(hī-drok'sē-ap'ă-tīt),

hydroxyapatite

, hydroxylapatite (hī-drok″sē-ap′ă-tīt″) (″sĭ-lap′ă-tīt″) [ hydro- + ²oxy- + apatite ]
Ca10(PO4)6(OH)2; the calcium- and phosphorus-containing compound that constitutes the bulk of the mineral structure of bones and teeth. In teeth it is soluble in the acids of soft drinks or carbohydrate fermentation, but it becomes decay-resistant fluoroapatite after combining with fluoride ions present in fluoridated water or fluoride toothpastes. Under some circumstances, it can deposit in and around joints, producing periarthritis or calcific tendinitis.
