Abstract
Sialolithiasis results from obstruction of salivary flow by a sialolith (salivary stone), which may be found anywhere in the ductal system. The incidence of this condition is higher in the submandibular glands, probably because of the anatomical form and physiological features. The present report describes the case of a healthy 54-year-old black female patient in whom a hardened, normochromic, painless swelling on the right side of the floor of the mouth was noticed during routine oral clinical examination. Occlusal radiography revealed an extensive elongated radiopacity in the submandibular region, in association with clinical characteristics suggesting salivary calculus. Surgery was performed to remove the sialolith, which measured 35mm×7.0mm. This case report is relevant due to the absence of symptoms in the presence of an extremely large sialolith.
