A mechanism for incorporation of carbonate into apatite

N. S. Chickerur, +2 more
- 01 Jan 1980 - 
TL;DR: A structural mechanism for the incorporation of impurities during hydrolysis of octacalcium phosphate is presented, of particular importance since the presence of carbonate in human enamel appears to be related to caries susceptibility.

Thermodynamic Solubility Product of Human Tooth Enamel: Powdered Sample

P.R. Patel, +1 more
- 01 Jul 1975 - 
TL;DR: Solubility of human dental enamel in H3PO4 was studied in the pH range of 4.5 to 7.6 and the ion activity product, (Ca2+)5(PO4 3-)3 (OH-), for hydroxyapatite varied depending on the cumulative amount of the dissolution in a series of repetitive sequences of solubility experiments.

An intermediate state in hydrolysis of amorphous calcium phosphate.

M. S. Tung, +1 more
- 01 Sep 1983 - 
TL;DR: The thermodynamic analysis of the solution composition data suggests that ACP converts into a nonstoichiometric apatite when the OCP-like intermediary is formed, and a stoichiometric Apatite is formed when no O CP- like intermediary is involved.

Octacalcium Phosphate Solubility Product from 4 to 37-Degree-C

M. S. Tung, +3 more
- 01 Sep 1988 - 
TL;DR: Etude de la solubilite de l'OCP, important intermediaire dans la formation des dents et des os as mentioned in this paper, influence d'une atmosphere riche en CO 2

Effect of carbonate content on the ESR spectrum near g = 2 of carbonated calciumapatites synthesized from aqueous media.

Freddy Callens, +4 more
- 01 Feb 1989 - 
TL;DR: The ESR spectrum of X-irradiated carbonated apatites synthesized at low temperature was studied as a function of their carbonate content and it is argued that this surface signal may still be composite and caused by several very similar CO2− ions.
