However, during the defluoridation process the hydroxyapatite dissolves, and increases the pH and phosphate ion concentration which makes the defluoridated water unfit for drinking. [46] Recently, a ″calcium amended-hydroxyapatite″ defluoridation technique was suggested to overcome the phosphate leaching from hydroxyapatite. [ 46 ]
The addition of fluoride to the water does not alter the taste or smell of the drinking water [citation needed] Fluoride therapy is often used to promote remineralization. This produces the stronger and more acid-resistant fluorapatite, rather than the natural hydroxyapatite. Both materials are made of calcium.
Amorphous calcium phosphate in combination with casein phosphopeptide has been used as a dental treatment to treat incipient dental decay. ACP sees its main use as an occluding agent, which aids in reducing sensitivity. Studies have shown that it does form a remineralized phase of hydroxyapatite consistent with the natural enamel.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Water is really good for you, no one is arguing that. But are certain waters better for you than others? Depends on who you ask. While plenty of people are content to drink plain old H2O, there ...
Boxabl’s Baby Box is a 120-square-foot foldable home that can be set up in 60 minutes and has off-grid features. Kurt “CyberGuy" Knutsson says it's designed to maximize functionality.
Water fluoridation is the controlled addition of fluoride to public water supplies to reduce tooth decay. Fluoridated water maintains fluoride levels effective for cavity prevention, achieved naturally or through supplementation. [2] In the mouth, fluoride slows tooth enamel demineralization and enhances remineralization in early-stage cavities ...
THMs have been detected at 38.1 ppb in NYC’s water supply, according to EWG data from 2013-19. The US limits THM in drinking water to 80 ppb, while the EWG recommends not exceeding 0.15 ppb .
