In this article, the residual power of laser radiation after irradiation of the root system of the remote human incisor with a part of the endodontic instrument in the upper third was studied in the laboratory. The dependence of the influence on the residual power of the location of the laser emitter in the root canals (in the tool area, 1 mm from it, in the middle part of the channel and in the mouth) and the diameter of the roots was studied. A comparative analysis of the efficiency of laser irradiation of the root canals of two high-intensity diode laser systems of the near infrared spectrum with wavelengths of 810 and 980 Nm is carried out.

Keywords:laser system, residual power, root canal of the tooth.
