xerostomia
Pronunciation: /ˌzɪroʊˈstoʊmiə/
Subjective complaint of dry mouth resulting from decreased salivary gland function.
Full Definition
Xerostomia refers to the patient's subjective sensation of oral dryness, which may result from medication side effects, systemic diseases, radiation therapy, or surgical damage to salivary glands during oral and maxillofacial procedures. This condition significantly impacts oral health by increasing the risk of dental caries, periodontal disease, and oral infections. Management in the surgical setting includes salivary gland preservation techniques, saliva substitutes, and modification of medications when possible.
Usage
Usage note: Distinguish from 'hyposalivation' which refers to measurably decreased salivary flow.
