Level of education and incidence of caries in the elderly: a 5-year follow-up study

Objective: This study aimed to examine the possible association between level of education and 5‐year caries increment in the elderly inhabitants of Helsinki. Background: Low salivary flow and high numbers of salivary microorganisms are associated with the presence of caries, but cannot predict the increment in caries in the elderly. Materials and methods: This study group was derived from a population‐based Helsinki Aging Study, which consisted of a random sample of elderly born in 1904, 1909 and 1914. The 71 dentate elderly who underwent clinical oral examinations at baseline (1990–91) and 5 years later (1995–96) were included in the study group. Decayed, Missing or Filled Tooth (DMFT) and Root Caries Index (RCI) indexes were used to study subject’ caries experience. Data on subjects’ education came from questionnaire studies. The subjects were divided into four groups according to their level of education and occupation. Bivariate and multivariate analyses were used to evaluate relationships between subjects’ caries experience and level of education. Results: At baseline the elderly with high level of education had more teeth and more root surfaces at risk than those with low level of education. Number of teeth decreased (?1.085, p < 0.0001), while both DMFT (1.164, p < 0.0001) and RCI (0.081, p < 0.0001) indices increased during follow‐up. The increments in DMFT and RCI were not directly associated with the level of education. Multivariate analysis in which subjects’ gender, number of teeth, level of education, frequency of eating and frequency of brushing were taken into consideration, showed no significant association with caries increment. Conclusions: Within the limitations of this study it can be concluded that the level of education of the elderly is not directly associated with the increment in caries.     

Relationship between general health status and the change in chewing ability: a longitudinal study of the frail elderly in Japan over a 3-year period

Objectives: The aim of the present study was to identify the onset predictors of a change in chewing ability over a 3‐year period in the frail elderly. Methods: The subjects were frail elderly people living in southern Japan. Data were collected at baseline (n = 92) and 3 years later (n = 60). The dependent variable was a change in self‐rated chewing ability. The independent variables were age, gender, number of present teeth, dentition, maximum bite force (evaluated using a pressure‐sensitive foil), basic activities of daily living, self‐rated general health status, higher level of competence (evaluated using Tokyo Metropolitan Institute of Gerontology index), cognitive status (evaluated by revised Hasegawa Dementia Rating scale), and quality of life (evaluated using Philadelphia Geriatric Center morale scale) at baseline. To identify the most reliable predictors, bivariate analysis and multiple logistic regression analysis were performed, with the change of chewing ability as the dependent variable. Results: Bivariate analysis showed the change in chewing ability was significantly associated with general health status (p < 0.01), number of present teeth (p < 0.05) and maximum bite force (p < 0.01). Backward logistic regression analysis revealed that the most reliable predictor of a change in chewing ability at 3 years was general health status (odds ratio = 6.35, 95% CI = 1.69–23.88). Conclusion: The present findings suggest that general health status at baseline produces a change in chewing ability.     

Oral health and reduction in respiratory capacity in a cohort of community-dwelling elderly people: a population-based 5-year follow-up study

Objectives: Several anaerobic bacteria originating in periodontal pockets have been isolated from infected lungs and pharyngeal microflora. Increased bacterial load in lungs is known to be a risk factor for decline in forced expiratory volume during the first second. The aim was to evaluate both cross‐sectionally and longitudinally the association between oral health status and forced expiratory volume during the first second (FEV₁) in older residents of the city of Jyväskylä, Finland. Design: Cross‐sectional and prospective cohort study over a 5‐year follow‐up. Setting: Research laboratory of the University of Jyväskylä. Participants: In 1990 dental status and FEV₁ were examined in 203 80‐year‐old people, of whom 88 survivors were retested 5 years later. Main outcome measures: Primary: dental status and FEV₁. Secondary: existence of pulmonary diseases, height, handgrip strength, smoking, and length of education. Results: Participants were regrouped into three categories according to their baseline oral health status. At baseline, men with complete prostheses had the lowest FEV₁. Five years later the greatest reduction in FEV₁ was seen in subjects with poor periodontal status or complete prostheses (?9.4%) while those with healthy periodontal status showed no reduction in FEV₁ values (+1.0%, p = 0.006). Conclusions: Periodontal infections and complete prostheses may be reservoirs for pathogens which may be harmful and partly explain the observed reduction in FEV₁ during ageing.     

Nutritional status and oral status of the elderly with dementia: a 2-year study

doi: 10.1111/j.1741‐2358.2011.00555.x Nutritional status and oral status of the elderly with dementia: a 2‐year study Objectives: To determine the relationship between denture wearing and nutritional status in the elderly with dementia. Background: There could be a correlation between nutrition, oral health, dietary habits, patients’ satisfaction, and their socio‐economic status in the elderly, and the relationship between compromised oral status and nutritional status in the elderly with dementia. Subjects and methods: A 2‐year follow‐up study of 63 elderly Japanese women with and without dentures from a nursing home was undertaken to investigate their oral, physical and mental, and nutritional status. Results: Each item for 2006 and 2008 in this study showed no significant difference between 2006 and 2008, except the calories/day. The elderly with dementia without complete dentures during the 2 years of the study only significantly decreased the mean of the calories/day. Conclusion: The calories/day of the elderly with dementia without dentures decreased after 2 years. Denture wearing for the elderly with dementia could be necessary to maintain a satisfactory intake of calories.     

Oral health status of the elderly in a residential home in Turkey

Objectives: To determine the oral health status and treatment needs of elderly residents of a residential home in Ankara, Turkey. Background: Little is known about oral health problems of elderly living in the institutions. Methods: Among 216 elderly, 193 of them were interviewed and were clinically examined according to WHO criteria. Age, gender, educational and occupational status, oral hygiene practices, dental insurance, access to dental care and systemic diseases were recorded using a structured questionnaire. Coronal and root caries, periodontal disease, dental status and related treatment needs were assessed by two calibrated dentists. Results: The mean age of the subjects were 75.2 ± 8.3 in males, 79.1 ± 7.9 in females; 32.6% of subjects were dentate and the mean number of teeth was 3.7 ± 7.0 (median = 0). A functional dentition was present in 7.3% of subjects (≥20). The mean decayed, missing and filled teeth (DMFT) was 29.3 ± 5.8 (median = 32) and mean root caries was 2.2 ± 3.1 (median = 1.0). The major reason for tooth extraction was dental caries. Of the subjects, 20.7% had at least one untreated coronal caries and 18.1% root caries. The assessment of periodontal status according to CPI revealed that only four persons had nine healthy sextants with the score of ‘0’. Edentulousness was 67.4% while 11.9% of them lacked denture in both jaws. Conclusion: The results illustrated poor dental health and showed extremely high demand for the dental health services programmes for the elderly living in these institutions.     

Oral health of institutionalised elderly: a qualitative study of health caregivers’ perceptions in Brazil

doi: 10.1111/j.1741‐2358.2010.00366.x
Oral health of institutionalised elderly: a qualitative study of health caregivers’ perceptions in Brazil Objective: The aim of this study was to qualitatively explore caregivers’ perceptions of oral health care and factors influencing their work in a public long‐term care institution for the elderly in Goiania, Brazil. Method: Data were collected from a sample of 10 caregivers using personal in‐depth interviews and observation. Results: Caregivers were mainly nurses’ aides without training in oral health care. Oral health was associated with access to dental treatment, oral hygiene and use of dentures. Edentulousness, use of inappropriate dentures and appetite loss were perceived as negative images. Procedures used for oral hygiene were toothbrushing, mouth cleaning with a gauze and using a mouthwash. Conflicting priorities in routine care, lack of caregivers’ knowledge and the co‐operation of the elderly were the main obstacles to satisfactory oral care. Conclusion: Oral health care of the elderly was perceived as a burden by caregivers, and did not follow a standard protocol. Caregivers’ knowledge and perceptions reinforce the need for education and training in oral health issues.     

Effect of circadian rhythm type on serum lipid levels in shift workers: A 5-year cohort study

We investigated how differences in circadian rhythm type affect the health of workers engaged in shift work. Employees, who were newly hired in a steel company between 2007 and 2011, received the Morningness–Eveningness Questionnaire (MEQ) survey. The target participants were 153 male shift workers who were not being treated with any antihyperlipidemic drugs and underwent periodic physical examinations including blood tests at least twice. According to the score of the MEQ at the time of joining the company, we classified the subjects into five types. Longitudinal changes in serum lipid level were estimated among the circadian rhythm types adjusted for age, BMI, and other covariates using a linear mixed model. The regression coefficient of total cholesterol level in the “definitely and moderately morning” group was ?17.83 (95% confidence interval (CI): ?33.42 to ?2.23), and in the “intermediate ‘group’ was ?16.84 [95% CI: ?30.40 to ?3.28], compared to the moderate evening type.” The total cholesterol level was higher in the moderately evening type than in any of the other groups. Between the Morningness–Eveningness (ME) type and Low-density lipoprotein (LDL) cholesterol levels, compared with the “moderately evening type” group, the regression coefficient in the “intermediate type” group was ?16.08 (95% CI: ?28.79 to ?3.37), and in the “definitely and moderately morning type” group was ?17.50 [95% CI: ?32.11 to ?2.88]. The “moderately evening type” group had a higher LDL cholesterol level than any of the other groups. Evening-type circadian rhythm type shift workers are more prone to elevated serum lipid levels.     

Relationship of cariogenic bacteria levels with periodontal status and root surface caries in elderly Japanese

Objective: The relationship of the levels of cariogenic bacterial species with periodontal status and decayed root surfaces was investigated in elderly Japanese subjects. Methods: Three hundred and sixty‐eight individuals (each 75 years old) were examined for periodontal status (pocket depth, attachment loss), root surface caries and salivary levels of mutans streptococci (MS) and lactobacilli (LB). Results: Values >4 mm of attachment loss (rAL4) and for average attachment loss (aAL) of sites measured were significantly higher in subjects with LB than those without. Multiple regression analysis also showed a correlation between aAL and rAL4 values with the presence of LB (aAL p = 0.003; rAL4 p = 0.002). Further, multiple regression analysis of interacting factors regarding decayed root surfaces showed that LB carriers had a greater incidence of decayed root surface caries (p = 0.003), while MS and LB levels were correlated to the number of decayed root surfaces (LB p = 0.010; MS p = 0.026). Conclusion: Our results indicate that considerable attachment loss elevates the possibility of having LB, thus increasing the risk of root surface caries. It was also found that LB and MS measurements may be useful indicators of decayed root surfaces in elderly individuals with attachment loss.     

Does Helicobacter pylori eradication affect symptoms in nonulcer dyspepsia: a 5-year follow-up study

The role of Helicobacter pylori infection in nonulcer dyspepsia remains controversial. To date studies exploring the effect of H. pylori eradication on symptoms have reported conflicting results. Randomised control trials employing validated outcome measures have also been difficult to interpret because of several important issues such as the large placebo response seen in patients with nonulcer dyspepsia and both the natural variability in symptoms and symptom severity with time. The association of symptom improvement with resolution of gastritis has meant that the length of follow up employed in most studies has been insufficient. We report the findings of a randomised placebo controlled trial (n = 100), using a validated symptom questionnaire and 5 year follow up to determine the effect of H. pylori eradication on symptoms in nonulcer dyspepsia. In all 64 that were reviewed at 5 years there was a significant difference between patients who were H. pylori negative and those who remained positive with regard to complete symptom resolution, consumption of relevant medications and peptic ulcer disease development, in favour of active treatment. There was a trend for gradual symptom improvement over time irrespective of H. pylori status, which may reflect the natural history of this condition. For those who remained symptomatic at 5 years, there was no difference in symptom severity based on H. pylori status. The findings of this study support the use of H. pylori eradication in symptomatic patients with nonulcer dyspepsia both to induce symptom resolution and to prevent disease progression.     

The orodental status of a group of elderly in-patients: a preliminary assessment

Objective: To provide a preliminary assessment of the orodental status and dental treatment requirements of a group of elderly in-patients. Design: Cross-sectional. Setting: Acute Care of the Elderly and Stroke Rehabilitation units at teaching hospitals in Merseyside. Subject: 150 patients aged 58 to 94 years, in which a history could be validated at interview. Intervention: Questionnaire administered by dentist and clinical examination. Main outcome measures: Registration with a dentist, prosthetic status and difficulties with dentures, denture hygiene and identification marking, dental treatment needs and evidence of mucosal pathology. Results: Only 27% of patients claimed registration with a dentist. Three quarters of the patients were edentulous and 66 patients wore full dentures; 18 had no prostheses. Difficulties were experienced by one quarter of patients with upper dentures, compared with a half of lower denture wearers. Of the dentures available for inspection, 61 % had removable soft debris, 66% were left out at night and 75% were cleaned by the patient, whilst on the ward. No dentures had evidence of identification marking. Of the 39 partially dentate patients, 75% required interventive dental treatment. Denture stomatitis was diagnosed in 29% of patients and 19 had evidence of benign mucosal pathology. Conclusions: The orodental status of this group of elderly in-patients was poor, with a high proportion being edentulous. Few were registered with a dentist and denture hygiene was inadequate. Lack of identification marking is a matter of concern. Closer liaison between hospital staff responsible for elderly in-patients is required, to improve the orodental health and quality of life of this medically compromised group of patients.     

Factors related to the non-attendance in a clinical oral health study on the home-dwelling old elderly

Objective: To evaluate how elderly home-dwelling subjects’background factors, state of health, functional capacity and edentulousness related to their attendance in a comprehensive clinical dental study. Design: Cross-sectional population study; interview and clinical dental data. Setting: The City of Helsinki; clinical dental examinations at the Institute of Dentistry, University of Helsinki. Subjects: 600 elderly aged 76, 81 and 86 years, participants in the medical examinations in the Helsinki Ageing Study one year earlier, 81% being home-dwelling. Measures : Age, gender, marital status, family structure, educational level, former line of work, self-perceived general health, dentulousness, ability to move, sense of hearing, state of memory, clinical findings of dementia, other medical diagnoses, and intake of drugs. Outcome measure: Participation in clinical dental examinations. Results: The overall participation was 63% being reduced by high age and female gender, 75% of the 76-year-olds, but only 53% of those aged 81 or 86 years were clinically examined, figures were for men 72% and for women 60%. As shown by a multifactorial logit model, the strongest factors related to non-participation were the home-dwelling subjects’old age (OR=3.6), deteriorated ability to move (OR=5.3), clinically diagnosed symptoms of dementia (OR=4.1), or edentulousness (OR=2.5). Conclusion: Non-participation selectively by those edentulous will lead to prevalence figures on numbers of teeth being too optimistic for the entire elderly population.     

Variability of NT-proBNP and its relationship with inflammatory status in patients with stable essential hypertension: a 2-year follow-up study

Background

The variability of NT-proBNP levels has been studied in heart failure, yet no data exist on these changes over time in hypertensive patients. Furthermore, studies on the relationship between natriuretic peptides and inflammatory status are limited.

Methodology/Principal Findings

220 clinically and functionally asymptomatic stable patients (age 59±13, 120 male) out of 252 patients with essential hypertension were followed up, and NT-proBNP was measured at baseline, 12 and 24 months. No differences in NT-proBNP were found with respect to the basal stage in the hypertrophic group, but significant changes were found in non-hypertrophic subjects. The reproducibility of NT-proBNP measurements was better in patients with hypertrophy than in the non-hypertrophic group for the three intervals (stage I-basal; stage II-stage I; stage II-basal) with a reference change value of 34%, 35% and 41%, respectively, in the hypertrophic group. A more elevated coefficient of correlation was obtained in the hypertrophic group than in patients without hypertrophy: basal versus stage I (r = 0.79, p<0.0001 and r = 0.59, p<0.0001) and stage I versus stage II (r = 0.86, p<0.0001 and r = 0.56, p<0.0001). Finally, levels of NT-proBNP significantly correlated with sTNF-R1 (p<0.0001) and IL-6 (p<0.01) during follow-up. A multivariate linear regression analysis showed that sTNF-R1 is an independent factor of NT-proBNP.

Conclusions/Significance

This work shows that there is good stability in NT-proBNP levels in a follow-up study of asymptomatic patients with stable hypertension and left ventricular hypertrophy. As a consequence, assessment of NT-proBNP concentrations may be a useful tool for monitoring the follow-up of hypertensive patients with hypertrophy. Measured variations in peptide levels, exceeding 35% in a 12-month follow-up and 41% in a 24-month follow-up, may indicate an increase in cardiovascular risk, and therefore implies adjustment in the medical treatment. In addition, this study shows a link between neurohormonal and inflammatory activation in these patients.     

Effects of denture maintenance on satisfaction levels of Taiwanese elderly using removable partial dentures: a pilot study

doi: 10.1111/j.1741‐2358.2011.00500.x
Effects of denture maintenance on satisfaction levels of Taiwanese elderly using removable partial dentures: a pilot study Objective: The aim of this study was to evaluate the correlation between patient satisfaction with removable partial dentures and denture maintenance by patients, including regular application of denture adhesives and cleansers. Background: The success of removable partial dentures depends on patient satisfaction with dentures and their regular denture maintenance. Materials and methods: Demographic information, the Oral Impacts on Daily Performance (OIDP) indicator and details of denture maintenance (including the use of denture cleansers and adhesives) were collected from 193 (41.5% men and 58.5% women) participants by using questionnaires. A dentist performed oral examinations to evaluate denture function according to the OIDP items photographically and recorded the number of remaining teeth and Kennedy’s classification. Results: Most participants were satisfied with their removable partial dentures and tended to have higher satisfaction levels than the dentist’s estimation. Further, those using denture adhesives and cleansers had higher satisfaction levels than those not using such denture maintenance. Conclusions: Appropriate education regarding denture use is important because regular denture maintenance by patients affects their degree of satisfaction with dentures, as well as the dentist’s skill and the patient’s oral condition. Dentists could use this information to predict the potential success of dentures.     

Naps and exercise: reinforcing a range of benefits for elderly health

According to the United Nations, in 2017, people aged 60 or over in the world, comprised 13 per cent of the global population. It is a fact that elderly people are keeping a health lifestyle, such as practicing physical exercises and avoiding excessive dosages of medications. However, this population is also more prone to have injuries while practicing exercises. Sleep architecture is physiologically different among elderly, and naps can be very beneficial to improve their mental and physical health. Thus, in this article, we encourage health professionals to recommend regular naps to this population, which could lead to an improve in their well-being and quality of life.     

Overtime work as a predictor of major depressive episode: a 5-year follow-up of the Whitehall II study

Background

The association between overtime work and depression is still unclear. This study examined the association between overtime work and the onset of a major depressive episode (MDE).

Methodology/Principal Findings

Prospective cohort study with a baseline examination of working hours, psychological morbidity (an indicator of baseline depression) and depression risk factors in 1991–1993 and a follow-up of major depressive episode in 1997–1999 (mean follow-up 5.8 years) among British civil servants (the Whitehall II study; 1626 men, 497 women, mean age 47 years at baseline). Onset of 12-month MDE was assessed by the Composite International Diagnostic Interview (CIDI) at follow-up. In prospective analysis of participants with no psychological morbidity at baseline, the odds ratio for a subsequent major depressive episode was 2.43 (95% confidence interval 1.11 to 5.30) times higher for those working 11+ hours a day compared to employees working 7–8 hours a day, when adjusted for socio-demographic factors at baseline. Further adjustment for chronic physical disease, smoking, alcohol use, job strain and work-related social support had little effect on this association (odds ratio 2.52; 95% confidence interval 1.12 to 5.65).

Conclusions/Significance

Data from middle-aged civil servants suggest that working long hours of overtime may predispose to major depressive episodes.     

Recall of an oral health education programme by nursing personnel in special housing facilities for the elderly

Objectives: To investigate the recall of oral health knowledge and confidence by nursing personnel in special housing facilities for the elderly, three years after an education programme. Design: A cross sectional design using a questionnaire. Sample: All nursing personnel, a total of 2,901 subjects, in five municipalities in south‐western Sweden; of whom 950 had attended the programme. The response rate was 67% (1930 subjects). Intervention: An oral health education programme consisting of four one‐hour lessons. Results: The oral health education programme still had an effect on the participants' attitudes towards oral health three years later. When comparing the trained group (OHEP+) which attended the programme with those who did not have training (OHEP‐), the perceived ability, opportunity and the knowledge of oral health were significantly better in the former group, p<0.01 Eurther, within the OHEP‐ group who did not attend the programme there was a significant difference in the perceived ability, opportunity and the knowledge of oral health between those with a higher level of health care education, p<0.01. Conclusions: The effect of an oral health education programme on the participants' attitudes towards oral health persists at least for three years. The data indicate that trainees with a low level of health care education benefit most.     

A cross-sectional study of oral health and oral health-related quality of life among frail elderly persons on admission to a special oral health care programme in Copenhagen City, Denmark

doi: 10.1111/j.1741‐2358.2011.00486.x
A cross‐sectional study of oral health and oral health‐related quality of life among frail elderly persons on admission to a special oral health care programme in Copenhagen City, Denmark Aim: To describe the oral health and the oral‐health‐related quality of life (OHRQoL) of citizens in Copenhagen City on admission to a specific oral health‐care programme for disabled elderly persons. Further, to analyse how various factors influence the oral health and the OHRQoL among these patients. Methods: A cross‐sectional study of 189 persons (average 85 years) consecutively admitted to a special oral health‐care programme. Clinical data and data from interviews comprising social factors, life‐style, dental visit habits, oral hygiene practices and self‐perceived oral health were collected. A modified index on perceived dysfunction, discomfort and disability due to oral disorders was used. Results: Sixty‐eight per cent had natural teeth, among those 57% had decayed teeth and two out of three wore dentures. Smoking habits influence the number of teeth present and the OHRQoL (p < 0.05) of the patients. Edentulousness, decayed teeth, and presence of dentures did not seem to cause OHRQoL problems, while higher OHRQoL scores (more problems) were reported by those with 1–9 teeth and tooth mobility. Conclusion: OHRQoL of these patients can be increased by removal of loose teeth and provision of dentures to those with very few teeth rather than focus on traditional caries treatment.
