Study Notes
Periodontal Ligament Composition
- Collagen type I is the primary type of collagen found in the periodontal ligament.
- The principal fiber group within the periodontal ligament is the oblique group, which plays a critical role in withstanding occlusal forces.
Periodontal Ligament Development
- The epithelial root sheath is the sheath of inner and outer epithelial cells that forms during the development of the periodontal ligament.
Oral Cavity Protective Tissues
- The mucosa, also known as the mucous membrane, constitutes the protective tissues of the oral cavity.
- The oral mucosa is continuous with the digestive tract, forming a protective barrier.
