Calcium phosphate salts, or more specifically hydroxyapatite, are products of great interest in the fields of medical and dental science due to their biocompatibility and osteoconduction property. Deproteinized xenografts are primarily constituted of natural apatites, sintered or not. Variations in the industrial process may affect physicochemical properties and, therefore, the biological outco...

Organophosphorus chemistry has a crucial role in the field of drug research [1]. As generally well known, Adenosine Triphosphate (ATP) plays key energy processes all living cells mammals. There are also natural phosphorus containing organic compound, Phosphocitrate (PC), found mammalian mitochondria, likely produced by cytosolic phosphorylation citrate, and which important calcium metabolism, e...

objecttive(s): despite the poor mechanical properties of hydroxyapatite, its unique biological properties leads we think about study on improving its properties rather than completely replacing it with other biomaterials. accordingly, in this study we introduced hydroxyapatite reinforced with hardystonite as a novel bio-nanocompositeand evaluate its in-vitro bioactivity with the aim of developi...

Introduction In this study, we contemplate to prepare a new type of scaffold which mimics natural bone and consists of three different components, namely biphasic polymeric base from two different biodegradable polymers prepared by using dual porogen approach, bioactive agents, i.e., collagen and hydroxyapatite (HA) particles which distributed throughout the scaffold only on the pore surfaces. ...

Adsorption of Streptococcus mutans on hydroxyapatite and chemically treated hydroxyapatite was studied. Zeta potentials of the surfaces were measured. Chemically treated hydroxyapatite gave higher zeta potentials and lower S mutans adsorption.

Hydroxyapatite, a ceramic with which natural bone inherently bonds, has been incorporated into a polymer matrix to enhance the bioactivity of implant materials. In order to manufacture custom-made bioactive implants rapidly, selective laser sintering has been investigated to fabricate hydroxyapatite and polyamide composites and their properties investigated. One objective of this research was t...

A method of synovial fluid preparation giving optimal hydroxyapatite detection as well as definitions of the threshold masses of hydroxyapatite in viscous synovial fluid detectable by x ray diffraction and scanning electron microscopy with energy dispersive analysis is reported. Use of an equal volume of 100% hydrazine with the synovial fluid optimised detection of hydroxyapatite. By x ray diff...
