Replantation of a maxillary second molar after removal of a third molar with a dentigerous cyst: Case report and 12-month follow-up

摘要

The aim of this study was to describe the replantation of a maxillary second right molar, which had been removedfor surgical reasons in order to remove a dentigerous cyst associated with the adjacent third molar, and the case's12-month follow-up.A 51-year-old man presented swelling in the right maxillary area. Radiographic examination showed a large radiolucencyin close proximity to the third molar, suggesting a follicular cyst. The third molar was extracted andthe cyst underwent curettage. The second molar had to be extracted to enable complete removal of the cyst and toachieve primary closure of the wound, which would have been impossible without repositioning the molar. Withthis objective, extraoral endodontic treatment was performed, the root-end was resected and prepared with ultrasonicretrotips, and root-end filling was accomplished with MTA before the molar was replanted. At the 12-monthfollow-up, the tooth showed no clinical signs or symptoms, probing depth was no greater than 3 mm and radiographicexamination showed no evidence of root resorption or periapical lesion.
