根管冲洗是辅助根管机械预备有效清理的关键,根管冲洗能有效去除细菌微生物。次氯酸钠是目前应用最广的根管冲洗液,它的缺点是毒性较高。电化学活性水是一种优于次氯酸钠的根管冲洗液,它由纯净水和低浓度盐制成,对人体无毒无害,具备良好的抗菌性,且毒性低。本文就电化学活性水用作根管冲洗液的机理、安全性和效果等进行综述。 Root canal irrigation is the key to effective mechanical root canal cleaning, root canal irrigation can effectively remove bacteria and microorganisms. Sodium hypochlorite is the most widely used root canal irrigation solution, its disadvantage is higher toxicity. Electrochemically active water is a root canal rinsing solution superior to sodium hypochlorite. It is made from pure water and low concentration salts, is non-toxic to the human body, has good antibacterial properties and low toxicity. This article reviews the mechanism, safety and efficacy of electrochemically active water for root canal irrigation.
