Abstract
OBJECTIVE To investigate the associations between age, gender, systemic diseases, medications and labial and whole salivary flow rates in older people. METHODS Unstimulated labial (LS) and unstimulated (UWS) and chewing-stimulated (SWS) whole salivary flow rates were measured in 389 randomly selected community-dwelling Danish women and 279 men aged 65-97 years. Systemic diseases, medications (coded according to the Anatomical Therapeutic Chemical (ATC) Classification System), tobacco and alcohol consumption were registered. RESULTS The number of diseases and medications was higher and UWS lower in the older age groups. On average, women were slightly older, had more diseases, higher medication intake and lower UWS, SWS and LS than men. High number of diseases and medications was associated with low UWS, SWS and LS. In the healthy (14%) and nonmedicated (19%) participants, flow rates were not associated with age and gender, apart from SWS being lower in nonmedicated women. Low UWS were associated with psychiatric and respiratory disorders, type 2 diabetes and intake of psycholeptics, psychoanaleptics (especially SRRIs), respiratory agents, oral antidiabetics (particularly sulfonylureas), magnesium-hydroxide, cardiac agents, quinine, thiazides, calcium channel blockers, statins, urinary antispasmodics, glucosamine, NSAIDs, opioids and ophthalmologicals. SWS were lower in participants with ophthalmological disorders using ophthalmologicals (especially antiglaucoma agents and miotics), but also in those taking antidepressants, cardiac agents (mostly digitalis glycosides) and calcium channel blockers. Cardiovascular diseases and intake of anti-thrombotics (mainly low dose aspirins), calcium channel blockers and oral antidiabetics were associated with low LS. CONCLUSIONS In older people, low salivary flow rates are associated with specific and high number of diseases and medications, but neither with age and gender per se nor with tobacco and alcohol consumption. Low UWS are associated with more diseases and medications than SWS and LS, which were primarily associated with cardiovascular diseases and medications including preventive agents such as low-dose aspirins and statins. New insights into medications and their association with salivary gland function were achieved using the ATC classification system.

Abstract
Dysphagia clinicians are aware that best practices guidelines recommend a medications review as part of the assessment process. This article aims to review the literature to date regarding the impact that medications may have on the physiology of swallowing. It is important to consider the side effects of all medications, not only medications listing swallowing difficulties as a known side effect. Medications that impact upon arousal, awareness, and xerostomia should also be considered as part of a comprehensive dysphagia evaluation. Speech-language pathologists should consider the pharmacist an integral dysphagia team member and a valuable resource.

Abstract
Changes in the oral cavity, such as periodontitis and other manifestations of poor oral health, are common in patients with chronic kidney disease (CKD) and may contribute to increased morbidity and mortality because of systemic consequences such as inflammation, infections, protein-energy wasting, and atherosclerotic complications. Poor oral health in CKD patients may thus represent an important, but often overlooked, problem. Several studies show that uremic patients have higher rates of decayed, missing, and filled teeth, loss of attachment, and periapical and mucosal lesions than the general population. The consequences of poor oral health may be more severe in CKD patients because of advanced age, common comorbidities such as diabetes, concurrent medications, and a state of immune dysfunction that may increase the risk for systemic consequences of periodontitis and other oral and dental pathologic conditions. Poor dentition and other signs of poor oral health should be an alarm clock also at early stages of CKD. However, it remains to be determined whether more successful management of poor oral health and periodontitis will reduce the risk of inflammation, infection, protein-energy wasting, and atherosclerotic complications in CKD patients. This review explores etiological factors and potential systemic consequences of poor oral health in CKD patients as well as possible preventive and therapeutic strategies.

Abstract
OBJECTIVE To investigate the associations between age, gender, systemic diseases, medications, labial and whole salivary flow rates and oral and ocular dryness in older people. METHODS Symptoms of oral and ocular dryness, systemic diseases, medications (coded according to the Anatomical therapeutic chemical (ATC) classification system), tobacco and alcohol consumption were registered, and unstimulated labial (LS) and unstimulated (UWS) and chewing-stimulated (SWS) whole salivary flow rates were measured in 668 randomly selected community-dwelling elderly aged 65-95. RESULTS Presence of oral (12%) and ocular (11%) dryness was positively correlated. Oral dryness was associated with low UWS, SWS and LS, and ocular dryness with low UWS and SWS. Oral and ocular dryness was related to female gender, but not to age. Only four persons in the healthy and nonmedicated subgroups reported oral and ocular dryness. The numbers of diseases and medications were higher in the older age groups and associated with oral and ocular dryness, low UWS, SWS and LS. On average, women were slightly older, reported more oral and ocular dryness and had lower UWS, SWS, LS and higher numbers of diseases and medications. High prevalence and odds ratios for oral dryness were associated with metabolic, respiratory and neurological diseases and intake of thyroid hormones, respiratory agents (primarily glucocorticoids), psycholeptics and/or psychoanaleptics, antineoplastics, proton pump inhibitors, antidiabetics, loop diuretics, antispasmodics, quinine and bisphosphonates. Ocular dryness was especially associated with neurological diseases and intake of psycholeptics and/or psychoanaleptics. Intake of magnesium hydroxide, antithrombotics, cardiac agents, thiazides, beta-blockers, calcium channel blockers, ACE inhibitors/angiotensin II antagonists, statins, glucosamine, paracetamol/opioids, ophthalmologicals and certain combination therapies was related to oral and ocular dryness. CONCLUSIONS In older people, oral and ocular dryness are associated with low salivary flow rates, specific as well as high number of diseases and medications, but neither with age and gender per se nor with tobacco and alcohol consumption. New detailed information concerning associations between medications and oral and ocular dryness has been obtained using the ATC classification system.

Abstract
Taste and smell are critical components to a person's overall sense of well-being and quality of life. Taste related problems can cause pain and discomfort and can hinder the maintenance of a satisfying and nutritious diet. Loss of taste interferes with pleasure derived from food and food-related activities. Many drugs can affect this special sense and contribute significantly to the morbidity of the associated illness. This article gives a brief account of this problem and emphasizes the need for more awareness of the clinicians about this problem.

Abstract
Swallowing disorders (or dysphagia) are common in the elderly and their prevalence is often underestimated. They may result in serious complications including dehydration, malnutrition, airway obstruction, aspiration pneumonia (infectious process) or pneumonitis (chemical injury caused by the inhalation of sterile gastric contents). Moreover the repercussions of dysphagia are not only physical but also emotional and social, leading to depression, altered quality of life, and social isolation. While some changes in swallowing may be a natural result of aging, dysphagia in the elderly is mainly due to central nervous system diseases such as stroke, parkinsonism, dementia, medications, local oral and oesophageal factors. To be effective, management requires a multidisciplinary team approach and a careful assessment of the patient's oropharyngeal anatomy and physiology, medical and nutritional status, cognition, language and behaviour. Clinical evaluation can be completed by a videofluoroscopic study which enables observation of bolus movement and movements of the oral cavity, pharynx and larynx throughout the swallow. The treatment depends on the underlying cause, extent of dysphagia and prognosis. Various categories of treatment are available, including compensatory strategies (postural changes and dietary modification), direct or indirect therapy techniques (swallow manoeuvres, medication and surgical procedures).

Abstract
The impact of medications on the physiology of swallowing has received much attention in dysphagia literature. This article reviews the potential effects of medications commonly prescribed in an adult continuing care and rehabilitation facility on swallowing. An audit of medications prescribed to 153 adults accessing age-related respiratory, neurology, and learning disability services was performed. This was followed by an investigation of relevant sources to identify the potential side effects of these medications. One side effect, namely, xerostomia, which our investigations revealed could be a side effect of 24.8% of the medications used at our institution, was further investigated. The prevalence of xerostomia was then investigated in a randomly selected sample of ten subjects whose dysphagia had been confirmed by videofluoroscopy. It was found that six of the ten dysphagic clients displayed xerostomia. Review of the medications of these ten subjects indicated that all were using from three to nine drugs that could cause xerostomia. This article highlights the need for health-care professionals to consider the potential effects of these medications on swallowing and, indeed, the general presentation of clients.

Abstract
Background This study aimed to investigate the signs of oral dryness in relation to different salivary variables and to correlate subjective complaints of oral dryness with salivary flow rate. Methods 312 unmedicated healthy individuals belonging to three age groups, (6–11, 12–17, and 18–40 years) were examined clinically for signs of oral dryness. Resting and stimulated saliva were collected to determine flow rate, pH and buffering capacity. A questionnaire was used to obtain information on subjective sensation of dry mouth. Results Dry lip and dry mucosa were present in 37.5% and 3.2% of the sample respectively. The proportion of subjects who complained of oral dryness (19%) showed a stimulated salivary flow rate significantly lower than non complainers. Dry lip was significantly related to low resting flow rate but pH and buffering capacity did not show any significant relation to dry lip. Dry mucosa was not related to any of the above mentioned parameters. Conclusion The finding that the stimulated salivary flow rate was reduced in subjects complaining of dry mouth is of great clinical relevance, since the reduction is expected to be reflected in compromising various salivary functions.

Abstract
BACKGROUND The objective of this literature review is to summarize information about the etiology, diagnosis, oral sequelae and treatment of dry mouth in elderly patients. TYPES OF STUDIES REVIEWED The authors conducted a comprehensive review of the English-based scientific literature from the past 10 years. They selected the studies on the basis of clinical investigations to provide an objective assessment of dry mouth problems among older people. RESULTS Dry mouth (salivary hypofunction, xerostomia) is a common problem among older people. It causes significant oropharyngeal disorders, pain and an impaired quality of life. Dry mouth has many causes, from local salivary disorders to a plethora of medications and medical conditions. Treatments are designed to correct the underlying cause and/or to enhance salivation with topical and systemic stimulants. Early intervention for dry mouth problems helps prevent the deleterious consequences of this disorder in elderly people. CLINICAL IMPLICATIONS Clinicians must be aware of dry mouth problems in older patients, and they should be prepared to provide a diagnosis and administer treatment to protect a patient's oropharyngeal health and quality of life.

Abstract
OBJECTIVE To determine the association of hyposalivation and the perception of dry mouth with oral health-related quality of life for independently living elderly. STUDY DESIGN The study sample consisted of 287 participants (mean age, 66.1 years) at a Senior Citizen educational system. Stimulated salivary flow rates during chewing were measured. The OHIP-14 to measure the impact of oral conditions on health-related quality of life was used, and summary OHIP-14 scores combining the response codes for the 14 items were analyzed. RESULTS A logistic regression analysis showed that a higher OHIP-14 score indicating a poorer quality of life was related to fewer residual teeth, perception of dry mouth on eating (OR: 4.01, P = .012) and hyposalivation (OR: 2.71, P = .006). CONCLUSION It is suggested that both dry mouth and hyposalivation are important problems influencing the quality of life in independently living, relatively healthy elderly Japanese.

Abstract
The consequences of xerostomia on oral health have been studied for decades; however, the actual prevalence of this disorder on the general population remains controversial. The purpose of this systematic review was to determine the prevalence of xerostomia in population-based samples. Electronic databases were screened for relevant articles and reference lists of pertinent articles were also hand-searched. Thirteen articles meeting the final inclusion criteria were identified. Based on the definition of xerostomia used in this review, only publications including a subjective diagnosis of the disorder were included. All of the self-reported diagnoses were achieved through a questionnaire either by mail, telephone, interview or self-administered by the patient. There was a variation across papers regarding number and content of the questions as well as guidelines for the diagnosis of xerostomia (i.e. answer yes to one or more than one question). The prevalence of xerostomia in the selected articles ranged from 0.9% to 64.8%. The majority of these studies were performed in Scandinavia. In 9 of the articles, the studied samples were 50 years and older. None of the studies evaluated the prevalence xerostomia among individuals younger than 18 years. Based on these observations, it can be concluded that there is a need for population-based studies on prevalence of xerostomia in regions other than Scandinavia. A standardized protocol to diagnose xerostomia needs to be developed. Patient-perceived treatment needs and impact on quality of life should be included to have a complete picture of public health implications of the disease.

Abstract
The incidence, severity and tolerability of dry mouth was compared in 790 women with overactive bladder who were treated with extended-release oxybutynin chloride 10 mg/day or extended-release tolterodine tartrate 4 mg/day for 12 weeks in a multicenter, double-blind, parallel-group study. Dry mouth was the most common adverse event associated with treatment, with an incidence rate of 28.1% in the oxybutynin group and 21.6% in the tolterodine group (P = 0.039). The majority of dry mouth events were mild in both treatment groups. Severe dry mouth occurred in 1.5% and 0.5% of patients in the oxybutynin and tolterodine groups, respectively (P = 0.173). Seven patients on extended-release oxybutynin and 4 patients on extended-release tolterodine discontinued treatment due to dry mouth (P = 0.380). The results of this analysis showed that dry mouth was common with both treatments, but most events were mild; there was no difference in the rate of severe dry mouth or in the rate of withdrawal due to dry mouth.

Abstract
BACKGROUND Overactive bladder (OAB) syndrome is characterized by urinary frequency and urgency with or without urge incontinence, and often accompanied by nocturia. The prevalence of OAB increases with aging; it is a particularly common condition among the elderly, affecting at least 25% of people aged > or = 65 years. OBJECTIVE The goal of this study was to assess the efficacy and tolerability of solifenacin 5 and 10 mg once daily for treating elderly subjects with OAB. METHODS This was a retrospective analysis of pooled data from 4 studies. Data were analyzed from elderly subjects (aged > or = 65 years) with OAB who were treated with solifenacin in four 12-week, double-blind, Phase III, international, multicenter, randomized, parallel-group, fixed-dose, placebo-controlled studies and from elderly subjects who received solifenacin in a 40-week, open-label, flexible-dose extension trial that enrolled subjects who completed 2 of the double-blind studies. Micturition data were collected from diaries completed during the 3 days before each study visit. Efficacy end points included mean change from baseline for the number of incontinence episodes/24 hours, urgency episodes/24 hours, number of micturitions/24 hours, and volume voided/micturition. The proportion of subjects who became continent or had no urgency episodes at end point was also evaluated. RESULTS The mean age of the subjects in the 12-week, double-blind studies (N = 1045; 781 women, 264 men) was 71.9 years; mean age in the 40-week extension trial (N = 509; 359 women, 150 men) was 71.2 years. The majority of subjects (74.7% in the 12-week, double-blind studies and 70.5% in the 40-week extension trial) were female, and >90% of the elderly subjects were white. The duration of OAB ranged from 0 to 66 months, and 43.7% had received previous medical therapy for OAB. The completion rate for elderly subjects was 85.5% for the 12-week, double-blind studies and 80.0% for the 40-week extension trial. Efficacy end points at week 12 of double-blind treatment demonstrated statistically significant improvements in the symptoms of OAB with solifenacin compared with placebo. Mean (SE) changes in number of incontinence episodes/24 hours were -1.5 (0.17) for the 5-mg dose and -1.9 (0.14) for the 10-mg dose compared with -1.0 (0.14) for placebo (P = 0.013 for the 5-mg dose and P < 0.001 for the 10-mg dose, vs placebo); mean (SE) changes in the number of urgency episodes/24 hours were -3.2 (0.27) for the 5-mg dose and -3.2 (0.19) for the 10-mg dose compared with -1.6 (0.18) for placebo (P < 0.001 for both doses vs placebo); mean (SE) changes in the number of micturitions/24 hours were -2.0 (0.17) for the 5-mg dose and -2.5 (0.13) for the 10-mg dose compared with -1.1 (0.13) for placebo (P < 0.001 for both doses vs placebo); mean (SE) changes in the volume voided/micturition were 30.2 (3.24) mL for the 5-mg dose and 46.2 (2.55) mL for the 10-mg dose, compared with 9.1 (2.39) mL for placebo (P < 0.001 for both doses vs placebo). The proportion of subjects with restoration of continence was 49.1% and 47.3% of the 5- and 10-mg treatment groups, respectively, compared with 28.9% of the placebo group (P < 0.001 for both doses vs placebo). The proportion of subjects with resolution of urgency was 34.6% and 24.9% for the 5- and 10-mg treatment groups, respectively, compared with 16.9% of the placebo group (P < 0.001 for the 5-mg dose and P < 0.01 for the 10-mg dose). Improvements in incontinence, urgency, and micturitions were maintained during the 40-week extension trial. The most common adverse events in both the double-blind and extension trials were dry mouth, constipation, and urinary tract infection. Most adverse events were mild to moderate in nature and did not result in treatment discontinuation. CONCLUSIONS In these pooled analyses, solifenacin 5 and 10 mg once daily were efficacious and well tolerated in the treatment of these elderly subjects with OAB. Solifenacin therapy was also associated with a high level of persistence in a 40-week extension trial.

Abstract
OBJECTIVE The purpose of this study was to determine the association of dry mouth with oral symptoms and function, such as denture instability, discomfort, soreness in denture-bearing tissue, and dissatisfaction with chewing, tasting, or speaking in removable denture wearers. STUDY DESIGN The subjects were 493 removable denture wearers with a mean age of 67.3 years. Perception of oral dryness was measured by a questionnaire. A multiple logistic regression analysis was used to determine the effect of the dry mouth on oral symptoms and function after controlling for age and gender. RESULTS Oral dryness during eating was related to dissatisfaction with chewing (odds ratio, 10.5; P < .001) and speaking (odds ratio, 3.5; P < .05) and overall dissatisfaction (odds ratio, 6.3; P < .01) in complete denture wearers. Feeling of dry mouth was likely to be associated with soreness in denture-bearing tissues in both complete and removable partial denture wearers. CONCLUSIONS There was a significant association of the perception of dry mouth among a group of denture wearers with oral symptoms and function.

Abstract
OBJECTIVES This work consists in improving oral hygiene (OH) for elderly dependent people in long-term hospital care, in order to decrease the degree of colonization and the associated risk of developing oral candidiasis. As this population frequently suffers from such colonization and because it is difficult to install and practice OH care, a study protocol was designed at the request of geriatricians. The objective of the present study was to set up a programme of OH, applied by the care staff, and to monitor oral colonization of by Candida spp. BASIC RESEARCH DESIGN We compared the levels of hygiene and Candida spp. colonization for a group of 110 long-term patients in geriatric departments at T1, when clinical data were collected and oral mycological samples taken before the OH protocol was applied, and at T2, during the postprotocol phase after 3 months of application, when the clinical data and sample collection were repeated. RESULTS During these 3 months 11 patients died. These patients were excluded from the results, which are presented for matched series of the 99 patients still present at T2. Statistical analysis comparing the clinical and biological parameters at T1 and T2 established that there had been an improvement in OH: the 'adequate' level was reached for 72.4% of patients at T2 compared with 41.8% at T1 (P < 0.001) and the 'very inadequate' level was observed for 9.2% at T2 compared with 27.9% at T1 (P < 0.01). A reduction was observed in the number of patients showing the highest degree of C. albicans and C. glabrata colonization (> 50 colony forming units) from 41.9% at T1 to 24.9% at T2 (P < 0.05) and from 56.4% at T1 to 13.0% at T2 (P < 0.05) respectively. The number of patients with candidiasis fell significantly from 43.2% at T1 to 10.2% at T2. CONCLUSIONS The OH protocol led to an overall decrease in Candida spp. colonization, a significant reduction in the number of candidiasis and an improvement in the level of oral and denture hygiene but vigilance is still necessary concerning OH care and the initial training of staff in specific care of the mouth.

Abstract
Salivary gland hypofunction and complaints of xerostomia are common in elderly patients, irrespective of their living situation. Medication use is frequently related to dry mouth symptoms and reductions in salivary flow rates. Patients with reduced salivary flow are at increased risk for caries, oral fungal infections, swallowing problems, and diminished or altered taste. Oral health care providers should institute aggressive preventive measures and recommend palliative care for patients with significant reduction in salivary gland function. The systemic agents pilocarpine and cevimeline may help selected patients. Selective use of fluoride-releasing restorative materials and conservative treatment plans are recommended for this patient group.

Abstract
Dry mouth (xerostomia) is one of the most common complaints following radiation therapy (RT) for head and neck cancers. Notably, RT causes irreparable damage to salivary glands that increases the risk for severe and long-term oral and pharyngeal disorders. Several strategies in the treatment of head and neck cancers have been developed to prevent RT-induced salivary dysfunction while providing definitive oncologic therapy. These include salivary-sparing RT; cytoprotectants (such as amifostine); combination therapy of high-dose-rate intraoperative RT, external beam RT, plus a cytoprotectant; salivary gland surgical transfer; and gene therapy. Future research that incorporates biologic, pharmacologic, and technologic advancements that optimize therapeutic ratios and minimizes adverse oral sequelae is warranted.

Abstract
OBJECTIVES We have recently developed a new device for measuring the spinnbarkeit of saliva called the Neva Meter. The purpose of this study was to evaluate this device and to measure spinnbarkeit as well as viscosity, another important property, in the resting saliva of 24 healthy adults. METHODS We used polyvinyl alcohol (PVA) as a standard solution to establish the reproducibility of spinnbarkeit tests. We collected resting saliva from 24 employees of a business office (16 males and 8 females, average age: 37.8) and investigated the relationship between spinnbarkeit and viscosity. RESULTS The spinnbarkeit of PVA increased along with the concentration of the solution, and the reproducibility of the values was acceptable. Spinnbarkeit of resting saliva showed a positive correlation with viscosity at a shear rate of 76.6 s(-1) (r = 0.55, P < 0.05) and 191.5 s(-1) (r = 0.59, p < 0.05). CONCLUSIONS The newly developed Neva Meter was suitable for measuring the spinnbarkeit of saliva quickly and easily at the chair-side in the dental clinic. Results obtained using this new device may be important for understanding and evaluating the condition of the oral cavity.

Abstract
Xerostomia or dry mouth is a condition that is frequently encountered in dental practice. The most common cause is the use of certain systemic medications, which make the elderly at greater risk because they are usually more medicated. Other causes include high doses of radiation and certain diseases such as Sjogren's syndrome. Xerostomia is associated with difficulties in chewing, swallowing, tasting or speaking. This results in poor diet, malnutrition and decreased social interaction. Xerostomia can cause oral discomfort, especially for denture wearers. Patients are at increased risk of developing dental caries. A thorough intraoral and extra-oral clinical examination is important for diagnosis. Treatment may include the use of salivary substitutes (Biotene), salivary stimulants such as pilocarpine, ongoing dental care, caries prevention, a review of the current prescription drug regimen and possible elimination of drugs having anticholinergic effects. Because of the ageing population, and the concomitant increase in medicated individuals, dentists can expect to be presented with xerostomia in an increasing number of patients in the coming years and therefore should be familiar with its diagnosis and treatment. Therefore, the purpose of this review is to outline for clinicians the common aetiologies, clinical identification, and routine therapeutic modalities available for individuals with xerostomia.

Abstract
OBJECTIVE To identify drugs associated with the complaint of dry mouth. MATERIALS AND METHODS MEDLINE was searched for papers 1980-2002 using keywords, oral, mouth, salivary, drugs, dry mouth and xerostomia, and relevant secondary references were hand-searched. RESULTS Evidence was forthcoming for a number of xerogenic drugs, especially antimuscarinic agents, some sympathomimetic agents, and agents affecting serotonin and noradrenaline uptake, as well as a miscellany of other drugs such as appetite suppressants, protease inhibitors and cytokines. CONCLUSION Dry mouth has a variety of possible causes but drugs--especially those with anticholinergic activity against the M3 muscarinic receptor--are the most common cause of reduced salivation.

Abstract
BACKGROUND Dentists recognize the importance of saliva in maintaining oral health and often are familiar with the clinical effects an insufficient salivary flow can have on oral tissues. A variety of medical conditions and medications can alter salivary secretion and composition. Typically, diagnosis of hyposalivation is made only after damage has occurred to the oral tissues. OVERVIEW The author describes a series of clinical steps that, if followed properly, may help in the early detection of salivary gland hypofunction and prevention of its severe complications. This four-step approach includes identifying a patient's chief complaint and the symptoms and duration of illness that brought the patient to the dentist, as well as any approaches the patient took to relieve symptoms; obtaining a medical history that includes a review of the body systems; performing a clinical evaluation that notes the patient's overall condition in addition to the health and functioning of the salivary glands and oral soft and hard tissues; and, when needed, conducting further diagnostic evaluations. CONCLUSIONS AND CLINICAL IMPLICATIONS Oral health care providers will continue to face the challenges of treating new and recurrent carious lesions if the profession's approach to salivary hypofunction remains reactive rather than proactive. The recommendations in this article may enhance clinicians' awareness of the objective methods used to identify patients with salivary gland hypofunction or those at risk of developing it. It is hoped that early identification of asymptomatic patients at risk of developing hyposalivation, as well as symptomatic patients will lower the incidence and prevalence of dental caries and fungal infection in this population and ultimately enhance their quality of life.

Abstract
BACKGROUND Clinicians may encounter symptoms of xerostomia, commonly called "dry mouth," among patients who take medications, have certain connective tissue or immunological disorders or have been treated with radiation therapy. When xerostomia is the result of a reduction in salivary flow, significant oral complications can occur. TYPES OF STUDIES REVIEWED The authors conducted an Index Medicus--generated review of clinical and scientific reports of xerostomia in the dental and medical literature during the past 20 years. The literature pertaining to xerostomia represented the disciplines of oral medicine, pathology, pharmacology, epidemiology, gerodontology, dental oncology, immunology and rheumatology. Additional topics included the physiology of salivary function and the management of xerostomia and its complications. RESULTS Xerostomia often develops when the amount of saliva that bathes the oral mucous membranes is reduced. However, symptoms may occur without a measurable reduction in salivary gland output. The most frequently reported cause of xerostomia is the use of xerostomic medications. A number of commonly prescribed drugs with a variety of pharmacological activities have been found to produce xerostomia as a side effect. Additionally, xerostomia often is associated with Sjögren's syndrome, a condition that involves dry mouth and dry eyes and that may be accompanied by rheumatoid arthritis or a related connective tissue disease. Xerostomia also is a frequent complication of radiation therapy. CONCLUSIONS AND CLINICAL IMPLICATIONS Xerostomia is an uncomfortable condition and a common oral complaint for which patients may seek relief from dental practitioners. Complications of xerostomia include dental caries, candidiasis or difficulty with the use of dentures. The clinician needs to identify the possible cause(s) and provide the patient with appropriate treatment. Remedies for xerostomia usually are palliative but may offer some protection from the condition's more significant complications.

Abstract
OBJECTIVES To evaluate the efficacy, safety, and tolerability of a new, once-daily extended-release (ER) formulation of tolterodine in treating overactive bladder in older (> or =65) and younger (<65) patients. DESIGN A 12-week double-blind, placebo-controlled clinical trial. SETTING An international study conducted at 167 medical centers. PARTICIPANTS One thousand fifteen patients (43.1% aged > or =65) with urge incontinence and urinary frequency. INTERVENTION Patients were randomized to treatment with tolterodine ER 4 mg once daily (qd) (n = 507) or placebo (n = 508) for 12 weeks. MEASUREMENTS Efficacy, measured with micturition charts (incontinence episodes, micturitions, volume voided per micturition) and subjective patient assessments, safety, and tolerability endpoints were evaluated, relative to placebo, according to two age cohorts: younger than 65 and 65 and older. RESULTS Mean age in the older and younger patient cohorts was 74 (range 65-93) and 51 (range 20-64), respectively. Compared with placebo, significant improvements in micturition chart variables with tolterodine ER showed no age-related differences. Irrespective of age, significantly more tolterodine ER recipients than placebo recipients reported an improvement in urgency symptoms. After 12 weeks of treatment with tolterodine ER, a fivefold increase in the percentage of patients able to finish tasks before voiding in response to urgency was noted in both age groups (<65: from 6.5-32.8%, > or =65: from 5.1-26.2%). Tolterodine ER recipients, irrespective of age, also had significant improvements in their bladder condition than did placebo recipients. Overall, a greater percentage of patients, irrespective of age, perceived any benefit with tolterodine ER than with placebo (P <.001). Dry mouth (of any severity) was the most common adverse event in both the tolterodine ER and placebo treatment arms, irrespective of age (<65: ER 22.7%, placebo 8.1%; > or =65: ER 24.3%, placebo 7.2%). Few patients (<2%) experienced severe dry mouth. No central nervous system, visual, cardiac (per electrocardiogram), or laboratory safety concerns were noted. Withdrawal rates due to adverse events on tolterodine ER 4 mg qd were comparable in the two age cohorts (<65: 5.5%; > or =65: 5.1%; P =.87). CONCLUSIONS The new, once-daily ER formulation of tolterodine is efficacious, safe, and well tolerated in the treatment of patients with symptoms of overactive bladder, irrespective of age.

Abstract
Saliva has multiple essential functions in relation to the digestive process taking place in the upper parts of the gastrointestinal (GI) tract. This paper reviews the role of human saliva and its compositional elements in relation to the GI functions of taste, mastication, bolus formation, enzymatic digestion, and swallowing. The indirect function of saliva in the digestive process that includes maintenance of an intact dentition and mucosa is also reviewed. Finally, pathophysiological considerations of salivary dysfunction in relation to some GI functions are considered.

Abstract
Introdução: A xerostomia é uma queixa subjetiva que pode ou não estar relacionada à diminuição da salivação. Deve, porém, ser sempre investigada, pois está freqüentemente associada a doenças sistêmicas, incluindo a síndrome de Sjögren. Apesar de não haver padrão universal que caracterize a hipossalivação, consideramos a sialometria importante para avaliação do tratamento, através da realização de exames seriados em um mesmo paciente. Analisando as técnicas de sialometria já descritas, optamos por adaptar e padronizar o método de Bolwig e Rafaelsen (1972) por considerá-lo o mais prático e fidedigno e visando à partir de então a sua utilização em larga escala. Objetivo: Avaliar os resultados de método submúltiplo de sialometria. Material e método: Foram avaliados 10 sujeitos, 5 sem sintomatologia de xerostomia que formam considerados compatíveis e 5 com xerostomia. Foram submetidos ao método de sialometria com algodão pré e pós estimulados. Os resultados foram comprovados. Resultados: Todos os pacientes apresentaram melhora da saliva mensurável pelo método pós-estimulado. Conclusões: O método utilizado se mostrou de fácil realização e fidedigno.

Abstract
Saliva is essential for the preservation of oral-pharyngeal health, and disorders of salivary physiology are associated with numerous oral and pharyngeal problems, particularly in older people. Although salivary function is remarkably intact in healthy aging, medical problems, medications, and head and neck radiotherapy can cause salivary dysfunction and complaints of xerostomia among older people. Sjögren's syndrome, an autoimmune exocrinopathy, is the most common medical disease associated with salivary dysfunction. Medications with anticholinergic side effects will impair salivary output, and head and neck radiotherapy for cancer will cause permanent destruction of salivary glands. Treatments for salivary problems are based upon establishing a diagnosis, protecting oral and pharyngeal health, stimulating remaining glands, and replacing lost salivary fluids.

Abstract
Overactive bladder (OAB) is a chronic condition that often requires long-term treatment to maintain control of symptoms. A range of therapeutic options are available; however, antimuscarinic agents form the mainstay of treatment. Of these agents, tolterodine and oxybutynin are the most widely used. It is well documented that the immediate-release (IR) formulations of these agents have equivalent efficacy in relieving OAB symptoms. However, tolterodine demonstrates a more favorable tolerability profile, particularly in terms of the frequency and severity of dry mouth. Due to the development of novel drug delivery systems, extended-release (ER) formulations of both oxybutynin and tolterodine are now available, permitting once-daily dosing. The convenience of once-daily dosing of antimuscarinic agents would be expected to improve patient compliance and further relieve the symptoms of OAB. Clinical studies with the ER formulations of tolterodine and oxybutynin demonstrate potential clinical advantages over their respective IR forms in terms of either efficacy or tolerability or both, although the therapeutic index of tolterodine ER appears to show a greater advantage over its IR counterpart compared with oxybutynin ER and its IR form. Importantly, the two ER agents have not been compared directly in a head-to-head clinical study. Overall, available clinical data suggest that the newly developed ER formulation of tolterodine represents a significant therapeutic advancement in the treatment of OAB.

Abstract
Reduced chewing function in community-dwelling older people with adequate general health is linked to having fewer than 20 teeth present or to wearing removable dentures. By chewing for longer periods of time or swallowing larger food particles they are normally able to compensate for the impaired function. The masticatory function can be restored by adequate prosthetic therapy, which results in increased activity of the masticatory muscles during chewing and reduces the chewing time and the number of chewing strokes until swallowing. In frail or dependent elderly people undernutrition is prevalent because of health problems, reduced appetite and poor quality of life. Poor oral health and xerostomia are often associated with a reduced body mass index and serum albumin level and the avoidance of difficult-to-chew foods. Maintenance or re-establishment of masticatory function is an integral part of the medical health care of these patients, with the aim of improving their nutritional status and quality of life.

Abstract
OBJECTIVE The purpose of this study was to investigate the prevalence of self-reported symptoms of dry mouth and burning mouth in the frail elderly. We expected to find the studied symptoms more frequently in the frail elderly than in those who were healthier. STUDY DESIGN We examined 175 home-living elderly patients (mean age with SD, 82 +/- 5.7 years) hospitalized because of sudden worsening of their general health. For comparison, 252 elderly outpatients (mean age with SD, 77 +/- 5.7 years) from the same community were studied. The subjects' medical diagnoses and prescribed drugs used daily were recorded, their oral health examined, and saliva samples taken for analyses of flow rates, yeasts, and a variety of biochemical factors. RESULTS The results showed that 63% of the hospitalized patients and 57% of the outpatients complained of dry mouth. The respective percentages of burning mouth were 13% in the hospitalized and 18% in the outpatients. The dentate status affected the feeling of dry mouth and burning mouth, but there were no consequent differences in concentrations of salivary biochemical constituents, yeast counts, and buffering capacity between patients with or without the symptoms except that hospitalized patients complaining of dry mouth more often had low salivary buffering than those without the symptom. Dry mouth was also more prevalent among the hospitalized patients who used several drugs daily, whereas no such association was found with the burning-mouth symptom. Use of analgesics appeared to safeguard against both the symptoms. Dry mouth and burning mouth were seldom reported simultaneously, although low salivary flow rate was a common finding in patients with burning mouth. The strongest explanatory factors for burning mouth were psychiatric disease among the outpatients (OR 8.7, CI 1.4-54.1, P <.05) and use of psychiatric drugs among the hospitalized (OR 4.2, CI 0.9-20.0, P =.07). For dry mouth, the strongest explanatory factors were respiratory disease in the outpatients (OR 2.0, CI 1.0-3.8, P <.05) and low salivary flow rate in the hospitalized elderly (OR 3.7, CI 1.4-10, P <.05). In all patients (n = 427), use of psychiatric drugs was the strongest explanatory factor for dry mouth (OR 2.1, CI 1.2-3.5, P <.01), whereas analgesic medication was found to protect against burning mouth (OR 0.5, CI 0.3-0.9, P <.05). CONCLUSION The subjective feelings of dry mouth and burning mouth appeared to be a complex issue among the elderly population studied. The 2 symptoms were seldom reported at the same time. The appearance of symptoms did not directly correlate with general health, except in the case of psychiatric diseases and medications, which should be taken into account.

Abstract
The aim of this study was to describe the relationships between the rate of tooth demineralisation and medication intake, subjective feeling of dry mouth, saliva flow, saliva composition and the salivary level of lactobacilli. The study group consisted of 28 subjects that were divided into three groups according to their unstimulated whole saliva flow rate. Group 1 had an unstimulated saliva low rate < or =0.16 ml/min (n=10), group 2 had one from 0.17--0.30 ml/min (n=9), and group 3 had one >0.30 ml/min (n=9). The rate of tooth demineralization was determined as mineral loss assessed by quantitative microradiography of human root surfaces, exposed to the oral environment for 62 days in situ. The unstimulated and stimulated saliva flow rates, pH, bicarbonate, calcium, phosphate, and protein concentrations, as well as the degree of saturation of saliva with hydroxyapatite and the saliva buffer capacity were determined. The results showed that almost all subjects developed demineralization, albeit at highly varying rates. Eighty-five percent of the subjects in group 1, 33% of the subjects in group 2, and 0% of the subjects in group 3 developed mineral loss above the mean mineral loss for all the root surfaces in this experiment. Futhermore, group 1 differed significantly from groups 2 and 3 in having a higher medication intake, a more pronounced feeling of dry mouth, lower stimulated saliva flow rate, lower stimulated bicarbonate concentration, lower unstimulated and stimulated compositional outputs (bicarbonate, calcium, phosphate, and protein), and a higher Lactobacillus level. The best explanatory variable for high mineral loss in this study was a low unstimulated saliva flow rate. In conclusion, our results suggest that an unstimulated salivary flow rate < or =0.16 ml/min as described by Navazesh et al. (1992), is a better indicator of increased caries risk due to impaired salivation, than the currently accepted definition of hyposalivation (unstimulated saliva flow rate < or =0.10 ml/min), which relates to the function of the salivary glands (Sreebny, 1992).

Abstract
Reduced chewing ability in community-dwelling older people is linked to the presence of removable dentures and having fewer than 20 natural teeth present. Compensation is provided by chewing longer and swallowing larger food particles. Replacement of posterior tooth loss by fixed or removable prostheses increases the activity of the masticatory muscles, and reduces chewing time and the number of chewing strokes until swallowing. In residents of nursing homes and long-term care facilities undernutrition is prevalent because of general medical problems, reduced appetite, and poor quality of life. Poor oral health and xerostomia are often present and may have a negative effect on masticatory function and nutrition, precipitating avoidance of difficult-to-chew foods. There is no evidence that the provision of prosthetic therapies can markedly improve dietary intakes; however, it might improve oral comfort and quality of life and avoid enteral alimentation.

Abstract
The purpose of this study was to examine the prevalence of perceived dry mouth among a group of independently-living elderly persons in Japan, and to determine its association with general disease, medication, and dental status, as well as its effect on oral function. The study population consisted of participants of the Senior Citizens' College. The subjective sensations of oral dryness on waking and while eating a meal were measured by a questionnaire. The number of usable questionnaires was 1003 or 77.9%. The mean age of the subjects was 66.3 +/- 4.2 years, and 53.0% were male. More than one-third (37.8%) of the subjects reported oral dryness on waking. Only 9.1% of them noticed a subjective feeling of dry mouth during eating. Persons who had at least one of these symptoms made up 41.0%. A multiple stepwise logistic regression analysis indicated the following results: Perception of dry mouth on waking was more frequent among males (p < 0.001), persons who had a low BMI (p < 0.05), and those taking two or more prescribed drugs (p < 0.01). Sensation of dry mouth when eating was more frequent among subjects with a low BMI (p < 0.001) and those who wore a denture in the maxillary arch (p < 0.05). Perception of dry mouth when eating was associated with self-assessed chewing ability (p < 0.01) and dissatisfaction with speaking clearly (p < 0.05), as well as dental status. However, dissatisfaction with tasting a meal had a significant relationship with the reports of mouth dryness on waking (p < 0.01). Our findings suggest that a substantially higher percentage of persons have the perception of dry mouth on waking than when eating, which was associated with medications, being male, and having a low BMI. This perception may influence oral function, especially the reported dissatisfaction with tasting foods.

Abstract
Dry mouth must not be considered a trivial problem in the population, since it constitutes a phenomenon with many aspects relative to oral function as well as quality of life. Up until today, no global consensus has been reached with regard to the terminology of dry mouth, creating a substantial problem for research, education, diagnosis, and therapy. In this report, salivary gland hypofunction has been selected as the overarching term for subjective symptoms and objective signs of dry mouth. Its different aspects--xerostomia, hyposalivation, and altered saliva composition--are reviewed with respect to prevalence, diagnosis, and etiology. It is concluded that these aspects of salivary gland hypofunction are separate entities, which in many respects are interrelated, constituting not merely a dental but also a medical and social concern.

Abstract
Salivary hypofunction is associated with oral and pharyngeal disorders and requires early diagnosis and intervention. Large variability in salivary flow rates within and between individuals has been reported, which has impaired the establishment of standard values. The objective of this study was to determine variations in stimulated parotid and submandibular flow rates over 6 hours and to define salivary hypofunction. Pooled mean, standard deviation, and coefficient of variation values for four collection time periods were obtained from 36 healthy males and females (18 young, ages 20-38; 18 older, ages 60-77). The results demonstrated 27-44% variation in salivary flow rates over time. Overall, there were no significant age or gender differences in variability between and within salivary flow rates at all collection time periods. The results suggest that a 45% range in salivary flow rates could be considered normal salivary variation, and values below 45% of normal levels could be used to define salivary hypofunction.

Abstract
OBJECTIVES The aim of this study was to examine the association between medication exposure and (1) unstimulated whole-salivary flow rate and (2) the severity of xerostomia among older people while adjusting for multiple medication use. METHODS Data were obtained from participants remaining at the five-year follow-up phase of a cohort study of community-dwelling older South Australians. Medication exposure information was available at baseline and at five years, enabling examination of the effects on dry mouth of long-term exposure to medications. At the five-year follow-up, unstimulated salivary flow was estimated using the spit method, and xerostomia severity was estimated using the 11-item Xerostomia Inventory. Because of the potential difficulties posed by polypharmacy, a two-stage analytical approach was employed: (1) Classification and Regression Tree (CART) analysis was used as an exploratory device to elucidate the relationships among the dependent and independent variables, and (2) linear regression analysis was used as a complementary procedure. RESULTS Unstimulated flow rate was lower among individuals who were female or taking antidepressants at both baseline and five years, and higher among smokers or people who were taking hypolipidemic drugs. Xerostomia severity was higher among females, or individuals taking: (1) an anginal at baseline and five years, (2) an anginal without a concomitant betablocker at five years, (3) thyroxine and a diuretic at five years, or (4) antidepressants or antiasthma drugs at both baseline and at five years. CONCLUSIONS These results suggest that polypharmacy can be accounted for to a certain extent by using CART analysis in conjunction with more conventional approaches; and that the relationship between medications and dry mouth is a complex one, and differs according to which aspect of dry mouth is being examined.

Abstract
Xerostomia and salivary gland hypofunction (SGH) are prevalent in elderly populations, causing much discomfort and even difficulties in eating. SGH also increases the occurrence and severity of oral diseases and makes the patient susceptible to candidiasis. The principal causes of SGH and xerostomia are systemic diseases and drugs used daily. The diagnosis of SGH and xerostomia is based on simple methods, of which measuring both unstimulated and stimulated salivary flow rate is the most important. Treatment calls for proper management of underlying disease, avoidance of all unnecessary medications, and topical remedies such as artificial saliva substitutes. However, good hydration is essential in the elderly with SGH and xerostomia, and water is the drink of choice. In extremely difficult cases, for instance in patients receiving radiotherapy for cancer of the head and neck regions, parasympathomimetic drugs may be administered if no contraindications exist.
