Associations of instrumental activities of daily living and handgrip strength with oral self-care among home-dwelling elderly 75+

Oral status of older adults receiving home medical care: A cross-sectional study

AIM

This study examined the oral status and the presence of teeth requiring treatment among older adults receiving home medical care.

METHODS

This cross-sectional study was conducted at a Japanese dental clinic specializing in geriatric treatment. We recruited older adults receiving home medical care in the community who had begun to receive domiciliary dental care. The Japanese version of the Oral Health Assessment Tool (OHAT-J), as well as the presence of teeth requiring extraction and the need for assistance in maintaining oral hygiene were used to evaluate the participants' oral health and its association with other items.

RESULTS

Ninety-three participants (44 male and 49 female, median age: 87.0 years) were surveyed. The median OHAT-J score was 6. The duration since the previous dental visit was 23 months. Sixty-two (73.8%) of 84 participants with ≥1 natural tooth had severe caries or teeth with severe mobility that required extraction. Logistic analysis revealed that requiring assistance in maintaining oral hygiene, mild dementia, severe dementia, and depression were significantly associated with an OHAT score of ≥6.

CONCLUSIONS

Older adults receiving home medical care had poor oral health, with approximately 70% of them requiring tooth extraction. The need for assistance in maintaining oral hygiene and poor mental status contribute to poor oral health. Geriatr Gerontol Int 2024; 24: 706-714.

Influence of visual acuity, manual dexterity and handgrip strength on oral and denture hygiene ability of non-frail older people: Development of the Gerostomatological Assessment Battery

BACKGROUND

Due to the heterogeneity of older people, it is difficult to identify reliable factors influencing oral health.

OBJECTIVE

The aim was to illustrate the influence of visual acuity, manual dexterity, and handgrip strength on the oral and denture hygiene ability of older non-frail people.

METHODS

In a cross-sectional study, conducted at a specialized dental clinic, at baseline, all participants received professional prophylaxis and instruction on daily oral and denture hygiene regimes for a 6-week intervention period. Data on the Quigley and Hein modified plaque index (QHI), respectively, the Denture Hygiene Index (DHI), visual acuity, manual dexterity and handgrip strength in non-frail participants (≥ 65 years) were collected. Recruitment was done within the clinic's patient clientele and within the staff (control cohort).

RESULTS

Women showed significantly better manual dexterity than men (Mann-Whitney U, p = .01), while women's mean handgrip strength was significantly lower (Mann-Whitney U, p < .01). Manual dexterity (Mann-Whitney U, p = .003) and handgrip strength (Mann-Whitney U, p = .052) were associated with age. However, visual acuity, manual dexterity and handgrip strength had no influence on oral or denture hygiene.

CONCLUSION

Visual acuity, manual dexterity and handgrip strength have no influence on oral and denture hygiene ability in older non-frail people. Further studies should investigate whether these factors also have no influence on oral and denture hygiene in vulnerable older patients. Therefore, an assessment tool for the evaluation of potential influencing factors of oral and denture hygiene is proposed in a dental context. This Gerostomatological Assessment Battery (G-AB) can be used as a helpful tool to check the individual cognitive function and comprehension, dental therapy approaches and their individual adaption.

Oral health-related quality of life among home-dwelling older people with and without domiciliary care

OBJECTIVES

The aim was to compare oral health-related quality of life (OHRQoL) between home-dwelling older people with and without domiciliary care when adjusted for gender, education, use of dental services and removable dental prostheses.

BACKGROUND

OHRQoL of home-dwelling older people with and without domiciliary care is a neglected area of research, with few studies having been conducted.

MATERIALS AND METHODS

A secondary analysis was conducted on the Finnish Health 2011 interview data. Home-dwelling participants (age ≥ 70) with or without domiciliary care were included (n = 758). OHRQoL was measured with the Oral Health Impact Profile questionnaire (OHIP-14) calculating three outcomes: prevalence of at least one impact reported: "occasionally," "fairly often" or "very often" (OFoVo), severity as mean sum score and mean of the seven OHIP-14 dimensions. These were evaluated by use of domiciliary care using logistic and negative binomial regression analyses.

RESULTS

Domiciliary care clients tended to have poorer OHRQoL than non-clients (severity mean 4.33 vs 4.11, P = .057), especially men (6.71 vs 4.15, P = .027), and reported more psychological discomfort than non-clients (mean 1.10 vs 0.82, P = .039). The use of removable dental prostheses was the strongest predictor (OR 2.84, P < .001) of poor OHRQoL.

CONCLUSION

Domiciliary care clients tended to report poorer OHRQoL, especially with regard to psychological discomfort dimension than non-clients. Thus, support of oral hygiene and regular utilisation of oral health services should be part of domiciliary care among older people to enhance OHRQoL.

Relationship between oral health behaviour and handgrip strength: a cross-sectional study with 7589 Korean adults

Objective: This cross-sectional study investigated the relationship between handgrip strength and oral health behaviours among Koreans.Methods: The data of 7589 individuals (3384 men and 4205 women) aged ≥19 years who participated in the Korea National Health and Nutrition Examination Survey 2014-2015 were analyzed. Oral health behaviour was assessed based on the number of daily toothbrushing sessions and the use of secondary oral-care products. The association between oral-health behaviour and handgrip strength was investigated adjusting for confounders. Multivariable logistic regression analysis was performed (α = 0.05).Results: The proportion of participants diagnosed with sarcopenia was significantly higher in the group with poor oral-health behaviours. After adjusting for confounders including age, the adjusted odds ratios and 95% confidence intervals of female participants with low handgrip strength in groups toothbrushing thrice or more per day, twice per day, and once or less per day were 1 (reference), 1.18 (0.99-1.4), and 1.24 (0.89-1.71), respectively. There were significantly more participants with low handgrip strength in the group that did not use secondary oral products for both sexes.Conclusions: Oral health behaviour is associated with handgrip strength among adults. Poor oral self-care habits may constitute a risk indicator for low muscle strength.

Oral care practices of long-term care home residents and caregivers: Secondary analysis of observational video recordings

AIMS AND OBJECTIVES

To describe the proportion of toothbrushing task steps, long-term care residents had an opportunity to complete; the duration and quality of toothbrushing by both residents and caregivers; and the feedback caregivers provided.

BACKGROUND

Poor oral health is widespread among older adults in long-term care homes; however, little is known about their actual oral health practices.

DESIGN

Secondary analysis of video recordings.

METHODS

A total of 58 video-recorded sessions were analysed from two long-term care homes in Canada. Eligible residents had at least one natural tooth, required oral care assistance, had Alzheimer's disease and understood English. Eligible caregivers spoke English and had worked for at least 1 year with people with dementia. Toothbrushing success was identified by the resident's participation in, and completion of, nine toothbrushing steps. Total time spent brushing teeth was calculated by summing the duration of time spent brushing teeth. Quality was described by time spent brushing the facial versus the lingual or occlusal surfaces. Caregiver verbal feedback was pulled from transcripts and analysed using content analysis. STROBE guidelines were used in reporting this study.

RESULTS

The two step residents most frequently completed or attempted were brushing their teeth (77% complete, 7% attempt) and rinsing their mouth (86% complete, 2% attempt). The average time spent brushing teeth was 60.33 s (SD = 35.15). In 66% of observed videos, toothbrushing occurred only on the facial tooth surfaces, with no time spent brushing the lingual or occlusal surfaces.

CONCLUSION

Caregivers are supporting residents to independently complete toothbrushing; however, the duration and quality of toothbrushing are not sufficient to ensure optimal oral health.

RELEVANCE TO CLINICAL PRACTICE

Clear, detailed guidelines are required to ensure adequate oral care for long-term care residents. Staff need to be aware that all surfaces should be brushed to ensure proper oral health.

Hand motor functions on the presence of red fluorescent dental biofilm in older community-dwelling Koreans

BACKGROUND

The Quantitative Light-induced Fluorescence-Digital (QLF-D) system visualizes old and mature dental biofilm as red fluorescence. Risk factors for poor oral hygiene have been identified, however, few studies have evaluated the relationship between mature dental biofilm and hand motor functions. This study aimed to investigate the effects of two important manual motor functions for object manipulation -handgrip strength and manual dexterity- on the presence of red fluorescent dental biofilm in older community-dwelling Koreans using QLF-D, an optical device that reveals dental biofilm.

METHODS

This cross-sectional study included 70 Korean participants aged ≥65 years, all of whom completed questionnaires and were tested for handgrip strength and manual dexterity. In total, 840 dental surfaces were photographed using QLF-D, and ΔR₂₀ values, which reflect mature dental biofilm accumulation, were calculated. The t-test was performed to analyze the differences in the ∆R₂₀ values according to sociodemographic characteristics, health-related characteristics and hand motor functions, while multiple linear regression analysis was used to investigate the effects of hand motor functions on the ∆R₂₀ values.

RESULTS

Multivariate regression analysis revealed that handgrip strength (β = -0.294) was the factor most strongly affecting mature dental biofilm accumulation (ΔR₂₀), followed by tooth-brushing time (β = -0.262) and manual dexterity (β = -0.241).

CONCLUSIONS

Reductions in handgrip strength and manual dexterity were independent risk factors for pathogenic dental biofilm accumulation. The results of this investigation suggest that programs designed to prevent the decline, as well as improve, handgrip strength and manual dexterity might improve the oral hygiene of older adults.

The association of medications with sedative properties with oral health behaviour in community-dwelling older people

OBJECTIVES

The objective of this study was to determine whether drugs with sedative properties are related to oral health behaviour-such as frequency of toothbrushing, using toothpaste and dental visits-and oral hygiene, measured by the number of teeth with dental plaque, among community-dwelling older people.

METHODS

The study population consisted of 159 community-dwelling, dentate, non-smoking, older people from the Oral Health GeMS study (Geriatric Multidisciplinary Strategy for the Good Care of Older People study). The data were collected by interviews and clinical examinations during 2004-2005. Sedative properties of drugs were assessed using the sedative load (SL) model. Logistic and Poisson regression models were used to estimate odds ratios/relative risks (OR/RR) and 95% confidence intervals (CI).

RESULTS

After adjusting for confounding factors, SL associated with infrequent toothbrushing (OR 1.72, CI: 0.61-4.89), toothpaste use less than twice a day (OR 3.34, CI: 1.39-8.12), non-regular dental visits (OR 2.28 CI: 0.91-5.30) and the number of teeth with dental plaque (RR 1.20 CI: 1.04-1.39) compared to participants without a SL.

CONCLUSIONS

The results of this study suggest that use of drugs with sedative properties indicates poor oral health behaviour among older people.

Oral health care-related beliefs among Finnish geriatric home care nurses

OBJECTIVES

The aim was to investigate beliefs about oral health care tasks among nursing staff caring for home-dwelling older people using the Nursing Dental Coping Beliefs (nursing DCBS) index.

METHODS

The study population comprised nursing staff working at the homes and sheltered accommodations of older people in Ylivieska, Finland (N = 141). The data were collected using the nursing DCBS index (five-point Likert scale).

RESULTS

On average, the nurses held moderate to high Oral health care beliefs, Internal locus of control beliefs and External locus of control beliefs, but low beliefs about Self-efficacy. The nurses with an earlier adjunct education scored lower for Oral health care beliefs on the factor Knowledge about preventing gum diseases (OR = 0.3, 95% CI: 0.1-0.9) than did the others. Regarding beliefs about External locus of control, the age group 31-49 years scored lower on the factor Retaining teeth as one ages (OR = 0.2, 95% CI: 0.1-0.7), but scored higher on the factor How to prevent dental diseases (OR = 5.6, 95% CI: 1.1-29.3) than did younger nurses (≤30 years). The nurses with only a nursing education showed significantly higher mean scores on the Self-efficacy factor Confidence of the need for dental knowledge than did those with an earlier adjunct education (P = 0.034).

CONCLUSIONS

The nursing staff mostly believed that oral diseases are preventable and teeth can be retained in advanced age, but failed to recognize the value of dental knowledge and had little confidence in their ability to manage oral diseases. Improving the oral health-related knowledge and self-efficacy beliefs of nursing staff will require additional oral health education.

Sedative load, carious teeth and infection in the periodontium among community-dwelling older people

OBJECTIVE

To study the relation of sedative load to carious teeth and periodontal pocketing - indication of infectious periodontal disease - among older people.

MATERIALS AND METHODS

This cross-sectional study was based on a subpopulation of 158 community-dwelling, dentate, non-smoking, 75-year-old or older people from the Oral Health Geriatric Multidisciplinary Strategy study. The data were collected by interviews and clinical oral examinations during 2004-2005. Sedative load was measured by means of the sedative load model, and Poisson multivariate regression models were used to estimate relative risk (RR) with 95% confidence intervals (CI).

RESULTS

Participants with a sedative load of either 1-2 (n = 31) or ≥3 (n = 12) had an increased likelihood of having carious teeth (RR: 1.8, CI: 1.2-2.6 and RR: 2.4, CI: 1.4-4.1, respectively) compared to participants without a sedative load. There was an inverse association between sedative load and the number of teeth with periodontal pockets.

CONCLUSIONS

Presence of dental caries was associated with the use of drugs with sedative properties. The use of drugs with sedative properties was not associated with the presence of periodontal pockets.
