razlike između ispitivanih grupa (p > 0.05). Međutim, 6 i 9 nedelja nakon implantacije, primećeno je značajno formiranje koštanog tkiva u korist HAP + PLGA grupe (p < 0,05). Oblaganje HAP sa PLGA dovelo je do boljeg koštanog zarastanja u poređenju sa HAP+PEI i Bio-Oss®. Zaključak. U pogledu stimulisanja osteogeneze u rekonstruktivnoj hirurgiji kostiju, PLGA je pokazao veći potencijal prekrivanja defekta od PEI.",

AB  - Thanks to its similarity with biological apatite found in vertebrate hard tissues,
calcium hydroxyapatite is one of the most investigated materials in bone tissue
engineering. Since biological apatite is not stoichiometric, ion substituted
hydroxyapatites are in the focus of many studies as they more closely mimic the
composition of natural bone. Although there are many investigations of the
influence of foreign ions on the structure and physico-chemical properties of ionsubstituted hydroxyapatites, there is no much information on their behaviour in
different media.
In present study, magnesium - which plays a key role in bone metabolism and
silicon - which is necessary for normal skeletal development, were used as ion
substitutes. The behaviour of Mg and Si substituted hydroxyapatite in simulated
body fluid and physiological solution was investigated by XRD, FTIR and SEM.
Obtained results confirmed great potential of these substituted hydroxyapatites for
biomedical applications.

AB  - The effects of a new material based on hydroxyapatite and calcium silicates, named ALBO-MPCA, were investigated on the liver, kidney and spleen. The material was administrated orally for 120 days in an in vivo model in Wistar rats, and untreated animals served as a control. Hematological and biochemical blood parameters were analyzed. Qualitative histological analysis of tissues, change in mitotic activity of cells, and histological characteristics was conducted, as well as quantitative stereological analysis of parenchymal cells, blood sinusoids, and connective tissues. Additionally, the protein expressions of Ki67 and CD68 markers were evaluated. Histological analysis revealed no pathological changes after the tested period. It showed the preservation of the architecture of blood sinusoids and epithelial cells and the presence of mitosis. Additionally, the significantly increased number of the Ki67 in the presence of ALBO-MPCA confirmed the proliferative effect of the material noticed by stereological analysis, while immunoreactive CD68 positive cells did not differ between groups. The study showed non-toxicity of the tested material based on the effects on the hematological, biochemical, and observed histological parameters; in addition, it showed evidence of its biocompatibility. These results could be the basis for further steps toward the application of tested materials in endodontics.

AB  - Hydroxyapatite (HA, Ca10(PO4)6(OH)2), a calcium orthophosphate, due to its similarity to the inorganic part of human’s hard tissue, is among the most frequently used hard tissue regeneration biomaterial [1]. As such, the effects of HA ageing in media similar to blood plasma need to be studied, specifically after sterilization with γ-radiation, to better understand the possible structural changes it would undergo in the human body. Moreover, such changes in ion substituted HAs are particularly interesting since so called biological HA is in fact non-stoichiometric poorly crystalline, calcium deficient, Na-, Mg- and carbonate substituted HA (Dorozhkin, 2012) [2]. In this study, HA and 3 different substituted HAs were irradiated to 25 kGy with Co-60 γ-rays and their electron paramagnetic (EPR) spectra were recorded 1, 14 and 28 days after treatment with saline solution and simulated body fluid (SBF) [3]. The ion substituted HAs were doped with Mg and Si: 2% Mg; 2% Mg + 0.4% Si and 2% Mg + 1.25% Si. EPR spectra were analysed, and the most pronounced peaks assigned. The effects of ageing in the two media are presented and discussed.

AB  - The aim of this study was to develop novel hydroxyapatite (HAP)-based bioactive bone replacement materials for segmental osteotomy reconstruction. Customized three-dimensional (3D) bone construct was manufactured from nanohydroxyapatite (nHAP) with poly(lactide-co-glycolide) (PLGA) coating using 3D models derived from the computed tomography (CT) scanning of the rabbit's ulna and gradient 3D printing of the bone substitute mimicking the anatomical shape of the natural bone defect. Engineered construct revealed adequate micro-architectural design for successful bone regeneration having a total porosity of 64% and an average pore size of 256 μm. Radiography and micro-CT analysis depicted new bone apposition through the whole length of the reconstructed ulna with a small area of non-resorbed construct in the central area of defect. Histological analysis revealed new bone formation with both endochondral and endesmal type of ossification. Immunohistochemistry analysis depicted the presence of bone formation indicators-bone morphogenetic protein (BMP), osteocalcin (OCN) and osteopontin (OPN) within newly formed bone. Manufactured personalized construct acts as a "smart" responsive biomaterial capable of modulating the functionality and potential for the personalized bone reconstruction on a clinically relevant length scale.

AB  - Thin films of titanium oxides, titanium oxynitrides and titanium nitrides were deposited on glass substrates by the methods of direct current (DC) and pulsed magnetron sputtering and cathodic arc evaporation. Phase analysis of the deposited films by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR) showed the presence of phases with various Ti oxidative states, which indicated a high concentration of oxygen vacancies. The films morphology was investigated by scanning electron microscopy (SEM). Investigations of the films wettability, either with water or ethylene glycol, showed that it depends directly on the concentration of oxygen vacancies. The wettability mechanism was particularly discussed.

AB  - Background/Aim. The deposition of hydroxyapatite (HAP) on the surface of titanium (Ti) alloys enhances bioactivity and osseointegration of the alloys which are widely used as implant materials in dentistry and orthopaedic surgery. However, the stability of HAP and subsequent biocompatibility of such alloys depends on the coating technique. The aim of this work was to test the cytotoxicity of a Ti alloy (Ti6Al4V), coated with HAP by a new plasma deposition method. Methods. The Ti6Al4V samples prepared as discs, 10 mm in diameter and 2 mm in thickness, were coated with HAP (one or both sides of the alloy) by an innovative atmospheric plasma jet method. The cytotoxicity of uncoated and HAP coated Ti6Al4V samples was evaluated by examining the morphological changes and viability of L929 fibroblasts in direct contact with the test materials. Adequate negative (polystyrene) and positive (nickel) control discs of the same size were used. The indirect cytotoxicity was determined by cultivating L929 cells with conditioning medium (CM), prepared as extract of the test samples incubated in the complete Roswell Park Memorial Institute (RPMI) 1640 medium for cell cultures. The cytotoxic effect was evaluated based on the degree of metabolic activity, necrosis, apoptosis and proliferation of L929 cells, using the appropriate assays. Results. Uncoated and one side HAP coated Ti6Al4V alloys were classified as non-cytotoxic according to the current ISO 10993-5 criteria, whereas two sides HAP coated Ti6Al4V alloy samples were slightlymoderate cytotoxic. The cytotoxicity manifested as the inhibition of metabolic activity and proliferation of L929 cells as well as the induction of their apoptosis and necrosis was significantly reduced by conditioning of HAP/Ti6Al4V alloys for 24 hours. The cytotoxic effect of HAP/Ti6Al4V CM only partly decreased in the presence of nifelate, a calcium (Ca) channel blocker, suggesting that Ca ions were not the only responsible cytotoxic agent. Conclusion. The original HAP coating procedure by atmospheric plasma spraying with high energy input enables the production of the stable adhesive coatings on Ti6Al4V alloys. Their cytotoxicity, which depends on the quantity of HAP coating layer, could be significantly reduced up to the non-cytotoxic level by prior conditioning of the alloys in culture medium. Such a procedure, which removes leachable toxic components, could be useful before implantation of HAP coated alloys in vivo. © 2019, Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.

AB  - The synthesis of a new endodontic mixture based on calcium aluminate cement is reported. Physico-chemical and mechanical properties of the mixture were investigated before and after various hydration periods. Phase analysis of the mixture was performed using X-ray diffraction (XRD), while morphological analysis was performed by scanning electron microscopy (SEM) equipped with EDS which revealed elemental composition of the mixture sample. Investigations of mechanical properties showed that this new endodontic mixture possessed good mechanical properties (compressive strength after 28 days aging was 94 MPa) and relatively short setting time (2 h). Additionally, cytotoxicity of the mixture was investigated by MTT assay, while genotoxicity was investigated by Comet assay, using MRC-5 cell line. The obtained results make this material very promising for potential application in dental practice. © 2019 Elsevier Ltd and Techna Group S.r.l.

AB  - Aim: To examine the potential systemic toxicity of nanostructured materials based on calcium silicate and calcium aluminate, for potential application in Dentistry. Methodology: Twenty-four Albino Wistar rats aged 2 months were used as an in vivo animal model for subcutaneous implantation of the investigated materials, placed in polyethylene tubes. Thirty days after implantation, the livers of the rats were analysed and following histological and stereological parameters were evaluated for volume density of hepatocytes and blood sinusoids, number and numerical density of hepatocytes, surface of hepatocytes and their nucleuses, nucleocytoplasmic ratio and mitotic index of hepatocytes. Stereological measurements were achieved using Cavalieri's principle, with grid P2 and unbiased analysis. Additionally, immunohistochemistry studies were performed to further analyse changes in liver tissue. Several haematological and biochemical parameters of blood of experimental animals were also analysed, as well as local tissue reactions around the implants. Statistical analysis was performed using parametric (anova and t-test) and nonparametric tests (Kruskal–Wallis and Mann–Whitney U-test) depending on data distribution. Results: Implanted dental cements led to an increase in stereological and histological parameters in liver tissue compared to control rats. Although the investigated parameters mostly showed significant differences between control and experimental animals, the liver tissue of the experimental animals did not have visible signs of pathological changes. This was supported by the analysis of blood parameters which were not significantly different between control and experimental animals. Also, the subcutaneous tissues had minimal inflammatory reactions. Immunohistochemistry studies revealed that nanostructured materials induced proliferation of hepatocytes, but that the immunological response to the materials was not strong enough to induce proliferation of immunoreactive cells in liver in the observed time period. Conclusions: This study was performed as a contribution to the attestation of the biocompatibility of dental cements based on calcium silicate and calcium aluminate. Although these materials induced several changes in the liver structure, they were not clinically relevant and represent a normal and reversible response of the liver to the presence of biocompatible materials in the body. Blood and immunohistochemistry analyses and local tissue reactions further confirmed that these materials possess good biocompatible potential. © 2019 International Endodontic Journal.

AB  - Dental cement materials have been developed with the aim to replace hard dental tissues. The first material used for pulp capping, root canal obturation, bifurcation perforation and apexification is calcium hydroxide (in 1920). A half century later, glass-ionomer cements began to suppress it as dentine substitutes. Finally, in the 1990s, calcium silicate (CS) material appeared in the dental research community as the most promising dentine substitute capable to adequately meet all clinical requirements. The aim of this paper is to present an overview of literature related to studies about CS materials taking into account their physical, chemical and biological properties and clinical applications. This review aims to discuss beneficial and adverse characteristics of CSs concerning interactions to the hard dentine and soft pulp/periodontal tissues. This review article deals with the literature data about currently commercially available CS concerning laboratory and clinical findings. 109 scientific articles were analyzed of which 62 references reported in vitro and 26 in vivo investigations while 21 references comprised reports, reviews and books dealing with both, in vitro and in vivo investigations. Although further data collection is necessary, CSs are promising materials that represent a gold standard for numerous dental clinical procedures. © 2019, Association of Chemists and Chemical Engineers of Serbia.

This review aims to discuss beneficial and adverse characteristics of CSs concerning interactions to the hard dentine and soft pulp/periodontal tissues. This review article deals with the literature data about currently commercially available CS concerning laboratory and clinical findings. 109 scientific articles were analyzed of which 62 references reported in vitro and 26 in vivo investigations while 21 references comprised reports, reviews and books dealing with both, in vitro and in vivo investigations. Although further data collection is necessary, CSs are promising materials that represent a gold standard for numerous dental clinical procedures. © 2019, Association of Chemists and Chemical Engineers of Serbia.

AB  - Optical properties of TixOy thin film, of thickness 125 nm, obtained by pulsed magnetron sputtering were investigated in this paper. XRD analysis revealed the presence of anatase, rutile, TiO, Ti2O3and Ti3O5phases. XPS analysis showed similar results. SEM analysis showed quite smooth surface of the film. Spectroscopic ellipsometry revealed sharp decrease of refractive index in wavelength range 300-500 nm and extremely low values of extinction coefficients which are less than 0.01 at wavelengths equal to or higher than 500 nm.
