Quick Reference

An iatrogenic lesion caused by traumatic implantation of dental amalgam into soft tissue. It is characterized by a blue-grey discoloration, usually located on the gingiva or alveolar mucosa. As the amalgam corrodes, macrophages take up the amalgam particles and collagen fibres become darkly stained by the silver component. Treatment by excision is usually unnecessary, except for cosmetic reasons or to exclude the diagnosis of a melanotic lesion.
