Role of Amorphous Calcium Phosphate in Dentistry

open access: yesJournal of Dental School, 2019
Objective: Amorphous calcium phosphate (ACP) is a reactive solution capable of releasing calcium and phosphate ions, conversion to apatite and remineralization of mineral tooth structure.

Amorphous Calcium Phosphate and Amorphous Calcium Phosphate Carboxylate: Synthesis and Characterization. [PDF]

open access: yesACS Omega, 2023
Amorphous calcium phosphate (ACP) is the first solid phase precipitated from a supersaturated calcium phosphate solution. Naturally, ACP is formed during the initial stages of biomineralization and stabilized by an organic compound. Carboxylic groups containing organic compounds are known to regulate the nucleation and crystallization of hydroxyapatite.

In-situ Raman spectroscopy of amorphous calcium phosphate to crystalline hydroxyapatite transformation [PDF]

open access: yesMethodsX, 2018
Amorphous calcium phosphate (Ca3(PO4)2xnH2O; n = 3–4.5; ACP) is a precursor phase of the mineral hydroxyapatite (Ca5(PO4)3(OH); HAP) that in natural settings occurs during both authigenic and biogenic mineral formation.

Amorphous 1-D nanowires of calcium phosphate/pyrophosphate: a demonstration of orientated growth of amorphous minerals [PDF]

open access: yes, 2023
Amorphous inorganic solids are traditionally isotropic, thus, it is believed that they only grow into morphologies of nanospheres or irregular aggregates of nanoparticles.

Transient amorphous calcium phosphate in forming enamel [PDF]

open access: yesJournal of Structural Biology, 2009
Enamel, the hardest tissue in the body, begins as a three-dimensional network of nanometer size mineral particles, suspended in a protein gel. This mineral network serves as a template for mature enamel formation. To further understand the mechanisms of enamel formation we characterized the forming enamel mineral at an early secretory stage using X-ray

A thermochemical approach for calcium phosphate precipitation modeling in a pellet reactor [PDF]

open access: yes, 2003
A common pathway for P-recovery from wastewater is phosphate precipitation as calcium phosphates. In this paper, a thermodynamic model for phosphate precipitation is proposed based on various models of activity coefficients taking into account various ...
