Notes:
New biomimetic carbonate-hydroxyapatite nanocrystals (CHA) have been designed andsynthesized in order to obtain a remineralization of the altered enamel surfaces. Synthesized CHAmimic for composition, structure, nano dimension and morphology bone apatite crystals and theirchemical-physical properties resemble closely those exhibited by enamel natural apatite. CHA canchemically bound themselves on the surface of natural enamel apatite thanks to their tailoredbiomimetic characteristics. The remineralization effect induced by CHA represents a real newdeposition of carbonate-hydroxyapatite into the eroded enamel surface scratches forming apersistent biomimetic mineral coating, which covers and safeguards the enamel structure. Theexperimental results point out the possibility to use materials alternative to fluoride compoundswhich is commonly utilized to contrast the mechanical abrasions and acid attacks. The apatiticsynthetic coating is less crystalline than enamel natural apatite, but consists of a new biomimeticapatitic mineral deposition which progressively fills the surface scratches. Therefore the applicationof biomimetic CHA may be considered an innovative approach to contrast the acid and bacteriaattacks
