flu·or·ap·a·tite

 (flo͞o′ôr-ăp′ə-tīt′, -ər-)
n.
A hard, variously colored apatite mineral, calcium fluoride phosphate, Ca5F(PO4)3, that is the most common phosphate mineral and is used in the manufacture of fertilizers. Fluorapatite is formed in tooth enamel exposed to fluoride and helps prevent decay by its resistance to acidity. Also called apatite.

These fluoride ions become incorporated into the mineral forming fluoroapatite resulting in a significant reduction to further dissolution of enamel surface.
Lussi et al.12 has reported that any pH below 4.5 is critical.12 They also have reported that any pH above 4.5 will cause precipitation of fluoroapatite and hence DE becomes less likely.
The main examples include nanoparticles of tricalcium phosphate (TCP) and fluoroapatite, which have been introduced in electrospun nanofibers of PLA [224-226], PCL [227], PLGA [228], PVP [229], and PHB [230].
