BPE

The basic periodontal exam (BPE) is a screening tool used to identify if a periodontal tissue requires further examination.

A World Health Organisation (WHO) probe is used.

  • WHO Probe

Method

  • The dentition is divided into sextants
  • A WHO probe is ‘walked around’ the teeth in each sextant.
  • A score is assigned to each sextant based on the BPE scoring code – the highest score is used.
  • BPE Scoring Codes
    • 0 – pockets less than 3.5mm
      • No calculus/overhangs, no bleeding on probing
    • 1 – pockets less than 3.5mm
      • No calculus/overhangs, bleeding on probing
    • 2 – pockets less than 3.5mm
      • supra/subginigval calculus/overhangs
    • 3 – probing 3.5-5.5mm
    • 4 – probing >5.5mm
    • * – this symbol is added next to the BPE score to indicate ‘furcation involvement’
  • 3rd molars are not included unless 1st and/or 2nd molars are missing
  • For a sextant to qualify for recording, at least 2 teeth must be within the sextant

A BPE should be performed for all new patients. Sextants scoring 0, 1 or 2 should be re-scored at every exam. Scores of 3 or 4 indicate further investigation is required, such as more detailed periodontal charting.

Example of a BPE Score

For Code 3: perform 6point pocket chart and start with OHI and identify and control risk factors. Radiographs should be taken.
For Code 4: complete full 6point pocket chart for the whole dentition. Radiographs should be taken

6 point pockets charts(6ppc) should be taken pre and post perio therapy.
If a maintenance phase is achieved 6ppc should be performed annually.
BPE should not be used around implants – 6ppc is required here.
Bleeding on probing should supplement 6ppc’s

Treatment according to a sextants BPE score

  • 0 – No treatment indicated
  • 1 – OHI
  • 2 – OHI + sub/supragingival plaque removal
  • 3 – OHI + sub/supragingival plaque removal and RSD
  • 4 – OHI + RSD + consider specialist referral
  • * – Treat according to BPE score and consider specialist referral
