1
New cards
What are the three types of tooth movements?
Pre-eruptive, eruptive, and functional.
2
New cards
The pre-eruptive stage occurs prior to the initiation of what?
Root formation.
3
New cards
What is the role of pulpal pressure in tooth eruption?
Pulpal pressure contributes to force generation due to growth of pulpal cells and associated ECM expansion.
4
New cards
What happens during the eruptive stage of tooth movement?
Tooth emergence occurs as the reduced enamel epithelium (REE) fuses with oral epithelium, allowing for intraoral movement until clinical contact with the opposing crown.
5
New cards
What is the function of periodontal fibers in tooth eruption?
They exert traction and pull the tooth upward as they mature.
6
New cards
How does root elongation contribute to tooth eruption?
Root growth pushes the crown toward the oral cavity.
7
New cards
What is passive eruption?
Enlargement of the clinical crown due to gingival recession.
8
New cards
What systemic condition is associated with tooth eruption issues?
Osteopetrosis, which disrupts osteoclast function.
9
New cards
What is the primary cuticle and where is it formed?
A thickened basal lamina formed from the reduced enamel epithelium during tooth development.
10
New cards
How is the junctional (attachment) epithelium formed?
By the fusion of oral epithelium and reduced enamel epithelium.
