Abstract: Canal irrigation during root canal treatment is an important component of chemo-mechanical debridement of the root canal system. Traditional syringe irrigation can be enhanced by activating the irrigant to provide superior cleaning properties. This activation can be achieved by simple modifications in current technique or by contemporary automated devices. Novel techniques are also being developed, such as the Self-adjusting File (Re-Dent-Nova, Ra’anana, Israel), Ozone (Healozone, Dental Ozone, London, UK), Photo-activated Disinfection and Ultraviolet Light Disinfection. This paper reviews the techniques available to enhance traditional syringe irrigation, contemporary irrigation devices and novel techniques, citing their evidence base, advantages and disadvantages.

Clinical relevance: Recent advances in irrigation techniques and canal disinfection and debridement are relevant to practitioners carrying out root canal treatment.

Objective: To understand the clinical methods available for achieving superior disinfection and debridement of the root canal, either by enhancing traditional syringe irrigation techniques or by considering novel strategies.
