Study Notes
Root Development
- The epithelial root sheath covers and molds the shape of the root.
Epithelial Root Sheath
- The purpose of the epithelial root sheath is to shape the root.
- The epithelial root sheath covers the root during development.
Ameloblasts
- The cells of the epithelial root sheath may differentiate into fully functioning ameloblasts during development.
- The enamel produced by fully functioning ameloblasts is called embryonic enamel.
Importance of Epithelial Root Sheath Adhesion
- If the cells of the epithelial root sheath do not remain adherent to the dentin surface during development, defects may occur in the root shape.
