Irrigation is the key step in disinfection of the root canal system. Reducing the bacterial load within the apical 3mm of the canal in preparation for obturation is largely achieved with chemo-mechanical debridement utilising files and hypochlorite. The method with which the irrigation is applied has come under a lot of focus recently with various adjunctive instruments utilised to improve agitation of the hypochlorite.

The below paper co-authored with Richard Holliday looks at these different methods and summarises why the type and the delivery of irrigant to the root canal system is so important.
