Exploring the quality of life after denture‐wearing within elders in Kaohsiung Objective: The objective of the research is to investigate whether the elderly people’s quality of life get improved after denture wearing. Material and methods: About 1600 elderly persons, over 65 years old, were sampled as the research target. The overall response rate was 71.62%. The tool of research is a structural questionnaire Oral Health Impact Profile (OHIP) that was used to measure the oral health–related quality of life. Individual’s satisfaction of denture wearing divides into three groups: edentulous individuals who are satisfied with denture wearing, edentulous individuals who are not satisfied with denture wearing and dentulous individuals. Results: The result shows the eight variables, which are oral health condition, frequency of snacks‐eating, age, frequency in participation in social activities, instrumental activities of daily living (IADL), vision, satisfaction with life and physical functions, have significant influence on total OHIP score. Conclusions: Although being edentulous, if the elderly are satisfied with their denture, the quality of life can be maintained and not affected by oral health problems. It is suggested that the further researches can include more relevant factors when in a discussion on the oral health–related quality of life, especially, the subjective perception of individual’s feeling.     

Success of dental implants in elderly people--a literature review

Implant-supported dentures seem particularly appropriate for the predicament of being elderly and becoming edentulous. The aim of this article was to review the literature on success of dental implants in elderly people. The results of two studies suggested that the treatment with implants can be considered safe and predictable for older as well as for younger patients. Three studies found no increased implant failure-rate in patients with a compromised medical status. Four studies revealed high success-rates of dental implants among groups of elderly people. Within the limitations of this review of the literature it can be concluded that old age does not seem to represent a factor of major prognostic significance in treatment with dental implants.     

The influence of age and denture wear on the size of edentulous structures

Objectives : This study was designed to evaluate the influence of age and denture use on the size of arches and residual ridges in edentulous patients. Design : At two nursing homes, maxillary and mandibular stone casts of 302 fully edentulous patients were utilized to measure the size of the arches and residual ridges, according to age and use of complete dentures. Age cohorts were divided into three groups; 60–69, 70–79, and 80–89 years old. Two hundred and forty‐nine denture wearers used complete dentures for at least 2 years before examinations. Fifty‐three non‐denture users had never worn removable prostheses. Chi‐square analysis (p<0.05) was used to establish the possible relations between the linear values and the size indexes of the ridges and arches and the two examined parameters: age and denture wear. Results : Young old patients possessed edentulous structures that were not significantly larger than elderly old patients in both the maxilla and the mandible. Non‐denture users had significantly bigger arches and ridges in both edentulous jaws than denture users. Conclusions : Young old, non‐denture users tended to have bigger residual edentulous tissues compared to elderly old patients who used complete dentures.     

Care Needs of the Elderly Treated at a Dental School1

Increased longevity and recently intensified emphasis on gerodontology mandate that dental students'exposure to clinical care of the elderly be enhanced. The extent to which individual students can be exposed to geriatric dental care depends on the availability of elderly patients to dental school clinics and the treatment needs of these patients. The purposes of this study were (1) to determine the dental treatment needs of geriatric patients who seek care at a dental school, and (2) to ascertain if differences exist between the needs of older versus relatively young geriatric patients. Data collected on 128 elderly patients during a three month period indicate that 57% of the aged were either edentulous at examination or treatment planned to become edentulous and receive two full dentures. The remaining 43% were treatment planned to remain dentulous and receive therapies other than full upper and lower dentures. More older geriatric patients required full dentures than their younger cohorts. More young elderly required prophylaxes, scalings, root planing therapy, dental restorations, and partial dentures. Additional to their denture requirements, aged patients appear to have sufficient non-prosthetic needs to allow for meaningful gerodontic experience by students.     

Linear vertical jaw resorption potential in elderly complete denture wearers: a five-year follow-up study

Human bones decrease in quality and increase in porosity beginning at about the third decade of life. The aim of this study was to establish an equation to predict the maxillary and mandibular linear vertical resorption potential for elderly edentulous patients on the basis of the analysis of the cervical vertebrae in a single cephalometric radiograph. The morphology of the bodies of the third and fourth cervical vertebrae and measurements of linear vertical resorption in the frontal region of the jaws were analyzed in two consecutive cephalometric observations of 26 elderly edentulous patients over the five-year period of wearing complete dentures. An equation was determined to obtain maxillary and mandibular linear vertical resorption on the basis of measurements in the third and fourth cervical vertebral bodies and the average errors between the predicted and the actual values were 0.14 mm. The cervical vertebrae exhibited significant decrease in the height and width, and residual alveolar ridges exhibited significant decrease in the height over the 5-year period of wearing dentures (p < 0.01). These results suggest that using cervical vertebral measurements might allow predicting the maxillary and mandibular resorption for edentulous elderly patients wearing complete dentures.     

A Review of Regional Studies on the Dental Health of Older Canadians1

The last national survey of dental health in Canada was conducted in 1970–72 as part of the Nutrition Canada study. In that survey, 52% of Canadians over 60 were found to be edentulous. In 1980, epidemiologists in Quebec conducted the only provincewide, population-based survey of seniors and found 72% were edentulous. In Ontario, published local or regional surveys and province-wide interview data, obtained over the past 20 years, show that between 81% and 51% of those over 65 years of age were edentulous with the lower rates found in the more independently living, younger elderly, and in the more recent studies. Further, between 18% and 42.5% of those over 65 had visited a dentist in the previous year with higher rates among dentate and independently living elderly. Dental treatment needs were higher among the dentale and the institutionalized. These data are contrasted with recent findings from a population-based study in East York, Ontario, and local data from British Columbia, Manitoba, and Prince Edward Island. The regional differences in health and the trends to increased life span, less edentulism and increased rates of visiting present challenges to Canadian policy makers and dental practitioners.     

Age-related satisfaction with complete dentures,desire for improvement and attitudes to implant treatment

In the edentulous lower jaw implant stabilised dentures have proved clinically so successful that the indication for this treatment is now being discussed more often with geriatric patients. The aim of this study of edentate subjects was to determine the age-relation of the demand for denture improvement, the risks and feasibility of implant treatment. Sixty four complete denture wearers aged from 42 to 84 years took part in the study. A questionnaire was used to determine the subjective demand for denture improvement. For 33 subjects implants seemed possible. For these patients fear and scepticism concerning implant treatment were specified and quantified. Impaired general health was the most frequent absolute contra-indication for implants; the local oral prerequisites tended to be slightly less favourable in elderly. Older patients were more satisfied with poorly fitting dentures and were less prepared to take trouble to achieve denture improvement. Although scepticism concerning implant treatment was not age-related, patients who were keen for an improvement of their dentures were significantly younger and less sceptical about implants.     

Elders with implant overdentures: a 22-year clinical report

doi: 10.1111/j.1741‐2358.2012.00628.x Elders with implant overdentures: a 22‐year clinical report Objective: To report on the long‐term survival and prosthodontic maintenance of two edentulous adults with mandibular overdentures supported by hydroxyapatite (HA)‐coated implants. Background: Mandibular implant overdentures are a successful treatment option with positive impact on the quality of life of elderly edentulous adults. Long‐term survival of the implants requires continued rigorous prosthodontic maintenance. Clinical report: Two elderly edentulous adults with mandibular overdentures supported by 2 HA‐coated implants were presented for prosthodontic rehabilitation after 22 years of placement. The implants were osseo‐integrated and surviving at presentation based on accepted criteria. The mandibular implant overdentures suffered recurrent loss of retention and stability. Prosthodontic treatment involving the replacement of defective attachment systems and construction of new sets of mandibular implant overdentures opposing complete maxillary dentures is presented. Conclusion: The long‐term survival of mandibular 2‐implant overdentures requires continued prosthodontic maintenance. A conservative approach in the rehabilitation of two older edentulous adults with mandibular 2‐implant overdentures was described including proper selection of attachment systems.     

The Yad Sarah geriatric dental clinic, a different model

Introduction: There are not sufficient dental services for elderly people around the world. Yad Sarah is an Israel‐wide network of volunteers aiding sick, elderly, isolated and housebound people with an array of services aimed at making home care possible. It provides medical and social services to more than 380 000 elderly persons per year and in addition, lends medical equipment free of charge, has day rehabilitation centres, legal aid council for seniors, provides transportation for the disabled, meal deliveries and geriatric dental services. Materials and methods: The latter are equipped with five dental units (one mobile unit) and a dental laboratory. During the 5 years from 2000 to 2004 the dental services provided dental care for 3890 elderly patients with the main clinic located in Jerusalem. Patients pay an average of 70% of the cost price of their dental care, with the difference being subsidised by Yad Sarah. Of the 515 patients who applied for treatment in 2004, 54% possessed natural teeth in both jaws, 28% were fully edentulous, 12% were edentulous in the maxilla and 6% were edentulous in the mandible. Females applied for dental treatment more often than the male population. Older patients (75–101 years old) required oral care at their homes or at old age residences, more frequently than the younger age groups (60–74 years old). Conclusion: Dental treatment was administered by 70 volunteer dental surgeons, two certified dental hygienists and dental hygienist students. The clinical staff was provided with a comprehensive in‐service training in geriatric dentistry during the 3‐year service learning period. A survey in 2004 showed that 83% of the selected patients were satisfied, compared with 14% who were not. The reasons for satisfaction were, mainly, the personal relationship with the attending staff (41%) and the professional ability of the dental team (46%).     

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.     

Screening of edentulous patients in a dental school population using the prosthodontic diagnostic index

doi:10.1111/j.1741‐2358.2009.00317.x
Screening of edentulous patients in a dental school population using the prosthodontic diagnostic index Purpose: The aim of this study was to classify a number of completely or partially edentulous patients who attended undergraduate clinics at the Dental School of Athens using the prosthodontic diagnostic index (PDI) to identify the complexity of the cases treated by the students. Background: There is a scarcity of studies, concerning prosthodontic patients and screening them according to a classification system such as the PDI. Material and methods: The survey was conducted on 181 patients who attended the clinics for treatment. The PDI categorised the patients into four classes (Class I–IV) according to the severity of certain diagnostic findings. Results: From the 110 completely edentulous patients, 27 patients were in Class I, 21 in Class II, 15 in Class III and 47 in Class IV. From the 71 partially edentulous patients, two were in Class I, 17 in Class II, 29 in Class III and 23 in Class IV. Conclusion: Our results showed that the majority of patients were categorised in Class III (partially edentulous) and IV (completely edentulous). This indicates the need to introduce a proper screening tool, such as the PDIs, during the initial examination, to achieve a successful treatment.     

The orodental status of a group of elderly in-patients: a preliminary assessment

Objective: To provide a preliminary assessment of the orodental status and dental treatment requirements of a group of elderly in-patients. Design: Cross-sectional. Setting: Acute Care of the Elderly and Stroke Rehabilitation units at teaching hospitals in Merseyside. Subject: 150 patients aged 58 to 94 years, in which a history could be validated at interview. Intervention: Questionnaire administered by dentist and clinical examination. Main outcome measures: Registration with a dentist, prosthetic status and difficulties with dentures, denture hygiene and identification marking, dental treatment needs and evidence of mucosal pathology. Results: Only 27% of patients claimed registration with a dentist. Three quarters of the patients were edentulous and 66 patients wore full dentures; 18 had no prostheses. Difficulties were experienced by one quarter of patients with upper dentures, compared with a half of lower denture wearers. Of the dentures available for inspection, 61 % had removable soft debris, 66% were left out at night and 75% were cleaned by the patient, whilst on the ward. No dentures had evidence of identification marking. Of the 39 partially dentate patients, 75% required interventive dental treatment. Denture stomatitis was diagnosed in 29% of patients and 19 had evidence of benign mucosal pathology. Conclusions: The orodental status of this group of elderly in-patients was poor, with a high proportion being edentulous. Few were registered with a dentist and denture hygiene was inadequate. Lack of identification marking is a matter of concern. Closer liaison between hospital staff responsible for elderly in-patients is required, to improve the orodental health and quality of life of this medically compromised group of patients.     

Implant overdentures for edentulous elders: study of patient preference

Background: Studies show that elders wearing implant overdentures have improved nutrition and quality of life. However, upfront costs of this therapy are high, and the income of elderly edentulous populations is low. Objectives: This study was designed (i) to measure the preferences of edentulous patients for mandibular two‐implant overdentures using Willingness‐To‐Pay (WTP) and Willingness‐To‐Accept (WTA), (ii) to assess the effect of long‐term financing on WTP and (iii) to assess the desired role of health care plans in financing dental prostheses. Methods: Edentulous elders (68–79 years; n = 36) wearing maxillary dentures and either a mandibular conventional denture (CD, n = 13) or a two‐implant overdenture with ball attachments (IOD, n = 23) participated in this study. All had received their prostheses 2 years previously, as part of a randomised clinical trial. A three‐part questionnaire was completed during a 20‐min interview with a trained researcher. Results: Forty‐six per cent (6/13) of the CD wearers and 70% (16/23) of the IOD wearers were willing to pay three times more than the current cost of conventional dentures for implant prostheses. These percentages were increased to 77% (CD) and 96% (IOD) if participants could pay for implant overdentures in monthly instalments. Eighty‐six per cent (31/36) of all participants in both groups (21/23 IOD; 10/13 CD) thought that the government should cover at least some of the cost of implant overdentures. Conclusions: This study shows that, the majority of elderly edentate individuals who have not experienced mandibular two‐implant overdenture therapy are willing to pay the cost, particularly when payment can be made in monthly instalments.     

Impact of Human Genome Project on treatment of frail and edentulous patients

Objective: Because of ongoing increases in life expectancy and deferment of edentulousness to older age, dentists are facing a different challenge to satisfy elderly denture wearers with a higher prevalence of chronic diseases. This discussion introduces the Human Genome databases as novel and powerful resources to re‐examine the core problems experienced by frail and edentulous patients. Background: Recent studies demonstrated that mandibular implant overdentures do not necessarily increase masticatory function, perception and satisfaction in denture wearers with adequate edentulous residual ridges. It has been demonstrated that the rate of edentulous residual ridge resorption significantly varies among individuals. The prognosis and cost‐effectiveness of denture treatment, with or without implants, may largely depend on how the edentulous ridge is maintained. However, reliable clinical methods permitting dentists to predict the long‐term health of the edentulous residual ridge are lacking. Materials and methods: With the completion of the Human Genome Project, the genomic sequence database from this multinational consortium will provide a unique resource to determine the genetic basis of similarity and diversity of humans. Results: One base pair in every 100 to 300 base pairs of the genome sequence varies among humans, suggesting that genetic diagnosis using the single nucleotide polymorphisms (SNPs) may provide a novel opportunity to differentiate our edentulous patients. Conclusions: Future dental service for the elderly will require a personalized care paradigm, using highly sensitive diagnostic technology such as SNP genomic analysis, for recommending the treatment with greatest potential benefit.     

Comparison of mandibular bone mineral density in osteoporotic, osteopenic and normal elderly edentulous subjects measured by the dual-energy X-ray absorptiometry technique

doi: 10.1111/j.1741‐2358.2012.00625.x Comparison of mandibular bone mineral density in osteoporotic, osteopenic and normal elderly edentulous subjects measured by the dual‐energy X‐ray absorptiometry technique Objective: The aim of this study was to compare the mandibular body bone mineral density according to bone mineral density status of spine and femur measured by dual‐energy X‐ray absorptiometry (DXA) technique in elderly edentulous individuals. Background: One of the factors that affect the survival rate of implants is bone mineral density (BMD) of the jaws. Materials and methods: Fifty edentulous elderly patients’ (27 women and 23 men) spine, femur and the mandibular body BMDs were measured using DXA technique. BMD scans of the AP lumbar spine (L2–L3) and femur were classified using World Health Organisation criteria for bone mass. Results: There was a statistically significant difference between the normal femur group’s–osteoporosis group’s mandibular body BMD (p = 0.001) and femoral osteopaenia group’s–osteoporosis group’s mandibular body BMD (p < 0.001). The femoral osteoporosis group’s mandibular body BMDs were lower than those of both the normal femoral and the femoral osteopaenia group subjects’. Conclusion: Classification of edentulous mandibles according to low and high bone mineral densities is a problem in implant dentistry. The results of this study demonstrated that femoral bone mineral density status may be used to provide preliminary information about the bone mineral density of the mandibular body region in elderly edentulous subjects.     

Oral health status in a group of the elderly population residing at home

doi: 10.1111/j.1741‐2358.2011.00556.x Oral health status in a group of the elderly population residing at home Objectives: To determine the oral health status and treatment needs of subjects aged 65 years and older residing in different districts of Ankara. Materials and methods: A total of 1300 patients, 751 females and 549 males, age 65 and over with a mean age of 72.8 ± 6.34 were included in this study. The subjects were visited at home and toothbrushing habits, visiting the dentist, tooth loss, denture needs were questioned and body mass index values were recorded. Results: 52.5% of the subjects were completely edentulous, 83.3% subjects reported wearing a removable denture. Females had a higher total tooth loss frequency when compared to males (p < 0.05). Total tooth loss between 65 and 69 ages was 47.3%, and increased to 62.4% among those aged 75 and over (p < 0.05). 16.2% of the subjects had not visited a dentist in the last 10 years, and only 3% visited a dentist for control check‐ups; no gender‐based difference was observed as to the frequency of dental visits (P > 0.05). No significant relationship was found between tooth loss and BMI values (P > 0.05). 46.3% of the subjects had chewing problems. Conclusions: The subjects included in this study showed high tooth loss frequency and poor oral hygiene habits. Education regarding maintenance of oral hygiene and regular dental check up should be stressed for the elderly.     

The oral health‐related quality of life in edentulous patients treated with Conventional complete dentures

Objective: To compare the oral health‐related quality of life (OHRQoL) between patients with both maxillary and mandibular complete denture and those with either the maxillary or the mandibular complete denture. Background: Satisfaction of denture wearers can be estimated using the OHRQoL questionnaires like the OHIP‐EDENT and the Geriatric Oral Health Assessment Index (GOHAI). Methods: Two questionnaires were used to compare the OHRQoL between edentulous patients who had conventional removable complete denture on both jaws and those who had on either one of the jaws. Result: The age of the participants ranged from 42 to 75 years, with the mean age of 58 ± 8.12 years. The mean OHIP‐EDENT scores were significantly high among those who wore conventional dentures in both jaws (54.12 ± 5.21), compared with the participants who only had denture either on upper or lower jaw (46.52 ± 7.35). It was noticed that the mean GOHAI score was significantly lower (p < 0.05) among participants who had conventional denture on both upper and lower jaw (28.25 ± 3.67), as compared to those who had conventional denture only on one arch (35.12 ± 2.11). Conclusion: Patients with complete dentures in both jaw (Group I) were less satisfied than patients with single complete denture (Group II). The result obtained in this study shows dissatisfaction with conventional dentures among edentulous patients.     

Evaluation of satisfaction with masticatory efficiency of new conventional complete dentures in edentulous patients--a survey

doi: 10.1111/j.1741‐2358.2012.00634.x Evaluation of satisfaction with Masticatory efficiency of new conventional complete dentures in edentulous patients. A survey Background: Knowing how patients really feel after treatment is, very often, as relevant as the success rate of the conventional dentures and it can even be the measurement of masticatory function. Aim and objectives: This questionnaire survey aimed to analyse the satisfaction level and masticatory efficiency of patients treated with conventional complete dentures. Design and setting: Thirty edentulous patients were considered in the study. Satisfaction level and masticatory efficiency were analysed based on specific questionnaires for edentulous patients and by a likert rating scale from 0 to 5, at three moments: Prior to treatment (edentulous period), after the insertion of the new dentures and at 30–45 days follow‐up. Materials and methods: Thirty patients including 12 male and 18 female patients (mean age 65 years), who voluntarily came for the services. T‐test was applied at three different levels. Results: The rehabilitation with conventional complete dentures produced an improvement (p < 0.05) in satisfaction level and masticatory efficiency. Conclusion: Thus, those patients who were edentulous previously and dissatisfied with their masticatory ability showed improvement after receiving a new set of conventional complete dentures.
