NaOCl is the most commonly used irrigant; however, its action does not affect inorganic materials. EDTA complements the response of sodium hypochlorite by chelating calcium ions in dentin and making instrumentation of the root canal easier.16 QMix has been found to be effective in removing the smear layer and also has substantial antimicrobial properties.7 Dai et al (2011)17 and Stojicic et al (2012)3 reported that QMix was as effective as 17% EDTA in smear layer removal. This was based on the number of fully opened dentinal tubules.
