Abstract
BACKGROUND Due to the increasing proportion of older adults in Korea and growing interest in aging, the concepts of oral aging and oral hypofunction have recently been introduced. Thus, it is necessary to investigate the age-specific oral function levels of Korean older adults and develop expert intervention methods for healthy aging. METHODS Dysphagia, independence of daily living, and oral hypofunction were assessed in 206 older adults living in Wonju, Gangwon State, South Korea. Subjective dysphagia was assessed through self-report questionnaires using the Dysphagia Handicap Index (DHI), the Korean version of Eating Assessment Tool-10, and the Korean version of the Modified Barthel Index. In addition, the oral hypofunction assessment items included decreased chewing ability, occlusal pressure, tongue pressure, oral dryness, and oral cleanliness. RESULTS DHI increased significantly with age, with those in their 80 s reporting the most difficulty swallowing. Oral function in terms of chewing ability (maximum occlusal pressure and number of remaining teeth), maximum occlusal pressure, and maximum tongue pressure also declined with increasing age. While there was no significant difference in oral dryness by age, those in their 80 s had dry mouth according to the criteria of the oral moisture checking device. CONCLUSIONS In an assessment of oral function in community-dwelling, independent Korean older adults, the number of items that were assessed as oral hypofunction increased with age. The findings can be used to standardize the oral hypofunction assessment item and develop age-based individualized intervention plans for the early management of oral health and individual oral myofunctional rehabilitation in Korean community-dwelling older adults.

Abstract
BACKGROUND Oral well-being is an important component of general well-being and quality of life, as it is greatly influenced by the ability to chew and speak, and thus by central factors of social interaction. Because quality of life and participation are important factors for health in older age, the aim of this article was to examine the chewing ability, including associated factors, for the older population in Germany on the basis of a nationally representative sample. METHODS Database is the German Health Update (GEDA 2019/2020-EHIS), a population based cross-sectional survey of the Robert Koch Institute. In the telephone interview, participants aged 55 years and older were asked: "Do you have difficulty biting and chewing on hard foods such as a firm apple? Would you say 'no difficulty', 'some difficulty', 'a lot of difficulty' or 'cannot do at all/ unable to do'?" Prevalences and multivariate prevalence ratios (PR) were calculated with 95% confidence intervals (95% CI) from log-Poisson regressions. Sociodemographic, health-, behavioral- and care-related characteristics were investigated as associated factors. RESULTS The analyses were based on data from 12,944 participants (7,079 women, 5,865 men). The proportion of people with reduced chewing ability was 20.0%; 14.5% had minor difficulty, 5.5% had major difficulty. There were no differences between women and men. The most important associated factors for reduced chewing ability were old age (PR 1.8, 95% CI 1.5-2.1), low socioeconomic status (PR 2.0, 95% CI 1.7-2.5), limitations to usual activities due to health problems (PR 1.9, 1.6-2.2), depressive symptoms (PR 1.7, 1.5-2.1), daily smoking (PR 1.6, 95% CI 1.3-1.8), low dental utilization (PR 1.6, 95% CI 1.4-1.9), and perceived unmet needs for dental care (PR 1.7, 95% CI 1.5-2.1). CONCLUSIONS One fifth of adults from 55 years of age reported reduced chewing ability. Thus, this is a very common functional limitation in older age. Reduced chewing ability was associated with almost all investigated characteristics. Therefore, its prevention requires a holistic view in the living environment and health care context of older people. Given that chewing ability influences quality of life and social participation, maintaining or improving chewing ability is important for healthy aging.

Abstract
OBJECTIVE This scoping review describes the relationship between tooth retention, health, and quality of life in older adults. METHODS Seven databases were searched for English language articles for subjects ≥ 65 y from 1981 to 2021. Exposure was tooth retention (≥ 20), and outcomes were general/systemic health and quality of life. Methodological quality was assessed using the Newcastle-Ottawa Scale and Cochrane Risk of Bias 2.0 tool. RESULTS 140 articles were included, only four were randomized trials. Inter-rater agreement (κ) regarding study inclusion was 0.924. Most were assessed with low risk of bias (n = 103) and of good quality (n = 96). Most studies were conducted in Japan (n = 60) and Europe (n = 51) and only nine in the US. Tooth retention was referred to as "functional dentition" in 132 studies and "shortened dental arch" in 19 studies. Study outcomes were broadly synthesized as (1) cognitive decline/functional dependence, (2) health status/chronic diseases, (3) nutrition, and (4) quality of life. DISCUSSION There is a positive relationship between tooth retention, overall health, and quality of life. Older adults retaining ≥ 20 teeth are less likely to experience poorer health. Having < 20 teeth increases the likelihood for functional dependence and onset of disability, and may affect successful ageing. This review supports the general finding that the more teeth older adults retain as they age, the less likely they are to have adverse health outcomes. However, significant knowledge gaps remain which can limit decision-making affecting successful ageing for many older adults. This review highlights the need to consider, as an important marker of oral health and function, the retention of a functional minimum of a natural dentition, rather than a simple numeric score of missing teeth.

Abstract
Background Masticatory ability is an essential factor for sustaining quality of life and social and systemic well-being, particularly in elderly. This study aimed to reveal the association between subjective masticatory difficulty and skeletal bone mineral density (BMD). Methods Data from the Korean National Health and Nutrition Examination Survey, which was conducted from 2008 to 2011 were analyzed. This study included 13,092 Koreans (5656 males, 7436 females) over 50 years of age. Masticatory difficulty was evaluated based on a self-reported questionnaire. Areal BMD of the total hip, femoral neck, and lumbar spine as well as lean body mass were determined using dual-energy X-ray absorptiometry. Data about the sociodemographic characteristics, physical activity, number of teeth present, sum of decayed, missing, and filled permanent teeth (DMFT) index and Community Periodontal Index (CPI) were collected. Multivariate logistic regression analysis was conducted to analyze associations between subjective masticatory difficulty and BMD, adjusting for the confounding covariates. Results Significant differences were observed in the areal BMD of the total hip, femoral neck, and lumbar spine as well as lean body mass accordance with the presence of subjective masticatory difficulty in both males and females. The number of teeth, DMFT, and CPI score did not show significant differences based on the presence of self-reported satisfaction of chewing performance in both males and females. Results from multivariate logistic regression demonstrated that the subjective masticatory difficulty showed significant interactions with skeletal BMD and the associations between masticatory satisfaction and BMD of the total hip and femoral neck were more prominent in females compared to those in males. Conclusions The skeletal BMD, particularly areal BMD of the femoral neck was significantly associated with subjective masticatory difficulty in elderly, especially in elder females.

Abstract
There are very few studies on metabolic syndrome (MetS) and oral health in postmenopausal women. The purpose of this cross-sectional study was to determine the association between MetS and its components and the number of remaining teeth in postmenopausal women in Korea. The study selected 3320 menopausal women (40-79 years old) from those who participated in the seventh Korea National Health and Nutrition Survey (2016-2018). Multiple regression and multiple logistic regression analyses were performed to determine the association between MetS and its components and the number of remaining teeth. According to the multiple regression analysis, the regression coefficient (B) values were -1.62 (p < 0.05), -1.31 (p < 0.05), -1.60 (p < 0.05), and -2.28 (p < 0.05) in the hypertension group, hyperglycemia group, low high-density lipoprotein (HDL) cholesterol group, and MetS prevalence group, respectively. This indicates that the number of remaining teeth was lower in the MetS prevalence group as compared to the non-prevalence groups. As observed in the multiple logistic regression analysis, the odds ratio of the number of remaining teeth (less than 20) was higher in the MetS prevalence group (1.82 (p < 0.05)) as compared to the non-prevalence groups (1.25 (p < 0.05) in the abdominal obesity group, 1.50 (p < 0.05) in the hypertension group, 1.36 (p <0.05) in the hyperglycemia group, and 1.72 (p < 0.05) in the low HDL cholesterol group). Therefore, our results indicate that abdominal obesity, hypertension, diabetes, dyslipidemia, and prevalence of MetS are associated with tooth loss in postmenopausal women.

Abstract
AIM We aimed to clarify the association between deterioration of periodontal status and masticatory performance in a longitudinal follow-up study of a general urban population. MATERIALS AND METHODS This study investigated 663 participants in the Suita study with no changes in the number of functional teeth or occlusal support areas during a 5-year follow-up period. Participants were classified into three groups according to changes in periodontal status during the survey period: a recovered group; a stable group; and a deteriorated group. Rate of masticatory performance change was calculated by subtracting the value at baseline from the value at follow-up and dividing the resulting value by the baseline value. RESULTS Median rates of masticatory performance change were -11.7% in the recovered group, -19.2% in the stable group, and -30.8% in the deteriorated group, and these values were significantly different (p < .001). Multiple regression analysis revealed periodontal status group (recovered group: reference; stable group: p = .029; deteriorated group: p = .006) as an independent variable was significantly associated with the rate of masticatory performance change. CONCLUSION The present results suggest that deterioration of periodontal status increases the risk of age-related declines in masticatory performance.

Abstract
Background The impact of poor oral health on older adults’ quality of life is a public health problem. In this study, the mediating effects of dental status, occlusal condition, dysphagia, and masticatory performance on the association between xerostomia and oral health-related quality of life (OHRQoL) were assessed in the older adult population. Methods Stratified cluster sampling was used to recruit 1076 community-dwelling adults aged 65 years and older from Kaohsiung, Taiwan. Community care centers were randomly selected according to their geographic classifications (urban, rural, or mountainous areas). Assessments of dental status and occlusal condition were performed by dentists. Information on demographics, physical function, xerostomia, dysphagia and depression was collected through face-to-face interviews. Masticatory performance was evaluated using color-changeable chewing gum. OHRQoL was measured using the Geriatric Oral Health Assessment Index. Hierarchical regression models were used to assess the relationships between OHRQoL and physical function, dental status and oral function in older adults. Path analysis was used to estimate direct and indirect pathways between xerostomia and OHRQoL. Results Participants with xerostomia exhibited a 0.20 OHRQoL reduction (p < .001) compared with patients with no xerostomia, and the direct effect accounted for 83.3% of the total effect. Dysphagia and masticatory performance were found to exert significant mediating effects on the association between xerostomia and OHRQoL (βs = 0.20 and − 0.12, respectively; both p < .001; βs = 0.06 and − 0.09, respectively; both p < .05). Moreover, potential mediating effects of the number of functional teeth (βs = − 0.11 and − 0.43, respectively; both p < .001) and occlusal condition (βs = 0.09 and 0.13, respectively; both p < .05) on the relationship between xerostomia and masticatory performance were noted. Conclusions Dysphagia and masticatory performance may serve as pathways through which xerostomia affects quality of life. Early oral function intervention may be a valuable and actionable target for older adults to maintain quality of life. Our results further suggest that checkup and screening for oral dysfunction are essential to prevent or delay the onset of complications.

Abstract
OBJECTIVES Declines in masticatory performance might be a risk factor for worsening nutritional intake and result in general frailty. The present study constructed and investigated a method to predict the extent to which objective masticatory performance declines with age in cases with poor oral health status. METHODS Participants comprised 1201 participants in the Suita study with dental checkup at both baseline and follow-up (500 men and 701 women; age at baseline, 65.6 ± 7.8 years; mean follow-up, 5.1 ± 1.1 years). First, multiple linear regression analysis was performed with masticatory performance at follow-up as the dependent variable and sex as well as baseline age, number of functional teeth, maximum bite force, occlusal support, periodontal status, salivary flow rate, and masticatory performance as independent variables. Scores were assigned to each factor based on the standardized partial regression coefficient obtained from multiple linear regression analysis. Participants were divided into quintile groups (Q1-Q5) based on total scores for factors, and rates of masticatory performance change for each group were calculated and compared. RESULTS Mean rates of masticatory performance change in groups Q1-Q5 from the model to predict declining masticatory performance were: Q1, -9.7%; Q2, -12.7%; Q3, -18.0%; Q4, -19.9%; and Q5, -29.8%.Thus there was a trend for masticatory performance to decrease with decreasing score. CONCLUSIONS The model developed in this study quantitatively predicted declines in masticatory performance after approximately 5 years. CLINICAL SIGNIFICANCE We developed a model for predicting the extent to which masticatory performance will change over the next 5 years. This model may offer a useful tool when taking measures to prevent declines in masticatory performance with aging.

Abstract
Aging impairs senses, mastication, oral status and function, causing nutritional needs and diet insufficiencies. The present needs of independent older adults suggest that health research and oral health care should shift from reductionist disease management to integral and personal treatment plans, including lifestyle, psychological, nutritional and oral health coaching approaches. Dentists and other medical professionals that work in the field of gerodontology should be educated on the macro and micronutrient needs of the elderly and incorporate certain nutritional plans early in the life of their patients with their approval and cooperation, in order to postpone tooth loss and masticatory impairment. Old recipes such as the Mediterranean diet should be kept as a base for all the elderly and be enriched in a customized interpersonal way from the dentist as well as the medical professional according to the specific needs of one's oral and general health status. In this nonsystematic review paper, the basic aspects of the vicious cycle of nutrition and oral health status are discussed and suggestions of major nutrients' influence and needs for independent elders are reported. Based on the scientific data collected, suggestions are made for the food industry for better quality and dosage of foods for this category of individuals. Such strategies can be a whole new area of interest for the food industry in order to obtain better quality of food packaging for the independent OA with accepted texture, odor, colors, macronutrients and micronutrients' consistency and in specific portions.

Abstract
OBJECTIVE Oral function disorders occur often in older people with increasing age. Oral function disorders affect bodily function and self-esteem, which are related to quality of life (QOL). The aim of this study was to evaluate the effectiveness of an oral function intervention programme on the oral function of older Taiwanese people. MATERIALS AND METHODS A one-group pretest-post-test study design was used. A total of 529 older Taiwanese people (women, 68.2%; men, 31.8%; average age, 75.07 ± 5.95 years) participated in this study. The oral function intervention programme consisted of a brief oral health education programme and oral function exercises. The total test period was 8 months. The oral condition and function examination comprised two questionnaires (self-reported symptoms of oral function disturbance and the Geriatric/General Oral Health Assessment Index [GOHAI]) and three oral function assessments (Repetitive Saliva Swallowing Test [RSST], Oral Diadochokinesia Test [ODT] and Cheek Expanding Test [CET]). RESULTS After the oral function intervention, the self-reported symptoms on the oral function questionnaire and GOHAI showed significant improvement (P < 0.05). Additionally, RSST, ODT and CET showed differences between pretest and post-test measurements (P < 0.05). CONCLUSION The oral function intervention programme was effective in maintaining their feeding, swallowing and articulatory functions of older Taiwanese people. Significant improvements in self-reported symptoms of oral function and GOHAI scores indicated that the oral function intervention programme might improve the QOL of older Taiwanese people.

Abstract
OBJECTIVES To explore the failure of the oral health-related section of the interRAI (ohr-interRAI), this study investigated test content validity (A.) and reasons for inaccurate assessments (B.). BACKGROUND Poor oral health negatively affects quality of life and is associated with a number of systemic diseases. The interRAI instruments, internationally used for geriatric assessment, should accurately detect oral conditions that require care. Previous research showed that the ohr-interRAI and related precursor versions do not achieve this goal. MATERIALS AND METHODS (A.) A group of 12 experts rated completeness, relevance, clarity of wording and feasibility of the ohr-interRAI. Content validity indices were calculated per item (threshold 0.78). (B.) Focus group discussions with 23 caregivers were organized. A semi-structured question guide made sure that all topics of interest were covered. Qualitative content structuring analysis was applied after transcription. RESULTS (A.) Experts agreed on the relevance of the items on chewing, pain, gingival inflammation and damaged teeth. They regarded none of the items as worded clearly and only prosthesis use and pain were considered to be assessable by untrained caregivers. All experts agreed that the ohr-interRAI was incomplete. (B.) Focus group discussions revealed that in the care environment oral health had low priority. Aspects related to the ohr-interRAI itself and aspects related to the assessment situation impeded the oral health assessment. The approach of the caregivers to complete the ohr-interRAI was inappropriate to accurately detect oral care needs. CONCLUSIONS Findings challenge test content validity of the ohr-interRAI and reveal reasons for inaccurate assessments.

Abstract
Introduction: Although previous studies have identified various factors related to masticatory performance, which factors affect longitudinal changes in masticatory performance have not been clarified. Objectives: We aimed to clarify factors involved in changes to masticatory performance and construct models from factors related to masticatory performance in a longitudinal study of a general urban population in Japan. Methods: A total of 1,005 Japanese subjects (411 men, 594 women; mean age at baseline, 65.7 ± 7.7 years; mean follow-up period, 5.0 ± 0.9 years) were included in the Suita study. These subjects participated in dental checkups both at baseline (June 2008–December 2011) and at follow-up (June 2013–January 2017). The number of functional teeth and occlusal support areas was recorded and the latter assessed using the Eichner index. Subjects’ periodontal status was evaluated based on the Community Periodontal Index. Masticatory performance was determined using test gummy jelly. Factors affecting masticatory performance at follow-up and the degree of their effect were investigated by multiple linear regression analysis. Results: In multiple linear regression analysis with masticatory performance at follow-up as the dependent variable, baseline age, masticatory performance, number of functional teeth, and maximum bite force were significant independent variables. The results of multiple linear regression analyses by occlusal support at baseline identified only maximum bite force at baseline in subjects who were Eichner A and baseline age, masticatory performance, and number of functional teeth in subjects who were Eichner B as significant independent variables concerning masticatory performance at follow-up. Conclusion: Our study showed a relationship between longitudinal changes in masticatory performance and age, number of functional teeth, and maximum bite force and furthermore showed that the effects of these factors vary according to the residual number of occlusal support areas. Knowledge Transfer Statement: Patients and clinicians should recognize the importance of objective and quantitative assessment for chewing efficiency and understand that various factors are related to longitudinal changes in masticatory performance. The results of this study can provide basic data for preventing or improving the decline in masticatory performance for elderly people with varying numbers of occlusal support areas.

Abstract
Objectives To identify relationships between masticatory ability and age, and dental and prosthodontic status amongst an institutionalized elderly dentate population in China. Materials and methods A sample of 512 elders living in eight nursing homes in Qingdao was categorized based on a hierarchical dental functional classification system with and without tooth replacements. Masticatory disability scores (MDSs) were analyzed using multiple regression models with only age, and age and dentition variables for participants having ≥ 10 natural and those having < 10 natural teeth in each jaw. Results Overall, associations between MDS and age, number of teeth, and number of teeth replaced by dental prostheses were identified. For participants having ≥ 10 natural teeth in each jaw, no significant associations between MDS and age and dental and prosthodontic status were found. Participants having < 10 natural teeth in each jaw had higher MDS (increasing chewing difficulties) at higher ages. However, when “premolar region sufficient” and “molar region sufficient” were included, MDS was not associated with age, but with these dentition variables. For participants having ≥ 10 teeth including prosthodontically replaced teeth in each jaw, age was the only variable associated with MDS. For participants having < 10 teeth including teeth replaced in each jaw, the significant factor was “premolar region sufficient.” Overall, lower MDS was associated with increasing number of teeth, as well as with increasing number of teeth replaced by dental prostheses. Conclusions In this population of institutionalized dentate elderly, masticatory ability was significantly associated with dental and prosthodontic status. Clinical relevance For institutionalized elderly, having less than ten natural teeth in each jaw is associated with chewing problems. Most important dentition factor is the presence of three to four premolar pairs. Teeth added by partial removable dental prostheses compensate impaired masticatory ability due to tooth loss for 50% compared to natural teeth.

Abstract
OBJECTIVE This study aimed to examine relevant factors for subjective and objective assessment of masticatory functions and elucidate any differences between the two methods. BACKGROUND Previous studies have reported that the results of subjective and objective assessment of masticatory function in older people do not necessarily agree. MATERIALS AND METHODS This study included 487 community-dwelling Japanese older people (205 male and 282 female; mean age 74.1±6.3 years) who participated in a comprehensive geriatric health examination. Basic information (gender and age), higher level of competence in daily living, depression, subjective masticatory function (SMF) and objective masticatory function (OMF) assessments, cognitive function, skeletal muscle mass, handgrip strength, gait speed and oral status (number of remaining and functional teeth, mouth dryness and occlusal force) were recorded. RESULTS Multiple logistic regression analysis showed that depression (odds ratio [OR]: 1.181, 95% confidence interval [CI]: 1.094-1.275), mouth dryness (OR: 2.037, CI: 1.212-3.423) and occlusal force (OR: 0.997, CI: 0.996-0.999) were significantly associated with SMF, whereas higher level of competence in daily living (OR: 0.730 CI: 0.586-0.910), skeletal muscle mass (OR: 0.521 CI: 0.283-0.960), number of functional teeth (OR: 0.862 CI: 0.775-0.959), number of remaining teeth (OR: 0.868 CI: 0.810-0.930) and occlusal force (OR: 0.994, CI: 0.991-0.998) were associated with OMF. CONCLUSION Subjective masticatory functionSMF and OMF were associated with different factors, suggesting that both mental and physical factors should be taken into consideration when treating decreased masticatory function.

Abstract
Background Masticatory functioning alters with age. However, mastication has been found to be related to, for example, cognitive functioning, food intake, and some aspects of activities of daily living. Since cognitive functioning and activities of daily living show a decline in older adults with dementia, improving masticatory functioning may be of relevance to them. A possible way to improve mastication may be showing videos of people who are chewing. Observing chewing movements may activate the mirror neuron system, which becomes also activated during the execution of that same movement. The primary hypothesis is that the observation of chewing has a beneficial effect on masticatory functioning, or, more specifically, masticatory ability of older adults with dementia. Secondary, the intervention is hypothesized to have beneficial effects on food intake, cognition, activities of daily living, depression, and quality of life. Methods/Design An adjusted parallel randomized controlled trial is being performed in dining rooms of residential care settings. Older adults with dementia, for whom also additional eligibility criteria apply, are randomly assigned to the experimental (videos of chewing people) or control condition (videos of nature and buildings), by drawing folded pieces of paper. Participants who are able to watch each other’s videos are assigned to the same study condition. The intervention takes place during lunchtime, from Monday to Friday, for 3 months. During four moments of measurement, masticatory ability, food intake, cognitive functioning, activities of daily living, depression, and quality of life are assessed. Tests administrators blind to the group allocation administer the tests to participants. Discussion The goal of this study is to examine the effects of video observation of chewing on masticatory ability and several secondary outcome measures. In this study, the observation of chewing is added to the execution of the same action (i.e., during eating). Beneficial effects on masticatory ability, and consequently on the other outcome measures are hypothesized. The intervention may be easily integrated into daily care, and might add to the lives of the increasing number of older adults with dementia by beneficially influencing multiple daily life functions. Trial registration NTR5124. Registration date: 30 March 2015.

Abstract
Previous studies have identified various factors related to masticatory performance. This study was aimed to investigate variations and impacts of factors related to masticatory performance among different occlusal support areas in general urban population in Japan. A total of 1875 Japanese subjects (mean age: 66·7 years) were included in the Suita study. Periodontal status was evaluated using the Community Periodontal Index (CPI). The number of functional teeth and occlusal support areas (OSA) were recorded, and the latter divided into three categories of perfect, decreased and lost OSA based on the Eichner Index. Masticatory performance was determined by means of test gummy jelly. For denture wearers, masticatory performance was measured with the dentures in place. The multiple linear regression analysis showed that, when controlling for other variables, masticatory performance was significantly associated with sex, number of functional teeth, maximum bite force and periodontal status in perfect OSA. Masticatory performance was significantly associated with number of functional teeth, maximum bite force and periodontal status in decreased OSA. In lost OSA, masticatory performance was significantly associated with maximum bite force. Maximum bite force was a factor significantly influencing masticatory performance that was common to all OSA groups. After controlling for possible confounding factors, the number of functional teeth and periodontal status were common factors in the perfect and decreased OSA groups, and only sex was significant in the perfect OSA group. These findings may help in providing dietary guidance to elderly people with tooth loss or periodontal disease.

Abstract
There are numerous reports on the relationship between regular utilization of dental care services and oral health, but most are based on questionnaires and subjective evaluation. Few have objectively evaluated masticatory performance and its relationship to utilization of dental care services. The purpose of this study was to identify the effect of regular utilization of dental services on masticatory performance. The subjects consisted of 1804 general residents of Suita City, Osaka Prefecture (760 men and 1044 women, mean age 66.5 ± 7.9 years). Regular utilization of dental services and oral hygiene habits (frequency of toothbrushing and use of interdental aids) was surveyed, and periodontal status, occlusal support, and masticatory performance were measured. Masticatory performance was evaluated by a chewing test using gummy jelly. The correlation between age, sex, regular dental utilization, oral hygiene habits, periodontal status or occlusal support, and masticatory performance was analyzed using Spearman's correlation test and t-test. In addition, multiple linear regression analysis was carried out to investigate the relationship of regular dental utilization with masticatory performance after controlling for other factors. Masticatory performance was significantly correlated to age when using Spearman's correlation test, and to regular dental utilization, periodontal status, or occlusal support with t-test. Multiple linear regression analysis showed that regular utilization of dental services was significantly related to masticatory performance even after adjusting for age, sex, oral hygiene habits, periodontal status, and occlusal support (standardized partial regression coefficient β = 0.055). These findings suggested that the regular utilization of dental care services is an important factor influencing masticatory performance in a Japanese urban population.

Abstract
Objective: The aim of the present study was to elucidate the influence of self-rated masticatory ability on independent living in community-dwelling older adults. Method: A total of 1,377 subjects aged 65 and over who lived in Kumamoto City, Japan were participated in a survey to investigate critical factors for self-reliance in older adults. In this study, we defined independent life in older adults as self-perceived adequate health without long-term care certification. Logistic regression analysis was used to assess self-perceived masticatory ability in relation to the independent life. Results: The population with adequate self-rated masticatory ability included a significantly higher proportion of subjects with good self-perceived health without long-term care (72.7%) than the remaining subjects (27.3%). A logistic regression analysis revealed that there was significant relationship between subjective adequate mastication and living a self-reliant healthy life (p < .001). Conclusion: Our results showed that satisfactory masticatory function was positively related to a self-reliant life with subjective healthy conditions in community-dwelling older adults, which was associated with an extended active life expectancy.

Abstract
AIM In this study, we investigated the effect of differences in periodontal status in the masticatory performance of dentate subjects with the same occlusal supporting area. MATERIALS AND METHODS The subjects of the analysis were classified into those of Eichner A1-3 (n = 1094) and Eichner B1-4 (n = 529). Subjects' periodontal status was evaluated on the basis of the Community Periodontal Index (CPI). The number of functional teeth and occlusal support were investigated, the latter on the basis of the Eichner Index. Furthermore, masticatory performance was investigated by means of test gummy jelly. For each group, periodontal status was classified in two different ways, either with/without moderate periodontitis (CPI Code ≤2/≥3) or with/without severe periodontitis (CPI Code ≤3/4), and masticatory performance was compared between the various groups. RESULTS In subjects who were Eichner A1 and B3, masticatory performance was significantly lower in subjects with moderate periodontitis compared with those without, and in subjects with severe periodontitis compared with those without. CONCLUSION Periodontal disease affects masticatory performance not only if occlusion is established by natural dentition with no tooth loss but also if occlusal support has decreased.

Abstract
BACKGROUND Although relevant for health policy, so far only little is known about the extent to which persons avoid dental attendance because of associated costs. OBJECTIVES To examine the cost-relatedness of dental non-attendance in various older adulthood populations. MATERIAL AND METHODS Secondary analyses were conducted of data from wave 1 of the Survey of Health, Ageing, and Retirement in Europe (SHARE), which includes unique information on recent dental non-attendance and care foregone due to costs by persons aged 50+ from eleven European countries and Israel. Multivariate logistic regression analysis was used to detect differences in the extent to which dental non-attendance is attributable to associated costs. RESULTS The study sample comprised 13 935 persons who did not access dental care within the past year. Levels of cost-related non-attendance differed between the twelve examined countries, ranging from 6.8% in Israel to 0.5% in Austria. Cost-related non-attendance was 47% less likely among persons with good as compared to compromised chewing ability (Odds Ratio: 0.53; 95% CI: 0.43-0.66). Cost-related non-attendance was 33% less likely among persons with tertiary as compared to (pre-) primary educational attainment (Odds Ratio: 0.67; 95% CI: 0.47-0.96). Cost-related dental non-attendance was significantly more likely among persons with low levels of general health (Odds Ratio for lowest vs. highest level of general health: 3.05; 95% CI: 1.88-4.95). CONCLUSIONS The findings of the present study suggest that a relatively small proportion of dental non-attendance in older adulthood is cost-related. For specific population subgroups in various countries, however, dental care costs may still pose a relevant barrier to dental care.

Abstract
Objectives This study aimed to assess chewing ability related to dental status. Material and methods One thousand four hundred sixty-two Chinese subjects over 40 years, dentate in both jaws, were categorized in a hierarchical functional classification system with and without tooth replacements. Chewing ability was analyzed using multivariable logistic regression including five dental conditions (≥10 teeth in each jaw’; ‘complete anterior regions’; “sufficient premolar regions’ (≥3 posterior occluding pairs (POPs)); ‘sufficient molar regions’ (bilaterally ≥1 POP); and tooth replacement), adjusted for six background variables. Likelihood ratios for chewing problems were assessed at each level of the hierarchical classification system based on these dental conditions. Results Seventy-eight to 91 % of subjects reported no or minor chewing problems. The conditions ‘≥10 teeth in each jaw’, and ‘complete anterior regions’ were not associated, whereas ‘sufficient’ premolar regions’ and ‘sufficient molar regions’ were associated with chewing problems (Ors, 0.33–0.58). If classified hierarchically, the condition ‘≥10 teeth in each jaw’ was relevant for chewing problems (likelihood ratios 3.3–3.7). ‘Sufficient premolar region’ and ‘sufficient molar region’ were relevant to reduce the likelihood ratios for having chewing problems (both approximately with a factor 2), both for soft and for hard foods. Subjects with artificial teeth added had similar chance for chewing problems compared to counterparts with natural teeth only. However, if comparing replaced teeth with natural teeth, subjects with tooth replacement showed higher chance for chewing problems. Conclusions Chewing ability was strongly associated with dental conditions. Clinical relevance The presence of at least 10 teeth in each jaw had highest impact on chewing ability.

Abstract
OBJECTIVES We sought to determine the extent to which early life conditions and adverse life events impact chewing ability in middle and later adulthood. METHODS Secondary analyses were conducted based on data from waves 2 and 3 of the Survey of Health, Ageing, and Retirement in Europe (SHARE), collected in the years 2006 to 2009 and encompassing information on current chewing ability and the life history of persons aged 50 years or older from 13 European countries. Logistic regression models were estimated with sequential inclusion of explanatory variables representing living conditions in childhood and adverse life events. RESULTS After controlling for current determinants of chewing ability at age 50 years or older, certain childhood and later life course socioeconomic, behavioral, and cognitive factors became evident as correlates of chewing ability at age 50 years or older. Specifically, childhood financial hardship was identified as an early life predictor of chewing ability at age 50 years or older (odds ratio = 1.58; 95% confidence interval = 1.22, 2.06). CONCLUSIONS Findings suggest a potential enduring impact of early life conditions and adverse life events on oral health in middle and later adulthood and are relevant for public health decision-makers who design strategies for optimal oral health.

Abstract
Masticatory function can be evaluated objectively as the capacity of an individual to fragment solid food after a fixed number of chewing cycles, the so-called masticatory performance (MP). The objective of this study was to evaluate the reliability of four different test materials (Optosil, Optocal, Zetapuls, and Perfil) and five disinfection protocols by aspersion and immersion (no disinfection, 2% glutaraldehyde, 2% chlorhexidine, 5.25% sodium hypochlorite, and 70% alcohol) on the MP, determined at three moments (24 hours, 15 and 60 days) after storing the fragmented blocks. MP was evaluated by calculating X50 through the sieving technique and the Rosim-Ramler equation. The weight and microbiologic count (colony forming units, CFUs) of chewed blocks were measured to identify any variations that would make MP determination unfeasible. Differences in MP were observed among the materials (p < 0.01). Perfil presented the highest X50 value (worst MP determination), followed by Zetaplus (both p < 0.05), Optosil, and Optocal (both p > 0.05). The time and disinfection type had no influence on MP (p > 0.05). The number of CFUs differed between the nondisinfected group and all other disinfection groups at all time points (p < 0.01). No other significant difference in CFU count between disinfection groups was observed. In conclusion, disinfection did not alter the reliability of the test materials for the MP calculation for up to 60 days.

Abstract
The aim of this cross-sectional study was to assess the factors associated with the impact of oral health on the quality of life in a sample of 504 Brazilian independent elderly. Data collection included oral examinations and structured interviews. The simplified form of the Oral Health Impact Profile (OHIP-14) was used to measure OHRQoL. Information on sociodemographic characteristics, use of dental services, and subjective measures of health was collected. Poisson regression within a hierarchical model was used to data analyses. The following variables were associated with a negative impact on OHRQoL: female gender (PR = 1.40; CI 95%: 1.11-1.77); lower class (PR = 1.58; CI 95%: 1.13-2.20); up to 3 occluding pairs of posterior teeth (PR = 1.88; CI 95%: 1.13-3.14); at least one untreated caries (PR = 1.28; CI 95%: 1.06-1.54); curative reasons for the last dental appointment (PR = 1.52; CI 95%: 1.15-2.00); poor self-perception of oral health (PR = 2.49; CI 95%: 1.92-3.24); and poor perception of dental care provided (PR = 1.34; CI 95%: 1.12-1.59). The younger elderly also noticed this negative impact. These findings showed that the clinical, sociodemographic, and subjective factors evaluated exerted a negative impact on OHRQoL in elderly people. Health authorities must address all these factors when planning interventions on oral health for this population.

Abstract
PURPOSE To describe variations in chewing abilities of elderly populations in different European countries. METHODS We used data from the Survey of Health, Ageing, and Retirement in Europe (SHARE Wave 2) and estimated a series of multivariate logistic regression models in order to analyse variations in self-reported ability to bite and chew on hard foods by persons aged 50+ from 14 European countries (P < 0.05). RESULTS Abilities to bite and chew on hard foods are comparably high in Sweden, Switzerland and the Netherlands but comparably low in Spain, Denmark, France, Greece, Belgium, Italy, Czechia, and Poland. Median levels are observed in Austria, Germany, and Ireland. CONCLUSIONS The best chewing abilities seem to exist amongst elderly populations in Sweden, Switzerland, and the Netherlands but comparably low chewing abilities appear to prevail amongst those in Spain, Denmark, France, Greece, Belgium, Italy, Czechia, and Poland. Future research is encouraged to identify the exact causes and consequences of such disparities in oral health.

Abstract
OBJECTIVES The aim was to assess the prevalence of osteoarthrosis (OA) in the temporomandibular joint (TMJ) in a sample of older people by use of contrast agent-enhanced MRI. METHODS 30 patients (73-75 years old) were drawn from a representative sample and were examined clinically. The shape of the condyle was assessed using gadolinium-enhanced MR images, which were evaluated by two independent raters. Statistical assessment was performed by using descriptive statistics, the chi(2) test and kappa statistics. RESULTS Agreement between raters was excellent with respect to the presence/absence of OA (kappa = 0.8). Only one subject reported pain in a TMJ. Fine and/or coarse crepitus was not heard in any subject. MRI showed that 70% displayed signs of OA in at least one TMJ. There were no gender-related differences in the prevalence of OA (P > 0.05). CONCLUSION Gadolinium-enhanced MRI showed that OA of the TMJ is common in older people (70%), although the prevalence of clinical signs of OA is very low.

Abstract
OBJECTIVE The aim of this study was to assess the association of chewing ability to oral health-related quality of life (OHRQoL) measured by the Oral Health Impact Profile-14 (OHIP-14) controlling for clinical oral health status, self-reported health status, demographic factors, and socioeconomic conditions among community-dwelling and institutionalized Korean elders. METHODS This cross-sectional study comprised a sample of 307 community-dwelling and 102 institutionalized people over the age of 60, using a cluster sampling procedure. A questionnaire was implemented and a clinical oral examination was completed for each subject. The outcome variable of interest was the OHIP-14 score, and its associations with chewing ability, objective oral health status, self-reported health status, demographic factors, and socioeconomic conditions were assessed. Because of highly-skewed distribution of the OHIP-14 scores, nonparametric analytic methods were used. The final model was developed using a multivariable two-level logistic regression model for a dichotomized OHIP-14 score to account for the cluster sampling method applied to this study. RESULTS The mean age of the participants was 75.4 years, with 67.7% being women. The median OHIP-14 score was 7. Negative oral health impacts were experienced fairly often or very often by a total of 36.4% of elderly. In the final model, elders who could chew none to three and four to six foods among seven indicator foods were 3.4 (P = 0.010) and 2.0 (P = 0.040) times more likely, respectively, to have worse OHRQoL compared with elders who could chew all seven food types. Also significant associations with worse OHRQoL were shown for being concerned about oral health [Odds Ratio (OR) = 4.9, P = 0.002], fair or better self-reported oral health (OR = 0.12, P = 0.002), very good/good self-reported general health (OR = 0.38, P = 0.008), being married (OR = 2.0, P = 0.054), and having a favourable economic status (OR = 0.43, P = 0.042). CONCLUSIONS This study showed highly significant association between chewing ability and OHRQoL measured by the OHIP-14 score after controlling for related factors. Amelioration of chewing ability might independently contribute to improving the OHRQoL of elders.

Abstract
BACKGROUND There are few studies assessing the importance of oral status, particularly tooth loss, edentulism and satisfaction with mastication, on the perception of quality of life (qol) in general. The objective of this study was to evaluate if oral status was associated with lower ratings in the WHO Quality of Life Questionnaire-Brief Version (WHOQOL-BREF) domains. METHODS In this cross-sectional study, a random sample of 872 Southern-Brazilians aged 60 years or more was evaluated using a structured questionnaire to assess sociodemographic data, qol (WHOQOL-BREF), and depressive symptoms (Geriatric Depression Scale). Oral examinations assessing the number of teeth and saliva flow were performed. Additionally, participants were asked to rate their satisfaction with the ability to chew. Correlates of poorer qol (i.e. values of the WHOQOL-BREF < or = median) were assessed by means of multivariate logistic regressions. RESULTS Poorer qol in the physical domain was associated with increasing age, income, living in rural areas, >2 chronic conditions, intake of medications, depressive symptoms, edentulism, and reporting difficulty for chewing food. Poorer qol in the psychological domain was associated with income, schooling, >2 chronic conditions, intake of medications, depressive symptoms, and difficulty for chewing. Poorer qol in the environment domain was associated with income, living in urban areas, depressive symptoms, and difficulty for chewing. Poorer qol in the social relations domain was associated with living in urban areas, depressive symptoms, and difficulty for chewing. CONCLUSION In the studied population, oral status was associated with the perception of quality of life in general.

Abstract
To determine the prevalence of edentulism in adults aged 18 years and older in Mexico and to describe its distribution in 20 of the 32 States in Mexico, highlighting the experience in the WHO age groups. A secondary analysis of the National Performance Evaluation Survey 2002-2003 (representative at the state level and part of the Word Health Survey) was undertaken. The sample design was probabilistic, stratified and through conglomerates. Data on dental conditions were available only for 20 of the 32 states of Mexico, leading to a total of 24 159 households (N = 54 638 654). The percentage of edentulism was determined as the proportion of subjects that self-reported complete loss of teeth. Data were analyzed using the SVY module for complex surveys in STATA 8.2. The mean age was 41.3 +/- 17.0 years (range 18-99). An estimated 6.3% (N = 3 437 816) of the population > or =18 years was edentulous. Lowest prevalences were observed in the states of Tlaxcala, Puebla and the Estado de Mexico with 3.4%, 3.8% and 4.5%, respectively. Highest prevalences were observed in San Luis Potosí, Colima, and Michoacán with 10.3%, 10.2% and 10.1%, respectively. Following the WHO age groups, the prevalence ranged from 2.4% in the 35-44 group through 25.5% in the 65-74 group. No obvious association between socio-economic and socio-demographic indicators at the state level and prevalence of edentulism was found. The prevalence of complete tooth loss observed in the present study varied greatly across states, although no straightforward association was found with socio-economic and socio-demographic indicators at the state level. This study could serve as a baseline to enable future evaluations of the oral status of Mexican adults and elders, following WHO age groups.

Abstract
The objectives of this study were to develop and evaluate the validity and reliability of a new index to assess difficulty in eating certain foods among older southern Chinese people. The Index of Eating Difficulty (IED) was developed using a Guttman scaling analysis. After two pilot studies in which subjects were asked to grade 39 typical, frequently eaten Chinese foods, 10 of the 39 foods were selected and divided into five groups based on their texture and frequency of being eaten by older people. In the main study, 1229 Chinese generally healthy subjects aged 55 years and above, attending routine health checks in the Check-up Centre of the First Affiliated Hospital of Guangxi Medical University, Nanning of Guangxi province, China were interviewed to psychometrically test the index. Content, face and criterion validity, coefficients of reproducibility and scalability and test-retest reliability were tested. For criterion validity, the index was significantly associated with three other established eating difficulty measures, namely, general eating difficulty, dissatisfaction with chewing ability and oral impact on daily performances eating scores (P < 0.001 for all tests). The coefficients of reproducibility and scalability were 0.99 and 0.89, respectively. Weighted kappa for test-retest reliability was 0.89. The present results indicate that the IED is a valid and reliable measure to be used among older southern Chinese people.
