The study describes a method for the determination of corrosion kinetics of amalgams from the buccal cavity by measuring initial and evolutive electrical potentials in parallel with an evaluation of clinical factors. It also deals with factors which might be improved in this connection. The method was applied experimentally in 125 cases with restoration therapy with silver amalgam, and a digital milivoltmeter for direct current was used, of 0.2% precision class with silver chloride electrodes to which two probes have been adapted. The values determined varied between--320 and--82 milivolts. The advantages as compared with previously used methods are the following: an electrical measurement of resistance to corrosion of amalgams, and improvement of factors which influence corrosion.
该研究描述了一种通过并行测量初始和演变电势并评估临床因素来测定口腔内汞合金腐蚀动力学的方法。它还探讨了在这方面可能得到改善的因素。该方法在125例银汞合金修复治疗病例中进行了实验应用,使用了一台精度为0.2%的直流数字毫伏表,配有氯化银电极,适配了两个探头。测定的值在-320至-82毫伏之间。与先前使用的方法相比,其优点如下:对汞合金耐腐蚀性能进行电学测量,以及改善影响腐蚀的因素。
