Weddellite in submandibular gland calculus.
Scanning electron microscopy of a submandibular sialolith showed octahedral and dipyramidal crystals located at the surface layer of cortex. The crystal habits observed were consistent with those of a tetragonal crystal system. X-ray microdiffraction revealed the presence of weddellite. The origin of weddellite within the calculus remains to be determined.
