   In various studies the use of nano hydroxyapatite in toothpaste showed positive results in aiding the remineralisation of dental enamel. [32] In addition to remineralisation, in vitro studies have shown that toothpastes containing nano-hydroxyapatite have the potential to reduce biofilm formation on both tooth enamel and resin-based composite ...

   In 1980, the Japanese company, Sangi Co., Ltd., launched APADENT, the world's first remineralizing toothpaste to use a nano-form of hydroxyapatite, the main component of tooth enamel, rather than fluoride, to remineralize areas of mineral loss below the surface of tooth enamel (incipient caries lesions).

5. Remineralisation of teeth - Wikipedia

   en.wikipedia.org/wiki/Remineralisation_of_teeth

   When fluoride ions are present in plaque fluid along with dissolved hydroxyapatite, and the pH is higher than 4.5, [16] a fluorapatite-like remineralised veneer is formed over the remaining surface of the enamel; this veneer is much more acid-resistant than the original hydroxyapatite, and is formed more quickly than ordinary remineralised ...

6. Topical fluoride - Wikipedia

   en.wikipedia.org/wiki/Topical_fluoride

   Fluoride has a high tendency to react with the calcium hydroxyapatite Ca10(PO4)6(OH)2 in tooth enamel due to its high affinity to metals. [8] [10] It subsequently replaces the hydroxide group in hydroxyapatite to precipitate calcium fluorapatite Ca5(PO4)3)F. [8] These fluorapatite precipitations scavenge excess phosphate and calcium in the saliva to form a supersaturated solution for ...

   Toothpaste (dentifrice) with fluoride, or alternatives such as nano-hydroxyapatite, is an important tool to readily use when tooth brushing. The fluoride (or alternative) in the dentifrice is an important protective factor against caries, and an important supplement needed to remineralize already affected enamel. [38]
