The concentration gradient and distribution of a metallic constituent in dentin which has been subjected to iontophoresis, using a water solution of silver diamine hydroxide and zinc chloride, were analyzed by means of EPMA as a basic study for pulp capping or cavity lining. Line scanning analyses parallel to the tooth axis showed that the transportation distance of metallic ions depends strongly on potential, period of iontophoresis and structural differences in dentin. Although metallic silver or zinc was found in the dentinal tubules, there was one case in which no metal was observed. The change in the distribution can be described as power function.
作为牙髓盖髓术或窝洞衬层的基础研究，采用氢氧化二氨合银和氯化锌水溶液，对经离子导入处理的牙本质中金属成分的浓度梯度和分布进行了电子探针微分析（EPMA）。平行于牙轴的线扫描分析表明，金属离子的迁移距离在很大程度上取决于电位、离子导入时间以及牙本质的结构差异。尽管在牙本质小管中发现了金属银或锌，但有一例未观察到金属。分布的变化可用幂函数来描述。
