A case of bilateral submandibular sialolithiasis was reported. A 62-year-old woman was referred to us because of painless swelling in the left submandibular gland.
Roentgenographic examination showed a presence of salivary stones in the bilateral submandibular ducts.
Two salivary stones were removed from the left submandibular duct and one from the right submandibular duct intraorally.
The stones were examined with the scanning electron microscope equipped with an electron probe X-ray microanalyzer.
The cut surface of the salivary stones showed a structure consisted of concentric layers surrounding one central core. Calcium, phosphorus, and sulphur were detected in every stone as the main elementary compositions.
