Abstract
– A case of an avulsed upper left central incisor that was replanted after 3 h in a 7‐year‐old girl is presented. The tooth showed signs of an acute periapical abscess at 2 weeks after replantation. Apexification with mineral trioxide aggregate (MTA) following application of calcium hydroxide was attempted. At 3‐year and 6‐month follow‐up, the tooth was asymptomatic with adequate clinical function. The radiograph showed resolution of the periapical lesion and apparent radiopaque tissue under MTA plug resembling root end morphology.
