利用电化学电位技术对牙髓锉和扩眼器进行分析，结果表明，不同材质的牙髓锉和扩眼器在使用碳或不锈钢、冲洗液、蛋白物质的存在与否以及抑制剂的类型和浓度等方面表现出了显著的差异。提高电化学活性的因素是碳钢的使用以及次氯酸钠和含有蛋白质的EDTA-Na溶液的使用。与次氯酸钠溶液相比，过氧化氢特别是EDTA-Na溶液抑制了极化趋势，使其活性降低。除50%柠檬酸外，硅酸钠是唯一有效的抑制剂，在3%柠檬酸水平下，某些情况下击穿电位提高0.8 v。焦磷酸钠、亚硝酸钠、氟化钠、苯甲酸钠、苯并三唑、水溶液和表面活性剂均无效。
Using potentiodynamic electrochemical techniques to endodontic files and reamers indicated drastic differences in behavior depending on carbon or stainless steel, irrigating solution, presence or absence of protein matter, and type and concentration of inhibitor. Factors that increased the electrochemical activity were the use of carbon steel and solutions of sodium hypochlorite and EDTA-Na containing protein matter. Hydrogen peroxide and especially EDTA-Na solution depressed the polarization trends to less active behavior compared with sodium hypochlorite solution. Sodium silicate, except in 50% citric acid, was the only effective inhibitor, which at the 3% level, increased the potential of breakdown 0.8 v in some cases. Solutions of sodium pyrophosphate, sodium nitrite, sodium fluoride, sodium benzoate, benzotriazole, aqueous sol, and surfactant all proved ineffective.
