title: Antibacterial Efficacy of Super-Oxidized Water onEnterococcus faecalisBiofilms in Root Canal.
abstract: BACKGROUND
  The success of endodontic treatment depends on a few crucial factors. One of these factors is the complete chemomechanic preparation of root canal against various bacteria. In particular, the effect of resistant bacteria may cause intense pain with flare-up and formation of periapical lesions. Therefore, the strong effect of irrigants plays an important role in terms of the complete elimination of these bacteria to achieve long-term successful treatment.
  
  
  OBJECTIVE
  The aim of this study was to investigate the antibacterial effects of super-oxidized water (SPO) in root canals infected withEnterococcus faecalisbiofilms.
  
  
  METHODS
  One hundred twenty single-root, premolar teeth were selected. Initially, the teeth were prepared and then disinfected.E. faecaliswere inoculated and kept at 37°C for 24 hours in the root canals. The re-inoculation procedure was repeated on the first, fourth, seventh, and tenth days. The infected root canals were divided into one negative (saline) and one positive (sodium hypochlorite) control group and four experimental groups (super-oxidized water: 1, 2, 3, or 5 minutes) (n = 20). Paper points were placed in the root canals to control and evaluate the biofilm formation. Biofilms were counted on blood agar plates, and data was evaluated and statistically analyzed using one-way ANOVA and Tukey's test.
  
  
  RESULTS
  Although sodium hypochlorite (NaOCl) showed no statistically significant difference when compared with three and five minutes of SPO irrigation (P > 0.05), NaOCl showed statistically significant differences among all other groups (P < 0.05).
  
  
  CONCLUSIONS
  Super-oxidized water indicated a remarkable and similar bactericidal effect to that of traditional NaOCl againstE. faecalisbiofilms. In terms of successful endodontic treatment approaches, super-oxidized water may be used as an effective irrigation solution in clinics.
