Orofacial pain and its potential oral causes in older people with mild cognitive impairment or dementia

Oral pain and comorbidities in an edentulous older population: A k-prototypes cluster analysis

Non-odontogenic oral pain is prevalent among the older people and significantly impacts their quality of life. Non-odontogenic oral pain is usually persistent and accompanied by comorbidities such as psychosocial distress and sleep-related problems, which further complicate pain management. The relationship between non-odontogenic oral pain and comorbidities in the older people, however, has not been well documented. This study aimed to identify the factors associated with non-odontogenic oral pain in an edentulous older population and to subgroup this population based on the patterns of oral pain and its associated factors. In this cross-sectional study, data from completely edentulous individuals in the National Health and Nutrition Examination Survey for the period from 2017 to 2020 March (pre-pandemic) were analysed. Associations and correlations between oral pain and 46 other variables, including demographic, questionnaire, examination and laboratory data, were investigated using Pearson's chi-squared test and Spearman's rank correlation test. A p value of < 0.05 was considered statistically significant. Clustering of the data was performed using the k-prototypes algorithm, an unsupervised machine learning. Approximately 42% of the edentulous older people experienced oral pain. 'Having been told to take daily low-dose aspirin' was significantly associated with oral pain. Oral pain was positively correlated with depressive symptoms and excessive daytime sleepiness (EDS), and negatively correlated with diastolic blood pressure, red blood cell count, haemoglobin level and haematocrit. The k-prototypes algorithm identified a cluster characterised by frequent oral pain, depression and EDS. This study identified distinct patterns of comorbidities among edentulous older people living with oral pain.

Comparison of the oral health status of nursing home residents using the current and the newly developed interRAI oral health section (OHS-interRAI): a cross-sectional study

BACKGROUND

Regular dental l check-ups and good oral hygiene are challenging for nursing home residents, resulting in poor oral health. The interRAI instrument for Long-Term Care Facilities (LTCF) enables caregivers to evaluate residents' health, including oral health, and to integrate oral care into general care planning. Because the current oral heal1th section in the interRAI instruments does not accurately identify residents who need help with daily oral care or dental referral, the interRAI Oral Health Section (OHS-interRAI) was developed. The OHS-interRAI differs from the current section by including more items, response options and guidelines, photographs, instruction videos, and Collaborative Action Points to alert caregivers when oral care is needed. This study describes and compares residents' oral health status assessed by caregivers using the current section and the OHS-interRAI.

METHODS

This cross-sectional study includes baseline data of adults aged 65 years or older in Flemish and Dutch nursing homes, collected by professional caregivers (e.g., nurses, nurse aids, therapists). Assessments with the current section dated from October 2016 to January 2023, and with the OHS-interRAI from October 2020 to January 2023.

RESULTS

InterRAI assessments of 12,476 residents from 158 nursing homes with the current section were compared with those of 1212 residents from 37 nursing homes with the OHS-interRAI. The OHS-interRAI assessments showed more missing data. A higher proportion of oral health problems was detected with the OHS-interRAI compared to the current section for chewing function (13.7% vs. 6.8%), dry mouth (9.8% vs. 7.6%), teeth (22.1% vs. 16.6% ),and gums (7.8% vs. 3.1%). There was no significant difference in the proportion of residents with discomfort or pain in the mouth.

CONCLUSIONS

More missing OHS-interRAI data may be attributed to regulatory decisions on using the interRAI LTCF instrument. Caregivers identified more oral health problems with the OHS-interRAI, which may be due to its additional features, such as photographs and extensive instructions. The Collaborative Action Points included in the OHS-interRAI support continuity of care and enable integration of oral care into general care. Further research is needed to evaluate whether the OHS-interRAI accurately identifies residents who need help with daily oral hygiene or dental referral.

Oral hygiene self-care: Concept analysis for the development of a new nursing diagnosis

OBJECTIVE

This study aims to analyze the concept of oral hygiene self-care and develop a new problem-focused nursing diagnosis (ND) based on the NANDA-I terminology.

METHOD

A concept analysis was performed based on the Walker and Avant framework, including a scoping review phase according to the Joanna Briggs Institute guidelines. Searches were performed in PubMed, Cumulative Index to Nursing and Allied Health Literature, Scopus, Web of Science, Virtual Health Library, and specific gray literature databases. The development of the diagnostic structure followed the NANDA-I guidelines with a focus on Orem's self-care theory.

RESULTS

Including 51 studies, the analysis facilitated the formulation of attributes, antecedents, and consequences of oral hygiene self-care. The ND "Oral hygiene self-care deficit" was created and included 17 defining characteristics, 9 related factors, 5 associated conditions, and 5 high-risk populations. Two cases were constructed to illustrate the use of key terms.

CONCLUSIONS

The conceptual analysis provided insight into the concept of oral hygiene self-care and supported the structure of a new ND.

IMPLICATIONS FOR NURSING PRACTICE

This study contributes to the implementation of the nursing process by focusing on the identification of individuals with oral hygiene self-care deficit. It will facilitate the promotion of oral health, thereby impacting the individual's quality of life. In addition, it will aid in the development of public policy for the prevention of oral diseases.

Dentitions of Long-Term Care Residents: Tooth Types, Roles in Occlusion and Association with Dementia

Background/Objectives: Many older adults living in long-term care (LTC) environments have varying numbers of retained natural teeth. The objective of this study was to assess the disease findings based on tooth type and estimate the role of tooth types in occlusion. Methods: We conducted clinical oral examinations of 276 LTC residents. The disease findings were analyzed for each tooth type and to determine their associations with dementia. Results: In total, 67.8% of the participants had molar teeth. Premolars/canines were often present as residual roots and had caries. Deepened periodontal pockets and higher plaque index (PI) values for molars had odds ratios of 2.5 (95% confidence interval [CI] of 1.59-3.91) and 1.61 (95% CI of 1.29-2.02), respectively. Participants with dementia were more likely to have incisors and premolars/canines in the form of root remnants and higher PI scores for all tooth types (p ≤ 0.01), as well as more deepened periodontal pockets in all teeth (p = 0.029), than those without dementia. The median number of remaining molars per participant was 3 out of a maximum of 12 (95% CI 3.4-4.0); thus, they often lacked occlusal contact. Conclusions: The LTC residents' molars were more prone to periodontal problems, whereas their premolars/canines often had caries or were present in the form of root remnants, especially in the participants with dementia. People's teeth should be treated in an easy-to-maintain way before they move into LTC to enable daily oral hygiene measures and maintain oral health.

Oral Health Problems Among Flemish and Dutch Nursing Home Residents Assessed by Nondental Caregivers Using the Novel Oral Health Section for Inclusion in interRAI

Background and Objectives

Oral health of older adults in nursing homes is poor, which can negatively affect general health and well-being. Most oral health problems are preventable with good oral hygiene and regular dental check-ups. Caregivers can help improve residents' oral health through regular oral health assessments. The interRAI instrument used in Long-Term Care Facilities to evaluate older adults' health and well-being, has the potential to integrate oral care into general care planning. The recently optimized Oral Health Section for inclusion in the interRAI instruments (OHS-interRAI) enables nondental caregivers to identify residents requiring help with oral hygiene and/or a dental referral. This study reports the first data obtained using the OHS-interRAI, describing the oral health situation of older adults in Flemish and Dutch nursing homes.

Research Design and Methods

In this cross-sectional study, interRAI Long-Term Care Facilities data, including OHS-interRAI data, were collected from October 2020 to January 2023 and analyzed from 417 and 795 persons aged 65 years or older in Flemish and Dutch nursing homes, respectively.

Results

Most common oral health problems were poor oral hygiene and compromised teeth. Differences in oral health were found between Flemish and Dutch residents. Flemish residents had significantly more problems with chewing, dry mouth, oral and denture hygiene, and tongue condition than their Dutch counterparts. They also had a higher need for help with oral hygiene (19.4% vs 14.0%), and a dental referral (36.8% vs 20.9%). Older adults in Flemish nursing homes (20.3%) had significantly fewer dental check-ups than those in Dutch nursing homes (73.5%).

Discussion and Implications

The use of the OHS-interRAI by nondental caregivers identified at least one-third of the residents requiring help with oral hygiene and/or a dental referral. By means of trigger algorithms (Collaborative Action Points), the OHS-interRAI enables the integration of oral care into general care planning.

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%; I 2, 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.

Pain in non-communicative older adults beyond dementia: a narrative review

Aging is associated with an increased risk of developing pain, especially in the presence of concurrent chronic clinical conditions. Similarly, multimorbidity can affect the perception and ability of older adults to appropriately respond to and communicate pain, and there is a clinical heterogeneity in the processing of painful sensations in different neurological conditions. The present narrative review is aimed at assessing the prevalent diseases associated with poor communication and pain in older adults, together with the available diagnostic instruments for the clinical assessment of pain in such a vulnerable population. Dementia was the most described pathology identified in the current literature associated with poor communication in older adults affected by pain, along with Parkinson's disease and stroke. Notably, a common pattern of pain behaviors in these neurological disorders also emerged, indicating potential similarities in the clinical presentation and appropriate diagnostic workout. At the same time, there are many differences in the way patients express their pain according to their main neurological pathology. In addition to this, although a plethora of observation-based tools for pain in patients with dementia have been developed, there is no gold standard, and the clinical utility of such measurements is still largely unaddressed. Meanwhile, there is substantially no standardized observation-based tool for pain in non-communicative patients with Parkinson's disease, and only a few for stroke. Overall, the present narrative review provides an update on the prevalent diseases beyond dementia associated with a communicative disability and a painful condition in older adults.

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.

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.

Associations of oral health status and swallowing function with cognitive impairment in the aging population: a cross-sectional study

BACKGROUND

The purpose of this study was to investigate the relationships of oral health status and swallowing function with cognitive impairment in community-dwelling older adults from Changsha, Hunan Province, China.

METHODS

In this cross-sectional study, we analyzed the data of 215 participants aged ≥ 50 years which were retrieved from the Xiangya and Panasonic mild cognitive impairment (MCI) Study, a community-based study conducted among the residents of the urban areas of Hunan province in China. Demographic information of all participants was collected. We determined oral function by evaluating oral hygiene, oral dryness, occlusal force, tongue pressure, chewing function, swallowing function, remaining teeth number, and other indicators. The mini-mental state examination (MMSE) was used to screen for cognitive function. The relationship between each oral function evaluation item and cognitive function was investigated using correlation analysis. The associations between oral health status and swallowing function with cognitive impairment were inferred using multiple regression analysis.

RESULTS

The general characteristics of participants showed statistically significant correlation coefficients in number of teeth remaining (p = 0.003) and number of teeth lost (p < 0.0001). Almost half of the 25 participants (48%) were aged from 70-80 years. Only 25 older adults (11.6% of the participants) were determined to have cognitive impairment by MMSE sores less than 24. Tongue pressure in male participants was the only significant independent variable that was associated with cognitive impairment (p = 0.01971). The results indicate that male participants with lower MMSE scores had a relative deficiency in tongue pressure.

CONCLUSIONS

In this cross-sectional study, the oral health status and swallowing function of participants were in relatively good condition and showed low correlations with cognitive impairment. However, lower tongue pressures were associated with lower MMSE scores in males, indicating it could serve as a novel oral function index for evaluating cognitive impairment.

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.

Can high pain intensity and catastrophizing interfere with the cognitive performance of women with chronic pain related TMD? A cross-sectional study

OBJECTIVE

Interventions based on pain education and self-management are dependent on factors such as attention, memory, concentration, and executive function. To explore the relationship between cognitive performance and the variables pain intensity, central sensitization, catastrophizing, and hypervigilance in women diagnosed with chronic pain-related TMD.

METHODOLOGY

This is a cross-sectional study. A total of 33 women (mean age: 38±4.6 years; range: 18 to 66 years) with chronic pain-related TMD (myalgia and/or arthralgia) diagnosed according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Specific questionnaires were used to evaluate cognitive performance, overall pain intensity, central sensitization, hypervigilance, and pain catastrophizing. The data were analyzed using Pearson's correlation coefficient and backward stepwise multiple linear regression (statistical significance at 5% alpha).

RESULTS

Approximately 53% of the study sample showed decreased cognitive performance. High central sensitization, hypervigilance, and pain catastrophizing were observed. A significant negative correlation was observed between cognitive performance and hypervigilance (p=.003, r=-.49), cognitive performance and catastrophizing (p<.001, r=-.58), and cognitive performance and pain intensity (p<.001, r=-.58). Regarding the partial regression coefficients, only catastrophizing and pain intensity showed statistical significance (t=-2.12, p=.043; t=-2.64, p=.014, respectively), indicating a significant role in explaining cognitive performance at the sample.

CONCLUSION

High pain intensity and the presence of catastrophic thoughts regarding pain can predict impaired cognitive performance in women with chronic pain-related TMD. Management strategies addressing psychosocial dimensions such as reducing catastrophizing and ensuring complete understanding of the condition are important.

Decision-Making concerning Involuntary Oral Care for Older Individuals with Dementia

Many older individuals with dementia (OIWD) show care-resistant behavior for oral care. Providing care despite resistance is considered to be involuntary care. Although involuntary care should be minimized, in some OIWD it may be necessary to avoid health risks. This study aims to assess the attitudes of healthcare providers with regard to involuntary oral care provision for OIWD who show care-resistant behavior. An online questionnaire consisting of general questions and case specific questions was administered via social media and networking to individuals involved in the oral care of OIWD. A total of 309 participants were included in this study. The outcomes of the questionnaires were categorized per case. In all cases, a discrepancy was seen between the assessment of oral health problems as potentially harmful (range: 73.1-93.5%) and the willingness to provide involuntary care (range: 31.1-63.4%). Hence, many healthcare providers are aware of the subsequent potential health risks related to not providing care, but are still reluctant to provide involuntary oral care. Therefore, many OIWD who show care-resistant behavior potentially do not receive the necessary oral care they require.

Measurement properties, interpretability and feasibility of instruments measuring oral health and orofacial pain in dependent adults: a systematic review

Background

Dependent adults have been shown to have a greater experience of oral health deterioration and orofacial pain. This is partly because their non-dental caregivers may not easily identify oral health problems and orofacial pain experienced by them. Thus, this systematic review aimed to investigate measurement properties, interpretability and feasibility of instruments assessing oral health and orofacial pain in dependent adults, which can be used by the non-dental caregivers to establish oral care plans for those who are dependent upon them.

Methods

Seven bibliographic databases were searched: MEDLINE, Embase, CINAHL, CENTRAL, HTA, OATD and OpenGrey. Citations and reference lists of the included studies were also manually searched. Two authors independently screened titles and abstracts, and then full texts. A quality assessment of included studies was conducted independently by two authors using the COSMIN Risk of Bias checklist. The best evidence synthesis method was used to synthesise results from different studies for each measurement property per measurement instrument by integrating the overall rating for each measurement property per measurement instrument with its quality level of evidence.

Results

Nineteen eligible studies were included, which reported the development, measurement properties’ evaluation, interpretability and feasibility of nine oral health and three orofacial pain measurement instruments. Methodological quality of the included studies ranged from very good to inadequate. None of the identified measurement instruments has been adequately and comprehensively tested.

Conclusions

While several measurement instruments were identified in this systematic review, more evidence is needed to be able to more comprehensively evaluate these instruments. Among those identified, the OPS-NVI demonstrated sufficient construct validity, while the OHAT and the THROAT demonstrated sufficient reliability. These instruments therefore have potential for future use with more confidence once other measurement properties, interpretability and feasibility have been sufficiently tested and evaluated.

Health policy analysis on barriers and facilitators for better oral health in German care homes: a qualitative study

OBJECTIVES

To assess possible health policy interventions derived from the theoretical domains framework (TDF) by studying barriers and facilitators on the delivery of oral healthcare and oral hygiene in German care homes using a behavioural change framework.

DESIGN

Qualitative correlational study to evaluate a national intervention programme.

SETTING

Primary healthcare in two care homes in rural Germany.

PARTICIPANTS

Eleven stakeholders participating in the delivery of oral healthcare (hygiene, treatment) to older people, including two care home managers, four section managers, two nurses/carers and three dentists.

INTERVENTIONS

Semistructured interviews conducted in person in the care homes or by phone. A questionnaire developed along the domains of the TDF and the Capabilities, Opportunities and Motivations influencing Behaviours model was used to guide the interviews. Interviews were transcribed and systematised using Mayring's content analysis along the TDF.

RESULTS

860 statements were collected. We identified 19 barriers, facilitators and conflicting themes related to capabilities, 34 to opportunities and 24 to motivation. The lack of access to professional dental care was confirmed by all stakeholders as a major limitation hampering better oral health.

PRIMARY OUTCOME

A range of interventions can be discussed with the methodology we utilised. In our interviews, lack of dentists willing to treat patients at these facilities was the most discussed barrier for improving oral health of nursing home residents.

SECONDARY OUTCOMES

Dentists highlighted the need for better incentives and facilities to deliver oral healthcare in these institutions. Differences with urban settings regarding access to healthcare were frequently discussed by our study participants.

CONCLUSIONS

Within our sample, greater capacitation of care home staff, better financial incentives for dentists and increased cooperation between the two stakeholders should be considered when designing interventions to tackle oral health of care home residents in Germany.

Oral exercises significantly improve oral functions in people with mild and moderate dementia: a randomized controlled study

BACKGROUND

There have been no standard protocols of oral exercises for maintaining and improving oral function for people with dementia.

OBJECTIVE

This study aimed to determine the effects of home-based oral exercises on the oral function of people with mild to moderate dementia.

METHODS

Twenty-two participants at King Chulalongkorn Memorial Hospital were randomly assigned to exercise group (n = 11) or control group (n = 11). The exercise group was instructed to do three home-based oral exercises, consisting of tongue-strengthening, oral diadochokinesis (ODK), and mouth-opening exercises, for 3 months, while the control group received advice on oral health care. The maximum tongue pressure (MTP) was the primary outcome. MTP, ODK rates of /pa/, /ta/, /ka/, modified water swallowing test (MWST), and oral moisture were measured at baseline, and after 1, 2, and 3 months of training. The generalized estimating equation analysis was used to evaluate the effects of oral exercises on the oral function.

RESULTS

The MTP and all ODK rates in the exercise group were significantly increased after 3 months of training. There were significant interaction effects between time and intervention in MTP and all ODK rates. No significant interaction effects between time and intervention in oral moisture were found. The MWST scores in both groups did not change through the end of study and no adverse effects were reported.

CONCLUSION

Home-based oral exercises were found to be effective for improving tongue strength and tongue-lip motor function in people with mild to moderate dementia.

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.

Interrater reliability and concurrent validity of oral/dental items in the resident assessment instrument minimum data set 2.0

OBJECTIVE

To examine interrater reliability and concurrent validity of oral/dental items in the Resident Assessment Instrument Minimum Data Set (RAI-MDS) 2.0.

BACKGROUND

RAI-MDS is a standardised instrument used in nursing to determine health status and nursing needs. The extent to which oral/dental items in the RAI-MDS describe dental treatment needs concerning oral health has been questioned.

MATERIALS AND METHODS

This study evaluated the interrater reliability (dentist vs. nurse) and validity of oral/dental items in the Swiss version of RAI-MDS 2.0 (areas: K-nutritional status, L-oral/dental status) using professional oral examinations as a benchmark. Data of 168 residents of five long-term care facilities in the canton of Zurich, Switzerland, were collected within 1 year between October 2017 and December 2018. The statistical evaluation used descriptive statistics and Cohen's kappa (95% CI).

RESULTS

RAI-MDS items K1a, chewing (κ 0.098, 95% CI: 0.004-0.19); K1c, pain (κ 0.039, 95% CI: -0.03 to 0.11); L1a, debris (κ 0.117, 95% CI: 0.02-0.21); L1c, dental status (κ 0.229, 95% CI: 0.12-0.34); L1d, dental disease (κ 0.129, 95% CI: 0.02-0.24); L1e, periodontal diseases (κ -0.005, 95% CI: -0.07 to -0.03); and L1f, daily cleaning (κ -0.031, 95% CI: -0.05 to -0.01) showed weak or no agreement, whereas L1b, denture status (κ 0.634, 95% CI: 0.52-0.75), showed substantial agreement.

CONCLUSION

Oral/dental items in RAI-MDS lack reliability and validity. Recognition of oral health situation/treatment needs by nursing staff does not seem to be possible with the current version of this tool.

Update and review of the gerodontology prospective for 2020's: Linking the interactions of oral (hypo)-functions to health vs. systemic diseases

New lines of evidence suggest that the oral-systemic medical links and oral hypo-function are progressively transcending beyond the traditional clinical signs and symptoms of oral diseases. Research into the dysbiotic microbiome, host immune/inflammatory regulations and patho-physiologic changes and subsequent adaptations through the oral-systemic measures under ageism points to pathways leading to mastication deficiency, dysphagia, signature brain activities for (neuro)-cognition circuitries, dementia and certain cancers of the digestive system as well. Therefore, the coming era of oral health-linked systemic disorders will likely reshape the future of diagnostics in oral geriatrics, treatment modalities and professional therapies in clinical disciplines. In parallel to these highlights, a recent international symposium was jointly held by the International Association of Gerontology and Geriatrics (IAGG), Japanese Society of Gerodontology (JSG), the representative of USA and Taiwan Academy of Geriatric Dentistry (TAGD) on Oct 25th, 2019. Herein, specific notes are briefly addressed and updated for a summative prospective from this symposium and the recent literature.

Interventions to improve oral health of older people: A scoping review

OBJECTIVES

A range of interventions have been tested to improve oral health of older people. We performed a scoping review to map interventions' aims, outcome measures and findings, and to locate them on different levels of care.

DATA

We systematically screened for (1) controlled studies on (2) people over 65 years of age, (3) comparing at least two interventions to improve oral health. Interventions were summarized according to their aims and the employed intervention type, mapped on their level of action, and classified as primary/secondary/tertiary prevention.

SOURCES

Studies retrieved via MEDLINE, EMBASE, CINAHL.

STUDY SELECTION

Eighty-one studies (published 1997-2019, conducted mainly in high-income countries) were included. Sample sizes varied (n = 24-1987). Follow-up was 0.25-60 months. Most studies (64/81) found a statistically significant benefit of the intervention. A total of 13 different aims were identified, and a range of intervention types employed (e.g. educational interventions, professional oral healthcare, restorative treatment, fluoride application and, generally, dentifrices, mouthwashes, chewing gums/food supplements). Most studies were located on the carer/patient level (56/81 studies) or the system/policy-maker level (44/81). The majority of studies aimed for primary prevention (64/81).

CONCLUSIONS

Oral health improvement interventions are widely studied. However, study aims, methods and outcome measures are highly heterogeneous, which limits the ability for robust conclusions. Current research focusses on primary prevention on the level of patients/carers or system/policy-maker level. Future studies may want to consider interventions on dentists' level focussing on secondary prevention. These studies should rely on a core set of comprehensive, standardized set of outcome measures.

CLINICAL SIGNIFICANCE

While specific interventions seem efficacious to improve older people's oral health, the current body of evidence is neither comprehensive (significant gaps exists in relevant levels of the care process) nor comparable enough to draw robust conclusions.

The Impact of Dementia on Oral Health and Dental Care, Part 1: Setting the Scene for Dental Care Provision

There are over 850,000 people living with dementia in the UK and this figure is expected to rise to over a million by 2021. Increasingly, oral healthcare professionals in primary care will see more patients affected by dementia at varying stages of the disease, and it is therefore crucial that they have a basic understanding of the disease and how these patients can be managed in a primary care environment. The first article in this series of two provides a definition of dementia and describes the symptoms of the disease along with the key issues related to oral health, such as oral pain. Oral pain can have far reaching consequences, but identifying it can be problematic, particularly in the latter stages of the disease. This article will therefore cover how to diagnose pain in patients with dementia. Information is also provided about how to make dental surgeries more 'dementia friendly'.

Self-reported oral health problems and the ability to organize dental care of community-dwelling elderly aged ≥75 years

Background

It is unclear how many community-dwelling elderly (≥75 years) experience oral health problems (e.g. pain, dry mouth, chewing problems) and how they manage their dental care needs. This study aimed to assess self-reported oral health problems in elderly who are frail or have complex care needs, and their ability to organize dental care when reporting oral pain.

Methods

Three thousand five hundred thirty-three community-dwelling elderly participating in the “Embrace” project were asked to complete questionnaires regarding oral status and oral health problems. Frailty was assessed with the Groningen Frailty Indicator (GFI). Intermed for Elderly Self-Assessment (IM-E-SA) was used to determine complexity of care needs. Next, elderly who reported oral pain were interviewed about their oral pain complaints, their need for dental care, and their ability to organize and receive dental care. For statistical analyses Chi²-tests and the one-way ANOVA were used.

Results

One thousand six hundred twenty-two elderly (45.9%) completed the questionnaires. Dry mouth (11.7%) and oral pain (6.2%) were most frequently reported. Among the elderly reporting oral pain, most were registered at a local dentist and could go there when needed (84.3%). Robust elderly visited the dentist independently (87%), frail (55.6%) and complex (26.9%) elderly more often required assistance from caregivers.

Conclusions

Dry mouth and oral pain are most reported oral health problems among community-dwelling elderly. Elderly with complex care needs report most oral health problems. In case an elderly seeks dental treatment to alleviate an oral pain complaint, most elderly in this study were able to organize dental care and transport to the dentist. Frail and complex elderly often need assistance from caregivers to visit the dentist. Therefore caretakers should keep in mind that when frailty progresses, visiting a dentist may become more and more difficult and the risk for poor oral health increases.

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.

Functional Adaptation of Oromotor Functions and Aging: A Focused Review of the Evidence From Brain Neuroimaging Research

“Practice makes perfect” is a principle widely applied when one is acquiring a new sensorimotor skill to cope with challenges from a new environment. In terms of oral healthcare, the traditional view holds that restoring decayed structures is one of the primary aims of treatment. This assumes that the patient’s oromotor functions would be recovered back to normal levels after the restoration. However, in older patients, such a structural–functional coupling after dental treatment shows a great degree of individual variations. For example, after prosthodontic treatment, some patients would adapt themselves quickly to the new dentures, while others would not. In this Focused Review, I argue that the functional aspects of adaptation—which would be predominantly associated with the brain mechanisms of cognitive processing and motor learning—play a critical role in the individual differences in the adaptive behaviors of oromotor functions. This thesis is critical to geriatric oral healthcare since the variation in the capacity of cognitive processing and motor learning is critically associated with aging. In this review, (a) the association between aging and the brain-stomatognathic axis will be introduced; (b) the brain mechanisms underlying the association between aging, compensatory behavior, and motor learning will be briefly summarized; (c) the neuroimaging evidence that suggests the role of cognitive processing and motor learning in oromotor functions will be summarized, and critically, the brain mechanisms underlying mastication and swallowing in older people will be discussed; and (d) based on the current knowledge, an experimental framework for investigating the association between aging and the functional adaptation of oromotor functions will be proposed. Finally, I will comment on the practical implications of this framework and postulate questions open for future research.

Oral Health Status and Need for Oral Care in an Aging Population: A Systematic Review

Background. The world population is aging. This phenomenon is accompanied by an increase in the number of elderly with dementia, whose oral hygiene care is a challenge. Objective. This paper presents a literature review of oral health status and the need for oral care in people with dementia, as compared to people without dementia and also of the relationship between periodontal disease and cognitive impairment. Methods. A systematic review was conducted in PubMed, CINAHL, and the Cochrane Library. Fifty-six articles met the inclusion criteria and were consequently included for quality assessment and data extraction. Results. No significant differences were found between both groups with regard to the number of present teeth, DMFT Index, edentulousness/use of denture, and orofacial pain. Coronal/root caries and retained roots were more common in people with dementia than in those without dementia. Most of the participants with dementia presented gingival bleeding or inflammation and they suffered from the periodontal disease more than people without dementia. Conclusions. Poor oral health is a common condition among the elderly with dementia. The education process of caregivers might improve the oral health status of people with dementia. Finally, periodontal disease might contribute to the onset or progression of dementia.

Oral health care for patients with Alzheimer's disease: An update

Alzheimer's disease and related disorders (ADRD) are among the age-associated chronic conditions that are most challenging to health care systems around the globe, as patients with dementia require full-time, intensive care for multiple years. Oral health care is negatively impacted by cognitive decline, and consequently poor oral health is common among people with ADRD. Poor oral health status is linked with many undesirable consequences for the well-being of people with ADRD, from excruciating local pain to life-threatening conditions, as aspiration pneumonia. In this paper, the authors provide an update on the most current concepts about Alzheimer's disease epidemiology, etiology, and management, current oral health care for patients with Alzheimer's disease, oral health promotion strategies for this population, as well as current research and future direction for improving oral health care for patients with Alzheimer's disease. It concludes that oral health care should be included in the patient's routine health care as early as possible in the progression of Alzheimer's disease for preventing rapid oral health deterioration. Establishing oral hygiene routines and providing dental treatment that is customized to the patients' individual needs and disease stage are important to achieve good oral health outcomes and prevent quality of life decline.

Orofacial pain and its potential oral causes in older people with mild cognitive impairment or dementia

Background

The number of people with dementia and natural dentition is growing. As dementia progresses, the degree of self‐care decreases and the risk of oral health problems and orofacial pain increases.

Objectives

To examine and compare the presence of orofacial pain and its potential causes in older people with Mild Cognitive Impairment (MCI) or dementia.

Methods

In this cross‐sectional observational study, the presence of orofacial pain and its potential causes was studied in 348 participants with MCI or dementia with all levels of cognitive impairment in two outpatient memory clinics and ten nursing homes.

Results

Orofacial pain was reported by 25.7% of the 179 participants who were considered to present a reliable pain self‐report (Mini‐Mental State Examination score ≥14 points), while it could not be determined in people with more severe cognitive impairment. The oral health examination of the 348 participants indicated that potential painful conditions, such as coronal caries, root caries, tooth root remnants or ulcers were present in 50.3%. There was a significant correlation between the level of cognitive impairment and the number of teeth, r = 0.185, P = 0.003, teeth with coronal caries, r = −0.238, P < 0.001, and the number of tooth root remnants, r = −0.229, P = 0.004, after adjusting for age.

Conclusions

This study indicated that orofacial pain and its potential causes were frequently present in participants with MCI or dementia. Therefore, a regular oral examination by (oral) healthcare providers in people with MCI or dementia remains imperative, even if no pain is reported.
