Dental enamel is the hard, mineralized outer layer of teeth. It is the biological substrate that the source archive dental-enamel dossier seeks to restore.
Structure and properties
The Nature Communications abstract quoted in the dossier describes enamel as "characterised by an intricate hierarchical organization of apatite nanocrystals that bestows high stiffness, hardness, and fracture toughness." The hierarchy runs from nanoscale apatite crystals up through larger organized structures, and it varies between anatomical regions of the enamel layer — a point the paper's claim explicitly addresses when it says the treatment recreates "the microarchitecture of the different anatomical regions of enamel."
Non-regeneration
The same abstract states that "enamel does not possess the ability to regenerate, and achieving the artificial restoration of its microstructure and mechanical properties in clinical settings has proven challenging." Enamel is formed during tooth development and is not renewed afterward, which is why restorative dentistry replaces lost enamel with synthetic materials rather than regrowing it.
Clinical targets named in the dossier
- Enamel erosion — loss of enamel mineral, named in the paper's abstract as a target for the claimed mineralising technology.
- Dental hypersensitivity — named in the abstract and in the title of US2018236130A1 — Amelogenin-Chitosan Hydrogel for Dentin Hypersensitivity, which claims occlusion of dentinal tubules with apatite crystals.
