Electrochemically activated (ECA) water has been found to be biocompatible and effective in wound cleansing . Two types of ECA solutions can be produced from tap
water and a saline solution using a flow-through electrolytic module . The first is an anolyte that has antimicrobial properties, a high oxidation potential, and a pH value
ranging from 2 to 9. The other is a catholyte that acts like a detergent, has a high reduction potential, and is alkaline. Electrochemically activated water exists in a metastable state that contains a variety of free radicals, molecules, and ions. Biocidal agents, such as hydrogen peroxide, sodium hydroxide, and ozone, are also present in ECA water. After 48 hours, the solution will return to a stable inactive state. Electrochemically activated water is more effective than sodium hypochlorite solution in smear layer removal. Nevertheless, when the anolyte and catholyte were used individually to irrigate infected root canals, results of antimicrobial effectiveness tests were disappointing compared with 3.5% sodium hypochlorite.
