我们设计了一种灵活的针尖电解单元，采用硼掺杂金刚石粉末（BDDP）为基础的聚合物复合材料用于牙科治疗。金属线表面（阳极）被包含BDDP和20%Naflon（R）分散体的BDDP基聚合物复合材料以2/1（w/w）的混合比涂覆。带有离子交换膜的铂带螺旋缠绕在金属丝表面作为阴极。当在水中的阳极和阴极之间施加直流电压时，产生臭氧和氧化中间体。该装置显示出几乎相同的灭菌能力，获得1重量%的含水NaOCl在体外评估的人牙齿的根管。此外，基于BDDP的聚合物复合材料具有优异的耐久性;即使在电解期间反复弯曲，也几乎不开裂或剥离。我们相信，我们的工作将使一个实用的牙科治疗单位的发展。(C)2016年6月，作者。由爱思唯尔公司出版
We devised a flexible pinpoint electrolysis unit employing a boron-doped diamond powder (BDDP)-based polymer composite for use in dental treatment. A metal wire surface (the anode) was coated by the BDDP-based polymer composite comprising BDDP and a 20% Naflon (R) dispersion at a mixing ratio of 2/1 (w/w). A Pt ribbon with an ion-exchange membrane was spirally wound around the metal wire's surface for use as the cathode. When a direct current voltage was applied between the anode and cathode in water, ozone and oxidative intermediates were generated. The unit showed almost the same sterilization ability as obtained by 1 wt% aqueous NaOCl in an in vitro assessment of the root canals of human teeth. Moreover, the BDDP-based polymer composite has excellent durability; hardly cracking or peeling, even with repeated bending during electrolysis. We believe that our work will enable the development of a practical unit for dental treatment. (C) 2016 The Authors. Published by Elsevier B.V.
