Perio Classifications

Question 1

Describe how you would assess a patient with a BPE of 1?

Answer 1

(Band completely visible with Bleeding and plaque present)

Assess the extent of bleeding
< 10% = clinical gingival health
10-30% = Localised gingivitis
> 30% = generalised gingivitis

Question 2

Describe how you would assess a patient with a BPE of 2?

Answer 2

(Band completely visible with Bleeding and plaque retentive factors)

Assess the extent of bleeding
< 10% = clinical gingival health
10-30% = Localised gingivitis
> 30% = generalised gingivitis

and diagnosis should comment on plaque retentive factors present

Question 3

Describe how you would assess a patient with a BPE of 3?

Answer 3

(Band partially visible)

Take radiographs

start initial therapy and reassess after 3 months

After 3 months take a localised 6ppc

Pockets < 4mm and no radiographic signs on perio bone loss = treat as you would code 0,1,2

Pockets ≥ 4mm with radiographic signs of perio bone loss = treat as you would code 4

Question 4

Describe how you would assess a patient with a BPE of 4?

Answer 4

(Band disappears)

Take radiographs

GDH say Start treatment and do a 6ppc for whole mouth post treatment

assess if patient has:
Molar incisor pattern
Localised perio = <30%
Generalised perio = ≥ 30%

Stage, grade, risk factor assessment and current disease status

Question 5

How do you stage a perio patient?

Answer 5

Use the site with the maximum inter proximal bone loss and asses the severity.

Question 6

Define a stage 1/mild perio patient.

Answer 6

Bone loss is < 15% (2mm) at worst site

Question 7

Define a stage 2 perio patient.

Answer 7

Bone loss reaches coronal 3rd at worst site

Question 8

Define a stage 3 perio patient.

Answer 8

Bone loss reaches mid 3rd at worst site

Question 9

Define a stage 4 perio patient.

Answer 9

Bone loss reaches apical 3rd at worst site - or lost a tooth to perio

Question 10

if a patient has lost teeth to perio previously what stage do they get?

Answer 10

stage 4

Question 11

How do we grade perio patients?

Answer 11

Use the site with the worst percentage bone loss and divide by the patients age

Question 12

Define a grade A perio patient.

Answer 12

< 0.5

Question 13

Define a grade B perio patient.

Answer 13

0.5 - 1

Question 14

Define a grade C perio patient.

Answer 14

> 1

Question 15

How do we measure the extent of the perio disease? (3)

Answer 15

• Molar incisor pattern
• <30% = localised
• ≥ 30% = generalised

Question 16

Describe a currently stable periodontal status.

Answer 16

< 10% Bleeding sites

pockets of ≤ 4mm with no bleeding

Question 17

Describe a currently in remission periodontal status.

Answer 17

≥ 10% bleeding sites

Pocket depths ≤ 4mm

no bleeding at 4mm sites

Question 18

Describe a currently unstable periodontal status.

Answer 18

pocket depths of ≥ 5mm
or
PPD ≥ 4mm & BoP.
