PURPOSE The aim of this study was to compare osteoblast behavior on zirconia and titanium under conditions cultured with bone morphogenetic protein-2. METHODS MC3T3-E1 cells were cultured on sandblasted zirconia and sandblasted/etched titanium discs. At 24 hours after seeding MC3T3-E1, the demineralized bone matrix (DBM) gel alone and the DBM gel with bone morphogenetic protein-2 (BMP-2) were...

Anodically oxidized titanium surfaces, prepared by spark discharge, have micro-submicron surface topography and nano-scale surface chemistry, such as hydrophilic functional groups or hydroxyl radicals in parallel. The complexity of the surface characteristics makes it difficult to draw a clear conclusion as to which surface characteristic, of anodically oxidized titanium, is critical in each bi...

82 LLE Review, Volume 70 In recently published work we discussed the signatures of mixing1 and of target performance2 provided by incorporating a titanium-doped layer within the shell of imploding targets. We report here on the results of an experiment on OMEGA using such targets. We observe the predicted absorption features formed by the titanium layer: absorption lines due to 1s–2p transition...

The attachment of cells to titanium surfaces is an important phenomenon in the area of clinical implant dentistry. A major consideration in designing implants has been to produce surfaces that promote desirable responses in the cells and tissues. To achieve these requirements, the titanium implant surface can be modified in various ways. This research was designed to elucidate the relationship ...

The consequences of zinc oxide (ZnO), Aluminum oxide ( 3 2O Al ) and Titanium oxide (TiO2) on tree growth have been comprehensively investigated in this paper. Zinc oxide (ZnO), II-VI compound semiconductor, is used in varistors in power insulation life. Due to its excellent electrical properties such as nonlinearity of current-voltage (I-V) characteristics, high fast-transient response and hig...

Introduction Titanium and its alloys have excellent mechanical properties and biocompatibility. In the field of dentistry, smooth surfaced titanium implants inserted into the facial bones perform very well. After implantation, well-fixed dental implants, which are not subjected to weight loading during some period after implantation, exhibit direct contact with bone without intervening fibrous ...

Objective(s):Anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. We have investigated the adhesion and proliferation properties of H9C2 cardiac myoblasts on anodized treated titanium surface.  Materials and Methods: Surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (SEM). Contro...

introduction: the aim of this study was to assess the caries-preventive potential of carbon dioxide (co2) laser application in conjunction with the use of titanium tetra fluoride solution on the enamel adjacent to bracket. methods: seventy-five freshly extracted bovine incisors were used. in order to attach the brackets, the area of examination was covered with adhesive tape to limit acid etchi...

the potential to cause tissue damage by metal ions is the matter of widespread investigation. titanium salts are widely used in industry for ceramic painting, in pharmacy for tablet coating and making chemical sunscreens and in medicine as photo catalysts with bactericidal activity. this may address the idea that the exposure to these salts could play a role in metabolic disorders. in this stud...
