What is the treatment for a horizontal root fracture located in the cervical third?

  1. Splint for 4 months and monitor
  2. No treatment — these heal spontaneously
  3. Extraction, with implant or other replacement planned
  4. Root canal treatment of the apical fragment only
Show answer and explanation

Correct answer: C. Extraction, with implant or other replacement planned

  • A. Splinting is the treatment for middle- and apical-third fractures, which have far better prognoses.
  • B. Apical-third fractures often heal favorably; cervical-third fractures do not.
  • C. Correct. Cervical-third fractures carry the worst prognosis. The coronal fragment lacks bony support and the fracture line communicates with the sulcus, allowing bacterial contamination — extraction and replacement is generally indicated.
  • D. Endodontic treatment does not restore support to an unsupported coronal fragment.
