The reason for the development of odontogenic radicular cyst in 40% is complicated tooth caries. In 60% the cyst occurs as a complication of endodontic treatment: extrusion of the necrotic pulp to the top of the tooth with and the subsequent development of periodontitis, injury to the pulp in odonto preparation, especially with anesthesia. Radiological methods are very important during the treatment planning and monitoring of bone tissue regeneration after surgery in the jaws root cysts.

Purpose. To determine the role of microfocus x-ray at an intraoperative phase of surgical treatment of jaws root cysts with the help of Er:YAG and Nd:YAG lasers. Materials and methods. A total of 59 patients with differently localized radicular cysts underwent surgical treatment, including cysts of the mandible in 15 patients, upper jaw – in 44 patients. There were 32 women and 27 men. The patient’s age ranged from 21 to 62 years. The technique of combined application of Er:YAG and Nd:YAG lasers have been used in patients, in 12 of them – with the help of xenogenic osteoplastic material. For the diagnosis and evaluation of reparative processes in the bone tissue portable digital micro-focus x-ray diagnostic complex "Pardus-Stoma" (Russia) was used. Results. During the surgical intervention the bone defect was determined using digi-tal microfocus radiography, it’s relation to the anatomical structures, identification of small and low contrast details (residual filling material, free bone fragments), and the status of the resected root apex. In patients with xenogenic osteoplastic material microfocus x-ray allowed us to assess how smoothly and completely the bone defect was filled with osteoplastic mate-rial. Conclusions. Microfocus radiography is the method of choice for intraoperative mon-itoring and in the postoperative period for evaluation of the reparative processes of bone tis-sue in patients after cystectomy, cystotomy. In the postoperative period the use of microfocus x-ray allows us to study the process of osteoregeneration in postoperative bone defect on different stages of rehabilitation.
