doi:10.1111/j.1741‐2358.2009.00323.x
Assessment of changes in oral health‐related quality of life among patients with complete denture before and 1 month post‐insertion using Geriatric Oral Health Assessment Index Objective: Geriatric Oral Health Assessment Index (GOHAI) is a 12‐item measure of “patient‐reported oral functional problems” intended for use in the assessment of the effectiveness of dental treatment. Design and Setting: As there is scanty literature available on GOHAI in the Indian population, the present study was undertaken to assess the changes in GOHAI before and 1 month after placement of dentures in completely edentulous patients reporting to a dental hospital at Indore, India. Measurements: The GOHAI questionnaire was completed by the examiner who interviewed the patients (n = 35) before placement of complete dentures and 1 month later. Mean, median values were calculated and the data were analysed using Wilcoxon signed‐rank test. Results: When overall mean was considered, the GOHAI scores increased from 27.48 to 30.19 (p = 0.002; highly significant). Conclusion: Patients reported improvement in functional changes after placement of complete dentures.     

Impact of new prostheses on the oral health related quality of life of edentulous patients

Objective: A study was conducted to evaluate the impact of the placement of complete dentures by using the Global Oral Health Assessment Index (GOHAI). Background: Oral health quality of life indicators can be used to evaluate the effects of dental treatments. Material and methods: The 26 participants were treated in a French University Clinic during 2002. They were randomly divided into two groups. Each group received new prostheses, but evaluation of the quality of life was made at different periods [baseline, denture placement (group 1), 6 and 12 weeks (group 2) after placement]. A questionnaire was used to collect information on patient's satisfaction with the previous and new prostheses. Nonparametric tests were used to test the relationships between patients’ satisfaction or baseline data and GOHAI variations with time as well as to compare mean values of GOHAI within each group. Results: At baseline, the impact of oral health problems was apparent; the mean GOHAI‐Add score was 45.8 (10.2). Six weeks after placement of the new denture, there was no difference in GOHAI scores compared with the initial assessment. An improvement in GOHAI score was observed 12 weeks after the participants received their new dentures (p < 0.05). Change in GOHAI‐Add scores was negatively correlated with the initial GOHAI‐Add score. Patients who preferred the new prosthesis enjoyed a positive change in GOHAI scores (p < 0.001). There was a relationship between participants’ satisfaction with the new dentures and change in GOHAI scores (p < 0.05). Conclusion: The GOHAI can be used to evaluate needs for and effect of the making of new complete dentures.     

Elderly complete denture wearers: a social approach to tooth loss

doi: 10.1111/j.1741‐2358.2011.00550.x Elderly complete denture wearers: a social approach to tooth loss Objectives: To correlate emotional reactions to tooth loss with denture satisfaction attributes in elderly complete denture wearers. Background: Total tooth loss is a serious life event, and poor oral health has an impact on daily life. Edentulism treated by rehabilitation with dentures can have a positive effect on patients’ self‐image and social behaviour. Methods: A group of 80 edentulous subjects undergoing routine prosthetic care in a Greek Department of Prosthetic Dentistry were interviewed using two structured questionnaires. The first questionnaire explored reactions to tooth loss, whereas the second measured their subjective experience of complete dentures. The responses to both questionnaires were compared using the statistical package spss v.17. Results: The results showed significant correlation between aspects of tooth loss experience and complete denture satisfaction. Despite the fact that a substantial proportion of patients were satisfied with their complete dentures, some patients experienced increased social and psychological problems related to their edentulousness and the wearing of complete dentures. The aesthetic and functional aspects of complete dentures affected both patients’ social behaviour and self‐confidence. Conclusions: Total tooth loss was not only reflected in patient’s social behaviour and self‐image, but it had a complex and multifaceted impact on satisfaction from complete dentures.     

Clinical evaluation of three denture cushion adhesives by complete denture wearers

doi: 10.1111/j.1741‐2358.2010.436.x Clinical evaluation of three denture cushion adhesives by complete denture wearers Objective: The aim of this study was the clinical evaluation of three denture cushion adhesives and whether the results were correlated to Kapur Index for denture‐supporting tissues. Background: Various types of denture adhesives are used among denture patients. However, information on the clinical behaviour of denture cushions is limited. Materials and methods: Thirty edentulous patients had their denture‐supporting tissues scored by Kapur Index and their old dentures replaced. They received three brands of denture cushion adhesives (Fittydent^®, Protefix^® and Seabond^®) and were instructed to use them in a sequence according to the group they were randomly assigned to. Each brand of adhesive was used for 48 h on the lower denture according to the manufacturer’s suggestions. After each brand was used, participants spent 24 h without applying any sort of adhesive. Finally, a questionnaire evaluating and comparing the performance of each brand was filled out. Results: Denture adhesives generally improved patient satisfaction and masticatory ability, especially in participants with poor Kapur Index and those who reported a poor retention of their old dentures. Conclusion: Fittydent^® was the most preferred adhesive, showing the best retention and the longest duration of its effect, but also reported as difficult to remove from the denture‐bearing area.     

Effervescent tablets and ultrasonic devices against Candida and mutans streptococci in denture biofilm

doi: 10.1111/j.1741‐2358.2010.00378.x Effervescent tablets and ultrasonic devices against Candida and mutans streptococci in denture biofilm Objective: To evaluate the antimicrobial action of effervescent tablets and ultrasound on Candida spp. and mutans streptococci from denture biofilm. Background: It is not uncommon for edentulous patients to be elderly and find it difficult to brush their dentures. Hence, auxiliary methods are required for cleansing dentures as well as treating oral infections. Materials and methods: Seventy‐seven complete denture wearers were randomly assigned into four groups: (A) Brushing with water (control); (B) Effervescent tablets; (C) Ultrasonic device (Ultrasonic Cleaner, model 2840 D); (D) Effervescent tablets and ultrasonic device. All groups brushed their dentures with a specific brush and water, three times a day, before applying their treatments. Denture biofilm was collected at baseline and after 21 days. The samples were collected by brushing the dentures with saline and the detached microbial cells were quantified by plating. Counts [log (CFU+1) ml^?1] of total aerobes, Candida spp. and mutans streptococci were compared by one‐way anova or Kruskal–Wallis test (α = 0.05). Results: No significant difference was found among the methods from C. albicans (p = 0.76), C. tropicalis (p = 0.94) and C. glabrata (p = 0.80). Lower counts were found for methods B and D when compared with the other methods against mutans streptococci (p < 0.001). Method B showed lower total aerobic counts than A, whereas C and D showed intermediate results (p = 0.011). Conclusion: The effervescent tablets significantly reduced mutans streptococci and total aerobes from denture biofilm. However, they was not as effective against C. albicans. Ultrasonic cleansing presented a discrete antimicrobial effect and was less effective than the tablets for complete denture disinfection.     

Insertion and follow‐up of complete dentures: a literature review

Gerodontology 2010; 00; doi: 10.1111/j.1741‐2358.2010.00368.x Insertion and follow‐up of complete dentures: a literature review Objective: The aim of this study was to present the importance of clinical procedures related to insertion and follow‐up of complete dentures in elderly patients. Materials and Methods: The success of rehabilitation with complete dentures results from the accuracy of clinical and laboratorial procedures that makes the denture insertion an important step of treatment. Conclusion: The follow‐up and professional maintenance of function and hygiene facilitates long‐term efficiency.     

Survival analysis of mandibular complete dentures with acrylic‐based resilient liners

doi: 10.1111/j.1741‐2358.2012.00658.x Survival analysis of mandibular complete dentures with acrylic‐based resilient liners Objective: The purpose of this long‐term randomised controlled trial was to compare the longevity of dentures constructed using a conventional acrylic resin (CAR) to that of dentures constructed using an acrylic‐based resilient liner (ARL). Materials and methods: The follow‐up study was essentially carried out by annual telephone calls to each of the 67 participants. The Kaplan–Meier method and life‐table analysis were used for univariate analyses. The Cox proportional‐hazards test was used as a final model for statistically adjusting predictor variables such as sex, clinician type, mandibular denture type and age at denture delivery. Results: The denture type was likely to affect the survival time of the dentures, while the sex and clinician type were not. The group using acrylic‐based resilient denture liners had twice the risk of having shorter denture‐survival times than those using conventional acrylic resin dentures. Younger participants were likely to have a reduced risk of having shorter denture‐survival times than older participants. Conclusion: We conclude that mandibular complete dentures constructed using ARL are twice as likely as dentures constructed using CAR to have shorter denture survival times, mainly because of material deterioration.     

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.     

Effects of denture maintenance on satisfaction levels of Taiwanese elderly using removable partial dentures: a pilot study

doi: 10.1111/j.1741‐2358.2011.00500.x
Effects of denture maintenance on satisfaction levels of Taiwanese elderly using removable partial dentures: a pilot study Objective: The aim of this study was to evaluate the correlation between patient satisfaction with removable partial dentures and denture maintenance by patients, including regular application of denture adhesives and cleansers. Background: The success of removable partial dentures depends on patient satisfaction with dentures and their regular denture maintenance. Materials and methods: Demographic information, the Oral Impacts on Daily Performance (OIDP) indicator and details of denture maintenance (including the use of denture cleansers and adhesives) were collected from 193 (41.5% men and 58.5% women) participants by using questionnaires. A dentist performed oral examinations to evaluate denture function according to the OIDP items photographically and recorded the number of remaining teeth and Kennedy’s classification. Results: Most participants were satisfied with their removable partial dentures and tended to have higher satisfaction levels than the dentist’s estimation. Further, those using denture adhesives and cleansers had higher satisfaction levels than those not using such denture maintenance. Conclusions: Appropriate education regarding denture use is important because regular denture maintenance by patients affects their degree of satisfaction with dentures, as well as the dentist’s skill and the patient’s oral condition. Dentists could use this information to predict the potential success of dentures.     

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.     

Tooth loss, denture wearing and associated factors among an elderly institutionalised Brazilian population

Objective: This cross‐sectional study assessed the prevalence and extent of tooth loss as well as denture wear and associated factors in institutionalised elderly in Brazil. Background: There is scarcity of research in Brazil concerning geriatric oral health issues. Material and methods: A sample of 335 individuals over 60 years of age, representative of the institutionalised elderly from Belo Horizonte, Brazil, were selected through a stratified sampling strategy. Data were collected from structured questionnaires, reviews of medical records and intra‐oral examinations. Results: Edentulousness was observed in 74.9% of the elderly and was related to age, years of study, income, length of institutionalisation, systemic diseases and mini‐mental score. Among the dentate subjects, 17.9% possessed 20 or more teeth. Approximately half the edentulous elderly (42.6%) and most of the partially dentate subjects (66.7%) did not wear dentures. The multivariate analysis showed that subjects that wear dentures were more likely to be female, possess higher incomes, be more functionally independent and married. Furthermore, the odds of wearing dentures among the elderly who had lost 13–32 teeth were 9.11 times higher than those who had lost up to 12 teeth. Conclusion: Tooth loss is highly prevalent in this institutionalised Brazilian population, and the prevalence of denture wear is low. The extent of tooth loss, income, functional status and marital status are important predictors for denture wear. The development of an oral health programme for these individuals should assist in their rehabilitation needs and promote in‐home care or safe transport for the elderly to a health care location.     

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.     

Complete denture wearing and fractures among edentulous patients treated in university clinics

doi: 10.1111/j.1741‐2358.2011.00551.x
Complete denture wearing and fractures among edentulous patients treated in university clinics Objective: The prevalence of wearing and fracture of complete dentures was evaluated among edentulous patients treated in two dental schools in Brazil. Background: Acceptance and wearing of complete dentures are related to adaptive behaviour of edentulous patients. However, one reason that could interfere with the wearing dentures is their potential to fracture, which is still a common complication in denture rehabilitation practice. Material and methods: Two hundred and twenty‐four edentulous patients rehabilitated with complete dentures from 2000 to 2005 in Araçatuba and Araraquara Dental School, University of State of São Paulo, were assessed in 2006 and 2007 to answer a questionnaire about wearing and fracture of their dentures. Statistical analysis were performed using Epi Info software and chi‐squared test to compare maxillary and mandibular data (α = 0.05). Results: Almost 26% of the patients did not wear their dentures, and among the remainder, the majority wore the maxillary denture. About 30% of the dentures were fractured, with higher prevalence in the maxillary arch (p = 0.003). Conclusions: Discontinuation of wearing dentures was quite high, especially considering the treatment which was carried out in university clinics. Prevalence of fractures was also high, greater for the maxillary denture, and was one of the main reasons for non‐wearing of complete dentures.     

Influence of psychological factors on the acceptance of complete dentures

Objectives: To assess the influence of psychological factors on the acceptance of complete dentures in a population wearing dentures judged to be clinically satisfactory. Design: Subjects were asked to complete personality profiles and also to rate their dentures using a denture satisfaction questionnaire. Setting: The survey was conducted in the prosthetics clinic of a teaching hospital. Subjects: Patients were selected from those who had new complete dentures constructed in the department within the previous two years. Intervention and main outcome measures : The personality inventory was a self‐administered questionnaire comprising 240 items covering the five domains of personality. Denture satisfaction was scored on a nine item scale with four Likert type responses to each. Results: A group of 16% consistently complained about their dentures. Statistical analysis showed that personality factors especially Neuroticism had a significant relationship with denture satisfaction. Conclusion: Psychological factors significantly influence denture satisfaction and profiles may provide useful in predicting potential difficult denture wearers.     

Knowledge of prosthodontic treatment among denture-wearers and non-denture-wearers attending a dental institute in India: a survey report

Objective: Knowledge of subjects regarding prosthodontic treatment may play a role in their acceptance of the prostheses. The purpose of this survey was to assess the knowledge of prosthodontic treatment among the denture‐wearers and non‐denture‐wearers reporting to the Institute of Dental Sciences, Belgaum. Methods: A self‐designed closed‐ended questionnaire containing 14 questions was designed. Four‐hundred and nineteen subjects aged between 25 and 65 years were surveyed over a period of 2 months. Collected data were statistically analysed using chi‐squared test at a significance level of p < 0.05. Results: From the 419 subjects surveyed, 140 subjects (33.4%) were dentate and 279 subjects (66.6%) were edentulous either in the maxillary, mandibular or both arches. Among the 279 edentulous subjects, 143 (51.3%) did not use any kind of prosthesis. There was a statistically significant difference in knowledge regarding the replacement of teeth by artificial means, the number of visits required for the provision of a complete denture, problems with dentures among subjects using and not using them (p < 0.001) whereas no significant difference was found among the subjects regarding aesthetics with dentures and socializing with friends. Conclusion: Attempts should be made to raise the level of knowledge of both denture‐wearers and non‐denture‐wearers reporting to the Institute for any dental treatment.     

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.     

In vivo biofilm formation on a soft denture liner in elderly patients with controlled diabetes

doi: 10.1111/j.1741‐2358.2010.00428.x In vivo biofilm formation on a soft denture liner in elderly patients with controlled diabetes Objectives: This in vivo study evaluated the influence of controlled diabetes on biofilm formation on a soft denture liner in elderly patients. Background: Soft denture lining materials are more susceptible to microbial colonisation than denture base acrylic resins. Especially in the elderly, several predisposing factors may accumulate leading to an increased probability of biofilm development that may result in candidiasis, a significant clinical oral disease. Materials and methods: Volunteers wearing complete dentures were divided into two groups (n = 20): diabetic patients with controlled glycaemia, and healthy patients. In both groups, a silicone‐based soft liner was placed in a recess created at the base of the maxillary dentures. Subjects cleaned the prosthesis three times a day. Biofilm formed on the liner was quantified at various time points (baseline, two, four and six weeks). Data were analysed by two‐way repeated measures anova and Tukey’s test (α = 0.05). Results: There was no statistical difference in biofilm formation for any of the time points between controlled diabetes patients and healthy patients. Conclusion: The results suggest that the control of diabetes in elderly patients provides the same levels of biofilm formation when compared to healthy individuals.     

Complete denture hygiene and nocturnal wearing habits among patients attending the Prosthodontic Department in a Dental University in Brazil

Gerodontology 2010; doi: 10.1111/j.1741‐2358.2010.00369.x Complete denture hygiene and nocturnal wearing habits among patients attending the Prosthodontic Department in a Dental University in Brazil Objective: The aim of this study was to evaluate the overnight wearing and cleaning habits of complete denture wearers. Background: Successful complete denture treatment can be achieved when the patients are motivated and aware of appropriate denture wear and hygiene. Materials and methods: A sample of 224 complete denture wearers (162 women) aged 37–89 years was studied. Inclusion criteria comprised edentulous subjects who had received their new complete dentures between 2000 and 2005 in the Dental Clinic of the Araçatuba and Araraquara Dental School, São Paulo State University. Ethical approval was sought and granted. Subjects were interviewed using questions related to overnight denture wearing and denture cleaning habits. Possible statistical relationships among some of items were analysed by the chi‐square test at 5% significance level. Results: Of the patients, 55.8% removed their dentures during the overnight period and 88% did this every day. Among them, 66.4% removed both dentures. Most of the patients used brushing with toothpaste (105 patients – 46.87%) as a cleaning method. More than a half of the subjects (63.4%) showed biofilm and calculus on their dentures. Conclusion: The patients need instructions and motivation concerning denture hygienic and denture removal overnight.     

Tooth loss, the wearing of dentures and associated factors in Sri Lankan older individuals

Objective: To determine tooth loss, wearing of dentures and associated factors in older individuals from Sri Lanka. Design: A cross‐sectional survey where the data were collected by means of an oral examination and an interviewer administered questionnaire. Setting: Negambo within the Gampaha district of Sri Lanka. Subjects: A total of 630 subjects who were aged 60 years and above. Results: Only 11 subjects had all 32 teeth and 17% were edentulous. Age, gender and level of income were significantly associated with the number of missing teeth. Of those with missing teeth, 22% wore dentures. Only 16% of the non‐denture wearers perceived a need for dentures. Among the non‐denture wearers who perceived a need for dentures, a majority had cited ‘cost’ as the main barrier for obtaining dentures. Logistic regression analysis revealed that age, gender, levels of income and education and missing teeth were significant predictors of wearing of dentures. Conclusions: Knowledge of factors that influence tooth loss and wearing of dentures may have implications for oral health care planners in the provision and delivery of oral health services to the older individuals.
