Investigating the Presence of Mercury under a Dental Restoration Using Synchrotron K-Edge Subtraction Imaging

“…Patients with dental amalgam restorations intake mercury vapor by inhalation, may ingest elemental mercury, or may swallow tiny fragments of amalgam [1]. X-ray absorption near-edge spectroscopy (XANES) of extracted teeth that were restored with dental amalgam for more than 20 years identified dentinal tubules as another possible portal for patients' intake of mercury [2]. K-edge subtraction (KES) imaging is a state-of-the-art capability at the Biomedical Imaging and Therapy (BMIT) beamline at the Canadian Light Source (CLS).…”

“…The recent paper by Harris et al (2008) showed the relation between mercury migration from amalgam into a tooth restored with dental amalgam by using the X-ray absorption near-edge spectroscopy (XANES) method.…”
