The term lichenoid reaction (lichenoid eruption or lichenoid lesion) refers to a lesion of similar or identical histopathologic and clinical appearance to lichen planus (i.e., an area which resembles lichen planus, both to the naked eye and under a microscope). [7] [8] Sometimes dental materials or certain medications can cause lichenoid ...
Both those opposed and those not opposed to dental amalgam recognize that amalgam has been found to be a rare contributor to localized and temporary tissue irritation known as oral lichenoid lesions. [ 14 ] [ 68 ] [ 69 ] [ 72 ] These mild, lichenoid reactions have also been reported in composite resin fillings. [ 73 ]
Urticaria is a vascular reaction of the skin characterized by the appearance of wheals, which are firm, elevated swellings of the skin. [105] Angioedema , which can occur alone or with urticaria, is characterized by a well-defined, edematous swelling that involves subcutaneous tissues, abdominal organs, or upper airway.

Foreign body reactions appear as red or red and white, possibly painful longstanding lesions similar to desquamative gingivitis, or be granulomatous or lichenoid in nature. Tiny particles of dental materials (e.g. abrasive polishing pastes) may become impregnated in the gingival tissues and trigger a chronic inflammatory cell response. [5]
