Purpose of research. Assessment of informational content of x-ray method of research of root canal resorption, allowing an accurate evaluation of the localization, the size of the process and to plan the treatment CBCT. Materials and methods. The present study was approved by local ethic commettee Sechenov University 19.04.2017 N 03-17. The patient signed a form of informed consent and gave written permission for the processing of personal information and publication of pictures. The material for the study was the literature publications mainly in the last ten years: x-ray signs that are observed in various types of resorption, as well as their own x-ray materials in the examination of patients with the diagnosis: external cervical resorption of the tooth 13 (K 03.3). To confirm the diagnosis, CBCT was performed, with the help of which it was possible to make accurate diagnoses, estimate the volume of the resorbed area and plan the treatment of root resorption. Results. Treatment of root resorption after CBCT was performed in the following sequence: 1. Endodontic treatment with subsequent filling resorption section and the outer access. 2. Pulp extirpation, mechanical and medical treatment of the canal. 3. The crown part is restored with Enamel filling material. 4. Treatment was complicated by the position of the focus on the border of the Palatine and distal surface of the root. The surgeon-dentist was thrown Muco-periosteal flap. With the help of an operating microscope, the resorption site was visualized and cleaned with carbide spherical boron No. 3, then the resorbed cavity was further treated with a solution of trichloroacetic acid 40%. The defect is closed, the MTA and the Wound sutured. Summary: 1. Tooth root resorption is a poorly understood pathological process, which not sufficiently described in the literature; the timely diagnosis of it may be a problem in practical dentistry. 2. Different types of resorption may look different on x-rays. It is necessary to carefully examine the patient before making a diagnosis and planning the treatment of a tooth with internal root resorption. 3. At present, CBCT is the most objective diagnostic method within root resorption, allowing to accurately assess the location, size of the process and plan the treatment. 4. Despite the large amount of root defect, timely treatment provides a good long-term prognosis for teeth affected by cervical resorption. Key words: resorption of tooth tissues; etiological factors; radiological methods of diagnostics of resorption of tooth tissues; cone - beam computed tomography in the diagnosis of resorption of tooth tissues; treatment of resorption.
