Study on the effects of electrolyzed oxidizing water in root canal treatment / 实用口腔医学杂志

ABSTRACT

Objective: To clinically evaluate the efficacy of electrolyzed oxidizing water (EOW) as a root canal irrigation solution on disinfecting bacteria and removing the smear-layer to keep the non-bacterium state in the root canal. Methods: In the first experiment, 108 single-rooted teeth that needed root canal treatment were randomly divided into two groups. EOW was used as the root canal irrigation solution in the experimental group while 30 ml/L H2O2, saline solution, and 75 g/L EDTA solution were used as controls. Bacteriological examinations were conducted from each tooth before and after treatment with the root canal irrigation solutions. In the second experiment, the 20 fresh human extracted teeth were divided into two groups and treated as same as the first experiment in root canal preparation and irrigation. After irrigation, the apical canal wall was observed using SEM. Results: There was no significant difference in bacterial growth and removing the smear layer between the group using EOW and that using saline solution, 30 ml/L H2O2 and 75 g/L EDTA solution. Conclusion:The results indicate EOW is useful as a clinical root canal irrigation solution.
