Comparative studied were performed in healthy subjects without metals in their oral cavities and in individuals having different metal alloys (gold, steel, amalgam) in their mouths and presenting with various complaints such as xerostomia, burning mucosa, etc. It was found that the contents of alkaline and acid phosphatases, alpha-amylase, K+, Na+ and Cl- in saliva increased significantly with the increase in total corrosion potential when non-precious metal alloys, especially different types of alloys, were present. Parallel to this, the frequency and the intensity of the complaints increased.
对口腔内无金属的健康受试者以及口腔内有不同金属合金（金、钢、汞合金）且伴有口干、口腔黏膜灼痛等各种不适症状的个体进行了对比研究。结果发现，当存在非贵金属合金尤其是不同类型的合金时，唾液中碱性磷酸酶、酸性磷酸酶、α淀粉酶、钾离子、钠离子和氯离子的含量会随着总腐蚀电位的升高而显著增加。与此同时，不适症状的频率和强度也增加了。
