In this review paper, features of the hierarchical or-ganization of enamel elements of human teeth at macro, micro and submicron levels are shown. At the macro-structural level, the spherulite-zonal structure of the enamel apatite is due to the radial arrangement of prisms and semi-concentric bands (Retzius surfaces). For the first time, complex types of subordinate struc-tures of the structural order of subelements in enamel prisms have been established. The basic microstructural element of the enamel — prism can be represented in the form of a biocomposite composed of co-ordinated systems in the following sequence: globular nanoparti-cles → nanofibrils → subindivids → chain aggregates of subindivids → blocks → filamentary crystal (enamel prism). Unified structure-forming tendencies of the apa-tite enamel and of abiogenic natural mineral structures have been noted.

Keywords: enamel prism, apatite, structural ele-ments, crystal, subindivids.
