    The outer enamel epithelium, also known as the external enamel epithelium, is a layer of cuboidal cells located on the periphery of the enamel organ in a developing tooth. ...

    en.wikipedia.org/wiki/Cervical_loop

    The cervical loop is the location on an enamel organ in a developing tooth where the outer enamel epithelium and the inner enamel epithelium join. The cervical loop is a histologic term indicating a specific epithelial structure at the apical side of the tooth germ, consisting of loosely aggregated stellate reticulum in the center surrounded by ...

    en.wikipedia.org/wiki/Epithelial_root_sheath

    The Hertwig epithelial root sheath (HERS) or epithelial root sheath is a proliferation of epithelial cells located at the cervical loop of the enamel organ in a developing tooth. Hertwig epithelial root sheath initiates the formation of dentin in the root of a tooth by causing the differentiation of odontoblasts from the dental papilla.

  5. Ameloblast - Wikipedia

    en.wikipedia.org/wiki/Ameloblast

    Reversal of nutrition - as long as the ameloblasts are in contact with the dental papilla, they receive nutrient material from the blood vessels of the tissue, but due to formation of this dentin the original source of nutrition is cut off and the ameloblasts are supplied by capillaries penetrating the outer enamel epithelium. This change in ...

    The other dominant hypothesis, the "clone model", proposes that the epithelium programs a group of ectomesenchymal cells to generate teeth of particular shapes. This group of cells, called a clone, coaxes the dental lamina into tooth development, causing a tooth bud to form. Growth of the dental lamina continues in an area called the "progress ...
