Introduction
Hydroxyapatite (HAP) is the main inorganic component of human and animal bones. It can achieve chemical bonding with the body tissue at the interface, it has a certain solubility in the body, can release ions that are harmless to the body, can participate in metabolism in the body, stimulate or induce bone hyperplasia, and can promote the regeneration of defective tissues. Repaired, showing biological activity.
Hydroxyapatite, also known as hydroxyapatite, basic calcium phosphate, is a natural mineralization of calcium apatite (Ca5(PO4)3(OH)). But it is often written as (Ca10(PO4)6(OH)2) to highlight that it is composed of two parts: hydroxyl and apatite. OH- groups can be replaced by fluoride, chloride and carbonate ions to form fluorapatite or chloroapatite, in which calcium ions can be replaced by various metal ions through ion exchange reactions to form corresponding metal ions The M apatite (M stands for the metal ion that replaces the calcium ion). Hydroxyapatite (HAP) is the main inorganic component of vertebrate bones and teeth. The content of Hydroxyapatite in human tooth enamel is about 96Wt.% (92Vol.%), and it also accounts for about 69Wt.% in bones. Hydroxyapatite has excellent biocompatibility and bioactivity, and can be used as a bone or tooth inducer, and has good remineralization, desensitization and whitening effects on teeth in the field of oral health care. Experiments have shown that HAP particles have good biocompatibility and high affinity with tooth enamel, and its mineralization solution can effectively form remineralization deposits, prevent calcium ion loss, solve the problem of tooth enamel demineralization, and fundamentally prevent dental caries. Toothpaste containing HAP material has a strong adsorption effect on salivary protein and glucan, which can reduce the dental plaque in the patient's mouth, promote the healing of gingivitis, and have a good preventive effect on caries and periodontal disease.

Applications
Bone replacement Materials, Plastic and Cosmetic Surgery, Dentistry, Chromatographic Purification, Calcium Supplements, are widely used in the manufacture of cutting-edge new materials that identify tooth or bone components. In addition, due to the osteoinductive properties of Hydroxyapatite, it is often used in bone tissue regeneration engineering.
