A sialadenitis (= sialadenitis) is generally caused by a saliva stone (= sialolith), which is caught in the duct of the salivary gland: In the behind accumulated saliva bacteria and viruses can multiply and cause inflammation. For the formation of salivary stones (known Sialolithiasis) - and thus for the subsequently formed sialadenitis - as possible causes are a changed composition of saliva and pre-existing diseases (such as cystic fibrosis or mumps) questioned with narrowed gland ducts. A salivary stone can humans generally develop in any salivary gland of the head, most of it, however, occurs in one of the major salivary glands. Predominantly salivary stones are formed there in the third to fifth decade of life, but also children can be affected.''
