the presence of a range of developmental states from unmodified dentine to hypermineralized enameloid within polypterus teeth themselves and also in other parts of the dermal skeleton , as well as the combined origin of the tooth cap , demonstrates that the enamel/enameloid/dentine system forms a continuum of tissues that have diverged from one another by changes in the relative timing of developmental events and matrix production .
