The patient is a healthy Female, age 34 years. The little cyst was grown after endo treatment of #36 (19) and prosthetic restoration. A broken piece of endo tool was left in the mesial root. The patient experienced some pain and discomfort when biting certain things, such as hard food.
Root resection was performed on both roots of tooth #36 (19), with cyst enucleation (including a histopathology examination) and back fill of all the root canals with MTA. The bone defect was filled with Bond Apatite® (1 cc).
Two-year follow-up showed good growing of the new bone. No pain and inflammatory symptoms were noted.
