Endodontics: Root Canal Assist · CDA

Why is the use of a rubber dam important during a root canal treatment?

  1. It improves visibility by actively retracting the surrounding soft tissue
  2. It isolates the tooth from saliva and bacterial contamination
  3. It helps administer anesthesia more effectively
  4. It delivers irrigation solutions into the canal
Show answer and explanation

Correct answer: It isolates the tooth from saliva and bacterial contamination

A rubber dam isolates the treated tooth, keeping the root canals free of saliva and oral bacteria, which reduces infection risk. It does not retract tissue or administer anesthesia.
