ABSTRACT
Sialolithiasis is the formation of a calcified obstruction within the salivary duct. It may form in any of the major or minor salivary glands or their ducts. Overall, 80% to 90% of salivary gland stones occur in the submandibular gland. Sialoliths commonly measure from 5 to 10 mm in size and all stones over 10 mm can be reported as sialoliths of unusual size. In this study, we report a large sialolith presenting without clinical symptoms. The CBCT images of a 52-year-old man who referred for implant treatment evaluation of lower jaw showed a large radiopaque mass in floor of mouth. The patient did not have any history of pain or pus, and this sialolith was not his chief complaint. The sialolith was surgically removed. Some sialoliths, despite their remarkable size, can be a diagnostic and therapeutic challenge for the clinician. Appropriate diagnosis and treatment with minimal side effects is very important
