Recent Advances in Behavioral Research in Geriatric Dentistry1

This paper examines recent studies in behavioral science and health services aspects of geriatric dentistry. With the increased focus on special needs of older patients, researchers have become concerned with psychological and sociocultural factors that influence older people's oral health status, behavior, and attitudes. Studies of dental service utilization patterns among subgroups of the elderly, including those in long-term care settings, will be reviewed. Research on methods to improve oral health care behaviors will be discussed, with their implications for developing oral health promotion and service delivery programs. The special oral health needs of cognitively impaired and frail elderly will be reviewed. Studies of clinical decision-making in geriatric dentistry have been conducted. These studies have revealed significant gaps in dental professionals' knowledge and attention to the special needs of older patients. This and other aspects of behavioral research suggest the need for better methods to disseminate research findings in geriatric dentistry to clinical practice in this field. The presentation will discuss ways of improving dissemination and transfer of research findings to the clinical management of aged patients.     

Perceptions About Oral Health and Utilization of Oral Health Care Services Among Urban Finnish Elderly1

A representative sample of urban elderly living at home were studied for their perceived problems of oral health, treatment need felt for these problems, and their utilization of oral health care services. The majority of these elderly were denture wearers. Nearly all of the denture-wearing elderly had problems with their dentures, and about half of the dentate elderly had problems with their remaining teeth. The number of problems perceived increased with deteriorating health and decreasing income. Half of the elderly with denture problems and two-thirds of those who had problems with remaining teeth felt they needed dental treatment. Multivariate analyses found the number of perceived problems, having some natural teeth, and perceived general health to be the most important determinants of their perceived treatment need. Although two-thirds of the studied elderly felt no barriers to seeking treatment, only half of them had made their last dental visit less than five years ago. Having some teeth remaining, oral health education experiences, and income were found to be the best predictors of service utilization. Altogether, affective and cognitive factors rather than socio-demographic differences appeared to determine the elderly's perceptions about treatment need and their actual utilization of dental services, emphasizing the necessity of oral health education approaches designed for the elderly.     

Oral complaints and utilization of dental services in relation to general health factors in a 88-year-old Swedish population*

The aim of this study was to describe dental state, oral health problems, self-assessed ability to perform oral hygiene and utilization of oral health services in a sample of 88-year-old people (n=374) and to relate these variables to functional ability, subjective health and drug consumption. The intention was also to Identify barriers to utilization of dental care in non-institutionalized elderly people. The results of interviews showed that 46% of the subjects were dentate. Oral complaints were reported by 24% of the home living individuals. Poor health, medication and feelings of loneliness were factors associated with oral discomfort. Difficulties in performing oral hygiene activities were reported by 10% of the subjects and were correlated with functional impairments and feelings of loneliness. Utilization of dental services was correlated with dental state; 72% of the dentate and 8% of the edentulous subjects made regular dental visits. The main reason for not visiting a dentist was “no perceived need”. Independent of dental state, some factors were significantly correlated to low demand for dental services; these included feelings of loneliness, functional impairments and low school education.     

Assessing oral health promotion determinants in active Greek elderly

doi: 10.1111/j.1741‐2358.2011.00491.x
Assessing oral health promotion determinants in active Greek elderly Objective: To explore older adults’ patterns and risk behaviours to be invoked in the allocation of strategies to promote oral health. Background: Access to dental services is determined by factors that serve as barriers to or enablers of older adults’ behaviour and attitudes towards oral health. Appropriate oral health promotion activities are of particular importance among the elderly in altering oral health behaviour through education, prevention and health protection. Methods: A cross‐sectional study was conducted among 108 dentate elderly subjects. They were attending a University Prosthetic Dentistry Clinic in Greece as patients seeking treatment. Participants underwent a clinical examination and an interview. Results: Data extracted revealed that cost and no disease awareness were the most frequently mentioned barriers to regular dental visits. Most of the participants presented low level of income and education and reduced presence of adverse dental health symptoms compared with the actual oral health status. Besides some predisposing factors, enabling and need variables significantly affected access to dental care services, participants’ number of remaining teeth and as a consequence oral health status. Conclusion: Profiling older adults’ demographics, economic, social and cultural status and their attitudes and beliefs could further contribute in developing universal activities and strategies for oral health promotion so as ageing challenges are favoured.     

Comparing Older Adults' Perceived Need for Dental Care with a Normative Hierarchy of Needs1

The elderly are reported to have poor perception of their need for dental care. In a secondary analysis of data from a community interview and clinical examination survey of older adults, we set out to determine the nature and extent of the inconsistency of perceived and normative needs. The data were gathered originally to estimate the oral health status and need for treatment among adults aged 50 and older in East York, Ontario. In the interview, participants responded to four questions dealing with their satisfaction with, and need for, dental care. Dentists conducted clinical examinations following WHO methods which included oral health status and treatment needs. Data were analyzed using SPSSPC +. We placed the clinical needs in order from urgent to no need, following ADA guidelines. The perceptions of subjects were then compared to this normative hierarchy using Kruskal-Wallis analysis of variance. We found that participants' perceptions were closely associated with the normative hierarchy in all comparisons. Our results suggest that the concordance between perceived and normative needs is greater than previously reported.     

Measuring psychosocial variables that predict older persons’oral health behaviour

The importance of recognising psychosocial characteristics of older people that influence their oral health behaviours and the potential success of dental procedures is discussed. Three variables and instruments developed and tested by the author and colleagues are presented. A measure of perceived importance of oral health behaviours has been found to be a significant predictor of dental service utilization in three studies. Self-efficacy regarding oral health has been found to be lower than self-efficacy regarding general health and medication use among older adults, especially among non-Western ethnic minorities. The significance of self-efficacy for predicting changes in caries and periodontal disease is described. Finally, a measure of expectations regarding specific dental procedures has been used with older people undergoing implant therapy. Studies with this instrument reveal that patients have concerns about the procedure far different than those focused on by dental providers. All three instruments can be used in clinical practice as a means of understanding patients’values, perceived oral health abilities, and expectations from dental care. These instruments can enhance dentist-patient rapport and improve the chances of successful dental outcomes for older patients.     

Oral health and access to dental care: a qualitative investigation among older people in the community

doi:10.1111/j.1741‐2358.2009.00320.x
Oral health and access to dental care: a qualitative investigation among older people in the community Objective: The aim of this study was to explore older persons’ beliefs and attitudes towards oral health and access to and use of dental care services. Background: As the proportion of dentate older people increases, the need and demand for dental services will rise (J Public Health Dent, 60, 2000, 276). Design: Focus groups and semi‐structured interviews were used for data collection. Setting and subjects: The study participants included 63 older people in Perth, WA. Results: Five major themes emerged from the interviews – the need for information and knowledge; accessibility of services; cost and affordability of oral care; fear and anxiety regarding dental visits and relationships with dentists. Attitudes and behaviours were slow to change in this group. Conclusion: This investigation provided important perspectives regarding oral health and dental access for older people residing in the community and demonstrated the importance of understanding this group when considering provision and use of services.     

Oral disease experience of older adults seeking oral health services

doi:10.1111/j.1741‐2358.2009.00311.x
Oral disease experience of older adults seeking oral health services Objective: The objective of this investigation was to describe the dental disease (dental caries and alveolar bone loss) experience in a sample of community‐dwelling older adults who regularly utilize dental services in New York City. Background: Public financing for dental care directed at older adults in the United States is minimal. Improved preventive methods, primarily the use of fluorides, have resulted in declines in tooth loss, and concomitant increase in risk for dental diseases among older adults. While the oral disease burden in institutionalized elderly and those unable to access services is well‐documented, the dental care needs of older adults who access dental services are not well documented. Materials and Methods: Radiographic and record review were used to determine prevalence of dental caries, alveolar bone loss, frequency of service utilization, and medical status in this cross‐sectional investigation of a sample of older adults (N = 200) using dental services at Columbia University College of Dental Medicine. Results: Only 9% of the sample was completely edentulous, the mean DMFT was 19.9 and mean alveolar bone loss was 3.6 mm. Missing and Decayed Teeth accounted for 57.8% and 6.5% of the total caries burden respectively. Missing Teeth and alveolar bone loss increased with increasing age, but there was no increase in Decayed Teeth. Conclusions: While access to and utilization of dental services may result in improved tooth retention, older adults who use dental services continue to have dental care needs, especially periodontal care needs.     

Challenges and barriers to quality oral care as perceived by caregivers in long-stay institutions in Brazil

doi: 10.1111/j.1741‐2358.2011.00475.x
Challenges and barriers to quality oral care as perceived by caregivers in long‐stay institutions in Brazil Objective: To describe how caregivers perceive the oral health status in the elderly they care for; the routines for oral hygiene in nursing homes; caregivers perceived barriers for quality oral care; and the caregivers competence and need for training in this area. Background: The phenomena surrounding ageing has been the subject of worldwide interest, particularly concerning issues related to institutionalised elderly, where several studies have shown the precarious oral health status of such individuals. Materials and methods: A qualitative interview study was held in a city in southern Brazil. Study participants were 26 caregivers of elderly people, belonging to seven institutions. Statements were collected through interviews, whose results were interpreted by phenomenological analysis. Results: Caregivers of institutionalised elderly reveal contradictions in knowledge and practices of oral health. Although it could be expected that the perception and attitudes of caregivers of their own oral health could influence the care they offer to the elderly, barriers to the implementation of such activities appear to refer to situations outside of their responsibility, especially in the absence of time and staff. Conclusions: The oral care of older people in geriatric institutions requires multidisciplinary and interinstitutional actions capable of reversing the continuing framework of neglect, requiring interventions for health promotion and disease prevention that can and should be implemented in institutions.     

Utilization of dental health services by community-dwelling older adults in Japan who attended a weekly educational programme

Objectives: The purpose of this study was to describe dental health services utilization and identify factors which influenced a group of independently living elderly persons in an urban area of Japan. Subjects: The study sample consisted of 2,990 participants, 83% of the total sample of the Senior Citizen's College, who were 60 years and over. Measurements: Their dental utilization and satisfaction with dental treatment were measured by a questionnaire from 1993 to 1998 Results: The mean age of the subjects was 66.5 years and 52% were male. Sixty percent of the subjects had visited a dentist within the previous year, and 33% of them had received a regular oral health check‐up. The majority of the subjects (63%) were satisfied with their dental treatment. A multiple stepwise logistic regression analysis showed that dental services utilization had a significant positive association with presence of teeth (p<0.001), being male (p<0.01) and satisfaction with financial status (p<0.05). A regular oral health check‐ups had a significant association with presence of teeth (p<0.001), satisfaction with financial status (p<0.05) and aging (p=0.001). Conclusions: Dental health services utilization was related to the presence of teeth and financial status, rather than age or medical conditions, among independently living elderly persons in an urban area of Japan.     

Informing the debate on oral health care for older people: a qualitative study of older people’s views on oral health and oral health care

doi: 10.1111/j.1741‐2358.2009.00274.x
Informing the debate on oral health care for older people: a qualitative study of older people’s views on oral health and oral health care Background: Older people represent a growing and diverse section of the population. As age increases, people are more likely to experience health and mobility problems and be at higher risk of developing oral disease. Nevertheless, few older people utilise primary oral healthcare services. It is therefore important to understand the value older people place on oral health and dental services to inform providers and planners of oral health care. This research was conducted as part of a study to identify potential ways of minimising barriers to oral health care in older people. Objectives: To explore perceptions of oral health and oral healthcare services amongst older people living in a socially deprived inner city area and how these are related to service utilisation. Methods: A qualitative approach was utilised to explore the range of issues related to older people’s perceptions of oral health and their views on health care. This involved a combination of focus groups and semi‐structured individual interviews with older people and their carers. Data analysis was conducted using the Framework approach. Results:

• ? Response: Thirty‐nine older people and/or their carers participated in focus groups.
• ? Oral health perception: Oral health was associated with the presence of natural teeth, the absence of pain, practical/social functioning, preferably supported by positive assessment by a dentist.
• ? Oral health life‐course: Older people have a long and complex dental history. Past negative experiences with oral health care, especially in childhood, strongly influenced present attitudes towards dentistry and dental personnel.
• ? Citizenship and right to health care: There was a strong perception that, as ‘British citizens’, older people should have a right to free health care and that the National Health Service (NHS) should support them in this phase of their life.

Conclusions: The oral health life‐course of older people is an important influence on their perceptions of oral health and dental attendance. They consider oral health of importance and place great emphasis on their citizenship and rights of access to state funded oral health care. This raises important issues for the funding and delivery of NHS oral health care for older people.     

Geriatric dentistry--meet the need

Geriatric dentistry or gerodontics is the delivery of dental care to older adults involving the diagnosis, prevention, and treatment of problems associated with normal ageing and age-related diseases as part of an inter-disciplinary team with other health care professionals. Geriatric health is an ignored and under-explored area worldwide. Oral health reflects overall well being for the elderly population. Conversely, elderly patients are more predisposed to oral conditions due to age-related systemic diseases and functional changes. The major barriers to practising geriatric dentistry are the lack of trained faculty members, a crowded curriculum and monetary concerns. For successful treatment, the practitioner must adopt a humanitarian approach and develop a better understanding of the feelings and attitudes of the elderly. Prevention and early intervention strategies must be formulated to reduce the risk of oral diseases in this population. In future, dental professionals must have a proper understanding of the magnitude of the services to be provided to the elderly. This could only be realised through an education programme in geriatric dentistry, which should be started without further delay. This article hence sets out the objectives, needs, present scenario, strategies and types of dental treatment required by the elderly population.     

The prosthetic need WHO index: a comparison between self‐perception and professional assessment in an elderly population

The purpose of this study was to consider the criteria for establishing the need for prosthesis, by comparing the need perceived subjectively by a patient (self‐perception) with that assessed by an examiner according to the WHO diagnosis criteria. The proposed domiciliary sample comprised 270 elderly (aged 60 years or older) residents in a municipality in southern Brazil. The interviews and oral examinations were conducted by two dentists following a period of training and calibration. The criteria used conformed to the WHO and FDI standards. Statistical treatment of data included bivariate and multivariate analysis using SPSS 10.0. Only five patients identified the need for a prosthesis when not identified by the examiner. In the case of 172 elderly subjects, there was agreement in the self‐perceived and observed treatment needs. The need for prosthesis was found in 93 elderly subjects who did not perceive any need for prosthetic treatment. The multivariate analysis showed that the variables age, gender, residential area and form of service most sought after during their lives were significantly associated with a better self‐perception of oral health. The professional criteria based on WHO guidelines differed from the self‐perceived need. Elderly male subjects who lived in a rural area and were 70 years of age or more, who did not participate in third age groups, and who had not sought dental services for most of their lives were the least likely to perceive the need for prosthetic treatment, thereby underestimating their oral health needs.     

Validation of a Sinhalese translation of the Oral Health Impact Profile-14 for use with older adults

Objective : To test the psychometric properties of a Sinhalese translation of the OHIP‐14 scale for use among older adults in Sri Lanka. Design : A cross‐sectional survey. The English version of the OHIP‐14 was translated in to Sinhalese, pre‐tested and subsequently administered to the subjects by a trained interviewer. Setting : Moratuwa — a densely populated urban area in the Western province of Sri Lanka. Subjects: 585 individuals aged 60 years and above. Main outcome measures : Reliability of the translated scale was assessed in terms of internal consistency using Cronbach's alpha. Construct validity was evaluated by examining the associations between perceived oral health status, perceived need for dental care and the OHIP scores. Results : Cronbach's alpha of the translated scale was 0.93. Corrected item‐total correlation coefficients ranged from 0.53–0.80. The highly significant associations between perceived oral health status, perceived need for dental care and the OHIP scores support the construct validity of the translated scale. Conclusion : The Sinhalese translation of the OHIP‐14 is a valid and reliable instrument to measure oral health related quality of life in older adults of Sri Lanka.     

Dental Status in the Elderly: A Review of the Swedish Literature1

1. Elderly persons living in their own homes have over the past 20 years tended to retain an increased number of natural teeth. This tendency is confirmed especially in the ongoing studies by Tor Österberg, nr 12 and 13. These studies indicate a decreasing edentulous part of the 70-year old cohorts from 1971, 1976 and 1981. 2. Elderly persons dependent on institutional care are edentulous in as high degree today as 20 years ago. According to this criterion, therefore, their dental health has not improved. 3. Dentures worn by elderly persons frequently are defective in fit and function. For the general wellbeing and health in later life, mastication of a well-balanced diet and lack of discomfort from denture-bearing mucosal surfaces are important. Information in this respect and measures to improve masticating function are greatly needed among persons in the higher age groups, whether living at home or in institutional care. 4. Caries activity is increasing among elderly persons. 5. Periodontitis (loosening of the teeth) is very frequently found in elderly persons. 6. Oral hygiene requires improvement. 7. Among the elderly, living in their own homes or in institutions, the need for odontologic care is objectively great, but the demands currently made are remarkably low. 8. Of the aged in institutional care, about 75 per cent are suitable for measures of oral care. A change in dental health seems to be slowly taking place among the elderly, in that increasing numbers keep more of their own teeth longer in life. The demands made by the high age groups on the odontologic services, though increasing, are still very low relative to the objective and consequently great accumulated needs. This contrast is especially pronounced among geriatric patients in institutions. An aggressive, searching approach to both restorative and preventive oral care in the higher age groups is of pressing importance if optimum conditions for eating and chewing late in life are to be achieved. For timely counteraction of the tendency to a more passive attitude t o dental care that commonly accompanies rising age, information on these matters should be energetically disseminated among persons due for retirement or new-l y retired.     

Factors associated with oral health perception in older Brazilians

Objectives: To investigate the self‐perception of oral health in older people, aged 65–74, from the central region of southern Brazil. Methods: Cross‐sectional population‐based study using data from the Oral Health Conditions Survey of Southern Brazil, developed between the years 2002 and 2003, by the State Health Secretary (SHS) of Rio Grande do Sul (RS), Brazil. Socioeconomic and demographic variables, self‐perception of oral health and clinical data, as well as dental pain were evaluated in 618 elderly people. Multinomial logistic regression was used to evaluate the effect of explanatory variables on the self‐perception of oral health. Results: Almost half of the elderly were edentate and rated their oral health as good or very good. With regard to dental pain, 28.8% of the people declared that they had experienced dental pain in the 6 months before the interview. There was a significant relationship between dental pain and classification of oral health, and chewing ability. Following adjustment, the need for dental prostheses remained associated with the influence of oral health on establishing relationships. Similarly, personal income remained associated with the elderly's perception of their ability to talk. Finally, the level of education remained related to the influence of oral health status in people's relationships. Conclusion: Dental pain and the need for dental prostheses were the main factors that affected the self‐perception of oral health of elderly people from southern Brazil.     

Relationships between higher‐level functional capacity and dental health behaviors in community‐dwelling older adults

doi: 10.1111/j.1741‐2358.2012.00654.x Relationships between higher‐level functional capacity and dental health behaviors in community‐dwelling older adults Objective: The aim of the present study was to elucidate relationships between higher‐level functional capacity and dental health behaviours in community‐dwelling older adults. Background: In ageing society, it is necessary to promote oral health in the elderly, because good oral health is a significant contributing factor to good general health. Higher‐level functional capacity has been considered a crucial factor for successful independent living in the elderly. We hypothesised that functional capacity is a significant indicator of dental health behaviours. Methods: Three hundred and thirty‐eight adults aged 65 years or older were enrolled in this study. Higher‐level functional capacity was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG‐index). Univariate and multivariate models were constructed with dental health behaviours, such as regular visits to a dentist, brushing frequency and use of extra cleaning devices, as the dependent variable, and the total TMIG‐index score and its subcategory scores as the principal independent variable. Results: Univariate logistic regression analysis demonstrated a significant correlation between low TMIG‐index and ‘intellectual activity’ subcategory scores to lack of regular visits to a dentist and not using extra cleaning devices. Using a multivariate model, significant relationships remained after adjusting for a number of variables including demographics, medical status, lifestyle and number of remaining teeth. Conclusion: Intellectual activity of higher‐level functional capacity may be an accurate indicator of dental health behaviours in community‐dwelling older adults. Intellectual activity should be taken into consideration to effectively promote oral health behaviours and oral hygiene in elderly persons living independently.     

Oral health and dental care facilities in Maltese residential homes

Objectives: To establish oral health care practices, including the use of dental services, in the residential homes of Malta and Gozo by assessing the knowledge of home managers and assistance of care staff regarding residents’ oral health and hygiene; and evaluating the residents’ demand for dental treatment and residential home managers response to this demand. Subjects: A total population sample of licensed residential homes (38) in Malta and Gozo was used comprising all home managers in government (seven), church (20), and privately run (11) residential homes. Method: A 19‐question questionnaire was designed, piloted and sent to the home managers requesting them to report on the dental care provision for their elderly residents. The questionnaire was distributed by post, along with a reply‐paid envelope and an explanatory letter. A response deadline of 1 month was included. Results: An 87% response rate was achieved. Whilst the majority of home managers (64%) were aware of domiciliary dental services, there was no code of care practice for oral health. Routine dental check‐ups were not organised for residents of most homes. Although home staffs were generally given information about residents’ oral health and hygiene, the majority did not assist residents with oral hygiene. Home managers identified the following barriers to the use of dental services by residents: cost, communication problems with dental staff, journey to place of treatment, waiting time at the dental clinic, access to premises/clinic, lack of information on oral health and dental service availability, no one to accompany the person to the clinic, and health problems such as mobility, poor eyesight, hearing impairment and mental health status. Conclusion: Although most home managers appreciate the importance of oral health care for their residents, the residents still face many barriers to maintaining adequate oral health care and accessing dental services.     

Assessing expressed need and satisfaction in complete denture wearers

Objectives: The need to assess both lay and professional views of oral health is believed to be at the centre of success when providing dental health care for older patients. Self‐perceived physical (oral) health and perceptions of psychosocial functioning must be included if expressed need is to be assessed. The aim of this work was to construct an expressed need schedule and to assess the ability of this assessment to predict older community‐based patients' satisfaction with complete dentures. Design: Survey of 260 people aged 65 years and over. Setting: Community setting. Main outcome measures: The participants were interviewed using a 55 item modified version of the Oral Health Impact Profile (OHIP) to assess their psychological, social and perceptions of their oral health. All participants were subjected to an oral examination. Results: The results showed that complete denture wearers compared had greater experience of difficulties associated with oral health and psychological functioning. Factor analysis allowed the identification of three dimensions associated with psychological, social and self‐perceived physical (oral) health. When these factors were regressed with normative denture treatment need against satisfaction with complete dentures, satisfaction was characterised by high self‐perceived physical (oral) health, low social health problems and no identifiable normative need. Conclusion: This work supports the inclusion of self‐perceived physical (oral) health and psychosocial health (expressed need) questions in a schedule when predicting satisfaction with complete dentures.
