The salivary calculi is not an uncommon condition encountered in practice. Calculi of the salivary glands may from in all the salivary glands or ducts, but the larger proportion are found in the submaxillary gland or duct. They are found more frequently in the ducts, approximately´ 85 per cent, than in the glands.
The reason for the formation of salivary calculi is not fully :understood. Perhaps in some cases, epithelial debris due to inflammation of salivary duct, or foreign body entered into the salivary duct through duct orifice may be the initiating factor. Although the pathogenesis is not known, there appear to ba several factors that predispose to the more common occurrence of stones in the submaxillary duct.
Authors have recently experienced an interesting case´ of salivary calculi which seems to be due to a foreign body, a fish bone, in the left submaxillary duct in a 29-year-old male.
