Correct answer: B — 2 weeks
Per IADT 2020 guidelines, a replanted avulsed permanent tooth should be splinted with a flexible (passive, non-rigid) splint for 2 weeks. The flexible splint allows physiological movement, promoting PDL healing and reducing the risk of ankylosis/replacement resorption. The splint wire (0.4 mm stainless steel or nylon) is bonded to the labial surfaces of the replanted tooth and adjacent teeth with composite resin. Root canal treatment should be initiated 7-10 days after replantation for closed apex teeth.
