Study Notes

Aging and Periodontium

Aging is characterized as a disintegration of balanced control and organization, leading to decreased functional ability of organs.
Aging of an organ is defined as post-maturational deteriorative changes that increase vulnerability to challenges.

Effects of Aging on Periodontium

Thinning of gingival epithelium:
- Decreased keratinization
- Increased epithelial permeability to pathogens
- Decreased resistance to functional trauma
Changes in connective tissue:
- More dense and coarse
- Qualitative and quantitative changes to collagen
- Increased collagen stabilization
Decreased number of fibroblasts, irregular structure, and decreased organic matrix production
Decreased epithelial cell rests and collagen fibers, reducing tissue elasticity

Changes in Periodontal Ligament (PDL)

Decreased number of cells with reduced mitotic activity
Changes in width of PDL and decreased vascularity
Greater number of elastic fibers
Increased width of cementum (5-10 times) with age, especially apically and lingually

Changes in Alveolar Bone

Increased osteoporosis and decreased vascularity
Bone resorption increased or decreased
Greater irregularity in surface facing PDL

Effects of Aging on Periodontal Disease

Increased dentogingival plaque accumulation with age and increasing surface area
Changes in subgingival plaque composition, with increased enteric rods and pseudomonads in older adults
Periodontal pathogens, including P. GINGIVALIS, play a more significant role in older adults

Response to Treatment

No differences in response to non-surgical or surgical treatment have been shown for periodontitis
Importance of plaque control and effective periodontal therapy to prevent disease progression with age
