What is hydroxyapatite? How is hydroxyapatite different from other active substances? What is apatite?
甚麼是 hydroxyapatite? Hydroxyapatite 與其他活性物質有甚麼分別？甚麼是 apatite？
Apatite and hydroxyapatite are both minerals and belong to the calcium phosphate family. There are a number of different calcium phosphates. Hydroxyapatite is the most stable and the most important calcium phosphate for humans, as it forms the mineral phase of bones and teeth. The chemical formula of hydroxyapatite is: Ca5(PO4)3(OH).
Hydroxyapatite plays an essential role in the human body. It forms the basis for teeth and bones. In both cases, hydroxyapatite is responsible for their hardness. Unlike many other active ingredients used in dental care, hydroxyapatite occurs naturally in the human body.
Apatite 和 hydroxyapatite 都是屬於磷酸鈣家族的礦物質。磷酸鈣有很多種，其中由於 hydroxyapatite 形成了骨骼和牙齒的礦物相，因此是一種最穩定和對人類最重要的磷酸鈣。Hydroxyapatite 的化學式為：Ca5(PO4)3(OH)。
Hydroxyapatite 對人體十分重要，是構成牙齒和骨骼的基礎物質，亦是令牙齒和骨骼堅硬的成份。與牙科護理中所使用的眾多其他活性成份不同，hydroxyapatite 天然存在於人體中。
