Aim. To determine the antibacterial efficiency of heat treatment on teeth root canals by the application of laser radiation and high-frequency diathermocoagulation in the complex curative measures. Materials and methods. We conducted 120 experiments on the removed teeth that were first placed for 24 hours in natrium chloride isotonic solution. Depending on the type of influence being studied, remote teeth were up-diffused in three groups. The antibacterial action of the high-energy laser radiation and high-frequency diathermocoagulation were studied. Results. During the experiment, the high antibacterial effect of monoarctic diathermocoagulation was reduced with the use of alternating current at a frequency of 2,64 Mhz in the treatment of the teeth root canals. Conclusion. The use of diathermocoagulation increases the effectiveness of the treatment measures, which helps to reduce the number of complications and the need for repeated interventions in the treatment of dental caries complications.
