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
