At the University of Ural, they made a tooth enamel stronger than natural

Researchers from Ural Federal University have developed technology to create synthetic dental emalia, which is identical to natural, but has greater strength.

In their work, researchers used hydroxyapathitis as a basic component of the bones and mineralized tissues of humans and animals, adding hydroxyapathitis to the complex of amino acids, such as lisin and arginin, which helps to regenerate bone and muscle structures, as a result of which scientists were able to create a mineralized layer with properties similar to the main component of natural emalia.

Researchers tested the finished material: for this purpose, they applied coatings to healthy teeth; then scientists tested the properties of the finished coating through chemical visualization and microscopy; it turned out that the mineralized layer had a thickness of 300 to 500 nm, and its nanocrystal structure was consistent with the structure of natural emalia.

However, researchers note that due to the high degree of uniformity, the artificial mineralized layer has increased nanostability beyond natural emalia.

Emal is a very thin but solid tooth covering, and it plays an important role in protecting against caries and other dental diseases, and it's one of the few tissues in the human body that can't regenerate, which means that the damage to the enamel is irreversible and can cause serious problems.

Researchers will continue to work on artificial coating technology to develop materials that can be applied to larger defects, such as cracks and cleavages.
