Oral amalgam pigmentations (tattoos): a retrospective study
Owens / Johnson / Schuman
Oral amalgam tattoos are typically asymptomatic, benign, solitary or multiple clinical lesions produced by inadvertent placement of dental silver amalgam restorative material into the oral soft tissues. Diffuse lesions often display a grayish brown discoloration while other tattoos pres ent a darker blue-black contrast. One hundred sixty-eight biopsy reports that confirmed the diagnosis of amalgam tattoo were analyzed to find age, sex, and race of the patients and size, location, and duration of occurrence of the lesions. Among the 168 cases, 235 individual tissue specimens were identified. A majority of the specimens were taken from the buccal mucosa, gingiva, and alvolar mucosa. The most common site for the lesion was the mandibular arch. The size of the individual specimens ranged from 0.10 cm to 1.50 cm. Almost two thirds of the specimens were 0.40 cm or less.
