    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.
