Dental glaze-like ordered structure hydroxyapatite as well as preparation method and application thereof

The invention discloses dental glaze-like ordered structure hydroxyapatite and a preparation method and application thereof.The preparation method comprises the steps that an orthophosphate solution, a calcium salt solution, a villiaumite solution, a magnesium salt solution and an organic macromolecule solution are mixed to obtain mineralized liquid, and organic macromolecules comprise macromolecular compounds rich in carboxyl and/or sulfo functional groups; and soaking the tooth enamel subjected to acid etching treatment in a mineralizing solution, and incubating at a constant temperature. The nucleation crystallization process of calcium phosphate on the enamel crystal surface is regulated and controlled through organic macromolecules, and a layer of ordered-structure hydroxyapatite mineral with excellent mechanical properties is constructed on the enamel surface. The tooth glaze ordered structure hydroxyapatite and natural glaze crystals are of a continuous structure, have no obvious boundary, are consiste
