The dental enamel, also called the adamantine substance, wraps the dentin in its fraction or third coronary, providing protection to the set of tissues or underlying structures. Composed of millions of hydroxyapatite prisms from the amino-dentin area to the incise area, it is the hardest tissue in the body.
The tooth enamel is whitish, translucent or blue-grayish in color. Usually, the teeth show a white color less in the incise third where a translucency resulting to the anisotropic crystalline organization is observed.
The characteristic color of the teeth is given by the dentin, which is the middle layer of the tooth.
- Artificial tooth enamel
Dental enamel protects the tooth from external aggressions, including acids, which can weaken it due to its high mineral composition.
Habits such as lack of dental hygiene, aggressive brushing, etc. They can cause aware of the enamel and its demineralization and also, favor cavitation of caries.
It is a poorly soluble mineral constituted by crystalline calcium phosphate. It is present in the bony and dental structures and largely forms dental enamel.
The bacteria that cause their deterioration, which are found in the oral cavity, join the dental structure forming lactic acid by synthesizing the sugars in our diet. This lactic acid with a pH of 5.5, has the power to dissolve the hydroxyapatite, deteriorating the dental structure and making it more porous and sensitive to dental caries.
Artificial tooth enamel
Japanese studies have investigated and developed, based on hydroxyapatite, the process to manufacture artificial tooth enamel. This artificial material is formed by several layers or thin sheets that look like tooth enamel. Its applications can be conservative such as correcting tooth wear or preventing the presence of cavities, and aesthetics, such as improving the color of our teeth making them look whiter.
Also the artificial tooth enamel will have a clear protective function of our teeth, being able to be placed as a coping around the tooth.
The method or practice for the hydroxyapatite to turn into dental enamel is that it is in a very fine powder and by applying heat and adding a powerful laser and salt we will obtain its crystallization.
Currently in clinic, before any problem of decalcification or abrasion of tooth enamel.
