    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.
