The antecedents of oral care in nursing facilities - a qualitative interview study among supervisor nurses.

OBJECTIVES: This qualitative study describes the views of supervisor nurses related to antecedents of oral care in Finnish nursing facilities. METHODS: In the six largest cities in Finland, 19 supervisor nurses were interviewed and asked five semi-structured questions related to the antecedents of oral care in the units. The interviews were analyzed using inductive content analysis. RESULTS: Qualitative content analysis revealed five main categories: awareness of nurses (3 categories, 9 subcategories), attitude and motivation (3 categories, 10 subcategories), supporting quality of life and health (4 categories, 11 subcategories), the meaning of oral health in the unit (3 categories, 10 subcategories), and the role of the supervisor nurse in oral health care (4 categories, 14 subcategories). The awareness of nurses regarding oral health was in most cases good. Nurses' attitudes towards oral health and their motivation to oral care vary but were mostly good. Nurses were aware that oral care enhances the quality of life. The role of the supervisor nurse in organizing oral care was crucial. CONCLUSIONS: The performed analysis identified five main categories to describe antecedents for oral care in Finnish nursing facilities. The categories that needed to be improved were knowledge and attitude, and motivation related to oral care.

Implementation of oral hygiene practices in nursing homes - a qualitative approach among supervisor nurses.

OBJECTIVES: This study describes daily oral health care in private enhanced service housing units and nursing homes in Finland using a qualitative method. METHODS: Nineteen supervisor nurses were interviewed in the six largest cities in Finland. The interviews consisted of semi-structured questions. The interviews were then transcribed and analyzed using inductive content analysis. RESULTS: The qualitative content analysis revealed five main categories: diet, education in the oral health of older people, oral care equipment and taking care of them, caring for the mouths of residents, and professional oral health care. The results revealed that sugary snacks were given daily in the units and there was a need for oral health care education. The dental equipment of residents was taken care of well and the oral health of the residents was taken care of moderately well. Furthermore, there was a need for co-operation between dental professionals and only half of the residents had an individual oral care plan. CONCLUSIONS: It can be concluded that based on this qualitative study, the implementation of daily oral health care in most nursing homes and enhanced housing units seems to be at a sufficient level and more oral health-related practical and theoretical education is needed.

High anticholinergic burden and hyposalivation and xerostomia in the elderly.

OBJECTIVE: The aim was to study the association between high anticholinergic burden and hyposalivation and xerostomia among older people. BACKGROUND: Anticholinergic drugs have been shown to cause xerostomia and hyposalivation. Yet there are few studies on the association between anticholinergic burden and hyposalivation and xerostomia in the elderly. MATERIAL AND METHODS: The study population consisted of community-dwelling older people (n = 321, mean age 81.6 years) from the Oral health GeMS study. Participants provided salivary samples and xerostomia was determined with a questionnaire. The baseline data were collected by interviews, oral clinical examinations and from patient records. Each participant's anticholinergic burden was determined by eight anticholinergic scales. Poisson regression models with robust error variance were used to estimate relative risks (RR) with a 95% confidence interval (CI). RESULTS: RRs of high anticholinergic burden in anticholinergic scales for xerostomia (multiple symptoms) ranged from 1.02 to 1.68; for low unstimulated salivary flow (≤0.1 mL/min) from 1.47 to 1.67; and for low stimulated salivary flow (≤0.7 mL/min) from 0.99 to 2.07. A high anticholinergic burden according to seven out of eight scales was associated (p < .05) with hyposalivation or xerostomia. CONCLUSIONS: A high anticholinergic burden was associated more strongly with hyposalivation (both unstimulated and stimulated) than with xerostomia.

Association between bleeding periodontal pockets and eczemas: Results of the Northern Finland Birth Cohort 1966.

AIM: To investigate whether the periodontal condition as measured by bleeding periodontal pockets is associated with atopic dermatitis, seborrheic dermatitis, and eczema nummulare. MATERIALS AND METHODS: The study population (n = 1871) was obtained from the 46-year follow-up study of the Northern Finland Birth Cohort 1966 study (NFBC1966). The periodontal condition was measured by the number of sites with bleeding periodontal pockets that were ≥4 mm deep. The whole skin of the participants was clinically examined, and diagnoses of skin diseases were made according to the International Classification of Diseases. Prevalence rate ratios (PRR) and 95% confidence intervals (95% CIs) were estimated using Poisson regression models with robust error variance. RESULTS: In this cohort, comprising 46-year-old participants of NFBC1966, the presence of 1-3 and ≥4 bleeding-deepened periodontal pockets (≥4 mm deep) were associated with seborrheic dermatitis (PRR 1.9, 95% CI: 1.3-2.8 and PRR 2.2, 95% CI: 1.4-3.3, respectively) and with eczema nummulare (PRR 1.7, 95% CI: 0.9-3.1 and PRR 1.7, 95% CI: 0.9-3.3, respectively). For non-smokers, the corresponding estimates were 1.7 for seborrheic dermatitis (95% CI: 1.1-2.6) and 1.8 (95% CI: 1.1-3.1) and 1.4 for eczema nummulare (95% CI: 0.7-2.9) and 1.2 (95% CI: 0.5-2.9), respectively. No association was found between bleeding-deepened periodontal pockets and atopic dermatitis. Further adjustments for C-reactive protein, diabetes, and inflammatory diseases did not essentially change the risk estimates among either the total population or the non-smokers. CONCLUSION: Bleeding periodontal pockets appeared to be associated with the presence of seborrheic dermatitis and eczema nummulare.

Implementation of oral hygiene practices in nursing homes - the view of supervisor nurses.

OBJECTIVES: The aim of our study was to analyse the implementation of oral health-related practices in private enhanced service housing units and nursing homes in Finland reported by supervisor nurses. METHODS: We sent an anonymous, voluntary Webropol-questionnaire to the supervisor nurses of private enhanced service housing units and nursing homes (N = 245). The questionnaire included items about the implementation of oral healthcare-related practices in the care units and items based on the Nursing Dental Coping Beliefs index (DCBS index). Five dimensions of the implementation of oral healthcare-related practices, Oral hygiene practices and Favourable diet for oral health, Oral hygiene equipment, Professional dental services, and Knowledge and opinions were used as outcomes. The factors in the nursing DCBS index and background variables were used as explanatory variables. RESULTS: Our main results showed that in care units, Oral hygiene practices, Favourable diet for oral health, Oral hygiene equipment, and Professional dental services were partly implemented. Furthermore, according to Knowledge and opinions supervisor nurses had challenges in oral health-related knowledge and difficulties in managing oral care. In the DCBS index, better self-efficacy in "Managing bleeding gums" was associated with better implementation of oral health practices. Furthermore, supervisor nurses' better own oral health habits were associated with better implementation of oral health-related practices. CONCLUSIONS: It can be concluded that based on the responses of the supervisor nurses, oral health-related practices were partly implemented in private enhanced service housing units and nursing homes in Finland.

Developing an Instrument to Measure Self-Efficacy, Challenges and Knowledge in Oral Care among Geriatric Home Care Nurses-A Pilot Study.

The role of geriatric nurses is essential in preventing oral health problems of older people with impaired daily functioning. Nurses have reported low self-efficacy with regard to oral health care practices and wish to receive more information on the topic. The main aim of this pilot study was to develop an instrument to measure the self-efficacy beliefs, challenges and knowledge of geriatric home care nurses with regard to the oral health care of older. A questionnaire was developed to evaluate geriatric home care nurses' self-efficacy beliefs, challenges and knowledge regarding the oral health care of the older people. In this case, 18 nurses participated in a one-day intervention and filled in the questionnaire before and after the intervention. The comments and questions of the nurses were analysed utilising the principles of inductive content analysis. Cronbach's alpha for the scales varied between 0.69-0.79. The interactive intervention improved both nurses' self-efficacy beliefs and oral health-related knowledge, and most of the challenges faced by nurses in older people's oral health care were diminished. Financial resources and older people's self-determination were the most common limitations to oral care. In this pilot study, we developed an instrument to measure geriatric home care nurses' self-efficacy beliefs, challenges and knowledge regarding older people's oral health care. In the future, this instrument can be validated with a larger study population.

Anticholinergic burden, oral hygiene practices, and oral hygiene status-cross-sectional findings from the Northern Finland Birth Cohort 1966.

OBJECTIVES: To study the association between anticholinergic burden and oral hygiene practices and oral hygiene status among 46-year-old people. MATERIALS AND METHODS: The study included 1945 participants from the Northern Finland Birth Cohort 1966 (NFBC1966), who had a complete dental status. The participants underwent clinical medical and dental examinations, and their medication data were gathered by combining self-reported drug use with information from the National Prescription Register. Anticholinergic burden was measured using nine previously published anticholinergic scales. Oral hygiene practices were assessed with toothbrushing frequency and oral hygiene status with the presence of visible dental plaque. Poisson regression with robust variance estimation and negative binomial regression models were used to estimate relative risks (RR). RESULTS: Thirty percent of the participants reported brushing their teeth twice a day and about 25% of their teeth had dental plaque on them. Fifteen percent of the participants used at least one anticholinergic drug or had an anticholinergic burden according to the nine anticholinergic scales. After adjustments for confounding factors, the RRs of anticholinergic burden varied between 0.95 and 1.11 for toothbrushing frequency. Anticholinergic burden (according to Anticholinergic Activity Scale, Anticholinergic Cognitive Burden, Chew's scale) was associated statistically significantly with the number of teeth with dental plaque. For the three scales, RRs varied from 1.24 to 1.50. CONCLUSIONS: Anticholinergic burden associated with poor oral hygiene. CLINICAL RELEVANCE: The findings stress the importance of providing oral hygiene instructions and prophylactic measures to patients taking anticholinergic drugs.

Physical ability and comorbidity and oral health among home-dwelling older people in the Finnish population.

AIM: To examine how physical ability and comorbidity associate with oral health. METHODS AND RESULTS: The study population comprised 161 individuals belonging to the Oral Health GeMS study. Outcome variables were the number of teeth with dental caries and deepened periodontal pockets and self-perceived oral health (pain/discomfort in mouth). Physical ability was determined by measuring limitations in daily activities (activities of daily living [ADL] and instrumental activities of daily life [IADL]) and the number of comorbidities with Functional Comorbidity Index (FCI). Poisson's multivariate regression model was used to estimate prevalence rate ratio (PRR) and their 95% confidence intervals (CI). The physical ability or number of comorbidities did not associate consistently with oral diseases, but ADL, IADL and FCI associated all with self-perceived oral discomfort (PRR: 1.74, CI: 1.01-3.03; PRR: 1.20, CI: 1.06-1.35; PRR: 1.20, CI: 1.05-1.36, respectively). Furthermore, IADL associated also with poor self-perceived oral health (PRR: 1.27, CI: 1.03-1.57). CONCLUSION: Older people with impaired physical ability and comorbidities are more likely to have oral discomfort and have poorer self-perceived oral health.

Oral diseases and inflammatory burden and Alzheimer's disease among subjects aged 75 years or older.

AIM: To study whether dental caries, periodontal disease, and stomatitis, and the related inflammatory burden associate with diagnosed Alzheimer's disease (AD) and dementia among older people. METHODS: The study population included 170 individuals aged ≥75 years. The primary outcome was diagnosed AD and the secondary outcome was any types of diagnosed dementia. Information about participants' oral diseases and the related inflammatory burden was based on the clinical oral examination. Relative risks (RRs) and confidence intervals (CIs) were estimated using regression models. RESULTS: Dental caries, the presence of ≥3 carious teeth (RR: 3.47, 95% CI: 1.09-11.1) and the number of carious teeth (RR: 1.24, CI: 1.11-1.39), and inflammatory burden (RR: 1.44, CI: 1.04-2.01) were associated with a higher likelihood of having AD. Also, periodontal disease and stomatitis were associated, although nonstatistically, with AD and dementia. The risk estimates for any type of dementia were in most cases lower than for AD. CONCLUSION: Oral diseases and the related inflammatory burden were in most cases associated more strongly with diagnosed AD than dementia in general. Of the oral diseases studied, the strongest association was between dental caries and AD.

Perceptions of older people's oral health care among nurses working in geriatric home care.

OBJECTIVES: This study investigates nurses' self-reported experiences and perceptions of older people's oral health care using a qualitative method. METHODS: We interviewed 10 nurses working in geriatric home care who regularly visit and take care of older people in their homes. The interviews consisted of semi-structured questions. The interviews were then transcribed and analysed. RESULTS: All nurses were aware of the connection between oral health and general health, but more detailed knowledge about oral health was lacking and confidence in oral health care practices was limited. Many of the interviewees noted the cleaning of removable dentures and problems related to them, but did not mention anything about periodontal diseases. Oral health education among the nurses was rare. The nurses reported lack of time to take care of their clients' oral health. As possible development steps, the interviewees suggested that including oral health care in the daily treatment plan would improve oral health care practices. CONCLUSIONS: The nurses' lack of knowledge about oral health care and uncertainty in oral health practices among older people are major problems in daily geriatric home care. Oral health education and confidence in oral health practices should be improved in both basic and on-the-job education.

Anticholinergic burden and dry mouth among Finnish, community-dwelling older adults.

OBJECTIVE: The aim was to study whether the anticholinergic burden of drugs is related to xerostomia and salivary secretion among community-dwelling elderly people. BACKGROUND: Anticholinergic drugs have been shown to be a risk factor for dry mouth, but little is known about the effects of cumulative exposure to anticholinergic drugs measured by anticholinergic burden on salivary secretion or xerostomia. METHODS: The study population consisted of 152 community-dwelling, dentate, non-smoking, older people from the Oral Health GeMS study. The data were collected by interviews and clinical examinations. Anticholinergic burden was determined using the Anticholinergic Drug Scale (ADS). A Poisson regression model with robust error variance was used to estimate relative risks (RR) with 95% confidence intervals (CI 95%). RESULTS: Participants with a high-anticholinergic burden (ADS ≥ 3) were more likely to have xerostomia (RR: 3.17; CI: 1.44-6.96), low-unstimulated salivary flow (<0.1 mL/min; RR: 2.31, CI: 1.22-4.43) and low-stimulated salivary flow (<1.0 mL/min; RR: 1.50, CI: 0.80-2.81) compared to reference group (ADS 0). In participants with a moderate anticholinergic burden (ADS 1-2), all the risk estimates for xerostomia, unstimulated and stimulated salivary secretion varied between 0.55 and 3.13. Additional adjustment for the total number of drugs, antihypertensives and sedative load caused only slight attenuation of the risk estimates. CONCLUSION: A high-anticholinergic burden was associated with low-unstimulated salivary secretion and xerostomia.

Waist circumference and waist-to-height ratio are associated with periodontal pocketing-results of the Health 2000 Survey.

BACKGROUND: Body mass index (BMI) has been found to associate with different parameters of chronic periodontal disease in previous studies. It is reasonable to expect that central adiposity measures, such as waist circumference and waist-to-height ratio, which indirectly takes into account visceral fat, are more accurate measures of obesity-related oral health risks than BMI. The aim of this study was to examine whether central obesity is associated with periodontal pocketing, an indication of infectious chronic periodontal disease. METHODS: The study was based on a subpopulation from the national Health 2000 Survey in Finland. It included dentate, non-diabetic, never-smoking subjects aged 30-49 (n = 1287). The outcome variable was the number of teeth with deepened periodontal pockets (4 mm or more) and the number of teeth with deep periodontal pockets (6 mm or more). Central obesity was measured by means of waist circumference (WC) and waist-to-height ratio (WHtR). Poisson regression models were used to estimate prevalence rate ratios (PRR) and their 95% confidence intervals. RESULTS: Our main finding was that both WC and WHtR were associated with the number of teeth with deeper (4 mm or more) periodontal pockets; the PRR for the fifth quintile in WC was 1.5, CI: 1.2-1.9 and in WHtR 1.4, CI: 1.1-1.7, when compared to the lowest quintile. Corresponding figures for deep (6 mm or more) periodontal pockets were 2.3, CI: 0.9-6.1 for WC and 1.9, CI: 0.8-4.4 for WHtR. There were no essential differences in the strengths of the associations between WC and WHtR and the number of teeth with deepened periodontal pockets. CONCLUSION: Both central adipose measures-WC and WHtR-seem to be associated with periodontal pocketing in non-diabetic, never-smoking subjects aged 30-49 years old.

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.

Sedative load and salivary secretion and xerostomia in community-dwelling older people.

OBJECTIVE: The aim was to investigate how sedative load and the total number of drugs used are related to hyposalivation and xerostomia among 75-year-old or older dentate, non-smoking, community-dwelling people. MATERIALS AND METHODS: The study population consisted of 152 older people from the Oral Health GeMS study. The data were collected by interviews and clinical examinations during 2004-2005. Sedative load, which measures the cumulative effect of taking multiple drugs with sedative properties, was calculated using the Sedative Load Model. RESULTS: The results showed that participants with a sedative load of either 1-2 or ≥3 had an increased likelihood of having low stimulated salivary flow (<0.7 ml/min; OR: 2.4; CI: 0.6-8.6 and OR: 11; CI: 2.2-59; respectively) and low unstimulated salivary flow (<0.1 ml/min; OR: 2.7, CI: 1.0-7.4 and OR: 4.5, CI: 1.0-20, respectively) compared with participants without a sedative load. Participants with a sedative load ≥3 had an increased likelihood of having xerostomia (OR: 2.5, CI: 0.5-12) compared with participants without a sedative load. The results showed that the association between the total number of drugs and hyposalivation was weaker than the association between sedative load and hyposalivation. CONCLUSION: Sedative load is strongly related to hyposalivation and to a lesser extent with xerostomia. The adverse effects of drugs on saliva secretion are specifically related to drugs with sedative properties.

Oral health intervention among community-dwelling older people: a randomised 2-year intervention study.

OBJECTIVE: The aim of this study was to investigate the effects of a 2-year oral-health-promoting intervention on oral health behaviour and oral health among people aged 75 years or older. MATERIALS AND METHODS: In a 2-year randomised intervention study, 279 community-dwelling older people completed the study: 145 persons in an intervention group and 134 in a control group. Interviews and clinical oral examinations were performed at the beginning of the study and at a 2-year follow-up. Changes in oral health behaviour and oral health were used as outcomes. INTERVENTION: Oral health intervention included individually tailored instructions for oral and/or denture hygiene, relief of dry mouth symptoms, decrease of sugar-use frequency, use of fluoride, xylitol or antimicrobial products, and professional tooth cleaning. RESULTS: More participants in both the intervention and control groups had better dental and denture hygiene and were free of oral diseases or symptoms at the 2-year follow-up than at the baseline. The differences in changes in outcomes between the intervention and control groups were not statistically significant. CONCLUSION: The results of this study showed that oral health of community-dwelling older people could be improved. Oral health improved in both groups, more among the participants in the intervention group compared with control group, but the effect attributed to oral-health-promoting intervention remained small.

Characteristics and medical-care-seeking of head and neck cancer patients: a population-based cross-sectional survey.

OBJECTIVES: Well-known risk factors, such as smoking and alcohol consumption, easily denounce head and neck cancer patients as smokers, alcohol abusers, and persons who are socially excluded and have low socioeconomic status. To diagnose these patients as early as possible, we should not have a prejudiced assumption of their characteristics. MATERIALS AND METHODS: We collected detailed data on patient characteristics and health behavior and explored whether these traits had any effect on seeking medical advice in a population-based cross-sectional study involving 85 patients with head and neck cancer diagnosed between January 2003 and December 2007, residing in two health care districts (population 1,600,000) in Finland. The data were gathered from patient charts and questionnaires. The questionnaire data were compared with the general population in Finland. RESULTS: We found these patients to be ordinary elderly people whose demographic and social features resembled those of the general population. They smoked more often, but otherwise had a rather healthy lifestyle. Only half were aware that smoking and alcohol consumption were risk factors of head and neck cancer. In a multivariate analysis, fear of physicians (adjusted odds ratio 11.0; 95% confidence interval 1.2-103), medical-care-seeking for symptoms other than pain (18.5; 2.2-156), and not suspecting cancer (11.2; 1.7-75.1) were independent risk factors for delayed consultation (combined appraisal and help-seeking interval over 3 months). CONCLUSION: Head and neck cancer patients deviated from the same-aged general population only in excessive smoking. Fear of doctors, having no pain, and no suspicion of cancer resulted in delayed medical-care-seeking.

Determinants for preventive oral health care need among community-dwelling older people: a population-based study.

The aim was to study the determinants of preventive oral health care need among community-dwelling old people. The study population consisted of 165 participants, a subpopulation in the Geriatric Multidisciplinary Strategy for Good Care of Elderly People (GeMS) study. Fifty-five percent of the edentate participants with full dentures and 82% of the dentate had a need for preventive oral health care. In the total study population, the need for preventive care was associated with co-morbidity (measured by means of the Modified Functional Co-morbidity Index) odds ratios (OR) 1.2 (confidence intervals [CI] 1.0-1.5), being pre-frail or frail, OR 2.5 (CI 1.2-5.1), presence of natural teeth, OR 4.8 (CI 2.2-10.4), and among dentate participants, the use of a removable partial denture, OR 12.8 (CI 1.4-114.4). Primary care clinicians should be aware of the high need for preventive care and the importance of nonoral conditions as determinants of preventive oral health care need.

Salivary flow rate and risk of malnutrition - a study among dentate, community-dwelling older people.

OBJECTIVE: To analyse the relation between unstimulated and stimulated salivary secretion and the risk of malnutrition among home-dwelling elderly people. BACKGROUND: Saliva has an important role in eating. Despite this, there are only a few studies on the role of salivary secretion in the development of malnutrition among elderly people. MATERIALS AND METHODS: The study population consisted of 157 subjects aged 75 or older. This was a part of GeMS study carried out in Kuopio, in eastern Finland. The data used in this study were collected by means of interviews and geriatric and oral clinical examinations. The risk of malnutrition was measured using the Mini Nutritional Assessment Short-Form. Logistic regression models were used to estimate odds ratios (OR) and their 95% Confidence Intervals (CI). RESULTS: Subjects with a low unstimulated salivary flow rate (<0.1 ml/min) or stimulated salivary flow rate (<1.0 ml/min) had no statistically significant increase in risk of malnutrition, OR: 1.3, CI: 0.5-3.9, OR: 1.5, CI: 0.5-4.2, respectively, when compared with those with a normal unstimulated and stimulated salivary flow rate. CONCLUSION: Our results do not support the concept that low salivary secretion is an important risk factor for malnutrition among community-dwelling elders.

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

OBJECTIVE: To study the associations of instrumental activities of daily living (IADL) and the handgrip strength with oral self-care among dentate home-dwelling elderly people in Finland. MATERIALS AND METHODS: The study analysed data for 168 dentate participants (mean age 80.6 years) in the population-based Geriatric Multidisciplinary Strategy for Good Care of the Elderly (GeMS) study. Each participant received a clinical oral examination and structured interview in 2004-2005. Functional status was assessed using the IADL scale and handgrip strength was measured using handheld dynamometry. RESULTS: Study participants with high IADL (scores 7-8) had odds ratios (ORs) for brushing their teeth at least twice a day of 2.7 [95% confidence intervals (CI) 1.1-6.8], for using toothpaste at least twice a day of 2.0 (CI 0.8-5.2) and for having good oral hygiene of 2.8 (CI 1.0-8.3) when compared with participants with low IADL (scores ≤6). Participants in the upper tertiles of the handgrip strength had ORs for brushing the teeth at least twice a day of 0.9 (CI 0.4-1.9), for using the toothpaste at least twice a day of 0.9 (CI 0.4-1.8) and for good oral hygiene of 1.1 (CI 0.5-2.4) in comparison with the study subjects in the lowest tertile of handgrip strength. CONCLUSION: The results of this study suggest that the functional status, measured by means of the IADL scale, but not handgrip strength, is an important determinant of oral self-care among the home-dwelling elderly.

Dementia and oral health among subjects aged 75 years or older.

OBJECTIVE: To study the association between diagnosed dementia and oral health, focusing on the type of dementia, among an elderly population aged 75 years or older. BACKGROUND: Elderly people with dementia are at risk from oral diseases, but to date, only a few studies have analysed the association between type of dementia and oral health, and their results are inconclusive. MATERIALS AND METHODS: This cross-sectional study is based on the Geriatric multi-disciplinary strategy (Gems) study that included 76 demented and 278 non-demented subjects. The data were collected by means of an interview and an oral clinical examination. The type of dementia was diagnosed according to DSM-IV criteria. Poisson's and logistic regression models were used to determine relative risks (RR), odds ratios (OR) and 95% confidence limits (CI). RESULTS: Our results showed that patients with Alzheimer's disease and those with other types of dementia had an increased likelihood of having carious teeth, teeth with deep periodontal pockets, and poor oral and denture hygiene, compared with non-demented persons. The results showed that the type of dementia does not seem to be an essential determinant of oral health. CONCLUSIONS: Among the elderly aged 75 years or older, patients with Alzheimer's disease or other types of dementia are at increased risk of poor oral health and poor oral hygiene.
