Dental enamel 1 article

Dental enamel is the highly mineralized outer tissue covering the anatomical crown of a tooth. Its prism-based structure and high hydroxyapatite content give the crown a hard surface, yet enamel can undergo acid demineralization, erosion and carious breakdown because it has no living cells capable of true regeneration. Fluoride and remineralization processes act at the surface. Enamel is therefore distinct from dentin and pulp, which form the deeper structural and vital components of the tooth.
