A ramarkable gingival pigmentation around the restorated teeth was successfully treated by simple surgical removal ; incision & coagulasion of deposits by electrosurgery. Before the treatment, a biopsy from the pigumented gingiva was histopathologically exantined, and a lot of small pigment deposits were found in the lamina propria with no inflammation, but not in the epitherium. Elements constructing the deposits were also determined by means of an electron probe X-ray microanalyser. Silver was fotund to be the priutcipal element of the deposits, but not found at all in the crown metal. These results suggested that the cause of the pigmentation was implantation of metal fragments from metal cores during abutment teeth preparation. Therefore, the surgical removal was performed. Relapses have not occured for 3 years since the treatment.
