Giant submandibular sialolith and residual cyst on contralateral side: A case report of tooth like stone

Sialolithiasis has been reported to be the most common disease of the salivary gland affecting 12 individuals per 1000 of the adult population. It is the most common cause of acute and chronic infections of salivary gland and accounts for greater than 50% of the diseases involving large salivary glands. Sialolith greater than 15mm in any one dimension or 1 gram in weight have been classified as giant sialoliths in literature. Residual cyst may be radicular, dentigerous or any other cyst which persists after the removal of its associated tooth. They account for approximately 10% of all odontogenic cysts and are usually asymptomatic. The aim to the present article is to report simultaneous occurrence of giant submandibular sialolith with unsusual shape and residual cyst on the contralateral side. The interesting point to note is the strikingly similar appearance of sialolith to canine.
