Applicability of neutral electrolyzed water for cleaning contaminated fixed orthodontic appliances.

Introduction: We investigated whether water jet washing with neutral electrolyzed water (NW) can be an easy and safe self-performed cleaning method for oral environments of fixed orthodontic appliance-wearing patients. In line with this, we examined the bactericidal effects and dissolution behaviors of metal elements released from appliances.

Methods: A metal or resin bracket ligated with a metal wire and metal bracket adhered to an apatite-pellet were used as specimens.
