Tooth decay The digestive enzymes in saliva begin breaking down your food before you have even swallowed it and saliva is most commonly released in response to the smell and taste of food. Additional functions of saliva include helping us to swallow and talk.
Saliva is produced by several glands located in the mouth and throat. The major salivary glands then transport the saliva through tiny tubes called salivary ducts which eventually release the saliva into various places in your mouth, especially under your tongue and on the floor of your mouth.
The three pairs of major salivary glands are called the parotid, submandibular, and sublingual glands. In addition to the major saliva glands, there are multiple smaller glands, called minor salivary glands, located in your lips, cheeks, and throughout the tissue lining your mouth. Causes Conditions such as dehydration which cause thickening, or decreased water content of the saliva can cause the calcium and phosphate in saliva to form a stone.
The stones often form in the salivary ducts and can either totally obstruct the salivary duct, or partially occlude it. You may develop sialolithiasis even if you are healthy, and a cause may not always be able to be pinpointed.
However, when the flow of saliva becomes completely blocked it may cause the associated salivary gland to become infected. This is important to tell your doctor since it may help differentiate sialolithiasis from other conditions. Diagnosing Sialolithiasis An otolaryngologist , or ENT, is a physician qualified to diagnose and treat sialolithiasis.
Although doctors in other specialties may also diagnose or treat this condition. Your doctor will consider your medical history and examine your head and neck, including the inside of your mouth. Sometimes the stone can be felt as a lump. Historically a sialograph, where dye is injected into the salivary duct followed by an x-ray, was used, however, this is more invasive than modern MRI or CT scans which are now more likely to be used. Sometimes a doctor can push the stone out of the duct and into the mouth by using a blunt object and gently probing the area.
Large salivary duct stones may be more difficult to remove and sometimes require surgery. Sometimes a thin tube called an endoscope can be inserted into the duct. If the stone can be seen with the endoscope the doctor may be able to insert another tool that is then used to pull the stone out. In the case of an infected gland, your physician may prescribe an oral antibiotic.
Never take antibiotics without seeing a physician. Was this page helpful? Thanks for your feedback! Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life. There was an error. Please try again. What are your concerns?
Ein kleinerer Teil der Steine wird mit der extrakorporalen Lithotripsie behandelt. Salivary stone formation affects the submandibular gland in about 80 per cent, the parotid gland in 20 per cent and rarely the sublingual gland. The typical symptoms such as painful swelling lead to the diagnosis of sialolithiasis which can be proved by ultrasound — the imaging method of choice. In special cases endoscopy of the salivary ducts can be performed. Instead of gland extirpation a differential therapeutic concept has been developed nowadays which takes location and size of a stone into account. In cases of parotid stones basket extraction can be tried. Also extracorporeal sonographically controlled lithotripsy plays a major part in therapy.
Classification[ edit ] The term is derived from the Greek words sialon saliva and lithos stone , and the Greek -iasis meaning "process" or "morbid condition". A calculus plural calculi is a hard, stone-like concretion that forms within an organ or duct inside the body. They are usually made from mineral salts , and other types of calculi include tonsiloliths tonsil stones and renal calculi kidney stones. Sialolithiasis refers to the formation of calculi within a salivary gland. If a calculus forms in the duct that drains the saliva from a salivary gland into the mouth, then saliva will be trapped in the gland. This may cause painful swelling and inflammation of the gland. Inflammation of a salivary gland is termed sialadenitis.
