What is the best treatment for tooth #5 with a horizontal root fracture in the middle third and a non-restorable/mobile coronal segment?

  1. Extraction (with implant planning) when the fracture renders the tooth non-restorable
  2. Routine root canal therapy alone
  3. Direct composite restoration
  4. No treatment
Show answer and explanation

Correct answer: A. Extraction (with implant planning) when the fracture renders the tooth non-restorable

Mid-root and especially cervical-third horizontal fractures with a mobile coronal segment carry a poor prognosis; extraction (with implant replacement) is usually indicated. (Apical-third fractures may sometimes be monitored or splinted.)Other options: Root canal alone or a composite does not stabilize an unfavorable mid-root fracture; doing nothing leaves a symptomatic non-restorable tooth.Key exam takeaway: Mid-/cervical-third root fractures with a mobile segment usually require extraction and implant; apical-third fractures may be monitored.
