Efficacy of Topical Sialogogues in Xerostomia Treatment on Chronic Residents of C.H.P.L.

Institutionalized psychiatric patients on chronic psychotropic medication are prone to xerostomia due to reduced salivary flow. This study evaluated the effectiveness of a topical sialogogue gel (Xeros Dentaid®) in relieving drug-induced dry mouth in 81 residents at the Lisbon Psychiatric Hospital Centre (C.H.P.L.). Over 15 days, unstimulated and stimulated salivary flow rates, pH, and buffer capacity were measured before and after application. Results showed a significant increase in salivary flow (p < 0.001) and improved subjective symptoms. Topical sialogogues may represent an accessible and effective strategy for managing xerostomia in this vulnerable population.
