The aim of the study was to evaluate the prevalence of subjective perception of dry mouth in an adult population and to determine the prevalence of pharmacotherapy in this population. An additional aim was to assess a possible co-morbidity between symptoms of dry mouth and continuing pharmacotherapy. Four-thousand-two-hundred persons were selected at random from the national census register of the adult population of the southern part of the province of Halland, Sweden. The sample was stratified according to age and sex, and 300 men and an equal number of women aged 20, 30, 40, 50, 60, 70 and 80, were included. A newly developed questionnaire was mailed to each individual. In addition to questions about subjective perception of dry mouth, the subjects were asked to report on present diseases and continuing pharmacotherapy. Three-thousand-three-hundred and thirteen (80.5%) evaluable questionnaires were returned. The estimated prevalence of xerostomia in the population was 21.3% and 27.3% for men and women, respectively. This difference between the sexes was statistically significant. In non-medicated subjects, women tended to report a higher prevalence of xerostomia compared with men, 18.8% vs. 14.6%, and also among medicated subjects the estimated prevalence of dry mouth was higher for women than for men, 32.5% vs. 28.4%. There was a strong association between xerostomia and increasing age and also between xerostomia and continuing pharmacotherapy. The average prevalence of dry mouth among medicated and non-medicated subjects was 32.1% and 16.9%, respectively, the difference being statistically significant. There was also a strong association between xerostomia and the number of medications. In a logistic regression, the probability of reporting mouth dryness was significantly greater in older subjects and in women, and the probability increased with the number of medications taken. In conclusion, this epidemiological survey of an adult population has demonstrated that women, independent of age, do report a higher prevalence of xerostomia than men and that the symptom of dry mouth is strongly associated with age and pharmacotherapy. It is, however, not possible to discriminate between disease and pharmacotherapy as causal factors.

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.

The aim of this study was to evaluate the caries incidence in a group of young patients with type 1 diabetes mellitus over a 3-year period from the onset of the disease in relation to metabolic control and to caries-associated risk factors. Sixty-four children and adolescents (8–15 years of age) had their diabetes treated and monitored according to a standard medical protocol and received extensive preventive oral health care based on individual needs. Data on blood glucose and glycosylated haemoglobin (Hb A_Ic) were collected from the medical records. Whole saliva was collected every 3rd month and secretion rate, buffer capacity, glucose concentration, mutans streptococci and lactobacilli counts were determined. Dental examinations, including radiographs, were carried out once a year. Patients with less good metabolic control (>8.0% Hb A_Ic) exhibited higher glucose levels in resting saliva (p < 0.05) and a significantly higher caries incidence (p < 0.05) compared to those with good metabolic control. The most influential determinants for high caries development during the 3-year follow-up period were metabolic control (odds ratio, OR = 5.7), poor oral hygiene (OR = 6.5), previous caries experience (OR = 5.3) and high levels of salivary lactobacilli (OR = 5.0). The findings suggest that the level of metabolic control and traditional caries risk markers are important factors for caries development in children and adolescents with type 1 diabetes mellitus.

The aim of this study was to evaluate the influence of an oral health education program (OHEP) on attitudes among the responsible nursing personnel toward performing oral health procedures for care receivers. A total of 2882 nursing personnel were offered participation in the OHEP, and the effect was evaluated by means of a questionnaire distributed pre-educationally as well as 1-2 months post-educationally. The nursing personnel were allocated, on the basis of nursing education, to either a "high level of health care education" group (HHCE), including registered and enrolled nurses, or a "low level of health care education" group (LHCE), including nursing assistants and home care aides. Statistical analysis was performed by means of descriptive and analytical statistics. After the OHEP, the nursing personnel estimated their ability to perform oral hygiene procedures for care receivers to be significantly increased. Post-educationally, a significant shift in importance was observed from knowledge regarding the diseased oral cavity to knowledge regarding the healthy oral cavity. It was also observed that, in the LHCE group, the OHEP favored practical procedures, while in the HHCE group, theoretical considerations were favored. This indicates that, when oral health education programs are designed, due attention should be paid to the nursing personnel's education level.
