Reimplantation of primary tooth--case report

This article reports a clinical case of a primary tooth avulsion followed by dental reimplantation and endodontic treatment according to the protocol established by the Federal University of Santa Catarina for the treatment of traumatized primary teeth. A patient, 2 years and 6 months of age, MR, suffered the avulsion of tooth 61 because of a fall at school. The child was given dental assistance within 30 min, and the avulsed tooth was stored in milk during the period. After radiographic examination, the tooth was reimplanted and splinted. This procedure was performed after having obtained the mother's permission. Endodontic treatment was implemented a few days after the reimplantation because of the pulp necrosis that originated from a neurovascular bundle rupture. The endodontic treatment consisted of calcium hydroxide manipulated using glycol propylene dressings. After 12 months of treatment, the avulsed tooth presented the absence of periapical bone rarefaction in addition to a dry root canal, presenting ideal conditions for a definitive obturation. The obturation was applied using ZOE. The follow-up procedures on the obturated tooth were performed until the total eruption of the succeeding permanent tooth had been achieved, with no sequelae. Reimplantation, followed by endodontic treatment performed according to biological principles, has proven to be a good option for avulsed primary teeth.
