    Study Notes

    Attachment Loss in Periodontal Pockets

    • Characterized by destruction of fibers and bone
    • Affects teeth support, spreading apically and laterally
    • Can vary in depth on different root surfaces

    Disease Sites

    • Areas of tissue destruction
    • Inactive disease site: junctional epithelium attachment level stays the same over time
    • Active disease site: shows continued apical migration of junctional epithelium
    • Assessed using a periodontal probe

    Periodontal Pockets

    • Areas of tissue destruction left by disease
    • Not always an indicator of active disease
    • Majority of pockets in adult patients are inactive disease sites

    Gingival Sulcus

    • Average depth in a healthy mouth is 1 to 3mm
    • Junctional epithelium sits coronal to CEJ
    • Attaches along the entire length of the tooth

    Gingival Pockets or Pseudopockets

    • A deepening of the gingival sulcus due to swelling
    • Increased probing depth due to:
      • Detachment of the coronal portion of junctional epithelium
      • Increased tissue size from swelling
    • False pockets

    Periodontal Pockets

    • Pathological deepening of the gingival sulcus
    • Results of:
      • Apical migration of junctional epithelium
      • Destruction of periodontal ligament fibers
    • Travels into the periodontal ligament space

    Pathway of Inflammation in Vertical Bone Loss

    • Travels through gingival connective tissue, into the periodontal ligament space and into the alveolar bone.
    • Weakened crestal periodontal ligament fibers no longer provide a barrier

    Bone Defects in Periodontitis

    • Infrabony defect: base of the defect extends apical to the residual alveolar crest
    • Intrabony defect: bone resorption occurs in an uneven, oblique direction, primarily affects one tooth

    One-Wall Intrabony Defect

    • Also known as a hemiseptal defect
    • Half of the interdental septum is lost
    • Other half remains attached to the tooth

    Two-Wall and Three-Wall Intrabony Defects

    • Multiple walls of alveolar bone lost

    Proximal Bone Contour

    • Bone contour from facial to lingual dips apically
    • Forms osseous crater
    • Affects two adjacent root surfaces
    • Interdental area difficult to clean

    Bone Loss in Furcation Areas

    • Furcation involvement occurs on multirooted teeth when periodontal infection reaches the area between and around roots
    • Alveolar bone loss between the roots
    • May be hidden by gingival tissue or visible clinically
    • Bleeding upon gentle probing
    • Probing depths greater than 3 mm

    Microscopic Picture of Gingivitis

    • Hemidesmosomes remain attached to enamel
    • Epithelial ridges extend from junctional epithelium into adjacent connective tissue zone
    • Reversible damage to gingival fibers
    • No infection in alveolar bone or periodontal ligament fibers, cementum is normal

    Periodontitis

    • Permanent tissue destruction

    Characteristics of Periodontitis

    • Apical migration of junctional epithelium
    • Loss of connective tissue attachment
    • Loss of alveolar bone
    • Tissue destruction occurs intermittently at different rates throughout the mouth

    Clinical Picture of Periodontitis

    • Visible alterations in color, contour, and consistency
    • Gingival margin may be swollen or fibrotic
    • Interdental papillae may balloon out or be blunted
    • Bleeding upon probing
    • Suppuration (pus) possible
    • Pocket depths of 4mm or greater

    Microscopic Picture of Periodontitis

    • Apical migration of junctional epithelium, coronal portion detaches from tooth surface
    • Extracellular matrix of gingiva and collagen fibers destroyed
    • Junctional epithelium and sulcular epithelium extend into the connective tissue
    • Small ulcerations of pocket epithelium expose underlying inflamed connective tissue
