A method for in vivo measurements of potentials and polarizations of metallic dental restorations was presented. The precision of this method allowed for calculation to be made of the electrochemical action in the oral cavity in terms of currents created at contact between metallic restorative materials. With this method, an epidemiological investigation was performed on persons, who had received dental treatments including extensive metallic restorations. Those persons suffering from oral symptoms allegedly caused by oral galvanism were not found to have higher electrochemical action in the oral cavity than persons, selected as a control, without symptoms ascribed to oral galvanism. Persons ailing from this type of symptoms showed, however, lower threshold levels for electric stimulation, examined with an electrogustometric method, than persons without symptoms. Finally, determination of the saliva concentrations of various metallic components with atomic absorption spectrophotometry did not reveal any differences between persons with or without metallic restorations. Neither were any correlations found between saliva ion concentrations and the magnitude of currents created at metallic contact between dental restorations.
提出了一种用于体内测量金属牙科修复体电位和极化的方法。该方法的精度使得能够根据金属修复材料之间接触产生的电流来计算口腔中的电化学作用。使用该方法，对接受过包括广泛金属修复在内的牙科治疗的人员进行了流行病学调查。那些据称因口腔电流刺激而出现口腔症状的人，在口腔中并未被发现比被选为对照的无症状者具有更高的电化学作用。然而，患有此类症状的人用电味觉测量法检测时，其电刺激阈值水平低于无症状者。最后，用原子吸收分光光度法测定各种金属成分的唾液浓度，未发现有金属修复体者与无金属修复体者之间存在任何差异。在唾液离子浓度与牙科修复体之间金属接触产生的电流大小之间也未发现任何相关性。
