Endodontics · single question

For a long-standing infected, non-restorable endodontically treated tooth, the best treatment is:

  1. Extraction
  2. Long-term CaOH2 dressing
  3. Surgical re-treatment (apicoectomy)
  4. Conventional re-treatment (orthograde)
Show answer and explanation

Correct answer: A. Extraction

  • A. Correct. For a non-restorable tooth with persistent infection, extraction is the treatment of choice. There is no purpose in retreating or performing surgery on a tooth that cannot be adequately restored afterward.
  • B. Long-term Ca(OH)2 dressing is a temporizing measure, not definitive treatment for a non-restorable tooth.
  • C. Surgical retreatment (apicoectomy) is reserved for cases where orthograde retreatment is not possible AND the tooth is restorable.
  • D. Re-treatment is appropriate for a tooth that IS restorable with remaining structure to support a crown.
