Oral health of community-dwelling older Australian men: the Concord Health and Ageing in Men Project (CHAMP)

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.

Oral health-related quality of life of older Australian men

OBJECTIVES

The aims of this study were to assess oral health-related quality of life (OHRQoL) in a cohort of older Australian men and explore the association between their general health conditions, socio-demographic factors and OHRQoL.

METHODS

The Concord Health and Ageing in Men Project (CHAMP) is a cohort study of the health of a representative sample of Australian men, initiated in 2005-2006 with an initial sample of 1705 men 70 years or over. Participants completed a self-administered health and socio-demographic questionnaire and attended an interview and clinical assessment at baseline and each of three follow-up assessments. Information on oral health and responses to the Oral Health Impact Profile (OHIP-14) were collected in the 4th follow-up in which 778 men completed the OHIP-14 questionnaire and 614 men had a dental assessment. The prevalence of oral health impact was defined as a response of fairly often or very often to one or more of the OHIP-14 questions. Mean OHIP-14 scores were calculated for the 14 questions and used as the dependent variable in the regression analyses. Zero-inflated Poisson regression was used to estimate prevalence rate ratios (PRR).

RESULTS

Only 10% of men presented oral health impacts. In multivariate regression modelling, being born in Italy/Greece (PRR: 2.16, 95% CI: 1.93-2.42) or in other countries (PRR: 2.12, 95% CI: 1.89-2.38), having poor self-rated general health (PRR: 1.38, 95% CI: 1.24-1.53), having poor mental wellbeing (PRR: 1.14, 95% CI: 1.04-1.24), having ≥6 depressive symptoms (PRR: 1.18, 95% CI: 1.05-1.32), being a current smoker (PRR: 1.34, 95% CI: 1.06-1.70) and having more decayed tooth surfaces (PRR:1.01, 95% CI: 1.00-1.02) were associated with higher impact scores.

CONCLUSIONS

Overall, older Australian men exhibit good oral health-related quality of life. The inter-relationship between perceptions of general health and well-being, health and oral health variables and social background supports policy objectives of closer integration of general health and oral health services for older Australian men.

Does social support predict increased use of dental services in older men?

BACKGROUND

Past research on social support and dental visits in older people has been limited by cross-sectional design, limited social support dimensions and non-representative samples.

METHODS

Data came from men with natural teeth completing Waves 3 and 4 of the Concord Health and Ageing in Men Project in Sydney, Australia. The relationship between social support at Wave 3 (2011-2012) and at least one dental visit per year at Wave 4 (2014-2016) was examined by Poisson regression. Social support was measured by structural (marital status, living arrangements, family support and social interaction) and functional (social support satisfaction) domains.

RESULTS

About 673 men were analysed. Structural and functional social support were not associated with the pattern of usual dental visits 5 years later in univariable or multivariable analyses. The only consistent significant factor was income source, with older men who had other sources of income more likely to regularly visit the dentist than older men solely reliant on the pension for income (prevalence ratio: 1.31, 95% CI: 1.13-1.52).

CONCLUSIONS

We found no differences in the pattern of usual dental visits between older men with different levels and types of social support. For older Australian men, income source seems to be the most important determinant of regular dental visits. © 2022 Australian Dental Association.

Systematic Review of the Literature on Dental Caries and Periodontal Disease in Socio-Economically Disadvantaged Individuals

Dental caries and periodontal disease represent a health problem and a social cost for the entire population, and in particular for socio-economically disadvantaged individuals who are less resistant to disease. The aim of this review is to estimate the prevalence and severity of the two dental pathologies, caries and periodontal disease, in the different classes of socio-economically disadvantaged subjects and to understand which of them are most affected. A systematic search of the literature was performed in MEDLINE (via PubMed), EMBASE and Web of Science after establishing a suitable search strategy for each database, using keywords related to socio-economically vulnerable classes and health outcomes. Socio-economically disadvantaged individuals are more susceptible to tooth decay and periodontal disease (with relative tooth loss) than non-vulnerable people. Additionally, when multiple vulnerabilities are combined in the same subject, these oral diseases worsen. There is no type of vulnerability more affected by caries and periodontitis than others, since overall they all have severe disease indices. The data from this systematic literature review might be useful for health policy makers looking to allocate more resources and services to socially disadvantaged individuals, resulting in making them more resilient to oral disease due to their social marginalization.

Utilisation of Dental Services of Older People in Australia: An Economic Explanatory Model Based on Cost and Geographic Location

The increased percentage of older people retaining their natural dentition was associated with a burden of poor oral health and increased service demands. This study analyses the dental service utilisation of the ageing population in Australia and develops a modelled cost design that estimates the dental expenditure required to cover dental services for the aged population. Using the Australian Census of Population and Housing, ageing population and socioeconomic data were mapped to geographic boundaries and integrated with dental service provision data to estimate a model for the utilisation of dental services. The estimated financial cost of dental services was calculated based on the mean fees as per the Australian Dental Association's Dental Fees Survey. The utilisation of the services varied considerably across the states and also by type of service, with limited numbers using periodontic services. However, there was an increase in cost for replacement and restorative services (5020 million AUD), most evident in the socioeconomic deprivation areas. In addition, the average dental services utilisation cost increased noticeably in the lower socioeconomic deciles of all regions outside major cities. The geographic maldistribution of older people significantly affects the utilisation of dental services, especially among disadvantaged communities. A predicted cost model of 6385 million AUD would cover the oral health needs of older Australians.

Associations between the composition of functional tooth units and nutrient intake in older men: the Concord Health and Ageing in Men Project

OBJECTIVE

Inadequate nutrient intakes have been linked with poor dentition in older adults. The aim of this study was to investigate the associations between the composition of functional tooth units (FTU) and nutrient intakes in older men.

DESIGN

A cross-sectional study with a standardised validated diet history assessment and comprehensive oral health assessments. FTU were categorised by dentition type: (i) Group A (Natural FTU Only), (ii) Group B (Natural and Replaced FTU) and (iii) Group C (No Natural FTU). Attainment of nutrient reference values (NRV) for sixteen micronutrients was incorporated into a micronutrient risk variable, dichotomised 'good' (≥ 12) or 'poor' (≤ 11), and for seven macronutrients into a macronutrient risk variable, dichotomised 'good' (≥ 5) or 'poor' (≤ 4).

SETTING

Subjects selected from the local Sydney geographical areas.

PARTICIPANTS

Community-dwelling older men (n 608).

RESULTS

32 % (n 197) of participants were categorised as Group A, 27 % (n 167) as Group B and 40 % (n 244) as Group C. In adjusted logistic regression analysis, being in Group C, compared with Group A, was associated with intakes below NRV recommendations for fibre (OR: 2·30, 95 % CI 1·30, 4·05). Adjusted analysis also showed that men in Group C, compared with Group A, were more likely to have poor intake of macronutrients (OR: 2·00, 95 % CI 1·01, 3·94).

CONCLUSIONS

Our study shows statistically significant associations between the composition of FTU and poor macronutrient intakes. Maintaining natural pairs of occluding FTU may be important for attaining adequate nutrient intakes in older men.

Oral health status of newly admitted residents living in residential aged care

BACKGROUND

It is important to understand whether older people are admitted into residential care with existing dental diseases or their oral health deteriorates while residing in residential care. There is, however, little research available exploring the oral health status of people newly admitted into residential care. Understanding this disease trend would lead to effective prevention and treatment strategies to be trialled and implemented prior to admission. In this cross-sectional study, we hypothesize that older people with one or more natural teeth might have poor oral health prior to admission to residential care.

METHOD

The study was carried out using the de-identified oral health assessment database of an established domiciliary oral health care program in metropolitan New South Wales, Australia. Four hundred and nine participants with mean participant age of 85.56 years from 13 facilities from 2015 to 2018 fulfilled the inclusion criteria for this study.

CONCLUSION

This study confirmed that dentate, newly admitted residents to residential care had pre-existing dental problems and oral health concerns. Almost half of the newly admitted residents had an unsatisfactory oral cleanliness score when examined in their residential care setting.

Appetite, oral health and weight loss in community-dwelling older men: an observational study from the Concord Health and Ageing in Men Project (CHAMP)

Background

Unintended weight loss and the reduction in appetite are common phenomenon among older people. Reduced appetite has been linked to medication related reductions in saliva production, reduced taste ability and poor oral health. Poor appetite can result in reduced nutrient intake ensuing weight loss. It is possible that poor appetite is a mediating step on the causal pathway between oral health and weight loss. This study investigates whether poor oral health and loss of appetite are related to weight loss.

Methods

This is an observational study where data were obtained from the Concord Health and Ageing in Men Project (CHAMP). Information on socio-demographics, appetite and health related behavior was collected by self-completed questionnaire. Intraoral assessment was conducted by calibrated oral health therapists. Height and weight were measured by trained staff. Regression analysis investigated associations between oral health and appetite as risk factors for weight loss.

Results

Participants included 542 community dwelling older males. 99 older men (18.3%) experienced 5% or more weight loss over 3 years. Men who lost weight from baseline had lower BMI and lower body weight, had higher prevalence of frailty and depression, reported poorer appetite, and had fewer teeth (13.8 ± 9.5) than those who did not lose weight (16.3 ± 9.3). Before adjustment, the prevalence ratio (PR) for weight loss was 1.76 (95% Confidence Interval (CI), 1.19–2.59) for participants with 0–19 natural teeth present compared to those with 20 or more teeth. When adding appetite and other variables to the model, the PR for number of teeth and weight loss was unchanged: 1.78 (95% CI, 1.06–3.00). The mediation analysis showed that the indirect effect of appetite on the association between number of natural teeth on weight loss was not found to be significant.

Conclusion

This study found that number of natural teeth present and appetite are independently related to weight change among elderly men in Australia. Tooth loss can increase the risk of swallowing difficulty leading to change in food preference, avoidance of foods and a decrease in energy intake. Our study showed the importance of oral health interventions to encourage maintenance of 20 or more natural teeth in older people.

A Cross-Sectional Study of Perceived Dental Treatment Needs and Oral Health Status in Community-Dwelling Older Australian Men: The Concord Health and Ageing in Men Project

Background

Assessing perceived needs for dental treatment is important in understanding and predicting people's health behaviours. The purpose of this study is to examine older men's perceptions regarding dental treatment needs, and to investigate the disparity between perceived needs and the actual oral health of a population of community-dwelling older Australians.

Methods

Using cross-sectional data from the 4th wave of the Concord Health and Ageing in Men Project, logistic regression analysis of perceived needs for dental treatment was conducted for 596 men aged 78 and over, with functional tooth units (FTUs), number of decayed tooth surfaces, and periodontitis as independent variables.

Results

Thirty-six percent (n = 216) of the participants believed they required some form of dental treatment. The remaining participants did not perceive a need for treatment, yet 65.3% objectively required prosthodontic or restorative care. The regression model showed men with lower FTUs were significantly more likely to report a perceived need for dental treatment than those with 12 FTUs [0–6 FTUs: adjusted odds ratio (OR) 2.58, 95% CI 1.28–5.20; 7–11 FTUs: adjusted OR 2.43, 95% CI 1.16–5.10]. However, neither the number of decayed tooth surfaces nor the existence of periodontitis was associated with perceived dental treatment needs.

Conclusions

Most older men viewed their oral health positively, and the majority of those with objectively assessed needs, did not perceive themselves as requiring dental treatment. Loss of FTUs appears to alert participants to seek treatment, but not the presence of dental caries or periodontitis.

Oral health and cognitive status in the Concord Health and Ageing in Men Project: A cross-sectional study in community-dwelling older Australian men

BACKGROUND

Several studies have examined the relationship between cognition and oral health in older populations. To further understand this relationship, we examined the associations between cognitive function, chewing capacity and the number of teeth present in community-dwelling older males in Australia.

METHODS

Data were obtained from cross-sectional analysis of fourth wave of the Concord Health and Ageing in Men Project (CHAMP). Participants were 369 community-dwelling males aged 78 years or over. Cognitive function was measured utilising the Mini-Mental State Examination (MMSE). Chewing capacity was determined on ability to chew food items of different textures, and oral health data were collected. Ordinal regression was used to analyse associations between MMSE (four categories) and chewing capacity and number of natural teeth present.

RESULTS

Overall, 67.5% of participants reported that they could chew all 11 listed food items. Participants with fewer than 20 teeth were statistically significantly more likely to have cognitive impairment (unadjusted odds ratio (OR) 1.87; 95% confidence interval (CI) 1.25-2.79, adjusted OR 1.62; 95% CI 1.07-2.43). Participants with limited chewing capacity were also more likely to have cognitive impairment (unadjusted OR 1.91; 95% CI 1.25-2.94, adjusted OR 1.61; 95% CI 1.03-2.49).

CONCLUSIONS

This study suggests either that older men with fewer than 20 natural teeth and those with limited chewing capacity are more likely to have an associated cognitive impairment or that those with cognitive impairment are more likely to have fewer teeth and limited chewing capacity. Further longitudinal studies should clarify these relationships.

Associations between oral health and depressive symptoms: Findings from the Concord Health and Ageing in Men Project

OBJECTIVE

To investigate whether poorer oral health, tooth loss and lower usage of dental services are associated with depressive symptoms in older Australian men.

METHODS

Cross-sectional study of data collected from participants of the Concord Health and Ageing in Men Project. Depressive symptoms were evaluated by the Geriatric Depression Scale. Chewing capacity was estimated by ability to chew 11 food items.

RESULTS

The prevalence of depressive symptoms was 17.5%. Self-evaluated oral health, chewing capacity and the number of natural and decayed teeth were associated with depressive symptoms. After adjusting for multiple confounders, chewing capacity (PR 1.93; 95% CI 1.34-2.79) and decayed teeth (PR 1.68; 95% CI 1.03-2.75) maintained a significant association with depressive symptoms.

CONCLUSION

The direction of causality between oral health and depression is unclear; however, oral health may contribute to depression in older Australian men and depressive symptoms may limit chewing capacity and be aggravated by untreated dental decay.

Oral health behaviours of older Australian men: the Concord Health and Ageing in Men Project

BACKGROUND

The Concord Health and Ageing in Men Project (CHAMP) is a cohort study of the health of a representative sample of older Australian men. The aim of this paper is to describe the oral health behaviours and dental service use of CHAMP participants and explore associations between oral health behaviours with and general health status.

METHOD

Information collected related to socio-demographics, general health, oral health service-use and oral health behaviours. Key general health conditions were ascertained from the health questionnaire and included physical capacity and cognitive status.

RESULTS

Fifty-seven percent of the men reported visiting a dental provider at least once or more a year and 56.7% did so for a "dental check-up". Of those with some natural teeth, 59.3% claimed to brush their teeth at least twice or more a day. Most men (96%) used a standard fluoride toothpaste. Few participants used dental floss, tooth picks or mouth-rinses to supplement oral hygiene. Cognitive status and self-rated general health were associated with dental visiting patterns and toothbrushing behaviour.

CONCLUSIONS

Most older men in CHAMP perform favourable oral health behaviours. Smoking behaviour is associated with less favourable dental visiting patterns, and cognitive status with toothbrushing behaviour.

Oral health of community-dwelling older Australian men: the Concord Health and Ageing in Men Project (CHAMP)

BACKGROUND

The Concord Health and Ageing in Men Project (CHAMP) is a cohort study of the health of a representative sample of Australian men aged 70 years and older. The aim of this report is to describe the oral health of these men.

METHODS

Oral health was assessed when the men were all aged 78 years or older. Two calibrated examiners conducted a standardized intraoral assessment. Descriptive data were analysed by statistical association tests. Participants were excluded from the collection of some periodontal assessments if they had a medical contraindication.

RESULTS

Dental assessments of 614 participants revealed 90 (14.6%) were edentate. Men had a mean of 13.8 missing teeth and 10.3 filled teeth. Dentate participants had a mean of 1.1 teeth with active coronal decay. Those in the low-income group had a higher rate of decayed teeth and lower rate of filled teeth. Thirty-four participants (5.5%) had one or more dental implants, and 66.3% relied on substitute natural teeth for functional occlusion. Of those with full periodontal assessments; 90.9% had sites with pocket depths of 3 mm or more, 96.6% had sites with CAL of 5 mm or more, and 79.7% had three or more sites with GI scores of 2 or more.

CONCLUSIONS

There was a high prevalence of periodontal diseases and restorative burden of dentitions, which suggests that greater attention needs to be given to prevention and health maintenance in older Australian men.
