Periodontal Health, Gingival Disease:Conditions Flashcards
Periodontal Health
Absence of clinically detectable inflammation A state free from inflammatory periodontal disease
potential impacts of gingival dx
Importance of determining gingival health
To find the common reference point for assessing disease and determining the meaningful treatment outcomes.
Gingival Epitheliums
Oral epithelium
Sulcular epithelium
Junctional epithelium
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
- Gingival Connective Tissue contents
Connective tissue presents a diffuse, amorphous ground substance and collagen fibers.
Blood vessels stand out clearly in the papillary projections of the connective tissue.
Correlation of Clinical and
Microscopic Features
Correlation of Clinical and
Microscopic Features: color (wnl)
- Coral pink on marginal/attached gingiva
- Red smooth shiny on alveolar mucosa
- physiologic pigmentation
Correlation of Clinical and Microscopic Features:
size corresponds to what?
: Should corresponds with the total of the bulk of cellular and intercellular elements and vascular supply
- Consistency wnl
- Consistency: Firm and
resilient (gingival fibers)
Surface texture wnl
Surface texture: Stippled on
the attached gingiva
contour wnl
scalloped and collar-like fashion
gingival shape wnl
Shape: Pyramidal towards the anterior, flattened towards the posterior
Position of gingiva wnl
how can this be different?
The level at which the gingival margin is attached to the tooth
can be different due to eruption patterns (continuous eruption-active and passive-altered passive eruption)
Etiologic Factors
host determinants
microbe determinants
environmental determinants
host determinants of gingival health
Local predisposing factors:
Periodontal pockets
Restorations
Root anatomy
Tooth position and crowding
Systemic modifying factors:
* Host immune function
* Systemic health
* Genetics
microbial determinants of gingival health
Supragingival plaque
Subgingival plaque
environmental determinants of gingival health
Smoking
Medication
Stress
Nutrition
Indicators for gingival dx
BOP
probing
radio features
tooth mobility
BOP
light pressure 0.25N
can probing be used for diagnosis alone?
no
radio features of dx
Lamina dura
The distance of 2mm from the most coronal part of the alveolar crest to CEJ (max distance for WNL)
tooth mobility as a diagnosis
Not recommended

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 present with what periodontium?
In a reduced periodontium
Periodontal disease remission/control
In a reduced periodontium
Control modifying factors and therapeutic response
Treatment Goals
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.
which gingival epthelium are non-keratinized?
junctional epithelium and sulcular
induced forms of gingivitis
plaque and non-plaque induced
supracrestal tissue attatchment diagram
common pt complaints regarding gingiva
*Bleeding when brushing
*Blood in saliva
*Gingival swelling and redness
*Halitosis
common clincal observations
*Bleeding on gentle probing
*Increased gingival crevicular fluid production rate
*Change in gingival clinical features
Bleeding on Probing
when can this be seen?
predictor of?
smoking?
- 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
BOP under the 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=chronic stage)
