Hydrogel reservoir delivers artificial saliva to relieve xerostomia

WEST LAFAYETTE, Ind., US: Xerostomia is frequently encountered in patients receiving haemodialysis, chemotherapy or radiotherapy and is strongly associated with polypharmacy, a growing concern in ageing populations. Despite a range of available treatments, achieving reliable and long-lasting relief has remained elusive. To address this need, researchers in the US have developed a reusable hydrogel reservoir that gradually releases artificial saliva in the mouth, potentially offering sustained relief for patients with dry mouth.
