The Reaction of Monofluorophosphate with Apatite
Caries Research, 2009The action of sodium monofluorophosphate on Syntheti chydroxyapatites has been studied using pure mono- syntheticfluorophosphate solutions.Monofluorophosphate-treated hydroxyapatite was less soluble in acid buffer than fluoride-treated mineral of similar fluorine content. During the reaction some orthophosphate was liberated from the solid and addition

[Fluoride ions and apatite recrystallization of apatite in enamel].
Prakticke zubni lekarstvi, 1991The authors discuss the basic process on which the principle of fluoridation in based--i.e. the mutual exchange of F- ions and the OH- group in hydroxyapatite of enamel. Model investigations assessing the energy difference between hydroxyapatite and F- and fluorapatite and the OH- group indicate that fluorapatite tends to release steadily fluoride ions

Hydrothermal preparation of fibrous apatite and apatite sheet
Solid State Ionics, 2002Abstract Hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 :HA) with highly designed microstructures is required for bone filling materials and tissue engineering of cultured bones. This study deals with the shape control of HA particles and preparation of HA sheet from fibrous HA.
