“The star of the show is nano-hydroxyapatite, which replaces fluoride and acts as a naturally occurring substance that is effective in preventing tooth decay,” she says. User review: “This ...
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 ...
For this reason, the number of toothpastes and mouthwashes that already incorporate nano-hydroxyapatite as a desensitizing agent is increasing. [14] Bioglass is a relatively new technology in toothpaste formulations. BioMin, a bioactive glass of calcium fluoro phosphosilicate, provides faster and longer lasting relief against sensitivity ...
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 ...
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).
Applying fluoride directly to the teeth through toothpaste or rinses is important, but Lochary said small amounts circulating in the body are critical for young kids who still have their baby teeth.
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 ...
The American Dental Association says adding fluoride to water streams is a "safe, beneficial, and cost-effective" public health measure, citing studies that it cuts cavities in children and adults ...
