Electrolyzed water (EW) has been introduced as a surface disinfectant due to its antimicrobial properties without cytotoxic effects to oral tissues contrary to sodium hypochlorite (NaOCl), which is cytotoxic and can be detrimental if extruded beyond the root canal. This scoping review aimed to compare antimicrobial efficacy of EW with NaOCl on root canal pathogens and to assess effect of concentration and exposure time on antimicrobial efficacy. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews protocol guidelines. Electronic databases were searched for eligible articles published between 2011-2021 in PubMed, PLOS, Science Direct, and Google Scholar. Joanna Briggs Institute Critical Appraisal Tool was used for quality assessment. Of the 784 articles recovered, only 8 were eligible based on inclusion criteria. The included studies assessed several types of EW, which showed antimicrobial potential against E. faecalis in vitro in suspension and biofilm forms. EW demonstrated antimicrobial efficacy comparable with NaOCl in 5 of 8 studies. Only one study found that higher concentration and exposure time increased antimicrobial efficacy of EW; other studies showed otherwise. It can be concluded that EW can be a potential alternative solution for NaOCl as an endodontic irrigant.
