Effect of nano-hydroxyapatite on remineralization of enamel
Hydroxyapatite is the main building block of vertebrate bones and teeth, and 97% of human tooth enamel is hydroxyapatite. Initially, hydroxyapatite was used by NASA to restore minerals for astronauts' teeth and bones in weightlessness. Nano-hydroxyapatite (nano-HA) is a material with multiple uses that is biocompatible and resembles inorganic bone [...]
