title: Large calculi of the submandibular salivary glands.
abstract: Salivary calculi occur in the submandibular and parotid glands, and their ducts, and occasionally reach a large size. However, little information is available on the composition of these giant stones. 2 cases are reported of unusually large calculi of the submandibular salivary glands. The glands were excised, and the results of chemical and infrared analysis of the calculi are presented.
