Cyst #15 (4)
The patient is a healthy, 46-year-old female. In the area of tooth #15 (4) there was an inflammatory lesion that presented with pain and another clinical symptoms. The tooth had a prosthetic restoration with a crown and was blocked with another crown on tooth #14 (5).
It was decided to perform an apicoectomy of tooth #15 (4). One-step microsurgery was done with radicular cyst removal (with histopathology), root resection of #15 (4) with retrograde MTA filling (two canals). The bone defect was filled with Bond ApatiteŽ (1 cc). By the operation both cortical laminas were destroyed, the buccal after making the trepanation hole and from the sinus site because of a cyst with reactive inflammatory changes in sinus.
The patient reported medium pain and discomfort in the first two days after surgery. Good healing and bone remodeling were observed during the 4 years of follow up, without any inflammation. The patient reported no clinical symptoms. The cortical lamina from sinus site was reconstructed after 4 months. CBCT after 4 years confirmed good healing of the bone and stability of regenerated cortical both laminas.
