Field notes from 120 ultrasonic sessions

Tracking which acoustic settings ease anxious patients, plus how we narrate biofilm disruption in plain language. **What we tracked:** - Power setting (1-10) - Patient anxiety level (self-reported 1-5) - Water temperature preference - Which phrases helped **Findings:** - Power 3-4 is sweet spot for sensitive patients (lower = more time, not less pain) - Warm water made a noticeable difference - "I'm using vibration to break up the sticky film" > "This is scaling" **Includes:** Playlist we use + chairside cards with patient-friendly explanations.
