Given these findings, should endodontic treatment be initiated?
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.
An 8-year-old's open-apex upper left central incisor was replanted 3 weeks ago. At follow-up, the dentist notes the tooth is asymptomatic, has normal mobility, and radiographs show no periapical radiolucency. The root canal appears slightly narrower than at the baseline radiograph. Given these findings, should endodontic treatment be initiated?
- A. Yes — all replanted teeth require root canal treatment within 2 weeks regardless of apex status
- B. Yes — canal obliteration will make future endodontic access impossible, so treat preventively now
- C. No — continued root development and canal obliteration indicate successful revascularization
- D. No — but only because the child is too young for root canal treatment at age 8
