The purpose of this prospective cohort study was to assess the performance of tooth-supported, long-span, zirconia fixed dental prostheses (FDPs). Thirty FDPs with span lengths from 36 to 46 mm (mean 40·33 mm), with 4-7 units and with connector dimensions ∼9 mm2 were inserted (19 in the posterior region, 11 including anterior teeth) using glass-ionomer cement. The performance of the FDPs was assessed (aesthetic evaluation, failures, hypersensitivity/tooth vitality, secondary caries, pocket depth, decementation, and chipping) at baseline and after 5 years. Cox regression analysis was performed to identify risk factors. There were 16 failures after 5 years. Framework fracture occurred for two FDPs, four FDPs had to be re-cemented, one abutment tooth had to be treated endodontically, one abutment tooth fractured and cohesive failure of the veneer occurred for eight. Four FDPs had to be replaced, so survival was 82%. The aesthetics were rated as excellent by the patients at baseline and good at the 5-year recall. Cox regression analysis showed that both length [ P = 0·05, exp(B) = 1·22] and location [ P = 0·019, exp(B) = 4·09] of the FDP were risk factors for failure. Compared with the previously published 2-year results, the incidence of complications increased dramatically. Additionally, it was shown that long-span FDPs in the molar region are at greater risk of failure than FDPs in the anterior region. [ABSTRACT FROM AUTHOR]

Background: There is limited information available about the oral and denture hygiene and oral health of nursing-home residents with cognitive and motor impairments., Aims: The purpose of this study was to identify factors influencing the oral and denture hygiene and oral health of nursing-home residents with cognitive and motor impairments., Methods: The study was performed in nine nursing-homes in Germany. Sociodemographic and general data were collected for all participants (n = 150). The Clinical Dementia Rating (CDR) was used to identify the presence of dementia, and the Apraxia Screening Test (AST) was used to identify motor impairment. A comprehensive dental examination was also performed. This included the documentation of dental and denture status and the number of decayed, missing and filled teeth (DMFT). In addition, dental and denture hygiene were assessed using the Plaque Index (PI) and the Denture Hygiene Index (DHI). Univariate and multivariate regression models were used to analyse possible factors affecting the dependent target variables., Results: In multivariate regression analysis, the factors that most strongly influenced greater PI were a lower number of medications taken (p = 0.018), poorer general health (p = 0.013) and the presence of dementia (p < 0.010). A more advanced age (p = 0.036) and longer nursing-home stay (p = 0.048) had a negative effect on the DHI. Furthermore, gender (p = 0.037, in favour of women), poorer general health (p = 0.003), presence of dementia (p = 0.003), and the absence of natural teeth (p = 0.028) influenced poorer oral health. The factors most strongly influenced greater number of missing teeth were a more advanced age (p = 0.021) and longer nursing-home stay (p = 0.015). In terms of fewer filled teeth, a shorter nursing-home stay (p = 0.002) was the factor most strongly influenced this., Conclusions: Poorer general health and the presence of apraxia and cognitive impairment are the main determinants for poorer oral hygiene and oral health among nursing-home residents. A longer nursing-home stay also seems to be relevant for oral health and denture hygiene.

Objective: The aim of this study was to evaluate the effects of dental status and chewing efficiency on the oral-health-related quality of life (OHRQoL) of nursing-home residents., Materials and Methods: The study was conducted in nine nursing homes. All eligible participants were included, and general and medical data, information about nutritional status and their dental and prosthetic status were collected. Chewing efficiency was assessed by means of a two-colour mixing-ability test. The simple count version of the Geriatric Oral Health Assessment Index (SC-GOHAI) was used to evaluate participants' OHRQoL, and the Mini-Mental State Examination to classify the presence of cognitive impairment. Univariate and multivariate regression models were used to analyse data., Results: The mean age of the participants was 82.1 (± 9.8) years and most participants suffered from at least very mild cognitive impairment. OHRQoL for all participants ( n = 143) and denture wearers only ( n = 105) was substantially associated with the type of prosthesis, the presence of natural teeth, the number of functional occluding pairs and dental and denture-related (if applicable) treatment needs. Furthermore, in both model's univariate analysis showed that chewing efficiency also affected OHRQoL. In contrast, multivariate analysis of all participants revealed that only a higher number of functional occluding pairs (C: 0.250; p < 0.001), fewer dental treatment needs (C: -1.733; p = 0.019) and a better nutritional status (C: -1.298; p = 0.048) were relevant for better OHRQoL. For denture wearers, a higher number of functional occluding pairs (C: 0.192; p = 0.011), a better denture condition (C: -2.194; p = 0.003) and a higher body mass index (BMI) (C: 0.145; p = 0.006) were the main variables associated with better OHRQoL among participants., Conclusion: Good oral health and oral function, including chewing efficiency, are associated with a high OHRQoL of nursing-home residents. However, few dental treatment needs, well-fitting dentures without treatment needs and a high number of functional occluding pairs seem to be the principal variables for an acceptable OHRQoL of nursing-home residents., Competing Interests: The authors declare that they have no conflicts of interest., (© 2020 Zenthöfer et al.)

Purpose: To assess the extent of differences between the oral health of people aged 50 and 70 years in a community-based setting., Materials and Methods: This research is part of the Interdisciplinary Study on Adult Development (ILSE). All participants lived in the city of Heidelberg, Germany. For the dental study, 194 participants born 1930-1932 (n = 88) or 1950-1952 (n = 106) underwent a comprehensive dental examination. For each participant the number of teeth present, the number of decayed, missing, and filled tooth surfaces (DMF-S), the Plaque Index (PI), the Gingiva Index (GI) and the Community Index of Periodontal Treatment Needs (CPITN) were determined. Depending on the structure of the data, differences between the birth cohorts were calculated by use of t tests or chi-squared tests. Multivariate analysis was also performed to assess possible effects of gender and birth cohort., Results: Oral health conditions were significantly worse among septuagenarians than among quinquagenarians. Besides poorer oral hygiene, as measured by use of PI and GI (p <0.001), periodontal conditions were worse for septuagenarians (p <0.001), who also had fewer natural teeth (p <0.002); the number of carious lesions was similar in the cohorts (p >0.05). These results were confirmed by multivariate analysis and seem to be mostly gender independent., Conclusions: Oral hygiene and health is poor for quinquagenarians and septuagenarians, with more problems associated with greater age but not with gender. Longitudinal studies are necessary to evaluate the intraindividual development of changes of oral health during ageing.

Purpose: The purpose of this study was to identify how changes to general health might affect the oral health of nursing-home residents over a six-month period., Materials and Methods: The study was conducted in nine nursing homes in Germany. Sociodemographic and general data were collected at baseline and after six months. Complete baseline and follow-up data were available for 114 participants. The Clinical Dementia Rating (CDR) and the Global Deterioration Scale (GDS) were used to identify the presence and, if applicable, severity of dementia among participants. The Apraxia Screen of TULIA (AST) was used to identify motor impairment. A comprehensive dental examination of each participant was also performed. The examination included the documentation of dental and denture status and the number of decayed, missing and filled teeth (DMF-T). In addition, dental and denture hygiene were quantitatively assessed using the Plaque Index (PI) and the Denture Hygiene Index (DHI), respectively. Global dental treatment needs were evaluated by use of the Oral Health Assessment Tool (OHAT). Univariate and multivariate linear regression models were compiled to analyse possible factors affecting the dependent target variables., Results: During the study period, denture hygiene among the study population worsened by an average of 15%. The regression models detected that a more advanced age (in years) was associated with a less pronounced deterioration of denture hygiene as measured by use of the DHI (-0.806 per additional year of age; p = 0.030). Furthermore, an increase in the level of care needed (coefficient (C): -1.948; p = 0.002) and a more poorly graded assessment of general health compared with the value at baseline (C: 1.054; p = 0.026) were both associated with a deterioration of oral health as evaluated by use of the OHAT. In addition to these results, an increase in care needs was also associated with a deterioration of dental health as evaluated by use of the DMF-T (C: 0.966; p = 0.013)., Conclusion: In the short term, a deterioration of general health, including an increase in care needs, seems to be the predominant factor associated with a more pronounced deterioration of oral health among nursing-home residents., Competing Interests: The authors report no conflicts of interest regarding this manuscript., (© 2020 Klotz et al.)

Objective: The objective of this study was to evaluate possible longitudinal associations between oral health-related quality of life (OHRQoL) and subjective well-being among quinquagenarians and septuagenarians over up to 10 years of clinical observation., Methods: This research is part of the "Interdisciplinary Study on Adult Development and Aging (ILSE)." All participants lived in an urban region of southwest Germany. One hundred and fifty-two participants born in 1930-1932 (older cohort, OC; n = 54) and 1950-1952 (younger cohort, YC; n = 98) underwent comprehensive psychological, medical and dental examinations at baseline and up to 10 years thereafter. The Geriatric Oral Health Assessment Index (GOHAI) was used to assess OHRQoL. The Philadelphia Geriatric Center Morale Scale (PGCMS), general life satisfaction (GLS) and individuals' general satisfaction with their health (SWH) were used to evaluate subjective well-being. Regression models and structural equation modelling (SEM) were used to analyse the longitudinal associations between OHRQoL and subjective well-being., Results: A cross-lagged prediction model revealed a positive association between baseline OHRQoL and subjective well-being across 10 years for both birth cohorts, OC [0.49 (0.21; 0.69)] and YC [0.36 (0.24; 0.52)]. However, higher subjective well-being at baseline was not a predictor of better OHRQoL 10 years later for either cohort., Conclusions: OHRQoL seems to be a substantial predictor of subjective well-being in quinquagenarians and septuagenarians across the rather long observational period. Further studies with larger sample sizes are required to confirm this finding., (© 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: The purpose of this work was to investigate the long-term effectiveness of oral health education of caregivers in nursing homes with care-dependent and cognitively impaired residents., Methods: Fourteen nursing homes with a total of 269 residents were allocated to a control group, with continued normal care, or to an intervention group. Allocation was performed at nursing home level. In the intervention group, caregivers were given oral health education, and ultrasonic cleaning devices were provided to clean removable prostheses. Oral health was assessed at baseline and after 6 and 12 months by use of the Plaque Control Record (PCR), Gingival Bleeding Index (GBI), Community Periodontal Index of Treatment Needs (CPITN) and Denture Hygiene Index (DHI). Mixed models for repeated measures were performed for each target variable, with possible confounding factors (intervention/control group, age, sex, residence location and care-dependence)., Results: In the control group, no changes of target variables were observed between baseline and the 6- and 12-month follow-ups. After 6 and 12 months, PCR and DHI were significantly improved in the intervention group. For PCR, the intergroup difference of improvements was -14.4 (95% CI: -21.8; -6.9) after 6 months. After 12 months, the difference was -16.2 (95% CI: -27.7; -4.7). For DHI, the intergroup difference compared to baseline was -15 (95% CI: -23.6; -6.5) after 6 months and -13.3 (95% CI: -24.9; -1.8) after 12 months. There was neither a statistically significant effect on GBI nor on CPITN. Care-dependency showed a substantial trend to smaller improvements in PCR (P = .074), while an inverse effect was apparent for DHI (P < .001)., Conclusions: Education of caregivers improves and maintains the oral health of care-dependent nursing home residents over longer periods. Use of ultrasonic devices is a promising means of improving denture hygiene among the severely care-dependent. Such interventions can be easily and cheaply implemented in routine daily care., (© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Diminished oral health of the institutionalized elderly has frequently been reported. This is not only of significance with regard to nutrition and general health, but it can also affect oral health-related quality of life. This paper evaluates the effects of oral and general conditions on oral health-related quality of life for the institutionalized elderly, as measured by the Geriatric Oral Health Assessment Index (GOHAI)., Materials and Methods: Ninety-four residents of four long-term care homes in southern Germany agreed to participate in this study, and interviews were conducted using the GOHAI questionnaire. The Revised Oral Health Assessment Guide was applied to allocate participants into two groups: satisfactory oral health and poor oral health. To evaluate the effects of age, gender, number of chronic diseases, frequently taken drugs, care level, Mini-Mental State Examination score, periodontitis (for participants with their own teeth), pressures caused by prostheses, and type of denture worn, a linear regression model with the total GOHAI score was calculated with these determinants., Results: The mean ± SD GOHAI score was 53.3 ± 6.2 in the satisfactory oral health group and 48.7 ± 7.3 in the poor oral health group. Statistical analysis showed that the GOHAI scores were significantly different in satisfactory oral health and poor oral health groups (P = 0.030) and were affected by care level (P = 0.008) and type of dentures worn (P = 0.006)., Conclusions: Within the limitations of this study, it can be concluded that oral health-related quality of life of the institutionalized elderly is low and is positively associated with better oral health., (© 2014 The Authors.

Unlabelled: Older people with dementia are very dependent on nursing, and caregivers are frequently confronted with oral-care-resistant behaviour which may lead to shortcomings in oral health., Objective: To compare oral hygiene and health status of institutionalised older people suffering, or not, from dementia., Basic Research Design: Prospective cohort study (single-blind)., Clinical Setting: Institutionalised older population in south-west Germany., Participants: Ninety-three, allocated to two groups: dementia (n = 57) and non-dementia (n = 36) based on a mini mental state examination., Main Outcome Measures: Target variables were plaque control record (PCR), gingival bleeding index (GBI), community periodontal index of treatment needs (CPITN), and denture hygiene index (DHI). Differences between the dementia and non-dementia groups were evaluated by univariate testing of all target variables., Results: Univariate analysis revealed the amount of plaque in the dementia group was significantly higher than in the non-dementia group (p = 0.004). Mean CPITN of participants in the dementia group was significantly worse than those of participants in the non-dementia group (p < 0.001). All participants in the dementia group had periodontitis in at least one of the sextants, compared with 74% in the non-dementia group (p < 0.001). For DHI (p = 0.198) and GBI (p = 0.275) no differences were found between the groups., Conclusions: Some aspects of oral hygiene and health seem to be worse for the institutionalised older people with dementia. Permanent specially adapted intervention for residents suffering from dementia in long-term care homes, and training for caregivers, is desirable to maintain life-long oral hygiene and health.

Aims: To evaluate the additional operating expenses caused by shade matching by dental technicians in the dental practice and by color changes of fixed partial dentures., Methods: A questionnaire was handed out to visitors of the 2010 ADT dental technician congress in Germany. Thirty-one completed questionnaires were evaluated., Results: Mean costs caused by shade matching and shade correction per month were 1269$ (SD = 1278$; n = 25) and per unit of FPD 9.32$ (SD = 8.89$)., Conclusions: An improvement of shade matching, shade communication and reproduction should be made in order to minimize the considerable economic damage for dental laboratories.

Objective: To obtain information about the subjective oral health status of non-clinical elderly populations of urban regions of Germany, one in the East and one in the West, by using OHIP-14 and, for first time, the GOHAI, and, furthermore, to compare the results obtained by use of both instruments., Basic Research Design: Cross-sectional., Clinical Setting: Randomly chosen, non-clinical elderly population in urban regions of Germany., Participants: 197 participants (51% male) born in the years 1930-1932., Main Outcome Measures: GOHAI, OHIP-14., Results: Median GOHAI score was 54; median OHIP-14 score was 2. Scores indicative of severely impaired oral health were rare. The effect of living in eastern or western Germany was of minor significance. Although the internal consistency of both measures was comparable and the same positive association with psychological wellbeing, absence of dry mouth, burning mouth, and removable dentures (p < 0.05) was observed, differences occurred. In simultaneous analysis of all items, factor analysis revealed only partial overlap of the items in extracted factors. Furthermore, the extreme score indicating no impairment was five times more frequent for OHIP-14. Of those who scored zero in OHIP-14, only 20% had the GOHAI equivalent score of 60, and for some GOHAI items the answer category for highest impairment was obtained., Conclusions: GOHAI scores for this randomly chosen non-clinical group enable comparison with scores for Germany measured in the future. The differences between GOHAI and OHIP-14 make it necessary to select the most appropriate instrument for a planned purpose and study population.

Objective: Very little is known about the ability of physicians to assess oral health of geriatric patients. The aim of this pilot study was to assess the in ter-examiner reliability in assessment of oral health for a dentist and a physician, and to evaluate the influence of training in dental findings for the physician on inter- examiner reliability., Methods: Inter-examiner reliability between a physician and a dentist was tested in a primary geriatric hospital with 126 participants 60 years old or more (mean 77 years; 32% men) using the Revised Oral Assessment Guide (ROAG) and additional items relating to caries and dentures (14 items). Calculated were kappa-coefficients, and percentage agreement between the examiners before (n = 50) and after (n = 51) training for the physician in dentistry (n = 25 for the common training session)., Results: Before the training both kappa-values and percentage agreement were not acceptable in the different categories. After the training, with the exception of the categories swallow and tongue, the reliability of all items was moderate or good. The number of occasions on which the physician underestimated the clinical finding compared to the dentist - indicating a clinical finding was overlooked - decreased for every item; for retention of denture and decayed teeth this decrease was significant., Conclusion: Screening for oral health performed by a physician was insufficient regarding the different clinical aspects. Training in the use of an oral health assessment tool improved the reliability of the screening. Because of the low number of examiners the results should be interpreted as a pilot investigation on this new topic.

Objective: The purpose of this study was to identify which categories of chronic stress increase during medical and dental education., Methods: 96 dental and 140 medical students were included. Chronic stress was assessed before the beginning of an undergraduate course and after the end of the same course. The Wilcoxon signed-rank test for matched pairs was used to find differences between the pre-course and post-course situation. Differences between dental and medical students were assessed using non-parametric tests., Results: For both medical and dental students stress value of the variables 'work overload' and 'overextended at work' increased significantly after the course. For dental students the variables 'social overload', 'performance pressure at work', 'lack of social recognition' and 'worry propensity' increased, too. For medical students the variable 'social isolation' increased, additionally., Conclusions: In both medical and dental educational courses some subcategories of chronic stress increased. However, this increase is more pronounced in dental education.

Objectives: Translation, reliability analysis and validation of a German version of the Geriatric/General Oral Health Assessment Index (GOHAI) was the aim of this study., Methods: Translation was performed by a forward-backward process. Validity was assessed as convergent validity in comparison with another self-perceived assessment of oral health (OHIP-14) and as group validity (n = 218; mean age 73 years). Reliability was proved in terms of internal consistency, inter-item and item-scale correlations, and stability (test-retest procedure; n = 36; mean age 77 years). The responsiveness to change in oral health status was assessed by pre- and post-treatment comparison (n = 21; mean age 63 years)., Results: A German version of the GOHAI is presented. Convergent validity was sufficient (r = -0.76 compared with OHIP-14); group validity could be demonstrated for self-perceived need for treatment, chewing problems, number of own teeth, caries lesions present and dental status. The internal consistency was high (Cronbach's alpha = 0.92) as were inter-item and item-scale correlations, for which good homogeneity of the index was apparent. The test-retest correlation for the summary score was r = 0.84, single item correlations ranged from r = 0.36 to r = 0.89. The GOHAI sum score increased significantly after patients received new dentures, indicating responsiveness of the GOHAI to clinical change in the expected direction., Conclusions: The German version of the GOHAI had sufficient reliability, validity and responsiveness to be used as measure of oral health-related quality of life in cross-sectional and longitudinal studies of the elderly.

Objective: The aim of this study was to investigate factors associated with the oral health-related quality of life (OHRQoL) of institutionalized elderly in Germany., Material and Methods: One-hundred-and-fifty-eight subjects from old people's homes were selected (mean 82.8 years). OHRQoL was measured using the Oral Health Impact Profile (OHIP). Denture characteristics (kind and age of denture, retention of removable denture, number of teeth in static occlusion) and general issues (age, gender, education level, and general pain status) were assessed. All factors were subjected to bivariate testing for their effects on the OHIP summary score (OHIP-SC) and to multivariate testing in subjects with removable dentures (n = 128); a linear regression model with backward elimination was used, with OHIP-SC as the dependent variable., Results: In the context of other studies, a median OHIP-SC of 29 indicated highly impaired OHRQoL. According to the bivariate analysis, retention, age of denture, number of teeth in static occlusion, general pain status, and education all exhibited significant influence on OHIP-SC. In the final linear regression model, general pain status, education level, and retention of denture remained at a statistically significant level. The model explained 34% (R2 = 0.34) of the variance of the OHIP-SC. The kind of denture had no significant impact on OHIP-SC., Conclusions: In contrast to other groups, the kind of denture exhibited little impact on OHIP-SC for this highly specific collective. However, there were functional aspects of dentures which seemed to be important. Non-dental factors had a striking effect on OHRQoL.

Purpose: The aim of this study was to describe the oral health related quality of life (OHRQoL) of institutionalized elderly., Material: 159 elderly were randomly selected for this, study ranging in age from 61 to 98 (mean age 82.8; 19.1% male, 80.9% female). For measuring the OHRQoL the Oral Health Impact Profile (OHIP) was used. Additionally, a dental status was evaluated., Results: 15% of the subjects had only natural teeth or fixed dentures, 80% removable dentures and 15% no dentures at all. OHIP-mean reached 33+/-25 points, between 0 and 112. The subcategory "functional limitation" showed the highest impairment (6.3%). The items with the highest impairment on OHRQoL in the different subcategories were: dentures not fitting properly, uncomfortable dentures, self-conscious due to teeth, avoid eating some foods, felt depressed, avoid going out and general health worsened., Conclusions: The OHIP summary score represents an overview of OHRQoL and answers detailed questions with the help of the single items. In institutionalized elderly many items showed impairment, especially in items concerning the prosthetic restorations. This demonstrates the need for dental aftercare and not only dental interventions for acute pain. Establishing aftercare and prophylaxis could increase the OHRQoL and subsequently the overall well-being.
