Polymers, being one of the most important materials in dentistry, offer great physical and mechanical qualities, as well good biocompatibility. Aim this study was done to evaluate Polyetherketoneketone polymer composite material used dental implant through evaluation including (flexural strength, Wettability). composites (Polyetherketoneketone titanium oxide nanoparticles with selected weight p...

titanium salts are widely used in pharmacy and industry as intensely white permanent pigment with good covering power in paints , paper , toothpaste , plastics and food dye s. this ion is a redox-active transition metal and may cause oxidative damages to lipids, proteins and dna molecules. in spite of abundant literature, questions about the side effects of titanium ions still remain to be answ...

a modified electrode was prepared by modification of the carbon paste electrode (cpe) with graphene nano-sheets. the fabricated modified electrode exhibited an electrocatalytic activity toward gallic acid (ga) oxidation because of good conductivity, low electron transfer resistance and catalytic effect. the graphene modified cpe had a lower overvoltage and enhanced electrical current respect to...

Although fluoride induces corrosion in titanium in an oral environment, the influence of protein on this corrosion remains to be clarified. The objective of this study was to investigate suppression of fluoride-induced corrosion of titanium where albumin was either present in a solution or where albumin was preadsorbed on titanium. Titanium dissolution in titanium specimens and surface characte...

There are very few reports on hypersensitivity reactions in association with titanium-based materials so that the existence of allergy to titanium is still put in question. We report on a patient in whom impaired fracture healing and eczema localized to the perioperative area developed upon titanium-based osteosynthesis. Patch testing gave no reactions to titanium nor to nickel, chromium, or co...

Titanium (Ti) mesh plates are used as a bone replacement in brain tumor surgeries. In the case of radiotherapy, these plates might interfere with the beam path. The purpose of this study is to evaluate the effect of titanium mesh on the dose distribution of electron fields. Simulations were performed using Monte Carlo BEAMnrc and DOSXYZnrc codes for 6 and 10 MeV electron beams. In Monte Carlo s...
