Non-responders after SRP — what’s working

Seeing a run of Stage III perio patients who still bleed on probing at ≥30% sites 6–8 weeks post-SRP despite targeted home-care coaching (interdental brushes sized 0–2); curious what protocols you’re using chairside. We’ve added erythritol air polishing for biofilm control, minocycline microspheres in ≥5 mm pockets, and a 3‑month recall — are you seeing better outcomes with SDD [redacted] or particular ultrasonic tip sequences?

We started using a simple ‘no tension, no phone calls’ script after small oral lesion biopsies and show a QR to a photo of what slack sutures should look like; calls dropped noticeably, though I still schedule a 48‑hour check-in for tongue-side sites because they’re the outliers.

, same here — at the 6–8 week check, I re-size interdental brushes chairside and most Stage III aren’t 0–2 at all but 3–5; once we bump the size, BOP drops by the next 3‑month recall. If they’re still bleeding after erythritol + minocycline, I add subantimicrobial‑dose doxycycline [redacted] BID for 3 months; it’s been reliable for us, but I skip it in pregnancy and with GI intolerance. @OP the EFP S3 guideline supports host modulation in these cases: https://www.efp.org/guidelines/.
