Q

Why is prevention and management of periodontal disease essential?

A

can cause tooth mobility, drifting of teeth, tooth loss

can lead to low self esteem, reduction in functional capacity, impacts social relationships and quality of life

16
Q

clinical presentation of periodontitis

A 
Formation of periodontal pockets
Bleeding on probing
Gingival inflammation
Drifting of teeth
Tooth Mobility
Gingival recession
17
Q

radiographic presentation of periodontitis

A

Loss of alveolar bone - >1.5mm apical to CEJ

18
Q

diagnosis of periodontitis using 2017 classification

A

pattern, stage, grade, stability, risk factor profile

19
Q

pattern of periodontitis

A

localised <30% teeth
generalised >30% teeth
molar-incisor (only involving molars or incisors

20
Q

staging in full

A

Assessment of greatest site of clinical attachment loss
Assessment of radiographic bone loss
Assessment of tooth loss due to periodontitis
Maximum pocket depth
Furcation involvement
Occlusal trauma

21
Q

staging in BSP modification

A

assessment of radiographic bone loss

22
Q

stage of periodontitis using worst site of inter-proximal bone loss due to periodontitis

A

Stage I
(early/mild)<15% or <2mm –> only use mms if only bitewing radiograph available or no radiographs clinically justified

Stage II
(moderate)Coronal third of root

Stage III
(severe)Mid third of root

Stage IV
(very severe)Apical third of root

23
Q

Grading BSP modification

A

ratio of percentage bone loss to age

24
Q

grade of periodontitis using worst site of bone loss divided by age

A 
Grade A (slow) <0.5
Grade B (moderate) 0.5-1.0
Grade C (rapid) >1.0

Grade A: Maximum bone loss is less that half the patient’s age
Grade C: Maximum bone loss is greater than the patient’s age
Grade B: All other situations

25
Q

risk factor for periodontitis status

A 
Smoking
Poorly-controlled diabetes
Family history
Poor plaque control
Subgingival deposits of calculus
Local factors: mouth-breathing, crowding
26
Q

determining a diagnosis

A
  1. condition
  2. distribution
  3. classification (stage, grade)
  4. stability
  5. risk factor profile
