Amalgam restorations have been implicated both in contact sensitivity reactions and in lichenoid reactions. This appears to be related principally to the mercury content, although other metals cannot be discounted. The cases of two patients are reported who showed features of lichenoid reactions of the oral mucosa, in addition to features of a contact hypersensitivity to mercury. The mucosal lesions resolved following replacement of the amalgams with non-metallic restorations. Consideration is given to the selection of materials and procedures currently available for treatment of these patients. This paper supports the view that sensitivity to heavy metals must be considered as a possible cause of erythematous and lichenoid reactions of the oral mucosa.
汞合金修复体与接触性敏感反应和苔藓样反应均有关联。这似乎主要与汞含量有关，不过其他金属也不能排除在外。报告了两例患者的病例，他们除了对汞有接触性超敏反应外，还表现出口腔黏膜苔藓样反应的特征。用非金属修复体替换汞合金后，黏膜病变得以消退。文中考虑了目前可用于治疗这些患者的材料和方法的选择。本文支持这样一种观点，即必须将对重金属的敏感性视为口腔黏膜红斑和苔藓样反应的一个可能原因。
