Calculous disease of the submandibular gland is four times more common than that of the parotid gland. About 70% of submandibular gland calculi are radiopaque.
It is thought that the higher pH and viscosity of the submandibular gland secretions, and the fact that the saliva has to travel uphill to get excreted contribute to the higher incidence of sialolithiasis in the submandibular gland .
The workup for suspected calculous disease of salivary glands (painful glands worsened by chewing) begins with radiographs. If a radiopaque calculus is not found, then CT may be obtained. MR sialography (analogous to MRCP) is >90% accurate for the detection of sialolithiasis.
Sialadenitis is inflammation of the gland and is often associated with ductal ectasia (sialectasis) and most often caused by sialolithiasis. Microabscesses may be seen with sialectasis and/or sialadenitis. Sialodochitis is the inflammation of the ductal system.
Sialadenitis with sialodochitis without other systemic symptoms is referred to as Sjögren type I (also known as Mikulicz disease). When sialadenitis with sialodochitis are associated with a collagen vascular disease, it's referred to as Sjögren type II.
Because people with Sjögren disease are ten times more likely to develop lymphoma, make sure to look closely at the rest of the neck for lymph nodes. The lymphoma may also develop in the salivary glands themselves, so look closely at the glands for signs of lymphoma.
Without Roentgen i dnt think Medicine and Dentistry woud have this much of a development..Anyway thanks fr the facts you shared..
