What does teh periodontium include?
- Cementum
- Alveolar bone
- Periodontal ligament
Where does the periodontium originate?
Mesencmal cells
These are groups of epithelial cells the become located near the cementum in the mature PDL after the disintegration of the ____ during the formation of the root.
- Epithelial rests of Malassez
- Heartwig's epitheilial root sheeth
What is the main type of cell in the PDL?
Fibroblast-clast
What are the componenets of the PDL?
- Blood vessels
- Endothelial vasular lining cells
- Odontoblasts/clasts
- Mesencymal cells
- Nerve supply
- Macrophages for defense
These are elastic fibers taht stretch and contract during mastication. Interface with collagen bundles to provude support.
Oxytalan fibers
This is the space located between the budles of principal fibers that carry the vascular, neural, and lymphatics. It helps maintain tooth vitality.
Interstitial space
Where does the blood supply for the PDL stem from?
Branches of the superior and inferior alveolar arteries
