Intentional replantation of endodontically treated second premolar with chronic apical abscess

Abstract

A case of 51-year-old female reported with pain of failed root canal treatment of the mandibular right second premolar. Periapical lesion, mobility, and deep periodontal pocket were detected during examination. Intentional replantation was discussed with the patient. The tooth was atraumatically extracted followed by root end resection and retrograde cavity preparation and filling with MTA. Curettage in conjunction with irrigation of the alveolus was considered to eliminate the inflammatory tissue. The tooth was replanted back into its socket and splinted to the adjacent tooth. The total extraoral treatment time was ≤15 min. One- and three-month follow-up revealed no clinical symptoms and progressive periapical healing. After 2 years and 7 months, complete periapical healing was evident. The success rate of intentional replantation is very promising when the procedural techniques are applied properly.
