Dental Care for the Elderly

The geriatric population in many parts of the United States is underserved by dentistry. Socioeconomic problems, difficult access to dental facilities, and confusion about the need for dental care often prevent the elderly from seeking dental service. Because dental diseases are not life threatening or outwardly disabling, administrators of institutions for the elderly and health legislators place a low priority on dental care for the elderly. These factors working in concert with the insidious, progressive, and cummulative nature of denture diseases contribute to the poor dental health experienced by some segments of the geriatric population. Dentistry has the manpower and the technology to improve the oral health of the elderly, but society must be made aware of the importance of dental health in the total health of elderly persons in order that dentistry be given a chance to achieve that goal.     

Estimates of time and propensity for dental treatment among institutionalised elders

The oral health and concerns of elderly residents were surveyed in a stratified random selection of 41 long-term care facilities in Vancouver. The residents who could participate were examined and interviewed to determine their oral health and concerns about dental treatment. The need and time required for treatment were estimated in six groups to reflect the propensity for treatment in dentate and edentate subjects. The propensity for treatment was high in about one-third of the participants whereas it was unlikely that one-tenth of those examined would ever use a dental service. In general, there was a widespread need for a diagnostic service because so few had been examined by a dentist in the previous year. Prosthodontics accounted for most of the treatment in all of the propensity groups, with substantially more time required by the dentate residents. There was also a substantial need for management of mucosal pathoses and oral hygiene and, to a lesser extent, for dental restorations and endodontics. Overall, our estimates indicate a substantial need for dental treatment among residents of long-term care facilities, although the need is reduced by half if the propensity for treatment is considered.     

Evaluation of an oral function promotion programme for the independent elderly in Japan

Objectives: The purpose of this study was to provide an oral function promotion programme for the independent elderly and evaluate the changes in oral health status and oral function. Background: Few studies have scientifically analysed and evaluated the effectiveness of oral function promotion programmes provided for the independent elderly. Materials and methods: The subjects were independent elderly females (mean age: 74.6 ± 6.3) recruited from senior citizens’ centres in Tokyo. The intervention group (n = 79) received a 3‐month oral function promotion programme, which included facial muscle and tongue exercises and salivary gland massages. The control group (n = 62) did not receive this programme. Results: In the intervention group, the tongue coating scores decreased and the organoleptic score of oral malodour fell. The amount of food debris in the oral cavity decreased and the tongue dryness improved. Furthermore, the salivary flow rate increased. The length of time for maintaining the tongue in the forward position increased from 11.2 s to 18.7 s, and the number of times for moving the tip of the tongue in a clockwise circular motion, counter‐clockwise circular motion and side‐to‐side motion within 30 s, increased from 14.5 to 20.6, 14.5 to 20.2, and 17.2 to 23.3 respectively. The number of times for movement of the lips significantly improved from 23.0 to 28.8 and the pronunciation of words was observed to be clearer. Conclusion: An oral function promotion programme was effective in improving the oral health status and oral function of an independent elderly population.     

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.     

Discussions on oral health care among elderly Chinese immigrants in Melbourne and Vancouver

doi: 10.1111/j.1741‐2358.2011.00568.x Discussions on oral health care among elderly Chinese immigrants in Melbourne and Vancouver Background: This study explored how elderly Chinese immigrants value and relate to how acculturation influences oral health and subsequent service use. Methods: Elders who had immigrated to Melbourne and Vancouver within the previous 15 years were recruited from local community centres and assigned to focus groups of 5–7 participants in Vancouver (4 groups) or Melbourne (5 groups). Results: Following an iterative process of thematic analysis, the discussions revealed that immigrants care about the comfort and appearance of their teeth, and they value Western dentistry as a supplement to traditional remedies, but they have difficulty getting culturally sensitive information about oral health care. Accessing dentistry, they explained, is distressing because of language problems and financial costs that impose on their children. Consequently, many immigrants obtain dental treatment in China when they return for occasional visits. They felt that separation of dentistry from national health care programmes in Canada and Australia disregards natural links between oral health and general health. Conclusions: The similarity of concerns in both cities suggests that dissemination of information and availability of services are the important themes influencing oral health, and that, beliefs developed over a lifetime play an important role in interpreting oral health in the host country.     

The Epidemiology of Dental Diseases in the Elderly1

This paper summarizes and evaluates epidemiologic evidence on adult dental conditions with a focus on older adults. Information is presented on coronal caries; root caries; loss of teeth, attrition, abrasion, and erosion; periodontal diseases; and oral cancer. The author concludes that the oral health status of the elderly in the United States is essentially unknown. There are no recent, representative population base studies of oral conditions in the elderly. Studies of prevalence or incidence of oral diseases typically include few elderly persons or describe a select group of elderly who are at high risk. Furthermore, it is not really known whether the incidence and prevalence of coronal caries or root caries is actually increasing or is part of a cohort effect. While oral cancers have been shown to increase with age, there is no information as to whether their incidence rates are increasing. While, clinically, there are indications that attrition, abrasion and erosion are characteristics that are more likely to be seen in older adults, there is no information about their distribution in the population. There is evidence that loss of teeth is decreasing but nothing is known about the patterning of that loss. As for periodontal diseases, much work is needed to identify various syndromes that may be distinguished by their distribution in the population as well as determining whether periodontitis is a condition responsible for a majority of tooth loss or just the majority of tooth loss in a small high risk group. In addition, some suggestions are presented for future directions of research in this area.     

Geriatric dentistry: is rethinking still required? A community‐based survey in Indian population

Gerodontology 2012; doi: 10.1111/j.1741‐2358.2012.00667.x Geriatric dentistry: is rethinking still required? A community‐based survey in Indian population Background: India has a large geriatric population (60 years and above) of 77 million; comprising 7.7% of its total population. Poor oral health and loss of teeth not only adversely affect the dietary intake and nutritional status and thereby compromise general health, but can also deny them the pleasure of eating food of their choice. Objective: To assess the level of edentulousness, denture wearing and denture needs of the elderly in the community and to study the correlation between oral health parameters and sociodemographic variables which would help us to define better treatment modalities, counselling and thus improve the oral health of our geriatric patients. Materials and Methods: Subjects who were 60 years and above were considered for this study and were randomly selected. Of the 1360 elderly who were enrolled in the study, 780 (57.35%) were males and 580 (42.64%) were female. This sample size is in proportion to the total population for the pilot study. They were given an oral examination and a questionnaire. Results: Fifty seven percent (57%) of the elderly were not satisfied with their oral health status and function. Conclusion: Complete edentulousness of both the arches was highest in the middle socio‐economic group, and was the lowest in the low socio‐economic group. Less than 50% of edentulous elderly and only 10% of partially edentulous elderly were wearing dentures.     

Development of oral home telecare programme for the home-dwelling elderly: a pilot study

Objectives: The aim of the pilot study was to develop and evaluate a telecare programme for home‐dwelling elderly to provide education on oral and general health care. Design: A field trial with a computer system linking a university with a structured network. Subjects: A group of home‐dwelling elderly males with a mean age of 73.3 years. Methods: Qualitative assessment following videophone interviews with clients and their families. Results: Clients and families were able to gain a better understanding and knowledge of oral health care particularly the skills required to perform new oral care procedures. Conclusions: Preventive oral homecare via videophone offers the potential for providing a long‐term structure for maintaining oral health particularly with limited social resources.     

Assessing the state of the art in national ocean policy studies

Abstract

For over a decade the nation‐states of the world have been redefining the legal and political status of the world's oceans, both unilaterally and in multilateral negotiations. Despite the growing importance of ocean policy, we know too little concerning what are current nation‐state marine interests, how they make their marine related decisions, or how they organize themselves for marine policy. This paper was written as an organizing paper for a workshop to assess the state of the art in national ocean policy studies. It was sponsored by the Marine Science Affairs Program, International Decade of Ocean Exploration Office, National Science Foundation. The paper states the goal of the workshop, it defines the terms of reference, such as public policy, public policy analysis, comparative public policy analysis and national ocean policy; it offers a “systems”; influenced model for the evaluation of national ocean policy, and it identifies the state of our knowledge of the various components of national ocean policy by performing a computer‐based survey of the literature. Some 5,000 studies were examined and reduced to 1,000 relevant items. Highlights of the findings show that: 1) we know most about the output stage of ocean policy, less about input, little about process; 2) we know most about bureaucratic ocean decisions, less about legislative, little about judicial ocean decisions; 3) output studies rose and declined, input studies have increased steadily, and process studies may show a sharp rise; 4) we know most about the United States, Japan, and the USSR, less about Western Europe, little about the Third World; and 5) most of the studies were conducted by those using “traditional”; research tools.     

The English national risk-reduction programme for preservation of sight in diabetes

This paper discusses the new national guidelines for a systematic screening programme to detect sight-threatening diabetic retinopathy in the population of people with diabetes in England. A review of the literature examines the evidence base to support screening interventions and effective management and treatments in diabetic retinopathy. The current evidence supports the establishment of a digital retinal photography system using pupil dilation. A Policy Advisory Group has been formulated by the National Screening Committee to guide the meeting of this target in England. A conclusion is made that with increased effort and organisation, health care professionals can ensure that the screening programme is successfully implemented and rates of visual impairment and blindness caused by diabetic retinopathy can be reduced significantly.     

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 health of the elderly living in residential homes in Slovenia

doi: 10.1111/j.1741‐2358.2011.00497.x
Oral health of the elderly living in residential homes in Slovenia Objectives:  To evaluate oral health status of the elderly, living in eight randomly selected residential homes for senior citizens across the country. Background: The percentage of the elderly is growing worldwide. With ageing, risks of various oral diseases, including dental caries and periodontal disease, are growing. Methods: Altogether 296 elderly people (88 men, 208 women) of average age 79.89 ± 7.4 years were questioned about their medical condition and oral health practice and examined orally. Evaluation of clinical examination was carried out by DMFT, plaque index ( 10 ) and Community Periodontal Index of Treatment Need (CPITN). Results: Of 296 participants, 106 (35.8%) were edentulous, 95 (32.1%) had one to nine teeth and 95 persons (32.1%) had 10 or more teeth. The average number of teeth in an individual was small: 6.76 ± 7.47. The average number of teeth with caries lesions was 3.59 ± 4.70, filled teeth 1.94 ± 3.63 and teeth without caries or fillings 1.19 ± 2.41. The average DMFT value was 30.75. In 69.5% of participants, dental plaque was visible with the naked eye. Of 171 subjects, in whom CPITN index was appraised, 81.9% would need oral hygiene education, 56.7% would need scaling and root planning and 21.6% would need periodontal surgical treatment. Conclusions: The results of this study indicate poor oral health of the elderly living in residential homes situated in different towns in Slovenia. It is of utmost importance to highlight the necessity of improving oral health care of this population.     

A review of the effectiveness of oral health promotion activities among elderly people

Objectives: This study aimed to review the effectiveness of oral health promotion studies conducted among elderly people between 1997 and 2007. Methods: Four electronic databases were searched and papers were rated for level of evidence and scientific quality. Key findings of the papers were summarised. Results: Thirteen thousand nine hundred and four papers were retrieved and 17 studies (18 papers) met the criteria for the review: 13 were randomised controlled studies, three were quasi‐experimental studies and one was a pre‐/post‐single group intervention study. According to the Levels of Evidence, 11 studies could be categorised as 1b and six studies could be categorised as 2b. The quality of the evidence of the 17 studies ranged from 12 to 19; 13 of the studies had a score of 15 or above; four of the studies ranged from 12 to 14. Evidence from oral health promotion activities aimed at preventing caries, improving periodontal health and altering oral health behaviours were reviewed. The use of fluoride, antimicrobial agents and health‐care provider education has important roles within oral health promotion activities for elderly people. Studies have tended to be of short‐term duration and rely on surrogate outcome measures of oral health. Conclusion: In the last 10 years, increasing attention has been paid to oral health promotion activities among the elderly population and high quality evidence has emerged. However, there is a need for even higher‐quality research to provide more definitive guidelines on oral health promotion practices for elderly people.     

Oral health‐related quality of life and nutritional status of institutionalized elderly population aged 60 years and above in Mysore City,India

doi: 10.1111/j.1741‐2358.2012.00651.x Oral health‐related quality of life and nutritional status of institutionalized elderly population aged 60 years and above in Mysore City, India Objective: To assess whether oral health–related quality of life (OHRQoL) is associated with nutritional status in the institutionalised elderly population of Mysore. Background: Malnutrition in the elderly has an evident impact on their general health and quality of life. Analysis of data of the Geriatric Oral Health Assessment Index (GOHAI) and their association with the Mini Nutritional Assessment (MNA) results improves our understanding of the complex relationship between oral health and malnutrition. Materials and methods: The study was conducted among the institutionalised elderly population in Mysore city, Karnataka. Data on socio‐demographic, oral health status were gathered. OHRQoL was evaluated using GOHAI, and malnutrition risk using MNA. Results: Out of 141 elderly, 41.1% were men and 58.9% were women with mean age of 72.2 ± 7.5 years. Mean GOHAI score was 47.03 ± 9.2, with 69.5% had low perception of oral health. Mean MNA score was 9.91 ± 2.4, 15.6% were malnourished, 52.5% were at risk of malnutrition and 31.9% were adequately nourished. A strong association was found between the mean GOHAI and MNA scores. Conclusion: Oral health–related quality of life was associated with nutritional deficit, and it requires a greater integration between dentistry and nutrition in the health promotion of older adults.     

Oral health among institutionalised elderly in Zagreb, Croatia

Objective: A survey of dental health status was conducted in the institutionalised elderly in Zagreb, Croatia in order to assess the dental and oral health of the elderly population. Participants: In 139 institutionalised elderly from a single nursing home in Zagreb, dental and oral status was registered according to World Health Organization criteria. There were 108 (77.7%) female and 31 (22.3%) male subjects aged 58–99 years. Results: The results showed that 45.3% of the interviewed persons were totally edentulous in both jaws. A significant increase in prevalence of edentulousness with the increasing age was recorded. The mean decayed, missing and filled teeth number was 27. The average number of teeth with caries was 1.03 per person, the number of the teeth extracted was 6.9 per person and teeth with fillings 0.74 per person. The average number of teeth with root caries was 0.17. Approximately 9 teeth per person were in need of treatment. Filled teeth were found 25.9% of subjects and decayed teeth in 30.9%. The mean number of remaining sound teeth, decayed teeth and residual roots in the elderly decreased with increasing age. Complete periodontal treatment was required in 5.8% of the participants and no significant differences between genders in periodontal status could be noticed. Conclusion: The results of this study suggest poor dental health in this group of the institutionalised elderly and the necessity of improving and implementing some special features in the dental health services programs for the institutionalised elderly.     

Factors affecting the motivation for dental check‐ups and anxiety in the elderly in Tokyo

Objectives: The purpose of this study was to identify factors influencing the motivation for regular dental check‐ups and anxiety about future dental problems in the elderly. Background: Regular dental check‐ups are important to maintain oral health. Anxiety affects the quality of life of the elderly. However, few studies have investigated the factors influencing the motivation for regular dental check‐ups and anxiety in the elderly. Materials and methods: Among 452 elderly persons, 215 participants provided useful answers to our questionnaire. The questionnaire consisted of items concerning oral and living conditions of the subjects. Logistic regression analysis was conducted. Results: The mean age of the study sample was 75.7 ± 5.8 years. The percentage of edentulous subjects was 12.1%. The motivation for regular dental check‐ups was significantly positively correlated with the number of teeth present (p < 0.01), using inter‐dental brushes (p < 0.01), being on regular prescribed medication (p < 0.05), and having experience of providing oral care for the bedridden (p < 0.05). Anxiety about future oral problems was significantly associated with self‐rated health status (p < 0.01) and the presence of dentists who could be counted on to provide domiciliary visits (p < 0.05). Conclusion: The participants of this study had a high motivation for regular dental check‐ups, but were concerned about the future, particularly if they became bedridden.     

Recent novel approaches for population genomics data analysis

Next‐generation sequencing (NGS) technology is revolutionizing the fields of population genetics, molecular ecology and conservation biology. But it can be challenging for researchers to learn the new and rapidly evolving techniques required to use NGS data. A recent workshop entitled ‘Population Genomic Data Analysis’ was held to provide training in conceptual and practical aspects of data production and analysis for population genomics, with an emphasis on NGS data analysis. This workshop brought together 16 instructors who were experts in the field of population genomics and 31 student participants. Instructors provided helpful and often entertaining advice regarding how to choose and use a NGS method for a given research question, and regarding critical aspects of NGS data production and analysis such as library preparation, filtering to remove sequencing errors and outlier loci, and genotype calling. In addition, instructors provided general advice about how to approach population genomics data analysis and how to build a career in science. The overarching messages of the workshop were that NGS data analysis should be approached with a keen understanding of the theoretical models underlying the analyses, and with analyses tailored to each research question and project. When analysed carefully, NGS data provide extremely powerful tools for answering crucial questions in disciplines ranging from evolution and ecology to conservation and agriculture, including questions that could not be answered prior to the development of NGS technology.     

Patterns of dental caries and treatment experience in elderly Lithuanians

Objective: The aim of the study was to evaluate patterns of caries experience in a representative sample of Lithuanians, aged 65‐74. Methods: This cross‐sectional study included 301 participants (response rate 54%). Information was obtained from a clinical examination (caries experience, stimulated salivary flow rates and oral hygiene levels) and a questionnaire. The questionnaire comprised questions about oral, general, physical, mental and social health and about background, knowledge, attitudes and lifestyle. The study had a multidimensional approach to negative consequences of disease and positive aspects of health. For bivariate testing, t‐test, ANOVA and Spearman's correlation were used. Factor analysis was combined with linear multiple regression for a multivariate study of caries experience patterns. Results: Elderly Lithuanians were found to have lower levels of edentulousness (range 11‐15%) than elderly people in other European countries. The mean number of missing teeth was also lower than in any of the neighbouring countries. A comparison of dentate and edentulous groups did not show any major differences. Those who reported that they had general disease had higher levels of oral health maintenance. In dentate elderly, caries experience differed according to place of residence, fluoride content in the drinking water, socio‐economic status, gender, lifestyle, and many other factors. The multivariate approach explained 52%. 61% and 55% of the variation in the number of filled or sound teeth (FS‐T), delayed (DT) and missing teeth (MT) respectively. Conclusion: Levels of oral health maintenance and caries experience show substantial variation among elderly Lithuanians, according to many health‐related characteristics. These elderly people require appropriate oral care, just as much as people in other population sub‐groups.
