It was assumed that the additional use of ethylenediaminetetraacetate (EDTA) and passive ultrasonic irrigation (PUI) would result in an increased rate of absence of symptoms and remission based on the periapical index (PAI) compared to passive irrigation using only sodium hypochlorite (NaOCl) %K Disinfection %K Endodontic therapy %K Passive ultrasonic irrigation %K Root canal %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4988088/
