[The relationship of function and pathology of submandibular gland with sialolithiasis]

Submandibular glands with sialolithiasis are analysed histopathologically. The formation of the calculi of the submandibular glands may be related to the sialoadentitis and to the changes of saliva composition. Mineralization of the organic matrix may be one of the cause of calculus formation. By comparison of the glandular function with the pathology of the gland, it shows that the reduction of glandular function is associated with the severity of grandular inflammation. When function index is normal, grandular inflammation is in the Stage I or II, while it decreases or zero, grandular inflammation is in the Stage III or IV. Glandular function index may predict the severity of grandular inflammation.
