Pharmacology · single question

A permanent tooth has been avulsed and is being replanted. Regarding systemic antibiotics, the current recommendation is to:

  1. Never prescribe antibiotics
  2. Prescribe systemic antibiotics (e.g., doxycycline or amoxicillin) as an adjunct to replantation
  3. Prescribe antibiotics only if it is a primary tooth
  4. Prescribe antifungals instead
Show answer and explanation

Correct answer: B. Prescribe systemic antibiotics (e.g., doxycycline or amoxicillin) as an adjunct to replantation

IADT guidelines recommend systemic antibiotics as an adjunct after replantation of an avulsed permanent tooth to reduce infection-related inflammatory root resorption; tetanus status should also be checked.Other options: Antibiotics are indicated (not never); avulsed primary teeth are not replanted; antifungals are not indicated.Key exam takeaway: Replanted permanent avulsed teeth get systemic antibiotics plus a tetanus check and flexible splinting.
