Guidance on Interpretation of BPE Scores: 4

Answer 23

OHI, RSD (root surface debridement) . Assess the need for more complex treatment; referral to a specialist may be indicated

Question 24

Guidance on Interpretation of BPE Scores: *

Answer 24

Treat according to BPE Code 0-4. Assess the need for more complex treatment; referral to a specialist may be indicated

Sufficient plaque and bleeding levels
Modified Plaque Score <30%
Modified Bleeding Score <35%
>50% Improvement in both

Question 35

Answer 35

Insufficient self-care and OH
Insufficient plaque and bleeding levels

Question 36

Which probe is used in a BPE exam?

Answer 36

The WHO BPE probe has two black bands, at 3.5 to 5.5mm and 8.5 to 11.5mm. The end is a 0.5mm ball, to
help find calculus and ledges and to prevent passing into the gum tissues.

Question 37

Which probe should be used for a 6 point pocket chart?

Answer 37

The recommended probe is the UNC-15 probe, as it is easier and clearer to use.
The UNC-15 probe has millimetre intervals from 1mm to 15mm with black bands at 4-5mm, 9-10mm, 14-15mm.
The Williams probe has lines at millimetre intervals (123, 5, 789).
