The proposed mechanism of action of topical fluoride is the formation of intraoral calcium fluoride reservoirs, which are retained on enamel and slowly released to inhibit mineral loss during demineralization. However, the formation of the intraoral calcium fluoride reservoirs is limited by the availability of intraoral calcium and fluoride ions.

Fluoride has been shown to be present in the pineal glands of older people (14-875 mg of fluoride per kg of gland in persons aged 72-100 years), with the fluoride concentrations being positively related to the calcium concentrations in the pineal gland, but not to the bone fluoride, suggesting that pineal fluoride is not necessarily a function ...
Abstract. Lithium fluoride is an important candidate material for windows on high-power, short-pulse ultraviolet and visible lasers. Lithium fluoride crystals have been press forged in one step over the temperature range 300 to 600/sup 0/c to obtain fine-grained polycrystalline material with improved mechanical properties.

Feb 01, 2016 The calcium fluoride that is deposited onto a tooth surface after fluoride therapy is not readily soluble and can act as a fluoride reservoir . This fluoride also can lower the critical pH value of hydroxyapatite crystal dissolution, or the pH value when demineralisation occurs, from approximately 5.5 to 4.5 in the mouth.

The Importance of Cell Salts Cell salts stimulate the body’s natural healing mechanisms to satisy mineral imbalances. In his biochemic theory, Dr. Schuessler, the discoverer of cell salts, states that deficiencies in these minerals are the source of common health problems and the cell salts derived from these minerals give the body what it needs to treat illness and be well.

Whereas, tri-calcium phosphate (TCP) formula through a manufacturing process of mechanochemical ball milling of tri-calcium phosphate with fumeric acid will form a barrier that inhibits the calcium from attaching to the fluoride ions. The barrier eventually will break down on the tooth surface and allow the calcium to be readily available. (6)
Dec 13, 2019 Fluoride is a naturally occurring element, which can seep out of bedrock into groundwater. Also found in volcanic ash, fluoride is particularly abundant in regions surrounding volcanoes. We want it to be an easy, practical solution for people who have the greatest need.
Background. The aim of study was to evaluate the application of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride regarding their effect on the shear bond strength (SBS), bond failure pattern of brackets using the adhesive remnant index (ARI) and assessing the quality of enamel surface using the enamel damage index (EDI).
Ammonium bifluoride is an inorganic, fluoride-containing compound found in glass and metal etching products, as well as wheel cleaners. Fluoride toxicity is a common cause of preventable poisoning and has been reported to cause life-threatening ventricular dysrhythmias. Here, we report a case of recurrent ventricular fibrillation secondary to ingestion of ammonium bifluoride.
