In operator safety, what’s the physics reason we stand at least 6 feet away and at 90–135 degrees from the primary beam during a 70 kVp intraoral exposure? I tell new assistants it’s scatter geometry plus the inverse square law — agree or add nuance?
On biopsies, we started handing out a mini card with a bold ‘saltwater rinse after 24 hrs, not 6’ plus our number; together with tension‑free closure (no overstuffed-suitcase sutures), our ‘is this normal?’ calls dropped, @DrMaya. If the site’s on movable mucosa, a dab of Orabase instead of an extra stitch keeps it comfy without tugging the margins.
