Salivary levels of hyaluronic acid in female patients with dry mouth compared with age-matched controls: a pilot study.

Little is known regarding the association between the level of hyaluronic acid (HA) in saliva and dry mouth status. The aim of this study was to evaluate the salivary levels of HA in female patients with dry mouth (perceived xerostomia and hyposalivation) and compare them with age-matched controls. We studied 46 females, and classified them into two groups based on perceived xerostomia and salivary flow rate, as well as a control group without symptoms.
