how is the 2017 disease classification graded?
1 - health
2 - plaque induced gingivitis (localised/ generlised)
3 - non plauqe induced gingival diseases nd conditions
4 - periodontitis
- periodontitis***
- localised (<= 30 teeth)
- molar incisor pattern>
5- necrotising perio diseases
6 - perio as a manifestation of systemic
7 - systemic disease or conditions affecting the periodontal tissues
8 - perio bscesses
9- perio-endo lesions
10- micogongival deformities and conditons
how is clinical gingival health characterised?
absence of
-bleeding on probing
- erythema
- edema,
- patient symptoms,
- attachment and bone loss
what are the physiological bone levels range for clinical gingival health?
1.0 to 3.0 mm apical to the cemento-enamel junction
how is gingival health defined?
- For an intact periodontium and a reduced and stable periodontium
- gingival health is defined as < 10% bleeding sites with probing depths ≤3 mm
what is plaque induced gingivitis - intact periodontium?
BPEs 2 and no radiological bone loss and no interdental recession
what is bleeding on probing in relation to localised or generalised?
<30% - localised
>30% - generalised
what differentiates health and gingivitis
health <10% BOP
gingivitis >10% BOP
what are plaque induced gingivitis modifying factors?
A. associated with bacterial dental biofilm only
B. potential modifying factors of plaque induced gingivitis
1. systemic conditions
a) sex steroid hormones
-puberty
- Menstrual cycle
- pregnancy
- oral contraceptive
b) hyperglcemia
c) leukemia
d) smoking
e) malnutrition
2. oral factors enhancing plaque accumulation
a) prominent subgigival restoration margins
b) hyposalivation
C. drug-influenced gingival enlargements
what is plaque induced gingivitis - modified by puberty?
can be BPE 3s
no radiological bone loss
no interdental recession
types of plaque induced gingivitis?
modified by puberty
modified by poor restorative margins
drug influenced gingival enlargement
what are non plaque induced gingival diseases?
- Genetic/developmental e.g. hereditary gingival fibromatosis
- Specific infections e.g. herpetic gingival stomatitis, Candida albicans
- Inflammatory/immune conditions – e.g. lichen planus
- Inflammatory/immune conditions e.g. benign mucous membrane pemphigoid
- Nutritional deficiency e.g. vitamin C deficiency
what may occur in severely immune compromised nercotising periodontitis patients?
bone sequestrum
what are necrotising perio diseases?
- necrotising gingivitis
- necrotising periodontitis
what is a type of rare diseases that affect the course of periodontitis resulting in the early presentation of severe periodontitis.?
o Papillon Lefevre Syndrome
o leucocyte adhesion deficiency
o hypophosphatasia
o Down’s syndrome
o Ehlers-Danlos
what are a more heterogeneous group of conditions which result in breakdown of periodontal tissues and some of which may mimic the clinical presentation of periodontitis.
o squamous cell carcinoma
o Langerhans cell histiocytosis
what is recession type 1 for gingival recession?
- Gingival recession with no loss of inter‐ proximal attachment.
- Interproximal CEJ is clinically not detect‐ able at both mesial and distal aspects of the tooth.
what is recession type 2 for gingival recession?
- Gingival recession associated with loss of interproximal attachment.
- therefore total interproximal attachment loss < buccal attachment loss
- ip-(measured from the interproximal CEJ to the depth of the interproximal sulcus/pocket) b- (measured from the buccal CEJ to the apical end of the buccal sulcus/pocket).
what is recession type 3 for gingival recession?
- Gingival recession associated with loss of interproximal attachment.
- total interproximal attachment loss > buccal attachment loss
- ip- (measured from the interproximal CEJ to the apical end of the sulcus/pocket) b- (measured from the buccal CEJ to the apical end of the buccal sulcus/pocket)
what is this
pregnancy epulis
what is this
necrotising gingivitis
what is this
necrotising periodontitis
what type is this
recession type 1
what type is this?
