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 10-year-old's replanted incisor has become ankylosed 18 months after replantation. The tooth is now 3mm infra-positioned compared to the adjacent incisors and the discrepancy is worsening as the child grows. When should the decision to decoronate an ankylosed replanted tooth be made?
- A. Immediately upon initial diagnosis of ankylosis, before any measurable infra-position develops at all
- B. Only after growth is completed, when the final degree of infra-occlusion can be assessed
- C. When the infra-occlusion is esthetically unacceptable and cannot be corrected by simple restorative means
- D. Decoronation should never be performed — extraction and immediate implant placement is preferred
