Study Notes
Gingivitis Development Stages
- Plaque-induced gingivitis progresses through four stages: initial, early, established, and advanced (periodontitis).
- Each stage has distinct histological changes and clinical manifestations.
Initial Stage (Stage I)
- Characterized by initial inflammation with no visible clinical changes.
- Increased migration of leukocytes and their accumulation in the gingival sulcus.
- Increased gingival fluid flow into the sulcus.
- Characterized by infiltration of PMNs (neutrophils).
Early Stage (Stage II)
- Develops within a week of plaque accumulation.
- Overlaps with the initial stage, but clinical signs of gingivitis may be present.
- Increased leukocyte infiltration in connective tissue, mostly lymphocytes, with some neutrophils, macrophages, plasma cells, and mast cells.
- Dense infiltration of neutrophils at the junctional epithelium and gingival sulcus.
- Rete pegs and ridges begin to develop.
- 70% of collagen is destroyed surrounding the cellular infiltrate.
- Circular and dentogingival fibers are affected.
Established Stage (Stage III)
- Characterized by moderate to severe gingivitis.
- Two types: stable (non-progressive) and active (progressing to periodontitis).
- Persistent inflammatory changes with more advanced infiltration of plasma cells.
- Blood vessels become engorged, congested, and blood flow becomes sluggish, resulting in localized gingival anoxemia.
- Reddish/bluish hue on the gingiva due to blood stasis and hemoglobin breakdown.
- Rete pegs and ridges are more prominent.
Advanced Stage (Stage IV)
- Characterized by extension of the lesion into alveolar bone.
- Periodontal breakdown occurs.
- Gingivitis progresses to periodontitis only in susceptible individuals.
Clinical Manifestations of Gingivitis
- Changes in Consistency: Firm, resilient gingiva becomes soft, friable, and bleeds easily due to edema and exudate.
- Changes in Surface Texture: Stippling, the orange-peel appearance of normal gingiva, is lost due to inflammation.
- Changes in Gingival Contour: The marginal gingiva can become swollen, receding, or exhibit Stillman’s clefts (recession with a V-shaped notch).
- Changes in Gingival Size: Gingival size is altered due to inflammation and changes in cellular and intercellular elements.
Gingivitis in Children
- Dental plaque biofilm-induced gingivitis is common in children, affecting up to 70% of children over 7 years old.
