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...

PURPOSE To compare the shear bond strength of various veneering materials to grade II commercially pure titanium (CP-Ti). MATERIALS AND METHODS Thirty specimens of CP-Ti disc with 9 mm diameter and 10 mm height were divided into three experimental groups. Each group was bonded to heat-polymerized acrylic resin (Lucitone 199), porcelain (Triceram), and indirect composite (Sinfony) with 7 mm di...

The study was conducted to determine the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of AA in egg from hens hyperimmunized with Escherichia coli K88 antigens (EGG) fed to weaned pigs. Spray dried porcine plasma (SDPP) was included for comparison. Eight barrows (Yorkshire-Landrace × Duroc; initial BW of 17 ± 1 kg) were fitted with a T-cannula at the distal ileum...

OBJECTIVE Orthodontically induced inflammatory root resorption (OIIRR) is an undesirable sequel of tooth movement after sterile necrosis that takes place in periodontal ligament due to blockage of blood vessels following exertion of orthodontic force. This study sought to assess the effect of an angiogenic cytokine on OIIRR in rat model. MATERIALS AND METHODS In this experimental animal study...

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...

Titanium particles generated from orthopedic and dental implants are suspected to play an important role in peri-implant osteolysis. Elucidation of the mechanisms involved in the effects of titanium particles on osteolysis may provide methods for preventing osteolysis. Therefore, in the present study, we investigated the effect of titanium particles on osteoclast activity in vitro. We evaluated...
