Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and function within tooth structure.
Tooth decay is caused by bacteria naturally present in one's mouth. These bacteria form a sticky, colorless soft film on the teeth called plaque. When foods containing carbohydrates (starches and sugars) are eaten, the bacteria that form plaque use the sugar as a form of energy. They also turn it into a glue-like substance that helps them stick ...
Acidulated phosphate fluoride (APF) gel or foam comprises a sodium fluoride solution, paste, or powder that has been acidulated with hydrofluoric acid to pH 3 to 4, buffered with a phosphate, and mixed with a gel or foam vehicle such as carboxymethyl cellulose. 1.23% acidulated phosphate fluoride gel or foam is used for patients without tooth ...
Along with hydroxylapatite, it can be a component of tooth enamel, especially in individuals who use fluoridated toothpaste, but for industrial use both minerals are mined in the form of phosphate rock, whose usual mineral composition is primarily fluorapatite but often with significant amounts of the other.
The perception of tooth colour is multi-factorial. Reflection and absorption of light by the tooth can be influenced by a number of factors including specular transmission of light through the tooth; specular reflection at the surface; diffuse light reflection at the surface; absorption and scattering of light within the dental tissues; enamel mineral content; enamel thickness; dentine colour ...
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
In recent years, hydroxyapatite nanocrystals (nHA) have been used in toothpaste to combat dental hypersensitivity. They aid in the repair and remineralisation of the enamel, thus helping to prevent tooth sensitivity. Tooth enamel can become demineralised due to various factors, including acidic erosion and dental caries.
