Regenerative endodontic treatment of an immature permanent canine-A case report of a 13-year follow-up

Data on long term survival and tooth stability after regenerative endodontic treatment are missing. The purpose of the present report is to describe regenerative endodontic treatment of a permanent mandibular canine with extensive coronal hypoplasia, immature root, and a periapical radiolucency. The regenerative endodontic treatment was initiated by irrigation of the root canal, followed by three weeks of triple antibiotic paste dressing and the creation of a blood clot scaffold covered with mineral trioxide aggregate. A one year clinical and radiographic follow-up demonstrated healing of the periapical radiolucency and the tooth remained stable and sound for almost thirteen years post treatment.
