Question 120 (part 2) · LDEK · Tooth development and mineralization
Arrange the formation stages of teeth, starting from the earliest:
1) histologic differentiation;
2) dental lamina formation;
3) matrix deposition;
4) migration of neural crest cells towards the ectomesenchyme of branchial arch;
5) eruption and root formation;
6) morphologic differentiation.
Correct answer is:
2) dental lamina formation;
3) matrix deposition;
4) migration of neural crest cells towards the ectomesenchyme of branchial arch;
5) eruption and root formation;
6) morphologic differentiation.
Correct answer is:
- A. 4,1,2,3,6,5.

- D. 4,6,1,2,3,5.
- E. 4,2,1,6,3,5.
Hint
Start with the embryonic event that supplies the mesenchyme of the jaws, then follow odontogenesis through to emergence of the tooth.
