Amalgam reactions are generally considered type IV hypersensitivity reactions [26]. Another histologic feature present in amalgam contact reactions and not a typical finding in oral lichen planus is the presence of a deep inflammatory infiltrate rather than inflammation confined to the lamina propria subjacent to the epithelial basal cells.
