Xerostomia, its influence on oral mucosa of partial denture wearers-a review

Abstract

Xerostomia, also called dry mouth, is associated with change in composition of saliva or reduced saliva. Hyposalivation may cause dental caries, acid erosion, oral candidiasis, sialadenitis, or even dysgeusia. Hyposalivation or change in saliva consistency can be caused due to dehydration, radiotherapy involving salivary glands, chemotherapy and several diseases. Hyposalivation causes difficulty wearing dentures when swallowing or speaking. There may be generalized mucosal soreness and ulceration of the areas covered by the dentures. A salivary film layer is present for lubricating and hydrating the mucosa beneath the denture base and for protection. RPDs are a common treatment option for partially dentated individuals as they allow replacement of up several missing teeth, across either single or multiple edentulous areas. Although RPDs have these advantages,they are well known for exacerbating plaque levels in individuals with less than oral hygiene. Although RPDs have these advantages, they are well known for exacerbating plaque levels in individuals with less than oral hygiene. In this review, the influence of xerostomia on pain sensitivity in oral mucosa of denture wearers is demonstrated. The aim of the study is to evaluate the association between oral dryness and oral pain sensitivity.
