Overview

enamel epithelium


Show Summary Details

Quick Reference

The cellular layer formed as part of the enamel organ. The columnar cells of the inner enamel epithelium line the inner surface of the enamel organ and define the shape of the crown of the tooth. They eventually differentiate into enamel-forming cells (ameloblasts). The outer enamel epithelium consists of a layer of cuboidal cells forming the external surface of the enamel organ. They maintain the shape of the enamel organ. The reduced enamel epithelium forms the remains of the ameloblast cell layer and protects the enamel during eruption. After eruption it becomes the junctional epithelium.
