Self-reported dry mouth among ageing people: a longitudinal, cross-national study.

Focusing on Swedish and Norwegian cohorts of community-dwelling older adults between age 65 and 70, this study aimed to identify predictors of the prevalence and incident cases of daytime and night-time xerostomia. It was hypothesized that the prevalence increases with increasing age and is higher in women than in men and that the prevalence of persistent xerostomia and the 5-yr-incident cases are higher in people with consistent use of medication and need for health care. Of the Norwegian participants who completed the 2007 survey (age 65 yr), 70% (n = 2,947) participated in 2012. Individuals participating in both 2007 and 2012 constituted the Swedish panel (80%, n = 4,862). The prevalence of xerostomia was higher in women than in men and increased from age 65 to age 70, most markedly in the Swedish cohort. The risk of persistent xerostomia was greatest for participants with consistent use of medication (OR = 1.3) and contact with a physician (OR = 2.3). The risk of incident cases of xerostomia during daytime was greatest for participants with recent and consistent use of medication and recent contact with a physician. Dental professionals should identify patients with xerostomia, emphasize early prevention, and alleviate oral symptoms in collaboration with physicians.

The efficacy of cevimeline hydrochloride in the treatment of xerostomia in Sjögren's syndrome in southern Chinese patients: a randomised double-blind, placebo-controlled crossover study.

Cevimeline hydrochloride, a specific agonist of the M3 muscarinic receptor, is beneficial in the treatment of symptoms of xerostomia and xerophthalmia associated with Sjögren's syndrome (SS). Cevimeline has not been evaluated in southern Chinese patients. Furthermore, the effects of cevimeline on health-related quality of life and oral health status are not known. In this randomised, double-blind, placebo-controlled crossover study, patients received cevimeline 30 mg or matched placebo three times per day over 10 weeks followed by a 4-week washout period before treatment crossover. Participants self-completed the following questionnaires: Xerostomia Inventory (XI), the General Oral Health Assessment Index (GOHAI), the Ocular Surface Disease Index (OSDI) and the Medical Outcomes Short Form (SF-36). Clinical assessments included sialometry, examination of the oral cavity for the degree of xerostomia and dental complications of xerostomia. Fifty patients (22 primary SS and 28 secondary SS) were enrolled in the trial. Forty-four patients completed the study. There was a significant improvement in the XI and GOHAI scores as well as the objective rating of xerostomic signs of the oral cavity after treatment with cevimeline. However, there was no improvement in salivary flow rates and dry eye symptoms. SS patients had lower SF-36 scores, but these did not improve after treatment with cevimeline.

Oral health and medical status in dentate low-income older persons.

Oral and medical conditions of 295 low-income dentate older persons (17% African-Americans, 14.5% Asians, 11.5% Hispanics, and 57% Caucasians) were studied. The mean age was 72 (SD +/- 6.8; range, 60-91). Oral examinations were performed, stimulated saliva was collected, and interviews were conducted regarding oral health attitudes, knowledge, and behaviors. Past history of restorative care, defined by filled coronal surfaces, differed by ethnicity, with Caucasian elders having most filled surfaces (p < 0.001). Ethnic minority elders had significantly poorer periodontal health (p < 0.001), with the worst conditions in Asians. Low salivary flow (< 0.01 mL/min) was found in 31% using medications known to cause hyposalivation. Frequent diseases were arthritis (46%), hypertension (39%), heart disease (25.2%), and diabetes (8.5%). Hypothyroidism was associated with low flow rate (F = 13.2, p < 0.0003). Seventy percent reported that they had never smoked. Smokers had deeper probing depths (chi 2 = 11.98, p < 0.05) and more gingival recession (F = 8.08, p < 0.001). Women on hormone replacement therapy (HRT) had less calculus (F = 11.33, p < 0.01) and fewer sites with probing depths > 5 mm (F = 8.99, p < 0.003). The present study found few associations between physical and oral health and ethnicity. The benefits of HRT for women's periodontal health and the effects of hypothyroidism on stimulated salivary flow are noteworthy.

[The natural course of primary Sjögren's syndrome (a clinical study)]. / Estestvennoe techenie pervichnogo sindroma Shegrena (klinicheskoe issledovanie).

In this work the authors analyzed the clinical course and diagnostic procedures of 104 patients with primary Sjogren's syndrome (pSS): 57 patients diagnosed and followed-up at Ioannina University and 47 similar patients treated at the National Institute of Health (USA). Both studies have shown that pSS is predominantly a female disease with a latent period of 6-8 yrs from the time of the first symptom to the time of final diagnosis. Although the syndrome begins almost exclusively with glandular manifestations (xerostomia, xerophthalmia or parotid gland enlargement), in a respectable percentage of patients it eventually progresses to extraglandular involvement. pSS can be potentially complicated by benign (pseudolymphoma) or malignant (lymphoma) lymphoproliferative disorders.

Oral manifestations of HIV infection in a group of predominantly ethnic Chinese.

A total of 32 HIV-infected, predominantly ethnic Chinese individuals from Hong Kong were examined for oral mucosal lesions over a period of 1 year. The commonest oral lesion found was minor aphthous ulceration (27.4%), while xerostomia (17.8%), ulceration NOS (not otherwise specified; 12.3%), hairy leukoplakia (11.0%) and erythematous candidiasis (6.9%) were less frequent; Kaposi's sarcoma was notable for its absence. When the relationship between the number of oral lesions with age, risk group, medication taken, CDC staging and CD4+ count of the study group was investigated, a significantly higher number of oral lesions was associated with use of AZT, homosexuals and CDC stage IV; in contrast, a smaller number of lesions was found in those on antiparasitics and multivitamins (all P<0.05). When compared with studies from other parts of the world, the frequency of oral lesions appeared to be less common in the current study group. However, due to a lack of similar studies from the Asian region, especially in ethnic Chinese, it is not clear whether this difference could be attributed to racial, social or geographic factors.
