Treatment of an apical cyst with platelet concentrate – a case report

Apical cysts are typically caused by dental pulp disease and are difficult to treat. In the majority of cases, surgical intervention is required. The rate of success after apical osteotomy varies between 60% and 91%. The introduction of platelet concentrates in treating chronic apical periodontitis is a promising direction for achieving quick and secure results. This article examines the healing of a sizable apical cyst after conservative surgical intervention and the application of platelet concentrate. We present the case of a patient with a large apical cyst (0.799 cm3) of teeth 24 and 25 which was treated in this study. The precise endodontic treatment was performed with regenerative components such as gaseous ozone and EDTA irrigation. Apical osteotomy was performed, followed by inserting advanced platelet-rich fibrin plus (A-PRF+) into the surgical wound. Nine months after treatment, the bones of teeth 24 and 25 were fully healed without any changes to the sinus and nine months after surgically removing the radicular cyst, rapid and complete tissue repair was demonstrated
