Classification

Question 1

how is the 2017 disease classification graded?

Answer 1

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

Question 2

how is clinical gingival health characterised?

Answer 2

absence of
-bleeding on probing
- erythema
- edema,
- patient symptoms,
- attachment and bone loss

Question 3

what are the physiological bone levels range for clinical gingival health?

Answer 3

1.0 to 3.0 mm apical to the cemento-enamel junction

Question 4

how is gingival health defined?

Answer 4

• For an intact periodontium and a reduced and stable periodontium
• gingival health is defined as < 10% bleeding sites with probing depths ≤3 mm

Question 5

what is plaque induced gingivitis - intact periodontium?

Answer 5

BPEs 2 and no radiological bone loss and no interdental recession

Question 6

what is bleeding on probing in relation to localised or generalised?

Answer 6

<30% - localised
>30% - generalised

Question 7

what differentiates health and gingivitis

Answer 7

health <10% BOP
gingivitis >10% BOP

Question 8

what are plaque induced gingivitis modifying factors?

Answer 8

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

Question 9

what is plaque induced gingivitis - modified by puberty?

Answer 9

can be BPE 3s
no radiological bone loss
no interdental recession

Question 10

types of plaque induced gingivitis?

Answer 10

modified by puberty
modified by poor restorative margins
drug influenced gingival enlargement

Question 11

what are non plaque induced gingival diseases?

Answer 11

• 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

Question 12

what may occur in severely immune compromised nercotising periodontitis patients?

Answer 12

bone sequestrum

Question 13

what are necrotising perio diseases?

Answer 13

• necrotising gingivitis
• necrotising periodontitis

Question 14

what is a type of rare diseases that affect the course of periodontitis resulting in the early presentation of severe periodontitis.?

Answer 14

o Papillon Lefevre Syndrome
o leucocyte adhesion deficiency
o hypophosphatasia
o Down’s syndrome
o Ehlers-Danlos

Question 15

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.

Answer 15

o squamous cell carcinoma
o Langerhans cell histiocytosis

Question 16

what is recession type 1 for gingival recession?

Answer 16

• 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.

Question 17

what is recession type 2 for gingival recession?

Answer 17

• 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).

Question 18

what is recession type 3 for gingival recession?

Answer 18

• 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)

Answer 19

pregnancy epulis

what is this

Answer 20

necrotising gingivitis

Question 21

what is this

Answer 21

necrotising periodontitis

Question 22
