Self-reported oral hygiene habits among institutionalised elderly and their relationship to the condition of oral tissues in Taubaté, Brazil

Objectives: To record self‐reported hygiene habits, examine the oral conditions of a sample group of institutionalised elderly, and examine possible relationships between these habits and conditions. Design: Cross‐sectional. Setting: All the institutions for the elderly in Taubaté, Brazil. Subjects: The entire population of these institutionalised elderly people (n = 553). Intervention: The subjects were interviewed and underwent an oral examination. Main outcome measures: Oral hygiene habits, oral conditions and statistical relationships between habits and oral conditions were recorded. Results: The average age of the subjects who knew their age (n = 364) was 74.9 years (±12.9), and 64.7% of the sample group were females. Denture‐related stomatitis was found in 19.5%, impaired manual dexterity in 40%, dry mouth sensation in 36.3%, difficulty in performing oral hygiene in 20%, no oral hygiene‐related orientation in 54.1%, no periodic oral examinations in 59.5%, and no tongue cleaning in 68.3% was declared. Among dentate subjects, 73.3% had periodontal disease, 54.7% had caries, 26% reported no toothbrushing, and 7.3% reported flossing. Of the denture wearers, 7% did not brush their dentures. Denture‐related stomatitis showed a statistical relationship with impaired manual dexterity (p = 0.012) and an inverse statistical relationship with denture brushing frequency (p = 0.006). Periodontal disease showed an inverse relationship to flossing (p < 0.001) and tongue cleaning (p = 0.0026). Caries showed an inverse relationship with tooth‐brushing (p = 0.043), flossing (0.022), proper oral hygiene orientation (p = 0.041) and periodical check‐ups (p = 0.007). Conclusion: Oral hygiene practices in this sample group were found to be inadequate, and statistically significant relationships were verified between the lack of good oral hygiene practices and the deleterious oral conditions.     

Oral health in nursing home residents with different cognitive statuses

Objective: To compare oral health in nursing home (NH) residents with different cognitive statuses. Background: Oral health is a significant issue for NH residents because of its relationships to quality of life, systemic health and well‐being. It is known that oral health is poor in NH residents. However, how oral health differs in NH residents with different cognitive statuses remains unclear. Materials and methods: Nine hundred and two NH residents were retrospectively recruited from a community‐based geriatric dental clinic in Minnesota, USA. Comprehensive medical, dental, cognitive and functional assessments were completed for the participants. On the basis of medical history and cognitive status, participants were categorized into three groups: without cognitive impairment (non‐impaired group), with cognitive impairment but no dementia (impaired group) and with dementia (demented group). ANOVA, Chi‐square and Fisher’s exact tests were used to compare medical, dental and functional statuses between groups. Results: Oral hygiene was poor in NH residents. Forty per cent of participants in the impaired group were edentulous, significantly higher than the edentulism rate in the demented group (29%, p = 0.01). More than 60% of the participants lost 16 or more teeth prior to examination. Depending on their cognitive status, 82–92% of the participants arrived with one or more caries or retained root. Dentate participants in the impaired and demented groups averaged about six caries or retained roots, significantly more than 4.7 caries or retained roots in the non‐impaired group (p = 0.01). Conclusion: Oral health was poor but slightly different in NH residents with different cognitive and functional statuses.     

Are the barriers to good oral hygiene in nursing homes within the nurses or the patients?

doi: 10.1111/j.1741‐2358.2011.00554.x
Are the barriers to good oral hygiene in nursing homes within the nurses or the patients? Objective: To explore nursing home patients’ oral hygiene and their nurses’ assessments of barriers to improvement. Background: In nursing homes, nurses are responsible for patients’ oral hygiene. Materials and methods: This study assessed the oral hygiene of 358 patients in 11 Norwegian nursing homes. 494 nurses in the same nursing homes participated in a questionnaire study. Results: More than 40% of patients had unacceptable oral hygiene. ‘More than 10 teeth’ gave OR = 2, 1 (p = 0.013) and ‘resist being helped’ OR = 2.5 (p = 0.018) for unacceptable oral hygiene. Eighty percent of the nurses believed knowledge of oral health was important, and 9.1% often considered taking care of patients’ teeth unpleasant. Half of the nurses reported lack of time to give regular oral care, and 97% experienced resistant behaviour in patients. Resistant behaviour often left oral care undone. Twenty‐one percent of the nurses had considered making legal decisions about use of force or restraints to overcome resistance to teeth cleaning. Conclusion: Oral hygiene in the nursing homes needed to be improved. Resistant behaviour is a major barrier. To overcome this barrier nurses’ education, organisational strategies to provide more time for oral care, and coping with resistant behaviour in patients are important factors.     

Association between oral health, cognitive impairment and oral health-related quality of life

doi: 10.1111/j.1741‐2358.2011.00542.x
Association between oral health, cognitive impairment and oral health–related quality of life Objective: Investigating oral health–related quality of life’s (OH‐QoL) relationship with cognitive state. Background: Oral health affects OH‐QoL and is poor in institutionalised and cognitively impaired people. Material and Methods: This was a cross‐sectional study involving 215 institutionalised elderly (82.9 mean age), who were interviewed, examined and cognitively screened using the Pfeiffer test. Results: Mean GOHAI score was 53.1; only 43.7% of the participants reported having a good OH‐QoL. Needing help with dressing or washing (OR 2.14; p = 0.004), having one to nine teeth (OR 4.65; p ≥ 0.001), eight or less occluding pairs (OR 2.74; p = 0.002), one to three caries (OR 1.85; p = 0.005) and being cognitive impaired (OR 0.54; p = 0.034) were significantly associated with altered OH‐QoL in bi‐variate analysis. Being edentulous (OR 3.18; p = 0.0046), having 1–9 teeth (OR 2.62; p = 0.056) and presenting mild cognitive impairment (MCI) (OR 0.32; p = 0.016) appeared as predictive variables in logistic regression for having an altered OH‐QoL. Conclusions: Participants having MCI had significantly better GOHAI score than cognitively normal residents. Performing cognitive screening parallel to applying any OH‐QoL instrument would make the results more reliable and would benefit cognitively impaired people.     

Caries experience in existing and new nursing home residents in Adelaide,Australia

Objectives: The Adelaide Dental Study of Nursing Homes was instigated to provide comprehensive information concerning oral disease experience, incidence and increments in a random sample of those older South Australians residing in Adelaide nursing homes. Methods: This paper presents caries experience results for existing and new nursing home residents, and caries incidence and increments for existing residents, from dental inspections conducted at the baseline and one‐year data collections. Results: The residents in this study were very functionally dependent, medically compromised, cognitively impaired and behaviourally difficult older adults, the great majority of whom had moderate to severe cognitive impairment. Residents gave their carers many complex and challenging behavioural problems during oral hygiene care provision. Existing and new residents had similar dental history, oral hygiene, and socio‐detnographic characteristics, and similar cognitive, medical, functional, and nutritional status. Oral disease experience was high in both existing and new residents. There were no significant differences between existing and new residents for their dentate status, tooth status, coronal caries experience, or root caries experience, with the exceptions that new residents had significantly greater mean number of teeth, more filled coronal and root surfaces, and also new residents had significantly fewer decayed retained roots. Large numbers of tooth surfaces were covered in plaque and debris that negated more precise assessment of caries. The existing residents had caries increments on both coronal (2.5 surfaces) and root surfaces (1.0 surfaces) over the one‐year period. Coronal caries incidence was 64% and root caries incidence was 49% of existing residents. Conclusions: Oral disease experience was high in both existing and new residents. There were few significant differences between existing and new residents’ oral health status. New residents were being admitted to nursing homes with a compromised oral health status. Coronal and root caries increments and incidence were high for existing residents over the one‐year period.     

Edentulism and dental caries in Victorian nursing homes

doi: 10.1111/j.1741‐2358.2011.00510.x Edentulism and dental caries in Victorian nursing homes Objectives: The aim of this project was to investigate edentulism and dental caries in nursing home residents in Victoria, Australia. Background: The Australian population is ageing with a growing number of people living in nursing homes. These residents are at increased risk for dental caries, have more teeth present now than at any time in the past 50 years and often have difficulty maintaining adequate oral hygiene. Materials and methods: Clinical dental examinations were conducted at 31 nursing homes in Melbourne and regional Victoria between May 2005 and June 2006. A total of 510 residents were examined out of 1345 eligible participants. Socio‐demographic and medical history was collected via questionnaire. Results: Just over half of the residents were dentate (53.9%), and dentate residents had a mean of 14.4 teeth present and 2.66 untreated decayed teeth. Residents who required total assistance with oral hygiene had more decayed teeth and fewer filled teeth than residents who did not require assistance. Conclusions: Nursing home residents in Victoria are retaining an increasing number of natural teeth and have more tooth surfaces at risk for dental caries. Untreated dental caries was a significant problem for residents, particularly for those who are dependent on others for their daily oral hygiene care.     

Comparison between amine fluoride and chlorhexidine with institutionalized elders: a pilot study

doi: 10.1111/j.1741‐2358.2012.00650.x Comparison between amine fluoride and chlorhexidine with institutionalized elders: a pilot study Objective: Compare the efficacy of amine fluoride toothpaste and gel with chlorhexidine spray in an institutionalised population. Background: People who live in nursing homes have poorer oral hygiene because of their dependency for the basic activities of daily living as they rely on caregivers. Methods: Twenty‐six people over 65 years old who had at least four teeth and living in a nursing home. They were assigned to three groups: A: amine fluoride toothpaste and once a week amine fluoride gel (Elmex^®), B: 0.12% spray‐chlorhexidine once a day (Perio‐Aid^®) and C: brush teeth without toothpaste. The plaque and gingival index of Silness and Löe, General Oral Health Assessment Index, McLeran and Pfeiffer index were recorded, and the number of colonies of Streptoccocus mutans and Lactobacillus and the remineralisation of caries were evaluated using Diagnodent^®. Measurements were taken at the beginning of the study and after 6 months. Results: Twenty‐two people finished the study. No group showed a statistical difference in the plaque or gingival index, but there was a tendency to show improvement in the amine fluoride group. There was also no difference between the number of colonies of either S. mutans or lactobacillus. There was a significant difference between the plaque and gingival index and the cognitive status (p = 0.0054), along with their requirement for assistance to perform good oral hygiene (p = 0.0001). Both products remineralised the carious lesions in this period compared with the control group (p = 0.0151). Conclusion: The plaque and gingival indices did not improve during the study, but both products remineralised the previous caries lesions.     

Oral hygiene care status of elderly with dementia and in residential aged care facilities

doi: 10.1111/j.1741‐2358.2011.00472.x
Oral hygiene care status of elderly with dementia and in residential aged care facilities Objective: To explore the effectiveness of oral hygiene care on plaque and gingival status of residents with dementia. Background: Oral hygiene and oral hygiene care has been reported to be poor among the institutionalised elderly with dementia. The severity of oral diseases has been shown to increase with the severity of physical and cognitive impairment related with dementia. Little research has been carried out on plaque and gingival status of elderly with dementia and the impact of disability related with dementia on oral health in residential aged care facilities (RACF). Materials and methods: A cross‐sectional study of 205 elderly residing in RACF in Perth. Results: Forty‐one percent of the residents in RACF had dementia. Sixty percent of the residents with dementia and 75% of the residents with an Activities of Daily Living Oral Health score of D were assisted with oral care. Mean plaques scores and extent of gingival inflammation were higher for residents in the DD and D subgroups and resident with dementia. Residents assisted with brushing had higher mean plaque score and more moderate gingival inflammation. Conclusion: Oral hygiene care status in residents with dementia was poor despite the fact that oral care assistance was being provided.     

Oral health and treatment needs of the long-term hospitalised elderly

Objectives: To determine the oral health and treatment needs of the long‐term hospitalised elderly. Setting: The Laakso long‐term hospital, Helsinki, Finland. Design: A cross‐sectional study with clinical oral examinations. Subjects: All long‐term patients (n = 260) aged 60 and older. Main outcome measures: Edentulousness, presence and hygiene of dentures, mucosal findings, number of teeth, functioning teeth and tooth remnants, level of dental hygiene, and need for operative treatment. Results: Subjects’ mean age was 83.3 years (SD = 8.1); 42% were edentulous, 45% of women and 33% of men (p = 0.12). With no gender difference, 41% had removable dentures, but one in four were considered to be in need of repair or replacement. Denture hygiene was good in 19%, moderate in 44%, and poor in 37%, and for men worse than for women (p = 0.02). Stomatitis was found in 25%, and angular cheilitis in 28% of the denture wearers. The dentate subjects had on average 12.4 (SD = 8.6) teeth with a clear difference by age (p = 0.03), but no difference by gender. Dental hygiene was considered poor. Of the dentate subjects, 37% were in need of restorations, 51% of periodontal therapy and 42% of extractions. Conclusions: Oral cleanliness should be improved with regards to dentures and teeth. More attention should be focused on dental care of the long‐term hospitalised elderly.     

Oral hygiene and periodontal disease in Victorian nursing homes

doi: 10.1111/j.1741‐2358.2010.00448.x
Oral hygiene and periodontal disease in Victorian nursing homes Objective: To investigate oral hygiene and periodontal disease in residents of Victoria nursing homes. Background: The Australian population is ageing with a growing proportion of elderly Australians living in nursing homes. With declining edentulism rates, periodontal disease is becoming more prevalent in this population. Materials and methods: A total of 275 dentate residents from 31 Victorian nursing homes had a questionnaire and clinical examination using the Visual Plaque Index and a modified Community Periodontal Index. Results: Self‐reported oral hygiene habits of residents were poor, with less than one‐third of residents cleaning their teeth twice daily or more. Periodontal health was found to be extremely poor, and the prevalence of 4 mm+ periodontal pockets was 35.6%, with 10.2% having 6 mm+ pockets. Logistic regression found that age, gender, number of teeth present and oral hygiene were all strongly associated with the prevalence of 4 mm+ periodontal pockets. Conclusion: Poor oral hygiene and the presence of significant plaque and calculus were common findings in this study. Periodontal diseases are a significant problem for residents in nursing homes. Addressing this health issue will require improved training for carers and better access to appropriate dental services.     

Oral health of institutionalised elderly: a qualitative study of health caregivers’ perceptions in Brazil

doi: 10.1111/j.1741‐2358.2010.00366.x
Oral health of institutionalised elderly: a qualitative study of health caregivers’ perceptions in Brazil Objective: The aim of this study was to qualitatively explore caregivers’ perceptions of oral health care and factors influencing their work in a public long‐term care institution for the elderly in Goiania, Brazil. Method: Data were collected from a sample of 10 caregivers using personal in‐depth interviews and observation. Results: Caregivers were mainly nurses’ aides without training in oral health care. Oral health was associated with access to dental treatment, oral hygiene and use of dentures. Edentulousness, use of inappropriate dentures and appetite loss were perceived as negative images. Procedures used for oral hygiene were toothbrushing, mouth cleaning with a gauze and using a mouthwash. Conflicting priorities in routine care, lack of caregivers’ knowledge and the co‐operation of the elderly were the main obstacles to satisfactory oral care. Conclusion: Oral health care of the elderly was perceived as a burden by caregivers, and did not follow a standard protocol. Caregivers’ knowledge and perceptions reinforce the need for education and training in oral health issues.     

Oral health care in private and small long-term care facilities: a qualitative study

Objective: Elderly people who are institutionalised receive qualified care. Among the services supplied, oral health care has not always been a priority. The aim of this study was to identify the characteristics of oral health care provided to the elderly residents in long‐term care facilities (LTC) in Porto Alegre/RS city. Methods: Twelve private and small‐size LTCs (less than 20 residents) participated in this study. All supervisors and 36 carers were interviewed. The data obtained were organised according to the offer of oral health under the following categories: responsibility for oral care, oral care routines, difficulties carrying out oral care routines. Results: The procedures used most often in order of frequency were tooth brushing, prostheses cleaning, use of mouthwashes, soaking of prostheses and cleaning of the tongue. Among the difficulties mentioned were the high cost of dental assistance, the lack of co‐operation both by family members and by the elderly themselves, the oral and general health status of the elderly and the limited time available for carers to carry out the tasks. Oral care is conducted empirically, and the responsibility is left to the carers. Conclusions: Analysis of the statements given reveals that oral care does not follow any kind of protocol or standardisation. The persistence of this situation could lead to unsatisfactory oral health care in private and small LTC facilities.     

Predictors and correlates of edentulism in the healthy old people in Edinburgh (HOPE) study

Objectives: To determine the extent to which correlates of edentulism are explained by an association between tooth loss and cognitive ability. Methods: Participants in the Healthy Old People in Edinburgh (HOPE) study aged 70 or more at baseline were assessed and health, cognitive, socio‐economic and socio‐environmental data collected on four consecutive occasions. It was noted whether the participant had any retained teeth and if not, the age when the last tooth was lost. Prior determinants of edentulism were investigated with binary logistic regression models. At the 9‐year follow‐up, associations with edentulism were examined using general linear models with edentulism as an independent factor. Results: 201 participants were adequately tested, of whom 104 (51.7%) were edentulous. A logistic regression model that considered age, sex, education, social class, deprivation index of residence, objective distance from dentist, participant’s estimate of distance from dentist and NART‐estimated IQ (NARTIQ) found age (p = 0.032), occupational class (p = 0.019) and NARTIQ (p = 0.027) as significant predictors of edentulism. Cox’s proportional hazards modelling found only NARTIQ (p = 0.050) to be correlated. Being edentulous was associated with poorer respiratory function but not hand grip strength (p = 0.23). Edentulous participants had lower self esteem scores (p = 0.020) and poorer dietary assessment scores (p = 0.028). Being edentulous was also associated with significantly lower mean scores on all cognitive testing, although these associations became non‐significant after adjustment for NARTIQ and age. Conclusions: In healthy older people, edentulism is associated with relative impairment of cognitive ability, although this association is explained by the fact that lower original intelligence predisposes to edentulism and poorer performance on cognitive tests in old age. Once original intelligence is adjusted for, tooth loss is not related to cognitive ability. Tooth loss is, however, associated with poorer status across a wide range of health measures: physical health, nutrition, disability and self‐esteem. Establishing the degree to which these health outcomes are causally related to edentulism could usefully be factored into cost–benefit analyses of programmes designed to prevent tooth loss.     

Oral status in home-dwelling elderly dependent on moderate or substantial supportive care for daily living: prevalence of edentulous subjects, caries and periodontal disease

doi: 10.1111/j.1741‐2358.2011.00507.x Oral status in home‐dwelling elderly dependent on moderate or substantial supportive care for daily living: prevalence of edentulous subjects, caries and periodontal disease Objectives: The aim of this study was to compare the prevalence of edentulous subjects, caries and periodontal disease among the home‐dwelling elderly with moderate and substantial needs of support for daily living. Materials and method: A sample of 302 randomly selected elderly with moderate or substantial needs of supportive care were examined in Sweden. Several oral clinical variables were registered: number of teeth, dentures, caries, probing pocket depth, gingival bleeding and Eichner’s index. Results: Both in general and in oral health, the differences were small when comparing elderly with moderate and substantial care needs for daily living. Those with substantial needs had more caries lesions (p < 0.01) and more gingival bleeding (p < 0.05), while the number of teeth and prevalence of edentulous subjects did not differ in relation to the need of daily support. The elderly had, on average, 9.8–11.7 teeth, one‐third of whom had no natural teeth. According to Eichner’s index, half of the elderly in both groups had no opposing tooth contacts. Fifty‐five per cent used dentures. Conclusions: Elderly people with needs of supportive care have lost many teeth before they become dependent. Health promotion should be a priority in early ageing populations to prevent oral diseases and tooth loss.     

Factors associated with missing teeth in the Brazilian elderly institutionalised population

doi:10.1111/j.1741‐2358.2012.00655.x Factors associated with missing teeth in the Brazilian elderly institutionalised population Objective: Identify factors associated with missing teeth in the elderly institutionalised population in Brazil. Methodology: Cross‐sectional study of elderly institutionalised Brazilians with 1192 subjects. A questionnaire was applied as well as an epidemiological survey of oral health conditions in accordance with WHO. Factorial analysis was carried out with variables related to missing teeth, as well as the Fisher’s exact test, chi‐squared test and multiple logistic regression. Results: Mean age was 76.3 (±9.8), 53.5% (638) of subjects were women and 717 (60.2) were dependent. Mean of Decayed Missing and Filled Teeth Index (DMFT index) was 29.4 (±4.9). The subjects that did not use upper and lower dentures were 61.5% (732) and 79.2% (944), respectively. Median number of missing teeth per person was 27.88 (±6.8) with a mean of 4 (±6.6) teeth present and 2.4 (±4.5) caries‐free teeth. Factors associated with missing teeth following multivariate analysis were: age, sex, self‐assessment of oral health, access to health services, type of institution and area of the country. Conclusions: High level of tooth loss and low level of rehabilitation demonstrate precarious oral health. It is therefore necessary to improve institutional access mechanisms to public health facilities for the institutionalised elderly.     

Relative contribution of caries and periodontal disease in adult tooth loss among patients reporting to the Institute of Dental Sciences,Belgaum, India

Objectives: To examine the reasons for tooth loss in an adult population. Methods: Patients who reported to the department of prosthodontics in Institute of Dental Sciences, Belgaum, located in the north‐western part of the state of Karnataka, in the southern region of India over a period of 2 months, with at least one missing tooth (excluding third molars) constituted the sample size. There were a total of 365 patients (185 females and 180 males) within the age group of 16–84 years (mean age 51.06 ± 16.47 years) who fulfilled this criterion. Socio‐demographic profile was recorded along with a clinical examination for assessing the number and pattern of tooth loss. The reasons for tooth loss were recorded according to the history reported by the patient. Results: In the present study of 365 patients, 58.9% of the patients were completely edentulous, 41% were partially dentate, of which 20.8% had lost their teeth from caries, 11% from periodontal disease and 9.3% from a combination of reasons. More females had lost their teeth because of dental caries whereas more males had lost their teeth because of periodontal disease, this being statistically significant. (χ² = 16.53, p = 0.001). Highly significant results were obtained for age and reasons for tooth loss. (χ² = 150.39, p < 0.001). Irrespective of the socio‐economic status, dental caries was the most common cause for tooth loss in partially dentate patients though it was not statistically significant (χ² = 13.62, p = 0.325). Mandibular first molars were the teeth most frequently lost due to dental caries. The maxillary left central incisor was most frequently lost due to periodontal disease, followed by the maxillary right central incisor. Conclusions: Since both dental caries and periodontal disease contributed to tooth loss at different ages, risk indicators need to be identified.     

The clinical evaluation of the oral status in Alzheimer-type dementia patients

doi: 10.1111/j.1741‐2358.2010.00401.x
The clinical evaluation of the oral status in Alzheimer‐type dementia patients Background: To evaluate the oral health status in patients with Alzheimer dementia (AD), and the association of the disease severity with the oral findings. Methods: The study was conducted on the study group (31 AD patients) and the control group (47 healthy volunteers) from the Neurology Department of the Institute. Cognitive status was evaluated with the MMSE scoring system. Oral parameters, such as decaying, missing, filled teeth (DMFT) index and teeth present (PT) were evaluated in the patients. Oral hygiene status, denture status and mucosal lesions, including denture‐induced stomatitis were also investigated. Results: The study was conducted on the study group (31 AD patients) and the control group (47 healthy volunteers). Tooth brushing and denture cleaning were irregular in 22 of 31 (70%) patients with AD. The ratio of the subjects who forgot to remove their denture during the night was significantly higher in the study group than in the control group (p < 0.001). In this study, decreased cognitive functions in AD patients have been demonstrated to result in a deterioration of denture care and increased denture‐related mucosal lesions. Conclusions: These findings were considered due to decreased denture care including the non‐removal of the denture in the night in the patients with decreased cognitive functions.     

Oral hygiene of elderly people in long-term care institutions--a cross-sectional study

Objective: The aim of this cross‐sectional study was to assess the level of oral hygiene in elderly people living in long‐term care institutions and to investigate the relationship between institutional and individual characteristics, and the observed oral cleanliness. Materials and methods: Clinical outcome variables, denture plaque and dental plaque were gathered from 359 older people (14%) living in 19 nursing homes. Additional data were collected by a questionnaire filled out by all health care workers employed in the nursing homes. Results: Only 128 (36%) residents had teeth present in one or both dental arches. About half of the residents (47%) wore complete dentures. The mean dental plaque score was 2.17 (maximum possible score = 3) and the mean denture plaque score was 2.13 (maximum possible score = 4). Significantly more plaque was observed on the mucosal surface of the denture with a mean plaque score of 2.33 vs. 1.93 on the buccal surface (p < 0.001). In the multiple analyses only the degree of dependency on an individual level was found to be significantly correlated with the outcome dental plaque (odds ratio: 3.09) and only the management of the institution with denture plaque (odds ratio: 0.43). Conclusion: Oral hygiene was poor, both for dentures and remaining teeth in residents in long‐term care institutions and only the degree of dependency of the residents and the management of the institutions was associated with the presence of dental plaque and denture plaque respectively.     

Tooth loss and associated factors in long-term institutionalised elderly patients

Objective: To compare partial and total tooth loss in dependent institutionalised elderly patients and identify any associated factors. Background: A poor oral health status, together with a reduction of autonomy can seriously affect the general health and increase the risk of death in elderly people. Those with total tooth loss and in need of assistance are the most at risk. Materials and methods: In 2004, a cross‐sectional study of 321 elderly patients was conducted in long‐term hospital services provided in Montpellier, France. Socio‐demographic, behavioural, medical and oral health information was recorded for each patient. Multivariate logistic regression models were performed to test the relationship between those covariates and partial or total tooth loss. Pearson chi‐squared tests were used for bivariate analyses. Results: The proportion of edentulousness was 26.9%; among these12.6% had no dentures. The factors significantly associated with edentulism were: an age ‘older than 87 years’ [odds ratio (OR) = 9.4], the presence of a nephropathy (OR = 6.8), and inadequate oral hygiene (OR = 0.1). The factors most significantly associated with partial tooth loss (at least 21 missing teeth) were ‘cancerous disease’ (OR = 9.9), the presence of a nephropathy (OR = 5.6) and the presence of a neurological disease (OR = 4.1). The factors significantly related to dentate status (20 or more natural teeth retained) were ‘hypertension treatment’ (OR = 2.4), and ‘cortisone treatment’ (OR = 0.2). Conclusion: General health problems as well as a poor oral condition were significant risk indicators for tooth loss among the long‐term institutionalised elderly. This suggests that the number of remaining teeth has a strong effect on oral health‐related quality of life.
