Salivary Replacement Therapy/Salivary Stimulation- 1
When clients exhibit chronic and/or severe xerostomia, symptomatic relief of dry mouth and dry throat may be obtained by using salivary replacement therapy. For most clients, the natural alternative to saliva is water due to its low cost, ease of use and availability. Clients should be encouraged to drink frequently to remain hydrated, and to keep water at their bedsides for relief from nocturnal dryness. However, water is not an adequate saliva substitute, as it lacks the protective physical properties of saliva. Artificial salivary substitutes should be considered.
Most artificial salivas are comprised of sodium carboxymethyl-cellulose, to simulate natural viscosity and improve oral retention; flavoring agents, such as sorbitol and xylitol, for improved taste: and parabens, to inhibit bacterial growth.24, 25 Some of these agents also contain fluoride and electrolytes for added dental caries protection. Clients who are allergic to para-aminobenzoic acid or its derivatives, such as ester anesthetics, should not use products that contain parabens. For the general population, salivary substitutes are very safe to use, and may be used as often as needed throughout the day. Long-term compliance may be problematic because of the need for frequent dosing, the inconvenience of carrying these products, and cost.
