title: [Gingiva pigmentation in PFM and amalgam restorations].
abstract: A 27-year-old white female patient, claiming her psychiatric disorder to stem from a mercury intoxication caused by amalgam restorations, was examined. Circumscribed gingival pigmentations were found around PM crowns cemented on amalgam fillings. The histologic and metallographic examination of the incisional biopsy sample of the pigmented lesion together with the toxicological results revealed no indication of a mercury intoxication. In order to enable corrosive reactions to proceed as slowly as possible PM crowns should not be in contact with amalgam fillings, as this case showed.
