| Abstract: | Dental hard tissues lack the ability to self?heal.In dentin and cementum,hydroxyapatite(HA)can exist outside and/or inside collagen fibers.It is difficult to repair or regenerate HA with a highly ordered orientation in the presence of collagen fibers.At present,the biomimetic mineralization of dentin and cementum,mainly carried out by im?itating its biological formation process and its physiological structure,can be divided into those originating from the fi?ber mineralization mechanism and those with HA as the main component.The materials used include natural materials such as demineralized dentin matrix(DDM)and calcined bovine hydroxyapatite(BHA),and synthetic materials such as polymer?induced liquid precursor(PILP)and synthetic HA.In the future,natural materials and synthetic materials should be combined for the restoration and regeneration of dentin and cementum by means of biomimetic mineralization of calcium phosphate released by remineralization solution?HA. |
