Report of C a s e A 9-year-old girl was seen in the pediatric dental clinic for extraction of her mandibular right second primary molar. During extraction, the incompletely formed and unerupted mandibular right second premolar was accidentally removed from its developmental crypt by a dental student. The faculty member in charge rinsed the tooth (solution unknown) and replanted the tooth within an elapsed time estimated at less than two minutes. Records available on the patient are incomplete, with no significant clinical information other than radiographs taken at one week (Fig 1), five years (Fig 2), and six years (Fig 3) after replantation. These radiographs show that root formation continued and that calcific metamorphosis occurred.
