What would code 0/1/2 indicate?

Answer 1

Gingivitis

Question 2

How is gingivitis split?

Answer 2

1. Clinical gingival health - BOP <10%
2. Localised gingivitis - BOP 10-30%
3. Generalised gingivitis - BOP >30%

Question 3

What should diagnosis include if BPE of 2?

Answer 3

Comment on plaque retentive factors

Question 4

What would you do if code 3?

Answer 4

Radiographic assessment/ localised 6 point charting
If no pockers >4mm and no radiographic evidence bone loss - continue code 0/1/2 pathway
If pocket >4mm and/or radiographic evidence continue with code 4 pathway

Question 5

What does code 4 indicate?

Answer 5

Periodontitis

Question 6

How is periodontitis split?

Answer 6

1. Molar-incisor pattern
2. Localised perio <30% teeth
3. Generalised perio >30% teeth

Question 7

How stage/grade?

Answer 7

Use radiograph and use worst site

Question 8

What is staging?

Answer 8

Interproximal bone loss
Stage 1 - mild <15%
Stage 2 - moderate - coronal third root
Stage 3 - severe - mid third root 
Stage 4 - very severe - apical third root

Question 9

What is grading?

Answer 9

Progression of bone loss -> %bone loss/ pt age
A- slow progression <0.5
B - moderate progression 0.5-1.0
C - rapid rate progression >1.0

Question 10

How assess current periodontal status?

Answer 10

1. Currently stable - BOP <10%, PPD <4mm
2. Currently remission - BOP >10%, PPD <4mn, no BOP 4mm+ sites
3. Currently unstable - PPD >5MM or PPD >4mm and BOP
