Salivary glands produce saliva when we eat to help aid in chewing and digestion. Chemicals contained in saliva can crystallize to form a calculi or stone and block the ducts of the salivary glands. When a duct is clogged by calculi, this inhibits saliva from being able to exit the duct therefore causing pain and inflammation of the gland. The most common salivary glands to be affected by calculus are the submandibular glands, although any salivary gland can develop stones.
1 out of every 30,000 persons can be affected by salivary gland calculi. To determine if there is a stone or where it is located there are different modalities to choose from: CT, MRI, NM, and US.
