Use of peracetic acid as irrigating agent in endodontics

The irrigation of the root canal system contributes effectivelyto appropriate cleanness and antisepsis, thusrendering endodontic treatment more successful. Anideal irrigation protocol was suggested in order to overcomethe limitations of commonly used irrigants, inaddition to enhancing antisepsis. This protocol recommendsthe use of sodium hypochlorite during biomechanicalpreparation, followed by the use of a chelatingagent, and again the use of an agent with antimicrobialaction. However, it demands considerable clinical time.An alternative to reducing that time would be the useof a final irrigating agent contemplating both chelatingand antimicrobial actions. Thus, it has been suggestedthat peracetic acid (PAA) be used as a substitute forEDTA for final irrigation, since this substance has showngood antimicrobial potential associated with chelatingcapacity. Some studies have been conducted in orderto analyze the effectiveness of its use as an irrigatingsolution in Endodontics. This literature review aims topresent to clinicians and specialists in Endodontics theproperties of this irrigating solution by providing relevantinformation on its effectiveness and feasibility inthe endodontic practice.
