A tooth with a pulp having a rare degenerative change was found among numerous extracted tooth specimens. Microscopically eosinophilic dimunutive granules existed around vesseles in the coronal pulp. These were stained positively with Congo red and periodic acid-Schiff. Electron microscopic observation revealed that granules were composed of bundles showing one of the characteristic appearances of amyloid deposition.
