Efficacy of regular professional brushing by a dental nurse for 3 months in nursing home residents-A randomized, controlled clinical trial

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.

Older people's preferences and expectations of preventive oral care in the home

OBJECTIVE

The aim of the study was to assess older people's preferences and expectations for preventive oral care in their own home.

BACKGROUND

With increasing age, the use of dental services declines and oral health becomes secondary, yet good oral health contributes to quality of life and has a positive impact on general health. Thus, the healthcare system should offer a care structure in which oral health can be maintained into old age. To provide patient-centred care, patient preferences in additional preventive oral care need to be explored.

MATERIALS AND METHODS

In this qualitative study, semi-structured interviews were conducted with community-dwelling individuals aged ≥65 years to understand their preferences and expectations for oral care in a home-based setting. Interviews were recorded, transcribed verbatim and analysed thematically.

RESULTS

Fourteen dental patients were included. Three overarching themes were identified. The desire for independence was predominant when addressing their future capability to perform oral hygiene. When addressing possible future oral health support, self-determination and independence were important to them. Concerns about dependency in inpatient care facilities and the associated reduction in oral care were evident. Frequency, costs and the practice environment played a decisive role when thinking about additional preventive measures for their future.

CONCLUSION

The results of this study provide important information about older people's preferences and expectations for preventive oral care in the home environment and relate to three core themes of (1) changes in oral hygiene skills and perceptions, (2) support and (3) organisational factors. These must be considered when planning and implementing preventive oral care.

Evaluation of the extent of plaque removal and users' experience of alternative toothbrushes: A randomized single-blind crossover study

INTRODUCTION

In residential care, tooth brushing with a manual toothbrush can be challenging because of technical difficulties, time consumption and poor patient cooperation, resulting in a sub-optimal cleaning. The study aimed at comparing the efficiency in plaque removal, brushing time and users' experience between three toothbrushes: a single-headed conventional manual toothbrush, a triple-headed manual toothbrush and a U-shaped electric toothbrush.

METHODS

This was a single-blind crossover study with three pre-post-test conditions. Participants were 26 dental students divided into fixed pairs to play the role of caregivers and care receivers. Pre/post plaque scores were determined by two independent investigators according to the Quigley-Hein Plaque Index (QHI). Questionnaires evaluated participants' experiences. Statistical tests of significances of differences and ANOVA were performed.

RESULTS

Results showed that plaque removal was more effective for the manual toothbrush and the triple-headed toothbrush compared to the U-shaped electric toothbrush (p < 0.001). Brushing time was the longest for the single manual toothbrush (149 s). The U-shaped electric toothbrush showed significantly better results for aspects related to comfort and salivation. The manual and triple-headed toothbrush showed better results for aspects related to cleanliness and motivation to use.

CONCLUSION

Notwithstanding its favourable comfort, tooth plaque removal is not enhanced by a U-shaped electric toothbrush. The triple-headed and single-headed toothbrushes reduced plaque more substantially than the U-shaped toothbrush. In addition, the triple-headed manual toothbrush was not only effective in plaque removal, but also had a shorter brushing time and was easy to use, being an adequate alternative for care-dependent patient groups.

Oral health assessment in institutionalized elderly: a scoping review

When elderly become frail and in need for complex care, they can no longer live independently at home and may be admitted to nursing homes. Various studies have shown that oral health in this population is remarkably poor, which may lead to distressing situations and impacts quality of life. A variety of definitions or descriptions for oral health is used. Without a uniform parameter, it is impossible to determine whether oral health in institutionalized elderly is actually improving or deteriorating over time, as well as the effect of (preventive) interventions. In search for an adequate and clinically applicable parameter to determine oral health in this specific patient group, this scoping review aims to give an overview of the currently used parameters for determining oral health in institutionalized elderly. Ninety different parameters were identified, and 50 parameters were solely used by one study. Only 4 parameters were frequently used (in > 20 studies). The relevance of these parameters for this specific patient group is discussed. To aid the planning and commissioning of future research and patient care, there is an urgent need for an adequate and uniform parameter for oral health determination in institutionalized elderly.

Prevalence, and Risk Indicators of Coronal and Root Caries in Mexican Older Adults in Nursing Homes

Background

Several factors are associated with coronal and root caries in older persons. The purpose of this study was to determine the experience, prevalence, and risk indicators (socioeconomic, sociodemographic, and dental variables) of coronal and root caries in older persons residing in nursing homes in Mexico.

Methods

A cross-sectional study was carried out in 227 dentate participants with natural teeth. Convenience sample, where all dentate residents were invited to participate. The dependent variables were coronal caries and root caries, which were determined through an oral clinical examination. The independent variables were sociodemographic factors, location, type of center, surfaces free of dental biofilm and calculus, surfaces with recession, retainers in contact with surfaces with recession, xerostomia, smoking, and the previous use of dental services. The binary logistic regression model was used in the analysis.

Results

The mean age of the participants in this study was 77.7±8.8 years, and 69.2% were women. Moreover, 71.8% live in long-term care facilities, and 48.0% live in Mexico City. The prevalence of coronal and root caries was found to be 67.8% and 50.7%, respectively. Being male and living in Mexico City were risk indicators for coronal caries, and with a 1% increase in surfaces with no biofilm, the risk decreased by 2%. Being widowed, having government or no social security, denture retainers, and coronal caries were risk indicators for root caries, while the utilization of dental services indicated lower risk.

Conclusion

Several variables that differ in nature were found to be risk indicators for coronal and root caries. Coronal caries increases the risk of root caries. Prevention should be aimed at identifying persons at higher risk, and dental care should be improved for persons living in long-term care institutions.

The Effect of Domiciliary Professional Oral Care on Root Caries Progression in Care-Dependent Older Adults: A Systematic Review

With care dependency, untreated root caries lesions (RCLs) and irregular dental visits are common. RCLs, if left untreated, could lead to pain, tooth loss, difficulties eating, and impact on general health. Therefore, there is a need for prevention and effective treatment for RCLs, and especially in those with care dependency. The aim of this systematic review was to investigate the effect of domiciliary professional oral care on root caries development and progression, in comparison with self-performed or nurse-assisted oral care. A literature search was conducted in four databases in November 2022. Two authors independently screened the literature throughout the review process. Five of the identified studies were found to be relevant. Four of these were assessed as having moderate risk of bias and were included in the review, while one study had high risk of bias and was excluded from further analyses. Due to heterogenicity of the included studies (and of the interventions and outcomes), no meta-analysis or synthesis without meta-analysis (SWiM) was performed. The participation of dental personnel performing mechanical plaque removal and fluoride, or chlorhexidine application seems beneficial for care-dependent older adults with risk of RCLs development and progression. However, future studies are needed.

Interdisciplinary Approaches to Deal with Alzheimer's Disease-From Bench to Bedside: What Feasible Options Do Already Exist Today?

Alzheimer's disease is one of the most common neurodegenerative diseases in the western population. The incidence of this disease increases with age. Rising life expectancy and the resulting increase in the ratio of elderly in the population are likely to exacerbate socioeconomic problems. Alzheimer's disease is a multifactorial disease. In addition to amyloidogenic processing leading to plaques, and tau pathology, but also other molecular causes such as oxidative stress or inflammation play a crucial role. We summarize the molecular mechanisms leading to Alzheimer's disease and which potential interventions are known to interfere with these mechanisms, focusing on nutritional approaches and physical activity but also the beneficial effects of cognition-oriented treatments with a focus on language and communication. Interestingly, recent findings also suggest a causal link between oral conditions, such as periodontitis or edentulism, and Alzheimer's disease, raising the question of whether dental intervention in Alzheimer's patients can be beneficial as well. Unfortunately, all previous single-domain interventions have been shown to have limited benefit to patients. However, the latest studies indicate that combining these efforts into multidomain approaches may have increased preventive or therapeutic potential. Therefore, as another emphasis in this review, we provide an overview of current literature dealing with studies combining the above-mentioned approaches and discuss potential advantages compared to monotherapies. Considering current literature and intervention options, we also propose a multidomain interdisciplinary approach for the treatment of Alzheimer's disease patients that synergistically links the individual approaches. In conclusion, this review highlights the need to combine different approaches in an interdisciplinary manner, to address the future challenges of Alzheimer's disease.

Models of provider care in long-term care: A rapid scoping review

INTRODUCTION

One of the current challenges in long-term care homes (LTCH) is to identify the optimal model of care, which may include specialty physicians, nursing staff, person support workers, among others. There is currently no consensus on the complement or scope of care delivered by these providers, nor is there a repository of studies that evaluate the various models of care. We conducted a rapid scoping review to identify and map what care provider models and interventions in LTCH have been evaluated to improve quality of life, quality of care, and health outcomes of residents.

METHODS

We conducted this review over 10-weeks of English language, peer-reviewed studies published from 2010 onward. Search strategies for databases (e.g., MEDLINE) were run on July 9, 2020. Studies that evaluated models of provider care (e.g., direct patient care), or interventions delivered to facility, staff, and residents of LTCH were included. Study selection was performed independently, in duplicate. Mapping was performed by two reviewers, and data were extracted by one reviewer, with partial verification by a second reviewer.

RESULTS

A total of 7,574 citations were screened based on the title/abstract, 836 were reviewed at full text, and 366 studies were included. Studies were classified according to two main categories: healthcare service delivery (n = 92) and implementation strategies (n = 274). The condition/ focus of the intervention was used to further classify the interventions into subcategories. The complex nature of the interventions may have led to a study being classified in more than one category/subcategory.

CONCLUSION

Many healthcare service interventions have been evaluated in the literature in the last decade. Well represented interventions (e.g., dementia care, exercise/mobility, optimal/appropriate medication) may present opportunities for future systematic reviews. Areas with less research (e.g., hearing care, vision care, foot care) have the potential to have an impact on balance, falls, subsequent acute care hospitalization.

Oral Health Disorders in Parkinson's Disease: More than Meets the Eye

Despite clinical evidence of poor oral health and hygiene in Parkinson’s disease (PD) patients, the mouth is often overlooked by both patients and the medical community, who generally focus on motor or psychiatric disorders considered more burdensome. Yet, oral health is in a two-way relationship with overall health—a weakened status triggering a decline in the quality of life. Here, we aim at giving a comprehensive overview of oral health disorders in PD, while identifying their etiologies and consequences. The physical (abnormal posture, muscle tone, tremor, and dyskinesia), behavioral (cognitive and neuropsychiatric disorders), and iatrogenic patterns associated with PD have an overall detrimental effect on patients’ oral health, putting them at risk for other disorders (infections, aspiration, pain, malnutrition), reducing their quality of life and increasing their isolation (anxiety, depression, communication issues). Interdisciplinary cooperation for prevention, management and follow-up strategies need to be implemented at an early stage to maintain and improve patients’ overall comfort and condition. Recommendations for practice, including (non-)pharmacological management strategies are discussed, with an emphasis on the neurologists’ role. Of interest, the oral cavity may become a valuable tool for diagnosis and prognosis in the near future (biomarkers). This overlooked but critical issue requires further attention and interdisciplinary research.

Effectiveness of brushing teeth in patients with reduced oral hygiene by laypeople: a randomized, controlled study

Background

To evaluate the success of plaque reduction after external toothbrushing by instructed laypeople versus dental professionals using either a manual or powered toothbrush. Longitudinal, randomized, parallel-group intervention study in periodontitis patients with reduced oral hygiene quality undergoing anti-infective therapy. Patients were randomly and equally assigned to one of four groups: laypeople using a manual or powered toothbrush or dental professionals using a manual or powered toothbrush. Plaque reduction (Quigley–Hein-Index (QHI), Marginal Plaque Index (MPI)), gingivitis (papilla bleeding index), and cleaning time (seconds) were investigated.

Results

Thirty-nine patients participated in the study. Neither the choice of toothbrush (p = 0.399) nor the use of a dental professional (p = 0.790) had a significant influence on plaque levels achieved. However, multivariate modeling indicated statistically significant differences in the external cleaning time between brushing groups, with longer time required by laypeople (p = 0.002) and longer use of the powered toothbrush (p = 0.024).

Conclusion

When the ability to carry out personal oral hygiene is reduced, external brushing by dental professionals or instructed laypeople who meet previously defined criteria such as sufficient personal oral hygiene at home could help to fill the emerging dental care gap. A combination of oral hygiene approaches adapted to the individual needs of the patients in need of external help is necessary for optimum oral hygiene.

Dental plaque control strategies for the elderly population: A scoping review

OBJECTIVE

To review the scientific literature and identify dental plaque control strategies focussed on elderly people that improve plaque indices.

DESIGN

Scoping review (Joanna Briggs protocol).

DATA SOURCES

Individual search strategies developed for six databases. The selection of the manuscripts in two phases: title and abstract review, and complete review.

ELIGIBILITY CRITERIA

Studies on interventions for plaque control in elderly people (60y+). Epidemiological studies and those focussed on caregivers, health professionals and periodontal maintenance therapies were excluded.

RESULTS

The initial search yielded 2803 studies, 26 were included. The results were classified into: exclusively chemical (10), educational (9), exclusively mechanical (6), and combined mechanical and chemical (1). The studies reported different types of interventions: sugarless chewing gum, chlorhexidine (CHX) in different preparations and concentrations, mouthwash based on essential oils, stannous/sodium fluoride dentifrice and lactoferrin/lactoperoxidase tablets. Additionally, conventional and alternative toothbrushes and professional brushing were tested. Educational interventions included oral hygiene guidance, verbal information, and demonstrations of dental and denture cleaning procedures, and lifestyle changes. Many studies have reported strategies that improve dental plaque indices but without statistical significance when compared to control groups. Promising results were found with the use of CHX, sugarless chewing gum, professional brushing and educational strategies with demonstration, but the results were not long-lasting.

CONCLUSION

The literature reports that mechanical, chemical and educational strategies have some efficacy in dental plaque control in the elderly population. The results should be viewed with caution, considering the type of intervention (isolated or combined) and the maintenance of the results obtained.

How accurate is the assessment of certified nursing assistants on resident's oral self-care function in three North Carolina assisted-living facilities?

AIMS

To examine the association between the assessments of certified nursing assistants (CNAs) on resident's oral self-care function and resident's oral hygiene outcomes in three North Carolina assisted-living (AL) facilities.

METHODS AND RESULTS

Sixty-five dentate AL residents were included in this secondary analysis. CNAs were asked to rate the AL residents' overall oral self-care function using a 6-point Likert scale. Their assessments were then compared with the objective, performance-based Dental Activities Test and the oral hygiene and gingival health measures. The analysis showed that nearly 90% of the participants presented with at least one untreated decayed or broken tooth. On average, nearly two-thirds of the surfaces were covered by soft deposits (Debris Index = 1.83, SD = 0.60). Generalized mild to moderate inflammation (Gingival Index = 1.51, SD = 0.53) commonly presented on residents' gingiva. CNAs were able to accurately identify the residents with substantial impairment in oral self-care function, yet they tended to overestimate the oral self-care function of residents with mild to moderate impairment. CNAs assessments were also not significantly correlated with residents' oral hygiene measures.

CONCLUSION

CNAs failed to identify and provide assistance to AL residents with impaired oral self-care function, contributing to poor oral oral hygiene in these vulnerable individuals.

Effects of Domiciliary Professional Oral Care for Care-Dependent Elderly in Nursing Homes - Oral Hygiene, Gingival Bleeding, Root Caries and Nursing Staff's Oral Health Knowledge and Attitudes

Purpose

The primary aim was to describe the effects for nursing home residents of monthly professional cleaning and individual oral hygiene instruction provided by registered dental hygienists (RDHs), in comparison with daily oral care as usual. The secondary aim was to study the knowledge and attitudes among nursing staff regarding oral health care and needs.

Patients and Methods

In this randomised controlled trial (RCT), 146 residents were recruited from nine nursing homes in Regions of Stockholm and Sörmland and were randomly assigned (on nursing home level) to either intervention group (I; n=72) or control group (C; n=74). Group I received monthly professional cleaning, individual oral hygiene instructions and information given by an RDH. Group C proceeded with daily oral care as usual (self-performed or nursing staff-assisted). Oral health-related data was registered with the mucosal-plaque score index (MPS), the modified sulcus bleeding index (MSB), and root caries. The nursing staff’s attitudes and knowledge were analysed at baseline and at six-month follow-up. Statistical analysis was performed by Fisher’s exact test and two-way variance analysis (ANOVA).

Results

Improvements were seen in both Group I and Group C concerning MPS, MSB and active root caries. The nursing staff working with participants in Group I showed significant improvements regarding the Nursing Dental Coping Beliefs Scale (DCBS) in two of four dimensions, oral health care beliefs (p=0.0331) and external locus of control (p=0.0017) compared with those working with Group C. The knowledge-based questionnaire showed improvement (p=0.05) in Group I compared with Group C.

Conclusion

Monthly professional oral care, combined with individual oral health care instructions, seems to improve oral hygiene and may reduce root caries among nursing home residents. This may also contribute to a more positive attitude regarding oral hygiene measures among nursing home staff, as compared with daily oral care as usual.

Effectiveness of a Mouth Care Program Provided by Nursing Home Staff vs Standard Care on Reducing Pneumonia Incidence: A Cluster Randomized Trial

Importance

Pneumonia affects more than 250 000 nursing home (NH) residents annually. A strategy to reduce pneumonia is to provide daily mouth care, especially to residents with dementia.

Objective

To evaluate the effectiveness of Mouth Care Without a Battle, a program that increases staff knowledge and attitudes regarding oral hygiene, changes mouth care, and improves oral hygiene, in reducing the incidence of pneumonia among NH residents.

Design, Setting, and Participants

This pragmatic cluster randomized trial observing 2152 NH residents for up to 2 years was conducted from September 2014 to May 2017. Data collectors were masked to study group. The study included 14 NHs from regions of North Carolina that evidenced proportionately high rehospitalization rates for pneumonia and long-term care residents. Nursing homes were pair matched and randomly assigned to intervention or control groups.

Intervention

Mouth Care Without a Battle is a standardized program that teaches that mouth care is health care, provides instruction on individualized techniques and products for mouth care, and trains caregivers to provide care to residents who are resistant and in special situations. The control condition was standard mouth care.

Main Outcomes and Measures

Pneumonia incidence (primary) and hospitalization and mortality (secondary), obtained from medical records.

Results

Overall, the study enrolled 2152 residents (mean [SD] age, 79.4 [12.4] years; 1281 [66.2%] women; 1180 [62.2%] white residents). Participants included 1219 residents (56.6%) in 7 intervention NHs and 933 residents (43.4%) in 7 control NHs. During the 2-year study period, the incidence rate of pneumonia per 1000 resident-days was 0.67 and 0.72 in the intervention and control NHs, respectively. Neither the primary (unadjusted) nor secondary (covariate-adjusted) analyses found a significant reduction in pneumonia due to Mouth Care Without a Battle during 2 years (unadjusted incidence rate ratio, 0.90; upper bound of 1-sided 95% CI, 1.24; P = .27; adjusted incidence rate ratio, 0.92; upper bound of 1-sided 95% CI, 1.27; P = .30). In the second year, the rate of pneumonia was nonsignificantly higher in intervention NHs. Adjusted post hoc analyses limited to the first year found a significant reduction in pneumonia incidence in intervention NHs (IRR, 0.69; upper bound of 1-sided 95% CI, 0.94; P = .03).

Conclusions and Relevance

This matched-pairs cluster randomized trial of a mouth care program compared with standard care was not effective in reducing pneumonia incidence at 2 years, although reduction was found during the first year. The lack of significant results in the second year may be associated with sustainability. Improving mouth care in US NHs may require the presence and support of dedicated oral care aides.

ORAL HEALTH IN NURSING HOMES: WHAT WE KNOW AND WHAT WE NEED TO KNOW

A "silent epidemic" of oral diseases is afflicting older adults. Older adults develop coronal caries at "approximately one new cavity per year". Despite the rapidly growing older adult population, no recent data exist for adults aged ≥ 75 years. Oral disease impacts physical, psychological, and social well-being through pain, diminished function, and reduced quality of life. People of color disproportionately experience oral disease, yet little is known about racial/ethnic disparities in older adults. In the United States, the Health and Human Services Oral Health Strategic Framework proposed concrete steps to eliminate oral health disparities. Notably absent from this strategic plan is explicit consideration of nursing home residents. In the United States, federal regulations require nursing homes to evaluate oral health needs and facilitate access to dental care. Compliance to the regulations is unknown. Data are urgently required to provide essential information for program planning and evaluation on "racial and ethnic minorities, rural populations, and the frail elderly".

The underestimated problem of oral Candida colonization-An observational pilot study in one nursing home

Objectives

Older people are at increased risk of intraoral yeast colonization. In this observational case series, we assessed Candida colonization among nine nursing home residents to investigate possible correlations with their individual characteristics, general health parameters, and oral care. We also described the effect of professional dental cleaning (PDC) including prosthesis cleaning on colonization cases.

Materials and methods

General clinical and oral health was assessed in nine residents, and samples were taken from six oral mucosa sites or prosthetic surfaces. PDC was performed to achieve macroscopically clean results, and residents were re-examined 2 weeks later.

Results

We found that six residents were intraorally colonized with Candida albicans; four also had Candida glabrata. Prostheses were particularly infected. Dementia, multimorbidity, and presence of prostheses reduced oral hygiene ability; requiring assistance for oral hygiene care was a risk indicator for Candida colonization. PDC reduced C. albicans (at the expense of increased C. glabrata) but was not optimal for maintaining Candida reduction.

Conclusion

In this pilot study, Candida colonization is prevalent among nursing home residents, especially those with cognitive impairment, multimorbidity, or reduced oral hygiene capacity. Potential negative effects on general health necessitate diagnostic and therapeutic guidelines. PDC alone did not maintain the reduction in Candida colonization; additional methods for daily oral care are necessary.

Efficacy of regular professional brushing by a dental nurse for 3 months in nursing home residents-A randomized, controlled clinical trial

Objectives

The oral health of nursing home residents is poor for various reasons. Many require help for oral hygiene. Regular professional brushing by a dental nurse should improve oral hygiene. This study aimed to determine the efficacy of regular tooth brushing by a dental nurse on the oral health of nursing home residents.

Methods

This controlled trial randomized participants (n = 50; mean age 83 ± 8 years) to brushing by a dental nurse every 2 weeks for 3 months (n = 25; test group) or oral hygiene procedures performed/controlled by nursing home staff (n = 25; control group). Personal, general and oral health, as well as various oral hygiene parameters—plaque index (PI), gingivitis index (GI), papilla bleeding index (PBI), oral hygiene index (OHI) and Volpe‐Manhold Index (VMI)—were evaluated at baseline, after initial professional dental cleaning and before last brushing.

Results

At baseline, oral health was impaired according to investigated indices in both groups. After professional brushing for 3 months, there were improvements in PI, GI and PBI, with significant increases compared with the control group in OHI and VMI (P = 0.017 and P < 0.001, respectively). Among the control group, the number of teeth decreased while the root caries index increased (P = 0.002 between groups).

Conclusions

Regular professional brushing every 2 weeks by a dental nurse can be recommended for nursing homes residents to improve oral health parameters and to help reduce root caries incidence as a basis to preserve the number of teeth. Such oral hygiene procedures will maintain and improve the oral health of nursing home residents.
