Dry
mouth is a common complaint, usually associated with some degree
of salivary gland dysfunction. This is a significant symptom that
often signals a systemic disorder, has a major impact on oral
functions, and negatively affects quality of life. The symptom
is non-specific and a comprehensive and organized diagnostic approach
is essential. With appropriate management, oral dryness can be
relieved, associated morbidities alleviated, and preventive measures
instituted.
Research
studies in dry mouth have been hampered by a lack of well-validated means
of assessing the severity and changes in the symptom. Many studies
rely on simple global questionnaires to determine clinical benefit.
Increased research is indicated to improve the sensitivity of
dry mouth assessment and correlate symptomatic improvement with
more objectively measured improvements in oral functions.
