Prosthodontic Management of Xerostomia Using Salivary Reservoir Complete Denture: A Case Report

Xerostomia is defined as dryness of the mouth resulting from reduced salivary secretion. It is commonly associated with systemic conditions such as diabetes mellitus and can significantly impair oral functions, including mastication, speech, and denture retention. This case report describes the prosthodontic management of a completely edentulous female patient with xerostomia and a history of diabetes mellitus who presented with difficulty chewing and swallowing. Maxillary and mandibular complete dentures were fabricated using conventional techniques. To address the lack of salivary flow, a salivary reservoir was incorporated into the palatal region of the maxillary denture. The reservoir was designed to allow the continuous release of artificial saliva, thereby improving oral lubrication. The prosthesis resulted in enhanced denture retention, improved comfort, reduced mucosal irritation, and better mastication and speech. Salivary reservoir dentures offer a simple, cost-effective, and practical solution for managing xerostomia in edentulous patients. This approach significantly improves quality of life and overall oral function in affected individuals.
