Dietary factors in relation to the risk of cognitive impairment and physical frailty in Chinese older adults: a prospective cohort study.

PURPOSE: The study aimed to investigate the independent associations of dietary factors with cognitive impairment (CI) and physical frailty (PF) among Chinese older adults. METHODS: This study included 10,734 participants (mean age = 78.7 years) free of CI and PF at baseline from the Chinese Longitudinal Health Longevity Survey. Dietary intake was collected using a simplified food frequency questionnaire every 3-4 years. The Chinese version Mini-Mental State Examination was used to assess cognition function, participants with a score below 18 were defined as CI. PF was defined using the activities of daily living, instrumental activities of daily living, and functional limitation-related questions. The outcome was defined as the first onset of either CI or PF. Competing risk models were used to estimate the corresponding hazard ratios (HRs) and the 95% confidence intervals (95% CIs). RESULTS: During the study follow-up (mean = 8.1 years), a total of 1220 CI cases and 1451 PF cases were newly identified. Higher frequency of fruits intake was associated with a lower hazard of CI (HR = 0.75, 95% CI 0.58-0.97), whereas higher intake of preserved vegetables demonstrated an opposite association (HR = 1.23, 95% CI 1.07-1.42). In terms of PF, we observed a lower risk associated with higher meat and poultry intake (HR = 0.72, 95% CI 0.61-0.88). In particular, a significant protective association of fish and aquatic products intake with PF was observed among participants with ≥ 28 natural teeth (HR = 0.52, 95% CI 0.27-0.99). CONCLUSION: Our findings suggest divergent roles of major dietary factors in the development of CI and PF among Chinese older adults.

Estimated economic costs of dental implants among older South Korean adults, 2015-2018.

OBJECTIVE: Dental implants are a considerable financial burden for elderly people and their caregivers. This study aimed to calculate the estimated economic costs of dental implants on the Korean older population. MATERIALS AND METHODS: The economic costs of dental implants for adults aged 75 years and older were estimated from a societal perspective, considering both direct and indirect expenditures. We used data from the Korean National Health Insurance Service for the period 2015-2018 to estimate the medical costs. Noninsured medical costs were estimated from research on medical expenses by the National Health Insurance Review and Assessment Service. Indirect costs related to transportation fees and time loss were obtained. The Cochran Armitage trend test was performed to examine the trend of the economic burden of dental implants. RESULTS: The estimated economic costs showed from 2015 to 2018 (total costs: $26.54-55.66 million, total costs after discount: $17.11-39.56 million). Direct costs, including insured and noninsured medical costs, represented from $25.81 to $47.03 million. Indirect costs, including transportation and time costs, ranged from $0.73 to $1.63 million. The impact of the total dental implant costs was 0.0018%-0.0034% of the Korean annual gross domestic product and 1.03%-1.59% of the annual total costs of dental care benefits. CONCLUSIONS: The estimated economic burden of dental implants significantly increased from 2015 to 2018 in older South Korean adults. These results will provide a foundation and guidance for further health economic studies on the burden of dental implants in the elderly population.

Oral frailty among dentate and edentate older adults in long-term care.

BACKGROUND: The objectives of this study were to compare oral frailty (OFr) among edentate and dentate older adults living in long-term care facilities (LTCF) and to clarify how edentulism and oral disease burden (ODB) of dentate older adults are associated with OFr. METHODS: The population of this study comprised 94 edentate and 209 dentate residents in LTCF in Helsinki, Finland, who had previously participated in a nutritional study. The participants underwent a clinical oral examination. The dentate residents were further divided into three ODB groups based on asymptotic dental score. The edentate and different ODB groups were compared with each other regarding demographics and oral and medical findings. OFr was defined as ≥ 2 of following: having a diet of soft/pureed food, residue of food in the oral cavity, inability to keep the mouth open during examination, unclearness of speech, dry mouth. The association between OFr and edentulousness and various levels of ODB was analyzed by a multivariate logistic model. RESULTS: Participants with low ODB had significantly less OFr than their edentate peers (p = 0.009). Furthermore, the edentate and dentate with high ODB had similar odds for OFr. CONCLUSIONS: Edentulousness and high ODB are equally harmful conditions and may predispose to OFr. This study suggests that maintaining healthy natural teeth and good oral health (low ODB) may protect against OFr. TRIAL REGISTRATION: The Ethics Committee of the Hospital District of Helsinki and Uusimaa approved the protocols for the nutritional status and oral healthcare studies and the merging of the data, including patient medical records (Register number HUS/968/2017).

To assess the knowledge, attitudes, and confidence of caregivers and administrators towards the oral health of nursing home residents in San Antonio, Texas.

OBJECTIVE: The primary objective of this research was to use qualitative methods to assess the knowledge, attitudes, and confidence of caregivers in their ability to provide oral hygiene assistance to residents. The secondary objective was to assess the knowledge and attitude of administrators on the provision of oral hygiene assistance for residents, and their confidence in caregivers' ability to provide oral hygiene assistance to nursing home residents in San Antonio, Texas. METHODS: A semi-structured interview guide was used to conduct face-to-face interviews with seven caregivers and twelve administrative staff from ten nursing homes in San Antonio, Texas. Employees in nursing homes who are caring for residents are referred to as caregivers and those whom they care for are referred to as nursing home residents. One survey instrument was developed for the caregiver's knowledge, attitude, and confidence toward providing oral health care, and another to assess the administrator's knowledge, attitude, and confidence in caregivers providing oral care for nursing home residents. The interviews were recorded, transcribed, and coded for thematic content. RESULTS: The findings revealed that caregivers and administrators had adequate knowledge of the connection between oral and systemic health. The administrators were confident that caregivers were adequately trained to provide oral hygiene care for residents. Caregivers had a positive attitude toward the importance of good oral health. They regularly assessed the residents' oral health, but due to time constraints, staffing shortages, and other competing tasks providing oral health care to the residents was challenging. Most caregivers were confident in their skills in providing oral care for the residents since 85.6% agreed. On the contrary, almost half of the administrators were confident that caregivers have the necessary skills to provide oral care for residents, while 41.7% were unsure. CONCLUSIONS: The study gave a broader insight into the provision of oral care in nursing home residents from the perspectives of caregivers and administrative staff. Administrators must provide caregivers with adequate training and time so they can provide adequate oral health care for the residents.

Physical frailty intensifies the positive association of oral frailty with poor global cognitive function and executive function among older adults especially for females: a cross-sectional study.

BACKGROUND: Oral frailty is reported to increase the risk of new onset of mild cognitive impairment. Whereas, the association of oral frailty with cognition among older adults in both physical frail and non-physical frail status has not been sufficiently explored, and whether there are sex differences in the association is unclear. This study investigated the association of oral frailty and physical frailty with global cognitive function and executive function among older adults, as well as the sex differences in such association. METHODS: This cross-sectional study included 307 participants aged ≥ 60 years old from communities between June 2023 and August 2023, in Nanjing, China. Global cognitive function and executive function were assessed by using the Montreal Cognitive Assessment (MoCA) and Trail Making Tests A (TMT-A), respectively. Oral frailty was identified by the combination of natural tooth, Oral Frailty Index-8 (OFI-8), and oral diadochokinesis. Physical frailty was measured by using Fried phenotype model which contained 5 criteria: unintentional weight loss, weakness, exhaustion, slowness, and low physical activity. Multiple linear regression analyses for overall participants and stratified by sex and presence or absence of physical frailty were performed, respectively, to examine the association between oral frailty and cognitive functions. RESULTS: The median age of participants was 70 years old. The study included 158 (51.5%) females, 53 (17.3%) individuals with physical frailty, and 65 (21.2%) participants with oral frailty. After adjustment, the association between oral frailty and global cognitive function was observed in the physical frailty group (B = -2.67, 95% Confidence Interval [CI]: -5.27 to -0.07, p = 0.045) and the females with physical frailty (B = -4, 95% CI: -7.41 to -0.58, p = 0.024). Oral frailty was associated with executive function in overall participants (B = 0.12, 95% CI: 0.01 to 0.22, p = 0.037), physical frailty group (B = 23.68, 95% CI: 1.37 to 45.99, p = 0.038). In the adjusted models, oral frailty was significantly associated with executive function in all females (B = 0.21, 95% CI: 0.05 to 0.36, p = 0.009), in females without physical frailty (B = 0.19, 95% CI: 0.02 to 0.36, p = 0.027), and in females with physical frailty (B = 48.69, 95% CI: 7.17 to 90.21, p = 0.024). CONCLUSIONS: Physical frailty intensifies the positive association of oral frailty with poor global cognitive function and executive function among older adults, particularly among females. It is ponderable to consider sex differences and facilitate the management of physical frailty when it comes to promoting cognitive health based on the perspective of oral health among older adults.

Relationships between oral function, dietary intake and nutritional status in older adults aged 75 years and above: a cross-sectional study.

BACKGROUND: Malnutrition is related to impaired oral health and function that causes poor dietary intake, declining the general health of older adults. The role of dietary intake in the association between oral function and nutritional status of Chinese older adults (aged 75 and above) was examined in this cross-sectional study. METHODS: Through the randomized cluster sampling method, 267 older adults living in rural areas of Qingdao, Shandong (aged 81.4 ± 4.3, 75-94 years) were chosen as the primary research participants. A Mini Nutritional Assessment - Short Form was used to determine nutritional status, and Food Frequency Questionnaire and 24-hour Food Intake Recall were used to assess dietary intake. The oral function was evaluated by analyzing the teeth, oral problems, bite force, tongue pressure, lip sealing pressure, chewing function questionnaire, whole saliva flow rate, 10-Item Eating Assessment Tool, and water swallow test. RESULTS: Based on the MNA-SF score, it was divided into a well-nourished group and a malnutrition group, with the malnutrition group comprising 40.6% of participants. The participants in the malnutrition group showed a higher rate of xerostomia, lower bite force, tongue pressure, and lip sealing pressure, and higher Chewing Function Questionnaire and 10-Item Eating Assessment Tool scores. Furthermore, their plant fat, iron, cereals and potatoes, vegetables, fruits, and seafood intake were relatively low. The regression model indicated that exercise frequency, stroke, chewing and swallowing function, intake of vegetables and fruits were risk factors for nutritional status of older adults. CONCLUSION: Malnutrition was relatively common among the Chinese older adults aged 75 and above, and it was significantly correlated with exercise frequency, stroke, chewing and swallowing function, and intake of vegetables and fruits. Therefore, nutrition management should be carried out under the understanding and guidance of the oral function and dietary intake of the older adults.

Association between tea types and number of teeth: a cross-sectional study of the Chinese Longitudinal Healthy Longevity Survey.

BACKGROUND: Previous studies have suggested that tea consumption may have a positive impact on oral health. However, the effects of different tea types on oral health remain unclear. Therefore, this study aimed to determine the association between residual teeth and consumption habits of different types of tea (green tea, black tea, oolong tea, and scented tea) in older adults. METHODS: We conducted a secondary analysis using data from the Chinese Longitudinal Healthy Longevity Survey in 2018. In a sample of 6,387 older adults, we performed logistic regression analysis to examine the relationship between persistent tea consumption and oral health according to sex and brushing frequency. The indices for particularly healthy oral health and relative health were set at more than 20 teeth and more than 10 teeth, respectively. RESULTS: The study included 2,725 males and 3,662 females, both aged 65 and older. Among individuals with more than 20 teeth, drinking green tea significantly improved oral health in men (adjusted odds ratio [ORs]: 1.377; 95% confidence interval [CI]: 1.082-1.752) and drinking black tea significantly improved the oral health of women (ORs: 2.349, 95%CI: 1.028-5.366). In the daily brushing group, green tea had a significant beneficial effect on increasing the number of teeth in men and black tea had a significant beneficial effect in women. Among individuals with more than 10 teeth, drinking green tea significantly improved oral health in men (ORs: 1.539; 95% CI: 1.209-1.959) and drinking green tea and scented tea significantly improved the oral health of women (ORs: 1.447, 95%CI: 1.052-1.991; ORs: 1.948, 95%CI: 1.137-3.340). In the daily brushing group, consumption of green tea and black tea had significant beneficial effects on increasing the number of teeth in men, whereas that of green tea, black tea, and scented tea had significant beneficial effects in women. CONCLUSION: Long-term green tea consumption in males and black tea consumption in females were significantly associated with maintaining functional dentition (≥20 teeth). Similarly, long-term green tea consumption in males and green tea and scented tea consumption in females were associated with avoiding severe tooth loss (≥10 teeth). Furthermore, in the daily tooth brushing group, long-term consumption of black tea was associated with avoiding severe tooth loss in both sexes. However, tea consumption alone had no effect on oral health without good brushing habits.

Cross-Sectional Associations between Nutrient Intake and Tooth Decay in Older Australian Men: The Concord Health and Ageing in Men Project.

Poor nutrition is a risk factor for dental decay in younger people. However, except for sugar, it is unclear if this is true in older age groups. The aim of this study was to analyze the possible associations between overall dietary intake of nutrients and diet quality and the presence of dental decay in community-dwelling older men. A cross-sectional analysis of a longitudinal study with a standardized validated diet history assessment and comprehensive oral health examination in 520 community-dwelling men (mean age: 84 years) participating in the Concord Health and Ageing in Men Project. Nutrient reference values were used to determine if individual micronutrients and macronutrients were meeting recommendations. Acceptable macronutrient distribution ranges (AMDRs) were attained for fat and carbohydrate intakes and were incorporated into a dichotomous variable to determine if the participants were consuming a high fat-low carbohydrate diet. Diagnosis of coronal caries was based on visual criteria and inspection and was completed on each of the five coronal surfaces. Root surface caries was textual changes across four root surfaces. This diagnosis was used to categorize participants by the presence and severity of coronal and root caries. The adjusted logistic regression showed not meeting the recommended intakes for thiamin (odds ratio [OR]: 2.32 95% confidence interval [CI] 1.15-4.67), and zinc (OR: 3.33, 95% CI: 1.71-6.48) were associated with presence of severe root decay. Adjusted analysis also showed that participants who were outside the recommended AMDR for fat (OR: 0.61, 95% CI: 0.38-0.98) and those who consumed a high fat and low carbohydrate diet (OR: 0.56, 95% CI: 0.35-0.91) were less likely to have coronal tooth decay. Our study shows associations between micronutrients and macronutrients and coronal and root surface decay. Although this study cannot prescribe causality or be generalized to all older adults, diet has a possible association with dental decay in older men.

Development of a Needs Assessment for Low-income Seniors in Cleveland Ohio: A student-driven Interprofessional Approach.

BACKGROUND AND OBJECTIVE: Older persons with low socioeconomic status in the United States have different and unique health needs compared to younger persons. As part of a student-led, interprofessional partnership, we performed a needs assessment of community dwelling older persons with low socioeconomic status in an urban location within Ohio, USA. METHODS: Three entities participated in the needs assessment: a student-run health clinic, a Federally Qualified Health Center, and an apartment complex of the study population. Health professional students from medical, dental, nursing, social work, nutrition, and physician assistant programs led the needs assessment process. The process consisted of multiple phases, which included preliminary literature review, survey development, data collection, and analysis. The final survey was multidisciplinary, with six content areas covered in 37 items. RESULTS: One hundred nineteen survey responses were received, and multiple areas of need were identified including food insecurity, dental care access, and mental health. 93% of participants had at least one unmet health need and 39% of respondents met our classification for high need. The needs of the local study population had key differences from previously published data in more generalized populations of older community-dwelling individuals in the United States, notably lower utilization of dental care (43% vs. 66%), increased prevalence of possible food insecurity (30% vs. 17%), and increased use of age-appropriate preventive cancer screening services. CONCLUSIONS: Multiple areas of need were successfully identified through a student-led interprofessional needs assessment. Future student teams can address the identified needs, again through interprofessional collaborations. This process may have unique benefits to help build robust community-academic partnerships, while fostering interprofessional collaborative opportunities among healthcare students.

Improving oral hygiene for better cognitive health: Interrelationships of oral hygiene habits, oral health status, and cognitive function in older adults.

OBJECTIVES: To explore the interrelationships between oral hygiene habits, oral health status and cognitive function in older adults. DESIGN: A cross-sectional study. SETTING AND PARTICIPANTS: A total of 371 participants (age 76.79 [7.99] years) were enrolled from June 2020 to November 2021 in an aged care facility. METHODS: Cognitive function was screened using the mini-mental state examination (MMSE) with adjusted cut-off points for age and education. Periodontal status (Biofilm-Gingival Interface index based on periodontal probing depth and bleeding on probing), dental status (plaque, calculus, and caries), and tooth loss were assessed through full-mouth examination. Oral hygiene habits were based on self- or informant-reporting. RESULTS: Poor periodontal status was an associated factor for MCI (OR = 2.89, 95% CI = 1.20-6.95), while multiple tooth loss (OR = 4.90, 95% CI = 1.06 ~ 22.59), brushing teeth less than once a day (OR = 2.88, 95% CI = 1.12 ~ 7.45) and delayed dental visits (OR = 2.45, 95% CI = 1.05 ~ 5.68) were associated factors for cognitive impairment. An indirect effect of brushing teeth ≥2 daily on MMSE score through periodontal status was observed only in older adults without cognitive impairment (Bootstrap-corrected B = 0.17, 95%CI = 0.03 ~ 0.36, SE = 0.08, ß = 0.08). CONCLUSIONS AND IMPLICATIONS: Adequate toothbrushing might prevent cognitive decline indirectly by improving periodontal health only in older adults without cognitive impairment. Multiple tooth loss, infrequent toothbrushing, and delayed dental visits were associated factors for cognitive impairment. Nursing professionals and health care policymakers should advocate for the improvement of basic oral hygiene in older adults, and provide regular professional oral hygiene care for older adults with cognitive impairment. PATIENT OR PUBLIC CONTRIBUTION: The information on oral health habits of this study was based on an interview with the participants or their caregivers during the study period.

REDUCE missed oral healthcare: The outcomes of and learnings from an implementation project in an acute geriatric unit.

Oral healthcare is one of the most missed aspects of fundamental care. Failure to provide reliable and effective daily oral healthcare for older patients can lead to hospital-acquired pneumonias, longer hospital stays, increased health costs, and poor patient experience. The objective of this study was to codesign, implement, and evaluate an oral healthcare intervention for older adults in a geriatric unit. This mixed methods implementation project combined the hospital's quality improvement processes with the i-PARIHS knowledge translation framework. Multilevel facilitation guided the development of multidisciplinary implementation strategies, which were co-designed, tailored, and implemented at the ward and organizational level, targeting: awareness/engagement; clinical guideline development; building workforce capacity; access to appropriate products; patient awareness and support; utilization of multidisciplinary/dental referral pathways; and systematizing oral healthcare documentation. Gaps between evidence-based and current oral healthcare practice were identified through audits of practice and interviews with patients. Interviews and surveys with staff evaluated the feasibility and acceptability of the oral healthcare intervention and the success of implementation strategies. At the conclusion of the project, awareness, attitudes, and capacity of staff had increased, however, we could not demonstrate change in multidisciplinary oral healthcare practices or improvements for individual patients. Despite mixed success, the project informed discussions about including oral healthcare as a national healthcare standard for the acute care sector in Australia. Attempts to address oral healthcare may have started locally, but its impact was through policy change, which will empower health practitioners and managers to support practice change more widely.

A prospective cohort study on factors related to dental care and continuation of care for older adults receiving home medical care.

Information on the effects of dental treatment must be identified and factors that hinder the continuation of dental treatment must be identified to provide appropriate domiciliary dental care (DDC). This study aimed to clarify the treatment outcomes of DDC for older adults and the factors that impede the continuation of such care. This prospective study was conducted at a Japanese clinic specializing in dental care for older adults. The functional status, nutritional status, oral assessment, details of the dental treatment, and outcomes after 6 months of older adults receiving DDC were surveyed. The Oral Health Assessment Tool (OHAT) was used for oral assessment. Cox proportional hazards analysis was used to analyze the factors at the first visit that were associated with treatment continuation. A total of 72 participants (mean age, 85.8 ± 6.9) were included. Twenty-three participants (31.9%) could not continue treatment after 6 months. The most frequently performed procedures were oral care and dysphagia rehabilitation, followed by prosthetic treatment, then tooth extraction. The percentage of participants with teeth that required extraction after 6 months and the total OHAT score decreased significantly. The Barthel Index, Mini Nutritional Assessment Short-Form, and rinsing ability were significantly associated with treatment continuation. Furthermore, instrumental activities of daily living (ADL) and the OHAT "tongue" sub-item were correlated with treatment continuation. In conclusion, DDC improved the oral health status of older adults after 6 months. Factors that impeded treatment continuation were decreased ADL, decreased nutritional status, difficulty in rinsing, and changes in the tongue such as tongue coating.

Factors associated with the oral health status of patients with schizophrenia: A cross-sectional study.

BACKGROUND: Oral function deterioration attributed to ageing and medications is one of the main contributory factors of dysphagia. Therefore, oral health management is essential in older patients with schizophrenia. However, no previous studies have evaluated the oral function in patients with schizophrenia. OBJECTIVE: We surveyed patients with schizophrenia to identify factors associated with ageing-related variations in oral function. METHODS: This cross-sectional study included 34 male patients diagnosed with schizophrenia who were hospitalised at a psychiatric hospital between July and September 2021 and underwent a screening examination during dental care. The survey items included basic information, oral hygiene information, oral (oral diadochokinesis [ODK] and tongue pressure), physical function, and nutritional status. Thirty-six male community-dwelling older individuals were included as controls, and their outcomes were compared with those of patients with schizophrenia. RESULTS: Compared with healthy older adults, patients with schizophrenia demonstrated significantly lower teeth numbers, ODK, and calf circumference (CC) (p < .05). Multiple regression analysis revealed that ODK was associated with age and schizophrenia (p < .05). Conversely, tongue pressure was associated with CC (p < .05), suggesting different factors' association with the parameters indicating decreased oral function. CONCLUSIONS: Our study findings suggest that older patients with schizophrenia have decreased tongue pressure and generalised muscle mass, highlighting the need to manage oral function. Interventions for tongue pressure were more strongly associated with muscle mass and could be easier to manage than those with disease-dependent changes in ODK. TRIAL REGISTRATION: Retrospectively registered.

Prevalence and risk factors of frailty among older family caregivers.

AIM: The aim of this study was to investigate the prevalence of frailty and identify the demographical and clinical factors associated with frailty among older family caregivers. METHOD: The participants of this cross-sectional study were older family caregivers (n = 125) living in Eastern Finland. Data on functional and cognitive status, depressive symptoms, nutritional status, medication, chronic diseases, stroke, and oral health were obtained. The Mini Nutritional Assessment (MNA) was used to evaluate nutritional status. Frailty status was evaluated using the abbreviated comprehensive geriatric assessment (aCGA) scale. RESULTS: Seventy-three percent of caregivers were identified as frail. According to multivariable logistic regression, cataract, glaucoma, or macular degeneration and the MNA score were predictors of frailty. After adjusting for age, gender, and number of own teeth, the MNA score remained a significant predictor of frailty (adjusted OR = 1.22, 95% CI = 1.06, 1.41). As the MNA scores decreased (meaning poorer nutritional status), the risk of frailty increased. CONCLUSIONS: The present study showed that frailty is prevalent among older family caregivers. Recognising older family caregivers with frailty or at risk of frailty is vital. It is essential to acknowledge vision problems' role in frailty and to monitor and support the nutritional status of family caregivers regularly to prevent frailty development.

Exploring the attitudes of general dental practitioners to providing dietary advice alongside oral rehabilitation for older adults.

OBJECTIVE: We aimed to capture General Dental Practitioners' (GDPs) views on delivering dietary advice to older adults in combination with treatment to replace missing teeth and identify solutions to help inform the development and implementation of future dietary interventions within primary dental care. BACKGROUND: As natural teeth are lost, older adults may need to choose softer, more manageable foods which might be of lower nutrient density. Previous research has indicated that prosthodontic rehabilitation can improve masticatory function but not the intake of nutrients, highlighting a potential need for a combined approach of oral rehabilitation and dietary counselling. MATERIALS AND METHODS: Semi-structured telephone interviews were conducted with a purposive sampling strategy of 12 GDPs. Interviews were digitally recorded and transcribed verbatim. An iterative coding process using theme-analytic methods was used. RESULTS: Twelve interviews were conducted with GDPs in the United Kingdom. The themes that emerged from the interviews included: the awareness of the importance of dietary advice among GDPs; the concerns GDPs had on patients' adherence to dietary advice; uncertainty over roles and responsibilities in the provision of dietary advice; and the limited time and remuneration for dietary advice in dental practice. A minor theme identified was the motivation of GDPs to implement dietary advice alongside oral rehabilitation. All reported that they were already providing dietary advice to their patients but that this was limited to caries prevention. CONCLUSION: The GDPs interviewed expressed positive attitudes towards providing dietary advice alongside oral rehabilitation for older adults. However, a lack of confidence, awareness, time and remuneration are barriers to its provision in primary dental care. To facilitate the implementation of dietary advice alongside oral rehabilitation, clear guidance on and training in delivering dietary advice and multidisciplinary cooperation are required.

Food insecurity and its relationship to mental health and oral health in older adults.

BACKGROUND AND OBJECTIVES: Poor oral health disproportionately affects low-income older adults, for whom food insecurity and poor mental health may affect dental health. We explored the associations between food insecurity, mental health, and dental health. Furthermore, we examined whether mental health impacted the associations between food insecurity and dental health. MATERIALS AND METHODS: We conducted a cross-sectional study with a convenience sample of 226 older adults (aged 50+), employing survey and dental screening data. Participants were recruited from seven community-based organisations in Washington State, USA. We calculated descriptive statistics and conducted Chi-square tests, t tests, and logistic regression analyses to assess the associations between aspects of dental health (untreated decay, gum disease, and unmet dental needs), mental health (depression and cognitive function), and food insecurity. RESULTS: In our sample, food insecurity was observed in 28.4%, 40.6% had untreated decay, 31.6% gum disease, and 42.5% unmet dental needs. Food insecurity was associated with a higher occurrence of untreated decay and unmet dental needs. Participants experiencing food insecurity had higher odds of gum disease (aOR = 2.3; 95% CI: 1.1, 5.2) and unmet dental needs (aOR = 3.2; 95% CI:1.4, 7.6). Greater gum disease due to food insecurity was observed among individuals with lower levels of cognitive impairment. CONCLUSION: Food insecurity is associated with poorer oral health among older adults and cognitive function may modify this relationship. These findings underscore the importance of addressing both food insecurity and cognitive impairment as integral components of efforts to improve the oral health of older adults.

Professional dental care and survival rates in long-term care recipients: A cohort study of 1 459 163 individuals in South Korea.

OBJECTIVES: To determine the dental care pattern and survival rates of participants who received long-term care (LTC) and a matched control cohort in South Korea. BACKGROUND: Global ageing trends and the development of superaged societies pose healthcare challenges. South Korea's LTC system aids those with chronic illnesses and disabilities. Despite the link between oral health and systemic diseases, providing dental care in LTC facilities often reflects social neglect. METHODS: We identified 1 459 163 individuals eligible for LTC insurance in the Korean National Health Insurance Service database from July 2008 to 2015 (LTC cohort) and 1 459 544 individuals matched through propensity-score matching (matched cohort). The LTC recipients were further categorised into subgroups based on their care type (institutional, home or mixed care). Population of utilising dental services and the average number of dental visits were counted in each cohort, and the survival rate of the LTC cohort was determined according to dental utilisation. RESULTS: Population of utilising dental services increased steadily in all cohorts except for institutional care, with the highest utilisation (around 30%) observed in the matched cohort. Lower independence in LTC cohorts was associated with lower dental utilisation: 18-27% for home care, 12-18% for mixed care, and 10% for institutional care. The survival rates in the LTC cohort were significantly lower than in the matched cohort (P < .0001), with 28.1% survival in LTC vs 59.3% in the matched cohort. CONCLUSION: Long-term care recipients experience social neglect for oral care, while higher survival rates were observed in those utilised dental services.

Influence of prosthodontic rehabilitation and dietary advice on glycaemic control, nutritional status and oral health-related quality of life of older adults with type 2 diabetes.

OBJECTIVES: This prospective clinical study aimed to determine the influence of oral prosthodontic rehabilitation with partial removable dentures and simplified dietary advice on glycaemic control, nutritional status and oral health-related quality of life (OHRQoL) of older adults with type 2 diabetes. BACKGROUND: Individuals with tooth loss who did not wear complete or partial dentures are more likely to be at nutritional risk, suggesting that using dental prostheses would benefit the re-establishment of an adequate nutritional status and potentially improve quality of life. Nutritional therapy is essential for diabetes prevention, treatment and management, favouring glycaemic control. The literature provides little evidence on the contribution of partial removable dentures to improving diabetes control, nutritional profile and satisfaction in older adults, especially those with type 2 diabetes. MATERIALS AND METHODS: Older individuals diagnosed with type 2 diabetes mellitus, aged 60 years or older and needing oral rehabilitation with partial removable dentures were eligible for this prospective study. The primary outcome measure was glycaemic control, measured by glycated haemoglobin (HbA1c) levels. The Oral Health Impact Profile (OHIP-14) questionnaire and the Mini Nutritional Assessment short-form (MNA-SF) represented secondary outcome measures. These measures were assessed at baseline and 12 months of follow-up after prosthesis delivery, combined with simple dietary advice in pamphlet form. The data were analysed using the Wilcoxon matched-pairs test. RESULTS: Forty-four patients who met the inclusion criteria and required treatment with removable partial dentures were selected for this study, which was carried out for a year. During this period, seven participants declined to participate because they moved to another city. Hence, a final sample of 37 participants (16 men and 21 women, average age of 65.8 years, ranging from 60 to 83 years) were included in the study. No laboratory parameter (HbA1c levels) changed significantly during the investigation. The number of older adults at risk of malnutrition was significantly lower at 12 months than at baseline. Furthermore, nutritional status significantly improved 12 months after prosthodontic treatment combined with dietary advice, and the effect sizes were large. OHRQoL significantly improved after prosthodontic therapy combined with dietary advice. CONCLUSIONS: Prosthodontic treatment with partial dentures associated with simple dietary advice did not influence glycaemic control but improved the nutritional status and OHRQoL of older adults with type 2 diabetes.

Clinically estimated signs of hyposalivation in older adult residents of long-term care.

OBJECTIVE: To assess whether the estimation of clinical signs of hyposalivation is applicable in recognising long-term care facility (LTCF) residents with poor oral health, and which individual characteristics are important in that respect. BACKGROUND: A common inconvenience among older adults, dry mouth, particularly hyposalivation, can cause many complications, such as greater susceptibility to root caries and oral infections, and it can lead to further deterioration of oral health. However, very little is known about the association of clinically assessed signs of hyposalivation with the oral health status of LTCF residents. METHODS: The study sample comprised 362 individuals (dentate n = 266, edentate n = 96) aged 65 or older. The examinations included a questionnaire and clinical oral examination. Participants were categorised into three groups based on clinically assessed oral dryness: normal salivation (n = 83, 22.9%), lower salivation (n = 182, 50.3%) and dry mouth (n = 97, 26.8%). The association between signs of dry mouth with aspects to oral health was evaluated and further tested with logistic regression analysis. RESULTS: The signs of oral dryness were observed among females, those with dementia, and those with longer stays in the current facility. Root caries (odds ratio, OR 1.3) and diagnosis of periodontitis (OR 4.1), together with several individual periodontal parameters, as well as having less than ten occluding pairs of natural teeth (OR 3.5) were associated with dry mouth. Edentate participants showed an increased likelihood of having dry mouth with advancing age, and lesions on the lips were associated with dry mouth with OR 3.0. CONCLUSION: Clinical estimation of signs of oral dryness can be a useful adjunct in evaluating the oral health status of dentate LTCF residents. Poor oral health was a frequent finding, especially among dentate LTCF residents with signs of dry mouth.

Translation and psychometric properties of the Arabic version of the ageism scale for dental students (ASDS-Ar): A multi-institutional validation.

BACKGROUND AND OBJECTIVE: Ageism represents an important barrier to high-quality healthcare for older adults. The present study sought to translate and validate the Arabic version of the Ageism Scale for Dental Students (ASDS-Arabic). MATERIALS AND METHODS: The 27-item ASDS tool was translated from English into Arabic following recommended cross-sectional forward and backward translation guidelines. The translated version was subjected to the content validity ratio (CVR) and sent to dental students in 21 institutes from 10 different Arab countries. Principal components analysis (PCA) was used to assess the dimensionality of the scale, and Cronbach's alpha was used to determine internal consistency reliability. The discriminant validity of the scale was assessed using the independent t-test. Confirmatory factor analysis (CFA) was also undertaken. RESULTS: Based on CVR, three items were removed. The 24-item Arabic version was completed by 3284 dental students. PCA and CFA retained 17 items in six components, explaining 50.3% of the total variance, with acceptable reliability, validity and discrimination. The first component "Adherence of older patients with dental treatment and instructions," included four items with a Cronbach α of 0.64 and scored 4.3 ± 0.8. The second component "Feasibility of the treatment plan," included three items with a Cronbach α of 0.66 and scored from 2.6 ± 1.2 to 2.9 ± 1.1. The third component "Cost of and responsibility for the dental treatment" included four items with a Cronbach α of 0.47 and scored 4.4 ± 0.8 to 4.5 ± 0.8. The fourth component "Medical history of older patients" included two items with a Cronbach α of 0.70 and scored 4.0 ± 1.0 to 4.1 ± 1.0. The fifth Component "Feeling towards older patients" included two items with a Cronbach α of 0.672 and scored 2.6 ± 1.2 to 2.0 ± 1.4. The sixth Component "Confidence and experience in treating older patients" included two items with a Cronbach α of 0.33 and scored 4.4 ± 1 to 4.6 ± 1. CONCLUSION: This preliminary validation of the ASDS-Ar resulted in a new 17-item scale with six components with acceptable validity, reliability and discrimination.
