removing the splint, the tooth is mobile. What does…
Dental trauma questions test protocol-level decisions — splint type, duration, follow-up timing — where one wrong detail means a wrong answer. This exam-level vignette tests your ability to work through clinical details and arrive at the correct management.
A replanted incisor has been splinted for 2 weeks. At the splint removal appointment, the dentist checks the tooth's stability. The tooth shows some mobility and the patient reports mild discomfort when biting. After removing the splint, the tooth is mobile. What does the IADT recommend?
- A. Re-splint immediately for an additional 4 weeks using a rigid splint to ensure full PDL healing
- B. Extract the tooth immediately — any residual mobility at the 2-week mark indicates failed periodontal healing overall
- C. No additional intervention — some mobility after splint removal is expected and should be monitored
- D. An additional week of splinting is appropriate ONLY if opposing dentition trauma or positioning issues exist

IADT: 'The patient and parent should be advised that on removal of the splint, the injured tooth may be mobile. An additional week of splinting is appropriate only if excessive trauma from the opposing dentition might further traumatize the tooth or if the avulsed tooth is unable to remain in the correct position.'
