Role of Amorphous Calcium Phosphate in Dentistry
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. This study reviews ACP structure, its properties and its applications in dentistry. Methods: In this review study, keywords including “amorphous calcium phosphate”, “mineralization”, “hydroxyapatite”, “cas...
متن کاملAmorphous calcium phosphate phase-mediated crystal nucleation kinetics and pathway.
Generally, a solution nucleation model is used to study biomineralization kinetics. However, we found that the amorphous calcium phosphate (ACP)-mediated hydroxyapatite (HAP) nucleation in simulated body fluids (SBF) had a different profile from the linear relationship between ln J and ln(-2) S (J, nucleation rate; S, supersaturation). This behaviour was alternatively explained by a developed h...
متن کاملGlycochenodeoxycholic acid inhibits calcium phosphate precipitation in vitro by preventing the transformation of amorphous calcium phosphate to calcium hydroxyapatite.
Calcium hydroxyapatite can be a significant component of black pigment gallstones. Diverse molecules that bind calcium phosphate inhibit hydroxyapatite precipitation. Because glycine-conjugated bile acids, but not their taurine counterparts, bind calcium phosphate, we studied whether glycochenodeoxycholic acid inhibits calcium hydroxyapatite formation. Glycochenodeoxycholic acid (2 mM) totally ...

متن کاملIntermediate stages of electrochemical oxidation of single-crystalline platinum revealed by in situ Raman spectroscopy
Understanding the atomistic details of how platinum surfaces are oxidized under electrochemical conditions is of importance for many electrochemical devices such as fuel cells and electrolysers. Here we use in situ shell-isolated nanoparticle-enhanced Raman spectroscopy to identify the intermediate stages of the electrochemical oxidation of Pt(111) and Pt(100) single crystals in perchloric acid...
