Odontogenesis II Flashcards
1
Q
Bell stage
A
Dental papilla cells mature into odontoblasts - forming predentine to dentine
2
Q
Crown stage
A
IEE cells mature into ameloblasts - forming enamel
3
Q
cervical loop
A
The most cervical portion of the enamel organ where the IEE and OEE cells meet and start interacting with the ectomesenchyme which will trigger differentiation. It is responsible for root development and the signal from DP to IEE at the cervical loop controls the number of cell deviations
4
Q
What cells can be seen in the late bell stage
A
Dental papilla, functioning odontoblasts, and pre-ameloblasts. A layer of Pre-dentine forming will stimulate the ameloblasts to synthesise and secrete enamel protein
5
Q
How and when does tooth shape occur?
A
- Occurs during late cap and early bell stage
- Tooth shape is determined from mesenchyme
