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.     

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.     

The teaching of prosthodontic care for older people: a non-rote philosophy

This essay complements that de Baat et al¹ in the last issue with emphasis on the importance of the variability between individual older people. The consequent need for an open minded approach towards planning Prosthodontics is discussed, based on each patient's motivation for aesthetics, function, comfort and self esteem. Both functional expectations and motivation to learn effective health behaviour vary widely, and evaluation of both is essential for realistic planning because further tooth loss and the need for partial dentures occur so frequently. The consequent variation in plans raises the question – which are the strategic teeth to maintain a stable dental occlusion or a future tooth stabilised denture? For undergraduates this demands a non-rote approach to learning.     

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.     

Non‐surgical treatment of gingival overgrowth induced by nifedipine: a case report on an elderly patient

doi:10.1111/j.1741‐2358.2009.00273.x
Non‐surgical treatment of gingival overgrowth induced by nifedipine: a case report on an elderly patient Drug‐induced gingival overgrowth (DIGO) is a significant problem for periodontologists and this side effect is frequently associated with three particular drugs: phenytoin, cyclosporin A and nifedipine. A case report of gingival overgrowth induced by nifedipine in an elderly patient treated with non‐surgical periodontal therapy is described. A 75‐year‐old male with generalised gingival overgrowth reported the problem of oral malodour and significant gingival bleeding. The medical history revealed a controlled hypertensive state and Cerebral Vascular Accident (CVA) 3 years prior to consultation. The diagnosis was gingival overgrowth associated with nifedipine, no other risk factors being identified. The patient had been taking nifedipine for 18 months, but after the consultation with the patient’s doctor, nifedipine was suspended, as the hypertension was controlled. Treatment consisted of meticulous oral hygiene instruction, scaling, root surface instrumentation and prophylaxis. Six months after the first intervention, clinical parameters revealed a significant improvement with a considerable reduction in gingival overgrowth, demonstrating the effect of non‐surgical periodontal therapy in severe cases of gingival overgrowth. Non‐surgical treatment of DIGO is a far less invasive technique than surgical approaches and has demonstrated an impressively positive treatment response. It should therefore be considered as a first treatment option for DIGO.     

Use of resin‐bonded extracoronal attachments with removable partial denture: case report

doi:10.1111/j.1741‐2358.2009.00298.x
Use of resin‐bonded extracoronal attachments with removable partial denture: case report Introduction: Resin‐bonded extracoronal attachments may be indicated for the abutment teeth of removable partial dentures, especially for anterior teeth when a cingulum rest must be provided. This type of treatment has a series of advantages such as minimal tooth reduction, supragingival margins, favourable stress distribution, and improved aesthetic appearance. Objective: To report a clinical case of oral rehabilitation using a combination of resin‐bonded extracoronal attachments joined by a Dolder bar with a removable partial denture. Case report: A 60‐year‐old male patient with only the canines in the maxillary arch was restored with a combination of resin‐bonded extracoronal attachments joined by a Dolder bar and a removable partial denture. Conclusion: Dentures with resin‐bonded extracoronal attachments can have a number of advantages over traditional clasp‐retained removable partial dentures.     

Partial edentulism and removable partial denture design in a dental school population: a survey in Greece

Gerodontology 2011; doi: 10.1111/j.1741‐2358.2010.00382.x Partial edentulism and removable partial denture design in a dental school population: a survey in Greece Objectives: To investigate the pattern of partial edentulism and the most frequent designs of cobalt‐chromium removable partial dentures (RPDs), constructed at the Dental School of Athens, Greece. Methods and materials: Five hundred and fifty‐three patients, between 42 and 81 years old, mostly males, treated by undergraduate dental students, were included. The survey was based on visual evaluation of master casts and work authorisation to dental technicians. Aspects examined were: Kennedy Classification, modification areas, major connectors, clasping, placement of rest seats and indirect retention. Results: Kennedy Class I was the most common encountered in the maxilla (50.5%) and in the mandible (70%). The most frequent major connectors were the lingual bar (92.6%) and the U‐shaped palatal strap (54%). The most common clasp was the Roach (69.2%) in Class I and Class II. In Class III and IV, the most common was the occlusally approaching clasp (55% and 70%). The most frequent location of the rest was mesial of abutment teeth. On the average, 39.5% of Class I RPDs and 58.6% of Class II RPDs had indirect retainers. Conclusion: A combination of the two major philosophies of RPD design (biomechanical and hygienic) was evident in the RPDs examined in our study.     

First-time dental care and the most recent dental treatment in relation to utilisation of dental services among dentate elderly patients in Lithuania

Objectives: To describe the initial dental treatments of Lithuanian dentate elderly patients and the content of the most recent treatment in relation to their dentist‐visiting behaviour. Materials and methods: A cross‐sectional questionnaire study was carried out at two public dental offices in Kédainiai, Lithuania, among dentate patients aged 60+ years. A self‐administered questionnaire covered first‐time dental care, the most recent dental treatment, check‐up behaviour, interval since the most recent dental visit, and number of teeth. Age, gender and education served as background information. Statistical evaluation was by chi‐squared test, anova and logistic regression for odds ratio (OR). Results: In all, 174 dentate elderly responded, mean age being 69.2 (SD = 6.6) years. The mean age at the first visit was 16.3 years [95% confidence interval (CI) 14.9–17.6]. Regular dental check‐ups were reported by 30%, and 36% had visited a dentist within the past 12 months. As to the content of the most recent treatment, 78% of the elderly reported filling therapy, 50% endodontics, 48% tooth extraction, 21% radiography, 10% cleaning or scaling and 6% polishing of fillings. Those going for check‐ups were more likely to report diagnostic (OR 1.9; 95% CI 1.1–2.8; p = 0.01) and preventive (OR 4.8; 95% CI 2.5–9.0; p = 0.002) treatment when analysed by a logistic regression model, controlling for age, gender, education and number of teeth. Conclusions: Check‐up‐orientated utilisation of dental services should be encouraged among the Lithuanian elderly. Dentists and health officials should place greater emphasis on prevention.     

Attitudes and usage of denture adhesives by complete denture wearers: a survey in Greece and the Netherlands

doi: 10.1111/j.1741‐2358.2011.00566.x
Attitudes and usage of denture adhesives by complete denture wearers: a survey in Greece and the Netherlands Objective: To explore whether there are differences in usage of and attitudes towards denture adhesives among patients in two countries. Background: There are no multi‐country surveys concerning usage of and attitudes towards denture adhesives from complete denture wearers. Materials and methods: The survey took place in Greece and the Netherlands with a sample of 284 and 165 consecutive complete denture wearers, respectively, by using a 9‐item prepared questionnaire. Statistical analysis relied on chi‐square test at α = 0.05. Results: In this survey, 26 and 20% of Greek and Dutch patients, respectively, had tried denture adhesive, but only 27% of them in Greece as well as in the Netherlands currently used it; 49% of the Greek and 45% of the Dutch participants rated the overall performance of adhesives as good. Between the two populations, no differences were identified in a majority of the research variables, except where 27% of Greeks answered that they did not know the existence of denture adhesives compared to none of the Dutch patients and when 90% of the Dutch contrary to 70% of Greeks reported that they did not need denture adhesives as they could manage their dentures well. Conclusion: The usage of and attitudes towards denture adhesives between the Greek and Dutch sample were similar with only two exceptions concerning the knowledge of existence and the need of using denture adhesives.     

Association between dental health behaviours, mental/physical function and self-feeding ability among the elderly: a cross-sectional survey

Objectives : The aim of this study was to determine the association between dental health behaviour, mental/physical function and self‐feeding ability among the elderly. Subjects : A total of 414 elderly dental patients aged 65 years and older participated in this study. Methods : A survey was carried out for three years and seven months starting in January 1998 at the Chubu National Hospital. The patients or their carers were examined/interviewed about the severity of senile dementia, dental health behaviour, ability to rinse their mouths, ability to manage dentures, and ability to sit at a table during meals. To assess the association with self‐feeding ability among the elderly, cut‐offs were given for these variables, and then the odds ratios were calculated. Results : The strongest association to self‐feeding ability was marked by inability to rinse their own mouth, followed by inability to manage dentures, inability to sit at a table during meals, severe senile dementia and less frequency of toothbrushing. Conclusion : Elderly who have lost the feeding ability often could not maintain their dental health by themselves. Carers must provide not only a feeding service with acknowledgement of aspiration but oral care to prevent dental disease and fatal pneumonia in the elderly.     

Radiographic evaluation of alveolar ridge heights of dentate and edentulous patients

doi: 10.1111/j.1741‐2358.2010.00391.x Radiographic evaluation of alveolar ridge heights of dentate and edentulous patients Objective: To evaluate the reduction of residual alveolar ridge height on panoramic radiographs and the differences between denture wearers and non‐denture wearers. Materials and methods: The study consisted of 147 individuals (74 men and 73 women) [50 were denture wearers and 50 non‐denture wearers (examination groups) and 47 of them were dentate (control group)]. Individuals having diseases impacting on bone were excluded. Vertical measurements were made at 15 sites (central incisors, first premolars and molars at the left and right of both jaws and the distance between the zygoma/orbit). MANOVA (multi‐variate analysis of variation) was used for the statistical analysis of the results. Results: There were significant differences between the alveolar ridge heights of dentate and edentulous groups (p < 0.001). Between the denture wearer and the non‐denture wearer groups, there was significant difference in the lower jaw (p < 0.001), but no significant difference in the upper jaw (p = 0.635). There were also differences between men and women (p < 0.005) and upper and lower jaws at every measurement sites (p < 0.01). Conclusion: Reduction in residual alveolar ridge height was in close relation with gender, denture usage and edentulousness.     

Knowledge and attitude of elderly persons towards dental implants

doi: 10.1111/j.1741‐2358.2011.00586.x Knowledge and attitude of elderly persons towards dental implants Background: Despite their unrivalled place in restorative treatment, dental implants are still scarcely used in elderly patients. Introduction: The aim of this survey was therefore to identify potential barriers for accepting an implant treatment. Materials and methods: Participants were recruited from a geriatric hospital, two long‐term‐care facilities and a private clinic. The final study sample comprised 92 persons, 61 women and 31 men with an average age of 81.2 ± 8.0 years. In a semi‐structured interview, the participants’ knowledge of implants and attitude towards a hypothetical treatment with dental implants were evaluated. Results: Twenty‐seven participants had never heard of dental implants, and another 13 participants could not describe them. The strongest apprehensions against implants were cost, lack of perceived necessity and old age. Univariate and multiple linear regression analysis identified being women, type and quality of denture, having little knowledge on implants and being hospitalised as the risk factors for refusing implants. However, old age as such was not associated with a negative attitude. Conclusion: The acceptance of dental implants in the elderly population might be increased by providing further information and promoting oral health in general. Regardless of the age, dental implants should be placed when patients are still in good health and live independently.     

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.     

Oral lesions in elderly population: a biopsy survey using 2250 histopathological records

Objective: To perform an oral biopsy survey focused on the incidence of oral lesions in Brazilian elderly patients. Methods: A total of 17 329 oral biopsy records were analysed and divided into two age groups: elderly patients, ≥60 years old; and non‐elderly patients, <60 years old. Information about sex, race, age and histopathological diagnosis (categorised in non‐neoplastic and neoplastic lesions) was collected. Differences of diagnosis incidence were tested by comparison between two proportions (binomial test). Results: The incidence of epithelial malignant neoplasms and pre‐malignant lesions in the elderly group was higher than non‐elderly group, as well as autoimmune diseases and salivary gland tumours. The three most prevalent lesions in the elderly group were inflammatory fibrous hyperplasia, squamous cell carcinoma, and fibroma. Conclusion: The distribution of oral diseases using biopsies allows greater accuracy in data about oral health of elderly patients, especially when considering malignant and pre‐malignant lesions.     

A 3-year longitudinal study of quality-of-life outcomes of elderly patients with implant- and tooth-supported fixed partial dentures in posterior dental regions

doi: 10.1111/j.1741‐2358.2011.00592.x
A 3‐year longitudinal study of quality‐of‐life outcomes of elderly patients with implant‐ and tooth‐supported fixed partial dentures in posterior dental regions Background: Clinical studies have mainly been focused on oral health‐related quality‐of‐life (OHRQoL) outcomes of removable dentures. Objective: To evaluate therapy of elderly patients with implant‐supported fixed partial dentures (IFPD) and tooth‐supported fixed partial dentures (FPD) in the posterior dental regions. Patients and methods: The OHIP49 was used to measure OHRQoL in 64 patients with IFPD and 38 patients with FPD, before, 3 weeks and 3 years after rehabilitation. A control group (CG) consisted of 62 individuals. Results: The Oral Health Impact Profile questionnaire (OHIP) follow‐up scores of the patients with FPD and the patients with IFPD were significantly smaller in comparison with the baseline scores (p < 0.01). The OHIP scores were further reduced at the 3‐year follow‐up. The patients with IFPD had significantly higher scores than the patients with FPD and the CG at the baseline and at the follow‐ups. In the patients with FPD, both age groups (≤60 and >60) showed equal improvement of the OHRQoL. In the IFPD group, patients older than 60 years showed better improvement (p < 0.05). There were no significant differences dependent on gender and antagonistic teeth (p > 0.05). Conclusion: The FPD and the IFPD treatment showed significant improvement of OHRQoL. The FPD treatment improved OHRQoL equally in both age groups, while the IFPD treatment improved OHRQoL better in older patients.     

Predictors of retention among men attending STI clinics in HIV prevention programs and research: a case control study in Pune, India

Background

Retention is critical in HIV prevention programs and clinical research. We studied retention in the three modeled scenarios of primary prevention programs, cohort studies and clinical trials to identify predictors of retention.

Methodology/Principal Findings

Men attending Sexually Transmitted Infection (STI) clinics (n = 10, 801) were followed in a cohort study spanning over a ten year period (1993–2002) in Pune, India. Using pre-set definitions, cases with optimal retention in prevention program (n = 1286), cohort study (n = 940) and clinical trial (n = 896) were identified from this cohort. Equal number of controls matched for age and period of enrollment were selected. A case control analysis using conditional logistic regression was performed.Being employed was a predictor of lower retention in all the three modeled scenarios. Presence of genital ulcer disease (GUD), history of commercial sex work and living away from the family were predictors of lower retention in primary prevention, cohort study and clinical trial models respectively. Alcohol consumption predicted lower retention in cohort study and clinical trial models. Married monogamous men were less likely to be retained in the primary prevention and cohort study models.

Conclusions/Significance

Predicting potential drop-outs among the beneficiaries or research participants at entry point in the prevention programs and research respectively is possible. Suitable interventions might help in optimizing retention. Customized counseling to prepare the clients properly may help in their retention.     

Clinical and microbiological efficacy of three different treatment methods in the management of denture stomatitis

Gerodontology 2010; doi: 10.1111/j.1741‐2358.2009.00354.x
Clinical and microbiological efficacy of three different treatment methods in the management of denture stomatitis Objective: This study evaluated. the effect of mouthrinses and tissue conditioner on the clinical findings and microbial flora of 60 patients with Newton’s type II denture stomatitis (N2DS) Background: Denture stomatitis is a common problem in complete denture wearers. Materials and methods: Sixty patients with N2DS were included in this study and divided into three groups. Two groups of patients were instructed to rinse their mouth with the designated mouthrinses DioxiDent and Corsodyl twice daily for 1 min and to soak their dentures overnight in these solutions for 15 days. For the third group, tissue conditioner was placed in each of 20 patients’ existing maxillary dentures. Patients were evaluated both clinically and microbiologically at baseline and after 15 days. Palatal swabs and smears were taken from each patient before and after treatment and these samples were examined mycologically. The difference between Candida colonisation before and after treatment and the differences between pre‐treatment and post‐treatment clinical findings were assessed. Results: DioxiDent and Corsodyl showed an improvement in palatal inflammation and a decrease in Candida colonisation compared to Visco‐gel. Conclusions: The effectiveness of topical chlorine dioxide and chlorhexidine gluconate in the management of N2DS was demonstrated.     

Assessment of non-response bias in a survey of residential magnetic field exposure in Taiwan

We assessed potential non-response bias in obtaining information on residential extremely low-frequency power frequency magnetic field (MF) in Taiwan. All households occupied by children aged less than 7 years in two study districts, one in an urban town and the other in a rural town, were visited and solicited for on-site measurements in late 2003. The initial response rate was only 32% (33/104, urban) and 60% (61/101, rural). In the same season 1 year later, we performed a second survey of those who declined to be measured at the initial survey and successfully measured another 77 residences (50 and 27 for urban and rural districts, respectively). The two districts were selected mainly because the local public health officers were quite willing to assist the initial survey and to inform residents of the second survey. Except for meteorological conditions, the two surveys came up with very similar findings regarding residential characteristics and power facilities surrounding the houses. The mean residential MF for the urban residences was .121 and .140 micro-Tesla (microT) (P = .620) for the two surveys. The corresponding figures for the rural residences were .119 and .115 microT (P = .802). Although limited in its scope, this study tends to indicate that measurement studies of residential MF are less likely to suffer from serious selection bias if sampling is confined within a small district where people have similar socioeconomic characteristics.     

Knowledge of rabies among rural community in Chengalpet district,India

The objective of the present study is to assess the knowledge about rabies among the general population of a rural area in Chengalpattu district of Tamilnadu. A cross-sectional study was conducted among 361 participants belonging to Paranur village of Chengalpattu district. A pre-tested questionnaire was utilized to gather information on socio-demographic factors, knowledge about rabies, treatment-seeking behavior, and anti-rabies vaccine use among participants with history of dog bite. Among the 361 participants, only 49.5 % were aware of local wound-management procedures, despite the fact that 68% had sufficient knowledge about rabies. The present study highlights. significant association between knowledge regarding rabies with demographic variables such as gender, age, education and occupation Although more than half of the study population had adequate knowledge on rabies, one-fourth of them had no knowledge on first-aid treatments or vaccines at the time of dog bite. This study highlights the need to promote knowledge regarding wound care and post-exposure prophylaxis at the event of a dog bite.
