Aim:
To evaluate if endodontic and fluoride treatment of the root before delayed replantation would render the tooth a favorable prognosis.
Methods:
A 10-year-old boy reported 10 hours after he had avulsed his maxillary right permanent central incisor. The pulp and PDL cells were considered to be nonviable. Endodontic treatment for the tooth was performed extraorally and obturated with gutta-percha. Prior to replantation, the root was treated with 1.23% APSF for 15 minutes.
Result:
An intraoral radiograph taken 6 months after replantation revealed narrowing of the PDL space around the replanted tooth due to apposition from the surrounding alveolar bone. A radiograph taken 5 years after replantation revealed no evidence of external root resorption. There was no abnormal mobility either.
Conclusion:
Extraoral endodontic treatment and root treatment with 1.23% APSF prior to delayed replantation might prevent the occurrence of external root resorption.
