L'hydroxyapatite cristallise dans le système … WebApatite is a mineral found in tooth enamel. When fluoride toothpastes are used, the mineral is converted to fluoroapatite, which is much harder and therefore more resistant to tooth decay. The formula for fluoroapatite is Ca 5 (PO 4) 3 F (molar mass = 504.5 g/mol).
