In this article, in laboratory conditions, the residual power of laser radiation after irradiation of the root of a remote incisor (tooth 1.1) of a person after his instrumental processing and obstruction of hot gutta-percha was studied. The channel of the removed incisor, in the upper third is sealed with hot gutta-percha, and in the middle and upper third it is not obstructed. The dependence of the effect on the residual power between the location of the laser emitter in the root canal (in the middle and wellhead) and the diameter of the roots of the extracted tooth was studied. A comparative analysis of the efficiency of the absorbed laser energy 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.
