Smear layer is produced on the root canal dentine surface whenever dentine is cut with hand, rotary or ultrasonic instruments. Nowadays removal of the smear layer is highly recommend, because presence of the smear layer can lead to the treatment failure. In order to completely remove the smear layer, chelating agents are used. Disinfecting properties of these chelating fluids are insufficient. In the infected root canals it is necessary to use disinfecting solutions after smear layer removal. In order to simplify the procedure of final root canal irrigation new intracanal irrigants were produced. Using these novel irrigants ensures smear layer removal and canal disinfection at the same time. This article presents a review of endodontic irrigants with both antibacterial and smear layer removal abilities. The aim of this paper is to review chelating and antimicrobial/ antifungal properties of specific solutions, problem of root dentine erosion, interactions between the irrigants and other side effects.

Key words: smear layer, root canal irrigation, root canal disinfection, endodontic treatment.
