# PERIODONTAL TIP

### Bleeding on Probing

When we are doing a re-assessment of periodontal conditions following an active phase of non-surgical periodontal therapy (i.e. supra/sub-gingival debridement), we probe a sulcus/pocket to evaluate the probing depth, but also the Bleeding on Probing (BoP).

…these are my tips…

1. If bleeding is noted after probing (BoP +), it means not only that the examined site is inflamed, but also that there is a 30% of probability that gingivitis is progressing into periodontitis.

Therefore…periodontal disease is not stable at that site!

2. If you are probing a pocket > 5 mm and there is no bleeding after probing (BoP –), there is a 98% of probability of absence of further clinical attachment loss.

Therefore…your pocket is not getting worse!

###### From the above 2 tips, you can realize how important is the assessment of bleeding on probing (and not only the pocket depth!) for your future clinical decisions and treatment planning.
