1/5. xerostomia: a prevalent condition in the elderly.Although xerostomia is associated with aging, studies have determined that salivary gland function is well preserved in the healthy geriatric population. Therefore, dry mouth is probably not a condition of aging, but most likely one of systemic or extrinsic origin. Saliva seems to undergo chemical changes with aging. As the amount of ptyalin decreases and mucin increases, saliva can become thick and viscous and present problems for the elderly. One of the most prevalent causes of xerostomia is medication. Anticholinergics, such as psychotropic agents and antihistamines, and diuretics can dry the oral mucosa. Chronic mouth breathing, radiation therapy, dehydration, and autoimmune diseases, such as Sjogren's, can also diminish salivation, as can systemic illness such as diabetes mellitus, nephritis, and thyroid dysfunction. xerostomia can lead to dysgeusia, glossodynia, sialadenitis, cracking and fissuring of the oral mucosa, and halitosis. Oral dryness can affect denture retention, mastication, and swallowing. Dry mouth symptom can be treated with hydration and sialagogues or with artificial saliva substitutes. Because patients are at risk for dental caries, they should be referred to a dentist for preventive care. In patients with sjogren's syndrome and in those who have undergone radiation therapy, pilocarpine has been used recently with good results.- - - - - - - - - - ranking = 1keywords = dysgeusia (Clic here for more details about this article) |
2/5. Factors contributing to adverse soft tissue reactions due to the use of tartar control toothpastes: report of a case and literature review.Tetrasodium and/or tetrapotassium pyrophosphate (Ppi) is the anticalculus component of most tartar control dentifrices on the market today. While pyrophosphates alone are not responsible for hypersensitivity reactions, several modifications which may lead to adverse oral manifestations may occur when pyrophosphates are added to a dentifrice. First, tetrasodium pyrophosphate in a dentifrice forms a slightly alkaline solution upon oral use which could irritate oral membranes. Second, increased concentrations of flavoring agents, known to be sensitizers, are needed to mask the strong bitter taste of pyrophosphates. Third, increased concentrations of detergents, capable of producing hypersensitivity reactions, are necessary to allow the pyrophosphates to become soluble in the dentifrice. Fourth, a pre-existing condition of reduced salivary flow may augment hypersensitivity to tartar control toothpastes. While pyrophosphates have been approved as additives in dentifrices, these compounds along with the increased concentrations of flavorings and detergents and their higher intraoral alkalinity are strongly implicated as the causative factor in certain hypersensitivity reactions.- - - - - - - - - - ranking = 0.24436858038994keywords = taste (Clic here for more details about this article) |
3/5. Secretory function of the salivary gland in patients with taste disorders or xerostomia: correlation with zinc deficiency.A notable proportion of patients with taste disorders complain of xerostomia and when zinc is prescribed the xerostomia is often improved in conjunction with the taste disorder. To study the relationship between taste disorders, zinc deficiency and xerostomia, we measured salivary gland function and zinc levels in 93 patients with hypogeusia and/or xerostomia and 60 patients with unilateral acute peripheral facial palsy who served as controls. We then prescribed zinc for patients with low serum zinc levels and evaluated xerostomia and taste sensation after 6 months of this treatment. The salivary gland secretory ratio (SGSR), determined by dynamic salivary 99mTc scintigraphy, was found to be an objective measure of salivary gland function and was reduced in patients with xerostomia. patients with salivary gland dysfunction also had abnormal morphology of the papillae of the tongue. No significant relation was found between the severity of taste disorders and SGSR values, but low SGSR values were found in patients with zinc deficiency. patients with taste disorders and/or xerostomia who were treated with zinc had relief of symptoms at 6 months, indicating that both taste disorders and xerostomia are among the symptoms of zinc deficiency.- - - - - - - - - - ranking = 2.6880543842893keywords = taste (Clic here for more details about this article) |
4/5. diagnosis of systemic sarcoidosis prompted by orofacial manifestations: a review of the literature.BACKGROUND: sarcoidosis is a multifactorial systemic inflammatory disorder of unknown origin characterized by many potential signs and symptoms, as well as by the presence of noncaseating granulomas in the organs involved. sarcoidosis also may manifest in the oral and maxillofacial region. CASE DESCRIPTION: The authors describe a patient with xerostomia, dysgeusia, oral burning, xerophthalmia and bilateral parotid enlargement. She was diagnosed as having systemic sarcoidosis on the basis of the histologic findings of a biopsy of the labial minor salivary gland, as well as subsequent diagnostic evalutons. CONCLUSION AND CLINICAL IMPLICATIONS: Enlargement of major salivary glands may be the first sign of sarcoidosis in a patient with few other symptoms or clinical findings suggestive of the disease. This case emphasizes the importance of including sarcoidosis in the differential diagnosis of bilateral parotid swelling associated with xerostomia. It also highlights the dentist's potential role in the diagnosis and dental treatment of patients with systemic sarcoidosis.- - - - - - - - - - ranking = 1keywords = dysgeusia (Clic here for more details about this article) |
5/5. An unusual presentation of chronic graft-versus-host disease in an unrelated bone marrow transplantation.The case described is that of an unrelated bone marrow transplantation in a 43-year-old man. Although the major histocompatibility complex met the criteria for a perfect genotypic match, de novo graft-versus-host disease developed with unusual manifestations involving structures of the oral cavity and associated areas. The loss of taste and smell, as well as profound xerostomia, was treated by stimulating salivary flow. Synergistic sialagogues were used with the hope that an increase in salivary production would mediate an improvement in taste and smell.- - - - - - - - - - ranking = 0.48873716077988keywords = taste (Clic here for more details about this article) |
