What is Hydroxyapatite?

Hydroxyapatite is a naturally occurring mineral form of calcium apatite. It is the main component of tooth enamel and bone in vertebrates. Hydroxyapatite crystals provide strength and rigidity to these biological structures. In terms of chemical composition, hydroxyapatite is a calcium phosphate compound with the formula Ca₅(PO₄)₃(OH).

Apart from its presence in teeth and bones, hydroxyapatite is also used in various medical and dental applications. It is commonly employed in the production of dental implants and bone grafts due to its biocompatibility and ability to integrate with natural bone tissue. Additionally, hydroxyapatite is used in some biomaterials and coatings for medical devices.

In the field of materials science, hydroxyapatite is studied for its unique properties, and researchers explore its potential applications in areas such as drug delivery, tissue engineering, and the development of bioactive materials.
