Popis: The quality of endodontic treatment largely depends on the mechanical cleaning of the root canal, which is carried out in most cases by machine nickel-titanium instruments. Despite their great diversity, there is no universal system that is simple and effective, allowing you to work in the root canal with complex anatomy. Therefore, new tools are being created.Aim. Compare the effectiveness of root canal treatment with three different systems (Reciproc Blue, Mtwo-tile and Soco SC Pro). Perform an analysis of the results using scanning electronic microscopy, assess the quality of mechanical cleaning of the root canal when using these tools.Materials and methods. The study used 30 extracted teeth (with root curvature greater than 25 degrees), divided into 3 groups (10 in each group). In group 1, mechanical processing was performed using Reciproc Blue. The second group used Soco SC Pro system tiles, and the third control group used the Mtwo-tile. Then, thin sections were made and the results evaluated using an electronic scanning microscope.Results. According to the results of scanning electronic microscopy of 15 sections in each group, it was revealed that the maximum number of open dentinal tubes is observed working with Reciproc Blue in 60% of cases, while Soco SC Pro - in 27% of cases and Mtwo-file - in 40%. Based on this study, it can be concluded that the Reciproc Blue system has the best cleaning mechanical ability.As a result, it was found that the time spent working with nickel- titanium tools subjected to heat treatment (Reciproc Blue, Soco SC PRO) is less than when working with Mtwo-fiie.Conclusions. 1. Scanning electronic microscopy studies have shown that the quality of mechanical cleaning when processing the root canal of Reciproc Blue and Mtwo-file is higher compared to Soco SC Pro. 2. The time taken to process the root canal with Reciproc Blue tools is less than when working with Soco SC Pro and Mtwo-fiie. S.Nickel- titanium instruments from M-Wire alloy (Reciproc Blue and Soco SC Pro) allow machining in curved root canals with preservation of their anatomy and the time spent processing the root canal with Reciproc Blue and Soco SC Pro tools is less than with Mtwo-fiie.
