From: Detection of trace metallic elements in oral lichenoid contact lesions using SR-XRF, PIXE and XAFS
SR-XRF spectra of specimens #10 and #11.
(a) The peaks of Ag, Pd, Au and Cu were observed. These are the major components of the most popular dental alloy (Au-Pd-Ag-Cu alloy). (b) The peak of Bi was observed. Bi is a dental material contained in root canal sealers.
