Thermally processed hydroxyapatite coatings used on dental implants and hip prostheses for enhanced fixation may typically consist of a number of chemical and structural phases. These phases affect coating performance and tissue attachment. Hydroxyapatite was plasma sprayed to examine the phase evolution during processing. Coatings were examined with X-ray diffraction and elemental analysis. Re...

Comparative Study on Remineralizing Ability of Casein Phosphopeptide Amorphous Calcium Phosphate and β-Tricalcium Phosphate on ...
In humans and other mammals it is known that calcium and phosphate ions are secreted from the distal small intestine into the lumen. However, why this secretion occurs is unclear. Here, we show that the process leads to the formation of amorphous magnesium-substituted calcium phosphate nanoparticles that trap soluble macromolecules, such as bacterial peptidoglycan and orally fed protein antigen...
Calcium phosphate chitosan-based composites have gained much interest in recent years for biomedical purposes. In this paper, three-dimensional calcium phosphate chitosan-based composites with different mineral contents were produced using a green method called ice segregation induced self-assembly (ISISA). In this methodology, ice crystals were used as a template to produce porous structures f...
Mineral trioxide aggregate (MTA) was developed in early 1990s and has been successfully used for root perforation repair, root end filling, and one-visit apexification. MTA is composed mainly of tricalcium silicate and dicalcium silicate. When MTA is hydrated, calcium silicate hydrate (CSH) and calcium hydroxide is formed. Formed calcium hydroxide interacts with the phosphate ion in body fluid ...
A 59-year-old Chinese patient had a history of endstage renal disease secondary to glomerulonephritis and underwent peritoneal dialysis. Nine years after initiation of dialysis, he developed an enlarging ‘tumour’ over his right wrist in the absence of antecedent trauma. Within 1 month of presentation, he was unable to use chopsticks because of the painful mass. At that time, his serum calcium a...
Glasses in the system 24.5Na2O.24.5CaO.6P2O5.xSrO.(45-x)SiO2 have been studied composition region of x = 0–15 mol%. The as-prepared glasses are transparent and an amorphous network structure. On other hand, heat-treated transformed to opaque white glass-ceramic characterized by their highly crystalline Crystalline apatite (calcium phosphate, Ca3(PO4)2), wollastonite silicate, CaSiO3), strontium...
The aim of this in vitro was to evaluate the effects of tricalcium phosphate (TCP) and amorphous calcium phosphate (ACP) containing varnish materials and Er:YAG laser irradiation on enamel demineralization around orthodontic brackets. Forty extracted human premolar teeth were randomly divided into four treatment groups (i.e., 10 in each group): (1) 5% NaF-ACP varnish, (2) 5% NaF-TCP varnish, (3...
ACP (amorphous calcium phosphate) and DCPD (dicalcium phosphate dihydrate, or Brushite) powders were high energy dry ball milled at a 1:1 ratio for 1, 2, 3, 4, 10, or 24 hours to produce a variety of powders for use as calcium phosphate cements (CPC). A 1:1 blend of powders not subjected to milling was used as baseline material (control). Physicochemical and mechanical characterization was perf...
PURPOSE Enamel erosion can occur with frequent consumption of sports drinks. The purpose of this study was to determine a minimal concentration of casein phosphopeptide-stabilized amorphous calcium phosphate (CPP-ACP) which when added to a sports drink would eliminate such erosion in vitro. METHODS Human enamel specimens were immersed in: (1) the sports drink Powerade; (2) Poweradeplus 4 conc...
