Should the root be soaked in topical doxycycline before replantation?
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.
Before replanting a 9-year-old's avulsed tooth, a colleague suggests soaking the root in doxycycline solution. Separately, the parent is unsure about the child's tetanus immunisation status. Should the root be soaked in topical doxycycline before replantation?
- A. Yes — topical doxycycline is the standard pre-replantation treatment for all avulsed teeth
- B. Yes — but only for open-apex teeth where revascularization is the primary treatment goal
- C. Yes — the guideline recommends a 5-minute soak in minocycline or doxycycline for all cases
- D. No specific recommendation can be made — human studies have failed to show improved outcomes

Therefore, a specific antibiotic, duration of use, or methods of application cannot be recommended based on human studies.' SOURCE — Fouad AF et al.
