Abstract
Element sensitive X-ray tomography has been applied to detect the metal dif fusion from the amalgam tooth filling into the tooth. By performing tomogra phies with energies above and below the K-edges of the various metals of th e amalgam, it is possible to determine their distribution. Here presented a re the results of measurements at ID15 and ID19 of the ESRF. To improve the sensitivity of our measurements a method for contrast enhancement for proj ections was developed.
