Abstract
Sialoliths are the most common diseases of the salivary glands. They may occur in any of the salivary gland ducts but are most common in Wharton's duct and the submandibular gland. This report presents clinical and radio graphical signs of two unusually large sialoliths which exfoliated by itself. There were painless swellings on the floor of the mouth in both cases. Radiographical examination revealed large irregular radioopaque mass superimposed right canine and premolar areas. Sialoliths were yellow in color and approximately 1.8 cm and 2.1 cm in size.
