The irrigation of the root canal system contributes effectively to appropriate cleanness and antisepsis, thus rendering endodontic treatment more successful. An ideal irrigation protocol was suggested in order to overcome the limitations of commonly used irrigants, in addition to enhancing antisepsis. This protocol recommends the use of sodium hypochlorite during biomechanical preparation, followed by the use of a chelating agent, and again the use of an agent with antimicrobial action. However, it demands considerable clinical time. An alternative to reducing that time would be the use of a final irrigating agent contemplating both chelating and antimicrobial actions. Thus, it has been suggested that peracetic acid (PAA) be used as a substitute for EDTA for final irrigation, since this substance has shown good antimicrobial potential associated with chelating capacity. Some studies have been conducted in order to analyze the effectiveness of its use as an irrigating solution in Endodontics. This literature review aims to present to clinicians and specialists in Endodontics the properties of this irrigating solution by providing relevant information on its effectiveness and feasibility in the endodontic practice.
