The Epithelial Root Sheath
Epithelial cells in the cervical loop continue to proliferate and form that portion of the dental organ concerned with root formation - the epithelial root sheath (of Hertwig). How many components of the dental organ can be identified in the epithelial root sheath? Pulp (A) occupies the right half of the field, the cells of its outer becoming odontoblasts (B) which continue down into the root. The cells of the IDE (C) are adjacent to this. A stratum intermedium (associated with enamel formation) is not present. A thin band of stellate reticulum (D) is present. The ODE (E) can also be identified.
