hyposalivation การใช้

Dehydration, radiotherapy involving the salivary glands, and several diseases can cause hyposalivation or a change in saliva consistency and hence a complaint of xerostomia.
The study of masticatory force in different types of patients such as patients with polymyositis and dermatomyositis shows that hyposalivation and mucosal alterations can be related to the pathology of masticatory system.
Radiation therapy may cause permanent hyposalivation due to injury to the oral mucosa containing the salivary glands, resulting in dry mouth or xerostomia, whereas chemotherapy may cause only temporary salivary impairment.
Persons with reduced salivary flow or hyposalivation often suffer from dry mouth or xerostomia, which can result in severe dental caries ( tooth decay ) as a result of the loss of the protective effects of saliva.
