Anatomical terminology

The inner enamel epithelium, also known as the internal enamel epithelium, is a layer of columnar cells located on the rim nearest the dental papilla of the enamel organ in a developing tooth. This layer is first seen during the bell stage, in which these inner enamel epithelium will differentiate into ameloblasts.

The location of the enamel organ where the outer and inner enamel epithelium join is called the cervical loop.
