ADC Practice Question — First Aid & PDL Cell Viability

Which replantation consideration applies?

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.

Four clinical scenarios: (A) A closed-apex tooth replanted at the scene — the dentist debates anesthetic choice. (B) An avulsed tooth in a child with severe uncontrolled epilepsy. (C) A tooth stored in tap water for 25 minutes. (D) An open-apex tooth showing radiographic signs of continued root formation 4 months post-replantation. Scenario B: the child has severe uncontrolled epilepsy. Which replantation consideration applies?

A. Replant normally — epilepsy has no bearing on the replantation decision in any circumstance
B. Replantation may not be indicated because severe cognitive impairment requiring sedation is listed
C. Replant but with a rigid splint for 6 weeks to prevent displacement during a potential seizure
D. The IADT does not address epilepsy — this falls outside the scope of dental trauma guidelines entirely

Correct answer: B

IADT: 'There are individual situations when replantation is not indicated (eg, an uncooperative patient, severe cognitive impairment requiring sedation, severe medical conditions).' Severe uncontrolled epilepsy may pose risks of aspiration or traumatic displacement of the replanted tooth. SOURCE — Fouad AF et al. IADT Avulsion Guidelines, Dent Traumatol 2020;36:331-342, Section 1

Remy's study tip — Trauma questions hinge on: tooth maturity (open vs closed apex), time out of mouth, storage medium, and fracture type.
