Endodontics · single question
A mature permanent incisor is severely intruded into the socket after trauma. Which management approach is appropriate?
Show answer and explanation
Correct answer: A. Reposition (orthodontically or surgically) and plan endodontic therapy, because pulp necrosis is very likely
Intrusion carries the highest risk of pulp necrosis and root resorption. Immature teeth may re-erupt spontaneously, but mature or severely intruded teeth require active repositioning and typically endodontic treatment (often with calcium hydroxide) to prevent inflammatory resorption; close follow-up is essential.Other options: Adults' severely intruded mature teeth usually do not re-erupt adequately; routine extraction is not first-line; monitoring is required.Key exam takeaway: Intrusion has the worst prognosis; reposition and expect root canal therapy in mature teeth, while immature teeth may re-erupt.
