The present study aimed to document Candida albicans biofilm development on titanium and its modulation by a peroxidase-precoated material which can generate antimicrobials, such as hypoiodite or hypothiocyanite, from hydrogen peroxide, iodide, or thiocyanate. For this purpose, titanium (powder or foil) was suspended in Sabouraud liquid medium inoculated with C. albicans ATCC10231. After contin...

BACKGROUND AND PURPOSE To elaborate a method for applicator reconstruction for MRI-based brachytherapy for cervical cancer. MATERIALS AND METHODS Custom-made plastic catheters with a copper sulphate solution were made for insertion in the source channels of MR-CT compatible applicators: plastic and titanium tandem ring applicators, and titanium needles. The applicators were CT and MR scanned ...

OBJECTIVES 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). Control a...

PURPOSE Polycarbonate peg has been customarily used for pegging of hydroxyapatite for years. For better movement, tissue tolerance, and to decrease the complications of pegging, titanium peg system has been used. This study compares the two systems. METHODS Complications associated with pegging (polycarbonate: Bio-Eye or titanium: Dr-Perry new P-K) were retrospectively reviewed from the chart...

The 5-year results from a multicenter study of implant-supported, laser-welded titanium frameworks are reported here as a complement to earlier reported 2-year results. Implant survival rates were satisfactory for patients with titanium frameworks and for a control group of patients with gold-alloy frameworks. At the 5-year review, more patients with titanium frameworks had lost implants than t...

A new strategy with bone tissue engineering by mesenchymal stem cell transplantation on titanium implant has been dawn attention. The surface scaffold properties of titanium surface play an important role in bone regenerative potential of cells. The surface topography and chemistry are postulated to be two major factors increasing the scaffold properties of titanium implants. This study aimed t...

NaCl­KCl­TiClx was prepared via using titanium sponge to reduce titanium tetrachloride in a NaCl­KCl melt under a negative pressure at 1023K. The relationship between titanium valence states and [F]/[Ti] molar ratios was investigated with successive adding potassium fluoride in the pre-prepared NaCl­KCl­TiClx. It was found that the average valence of titanium ions tended to be stable around 3.0...

Surface modification of titanium for use in orthopedics has been explored for years; however, an ideal method of integrating titanium with native bone is still required to this day. Since human bone cells directly interact with nanostructured extracellular matrices, one of the most promising methods of improving titanium's osseointegration involves inducing bio-mimetic nanotopography to enhance...

INTRODUCTION: Titanium and titanium alloys have attracted considerable interest in aerospace, chemical process and biomedical industry due to their biocompatibility, good mechanical properties and excellent corrosion resistance. The chemical stability of titanium results from the presence of a thin but stable surface oxide film, typically a few nanometer thick. In nonaqueous electrolytes contai...
