diagnosis and classification of PDD

Question 1

2017 classifications involved in PDD

Answer 1

1) periodontal health, gingival conditions and diseases
2) periodontitis
3) other conditions affecting the periodontium
4) peri implant diseases and conditions

Question 2

staging and grading system

Answer 2

4 stages of severtiy (1-4)

3 grades based on disease succeptibiloty

Question 3

WHO health

Answer 3

• health is a complete sate of physical mental and social wellbeing and not merely absence of disease and infirmity

Question 4

periodontal and gingival health

Answer 4

abscence of clinically detectable inflammation
bone levels 1-3mm apical to CEJ
clincial health can be restoed following treatment of gingivitus and PDD

Question 5

gingivitus dental biofilm induced

Answer 5

An inflammatory lesion resulting from interactions between plaque and the hosts immune inflammatory response
confined to gingiva

Question 6

diagnosing gingivitus

Answer 6

more than 10% bleedingsites

Question 7

risk factors

Answer 7

Local risk factors
-	retentive factors
-	removal will reduce plaque retention
Systemic risk factors
-	smoking
-	offer smoking cessation
-	root surface debridement would not be feasible

Question 8

drug induced gingival enlargment

Answer 8

consult with doctor to change medication

Question 9

gingival diseases non dentlalbiofilm induced

Answer 9

conditons not caused by plaque and not resolved following plaque removal
- inflammation may be beyond the mucogingival junction

Question 10

forms of PDD

Answer 10

necrotising PDD
peridontisis as a manifestation of systemic disease
peridonttis

Question 11

necrotising PDDs

Answer 11

necrotising gingivitus
necrotising periontitis
necrotising stomatitis

Question 12

necrotising gingivitus symtoms

Answer 12

• gingiva inflamed and red
• dental papilla has broken down
• gingivitis so no bone loss
• ulceration, necrosis, pain, halitosis

Question 13

necrotising periodontits l

Answer 13

loss of supporting strucutre and bone loss

Question 14

necrotising stomatitis

Answer 14

loss of flesh

Question 15

genetic disroders involved in peridonttis as a manifestation of systemic disease

Answer 15

erlos danlos syndrone

papillion lefeve

Question 16

Ehleres Danlos syndrome

Answer 16

• heteroflexibility of joints
• increased bleeding and bruising
• hyper extensible skin
• underlying molecular abnormality of collagen

Question 17

papillion lefevre

Answer 17

• affects primary and secondary dentition
• normal dental development until hyperkeratosis of palms and soles appear
• mechanism poorly understood
• mobility , periodontal destruction, bone loss, loss of teeth, breakdown of supporting tissues, inflamed gingiva

Question 18

orgin of periodontits associated with endodontic lesions

Answer 18

1) periodontal origin
2) endodontic origin
3) combination of both

Question 19

periodontitis clincial showings

Answer 19

• inflame gingiva
• gingival recession
• loss of dental papilla
• abscesses
• bleeding inflamed

Question 20

stages of peridontitis

Answer 20

Stage I: Initial periodontitis
Stage II: Moderate periodontitis
Stage III: Severe periodontitis
Stage IV: Very severe periodontitis

Question 21

grades of periodontitis

Answer 21

i. Grade A: slow rate of progression
ii. Grade B: moderate rate of progression
iii. Grade C: rapid rate of progression

Question 22

systemic diseases/condition affecting periodntal supporting tissues

Answer 22

genetic disorders
acquired immunodeificeicny diseass
inflammatory diseases
other systemic disorders

Question 23

mucrogingival deformities and conditions indications t to chekc

Answer 23

• gingival phenotype
• interproximal attachment loss
• characteristics of exposed root surface

Question 24

traumatic occlusal forces

Answer 24

any force which results injurt to the teeth

Question 25

peri implant health

Answer 25

absence of erythema, bleeding on probing, swelling and suppuration

• No increase in probing depth compared to previous examinations
• Absence of bone loss beyond crestal bone level changes resulting from initial bone remodeling

Question 26

periimplant mucositis

Answer 26

Characterized by bleeding on gentle probing, erythema, swelling and/or suppuration may be present

• Increased pocket depth often seen due to swelling or decrease in probing resistance
• Absence of bone loss beyond crestal bone level changes resulting from initial bone remodeling

Question 27

what is peri implant mucosisis likely to be caused by

Answer 27

plaque biofilm

Question 28

peri implantitis and what its characterised

Answer 28

Plaque associated pathological condition occurring in tissues around dental implants,
- characterised by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone(distal aspects of radiograph)

Question 29

what is peri implant mucosisitis assumed to precede

Answer 29

peri implantitis

Question 30

peri implant soft and hard deficienceis

Answer 30

diminited dimentsions of the alveolar process/ridge that reusult in both hard and soft tissues deficiences

Question 31

risk factors associated with recession of peri implant musocsa

Answer 31

• Mispositioning of implants
• Lack of buccal bone
• Thin soft tissue
• Lack of keratinized tissue
• Surgical trauma

Question 32

dignosis statment when dignosing PDD

Answer 32

1. Determine type of disease
2. Disease extent – localised/generalised/molar-incisor
3. Stage – I, II, III, IV
4. Grade – A / B / C
5. Current disease status – stable/remission/unstable
6. Risk factor profile – smoking/diabetes
