[The surgical treatment of periradicular cysts of the jaws].

The author has succeeded in improving functional results of surgical treatment of the teeth that caused pararadical cysts. This was due to access to the pathologic focus, preservation of the 'causative' tooth root, filling of the residual osseous cavity with formalin-treated allogenic placental transplant. A total of 79 patients were operated on using this method. Late results were followed up for 2 years, no recurrences occurred and functional status of the operated on 'causative' teeth permitted their use as abutment teeth for bridge dentures.
