Question 252 · LDEK · Trauma to permanent teeth
In the case of an avulsed tooth with an open apex, which was kept outside the mouth in saline for less than 60 minutes, one should:
1) immerse the tooth in a minocycline solution for 5 minutes;
2) immerse the tooth in a 2% solution of sodium fluoride for 20 minutes;
3) immobilize the tooth for a period of 2 weeks with elastic splint;
4) immobilize the tooth for a period of 4 weeks with elastic splint;
5) perform the root canal treatment after 7 days since the replantation.
The correct answer is:
2) immerse the tooth in a 2% solution of sodium fluoride for 20 minutes;
3) immobilize the tooth for a period of 2 weeks with elastic splint;
4) immobilize the tooth for a period of 4 weeks with elastic splint;
5) perform the root canal treatment after 7 days since the replantation.

Hint
For an open-apex tooth replanted after short wet storage the goal is pulp revascularization; consider splint time and whether early root canal therapy fits.
