  • Patent number: 5541165
    Abstract: A saliva substitute composition includes glycerin, gum, water, and a pH buffering system. Sweeteners, colorants, and preservatives may be optionally combined. The glycerin component serves both as a lubricant and as a delivery vehicle for water from the composition to moisten the mouth. The gum component provides further lubrication and serves a water retention function. Gum arabic, xanthum, or sorghum are examples. The pH buffering system includes acidic and basic components. Citric acid or citrate salts and carbonate was found to be an effective buffering system. The composition is used to maintain moisture in the mouth when little or no natural saliva is produced, providing relief from dry mouth, as a symptom of xerostomia, mucositis, and stomatitis, as well as general inflammation and/or ulceration of mucous membranes, while avoiding pH imbalances which may lead to tooth decay and/or injury to the upper digestive tract including the oral cavity, oropharynx, or esophagus.
