An epidemiological study was performed in 250 persons who five years previously had been treated with extensive metallic reconstructions. To gain representative information these persons were selected at random from three Local Social Insurance Offices in different parts of Sweden. Those person, who in a questionnaire reported symptoms that could be alleged to have been caused by oral galvanic actions, were offered free clinical examination including quality evaluation and free measurements of potentials and polarizations of the metallic dental restorations. Persons from a subgroup to this study not suffering from any oral discomforts were chosen as a control group. Comparisons between the two groups were made in regard to current creation at metallic contacts, clinical quality and mucosal conditions. In none of the statistical analyses performed, differences could be shown between the groups. A tendency to higher amounts of restorative care at comparatively lower level of technical quality could, however, be noticed in the group of persons with oral symptoms which they themselves associated with oral galvanism.
对250名5年前接受过广泛金属修复治疗的人员进行了一项流行病学研究。为了获取具有代表性的信息，这些人员是从瑞典不同地区的三个地方社会保险办公室随机挑选出来的。那些在问卷中报告了可能被认为是由口腔电流作用引起的症状的人员，被提供了免费的临床检查，包括质量评估以及金属牙修复体的电位和极化的免费测量。从该研究的一个亚组中挑选出没有任何口腔不适的人员作为对照组。对两组在金属接触处的电流产生、临床质量和黏膜状况方面进行了比较。在进行的所有统计分析中，两组之间均未显示出差异。然而，在那些自述有与口腔电流相关症状的人员组中，可以注意到在技术质量相对较低的情况下，修复治疗量有增加的趋势。
