A New Discovery Can Help Restore Teeth Enamel

Tooth enamel can be restored by adding a complex of amino acids to the mineralized material hydroxyapatite, discovered through joint research by scientists at Ural Federal University, Voronezh State University, Voronezh State Medical University, Al-Azhar University, and the National Research Center (Egypt).

What to know:

  • Tooth enamel has a protective function, but its integrity can be destroyed by abrasion, erosion, or microfractures to a point that if the surface of the tissue is not repaired in time, the enamel lesion will affect the dentin and then the pulp of the tooth.

  • Current tooth restorative techniques involve acid etching of the enamel to increase the bonding effect, which sometimes leaves behind products which may not always have a positive effect on the bonding of enamel and synthetic materials.

  • Hydroxyapatite is a compound that is a major component of human bones and teeth and mixing it with polyfunctional organic and polar amino acids can create a dental coating that replicates the composition and microstructure of natural tooth enamel.

  • The new method of dental restoration can be used to reduce the sensitivity of teeth in case of enamel abrasion or to restore it after erosion.

  • The new composition material duplicates the features of the surface of the tooth at the molecular and structural level and actually exceeds the strength of the native enamel.
