Scores on the Beck Depression Inventory were compared for 25 women who had silver dental fillings (amalgams) and for 23 women without amalgams. Women with amalgams had significantly higher scores and reported more symptoms of fatigue and insomnia. Anger scores from the State-Trait Anger Expression Inventory showed that the women with amalgams had statistically significantly higher mean scores on expressing anger without provocation and experiencing more intense angry feelings. The women without amalgams scored significantly higher on controlling anger, which suggested they invested more energy in monitoring and preventing the experience and expression of anger. Anxiety scores from the State-Trait Anxiety Inventory showed the women with amalgams scored significantly less pleasant, satisfied, happy, secure, and steady, and had a more difficult time making decisions. They had significantly higher Trait Anxiety scores. The women with amalgams also had significantly higher levels of mercury in the oral cavity before and after chewing gum. The study suggests that amalgam mercury may be an etiological factor in depression, excessive anger, and anxiety because mercury can produce such symptoms perhaps by affecting the neurotransmitters in the brain.
对25名有银色补牙填充物（汞合金）的女性和23名没有汞合金补牙的女性的贝克抑郁量表得分进行了比较。有汞合金补牙的女性得分显著更高，且报告有更多疲劳和失眠症状。状态-特质愤怒表达量表的愤怒得分显示，有汞合金补牙的女性在无挑衅情况下表达愤怒和体验更强烈愤怒情绪方面的平均得分在统计学上显著更高。没有汞合金补牙的女性在控制愤怒方面得分显著更高，这表明她们在监测和预防愤怒的体验及表达上投入了更多精力。状态-特质焦虑量表的焦虑得分显示，有汞合金补牙的女性在愉悦、满意、快乐、安全感和稳定感方面的得分显著更低，且做决定时更困难。她们的特质焦虑得分显著更高。有汞合金补牙的女性在咀嚼口香糖前后口腔中的汞含量也显著更高。该研究表明，汞合金中的汞可能是导致抑郁、过度愤怒和焦虑的一个病因，因为汞可能通过影响大脑中的神经递质而产生这些症状。
