Abstract

Objective: comparison in vitro of the effectiveness of various irrigation techniques of the root canal system in the process of instrumental preparetion using scanning
electron microscopy.
Object and methods. The study of various methods of irrigation was carried out on 7 permanent teeth, extracted according to various indications with the written
consent of patients, age 35–40.
Results. The use of cotton points or insulin syringe for irrigation purposes is not feasible, since most of the debris remains on the walls of the spacecraft. Significantly
better results can be achieved with the help of a standard endodontic needle with a safe tip, but qualitative cleaning was only achieved in the orifice of the
third, on the apex, the number of debris increased significantly. When irrigation with a needle with a brush, only a small amount of scattered debris was observed on
the walls of the spacecraft. The best result was achieved with irrigation with simultaneous activation by sound or ultrasonic method.
Comparison of the quality of cleaning of different areas of root canals showed that the applied methods of irrigation can cleanse the mouth and middle third, unlike
apical. This can be explained by the complex anatomical structure and the impossibility of «delivering» an irrigation solution to the apical third of the root using most
of the proposed methods of irrigation.
Conclusions. The use, during endodontic treatment, of additional methods of activation significantly increases the diffusion of intracanal antiseptics, their hydrolytic
and antibacterial effectiveness, which improves the adhesion of sealants. And most importantly, it significantly reduces the risk of complications and allows you to
achieve a long-lasting successful clinical outcome.
Key words: root canal system, irrigation techniques, debris, scanning electron microscopy.
