Objective: This study used a precise weighing method to assess whether tooth loss was related to nutrient intake in elderly Japanese subjects. Material and methods: Fifty‐seven subjects aged 74 years were randomly selected from a longitudinal interdisciplinary study of ageing. Complete 3‐day food intake data were obtained by a precise weighing method. The dietary intakes of energy and nutrients were calculated based on the Standard Tables of Food Composition in Japan (5th ed.). A clinical evaluation of the number of teeth present was carried out. Multiple regression standardised coefficients for each nutrient was estimated based on a continuous scale adjusted for gender, smoking habits, and educational level. After dividing the subjects into two groups according to the number of teeth present (0–19, 20+), the difference in the intake of nutrients and the amount of food consumed per day was evaluated. Results: The number of teeth present had a significant relationship with the intake of several nutrients. In particular, total protein, animal protein, sodium, vitamin D, vitamin B1, vitamin B6, niacin, and pantothenic acid were significantly associated with the number of teeth present and with the two groups (0–19, 20+). The intake of vegetables and fish, shellfish, and their products was significantly lower among subjects with fewer teeth. Conclusion: This study suggests that there was a significant relationship between nutrient intake, such as minerals and vitamins from food, and tooth loss. 相似文献

Objective: We hypothesise that a difference in nutrition influences dental caries and periodontal disease. There are few previous studies especially longitudinal ones which have evaluated this hypothesis. This study investigated the relationship between nutritional intake, including milk and milk products (MMP), and dental disease, controlling for several confounding factors. Material and methods: A group of 600 subjects aged 70, randomly selected for this study, included approximately the same number of male and female subjects. The number of teeth on which root caries had occurred or where there was a periodontal event over a 6‐year period was measured. To determine quantitative food intake at baseline, a semi‐quantitative food frequency questionnaire was used during face‐to‐face interviews by dieticians. The stepwise method of multiple linear regression analysis was used to identify independent predictors of the number of root caries or periodontal disease events during the 6 years. Intake of the six food groups includes (i) fish, shellfish, meat, beans and eggs; (ii) MMP; (iii) dark green and yellow vegetables (DYV); (iv) other vegetables and fruits; (v) cereals, nuts and seeds, sugar and sweeteners, confectioneries (CNSC) and (vi) fats and oils. The alcohol, gender and anthropometric evaluation including measurements of weight and height for the calculation of body mass index, educational level, the number of family members and the number of remaining teeth were used as independent variables. Results: According to stepwise multiple regression analysis, two variables (quantity of MMP, and gender) were negatively associated with the number of root caries events during the 6 years. The standardised coefficients were ?0.14 (p = 0.035) and ?0.17 (p = 0.007) respectively. In addition, DYV were negatively, and three other variables (CNSC; alcohol; and the number of remaining teeth at baseline) were positively associated with the number of periodontal disease events during the 6 years. The standardised coefficients were ?0.16 (p = 0.001), 0.11 (p = 0.042), 0.10 (p = 0.041) and 0.58 (p < 0.001) respectively. Conclusion: Our results suggest that the intake of MMP in this elderly population correlated with root caries events. In addition, intake of vegetables negatively correlated, and intake of ‘CNSC’ positively correlated with periodontal disease events. 相似文献

doi: 10.1111/j.1741‐2358.2012.00656.x Assessing changes in oral health‐related quality of life and its factors in community‐dwelling older Brazilians Objective: To describe changes in oral health‐related quality of life and to evaluate the associations of these changes in community‐dwelling older people. Materials and methods: In this longitudinal study a representative sample of 872 older people, living in Brazil, was evaluated during 2004. The follow‐up was carried out during 2008, with 587 older persons evaluated. A questionnaire assessing socio‐demographic information, health history, oral health‐impact profile and number of natural teeth was used. Changes in oral health‐related quality of life were categorized as improvement or deterioration. Data analysis was performed using a hierarchical approach based in a conceptual framework. A hierarchal approach was carried out using Poisson regressions. Results: Older persons living in rural areas, those who reported brushing once a day or less and older persons with fewer natural teeth had an increased chance of reporting deterioration in oral health‐related quality of life. Women and participants who received a minimum wage of less than US$219.50 were more likely to report improvement in oral health‐related quality of life. Conclusion: The results of this study suggest that changes in the oral health‐related quality of life are influenced by many of the variables that were included in the conceptual framework. 相似文献

doi:10.1111/j.1741‐2358.2009.00299.x A comparison of patient satisfaction between treatment with conventional complete dentures and overdentures in the elderly: a literature review Background: It has been stated that mandibular overdentures are more satisfactory than conventional dentures, but problems relating to the use of retrospective ratings, lack of control group and sequential provision of treatment may compromise the findings. Objective: To establish a comparison between treatment with conventional complete dentures and implant‐retained overdentures in elderly patients by conducting a literature review. Materials and methods: A search of English language peer‐review literature was completed using Medline up to 2008 focusing on evidence‐based research. Randomised clinical trials (RCTs) and longitudinal prospective studies were favoured in the review, using a general hierarchical classification. Articles that did not focus exclusively on the comparison of patient satisfaction between complete dentures and overdentures were excluded from further evaluation. The last search was conducted in February 2008. Key terms included quality of life, patient satisfaction, edentulism, complete denture and overdenture. Results: Among the 90 articles found in the initial search, 27 met the inclusion criteria. This included 18 RCTs and eight prospective and one cohort study. Most of the articles stated superiority of the mandibular implant‐retained overdenture therapy over the conventional complete denture regarding patient satisfaction and quality of life. Conclusion: Even with implant treatment presenting higher patient satisfaction and improvement of quality of life, it was not possible to establish a direct comparison between the studies due to differences in adopted methodologies. 相似文献

Objectives: The aim of this study was to compare the satisfaction and the quality of life in an elderly population using either mandibular conventional dentures or implant‐retained overdentures. Materials and methods: A total of 34 patients were divided into two groups: group I – complete dentures users; group II – users of upper complete dentures opposed by implant‐retained overdentures. The subjects were submitted to a questionnaire based on Oral Health Impact Profile and oral health related quality of life to evaluate their satisfaction levels and quality of life with their prostheses. Data were evaluated using a non‐parametric statistical analysis (Fischer test) with significant difference at α = 0.05. Results: There were no significant differences between the groups in relation to comfort, aesthetics, chewing ability, overall satisfaction, pain, functional, phonetic, social, and psychological limitations (p > 0.05). Comparing the stability of mandibular dentures, group II presented the better results (p < 0.05). Conclusion: Although the stability of the mandibular implant‐retained overdenture was enhanced compared to a conventional denture, the quality of life and satisfaction levels were similar for both the groups. 相似文献

doi:10.1111/j.1741‐2358.2009.00343.x Implant‐supported overdenture in an elderly patient with Huntington’s disease Huntington’s disease is a hereditary, progressive, neuro‐degenerative disorder characterised by increasingly severe motor impairment, cognitive decline and behavioural manifestations leading to functional disability. Dyskinesia and hyperkinesia of the tongue and the peri‐oral musculature make it impossible for the patient to wear a conventional complete denture, despite an adequate alveolar ridge. The present paper reports on a patient with Huntington’s disease who was rehabilitated with a mandibular overdenture supported by two endosteal implants. One year follow‐up examination showed that the prosthesis was stable and there was considerable improvement in the patient’s masticatory function. 相似文献

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. 相似文献

In the framework of the effective field theory for the order parameter, which characterizes the degree of deviating the protein globule structure from its native state, the phase transition of the protein macromolecule from the elastic state into the plastic one under its mechanical stretching is considered. Elastic properties of a protein are studied as a function of the applied force, temperature, and the mean coordination number of the protein “network.” Proteins 2014; 82:966–974. © 2013 Wiley Periodicals, Inc. 相似文献

doi: 10.1111/j.1741‐2358.2012.00651.x Oral health‐related quality of life and nutritional status of institutionalized elderly population aged 60 years and above in Mysore City, India Objective: To assess whether oral health–related quality of life (OHRQoL) is associated with nutritional status in the institutionalised elderly population of Mysore. Background: Malnutrition in the elderly has an evident impact on their general health and quality of life. Analysis of data of the Geriatric Oral Health Assessment Index (GOHAI) and their association with the Mini Nutritional Assessment (MNA) results improves our understanding of the complex relationship between oral health and malnutrition. Materials and methods: The study was conducted among the institutionalised elderly population in Mysore city, Karnataka. Data on socio‐demographic, oral health status were gathered. OHRQoL was evaluated using GOHAI, and malnutrition risk using MNA. Results: Out of 141 elderly, 41.1% were men and 58.9% were women with mean age of 72.2 ± 7.5 years. Mean GOHAI score was 47.03 ± 9.2, with 69.5% had low perception of oral health. Mean MNA score was 9.91 ± 2.4, 15.6% were malnourished, 52.5% were at risk of malnutrition and 31.9% were adequately nourished. A strong association was found between the mean GOHAI and MNA scores. Conclusion: Oral health–related quality of life was associated with nutritional deficit, and it requires a greater integration between dentistry and nutrition in the health promotion of older adults. 相似文献

Daily intake of gross energy (DGEI) and protein (DGPI) of Japanese monkeys in a cool temperature forest were investigated in different four seasons. As a result, dramatic seasonal differences in DGEI and DGPI were found: DGEI and DGPI in winter were significantly lower than those in spring and autumn, being only about 17–42% of those in the two seasons. DGEI and DGPI in summer were also lower than those in autumn and spring, being only about 29–52% of those in the two latter seasons. Seasonal comparisons of some variables on food qualities revealed that much lower values of DGEI and DGPI in winter and summer were influenced srongly not so much by the lower calorie and protein content of food as by the lower speed of dry weight intake. Multiple regression analyses for each food item revealed that the unit weight was a more important factor in determining the speed of dry weight intake than was the speed of unit intake. In addition, the speed of dry weight intake contributed much more to the speed of calorie and protein intake than did the content of calorie and protein. Multiple regression analyses, employing DGEI and DGPI (as dependent variables) and daily mean values of some variables related to food quality (as independent variables), revealed that the mean values of speed of calorie and protein intake on food items eaten in a day could explain 79.0% and 85.9% of the variance in DGEI and DGPI, respectively. In addition, the mean value of the speed of dry weight intake of food items eaten in a day can be used to explain 74.3% and 52.8% of the variance in DGEI and DGPI, respectively. These findings suggested that not only nutritional content of food but also the speed of dry weight intake strongly determined the nutritional condition of nonhuman primates. Am. J.

doi:10.1111/j.1741‐2358.2009.00344.x Oral health‐related quality of life in patients receiving home‐care nursing: associations with aspects of dental status and xerostomia Objective: To explore the differences in oral status, dental attendance and dry mouth problems between patients with long‐term disease with high and low scores on Oral Health Impact Profile 14 (OHIP 14) and how patients cope with oral problems such as xerostomia and a reduced ability to brush their teeth. Background: There has been a lack of studies of oral health and oral health‐related quality of life in the frail elderly within the community services. Materials and methods: A cross‐sectional questionnaire study was conducted with 137 patients receiving home‐care nursing. Structured interviews were conducted by student nurses using OHIP‐14, items from the Xerostomia Inventory and questions concerning dental visit habits, brushing of teeth and data from medical records. Results: Eighty‐three per cent of patients had natural teeth and 60% had only natural teeth. ‘Natural teeth only’ indicated a low score on OHIP‐14. Problems with brushing and items concerning xerostomia indicated a high score on OHIP‐14. Contrasts in the assessments concerning brushing of teeth and xerostomia indicated low priority from the patients themselves and the nursing staff. Conclusion: Community health services should focus upon oral health. Both patients and nurses should assess the need for regular brushing of teeth carried out by home‐care nurses. Assessment and treatment of dry mouth problems should have higher priority. 相似文献

doi: 10.1111/j.1741‐2358.2011.00592.x A 3‐year longitudinal study of quality‐of‐life outcomes of elderly patients with implant‐ and tooth‐supported fixed partial dentures in posterior dental regions Background: Clinical studies have mainly been focused on oral health‐related quality‐of‐life (OHRQoL) outcomes of removable dentures. Objective: To evaluate therapy of elderly patients with implant‐supported fixed partial dentures (IFPD) and tooth‐supported fixed partial dentures (FPD) in the posterior dental regions. Patients and methods: The OHIP49 was used to measure OHRQoL in 64 patients with IFPD and 38 patients with FPD, before, 3 weeks and 3 years after rehabilitation. A control group (CG) consisted of 62 individuals. Results: The Oral Health Impact Profile questionnaire (OHIP) follow‐up scores of the patients with FPD and the patients with IFPD were significantly smaller in comparison with the baseline scores (p < 0.01). The OHIP scores were further reduced at the 3‐year follow‐up. The patients with IFPD had significantly higher scores than the patients with FPD and the CG at the baseline and at the follow‐ups. In the patients with FPD, both age groups (≤60 and >60) showed equal improvement of the OHRQoL. In the IFPD group, patients older than 60 years showed better improvement (p < 0.05). There were no significant differences dependent on gender and antagonistic teeth (p > 0.05). Conclusion: The FPD and the IFPD treatment showed significant improvement of OHRQoL. The FPD treatment improved OHRQoL equally in both age groups, while the IFPD treatment improved OHRQoL better in older patients. 相似文献
