Periodontal Health, Gingival Disease:Conditions Flashcards
Periodontal Health
Absence of clinically
detectable inflammation A state free from inflammatory periodontal disease
Periodontal Health
“A state free from inflammatory
periodontal disease that allows an
individual to function normally and
avoid consequences (mental and
physical) due to current or past
disease.”

Cardiovascular diesases
Respiratory disease
Diabetes

Importance
To find the common —
for assessing disease and determining
the meaningful treatment outcomes.

- Gingival Epithelium
- Gingival Connective Tissue
Oral epithelium
*Keratinized, turnover rate 30
days
Sulcular epithelium
*Non-keratinized, no rete pegs,
semipermeable membrane
Junctional epithelium
*Non-keratinized, attached via
hemidesmosomes, infiltrate by
PMN, turnover rate 7-10 days
Microscopic
* Gingival Connective Tissue
(2)
Connective tissue presents a
diffuse, amorphous ground
substance and collagen fibers.
Blood vessels stand out clearly in
the papillary projections of the
connective tissue.

Pristine periodontal health
Total absence of of clinical inflammation and physiological immune surveillance with no attachment or
bone loss
Not likely to be observed clinically
Clinical periodontal health
Absence or minimal levels of clinical inflammation in a periodontist with no attachment or bone loss
Periodontal disease stability
In a reduced periodontium
Periodontal disease remission/control
In a reduced periodontium
Control modifying factors and therapeutic response
Clinical gingival health can be restored following treatment. However,
the treated and stable periodontitis patient with
current gingival health remains at increased risk of
recurrent periodontitis, and must be closely monitored.
Gingivitis
“Gingivitis is the inflammation of the
gingival tissues without loss of
connective tissue attachment.”
Bleeding on Probing
(4)
- One of the early signs
- Prior to color change or other visual signs of inflammation
- Excellent negative predictor (absence of BOP) of future
attachment loss - Smoking masks BOP by suppressing inflammatory response
Early sign: bleeding on probing Under microscope
- Dilation and engorgement of the
capillaries and thinning or ulceration
of the sulcular epithelium - Vasculitis of blood vessels adjacent to
the junctional epithelium - Progressive destruction of the
collagen fiber network (collagen-poor) - Cytopathologic alterations of resident
fibroblasts (cell-rich) - Progressive infiammatory immune
cellular infiltrate (predominantly
lymphocytic)

• Sloughing with grayish,

gingivitis ( 40% patients have stippling)
