Perio - Classification Flashcards
How do we classify/provide a diagnostic statement for periodontal disease?
Type and extent, stage, grade, stable/unstable and the risk factors
T- generalised/localised E - local, general, MIP S - 1-4 G - A-C Stable/unstable = related to bleeding RF - smoking, uncontrolled diabetes
List the classifications of periodontal disease? (10)
- Health
- Plaque induced gingivitis
- Non plaque induced gingival diseases and conditions
- Periodontitis
- Necrotising periodontal diseases
- Periodontitis as a manifestation of systemic disease
- Systemic disorders affecting the periodontal tissues
- Periodontal abscesses
- Periodontal- endodontic lesions
- Mucogingival deformities and conditions.
how do we stage periodontal disease? (4)
use the worst affected site in the whole mouth
Stage 1 = Early/mild
< 15% of inter proximal bone loss at the worst site
Stage 2 = Moderate
Bone loss at coronal third of root
Stage 3 = Severe (potential for tooth loss)
Bone loss to the mid third of the root
Stage 4 = Very severe (potential for tooth loss)
Bone loss to the apical third of the root
what staging does a patient who has lost teeth before to peridontal disease get?
stage 4
how do we grade periodontal disease? (3)
Measured using the patients age and the percentage bone loss at the worst affected site.
Slow
if % bone loss / age = < 0.5
Moderate
if % bone loss / age = between 0.5 to 1.0
Rapid
if % bone loss / age = > 1
what percentage is generalised periodontal disease?
> 30%
what percentage is localised periodontal disease?
< 30%
what indicates that the disease is uncontrolled?
bleeding
what are the bleeding percentage in a healthy periodontium?
< 10%
what are cause of non-plaque induced gingival disease?
genetic/developmental disorders
e.g. Hereditary gingival fibromatosis
Specific infections
e.g. herpetic gingival stomatitis
Inflammatory and immune conditions
e.g. Lichen planus
Endocrine, nutritional and metabolic diseases
e.g. Vitamin C deficiency
what are predisposing factors to necrotising gingivitis/periodontitis In adults? (6)
HIV/Aids Immunosuppression Uncontrolled stress poor nutrition/malnourished smoking
all paired with gingivitis from poor oral hygiene
what are predisposing factors to necrotising gingivitis/periodontitis in children? (3)
Severe malnourishment
Extreme living conditions
Severe viral infections
what conditions are associated with Periodontitis as a manifestation of systemic diseases? (5)
Papillion Lefevre Syndrome Leukocyte adhesion deficiency Hypophosphatasia Down syndrome Ehlers- Danlos
describe recession type 1.
Gingival recession with no loss of inter-proximal attachment.
describe recession type 2.
Gingival recession associated with loss of inter proximal attachment.
The inter proximal attachment loss is LESS than/equal to the buccal attachment loss.
