Dentistry · Dental trauma: avulsion

Sample item

A permanent incisor is avulsed during sport and is visibly dirty. What is the best immediate handling advice if reimplantation is feasible?

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

The answer and the reasoning

C. Handle by the crown, gently rinse, and reimplant or store in suitable medium promptly

For an avulsed permanent tooth, periodontal ligament cells should be protected: handle the crown, avoid scraping the root, rinse briefly if needed, and reimplant promptly or store in a suitable medium while seeking urgent dental care.

Option by option

  • A. Scrub the root vigorously and leave it dry

    Scrubbing and drying destroy root surface cells needed for healing.

  • B. Discard the tooth because reimplantation is never indicated

    Permanent teeth may be replanted; primary teeth are generally not replanted.

  • C. Handle by the crown, gently rinse, and reimplant or store in suitable medium promptly (correct)

    Correct. This minimizes damage to viable periodontal ligament cells.

  • D. Store it in concentrated alcohol

    Alcohol damages periodontal ligament cells.
