ABSTRACT

Objectives: To assess total basal and stimulated salivary flow and the prevalence of xerostomia, to estimate the association between basal saliva and the sensation of dryness of the mouth in healthy geriatric patients with diabetes mellitus and/or hypertension.
Study Design: We selected 440 patients and divided these into four groups based on their health condition. Sialometry was performed to measure unstimulated (basal) and stimulated whole salivary flow, measured using gravimetric analysis. A questionnaire was devised to assess the presence of xerostomia and its associated indications and symptoms.
Results: Basal salivary flow in diabetics with hypertension was significantly lower than that in healthy subjects (p =0.023). Stimulated salivary flow caused by chewing was significantly different in patients with diabetes and/or hypertension compared to that in healthy subjects (p‹0.001). The prevalence of xerostomia in patients with diabetes and/or hypertension was higher compared to that in healthy individuals (p‹0.001). Patients with xerostomia had lower levels of basal saliva compared to those that felt no dryness in the mouth (p‹0.001). Subjects with xerostomia displayed difficulty swallowing some foods, difficulty speaking due to a lack of saliva, dry throat, and a need to drink water in order to be able to chew dry food. In these individuals, basal and stimulated salivary flow was lower.
Conclusions: The patients with diabetes and hypertension in our study had lower levels of salivary flow and a higher level of xerostomia than did healthy subjects, suggesting that salivary secretion and the prevalence of xerostomia are affected by the subject's medical condition.
