Since primary endodontic treatment is most often performed by clinicians in the case of endo-periodontal lesions, the choice of endodontic instrument should be based on a bioequivalent approach: minimally invasive mechanical treatment of the root canal with maximum preservation of the anatomical shape of the root canal. Subject. The subject of the study is the choice of the optimal system for machine treatment of root canals in endo-periodontal lesions. Objectives. To compare morphostructural changes in the surface of dentin of tooth roots under the influence of different machine endodontic instruments in patients with endo-periodontal lesions. Methodology. The material for the experimental study was samples of freshly extracted teeth - incisors of type I according to Vertucci (36 samples) of a patient living in the Ural region, who had indications for tooth extraction due to severe chronic generalized periodontitis. The study of samples was carried out using a scanning electron microscope JSM-6390LV from Jeol. Results. The samples treated with the Reciproc (8% apical taper) and WaveOne (7% apical taper) systems underwent the most aggressive treatment and thinning of the root canal walls. After using the RusMed M-files (4% apical taper) and ProTaper (6% apical taper) systems, the anatomy of the root canals was maximally preserved. Conclusion. A comparison of morphostructural changes in the dentin surface of tooth roots under the influence of different machine endodontic instruments in patients with endo-periodontal lesions was carried out. The best results were obtained when using rotary systems with instrument tapers of 4 and 6, which was confirmed by scanning electron microscopy.
