Supersaturation of calcium citrate as a mechanism behind enhanced availability of calcium phosphates by presence of citrate.
Garcia AC, et al. Food Res Int 2018. PMID 29580478 Free article.
This robust supersaturation, which may explain increased availability of calcium phosphates in presence of citrate, presented a degree of supersaturation of 7.1 and was characterized by precipitation rates for 0.10 mol L(-1) equimolar aqueous calcium chloride, sodium hydrogencitrate, and sodium hydrogenphosphate with pH 5.5, and for 0.10 mol L(-1) equimolar aqueous calcium chloride, sodium hydrogencitrate, and sodium dihydrogenphosphate with pH 4.1, with a degree of supersaturation of 2.7. ...Ion speciation based on measurement of pH, and total concentrations of calcium, phosphate and citrate, and of conductivity and calcium ion activity during precipitation indicates a low driving force for precipitation with calcium citrate complex dominating at pH 5.5 and calcium hydrogencitrate complex dominating at pH 4.1. ...

Calcium phosphates as fillers for methacrylate-based sealer.
Rostirolla FV, et al. Clin Oral Investig 2019. PMID 31025194
OBJECTIVES: The aim of this study was to evaluate the mineral deposition, push-out bond strength, radiopacity, the degree of conversion, film thickness, flow, calcium ion release, and pH of experimental endodontic sealers containing hydroxyapatite (HAp), aflfa-ticalcium phosphate (α-TCP), or octacalcium phosphate (OCP) particles. ...Calcium deposition values were higher for G(HAp) at 28 days. CONCLUSIONS: Bond strength, degree of conversion, and film thickness of endodontic sealers with phosphates showed similar results compared with AHplus, but displayed higher amounts of Ca(2+) release. ...

In vitro degradation of calcium phosphates: Effect of multiscale porosity, textural properties and composition.
Diez-Escudero A, et al. Acta Biomater 2017. PMID 28739544
The capacity of calcium phosphates to be replaced by bone is tightly linked to their resorbability. However, the relative importance of some textural parameters on their degradation behavior is still unclear. ...STATEMENT OF SIGNIFICANCE: The physicochemical features of calcium phosphates are crucial to tune biological events like resorption during bone remodeling. ...

Biological and medical significance of calcium phosphates.
Dorozhkin SV and Epple M. Angew Chem Int Ed Engl 2002 - Review. PMID 12207375
Similarly, dental caries and osteoporosis can be considered to be in vivo dissolution of calcium phosphates. On the other hand, because of the chemical similarity with biological calcified tissues, all calcium phosphates are remarkably biocompatible. ...For example, self-setting bone cements made of calcium phosphates are helpful in bone repair and titanium substitutes covered with a surface layer of calcium phosphates are used for hip-joint endoprostheses and tooth substitutes, to facilitate the growth of bone and thereby raise the mechanical stability. ...

Amorphous calcium phosphates: synthesis, properties and uses in biomaterials.
Combes C and Rey C. Acta Biomater 2010 - Review. PMID 20167295
This review paper on amorphous calcium phosphates (ACPs) provides an update on several aspects of these compounds which have led to many studies and some controversy since the 1970s, particularly because of the lack of irrefutable proof of the occurrence of an ACP phase in mineralised tissues of vertebrates. ...

Ionic substitutions in calcium phosphates synthesized at low temperature.
Boanini E, et al. Acta Biomater 2010 - Review. PMID 20040384
This review provides an overview of the recent results achieved on ion-substituted calcium phosphates prepared at low temperature, i.e. by direct synthesis in aqueous medium or through hydrolysis of more soluble calcium phosphates. Particular attention is focused on several ions, including Si, Sr, Mg, Zn and Mn, which are attracting increasing interest for their possible biological role, and on the recent trends and developments in the applications of ion-substituted calcium phosphates in the biomedical field....

Calcium Phosphate System for Gene Delivery: Historical Background and Emerging Opportunities.
Mostaghaci B, et al. Curr Pharm Des 2016 - Review. PMID 26654437
However, there was a major drawback regarding the low transfection efficiency of calcium phosphate. Hence, there have been many efforts in order to increase the gene delivery potential of this system. In this paper, the application of calcium phosphate in gene delivery is introduced. Moreover, the recent progresses in the application of calcium phosphate in the delivery of (oligo)nucleotides and different approaches to improve the properties of this system are reviewed....

Formation of calcium phosphates in gelatin with a novel diffusion system.
Teng S, et al. Colloids Surf B Biointerfaces 2006. PMID 16621478
The present paper demonstrated a novel and simple diffusion system to precipitate calcium phosphates in gelatin gel. In this system, a gelatin cup was specially used as the membrane separating reservoirs of calcium and phosphate ions. ...The novel diffusion system is proposed to play an important role in both studying the process of biological mineralization and synthesizing calcium phosphates in different forms....
