Management of dry mouth in Sjögren's syndrome

Abstract

The management of dry mouth is essential for patients with Sjögren's syndrome. The symptomatic treatment has included using air humidifiers, rinsing the mouth with water or mouthwash, the application of a salivary substitute and administration of secretagogues. There are three secretagogues suitable for the alleviation of dry mouth in Sjögren's syndrome patients in Japan; cevimeline hydrochloride hydrate (cevimeline), pilocarpine hydrochloride, and anetholtrithione. A relationship between the effect of cevimeline on saliva secretion and the degree of salivary gland destruction evaluated by sialography and histopathological findings in the labial minor salivary glands has been reported. These diagnostic approaches could provide useful prognostic information on the efficacy of cevimeline in Sjögren's syndrome patients. Concomitantly, a bite guard was suggested as an effective lubricating device because it maintains the lubricants in the proper location. In addition, the management of the complications of dry mouth, such as tooth caries, periodontitis and oral candidiasis, which all lead to a reduction in the QOL, is also important. Both the prevention and treatment of erythematous candidiasis is especially important in the management of Sjögren's syndrome.
