Domiciliary dental care among homebound older adults: A nested case-control study in Japan

Oral Health Assessment for Older Residents in Long-Term Care Facilities Using Video Recording by a Mobile Electronic Device

BACKGROUND/OBJECTIVES

Many older adults who require long-term care need oral health management. However, access to dental care is limited, and connecting older patients with dental professionals is a future challenge. Therefore, the development of a remote oral health assessment system is required. This study aimed to investigate the usefulness of video-based oral health assessments in older adults residing in facilities.

METHODS

This study comprised 60 older adults residing in facilities who consented to dental home visit treatment by the Department of Oral Function Management at Showa University Dental Hospital between July 2021 and December 2022. The Oral Health Assessment Tool (OHAT) was used to evaluate the oral health status at the facilities by one dentist. The concordance of the oral health assessments conducted by this dentist at the facilities (OHAT-B) was compared with those conducted by the same dentist (OHAT-V1) and two other dentists (OHAT-V2 and V3) using approximately 1 min video recordings of the oral cavity taken with a mobile electronic device.

RESULTS

On the OHAT total score, the intraclass correlation coefficient (ICC [1.1]) for OHAT-B and V1 was 0.931; the ICC (2.1) was 0.889 when compared with V2 and 0.788 when compared with V3. Moreover, the comparison between V2 and V3 showed high agreement, with an ICC (2.1) of 0.750.

CONCLUSIONS

This study revealed that the oral health assessment of older adults residing in facilities using video recordings of the oral cavity taken with a mobile electronic device may be possible, suggesting the possibility of remote oral health assessment.

Factors Associated With the Suspension of Domiciliary Dental Care for Older Adults During the First Wave of the Coronavirus Disease 2019 (COVID-19) Pandemic: A Comparative Study in the Japanese Local Government

Objective The novel coronavirus has reduced the availability of dental services, including domiciliary dental care. The suspension of dental treatment worsens the dental condition. However, the impact on domiciliary dental care during the coronavirus disease 2019 (COVID-19) pandemic remains unclear. Therefore, the aim of this study is to determine the impacts of the COVID-19 pandemic on domiciliary dental care and associated factors. Materials and methods This comparative study used Japanese prefectural claims data, including data from older adults who utilized domiciliary dental care. We compared the suspension of dental treatment during the firstwave of the COVID-19 pandemic with that before the COVID-19 pandemic. The outcome was the completion of four consecutive months of treatment. The chi-squared test, t-test, and logistic regression were applied. Result Approximately 23.4% of participants suspended home dental services during the first wave of the COVID-19 pandemic, whereas 11.7% suspended these services before COVID-19. Logistic regression clarified the effect of the following variables (during the first wave of COVID-19 vs. before COVID-19): care need level of long-term care was 1-5 (=severe) (odds ratio (OR): 0.92 vs. no significance (NS)), visit by hospital dentists (OR: 1.83 vs. NS), volume of patients in the visited place (2-9 people, OR: NS vs. 0.72; over 10 people, OR: 0.58 vs. 0.32), planned physicians' visit (OR: 0.71 vs. 0.77), and taxed income per population (OR: NS vs. 1.00). Discussion Domiciliary dental care, especially those in care facilities, were a vulnerable population during the pandemic. This may contribute to the delivery of domiciliary dental care during any future pandemics.

Provision of domiciliary dental service to residential aged care facilities: A 3-year descriptive summary

AIM

This cross-sectional descriptive study described the oral health status and types of domiciliary dental treatment received by residents living in residential care after an oral health assessment (OHAT).

METHODS

Twenty-one facilities were recruited where consenting participants received OHAT followed by a referral for further domiciliary dental treatments. Data were captured and stored as Reach-OHT database where 2017-2019 data were analyzed.

RESULT

Overall, 88% of residents consented. 69.1% were referred for treatment after completion of OHAT. More than half had one or more caries; 40% showed sign of periodontal disease; a higher proportion of dentate participants had an unsatisfactory level of oral cleanliness. Of those received domiciliary dental treatment, diagnostic and preventive service was the combination most frequently provided. These comprised an average of 71.9% of total treatment provided across the 3-year period.

CONCLUSION

This study contributes to the understanding and knowledge around the provision of domiciliary dental services in residential care. A large number of older people in residential care can be assessed and treated through a domiciliary service pathway. As the vast majority of services provided were diagnostic, preventive, and restorative care, the feasibility of utilizing the skillset of the entire dental team should be explored.

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

BACKGROUND

Previous studies have suggested that tea consumption may have a positive impact on oral health. However, the effects of different tea types on oral health remain unclear. Therefore, this study aimed to determine the association between residual teeth and consumption habits of different types of tea (green tea, black tea, oolong tea, and scented tea) in older adults.

METHODS

We conducted a secondary analysis using data from the Chinese Longitudinal Healthy Longevity Survey in 2018. In a sample of 6,387 older adults, we performed logistic regression analysis to examine the relationship between persistent tea consumption and oral health according to sex and brushing frequency. The indices for particularly healthy oral health and relative health were set at more than 20 teeth and more than 10 teeth, respectively.

RESULTS

The study included 2,725 males and 3,662 females, both aged 65 and older. Among individuals with more than 20 teeth, drinking green tea significantly improved oral health in men (adjusted odds ratio [ORs]: 1.377; 95% confidence interval [CI]: 1.082-1.752) and drinking black tea significantly improved the oral health of women (ORs: 2.349, 95%CI: 1.028-5.366). In the daily brushing group, green tea had a significant beneficial effect on increasing the number of teeth in men and black tea had a significant beneficial effect in women. Among individuals with more than 10 teeth, drinking green tea significantly improved oral health in men (ORs: 1.539; 95% CI: 1.209-1.959) and drinking green tea and scented tea significantly improved the oral health of women (ORs: 1.447, 95%CI: 1.052-1.991; ORs: 1.948, 95%CI: 1.137-3.340). In the daily brushing group, consumption of green tea and black tea had significant beneficial effects on increasing the number of teeth in men, whereas that of green tea, black tea, and scented tea had significant beneficial effects in women.

CONCLUSION

Long-term green tea consumption in males and black tea consumption in females were significantly associated with maintaining functional dentition (≥20 teeth). Similarly, long-term green tea consumption in males and green tea and scented tea consumption in females were associated with avoiding severe tooth loss (≥10 teeth). Furthermore, in the daily tooth brushing group, long-term consumption of black tea was associated with avoiding severe tooth loss in both sexes. However, tea consumption alone had no effect on oral health without good brushing habits.

Changes in Gloss Alteration, Surface Roughness, and Color of Direct Dental Restorative Materials after Professional Dental Prophylaxis

In the context of optimizing dental care for patients who are elderly, the purpose of this in vitro study was to evaluate the surface gloss (with a micro-area gloss meter) of, surface roughness (with a compact surface roughness measuring instrument) of, and color change (with a dental colorimeter) in two commercially available injectable resin-based composites (Estelite Universal Flow (EUF) and Beautifil Flow Plus F00 (BFP)) as well as two glass-ionomer cements (GC Fuji II LC CAPSULE (FLC) and GC Fuji IX GP EXTRA CAPSULE (FGP)), before and after dental prophylaxis. After 24 h, the surfaces of each specimen were polished at 2500 rpm with a prophy brush (Mersage Brush, Shofu) and one-step prophylaxis paste (Prophy Paste Pro, Directa): under 100 or 300 gf load, and for 10 or 30 s, 4× cycles of cleaning. After mechanical cleaning, conditions were found for a significant reduction in the gloss level (EUF, BFP, or FLC; p < 0.05) and a significant increase in surface roughness (BFP; 300 gf load, 10 s × four cycles of cleaning). Overall, the longer time or higher prophylaxis load tended to decrease the surface gloss. However, the observed change in surface roughness varied between the restorative materials. There was no color change post-prophylaxis.

A Qualitative Evaluation of the Implementation of an Oral Care Program in Home Care Nursing

An Oral Care Program (OCP) was implemented in home care nursing teams in a northern province of the Netherlands to improve the oral health and hygiene of older people who make use of formal home care in 2018-2019. The aim of the current study was to evaluate the experiences of the stakeholders involved (older people, home-care nurses and dental hygienists) and to report the experienced impact of OCP, with a qualitative approach. Three dental hygienists, nine home care nurses, and eight older people were interviewed with semi-structured interviews, which were audio recorded, transcribed and analyzed using thematic analysis. The codes derived were grouped into nine main themes. OCP was experienced as mostly positive by all stakeholders involved. The educational part lead to more awareness towards oral care, but should be repeated regularly. Personalized oral care plans for older people were experienced positively, however, obtaining oral care behavior changes appeared to be difficult. Collaboration between dental hygienists and home care nurses lead to a positive experience from both sides The method and intensity of collaboration varied between the teams. To provide better access to oral health care for older people in the community, a long term collaboration between home care nursing teams and dental care professionals in their working area should be established.

Evaluation of an Oral Care Program to Improve the Oral Health of Home-Dwelling Older People

The aim of this study was to evaluate the impact of the implementation of an Oral Care Program on home care nurses’ attitudes and knowledge about oral health (care) and the impact on older people’s oral health. A pre–post study, without a control group, was conducted. A preventive Oral Care Program (OCP) was designed, focusing on home care nurses and older people, in collaboration with dental hygienists. Implementation was measured with questionnaires at baseline and after 6 months for home care nurses; for older people, implementation was measured at baseline and after 3 months with the Oral Health Assessment Tool and a questionnaire about oral (self) care between January 2018 and September 2019. Although the study design has limitations, the oral health of older people improved significantly after 3 months and the OCP was most beneficial for people with full dentures. The OCP improved knowledge and attitude of home care nurses. The program fitted well with the daily work routines of home care nurses. Individual-centered care plans for older people, education of home care nurses and the expertise of the dental hygienists have added value in home care nursing. Future implementations should focus on older people with natural teeth.

Factors Affecting Hospitalization and Death of Older Patients Who Need Long-Term Care—The Necessity of the Support for Dysphagia in Home Dental Care

The demand for home dental care is increasing, but how it should be involved in the continuation of life at home for elderly people who need care has not been examined. Therefore, we examined whether items examined by dentists can affect hospitalization and death. The study included 239 patients with oral intake. They were divided into regular and non-regular diet groups, and ages, nutritional statuses, activities of daily living (ADLs), Charlson Comorbidity Indexes (CCI) and swallowing functions were compared. The nutritional statuses and ADLs of the three groups at the first visit and after one year were compared. The groups included those with stable, declined and improved diet forms. Factors influencing hospitalization and death over three years were examined. Nutritional status, swallowing function, CCI and ADLs were worse in the non-regular diet group. The declined diet form group had lower ADL levels and nutritional statuses at the first visit. A proportional hazards analysis showed significant differences in the changes in diet form for the stable and declined groups related to hospitalization (hazard ratio (HR): 6.53) and death (HR: 3.76). Changes in diet form were thought to affect hospitalization and death, and it is worthwhile to assess swallowing function in home dental care.

The implementation of domiciliary dental care from a university hospital: A retrospective review of the patients and performed treatments in central Taiwan from 2010 to 2020

BACKGROUND/PURPOSE

People who suffer with chronic illness, functional impairment, or cognitive impairment are not easily to visit dental clinics. Domiciliary dental care (DDC) can provide the feasible alternative for these clients. In this study, we first reported the DDC services from a university hospital in central Taiwan from 2010 to 2020.

MATERIALS AND METHODS

This retrospective study collected the DDC data from Department of Dentistry, Chung Shan Medical University Hospital, Taichung, Taiwan. The data including age, sex, geographic locations, place of residence, grade of disability, and type of dental treatment for the patients were obtained and analyzed.

RESULTS

A total of 419 patients (168 females and 251 males) who received dental treatment were included in the study. The average age was 57.4 years old. The total DDC services were up to 2444 visits. The top of place of residence for DDC is patient's home (231/419; 55.13%). Scaling was the most common type of dental treatment for DDC (317/419; 75.67%). The male patients whose age <60 years old had received more DDC (p = 0.002). The profound grade of disability had higher DDC in age <60 years old group (p < 0.001).

CONCLUSION

Taken together, this study demonstrates the demographic data of DDC in central Taiwan. The results may be valuable for governmental policy to improve the availability of DDC and in turn to facilitate oral health in this specific group of dental patients.

Domiciliary dentistry clinics: a multiple case study in the province of Quebec, Canada

BACKGROUND

The demand for more flexible and person-centered models of oral healthcare delivery is increasing and while mobile and domiciliary dental services have the potential to increase access to oral healthcare among dependent elderly and people with disabilities; the uptake of this service model by dentists remains low. Therefore, the aim of this study was to understand how existing domiciliary dental services operate within a particular context.

METHODS

We used a qualitative descriptive multiple case study design. We studied three independent domiciliary dentistry clinics in the province of Quebec, Canada. We completed observations of 27 domiciliary visits, four of which were in private homes and the remaining 23 in LTCFs. We also conducted semi-structured interviews with dental professionals, patients, and caregivers. We performed a qualitative content analysis using a deductive/inductive coding framework.

RESULTS

We presented a detailed description of the physical and service features of the studied cases. Physical features included the set-up of the mobile clinics, the portable equipment used, and the domiciliary locations of visits. For service features, we described the roles, attitudes, and interactions among those involved on both the providers' and recipients' sides, as well as, the logistical and financial aspect of the domiciliary dental services.

CONCLUSIONS

Despite variations in setup and years of practice, the three mobile clinics had similar physical and service features. They also faced common logistic challenges but were able to provide services and respond to the high demand for domiciliary dental services. Additional research in different contexts would further contribute to building evidence-based models to help increase the uptake of this type of practice by current and future dental professionals.

The use of Japanese long-term care insurance claims in health services research: current status and perspectives

This study aims to evaluate the current status and perspectives on the use of Japanese long-term care (LTC) claims databases for research. We conducted a comprehensive literature search of PubMed and the Japan Medical Abstracts Society (Ichushi-Web), focusing on LTC claims data analyses published between 2000 and 2020. We summarized the study characteristics, database characteristics, and the research areas related to health services that were studied. In total, 86 journal articles (12 in Japanese and 74 in English) were included in our review. A particularly remarkable increase in the number of publications from 2016 to 2020 was observed. We extracted more publications with combined databases (n = 64) than those that only used a single source of the LTC claims databases (n = 22). More than half of the studies analyzed healthcare expenditure, healthcare utilization, and quality of care which were relevant to health services research. The most frequently mentioned limitation was the lack of validation in variables stored in the LTC claims databases. In conclusion, the LTC claims databases could serve as important sources of information for the evaluation of healthcare delivery, quality of care, and LTC policy.

Dental implant status in elderly individuals requiring domiciliary dental care in Japan

Background

The presence of implants is a significant burden not only for dentists but also for caregivers and families of elderly individuals requiring nursing and domiciliary dental care. However, few reports have assessed the status of domiciliary dental care or measures employed to deal with related issues. Hence, we aimed to evaluate the dental implant status in elderly patients requiring nursing and domiciliary dental care and to determine the suitable measures for overcoming the associated limitations. A questionnaire was mailed to 1000 dentists who provided domiciliary dental care in the Tokyo metropolitan area of Japan. The questions were classified into three categories: basic information of the dentists, actual implant status of patients requiring domiciliary dental care, and implants in an aging society.

Results

The response rate was 36.5%. Approximately 2% of patients requiring domiciliary dental care were implant patients. Many implant-related problems were associated with insufficiency or difficulty in cleaning around the implant, resulting in peri-implantitis. Prosthetic and more serious complications such as implant body fracture or loss were reported and frequently managed by routine follow-ups, cleaning the area around the implant, scaling and polishing, and/or pharmacological modalities. Oral care mainly involved simple toothbrushing instructions, which was not adequate.

Conclusions

Our findings suggest the necessity of simplifying the oral environment and making oral care a simple task before aging individuals require nursing and domiciliary dental care.

What do we know about portable dental services? A scoping review

BACKGROUND

Delivering dental care to patients in their home or residential institutions is known as "portable dentistry". The demand for portable dental services is on the rise, but dentists remain reluctant to adopt portable practices.

OBJECTIVES

To explore the literature on portable dental services and understand (a) the process of planning and delivering portable dental services and (b) the benefits and challenges of portable dentistry for service providers and patients.

METHODS

A systematic scoping search was conducted. We retrieved 3994 documents, 28 of which were included in the final synthesis. Three authors read the papers and conducted thematic content analyses independently.

RESULTS

We present a synthesis of the literature and proposed a model of portable dentistry containing three levels with the patient is at the centre surrounded by concentric rings representing the dentist (dental team) and society. At each of these levels, our model is further subdivided into three components: 1) organisation of the service; 2) arrival and set-up of the service; and 3) delivery of the service. In addition, each level includes 1) human factors, which are related either to the dental professional or the patient; 2) non-human factors, which refer to either the equipment or the physical environment; and 3) financial factors, which are related to cost and remuneration.

CONCLUSIONS

We propose a model for portable dentistry that dentists and dental educators interested in this practice should find useful.

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.
