At Horst 89 IS, fluorapatite occurs as massive green aggregates with pink barite
crystals and monazite and at Bandelierskop, green crystals are found with yellow

Textbook of Preventive and Community Dentistry
If the tooth at this stage is exposed to fluoride, these hydroxyapatite crystals will
get converted into fluorapatite, which are least soluble (Fig. 35.6). It has been
shown that small amount of fluoride in an acid solution can have pronounced
effect ...

Wastewater containing boron should not be mixed with wastewater containing
fluorine. By adding lime to a wastewater containing both phosphate and fluorine,
fluorapatite Ca^PO^F is precipitated, which is much less soluble than CaF2.

associated with conversion of hydroxyapatite to fluorapatite. However, with the
high concentrations of fluoride used in topical treatments, calcium fluoride is
formed in addition to fluorapatite (McCann and Bullock, I955; Leach, 1959).
