Definitions
- the present invention relates to a monofluorophosphate-containing oral composition.
- Tooth enamel is mainly composed of hydroxyapatite, and usually, in the mouth, phosphate ions and calcium ions are eluted (demineralized) and crystallized into calcium phosphate-dinodoxyapatite (re-lime). Is in equilibrium. Fluoride ions suppress demineralization in an acidic environment, and in a neutral environment, promote the crystallization of calcium ions and phosphate ions, that is, remineralization, thereby preventing caries.
