Salivary duct stones are crystallized minerals in the ducts that drain the salivary glands. Salivary duct stones are a type of salivary gland disorder.
Alternative Names:
Sialolithiasis
Causes, incidence, and risk factors:
During eating, saliva (spit) is produced by the salivary glands in the mouth. The chemicals in saliva can crystallize into a stone that can block the salivary ducts. When saliva cannot exit a blocked duct, it backs up into the gland, causing pain and swelling of the gland. The submandibular glands, at the back of the mouth on both sides of the jaw, are most often affected by stones.
The symptoms are usually most noticeable when eating or drinking.
Signs and tests:
An examination of the head and neck by the health care provider or dentist shows one or more enlarged, tender salivary glands. The doctor may be able to feel the stone during examination.
X-rays of the face or a CT scan can confirm the diagnosis.
