Periodontal Structures in Aging Humans
Periodontal Structures In Aging Humans Important Notes
1. Aging in the gingiva
- Thinning and reduced keratinization
- Increase in epithelial permeability
- Flattening of recipes
- Increase in width of attached gingiva
- Migration of junctional epithelium apically
2. Aging in the periodontal ligament
- Decreased cellularity
- Decreased vascularity
- Decreased mitotic activity
- Decrease in the number of collagen fibers
- Increase in arteriosclerotic changes
- Decrease in the number of epithelial rests of Malassez
- Increase in diameter of a collagen fiber bundle
- Increase in cementless
3. Aging in cementum
- The smooth surface becomes irregular
- Hypercementosis
- The permeability of cementum decreases with age
- Increase in cemental width
- Accumulation of resorption bays
4. Aging in alveolar bone
- The irregular periodontal surface of a bone

Question 1. Aging and Periodontium.
Answer:
Age Changes In Gingiva:
1. Epithelium:
- Thinning of epithelium
- Decreased Keratinization
- Passage of bacteria into connective tissue
- The greater amount of intracellular substance
2. Connective Tissue:
- ↓ connective tissue cellularity
- ↓oxygen consumption
- ↑ mast cell
- Atrophy of CT
3. Macroscopic:
- Gingival recession
- Passive eruption of the tooth
- ↑ denaturing temperature
Age Changes in Periodontal Ligament:
↓ Vasucalarity
Elastic fibers
↓ organic matrix
↑ width with less number of teeth present
↓ mitotic activity
↓ collagen fibers
↓ width with ↓ masticatory muscle strength

Age changes in alveolar bone
Osteoporosis
↓ Vascularity
↓metabolic rate
↓ healing capacity
↓bone formation ↑ bone resorption
Age changes in cementum:
↑ cemental width, more apically and lingually
