Abstract
The most common pathogenesis of sialolith formation is an abnormality in calcium metabolism, salt precipitation and crystallized mineral accumulation. Sialolithiasis is observed mainly in submandibular gland, accounting for 85% of cases. There are several causes of this high incidence in the submandibular gland. One of the most prevalent reasons is that the Wharton's duct is the longest salivary duct (5 cm in length) with sharp curves and a narrow duct (diameter=2-4mm). Moreover, the Wharton's duct opens into the floor of the mouth near the incisors, making it difficult for a foreign body to stimulate or obstruct it. This study reports a rare case in which a foreign body (i.e., a fish bone) in the submandibular gland progressed to sialolithiasis, subsequently inducing sialoadenitis.
