Sample item

What is the main goal of root canal treatment?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Remove infected pulp tissue and seal the canal system

Root canal treatment removes inflamed or infected pulp, disinfects and shapes the canal system, then fills it to reduce reinfection and retain a tooth that would otherwise be at risk of persistent pain or abscess.

Option by option

  • A. Strengthen jaw muscles

    Jaw strengthening is not the purpose of root canal therapy.

  • B. Remove infected pulp tissue and seal the canal system (correct)

    Correct: endodontic treatment removes infection and seals root canals.

  • C. Whiten enamel using fluoride

    Fluoride supports enamel prevention but does not treat infected pulp.

  • D. Replace a missing tooth with a denture

    Dentures replace missing teeth rather than treating a retained infected tooth.
