Oral health and orofacial pain in older people with dementia: a systematic review with focus on dental hard tissues

Dentists' Approaches to Treatment Decision-Making for People with Dementia: A Qualitative Study

INTRODUCTION

Globally, the number of people living with dementia (PLwD) is projected to increase substantially. Dentists will encounter an increasing number of PLwD retaining natural teeth who need dental care. Dental treatment planning can be complex for PLwD as both oral diseases and dental treatment can be detrimental to patients' oral and social function and comfort. In addition, patients may lack the capacity to make decisions about their treatment, posing further challenges for dentists.

OBJECTIVE

This study aimed to explore dentists' approach to treatment decision-making with or for PLwD.

METHODS

Semistructured one-to-one interviews were completed with 22 dentists between April 2020 and March 2021. Data generation and analysis followed the principles of constructivist grounded theory with data being collected and analyzed simultaneously using a maximum variation sample. Interviews were recorded, transcribed verbatim, and then analyzed, leading to a theoretical understanding of how dentists approach treatment decisions for PLwD.

RESULTS

Four data categories describe dentists' approaches to treatment decision-making for PLwD. Dentists sought to provide individualized care for PLwD. However, they described planning care based on risk-benefit analyses that primarily considered biomedical factors and generic assumptions. There was an underemphasis on the psychological or social implications of dental care or its delivery. Furthermore, while some dentists attempted to involve patients in treatment decisions, they reported fewer attempts to identify the views and preferences of PLwD identified as lacking decisional capacity. In this scenario, dentists reported leading the decision-making process with little regard for patients' known or identified preferences and minimal involvement of PLwD's family.

CONCLUSIONS

Dentists acknowledge the complexity in treatment decision-making for PLwD yet focused heavily on biomedical considerations, with an underemphasis on individuals' preferences and autonomy. Considering psychosocial aspects of care alongside biomedical factors is essential to support holistic person-centered care for this growing patient cohort.

KNOWLEDGE TRANSFER STATEMENT

This study highlighted that dentists may only be considering biomedical aspects of care when considering what treatment is appropriate for people living with dementia. When making or supporting treatment decisions, dentists should explore patients' preferences and actively consider relevant psychosocial factors. These can be actively identified through considered discussions with patients as well as their family members. Gathering this information should support more person-centered and value-concordant decision-making for people living with dementia.

ESPEN guideline on nutrition and hydration in dementia - Update 2024

BACKGROUND & AIMS

Dementia is accompanied by a variety of changes that result in an increased risk of malnutrition and low-intake dehydration. This guideline update aims to give evidence-based recommendations for nutritional care of persons with dementia in order to prevent and treat these syndromes.

METHODS

The previous guideline version was reviewed and expanded in accordance with the standard operating procedure for ESPEN guidelines. Based on a systematic search in three databases, strength of evidence of appropriate literature was graded by use of the SIGN system. The original recommendations were reviewed and reformulated, and new recommendations were added, which all then underwent a consensus process.

RESULTS

40 recommendations for nutritional care of older persons with dementia were developed and agreed, seven at institutional level and 33 at individual level. As a prerequisite for good nutritional care, organizations caring for persons with dementia are recommended to employ sufficient qualified staff and offer attractive food and drinks with choice in a functional and appealing environment. Nutritional care should be based on a written care concept with standardized operating procedures. At the individual level, routine screening for malnutrition and dehydration, nutritional assessment and close monitoring are unquestionable. Oral nutrition may be supported by eliminating potential causes of malnutrition and dehydration, and adequate social and nursing support (including assistance, utensils, training and oral care). Oral nutritional supplements are recommended to improve nutritional status but not to correct cognitive impairment or prevent cognitive decline. Routine use of dementia-specific ONS, ketogenic diet, omega-3 fatty acid supplementation and appetite stimulating agents is not recommended. Enteral and parenteral nutrition and hydration are temporary options in patients with mild or moderate dementia, but not in severe dementia or in the terminal phase of life. In all stages of the disease, supporting food and drink intake and maintaining or improving nutrition and hydration status requires an individualized, comprehensive approach. Due to a lack of appropriate studies, most recommendations are good practice points.

CONCLUSION

Nutritional care should be an integral part of dementia management. Numerous interventions are available that should be implemented in daily practice. Future high-quality studies are needed to clarify the evidence.

Exploring dental treatment decision-making experiences of people living with dementia and family carers

INTRODUCTION

People living with dementia can have complex dental care needs. Dentists and patients should make treatment decisions together, yet some people living with dementia may be unable to make their own decisions about their dental care. Dental treatment decision-making and patients' experiences of this process have not been comprehensively researched.

OBJECTIVE

This study aimed to explore the dental treatment decision-making perspectives and experiences of people living with dementia and their family members.

METHODS

Semi-structured interviews were undertaken with 8 people living with dementia and 17 family caregivers. A constructivist grounded theory approach was adopted, using a maximum variation sample. Qualitative data collection and analysis occurred concurrently. Data underwent initial open coding followed by more focused coding, supported by reflexive memo writing, which supported data categorisation.

RESULTS

People living with dementia reported wanting to be understood as unique individuals with specific needs. All participants described wanting to be actively involved in dental treatment decisions. However, many felt that they were insufficiently involved in treatment decision-making. This perceived underinvolvement meant that some people living with dementia and family members felt the treatment outcomes they sought were neither discussed nor considered.

CONCLUSION

People living with dementia and carers had specific expectations of dental care yet felt passive in decision-making despite their desire to be involved in this process. Dentists should seek to actively establish patients' preferences, regardless of mental capacity and consider these in discussions and decisions about dental treatment.

Effectiveness of fluorides in root caries prevention, Department of Veterans Affairs (2009-2018)

AIMS

The aim of this study was to examine the effectiveness of topical fluorides in prevention of root caries-related treatment in high caries risk Veterans.

METHODS

This retrospective analysis of longitudinal data examined the effectiveness of professionally applied or prescription (Rx) fluoride treatment, in VHA clinics from FY 2009-2018. Professional fluoride treatments included 5% Sodium Fluoride (NaF) varnish (22 600 ppm fluoride), 2% NaF gel/rinse (9050 ppm fluoride), and 1.23% APF gel (12 300 ppm fluoride). The Rx for daily home use was 1.1% NaF paste/gel (5000 ppm fluoride). Outcomes studied were new root caries restorations or extractions and percent of patients with treatment over 1 year. Logistic regressions were adjusted for age, gender, race, ethnicity, chronic medical or psychiatric conditions, number of medication classes, anticholinergic drugs, smoking, baseline root caries treatment, preventive care, and time between first-last restoration in the index year.

RESULTS

Root caries at baseline was associated with a high risk for new root caries. Veterans without root caries during the index year who received a fluoride gel/rinse intervention were 32-40% less likely to receive caries-related treatment for root caries during the follow-up period. Once Veterans had root caries, fluorides did not exhibit a positive effect.

CONCLUSION

In older adults with high caries risk, early fluoride prevention is key, before root caries requires treatment.

Prevalence of orofacial pain in individuals with mild cognitive impairment or dementia: A systematic review and meta-analysis

BACKGROUND

This systematic review investigated the prevalence of orofacial pain in patients with mild cognitive impairment (MCI) or dementia.

MATERIALS AND METHODS

The search was conducted in five databases (Medline (Ovid), Embase (Ovid), CINAHL, Scopus and LILACS), in three grey literature sources and in included articles' reference lists. Three independent reviewers performed study selection, quality appraisal and data extraction. The risk of bias was assessed with the National Institutes of Health tool. Prevalence was calculated using the random-effects model. Subgroup analysis and meta-regression were used to explore the heterogeneity of results.

RESULTS

The database and grey literature search led to 12 246 results, from which nine studies were included; a further four were selected through citation searching. The total sample comprised 6115 patients with dementia and 84 with MCI. All studies had high risk of bias. The overall estimated pooled prevalence of orofacial pain among dementia participants was 19.0% (95% CI, 11.0%-27.0%; I2 , 97.1%, P < .001). Only one study included MCI participants, among which the prevalence of orofacial pain was 20.5%. Subgroup analysis demonstrated that the different sources of diagnosis might explain the heterogeneity. A higher prevalence of orofacial pain was observed in dementia participants aged over 80 years or living in nursing homes. Meta-regression analysis showed a nonlinear relationship between age and the prevalence of orofacial pain.

CONCLUSIONS

The pooled data from the primary studies revealed that 2 out of 10 patients with dementia have orofacial pain. Further research is needed to clarify the magnitude in individuals with MCI.

Prevention of oral diseases for the older person (Part 1)

Older adults often experience poorer levels of oral health than younger adults, especially if they have become dependent on a third party to support their daily oral care routine. However, the deterioration of oral health does not need to be a part of the ageing process. Most oral diseases are largely preventable with the daily removal of dental plaque that forms on teeth and dentures, using a fluoride toothpaste, eating a healthy diet and reducing any tobacco consumption. The dental team have a duty of care to ensure that older people receive evidence-based oral health preventative advice tailored to the individual, taking into account individual risk factors that can increase with age. This can include the clinical application of topical fluoride and minimally invasive dentistry. Older people at an increased risk of poor oral health include those with cognitive conditions, physical impairments and certain medical conditions. Care home residents face particular barriers to attaining a satisfactory standard of oral care which are discussed herein. Good oral health preventative routines must be established early after the diagnosis of progressive chronic conditions and will help to prevent the need for dental intervention later in life when treatment can be more difficult to tolerate. Inclusion of oral health prevention within health policy and legislation is necessary to improve the oral health for older people living in all health and care settings.

Establishing an empirical conceptual model of oral health in dependent adults: Systematic review

AIM

This qualitative evidence synthesis was performed to establish a conceptual model of oral health in dependent adults that defines the construct of oral health and describes its interrelationships based on dependent adults' and their caregivers' experiences and views.

METHODS

Six bibliographic databases were searched: MEDLINE, Embase, PsycINFO, CINAHL, OATD, and OpenGrey. Citations and reference lists were manually searched. A quality assessment of included studies was conducted independently by two reviewers using the Critical Appraisal Skills Programme (CASP) checklist. The 'best fit' framework synthesis method was applied. Data were coded against an a priori framework and data not captured by this framework were thematically analyzed. To assess the confidence of the findings from this review, the Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) approach was used.

RESULTS

Twenty-seven eligible studies were included from 6126 retrieved studies. Four themes were generated to further understand oral health in dependent adults: oral health status, oral health impact, oral care, and oral health value.

CONCLUSION

This synthesis and conceptual model offer a better understanding of oral health in dependent adults and subsequently provide a starting point to guide establishment of person-centred oral care interventions.

Relationship between oral frailty, health-related quality of life, and survival among long-term care residents

PURPOSE

We evaluated oral frailty (OFr) and its association with health-related quality of life (HRQoL), energy and protein intake, and survival among older long-term care residents.

METHODS

This cross-sectional study with a 3-year follow-up for survival assessed 349 residents in long-term care facilities (73% female, mean age 82 years). We defined OFr with six signs (dry mouth, food residue on oral surfaces, unclear speech, inability to keep mouth open or pain expression during the clinical oral examination, diet pureed/soft) and OFr severity was categorized as Group 1, (mild) = 0-1 signs, Group 2 (moderate) = 2-4 signs, and Group 3 (severe) = 5-6 signs. We measured HRQoL with 15D instrument, and energy and protein intake by a 1- to 2-day food record. Mortality was retrieved from central registers on March 2021.

RESULTS

Of the residents, 15% had 0-1, 67% 2-4 and 18% 5-6 OFr signs. HRQoL decreased linearly from Group 1 to Group 3. OFr correlated with such dimensions of HRQoL as mobility, eating, speech, excretion, usual activities, mental function, and vitality. We found no association between OFr categories and energy and protein intake. Survival decreased linearly from Group 1 to Group 3.

CONCLUSIONS

OFr was common among older long-term care residents and OFr severity predicts poorer outcomes. The six oral signs denoting OFr may be used at the bedside to screen residents at risk for OFr.

Association between oral health and cognitive function among Chinese older adults: the Taizhou imaging study

BACKGROUND

We aimed to investigate the association between oral health and cognitive function in a sample of older adults from a Chinese rural community.

METHODS

The cross-sectional cognitive function of 677 individuals were assessed by Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). A comprehensive profile of the oral health status was evaluated by questionnaire and clinical examination.

RESULTS

Multiple covariates-adjusted regression models demonstrated decayed teeth (DT) and decayed/missing/filled teeth (DMFT) were negatively associated with MoCA score (all p < 0.05). Calculus index (CI) and clinical attachment loss (CAL) were significantly associated with the lower MoCA, short-term memory and executive function score, respectively (all p < 0.05). Additionally, participants with missing teeth unrestored tend to get lower MMSE and MoCA scores (p < 0.05). The results also showed that increased DT and CI were modestly associated with higher odds of cognitive impairment (p < 0.05).

CONCLUSIONS

There is an association between oral health and global cognition. Poor periodontal status was strongly associated with worse global cognition performance, especially in the short-term memory and executive domain for the aging population.

Oral health care services for community-dwelling older people with dementia: A scoping review

OBJECTIVE

To assess whether, and if so, which oral health care services for community-dwelling older people with dementia are available.

BACKGROUND

Oral health in people with dementia is poor compared with people without dementia. Although multiple oral health care interventions have previously been studied for older people living in nursing homes, little is known about interventions or services for community-dwelling older people with dementia.

MATERIALS AND METHODS

A literature search was performed in the databases Pubmed, Embase and CINAHL. The following search terms were used: "Dementia", "Oral health", "Dental health services" and "Older person". The term "dental health services" was intended to be an as broad as possible construct because limited search results were expected.

RESULTS

The search generated 1624 unique references, of which seven studies were eligible for inclusion (four cohort studies, one cross-sectional study, and two qualitative studies). The included studies described two actual oral health care services: a telephone help line on oral health and dementia, and a mobile geriatric dental programme in adult day health centres. A need was found for services and strategies specific to community-dwelling older people with dementia. One identified solution was an intervention with individually tailored daily oral hygiene self-care supported by the informal caregiver. Furthermore, increasing accessibility of oral health care professionals with treatment at other locations than their own practices, better collaboration between health care professionals and preventive oral health care are highly necessary.

CONCLUSION

There is limited evidence on the availability of oral health care services for community-dwelling older people with dementia, while a need was found for oral health care services that focus on good accessibility, oral hygiene self-care, preventive strategies and collaboration among health care professionals.

Effect of a single application of silver diamine fluoride on root caries after 12 months in institutionalised older adults-A randomised clinical trial

OBJECTIVE

Silver diamine fluoride (SDF) has been shown to be highly effective against caries, in particular for arresting root surface caries and for dentine caries in primary teeth. SDF may complement fluoride varnish routines for treatment of root caries in nursing home residents. The aim of this randomised, single-blinded, placebo-controlled trial was to evaluate the additive effect of a single annual application of SDF for prevention and treatment of incipient root caries in older adult nursing home residents.

METHOD

Four hundred older adult nursing home residents (≥70 years old) with at least one exposed root surface (on teeth 15, 14, 13, 23, 24, or 25) were identified during routine dental examination visits in the domiciliary dental care setting. Eligible patients, who were able to understand the implication of consenting to the study, were invited to participate. Their cleaned root surfaces were randomly allocated to treatment with SDF (Advantage Arrest Silver Diamine Fluoride 38%, Advantage Arrest, LLC, Redmond, OR 97756, USA, Lot 16 152) or with placebo (tap water), each for 1 minute.

RESULTS

Of the 400 eligible individuals, 42 declined to participate and two forms were destroyed. The remaining 356 participants (89.0%; mean age 87.7 years) were randomly allocated, with 174 going to the SDF group and 182 to the placebo group. At 1 year, 273 participants (76.7%) were available for assessment: 135 in the SDF group and 138 in the placebo group. By that time, 109 individuals (39.9%) demonstrated root caries progression or regression. Among those 118 (16.7%) of the 708 included root surfaces had developed caries There were no statistically significant differences in the primary outcome related to treatment with SDF or placebo, at either patient or root surface level.

CONCLUSION

Based on the finding of this clinical trial, it is concluded that a single SDF application to complement a risk-based preventive programme including fluoride varnish applications did not have a statistically significant additional preventive effect on root caries development in a group of older adult nursing home residents with limited caries activity and cognitive capacity to cooperate in oral care activities.

No genetic causal association between dental caries and Alzheimer's disease: a bidirectional two-sample Mendelian randomization analysis

Background

An increasing number of observational studies have suggested an association between dental caries and Alzheimer's disease (AD). The association between dental caries and Alzheimer's disease may be mediated by confounders or reverse causality. In this study, we conducted bidirectional two-sample Mendelian randomization (MR) to estimate the bidirectional causality between dental caries and AD.

Materials and Methods

Genome-wide association study (GWAS) summary statistics of dental caries were extracted from a published meta-analysis which included a total of 487,823 participants. GWAS datasets of AD and AD onset age were obtained from the FinnGen bank. A bidirectional two-sample analysis was performed to explore the causality between dental caries and AD.

Results

For the dental caries-AD causality estimation, there was no significant association between dental caries and AD, neither with the AD GWASs from the FinnGen database (OR: 1.041, p = 0.874) nor with those from the International Genomics of Alzheimer's Project (OR: 1.162, p = 0.409). In addition, the genetic susceptibility to dental caries was not related to the onset age of AD. No causality existed between dental caries and early-onset AD (OR: 0.515, p = 0.302) or late-onset AD (OR: 1.329, p = 0.347). For the AD-dental caries relationship, no causality was detected by the IVW method (OR: 1.000, p = 0.717). Findings from other MR methods were consistent. The pleiotropy test and sensitivity analysis confirmed the validity of these MR results.

Conclusions

In this bidirectional MR study, robust evidence to support a bidirectional causal effect between dental caries and AD from the GWAS results within large-scale European-descent populations was absent. Having dental caries would not alter the onset age of AD.

The interaction between the nervous system and the stomatognathic system: from development to diseases

The crosstalk between the nerve and stomatognathic systems plays a more important role in organismal health than previously appreciated with the presence of emerging concept of the "brain-oral axis". A deeper understanding of the intricate interaction between the nervous system and the stomatognathic system is warranted, considering their significant developmental homology and anatomical proximity, and the more complex innervation of the jawbone compared to other skeletons. In this review, we provide an in-depth look at studies concerning neurodevelopment, craniofacial development, and congenital anomalies that occur when the two systems develop abnormally. It summarizes the cross-regulation between nerves and jawbones and the effects of various states of the jawbone on intrabony nerve distribution. Diseases closely related to both the nervous system and the stomatognathic system are divided into craniofacial diseases caused by neurological illnesses, and neurological diseases caused by an aberrant stomatognathic system. The two-way relationships between common diseases, such as periodontitis and neurodegenerative disorders, and depression and oral diseases were also discussed. This review provides valuable insights into novel strategies for neuro-skeletal tissue engineering and early prevention and treatment of orofacial and neurological diseases.

Clinical and Subjective Oral Health Status of Care Home Residents in Europe: A Systematic Review

OBJECTIVE

Several studies demonstrated the poor oral health of care home residents in Europe but there is no systematic overview of the relevant literature. The objective of this study was to systematically review the evidence on the clinical and subjective oral health outcomes of care home residents in Europe.

DESIGN

The study design is a systematic review.

METHODS AND PARTICIPANTS

All included publications presented data on clinical and/or subjective oral health outcomes in care home residents in Europe with no restrictions for language or study design. MEDLINE, Embase, and CINAHL were searched, including publications from January 2010 onward. Data extraction and quality assessment (Qualsyst tool) was performed by 2 researchers independently. Findings were synthesized narratively, lack in data homogeneity restricted the relevance of a meta-analysis.

RESULTS

Eighty-three papers from 18 countries were included in the systematic review, with a sample size ranging from 39 to 92,827 participants. Their mean age was older than 80 years. The residents had few natural teeth, with fewer than a third a functional natural dentition. Removable dentures were present in half to 80% of residents. A high prevalence of dental caries was reported. Oral hygiene was insufficient, for both natural teeth and removable dentures. Few residents had a healthy periodontium. Clinical treatment needs were found in most residents. Perceived treatment needs were high with at least one-third of care home residents reporting a need for care due to poor oral health. A fifth to half of the residents reported negative impacts of their oral condition on their everyday lives.

CONCLUSION AND IMPLICATIONS

This systematic review clearly highlights the poor oral health and high burden of oral conditions among care home residents across Europe, irrespective of country or health care system. There is need for substantial policy actions to improve oral health in care homes.

Interaction of Systemic Morbidity and Oral Health in Ambulatory Patients in Need of Home Care (InSEMaP): an observational study at the sector boundary between dental and general practice care in Germany

INTRODUCTION

Older people in need of home care are at risk of declining oral health as their visits to dentists are becoming less frequent due to restricted mobility. There is increasing evidence that poor oral health and systemic diseases are closely associated, for example, in cardiological, metabolic or neurodegenerative conditions. Thus, Interaction of Systemic Morbidity and Oral Health in Ambulatory Patients in Need of Home Care (InSEMaP) is investigating the need, provision and utilisation of oral healthcare, systemic morbidity and clinical status of the oral cavity in older people.

METHODS AND ANALYSIS

InSEMaP consists of four subprojects (SP), all involving the target population of older people in need of home care. In SP1 part a, a sample is surveyed using a self-report questionnaire. In SP1 part b, stakeholders (general practitioners, dentists, medical assistants, family and professional caregivers) are interviewed regarding barriers and facilitators using focus groups and personal interviews. In SP2, a retrospective cohort study, health insurance claims data are examined to investigate the utilisation of oral healthcare, its association with systemic morbidity and healthcare costs. In SP3, a clinical observational study will assess the oral health of participants by a dentist's visit at home. SP4 synthesises the results of SP1, SP2 and SP3 to develop integrated clinical pathways, identifying strategies to uphold oral healthcare in older people. In assessing and evaluating the process of oral healthcare, and its associated systemic morbidity, InSEMaP aims to improve general healthcare across the sector boundary of dental and general practitioner care.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Institutional Review Board of the Hamburg Medical Chamber (approval number: 2021-100715-BO-ff). The results of this study will be disseminated through conference presentations and publications in peer-reviewed journals. An expert advisory board to support the InSEMaP study group will be established.

TRIAL REGISTRATION NUMBER

Use of a powered toothbrush to improve oral health in individuals with mild cognitive impairment

OBJECTIVES

The aim of the study is to investigate whether the use of a powered toothbrush could maintain oral health by reducing the dental plaque (PI), bleeding on probing (BOP), and periodontal pocket depth (PPD) ≥4 mm in a group of individuals with MCI and also if changes in oral health affect various aspects of quality of life.

BACKGROUND

People with cognitive impairment tend to have poor oral hygiene and poorer Quality of life. In the present study, the participants were asked to use a powered toothbrush for at least 2 min morning and evening and no restrictions were given against the use of other oral care products. The participant survey conducted at each examination demonstrated that 61.2% of participants at baseline claimed to have experience of using a powered toothbrush, 95.4% at 6 months and 95% after 12 months. At the same time, the use of manual toothbrushes dropped from 73.3% to 44.7% from baseline to the 12-month check-up. This shows that several participants continue to use the manual toothbrush in parallel with the powered toothbrush, but that there is a shift towards increased use of the powered toothbrush. Removal of dental biofilm is essential for maintaining good oral health. We investigated whether using a powered toothbrush reduces the presence of dental plaque, bleeding on probing and periodontal pockets ≥4 mm in a group of older individuals with mild cognitive impairment.

MATERIALS AND METHODS

Two hundred and thirteen individuals with the mean age of 75.3 years living without official home care and with a Mini-Mental State Examination (MMSE) score between 20 and 28 and a history of memory problems in the previous six months were recruited from the Swedish site of a multicenter project, Support Monitoring And Reminder Technology for Mild Dementia (SMART4MD) and screened for the study. The individuals received a powered toothbrush and thorough instructions on how to use it. Clinical oral examinations and MMSE tests were conducted at baseline, 6 and 12 months.

RESULTS

One hundred seventy participants, 36.5% women and 63.5% men, completed a 12-month follow-up. The use of a powered toothbrush resulted, for the entire group, in a significant decrease in plaque index from 41% at baseline to 31.5% after 12 months (P < .000). Within the same time frame, the values for bleeding on probing changed from 15.1% to 9.9% (P < .000) and the percentage of probing pocket depths ≥4 mm from 11.5% to 8.2% (P < .004). The observed improvements in the Oral Health Impact Profile 14 correlate with the clinical improvements of oral health.

CONCLUSION

The use of a powered toothbrush was associated with a reduction of PI, BOP and PPD over 12 months even among individuals with low or declining MMSE score. An adequately used powered toothbrush maintain factors that affect oral health and oral health-related Quality of Life in people with mild cognitive impairment.

Unlocking Modifiable Risk Factors for Alzheimer's Disease: Does the Oral Microbiome Hold Some of the Keys?

Advancing age is recognized as the primary risk factor for Alzheimer's disease (AD); however approximately one third of dementia cases are attributable to modifiable risk factors such as hypertension, diabetes, smoking, and obesity. Recent research also implicates oral health and the oral microbiome in AD risk and pathophysiology. The oral microbiome contributes to the cerebrovascular and neurodegenerative pathology of AD via the inflammatory, vascular, neurotoxic, and oxidative stress pathways of known modifiable risk factors. This review proposes a conceptual framework that integrates the emerging evidence regarding the oral microbiome with established modifiable risk factors. There are numerous mechanisms by which the oral microbiome may interact with AD pathophysiology. Microbiota have immunomodulatory functions, including the activation of systemic pro-inflammatory cytokines. This inflammation can affect the integrity of the blood-brain barrier, which in turn modulates translocation of bacteria and their metabolites to brain parenchyma. Amyloid-β is an antimicrobial peptide, a feature which may in part explain its accumulation. There are microbial interactions with cardiovascular health, glucose tolerance, physical activity, and sleep, suggesting that these modifiable lifestyle risk factors of dementia may have microbial contributors. There is mounting evidence to suggest the relevance of oral health practices and the microbiome to AD. The conceptual framework presented here additionally demonstrates the potential for the oral microbiome to comprise a mechanistic intermediary between some lifestyle risk factors and AD pathophysiology. Future clinical studies may identify specific oral microbial targets and the optimum oral health practices to reduce dementia risk.

Oral health-related multiple outcomes of holistic health in elderly individuals: An umbrella review of systematic reviews and meta-analyses

Background and aims

Along with an aging population, exploring the impact of oral health on holistic health and determining exact outcomes in elderly individuals are important in both scientific research and clinical practice. Significant increase in the number of systematic reviews shows that oral health can directly or indirectly affect the overall health of elderly people physically, mentally and socially. To systematically collate, appraise, and synthesize the current evidence, we carried out an umbrella review of the impacts of oral health on holistic health in elderly individuals.

Methods

A systematic reviews and meta-analyses search was performed in the major databases PubMed, MEDLINE, Web of Science and the Cochrane Library from inception to February 1, 2022, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The JBI (Joanna Briggs Institute) Critical Appraisal Checklist for Systematic Reviews and Research Syntheses was referred to assess methodological quality, and the GRADE (Grading of Recommendations, assessment, Development, and Evaluation working group classification) was used to assess the quality of evidence for each outcome included in the umbrella review.

Results

Out of 1,067 records, a total of 35 systematic reviews were included. Respiratory diseases, malnutrition, age-related oral changes, frailty, cognitive impairment, depression and poor quality of life were identified as seven key outcomes that affect the physical, mental and social health of elderly individuals. Meanwhile, three intervention measures of oral health were summarized as (i) more rigorous and universal scales, (ii) dental cleaning and denture installation, and (iii) improving self-awareness regarding oral care.

Conclusions

Evidence showed that oral health can significantly affect holistic health, and the diverse oral diseases directly lead to multiple health outcomes in elderly individuals. Clear high-quality evidence revealed that oral health is strongly associated with seven health outcomes covering physical, mental, and social levels, which directly corresponds to holistic health, and impacts the quality of life of elderly individuals. Such the results remind the importance of oral care in public health, and further studies need to be conducted to verity more specific association between oral health and other chronic diseases.

Interventions to Improve the Oral Hygiene of Individuals with Alzheimer's Disease: A Systematic Review

This systematic review evaluates published evidence on oral hygiene interventions conducted in Alzheimer’s disease (AD) patients. PubMed, Embase, Cochrane Library, CINAHL, Dentistry & Oral Sciences Source, and Web of Science were searched for articles published up to 19 April 2021. The main outcomes of interest were the Plaque index score (PI), oral health knowledge of participants or their caregivers, and behaviors and attitudes towards oral hygiene. Study quality was assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies of the National Institutes of Health. The study was conducted under PROSPERO registration code CRD42021247733. Two studies met the inclusion criteria. One was a pre-post study conducted in Brazil, and the other was a prospective cohort study carried out in China. The sample sizes of these studies were 29 and 168, respectively. Both studies were carried out in institutionalized patients and presented a significant loss to follow-up. The PI and gingival index scores both improved after the application of the respective interventions, yet the differing methodologies used precluded further comparisons. The studies were deemed to be of good and regular quality, respectively. Despite the need for more comprehensive interventions to ensure a better oral health status and a higher quality of life for AD patients, an alarming lack of studies have been conducted in this population.

Understanding Pain and Agitation Through System Analysis Algorithms in People With Dementia. A Novel Explorative Approach by the DIGI.PAIN Study

Background

Many people with dementia (PwD) live and die with undiagnosed and untreated pain and are no longer able to report their suffering. Several pain assessment tools have been developed, tested, and implemented in clinical practice, but nursing home patients are reported to be still in pain. Clinicians and research groups worldwide are seeking novel approaches to encode the prediction, prevalence, and associations to pain in PwD.

Participants

The data in this analysis are acquired from the COSMOS study, a cluster-randomized controlled trial (2014 to 2015), aimed to improve the quality of life in nursing home patients (N = 723) through the implementation of a multicomponent intervention. We utilize baseline data of PwD (N = 219) with complete datasets of pain and agitation.

Method

Systems analysis explores the relationship between pain and agitation using the Mobilization-Observation-Behavior-Intensity-Dementia (MOBID-2) Pain Scale, Cohen-Mansfield Agitation Inventory (CMAI), and Neuropsychiatric Inventory-Nursing Home version (NPI-NH). For each patient, the individualized continuous time trajectory, and rates of change of pain and agitation are estimated. We determine the relationship between these rates by analyzing them across the entire group.

Results

We found that the new analysis method can generate individualized estimations for pain and agitation evolution for PwD, as well as their relationship. For 189 of 219 PwD, results show that whenever pain increases or decreases, agitation does too, with the same rate. The method also identifies PwD for whom pain or agitation remains constant while the other varies over time, and patients for whom agitation and pain do not change together. The algorithm is scalable to other variables and compatible with wearable devices and digital sensors.

Conclusion

We presented a new approach to clinical data analysis using systems concepts and algorithms. We found that it is possible to quantify and visualize relationships between variables with a precision only dependent on the precision of measurements. This method should be further validated, but incipient results show great potential, especially for wearable-generated continuous data.

Impact of an Oral Hygiene Intervention in People with and without Dementia on Oral Health Parameters-Results from the Oral Health, Bite Force, and Dementia (OrBiD) Pilot Study

This study aimed to assess the influence of an oral hygiene intervention on oral health, depending on the degree of dementia. A clinical evaluation of oral health parameters (index of decayed, missing, and filled teeth (DMFT-index), periodontal screening index (PSI), oral hygiene index (OHI), and bleeding on probing (BOP)) was performed in 120 subjects assigned to five groups, based on the mini mental state examination (MMSE) at baseline and after 12 months. Each MMSE group (no dementia (noDem, MMSE 28–30), mild cognitive impairment (mCI, MMSE 25–27), mild dementia (mDem, MMSE 18–24), moderate dementia (modDem, MMSE 10–17), and severe dementia (sDem, MMSE ≤ 9)) was split into control (no intervention) and experimental groups (intervention on oral hygiene: increased frequency, daily usage of high-fluoride toothpaste). In total, 99 out of 120 subjects were included in the analysis. The dropout rate was high in subjects with modDem and sDem due to death. In subjects with noDem, mCI, and mDem, no changes in the DMFT were found, but improvements in the OHI, BOP, and PSI were observed. Subjects with modDem or sDem demonstrated a deterioration in DMFT; however, in these patients, OHI improved in all control and experimental groups, BOP improved in the experimental group only, and PSI did not improve at all. The scope of improving oral health parameters by increasing the recall frequency and by continuously using high fluoride toothpaste is at its limits in people with severe dementia. Multidimensional approaches should be sought to improve the oral health of vulnerable older patients.

A possible indicator for removal of a large foreign body from the esophagus via a cervical approach: a case report with literature review

Foreign body intake in adults is more common among people with mental illness. Edentulous adults are at increased risk for foreign body ingestion, including of dentures. We experienced a patient who aspirated a large denture that we removed via a cervical surgical approach. A 72-year-old woman presented complaining of chest discomfort. Her medical history revealed that she suffered from schizophrenia and deafness. She had previously visited another hospital for possible loss of her denture. Chest discomfort and pain began the next day. Computed tomography showed the accidentally swallowed denture in her esophagus. Upper gastroendoscopy was attempted to remove the denture via endoscopic forceps, but it was too large to be removed and was strongly stuck. As it was difficult to perform open right thoracotomy due to left pneumonia and there was no perforation or mediastinitis, we decided to remove the denture via a left neck skin incision under general anesthesia. The denture was located in a gap between the aortic arch and vertebral body. The denture was grasped with pean forceps and extracted. The patient was discharged from hospital 18 days postoperatively. This case suggests how high a foreign body in the esophagus can be reached from a cervical incision.

Orofacial pain among Chinese older adults in the last year of life

OBJECTIVE

To examine the prevalence of orofacial pain and associated factors in Chinese older adults at the end of life.

METHODS

This cross-sectional study included 1646 participants (65 years or older) in their last year of life from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We used the 6-month prevalence questions to measure two specific orofacial pain symptoms: toothache, and jaw or facial pain. Logistic regression analyses were used to examine factors, such as socioeconomic status, health behaviours and chronic diseases, that were associated with these two orofacial pain symptoms in the last year of life.

RESULTS

The 6-month prevalence estimates for toothache and jaw pain or facial pain for older adults in the last year of life were 14.1% and 4.5% respectively. Higher socioeconomic status was associated with lower odds of toothache and jaw pain or facial pain. Smoking was associated with high odds of toothache. Participants who brushed their teeth at least once a day were more likely to have toothache and jaw or facial pain than those who did not. Having any chronic conditions was associated with higher odds of toothache and jaw or facial pain. Older adults who had at least one tooth were more likely to have jaw or facial pain than those without any teeth.

CONCLUSION

A considerable proportion of Chinese older adults in their last year of life reported toothache and/or jaw pain or facial pain. These findings suggest that appropriate measures need to be taken to address the oral health needs in these vulnerable individuals, especially those of low socioeconomic status and chronic conditions.

Relationship between Fried's frailty phenotype and oral frailty in long-term care residents

BACKGROUND

oral frailty (OFr) may be called a syndrome lacking a consensus on its definition.

OBJECTIVE

the aim was to prove the relationship between OFr to the phenotype of frailty, general health and nutrition in long-term care.

DESIGN

the FINnish ORAL Health Study in Long-Term Care study is a cross-sectional clinical research comprising findings on oral and general health and nutrition.

SETTING

participants were divided into groups according to the number of OFr signs: Group 1 (0-1 sign), Group 2 (2-4 signs) and Group 3 (5-6 signs).

SUBJECTS

the study includes data on 349 older residents of long-term care facilities in Helsinki, Finland.

METHODS

frailty status was defined according to Fried's frailty phenotype. OFr was evaluated with six signs: dry mouth, diet of pureed or soft food, residue of food on oral surfaces, unclear speech, inability to keep mouth open during the clinical oral examination and pain expression during the examination.

RESULTS

a significant linear relationship across the OFr groups with Fried's frailty phenotype was found (P for linearity = 0.008, adjusted by gender and age). A linear trend existed between OFr groups and general health; prevalence of dementia and malnutrition increased from Group 1 to Group 3. The need for help with eating and oral hygiene procedures increased from Group 1 to Group 3. Moreover, OFr had a linear relationship with chewing and swallowing difficulties.

CONCLUSIONS

OFr is related to Fried's frailty phenotype, general health, nutrition and need for help with daily activities.

Associations between dental caries and systemic diseases: a scoping review

BACKGROUND

The objective of this study was to evaluate and present evidence from animal and human clinical studies on associations between dental caries and systemic diseases, and to suggest potential mechanisms that might explain such associations.

METHODS

An electronic search was conducted of PubMed, Embase and Cochrane Central Register of Controlled Trials for articles published from 2010 to 2020 in the English language. From the initial search, 404 full-text studies were assessed for eligibility. After excluding studies for technical and study limitations, a total of 67 studies were included in the summary tables and additional studies were included in the review to support evidence.

RESULTS

Few systemic disease and conditions were found to be clinically meaningfully associated with caries experience. Best evidence from human and animal studies described association between metabolic diseases and dental caries. Several interesting animal studies were noted that could generate clinical hypotheses and further investigations in rodent models for cardiovascular injury and hyperglycemia. Inadequate data was found to suggest any modifications to current clinical practice or prevention guidelines.

CONCLUSIONS

Limited clinical evidence was found connecting several systemic diseases and dental caries. Inadequate data was found to suggest any modifications to current clinical practice or prevention guidelines.

CLINICAL SIGNIFICANCE

Understanding of associations between dental caries and systemic diseases play a crucial role in the treatment planning and education of the dental patient.

Oral Health Assessment Tool (OHAT) deputized to informal caregivers: Go or no go?

OBJECTIVE

Investigating the usability of the Dutch version of the Oral Health Assessment Tool (OHAT-NL) with informal caregivers of community-dwelling older people with suspected dementia, without specific training.

MATERIALS AND METHODS

In accordance with guidelines for establishing the cultural equivalency of instruments, the OHAT was translated into Dutch. Fifteen informal caregivers of community-dwelling older people with suspected dementia and, as a reference standard, a dentist assessed the oral health of the older people using the OHAT-NL. The caregivers' scores were compared with the dentist's scores. The usability of the OHAT-NL was rated on a 10-point scale (0 = incomprehensible, and 10 = very user friendly) and investigated further through short structured interviews.

RESULTS

There were differences between the dentist's and caregivers' assessments of the individual categories of the OHAT-NL. The specificity of the need to visit an oral health care professional was 100.0%, while the sensitivity was 78.6%. The informal caregivers concluded that the tool made them more aware of different aspects of oral health. The tool was rated with a mean score of 7.7 (SD 1.7).

CONCLUSION

The OHAT-NL could be a useful tool for informal caregivers without specific training to indicate whether the person they care for should visit an oral health care professional.

When should root remnants and unrestorable broken teeth be extracted in frail older adults?

BACKGROUND

Many frail older adults have an unhealthy dentition; unrestorable broken teeth and root remnants with open root canals, commonly accompanied by periapical and periodontal inflammation, are often seen. Improving oral health in the growing group of frail older adults with remaining teeth is a considerable challenge for dental care professionals. Dentists are often uncertain how to deal with root remnants and unrestorable broken teeth in frail older adults.

METHODS

The authors aim was to provide recommendations to dentists to help in their clinical decision making about the extraction or retention of roots remnants and broken teeth in frail older adults.

CONCLUSIONS

Decisions about the extraction or retention of root remnants should made on the basis of preventing pain and oral discomfort, preventing severe inflammation, and preventing additional decline in oral health. Both root-related and patient-related factors are considered.

PRACTICAL IMPLICATIONS

Decision-making trees can help dentists decide whether to extract root remnants and unrestorable broken teeth in frail older adults.

Chewing function and related parameters as a function of the degree of dementia: Is there a link between the brain and the mouth?

Background

To date, no study has investigated the association between chewing function and related parameters as a function of the degree of dementia using a finer subdivision of the values of the Mini‐Mental State Examination (MMSE).

Objective

This study aimed to investigate the differences in chewing function and related parameters as a function of the degree of dementia.

Methods

An analysis of cross‐sectional data obtained from the OrBiD (Oral Health, Bite Force, and Dementia) pilot study was performed. The participants were stratified into five groups based on the outcomes of the MMSE (no dementia, MMSE 28–30; mild cognitive impairment, MMSE 25–27; mild dementia, MMSE 18–24; moderate dementia, MMSE 10–17; severe dementia, MMSE <10). The chewing efficiency, maximum occlusal force and related parameters (number of supporting zones, number of teeth, Eichner index, tooth/denture status, denture quality, and dental treatment needs) were recorded.

Results

The MMSE groups showed significantly different chewing efficiencies (p = .003, Jonckheere‐Terpstra test) and maximum occlusal forces (p = .003, Jonckheere‐Terpstra test), but the number of supporting zones (p = .055, chi‐square test) and the number of natural teeth (p = .126, chi‐square test) were not different. The Eichner index, tooth/denture status, denture quality and dental treatment need showed no significant associations with the degree of dementia.

Conclusion

An improvement in the usability of the measurement methods for assessing chewing function in people with dementia is needed. Research involving people with dementia is necessary because the nutritional situation often deteriorates rapidly within a multifactorial system, which includes chewing ability and oral health.

Family perceptions of mouth care for assisted living residents with dementia: Implications for care

Mouth care is an important component of care for persons with dementia in assisted living (AL). However, there is little information about family member knowledge, beliefs, and experiences with resident oral health. Family perceptions and involvement in care may impact oral and systemic health for AL residents. Therefore, semi-structured interviews to assess these domains were conducted with 23 adult family members of AL residents with dementia, from 9 AL communities. Thematic analysis found that families identified (1) the centrality of oral health to well-being; (2) organizational influences on mouth care; (3) mouth care in the context of dementia; and (4) collaboration to facilitate mouth care. Family perspectives can provide useful guidance for collaborative interventions that support oral health and mouth care in AL.

The effect of multimodal comprehensive care methodology training on oral health care professionals' empathy for patients with dementia

BACKGROUND

The prevalence of oral diseases in people with dementia has increased, and patients with dementia have worse oral health than people without dementia. However, in the provision of oral care, these patients often exhibit care-resistant behaviours. Empathy is important for health care professionals who provide dental care for people with dementia. A study was conducted to assess whether a multimodal comprehensive care methodology training programme, Humanitude™, was associated with an improvement in empathy for people with dementia among oral health care professionals.

METHODS

This research was a pre-post prospective study. A total of 45 dentists and dental hygienists participated in a 7-h multimodal comprehensive care methodology training programme. Participants' empathy for their patients was evaluated with the Jefferson Scale of Physician Empathy-Health Professionals Version (JSPE-HP) before the training and 1 month after the training (primary outcome). Each participant listed 3 patients with poor oral health due to the refusal of usual oral care or dental treatment from his or her clinical practice. The oral health of the 3 care-resistant patients listed by each participant was evaluated by the Oral Health Assessment Tool (OHAT) before the training and 1 month after the training (secondary outcome).

RESULTS

The post-training response rate was 87% (21 dentists and 18 dental hygienists). From pre-training to post-training, the multimodal comprehensive care methodology training significantly increased the mean empathy score (from 113.97 to 122.95, P < 0.05, effect size = 0.9). Regardless of gender, profession and years of clinical experience, all post-training subgroup scores were higher than the pre-training subgroup scores. The tongue, natural teeth, and oral hygiene scores of patients with dementia who resisted usual oral care or dental treatment, as assessed by the OHAT, were significantly improved compared with those before the training.

CONCLUSIONS

The multimodal comprehensive care methodology training was associated with an improvement in oral health professionals' empathy for patients with dementia. These findings suggest that randomized controlled trials with large sample sizes will be needed.

The Association between Age-Related Changes in Oral Neuromechanics and Alzheimer's Disease

The global population of 80 years and older is predicted to reach 437 million by 2050. As overall brain structure and function progressively degrades, older and younger adults show differences in sensorimotor performance and brain activity in the sensorimotor regions. Oral sensorimotor functions are an important area of focus in natural aging and Alzheimer’s Disease (AD) because oral health issues are commonly found in both elderly and AD populations. While human behavioral studies on changes in oral sensorimotor functions abound, very little is known about their neuronal correlates in normal and pathological aging.

Oral health in patients with dementia: A meta-analysis of comparative and observational studies

OBJECTIVE

Poor oral health is common in dementia, but findings of epidemiological studies have been inconsistent. This meta-analysis examined oral health in patients with dementia diagnosed according to standardized diagnostic criteria.

METHODS

Six international databases (PubMed, EMBASE, PsycINFO, Medline, Cochrane Library, and Web of Science) were searched from their commencement date until 8 November 2018. Oral health was measured by the Remaining Teeth (RT) and Decayed, Missing, and Filled Teeth (DMFT) Index. The mean differences (MD) and 95% confidence intervals (CI) of DMFT Index total and component scores were calculated using a random-effect model.

RESULTS

Twenty-four studies were included for analyses. The pooled DMFT Index was 23.48 (95% CI: 22.34, 24.62), while the pooled score for each component was 2.38 (95% CI: 1.56, 3.20) in decayed teeth (DT), 18.39 (95% CI: 15.92, 20.87) in missing teeth (MT), 2.29 (95% CI: 0.62, 3.95) in filled teeth (FT), and 11.59 (95% CI: 9.14, 14.05) in RT. Compared to controls, people with dementia had significantly a higher DMFT Index total score (MD = 3.80, 95% CI: 2.21, 5.39, p < 0.00,001), and significantly lower number of RT (MD = -3.15, 95% CI: -4.23, -2.06, p < 0.00,001). Subgroup analyses revealed that higher DMFT Index score was significantly associated with year of survey (>2010), study design (case-control study), percentage of females (≤54.3), and the Mini Mental State Examination score (≤18.2). Higher MT score was significantly associated with study design (cross-sectional study), and lower FT score was significantly associated with year of survey (>2010).

CONCLUSIONS

Oral health was significantly poorer in people with dementia compared with controls. Regular screening and effective treatment should be implemented for this population.

Intranasal midazolam for the sedation of geriatric patients with care-resistant behaviour during essential dental treatment: An observational study

OBJECTIVES

To describe the efficacy and safety of intranasal midazolam for sedation during essential dental treatment of geriatric patients with major neurocognitive disorder (MND) and care-resistant behaviour (CRB).

BACKGROUND

Dental treatment is often impossible in geriatric MND patients with CRB. Intranasal midazolam may provide a non-invasive sedation method, but there is currently no information on its use in geriatric patients.

METHODS

In this observational study, we included geriatric patients with severe MND and CRB needing urgent dental treatment. Each patient received 5 mg midazolam intranasally. Agitation/sedation levels, heart rate, respiration rate and oxygen saturation were recorded at 5-minute intervals.

RESULTS

Thirty two patients were included. Mean age was 84 (±7) years. Mean (SD) time to treatment start was 13 (±5) minutes, and mean time to maximum sedation 17 (±11) minutes. Sedation was sufficient to enable dental treatment to be completed in 31 (97%) patients. Anxiolysis/light sedation occurred in 16 (50%) patients, and moderate to deep sedation occurred in 16 (50%) patients. No patients suffered from apnoea, although 3 patients required a chin-lift manoeuvre. Hypoxaemia occurred in 1 of these patients and in 2 other patients without airway obstruction. All patients recovered uneventfully. In a regression model, age, weight and other sedative medication use were found not to be associated with maximum sedation depth.

CONCLUSIONS

Of 5 mg intranasal midazolam facilitates treatment of geriatric patients with MND in the comfort of their own environment. More information is needed to guide titration to balance the desired sedation level and patient safety.

Management of Dysphagia in Nursing Homes: A National Survey

The management of dysphagia may differ by country and clinical setting. The purpose of this study was to describe the management and care pathways for elderly people with dysphagia in nursing homes across Norway using an online survey. A national survey was developed that consisted of 23 questions covering various areas related to dysphagia care in nursing homes: background information of respondents, nursing homes, and residents and staff; screening and assessment of dysphagia including use of specialist consultation; management, practice patterns, and interventions targeting residents with dysphagia; training of staff; and perceived quality of current clinical practices in their nursing home. A total of 121 respondents completed the online survey, resulting in an overall response rate of 23.2%. Substantial discrepancies in dysphagia management were identified between nursing homes. In approximately 75% of nursing homes, residents were not routinely screened or assessed for swallowing problems. Although nursing homes used a broad range of strategies and routines for people with eating and swallowing difficulties, bolus modification seemed standard practice. Oral hygiene strategies were lacking in over 80% of nursing homes, and almost 50% did not have access to external experts, including speech therapists. Although nursing home staff rated the overall quality of care for people with eating and swallowing problems as high, their rating seemed mainly based on care for malnutrition and not directly aimed at dysphagia. The survey identified an evident need for training and upskilling staff in Norwegian nursing homes and raising awareness of the serious consequences and comorbidities that can result from dysphagia.

Cognitive Performance and Its Associations with Dental Caries: Results from the Dental, Oral, Medical Epidemiological (DOME) Records-Based Nationwide Study

Relatively few studies have analyzed the association between cognitive performance and dental status. This study aimed to analyze the association between cognitive performance and dental caries. Included were data from the dental, oral, medical epidemiological (DOME) study; cross-sectional records-based research, which integrated large socio-demographic, medical, and dental databases of a nationally representative sample of young to middle-aged military personnel (N = 131,927, mean age: 21.8 ± 5.9 years, age range: 18-50). The cognitive function of draftees is routinely measured at age 17 years using a battery of psychometric tests termed general intelligence score (GIS). The mean number of decayed teeth exhibited a gradient trend from the lowest (3.14 ± 3.58) to the highest GIS category (1.45 ± 2.19) (odds ratio (OR) lowest versus highest = 5.36 (5.06-5.68), p < 0.001). A similar trend was noted for the other dental parameters. The associations between GIS and decayed teeth persisted even after adjusting for socio-demographic parameters and health-related habits. The adjustments attenuated the OR but did not eliminate it (OR lowest versus highest = 3.75 (3.38-4.16)). The study demonstrates an association between cognitive performance and caries, independent of the socio-demographic and health-related habits that were analyzed. Better allocation of resources is recommended, focusing on populations with impaired cognitive performance in need of dental care.

Oral function and its association with nutrition and quality of life in nursing home residents with and without dementia: A cross-sectional study

Background

Oral health problems increase with age, and are common in nursing home residents, especially in those with dementia. These problems can lead to tooth loss, diminished oral function and malnutrition.

Objectives

To compare oral function, nutritional status and quality of life (QoL) between residents with and without dementia, and to examine associations between these variables.

Methods

Cross‐sectional study conducted in four UK nursing homes. Residents aged 65 + with and without dementia were included. Information was collected on demographics, dental status, quality of swallowing and chewing, xerostomia and orofacial pain. During oral examination, information was collected on number of teeth and occlusal units (OU), and functional categories (eg, OU combined with dentures). Multiple linear regression was used for statistical analysis.

Results

Of 84 residents with and 27 without dementia participated. Residents with dementia had significantly fewer teeth (Dementia median (IQR) = 14 (6‐21), vs No dementia 22 (12.75‐24.25); P = .021), fewer OU (Dementia median (IQR) = 0 (0‐3), vs No dementia 4 (0‐7); P = .001) and poorer functional categories (Z = −3.283; P = .001), and nutritional status was significantly poorer than those without (Dementia Mean (SD) = 8.3 (2.7), vs No dementia 10.4 (2.0); P = .002). In the regression model, quality of chewing (Coef (95% CI) = −1.27 (−2.22, −0.31); P = .010) was significantly correlated with nutritional status.

Conclusion

Oral function and nutritional status of residents with dementia was poorer than those without. Almost half of all residents had insufficient oral function, which was negatively associated with QoL and nutritional status.

Which factors influence the oral health of nursing-home residents with cognitive and motor impairments?

Background

There is limited information available about the oral and denture hygiene and oral health of nursing-home residents with cognitive and motor impairments.

Aims

The purpose of this study was to identify factors influencing the oral and denture hygiene and oral health of nursing-home residents with cognitive and motor impairments.

Methods

The study was performed in nine nursing-homes in Germany. Sociodemographic and general data were collected for all participants (n = 150). The Clinical Dementia Rating (CDR) was used to identify the presence of dementia, and the Apraxia Screening Test (AST) was used to identify motor impairment. A comprehensive dental examination was also performed. This included the documentation of dental and denture status and the number of decayed, missing and filled teeth (DMFT). In addition, dental and denture hygiene were assessed using the Plaque Index (PI) and the Denture Hygiene Index (DHI). Univariate and multivariate regression models were used to analyse possible factors affecting the dependent target variables.

Results

In multivariate regression analysis, the factors that most strongly influenced greater PI were a lower number of medications taken (p = 0.018), poorer general health (p = 0.013) and the presence of dementia (p < 0.010). A more advanced age (p = 0.036) and longer nursing-home stay (p = 0.048) had a negative effect on the DHI. Furthermore, gender (p = 0.037, in favour of women), poorer general health (p = 0.003), presence of dementia (p = 0.003), and the absence of natural teeth (p = 0.028) influenced poorer oral health. The factors most strongly influenced greater number of missing teeth were a more advanced age (p = 0.021) and longer nursing-home stay (p = 0.015). In terms of fewer filled teeth, a shorter nursing-home stay (p = 0.002) was the factor most strongly influenced this.

Conclusions

Poorer general health and the presence of apraxia and cognitive impairment are the main determinants for poorer oral hygiene and oral health among nursing-home residents. A longer nursing-home stay also seems to be relevant for oral health and denture hygiene.

Oral conditions in the community patient: part 2-systemic complications of poor oral health

Oral health has a symbiotic relationship with general health, with oral disease recognised to have an adverse effect on the overall systemic health of a patient. Deterioration in oral health has been shown to have an impact on the severity of chronic systemic diseases, nutrition, hydration and psychological and social wellbeing. Part 1 of this mini-series explored the common oral conditions that community patients may present with, and the role of the nursing team in aiding the prevention, diagnosis and management of these conditions. Following on from that, this article discusses the links between oral and general health, and preservation of a patient's quality of life. This article also aims to support nurses' knowledge on how to assess the oral health needs of patients, support oral care provision, how to access acute and elective dental services and signpost to additional supportive resources.

Caregiver-reported dementia as a predictor of oral health among patients receiving home-visit dental treatment: A retrospective cohort study

Objective

To assess caregiver‐reported dementia as a risk factor for retained roots, an indicator of poor oral hygiene, among patients receiving home‐visit dental treatment in Japan.

Methods

The medical records of 231 dentate patients who received home‐visit dental treatment (covered by public medical insurance) for more than 2 years were retrospectively analyzed. The number of teeth and retained roots at the initial and final examinations were obtained from the dental charts, and the “change in the number of retained roots from initial to final examination” was determined. The presence or absence of caregiver‐reported dementia, diabetes, and osteoporosis, as well as the level of long‐term care needed, were used as indicators of general health condition at the initial interview. Multiple regression analyses were conducted in five models that tested the association of independent variables (age, gender, observation period, general health, presence or absence of caregiver‐reported dementia at the initial interview) with changes in the number of retained roots.

Results

In all models, the presence of caregiver‐reported dementia at the initial interview was significantly associated with the change in the number of retained roots (p < .05). The adjusted coefficient of determination (R²) of model 5, which included all the predetermined independent factors, was .168.

Conclusions

Caregiver‐reported dementia may be a risk factor for an increase in the number of retained roots among patients who receive home‐visit dental treatment and may serve as an indicator of the need for regular and proactive oral hygiene management.

Prevention and management of periodontal diseases and dental caries in the older adults

As a result of aging populations, in the future, dental practitioners will be caring for more older adults than ever before. These older adults, especially in developed countries, will demand a greater number of dental services, driven by increased tooth retention and an expectation of excellent oral healthcare throughout the life course. Further, the global rise in the prevalence and incidence of chronic diseases will increase the risk and/or severity of oral diseases and add a layer of complexity to the management of oral diseases in older adults. More older adults will be at a higher risk of periodontal disease and root caries as a result of reduced tooth loss and edentulism. This article reviews information on periodontitis and root caries, oral diseases which reflect the cumulative risk of the individual, and which are best addressed through prevention. Oral healthcare providers must embrace the concept of lifelong emphasis on prevention, as well as participation as active members of a healthcare team which provides healthcare for older adults in various settings (eg, hospital/clinic-based care, community-based settings, and long-term care facilities). National guidelines that address oral health are being considered by some countries, and if these are implemented they will increase the accessibility to oral health for older adults. In parallel to this, revisions of existing older adult insurance schemes (eg, the inclusion of routine oral healthcare in the US Medicare program) would promote the maintenance of a functional dentition that is pain-free and conducive to general health. The opportunity exists to implement a holistic approach to oral health that will align oral health with general health and emphasize that true health can only be achieved with the inclusion of oral health.

Chewing Efficiency, Global Cognitive Functioning, and Dentition: A Cross-sectional Observational Study in Older People With Mild Cognitive Impairment or Mild to Moderate Dementia

Introduction: Previous studies suggest an association between poor mastication and cognitive impairment. The role of chewing efficiency and dentition in this relation is unclear. The aim was to examine global cognitive functioning and dentition as predictors for chewing efficiency, in older people with mild cognitive impairment (MCI) or dementia.

Methods: In this observational cross-sectional study, 136 people with MCI or dementia were included. The chewing efficiency was assessed with a two-colored chewing gum and analyzed with the Chewing Efficiency Analysis software. The level of global cognitive functioning was measured with the Mini Mental State Examination (MMSE) by trained clinical staff. An oral examination was performed by a dentist and included the number of present teeth, the number of occluding pairs, and the presence of prostheses. Age, gender, and educational years were derived from the medical records. Univariate and multivariate backward stepwise linear regression analyses were used to evaluate global cognitive functioning and dentition as predictors for chewing efficiency.

Results: The mean age of the participants was 82.1 (SD 5.8) years, and 74 (54.4%) were female. The participants had a median MMSE score of 22.4 (IQR 18.0–26.0) and a median Chewing Efficiency Analysis score of 0.46 (IQR 0.14–0.59). The median number of teeth was 13.0 (IQR 0.0–23.0), and the median number of occluding pairs was 0.0 (IQR 0.0–7.0). Sixty-four (47.4%) of the participants wore full prosthesis in the upper jaw. In univariate linear regression analyses, predictive factors for the Chewing Efficiency Analysis score were age, MMSE score, full prosthesis in the upper jaw, number of present teeth, and number of occluding pairs. In the multivariate model, full prosthesis in the upper jaw and number of occluding pairs were significant predictors for the Chewing Efficiency Analysis score. Participants with full prosthesis in the upper jaw had a lower Chewing Efficiency Analysis score than participants with natural dentition in the upper jaw.

Conclusion: Better mastication is associated with a higher number of occluding pairs. Full prosthesis in the upper jaw is related to a lower chewing efficiency. Global cognitive functioning is not associated with mastication in older people with MCI or mild-to-moderate dementia. This might be explained by sufficient capacity for compensation of reduced mastication in this group.

Oral Health and Care for Elderly People with Alzheimer's Disease

Dementia is one of the main causes of disability among elderly people. It is a progressive neurodegenerative disease that affects elderly people’s ability to perform daily living activities. Alzheimer’s disease is the main subtype of dementia and causes declining memory, reasoning, and communication skills. They also have behavioural and psychological symptoms, such as depression and aggression. It is essential for them to maintain good oral health, as oral health is an important and integral part of their general health. Neglecting oral health allows dental diseases to develop, and these diseases are difficult and costly to treat. However, dental diseases can be treated with ambulatory care rather than hospitalisation and emergency care. Elderly people should establish daily oral hygiene care routines during the early stages of Alzheimer’s disease. They should have regular dental examinations and early minimal interventions to prevent the need for extensive and complicated procedures. Maintaining oral health becomes challenging, however, when Alzheimer’s disease progresses to the middle and late stages. Because elderly people might forget or lose interest in keeping their teeth healthy, caretakers and community health workers may need to take over this task. Dentists should provide guidance on the maintenance of oral health, as the techniques used to provide this support vary depending on the elderly people concerned. The purpose of this paper is to provide an overview of oral health and the importance of oral care for elderly people with Alzheimer’s disease. The paper also discusses appropriate dental interventions and techniques for maintaining good oral health and helping people with Alzheimer’s to enjoy a satisfactory quality of life.

The relation of poor mastication with cognition and dementia risk: a population-based longitudinal study

We investigated the effect of poor masticatory ability on cognitive trajectories and dementia risk in older adults. 544 cognitively intact adults aged ≥50 were followed for up to 22 years. Cognitive domains (verbal, spatial/fluid, memory, and perceptual speed) were assessed at baseline and follow-ups. Dementia was ascertained according to standard criteria. Masticatory ability was assessed using the Eichner Index and categorized according to the number of posterior occlusal zones: A (all four), B (3-1), and C (none).

At baseline, 147 (27.0%) participants were in Eichner category A, 169 (31.1%) in B and 228 (41.9%) in C. After the age of 65, participants in Eichner category B and C showed an accelerated decline in spatial/fluid abilities (β: -0.16, 95% CI: -0.30 to -0.03) and (β: -0.15, 95% CI: -0.28 to -0.02), respectively. Over the follow-up, 52 incident dementia cases were identified. Eichner categories B or C were not associated with an increased risk of dementia, compared to category A (Hazard Ratio [HR]: 0.83, 95% CI: 0.39 to 1.76 and HR: 0.63, 95% CI: 0.30 to 1.29, respectively).

Poor masticatory ability is associated with an accelerated cognitive decline in fluid/spatial abilities, however it was not related to a higher risk of dementia.

Prevalence and associations of orofacial pain and oral health factors in nursing home residents with and without dementia

OBJECTIVES

determine and compare the prevalence of orofacial pain in older nursing home residents with and without dementia and explore the association between orofacial pain and health factors.

METHODS

cross-sectional study conducted in four UK nursing homes. We used the Orofacial-Pain Scale for Non-Verbal Individuals (OPS-NVI) to identify orofacial pain in residents with dementia. Residents who were able to communicate self-reported orofacial pain. A brief oral examination was conducted. Information on demographics, Clinical Dementia Rating, Charlson Comorbidity Index, Cohen Mansfield Agitation Inventory, Barthel Index, 5-level Euroqol 5 Dimension, Oral Health Impact Profile 14, Mini Nutritional Assessment Short Form and medication was collected. Chi-squared tests, independent sample t-tests and Mann-Whitney U-tests were used to compare outcomes between groups. Multivariable logistic regression was used to evaluate predictors of orofacial pain.

RESULTS

orofacial pain, assessed with the OPS-NVI, was present in 48.8% (95% confidence interval [C.I.] 36.1-50.7) of residents with dementia. Self-reported orofacial pain was present in 37.8% (95% C.I. 20.4-53.7) of residents with dementia and in 14.8% (95% C.I. 0.5-30.4) residents without dementia. Orofacial pain was significantly more prevalent in residents with dementia than those without (OPS-NVI; P = 0.002, self-report; P = 0.04). Having a soft diet, xerostomia, being dentate, and poor oral hygiene in dentate residents were significant predictors of orofacial pain in residents with dementia.

CONCLUSION

orofacial pain was more prevalent in residents with dementia. Oral health care should be part of routine care for residents, especially for those with dementia, to improve oral health and decrease the risk of developing orofacial pain.

Flossing Is Associated with Improved Oral Health in Older Adults

The effect of preventive oral habits is largely unexplored in older individuals. The purpose of this study was to evaluate the associations between home use of flossing and prevalence of periodontal disease and caries in older adults. Five-year incident tooth loss was also evaluated. Data on 686 individuals ≥65 y-old from the Piedmont 65+ Dental Study were examined including: 1) interproximal clinical attachment level (iCAL), 2) interproximal probing depth (iPD), 3) numbers of caries, and 4) missing teeth. Flossing behavior was evaluated according to the Periodontal Profile Class (PPC) system. Five-year follow-up data (n = 375) was evaluated for incident tooth loss. Dichotomous and categorical variables were analyzed using Pearson chi-square tests as well as covariate-adjusted Cochran-Mantel-Haenszel tests. Multiple linear regression compared clinical parameters based on flossing behavior. Elderly flossers had lower (mean, SE) %iCAL≥3 mm (38.2, 2.38 vs. 48.8, 1.56) and %iPD≥4 mm (8.70, 1.41 vs. 14.4, 0.93) compared to nonflossers (P ≤ 0.005). Flossers showed less coronal caries compared to nonflossers (P = 0.02). Baseline number of missing teeth (mean, SE) was 11.5 (0.35) in nonflossers compared to 8.6 (0.53) in flossers (P < 0.0001). Regular dental visitors had lower oral disease levels compared to episodic dental users. The majority of flossers classified into PPC-Stage I (health) whereas nonflossers classified as PPC-Stages V, VI, and VII (disease). At the 5-y follow-up visit, the average tooth loss for flossers was ~1 tooth compared to ~4 teeth lost for nonflossers (P < 0.0001). Among all teeth, molars showed the highest benefit (>40%) for flossing behavior (P = 0.0005). In conclusion, the extent of oral disease for older individuals was significantly less in flossers than in nonflossers. Flossers showed less periodontal disease, fewer dental caries, and loss of fewer teeth over a 5-y period. These findings further support flossing as an important oral hygiene behavior to prevent oral disease progression in older adults.

The Role of Periodontitis and Periodontal Bacteria in the Onset and Progression of Alzheimer's Disease: A Systematic Review

The evidence of a connection between the peripheral inflammatory processes and neurodegenerative diseases of the central nervous system is becoming more apparent. This review of the related literature highlights the most recent clinical, epidemiological, and in vitro studies trying to investigate possible connections between periodontal bacteria and the onset and progression of Alzheimer’s disease. This review was conducted by searching databases such as PubMed and Scopus using keywords or combinations such as Alzheimer’s Disease AND periodontal or dementia AND periodontitis OR periodontal. After eliminating overlaps and screening the articles not related to these issues, we identified 1088 records and proceeded to the selection of articles for an evaluation of the associative assumptions. The hypothesis suggested by the authors and confirmed by the literature is that the bacterial load and the inflammatory process linked to periodontal disease can intensify inflammation at the level of the central nervous system, favoring the occurrence of the disease. The analysis of the literature highlights how periodontal disease can directly contribute to the peripheral inflammatory environment by the introduction of periodontal or indirect pathogenic bacteria and proinflammatory cytokines locally produced at the periodontal level following bacterial colonization of periodontal defects.

Short-Term Effects of a Deterioration of General Health on the Oral Health of Nursing-Home Residents

Purpose

The purpose of this study was to identify how changes to general health might affect the oral health of nursing-home residents over a six-month period.

Materials and Methods

The study was conducted in nine nursing homes in Germany. Sociodemographic and general data were collected at baseline and after six months. Complete baseline and follow-up data were available for 114 participants. The Clinical Dementia Rating (CDR) and the Global Deterioration Scale (GDS) were used to identify the presence and, if applicable, severity of dementia among participants. The Apraxia Screen of TULIA (AST) was used to identify motor impairment. A comprehensive dental examination of each participant was also performed. The examination included the documentation of dental and denture status and the number of decayed, missing and filled teeth (DMF-T). In addition, dental and denture hygiene were quantitatively assessed using the Plaque Index (PI) and the Denture Hygiene Index (DHI), respectively. Global dental treatment needs were evaluated by use of the Oral Health Assessment Tool (OHAT). Univariate and multivariate linear regression models were compiled to analyse possible factors affecting the dependent target variables.

Results

During the study period, denture hygiene among the study population worsened by an average of 15%. The regression models detected that a more advanced age (in years) was associated with a less pronounced deterioration of denture hygiene as measured by use of the DHI (−0.806 per additional year of age; p = 0.030). Furthermore, an increase in the level of care needed (coefficient (C): −1.948; p = 0.002) and a more poorly graded assessment of general health compared with the value at baseline (C: 1.054; p = 0.026) were both associated with a deterioration of oral health as evaluated by use of the OHAT. In addition to these results, an increase in care needs was also associated with a deterioration of dental health as evaluated by use of the DMF-T (C: 0.966; p = 0.013).

Conclusion

In the short term, a deterioration of general health, including an increase in care needs, seems to be the predominant factor associated with a more pronounced deterioration of oral health among nursing-home residents.

Can oral health and oral-derived biospecimens predict progression of dementia?

Growing evidence indicates that oral health and brain health are interconnected. Declining cognition and dementia coincide with lack of self‐preservation, including oral hygiene. The oral microbiota plays an important role in maintaining oral health. Emerging evidence suggests a link between oral dysbiosis and cognitive decline in patients with Alzheimer's disease. This review showcases the recent advances connecting oral health and cognitive function during aging and the potential utility of oral‐derived biospecimens to inform on brain health. Collectively, experimental findings indicate that the connection between oral health and cognition cannot be underestimated; moreover, oral biospecimens are abundant and readily obtainable without invasive procedures, which may help inform on cognitive health.

Palliative Care in Advanced Dementia

Dementia syndrome is common and expected to increase significantly among older people and characterized by the loss of cognitive, psychological and physical functions. Palliative care is applicable for people with dementia, however they are less likely to have access to palliative care. This narrative review summarizes specifics of palliative care in advanced dementia. Most people with advanced dementia live and die in institutional care and they suffer a range of burdensome symptoms and complications. Shortly before dying people with advanced dementia suffer symptoms as pain, eating problems, breathlessness, neuropsychiatric symptoms, and complications as respiratory or urinary infections and frequently experience burdensome transitions. Pharmacological and nonpharmacological interventions may reduce symptom burden. Sensitive observation and appropriate assessment tools enable health professionals to assess symptoms and needs and to evaluate interventions. Due to lack of decisional capacity, proxy decision making is often necessary. Advanced care planning is an opportunity establishing values and preferences and is associated with comfort and decrease of burdensome interventions. Family carers are important for people with advanced dementia they also experience distress and are in need for support. Recommendations refer to early integration of palliative care, recognizing signs of approaching death, symptom assessment and management, advanced care planning, person-centered care, continuity of care, and collaboration of health care providers.
