Pulp, Successional Lamina, and Vestibular Lamina Flashcards
1
Q
What tissue is the pulp derived from?
What does this tissue form?
A
- Mesodermal tissue of dental papilla
- VAN, lymph, connective tissue
2
Q
What is successional lamina?
A
A lingual growth which develops from the dental lamina to form succedaneous teeth
3
Q
What are succedaneous teeth?
A
Teeth that replace primary teeth, ie incisors, cuspids, and bicuspids
4

A
It goes through bud, cap, and bell stages just like the original dental lamina that had formed the deciduous teeth
5

What is a vestibule?
A
A channel that serves as an entrance to another cavity
6
Q
A channel that serves as an entrance to another cavity
A
Vestibule
7
Q
Describe the steps to develop vestibular lamina:
A
- Oral epithelium thickens in facial area of enamel organ
- Thickened layer clefts to form a vestibule, which forms the mucobuccal mucolabial folds
- This forms a future vestibule, the empty space located between the cheeks/lip and the teeth
8
Q
What other folds are formed when the vestibule is formed?
A
Mucobuccal and mucolabial
