  • The Nano Structure of Enamel - ASME

    2021-6-28 · Enamel composition is 97 wt.% nano-hydroxyapatite and 3 wt.% organic material and water. In dentin, the nano-hydroxyapatite represents 70 wt.% 8 . As Nano-hydroxyapatite is the main component of enamel, it gives an appearance of bright white and eliminates the diffuse reflectivity of light by closing the small pores of the enamel surface.

  • Hydroxyapatite - FLUIDINOVA

    2021-6-15 · Nano-hydroxyapatite is also used as a drug carrier to deliver anti-tumour drugs . Tooth enamel has a very high hardness and wear-resistance, which depends on the braided multilayer structure and inorganic-organic composite structure . Although hydroxyapatite itself has a high promoting effect on remineralization, it is still restricted and cannot play the role of natural remineralization.
