Q

What is the BPE screening system and how does it work?

A

It is a screening tool to help reach a diagnosis. All new patients should have it recorded.
The codes for it are 0,1,2,3,4 and *. * means a furcation which is bone loss between roots. The dentition is divided into 6 sextants.
Record the highest score in each sextant.

2
Q

What are the increments on the BPE probe?

A

0.5mm ball
first black line - 3.5-5.5 mm
second black line - 8.5-11.5mm

3
Q

What do BPE codes 0, 1 and 2 mean?

A

Health of gingivitis.

0 = no calculus/overhands, no bleeding on probing, black band entirely visible

1 = no calculus/overhangs, bleeding on probing, black band entirely visible

2 = supra or sub gingival calculus/overhangs, black band entirely visible

4
Q

For 0, 1 or 2, how do we measure if it is localised or generalised gingivitis or heath?

A

We test % bleeding on probing.

<10% = gingival health
10-30% is localised gingivitis
>30% is generalised gingivitis

5
Q

For 3 or 4 - what do we do to measure extent?

A

BPE probe
black line partially showing = 3
black line completely not showing = 4

We then go on to stage and grade.
We do this by taking radiographs and pocket charts.

Molar-incisor pattern = periodontitis molar-incisor pattern

<30% teeth recession = localised periodontitis

> 30% tooth recession = generalised periodontitis

6
Q

How does staging work?

A

Looks at bone loss using worst site by dividing root into 3:

<15% (attachment loss from cej) = stage 1

Coronal third of root = stage 2

Mid third of root = stage 3

Apical third of root = stage 4

7
Q

How does grading work?

A

% bone loss / patient age

<0.5 = grade A
0.5-1 = grade B
>1 = grade C
8
Q

What categories come under assessment of current periodontitis status?

A
  1. Currently stable -
  2. Currently in remission
  3. Currently unstable
9
Q

How do we write a diagnosis statement?

A

Extent - Periodontitis - Stage - Grade - Stability - Risk Factors

10
Q

Give details on health and plaque induced gingitivits

A
No radiographs required
Bleeding on probing:
<10% = health
10-30% = localised gingivitis 
>30% = generalised gingivitis
11
Q

If we classify with periodontal health, what is the difference between intact periodontium and reduced periodontium?

A

Intact:

  • no probing attachment loss
  • probing pocket depths < 3mm
  • bleeding on probing <10%
  • no radiographic bone loss

Reduced:

  • Successfully treated periodontitis
  • Evidence of probing attachment loss
  • probing pocket depths < 3mm
  • bleeding on probing <10%
  • signs of radiographic bone loss
12
Q

Plaque induced gingivitis:

  • type of gingivitis
  • type of periodontium
A
  1. Can be localised or generalised depending on bleeding scores
  2. Can be intact or reduced depending on attachment loss and signs of radiographic bone loss
13
Q

What do we need to measure when diagnosing periodontitis?

A

Need to take radiographs and do a pocket chart.

Measure disease extent, staging, grading, current disease status and risk factor assessment.
