Study Notes
Masticatory Mucosa
- The outer surface of the attached gingiva is masticatory mucosa.
- It's adapted to withstand chewing forces.
- This provides protection for the gingiva during mastication.
Keratinization
- The attached gingiva is usually keratinized, but the level varies.
- Healthy, non-inflamed gingiva shows orthokeratinization, with no visible nuclei in the keratinized cells.
- But parakeratinization, with visible nuclei, can happen in up to 75% of cases.
- Keratinization acts as a protective barrier, and its variability reflects the response to inflammation or mechanical stress.
Staining Characteristics
- Parakeratinized areas stain strongly pink with hematoxylin and eosin.
- This helps identify the level of keratinization and provides insights into the health of the gingival tissue.
Papillation and Papillae Arrangement
- The connective tissue papillae beneath the epithelium have variable arrangements, often in rows.
- This increases the surface area for nutrient exchange between the epithelium and connective tissue.
- It also strengthens the attachment between the gingival epithelium and underlying bone, which contributes to gingival stability.
Stippling
- The surface of the attached gingiva is stippled due to intersecting epithelial ridges.
- Stippling is a sign of healthy attached gingiva, reflecting its robust attachment to underlying tissues.
- It's a clinical indicator of the gingiva's health and integrity.
Absence of Submucosa
- The attached gingiva lacks submucosa.
- The lamina propria is directly bound to the bone, forming a mucoperiosteum.
- This direct attachment to the bone creates a firm and immovable gingiva.
- It contributes to gingival stability, preventing movement during mastication, which is crucial for maintaining periodontal health.
