All of the following should be done when placing a rubber dam EXCEPT:
Show answer and explanation
Correct answer: B. Floss interproximal areas AFTER the rubber dam is placed
B) Flossing AFTER placement — CORRECT (this is NOT the standard step).
The correct rubber dam protocol includes: (1) examine and floss interproximal contacts BEFORE placement to ensure the dam can pass through; (2) punch holes, place clamp, and apply dam; (3) tuck the dam into the sulci. Flossing interproximal areas AFTER placement (through the dam) is not a standard step — the dam itself is passed through contacts using floss to seat it, but flossing the contacts after full placement is not routine.
A) Flossing before: Essential — ensures the dam can be seated through tight contacts.
C) Quadrant isolation: Appropriate for endodontic or restorative procedures.
D) Securing the clamp: Critical safety step before beginning to prevent aspiration.
