Development of the Root Flashcards
When does the root begin to form?
After the outline of the crown has been established and before the crown is calcified, after the enamel and coronal dentin is laid down
What happens after the outline of the crown has been established and before the crown is calcified?
The root begins to form
What is the cervical root?
- The deepest part of the enamel organ
- Where OEE cells encounter IEE cells
What is the deepest part of the enamel organ?
The cervical root
What is the point where OEE cells encounter IEE cells?
Cervical root
What only contains OEE and IEE cells and is located apical to the crown?
Epithelial root sheath
What is the epithelial root sheath?
Only contains OEE and IEE cells and is located apical to the crown
The epithelial root sheath does NOT contain any…
Stratum intermedium or stellate reticulum
What is the epithelial diaphragm?
The turned in portion of the epithelial root sheath
What cells make up the epithelial diaphragm?
OEE and IEE
What happens as the root sheath grows downwardly?
Peripheral dental papilla cells become odontoblasts, radicular dentin begins to form
When does radicular dentin begin to form?
When the root sheath grows downwardly and peripheral dental papilla cells become odontoblasts
