Increased health awareness and improvements in preventive
dentistry have led to decreasing tooth loss for all age groups

Increased life expectancy and greater health expectations
= older patients demand, ask and expect for periodontal
treatments similar to that provided for the younger
individuals

Gingival epithelium
Gingival Connective tissue
Periodontal ligament
Cementum
Alveolar bone
Bacterial plaque
Immune responses
Progression of periodontal
disease
Response to periodontal
treatment

Gingival Epithelium
Thinning & decreased
keratinization
Flattening of rete pegs &
altered cell density
Increase in epithelial
permeability to bacteria &
its toxins
Decreased resistance to
functional trauma

Effects
of aging
on the
location of
Junctional epithelium?

Most reports suggested

B: Wear of incisal edge, continued tooth eruption, gingival
margins remain at the same position, root exposed
C: Wear of incisal edge, continued tooth eruption, entire
dentogingival complex has moved coronally
A: Normal
relationship

D: No incisal edge wear, gingival recession present

Gingival
Connective tissue

Increased
denaturing
temperature

Greater
content of
mature
collagen

Periodontal ligament
Decreased number of fibroblasts
Decreased organic matrix production &
epithelial cell rests
Increased amounts of elastic fibers
Depending on the functional status of the teeth,
Width of periodontal ligament space…

Decrease if tooth is
in hypofunction

Increase with
excessive occlusal
loading

“Deposition continues
after tooth eruption”
•Increase in cemental
width
•May increase 5-10
times with increasing
age
•Seen more in apical
and lingual aspects
•Increased surface
irregularity due to
accumulation of
resorption bays

Specific changes in
alveolar bone
Increased irregularity of
periodontal surface of bone
Less irregular insertion of
collagen fibers into the bone

For regenerative periodontal surgical procedures,
bone graft preparations obtained from donors more than 50
years old possess less osteogenic potential than younger
donors

There is no strong evidence demonstrating age-related
changes in host defense mechanisms in the elderly patients
with and without periodontal disease

progression of periodontal disease

Increased gingival index

Findings inconsistent with that of other studies…

Conclusions from majority of other studies suggest that
“the effects of age either is non-existent or provides a
small and clinically insignificant increased risk for loss
of periodontal support”
Hence, AGE is not a true risk factor but a background
or an associated factor for periodontal attachment
apparatus background
