Comparative observations on the ultra-structure of the inorganic and organic components of dental enamel

  • R. W. Fearnhead


Enamel covering the crowns of teeth consists principally of a mineral apatite which crystallises into an organic matrix of fibrous protein related to keratin. According to current opinion based on optical microscopy, fully formed enamel consists of calcified rods which are thought to be formed by columnar ectodermal cells called ameloblasts. Between the rods is a calcified inter-rod material. The origin and manner in which the ultra-structural components of the rod and inter-rod material are formed has not been satisfactorily demonstrated by optical methods.
