Replantation of an immature mandibular primary central incisor after avulsion: A case report

The favorable conditions for revascularization of replanted immature primary teeth after avulsion are not well understood. We report a case of replantation of an avulsed immature mandibular primary central incisor in a 7-month-old male infant. The avulsed incisor was replanted and fixed. Five months later, root canal obliteration was observed. The replanted incisor showed root formation a year later without negative symptoms and was replaced by its successor after 6 years. Based on the outcomes, the clinical course of revascularization after replantation and treatment protocol of avulsed immature primary teeth might be comparable to those of immature permanent teeth.
