Sažetak

Proton induced X-ray emission spectroscopy (PIXE) has been used to
determine the intensity of metals from crowns in human teeth. In order to measure elements distribution across the tooth section, proton beam (3 MeV) has been collimeted to provide a spatial resolution of 300 jj,m. The samples were selected according to the time of insertion of crowns and the kind of alloys they were made of. The results show the intensities of gold, zinc and copper in abutment teeth. It was not found any intensity of paladium and amount of silver was not significant.
