Antibacterial efficacy of various methods of heat treatment of root canals

Abstract

Purpose. Study of the antibacterial efficacy of various types of laser radiation and high-frequency diathermocoagulation during endodontic treatment of the root canals of the teeth. Materials and methods. Conducted 90 experiments on the removed teeth. Before the study, the extracted teeth were kept in isotonic sodium chloride solution for 24 hours. Depending on the type of impact studied, the extracted teeth were divided into three groups. The antibacterial effect of two types of high-energy laser radiation and highfrequency diathermocoagulation was investigated. Results. A high antibacterial efficacy of monopolar diathermocoagulation was detected using an alternating current frequency of 2.64 MHz when treating the root canals of the teeth. Conclusions. With increasing power, the antibacterial effect of diathermocoagulation increases.
