Denture base materials: An in vitro evaluation of the mechanical and color properties. J Dent 2024; 145:104993. [PMID: 38657724 DOI: 10.1016/j.jdent.2024.104993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 03/26/2024] [Accepted: 04/10/2024] [Indexed: 04/26/2024] Open
Abstract
OBJECTIVES This study aimed to compare the physical and mechanical properties of four denture base materials: Polyan IC (PA), milled polymethylmethacrylate (PMMA), three-dimensional (3D)-printed resin (3DP), and SR Ivocap (SR). METHODS Ninety-six samples were prepared and divided into four groups as follows. Group A consisted of 3DP (Asiga DentaBASE, Asiga) fabricated using a manufacturer-recommended 3D printer (Asiga Pro 4k, Asiga). Group B comprised milled PMMA (MP) (Ivotion Base, Ivoclar Vivadent). Group C included PA (BredentSenden), meanwhile, group D involved SR (Ivoclar VivadentSchaan). Cuboid samples (65 mm x 10 mm x 2.5 mm) were used for biaxial flexure strength testing in a universal testing machine (UTM). Cylindrical samples of 20 mm x 40 mm were used for compressive strength testing in a UTM. Additionally, cuboid samples (65 mm x 10 mm x 2.5 mm) were used for Vickers surface hardness testing in a microhardness tester. disk samples (10 mm x 2.5 mm) were employed for color stability testing both in a coffee solution and Coca-Cola, using a digital spectrophotometer. Statistical analyses were performed using one-way analysis of variance and Tukey's post hoc analysis (α=0.05). RESULTS MP demonstrated superior compressive strength (p = 0.002) and color stability compared to that exhibited by 3DP (p < 0.001) while displaying similar flexure strength (p = 0.336) and hardness (p = 0.708). MP and PA displayed similar compressive strength (p = 0.081), flexure strength (p = 0.159), and color stability in coke (p = 0.071). However, MP had reduced hardness (p < 0.001) and color stability in coffee (p < 0.001). Moreover, MP demonstrated a higher compressive strength (p < 0.001) than that displayed by SR. However, the flexure strength, hardness, and color stability were similar (p > 0.05). Furthermore, 3DP exhibited comparable compressive strength (p = 0.334) to that of PA but demonstrated significantly lower flexure strength (p = 0.005), hardness (p < 0.001), and color stability (p < 0.001) compared to PA. In comparison to SR, PA had a higher compressive strength (p < 0.001), hardness (p = 0.001), and color stability in coffee (p < 0.001), although they demonstrated similar (p > 0.05) flexure strength and color stability in coke. CONCLUSIONS The MP and PA demonstrated superior compressive strength than that exhibited by the other materials tested. The tested materials had similar flexure strengths, except for PA which demonstrated superiority over the 3DP. Among all tested materials, PA exhibited the highest hardness, while the 3DP was the least color-stable. CLINICAL SIGNIFICANCE Considering the mechanical properties and color stability, Polyan and milled polymethylmethacrylate are preferred for complete denture fabrication. However, the limited repairability and complex handling of Polyan should be considered.

Oral health and nutritional status in care-dependent, community-dwelling older adults in Zurich, Switzerland. SWISS DENTAL JOURNAL 2024; 134:122-144. [PMID: 38739774 DOI: 10.61872/sdj-2024-02-09] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Indexed: 05/16/2024]
Abstract
The aim of this study was to assess the oral health status (OHS), Oral health impact profile (OHIP-G-14), and the nutritional status (NS) in community-dwelling, dependent older adults. Information on OHS including DMF(T), plaque (PI) and gingival (GI) indices, community-periodontal-index-for-treatment-needs (CPITN), OHIP-G-14, maximum bite force (MBF), chewing efficiency [subjective (SA) and quantitative (VoH) assessments] were collected. NS was obtained by Mini-nutritional assessment (MNA) and body mass index (BMI). Cognitive status was evaluated by the mini-mental state examination (MMSE). 240 elders (mean-age = 81.5 ± 8.9y; men =85, women =155) were recruited. Average number of teeth, functional occlusal units and DMF(T), were 18.8 ± 8.9, 7.7 ± 3.5, and 22.3 ± 5.3 respectively. Mean PI, GI, CPITN and OHIP-G-14 were 1.8 ± 0.8, 1.2 ± 0.8, 1.9 ± 1.1, and 8.0 ± 12.0, respectively. MBF, VoH, SA were 219.6 ± 193.6, 0.3 ± 0.2, and 3.3 ± 1.4, respectively. MNA and BMI were 22.9 ± 4.7 and 25.5 ± 5.3, respectively. Number of teeth reduced significantly with age (P < 0.001), cognitive decline (P < 0.001). Oral hygiene significantly deteriorated with cognitive decline (P < 0.001). OHIP scores were negatively affected by increasing cognitive decline (P < 0.001). MNA deteriorated in women (P = 0.026), with increasing age (P = 0.015), and advancing cognitive decline (P < 0.001). BMI reduced with advancing age (P = 0.003) and in women (P = 0.016). Based on the findings of this study, it may be concluded that advancing age and cognitive decline, negatively impacted the oral health, oral function, oral health-related quality of life, and the nutritional state of care-dependent community-dwelling older adults.

Reliability of a face scanner in measuring the vertical dimension of occlusion. J Dent 2024; 146:105016. [PMID: 38679136 DOI: 10.1016/j.jdent.2024.105016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 04/18/2024] [Accepted: 04/21/2024] [Indexed: 05/14/2024] Open
Abstract
OBJECTIVE This study evaluated the reliability of a face scanner in measuring the vertical dimension of occlusion (VDO). METHODS Fully dentate volunteers (n = 20; mean-age = 30.0 ± 10.7 years) were recruited. Clinical facial measurements were obtained using a digital caliper and a face scanner (Obiscanner, Fifthingenium, Italy). The scans were imported into a mesh-processing software, and the distances were measured digitally. Measurements were obtained for each participant with the jaws positioned in maximal intercuspation (MI) and with increased vertical distances of 2, 4, and 6 mm. Vertical and horizontal measures were obtained using facial anatomical landmarks: Glabella (GL), Pronasale (PrN), Subnasale (SbN), inferior border of the right and left Alare, Labiale superius (Ls), right and left Cheilion (Ch), Soft Pogonion (SPg), right and left Tragus of the ear (Tr), for all selected vertical positions. Data analysis included intra-class correlation coefficient (ICC), pairwise comparison tests, Bland-Altman plots, and Passing-Bablok regression. RESULTS 120 VDO measurements (clinical=60, digital=60) were recorded by two independent evaluators. Mean differences between digital and clinical measurements ranged from 0.054 ± 0.14 mm to 0.203 ± 0.13 mm. All parameters were strongly correlated (r > 0.93; p < 0.001). ICC estimates revealed excellent reliability, and the measuring procedure yielded the same results on repeated trials irrespective of the raters and measurement methods. Bland-Altman plots revealed a difference, between digital and clinical measurements, of 1.7 % for the vertical measurements. Regression analysis revealed no significant proportional difference between the two methods, so both can be used interchangeably. CONCLUSIONS The findings of this study demonstrate that VDO can be measured accurately from face scans using 3D mesh-processing software and that even small changes in the VDO could be detected using the digital methods. CLINICAL SIGNIFICANCE Findings provide evidence about the reliability of a digital method for jaw relation registrations and may be applied towards incorporating this method into clinical workflows for computer-aided-design/ computer-assisted-manufacturing (CAD-CAM) dentures.

Edentulism and Individual Factors of Active Aging Framework in Colombia. Ann Geriatr Med Res 2024; 28:46-56. [PMID: 38105010 PMCID: PMC10982444 DOI: 10.4235/agmr.23.0158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 11/28/2023] [Accepted: 12/08/2023] [Indexed: 12/19/2023] Open
Abstract
BACKGROUND While edentulism remains a serious public health problem for older adults in Colombia, few analyses have been conducted from the framework of active aging as a part of the positive discourse of aging. This study analyzed complete edentulism and its relationship with determinants including personal, behavioral, and health systems and social services. METHODS This study included a total of 19,004 older adults. We used univariate, bivariate, and multivariate logistic regression type scores to investigate the relationships between the variables. The personal determinants included basic (Barthel scale) and instrumental activities of daily living (Lawton scale), public transportation, functional limitations, self-perceived health, and health problems. The behavioral factors included alcohol and tobacco use, mini nutritional tests, and physical activity. The last determinant was the healthcare system, while social services access included dental services. The analysis also included sociodemographic variables. RESULTS The results revealed significant associations for the variables of the three determinants, including the risk of malnutrition (odds ratio [OR]=1.15), functional limitation (OR=1.15), moderate physical activity (OR=1.08), and access to dental services (OR=2.31). Sex, years of education, and race were also risk factors, among other variables. Personal determinants, behavior, and use and access to health services were related to edentulism in older adults. CONCLUSION These findings support the need to include different analyses of edentulism from multicausality and to understand the oral cavity and the living conditions of aging adults.

Acceptance of silver diamine fluoride use in community dwelling older adults, nursing home residents, and caregivers. J Dent 2024; 141:104819. [PMID: 38128821 DOI: 10.1016/j.jdent.2023.104819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 12/14/2023] [Accepted: 12/18/2023] [Indexed: 12/23/2023] Open
Abstract
OBJECTIVES To compare the level of acceptance of silver diamine fluoride (SDF) treatment between different functional groups of older adults aged 65-years-old and above. METHODS Three groups were recruited representing functionally-independent ("Community dwelling"), frail ("Nursing home"), and functionally-dependent older adults ("Caregiver": proxy respondent involved in caring for an older adult of all functional levels). Participants viewed a video on SDF and an interviewer-led questionnaire collected demographics, dental experience and perception on SDF use. RESULTS The study recruited 201 participants (100 "Community dwelling", 51 "Nursing home", 50 "Caregiver"). Overall, 73 % of participants were accepting of SDF treatment. Those in the "Community dwelling" group were most accepting (85 %), followed by the "Nursing home" group (61 %) and "Caregiver" group (60 %) (p<0.001). Participants were more accepting of SDF use on posterior (73 %) compared to anterior teeth (46 %). They were more accepting when SDF was presented as a treatment to avoid infection and pain (87 %), and general anesthesia (78 %). In a regression analysis, "Nursing home" and "Caregiver" participants were three times less likely to accept SDF (OR 0.27 [95 % CI: 0.13 to 0.60], and OR 0.27 [95 % CI: 0.12 to 0.58] respectively) compared to "Community dwelling" participants. After adjusting for other factors, only the "Caregiver" group remained significant (Adjusted OR 0.32 [95 % CI: 0.13 to 0.78]). CONCLUSIONS Older adults were accepting of SDF and this treatment modality has the potential to be a routine treatment option in dental caries management in this population. However, this was less certain among frail and functionally dependent older adults. CLINICAL SIGNIFICANCE An SDF program to manage caries is likely to be well-received by functionally-independent older adults. However, the acceptance among frail and functionally-dependent older adults were lower even though SDF is mostly likely to benefit these populations. There is a need to investigate this relatively lower levels of acceptance.

Exploring the knowledge, attitudes, and performance of dentists in providing care to elderly patients. BMC Oral Health 2024; 24:62. [PMID: 38195514 PMCID: PMC10777511 DOI: 10.1186/s12903-023-03832-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Accepted: 12/26/2023] [Indexed: 01/11/2024] Open
Abstract
BACKGROUND Supportive care and dental treatment for older adults are crucial in addressing the global emergency of population aging, requiring specialized healthcare services and knowledge-based practices. METHODS This cross-sectional content analysis study was conducted on 150 general dentists in Kerman in 2021. The participants were selected using cluster sampling. The data were collected using a questionnaire with four sections assessing the participants' demographic characteristics, knowledge, attitudes, and performance. The data were analyzed with SPSS-26 software using the t-test, ANOVA, and linear regression analysis. RESULTS The dentists' mean age was 36.10 ± 7.60 years. The mean knowledge score of the participants was 5.29 ± 1.49 (out of 9). The mean attitude score was 59.42 ± 11.6 (out of 85), and the mean performance score was 24.13 ± 4.96 (out of a maximum of 35). The data showed a positive relationship between the dentists' knowledge, attitudes, and performance. However, the participants' gender had no significant correlation with their knowledge, attitudes, or performance. It was also shown that 50% of dentists had adequate experience treating elderly patients with complex medical problems. CONCLUSIONS The participants had an adequate level of knowledge and performance and a positive attitude toward dental care for older adults. Health officials and administrators need to organize and hold effective training and refresher courses on geriatric dentistry to promote dentists' knowledge and performance.

DENTAL PATIENT-REPORTED OUTCOMES IN GERIATRIC DENTISTRY : A call for clinical translation. J Evid Based Dent Pract 2024; 24:101958. [PMID: 38401948 DOI: 10.1016/j.jebdp.2023.101958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 02/26/2024]
Abstract
As the proportion of older adults in the world population increases, there is an increasing need to provide adequate dental care for this very heterogeneous group of individuals. The relationship between oral and systemic health, the impact of medication on oral health, and the influence of accessibility to dental care and other social and environmental factors shape the provision of dental care for older adults more than in children, younger, and middle-aged adults. However, while dental care for older adults is shaped by these factors and is often different from the care for other adults, what matters to older dental patients does not differ from what matters to dental patients in general. The four dimensions of oral health-related quality of life (OHRQoL)-Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact-capture dental patients' suffering from oral disorders. OHRQoL questionnaires can be used to assess this impact and to achieve results that are compatible with adults in general. More than in other age groups, cognitive impairments or dementia limit the usefulness of questionnaires or interviews for oral health impact assessment. In these situations, family members or caregivers can assess the patient's oral health impact, and oral health care providers need to rely more on physical oral health characteristics for clinical decision-making than in other dental patients. While the tools to measure oral health impact change, the targets for dental care stay the same. Prevention and reduction of functional, painful, aesthetical, and broader psychosocial impact related to oral disorders are the central tasks for geriatric dentistry as they are for dentistry in general. The aim of the manuscript is to highlight the importance of patient-reported outcome measures in geriatric dentistry, addressing challenges and opportunities for their application.

New measure of functional tooth loss for successful Oral ageing: a cross-sectional study. BMC Geriatr 2023; 23:859. [PMID: 38102557 PMCID: PMC10722707 DOI: 10.1186/s12877-023-04570-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Accepted: 12/05/2023] [Indexed: 12/17/2023] Open
Abstract
BACKGROUND This cross-sectional study evaluated the impacts of functional tooth loss on oral health-related quality of life (OHRQoL) among elderly people compared with the impacts of several common indicators of oral health. Additionally, the cut-off of functional tooth loss needed for a better OHRQoL was investigated to establish a new measure for successful oral ageing. METHODS Data from people aged 65-74 were extracted from the Fourth National Oral Health Survey in Sichuan, China. Functional tooth loss was defined as both natural tooth loss and nonfunctional teeth, such as third molars, residual roots, and removable dentures. The cut-offs of tooth loss were first identified as 12, based on the previous definition of functional dentition (≥20 natural teeth except the third molars), and 14, 16, or 18 for further investigation. OHRQoL was evaluated by the standardized Geriatric Oral Health Assessment Index (sGOHAI) score. Logistic regression was performed to estimate the impacts on OHRQoL. Additionally, subgroup analyses were conducted using the stratified chi-square test to explore the effect of functional tooth loss at each position. RESULTS The mean GOHAI score of the 744 participants was 48.25 ± 7.62. Elderly people who had lost ≤12 functional teeth had greater odds of reporting a higher sGOHAI score than those who had lost more functional teeth (odds ratio (OR) 1.49, 95% confidence interval (CI) 1.05-2.11). No significant difference in the sGOHAI score was detected between people who had lost 13-16 functional teeth and those who had lost ≤12 functional teeth (0.61, 0.35-1.07). The loss of second premolars and first and second molars had great impacts on the sGOHAI score when ≤12 or ≤ 16 functional teeth had been lost. CONCLUSIONS Compared with natural tooth loss, functional dentition and occluding pairs, functional tooth loss can be a better indicator of OHRQoL in the elderly population. Sixteen remaining functional teeth seem to be sufficient to maintain good OHRQoL and successful oral ageing despite that number being previously acknowledged as ≥20 teeth.

How dentists in Egypt perceive their knowledge, attitudes, and barriers they face in providing oral healthcare to geriatric patients: a cross-sectional study. BMC Oral Health 2023; 23:947. [PMID: 38031034 PMCID: PMC10687915 DOI: 10.1186/s12903-023-03690-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Accepted: 11/21/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND Geriatric dentistry is an understudied area in dental schools in Egypt. Our study aimed to assess the knowledge and attitudes of Egyptian dentists regarding geriatric oral health and identify barriers to delivering dental care to geriatric patients. METHODS We conducted an anonymous online cross-sectional study in November and December 2022, targeting dentists with varying levels of experience working in different Egyptian institutions. A 30-item questionnaire assessed the respondent's views on geriatric oral health, perceived knowledge, attitudes, and barriers. The Google form was distributed through emails and commonly used social media platforms. RESULTS A total of 421 dentists responded to this online questionnaire. Of the respondents, 44.9% were male, 45.0% were between 20 and 29 years old, and 31.5% worked in more than one dental setting. Multivariate analysis revealed that female sex negatively affected attitude β = -1.72 [95%CI,-2.43 - -1.11]. The proportion of older patients who visited the respondents' clinics per day (11-30%) and more than 30% increased perceived knowledge [β = 1.01 (95%CI, 0.41 -1.62), β = 1.50 (95%CI, 0.71-2.22)] and attitude [β = 0.70 (95%CI, 0.06-1.40), β = 0.73 (95%, 0.13-1.61)] while decreased the perceived barriers [β = -1.10 (95%CI, -1.91 - -0.32)] respectively. On the other hand, years of experience increased perceived knowledge only after 5-10 years [β = 1.02 (95%CI, 0.04-2.10)] and after more than 10 years [β = 1.30 (95%CI, 0.21-2.70)]. Governmental work only increased perceived barriers [β = 1.33 (95%CI, 0.10-2.54)], while living in the middle and west delta decreased perceived barriers [β = -0.91 (95%CI, -2.12 - -0.01 and β = -1.33, (95%CI, -2.22 - -0.40) respectively]. CONCLUSIONS Our study highlights the need to improve the knowledge and attitudes of young dentists towards geriatric dentistry. Furthermore, working conditions in dental facilities, particularly in the government sector and Upper Egypt, need to be improved to reduce barriers to delivering dental care to geriatric patients.

Dental care utilization among home care recipients, nursing home residents, and older adults not in need of long-term care: An observational study based on German insurance claims data. J Dent 2023; 136:104627. [PMID: 37473830 DOI: 10.1016/j.jdent.2023.104627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 07/10/2023] [Accepted: 07/17/2023] [Indexed: 07/22/2023] Open
Abstract
OBJECTIVES To describe and compare dental care utilization (DCU) among home care recipients, nursing home residents, and older adults not in need of long-term care (LTC). METHODS Using nationwide claims data of 8 German statutory health and LTC insurance funds, proportions of home care recipients (n = 68,137), nursing home residents (n = 21,167), and non-LTC dependents (n = 632,205) aged 65+ years with DCU in 2017 were determined and compared. Associations between DCU and individual characteristics and setting were investigated via multivariable logistic regression. The proportions of individuals with DCU one year before and after transition to (a) home care (n = 23,590) and (b) nursing home care (n = 6,583) were compared. RESULTS Proportions of home care recipients and nursing home residents with DCU were lower compared to non-LTC dependents (51.9, 53.1, and 73.2%, respectively). Adjusted odds ratios for DCU for home care recipients vs. non-LTC dependents ranged from 0.55 (LTC grades 1/2; 95% confidence interval 0.54-0.56) to 0.38 (LTC grades 4/5; 0.36-0.40). For nursing home residents vs. non-LTC dependents they ranged from 0.69 (3; 0.65-0.72) to 0.67 (4/5; 0.63-0.71). Women, older individuals, those with 0-1 diseases of the Elixhauser comorbidity index, dementia, and those from West Germany were also less likely to utilize dental care than their counterparts. Utilization decreased after transition to home care (60.0 vs. 55.6%) and increased after transition to nursing homes (46.1 vs. 53.5%). CONCLUSIONS Nursing home residents and especially home care recipients utilized dental care less frequently than older non-LTC dependents. Organizational barriers for dental care utilization and ways to remove them should be investigated. CLINICAL SIGNIFICANCE Dental care utilization among LTC dependents is low and should be improved in both the home care and nursing home setting.

Abstract
Due to increasing life expectancy and the associated demographic changes, more and more people are dependent on care. To identify a possible need for dental treatment, chewing function tests as assessment instruments have proven their effectiveness. In this article, the reader is given an overview of existing chewing function tests and their implementation. It is important that a patient with pain should be presented to a dentist immediately, regardless of whether a chewing function test is performed. Furthermore, chewing function tests are not a substitute for routine dental examinations, but they could provide information to (dental) laypersons as to whether an appointment should be arranged in a dental practice or whether a dental consultation is necessary.

CAD-CAM complete denture resins: Effect of relining on the shear bond strength. J Dent 2023; 131:104438. [PMID: 36717051 DOI: 10.1016/j.jdent.2023.104438] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 12/20/2022] [Accepted: 01/26/2023] [Indexed: 01/30/2023] Open
Abstract
OBJECTIVES The aim of this study was to compare the shear bond strength of relined CAD-CAM complete removable dental prosthesis (CRDP) resins with conventional heat-polymerized polymethylmethacrylate (PMMA) resin. METHODS A total of 96 resin specimens in identical dimensions of 10 mm × 10 mm × 11 mm were fabricated for four study groups [#1- Conventional heat-polymerized group: n=24 (ProBase); #2- Milled#1: n=24 (Ivobase); #3- Milled#2: n=24 (Ivotion); #4- 3D-printed: n=24, (NextDent Denture 3D+)]. Twelve specimens in each group were sectioned in the middle to produce a 3 mm defect and then were relined using a conventional denture relining material. All specimens underwent thermocycling (5-55°C) for 10,000 cycles. The shear bond tests were carried out in a universal testing machine. One-way ANOVA and Tukey's test were used for statistical analysis (p<0.05). The two-parameter Weibull distribution values were calculated. RESULTS Relined 3D-printed specimens had a significantly lower shear bond strength when compared with conventional (p=0.0003) and milled groups (Milled#1: p=0.0004; Milled#2: p<0.0001). There were no differences in the shear bond strengths between the milled and conventional groups. Weibull distribution presented the highest shape value for the non-relined Milled#1 (22.83) group and the lowest values for the 3D-printed relined group (4.001). CONCLUSION The findings of this study conclude that the shear bond strength of the conventionally-relined 3D-printed resins used for fabricating CRDPs was inferior to the shear bond strength of conventionally-relined resins employed for manufacturing CRDPs using CAD-CAM milling and conventional heat-polymerization techniques. CLINICAL SIGNIFICANCE When considering 3D-printing for the fabrication of CRDPs, it is recommended to employ it in clinical situations where a frequent need for denture relining is not expected.

Dental care for people living with dementia: current challenges and planning for the future. The UK perspective. COMMUNITY DENTAL HEALTH 2023. [PMID: 37067349 DOI: 10.1922/cdh_00279geddis-regan06] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 01/26/2023] [Indexed: 04/18/2023]
Abstract
Dementia is a major public health challenge, and its impact on oral health and oral healthcare delivery can be drastic. More people are living with dementia, and the proportion of people living longer is growing. This review summarises dementia and its impact on oral health, dental care access and dental services. People living with dementia (PLwD) face a substantial risk of developing oral diseases and experiencing orofacial pain. PLwD face many barriers to dental care. When care is accessed, there can be practical and ethical challenges in receiving person-centred treatment. PLwD with the most complex needs are increasing in number and more are likely to require specialist care. Recommendations are made regarding preventative care, dental care access, domiciliary care, workforce planning and treatment decision-making. Those commissioning and facilitating dental care for PLwD should ensure that suitably trained staff are available in accessible services to plan the necessary care and provide active treatment where appropriate. It is almost inevitable that more care will need to be commissioned to support this growing patient group. This need should be anticipated and planned for at a population and policy level to reduce the detrimental impacts of oral diseases and orofacial pain for PLwD.

Older patients' perception of treating root caries with silver diamine fluoride - a qualitative study based on the Theoretical Domains Framework. J Dent 2023; 130:104408. [PMID: 36626976 DOI: 10.1016/j.jdent.2022.104408] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 12/15/2022] [Accepted: 12/29/2022] [Indexed: 01/09/2023] Open
Abstract
OBJECTIVES Caries treatment with silver diamine fluoride (SDF) is effective, but often leads to irreversible tooth discoloration. This study aimed to investigate older patients' perceptions of root caries treatment with SDF and to identify factors that influence their decision process. METHODS Fifteen interviews were conducted in older patients (mean, min/max: 83, 71/92 years) with root caries experience, following a semi-structured interview-guide based on the domains of the Theoretical Domains Framework (TDF) including three case vignettes of SDF treatment. Transcripts of the interviews were used to perform deductive and inductive content analysis along the TDF and Capability-Opportunity-Motivation-Behavior model (COM-B) to assess influential factors. RESULTS All TDF domains and behavior determinants of the COM-B were covered, identifying twenty-two barriers, facilitators and conflicting themes. Main barriers for consenting to SDF treatment were patients' perceptions of permanent staining of visible root caries lesions, as well as preconceptions about those of others and lack of knowledge about root caries and SDF. Main facilitators were trust in advice given by dentists, especially regarding new treatment options, that aesthetics were less important in non-visible areas and the importance of tooth preservation and feasibility of treatments when immobile or in need of care. CONCLUSION Permanent discoloration is an important barrier to older patients' acceptance of SDF treatment for visible root caries. However, patients appear to accept SDF treatment under certain conditions, including less visible lesions or in comparison to more invasive treatment options. CLINICAL SIGNIFICANCE Our findings contribute to understanding both barriers and facilitators when treating root caries in older patients with SDF.

Accuracy of different approaches for detecting proximal root caries lesions in vitro. Clin Oral Investig 2023; 27:1143-1151. [PMID: 36112228 PMCID: PMC9985551 DOI: 10.1007/s00784-022-04709-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 09/05/2022] [Indexed: 11/25/2022]
Abstract
OBJECTIVES The objective was to evaluate the diagnostic accuracy of radiographic evaluation (XR), visual-tactile assessment (VT), laser-fluorescence (LF) (DIAGNOdent Pen/KaVo), and near-infrared-light transillumination (NILT) (DIAGNOcam/KaVo) on proximal root caries lesions in vitro. METHODS Two-hundred extracted permanent premolars and molars with and without proximal root caries lesions were allocated to 50 diagnostic models simulating the proximal contacts between teeth and mounted in a phantom dummy head. Two independent examiners used the diagnostic approaches to detect any or advanced root caries lesions, with histologic evaluation of the lesions serving as reference. Receiver operating characteristic (ROC) curves were employed, and sensitivity, specificity, and the area under the ROC curve (AUC) are calculated. Significant differences in mean AUCs between approaches were assumed if p < 0.05 (two-sample t-test). RESULTS NILT was not applicable for proximal root caries detection. The sensitivity/specificity to detect any lesions was 0.81/0.63 for XR, 0.76/0.88 for VT and 0.81/0.95 for LF, and the sensitivity/specificity to detect advanced lesions was 0.43/0.94 for XR, 0.66/0.99 for VT, and 0.83/0.78 for LF, respectively. For both, any and advanced root caries lesions, mean AUCs for LF and VT were significantly higher compared to XR (p < 0.05). For any root caries lesions, LF was significantly more accurate than VT (p = 0.01), but not for advanced root caries lesions (p = 0.59). CONCLUSIONS Under the in vitro conditions chosen, LF and VT were more accurate than XR to detect proximal root caries lesions, with LF being particularly useful for initial lesion stages. CLINICAL RELEVANCE LF might be a useful diagnostic aid for proximal root caries diagnosis. Clinical studies are necessary to corroborate the findings.

Self-rated oral health among elderly patients attending a university dental hospital in Thailand: a telephone-based cross-sectional survey study. PeerJ 2022; 10:e14191. [PMID: 36248702 PMCID: PMC9558616 DOI: 10.7717/peerj.14191] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 09/15/2022] [Indexed: 01/24/2023] Open
Abstract
Background Oral health perception is an influential predictor of both current and future health among the elderly. However, limited research has focused on self-rated oral health among older patients attending tertiary dental care. Therefore, this study aimed to explore the potential factors associated with self-rated oral health among elderly patients attending a university dental hospital in Thailand. Methods This telephone-based cross-sectional study was carried out among elderly patients older than 60 years who attended at least one dental visit at the university dental hospital in 2020. Hospital numbers (HN) were used to identify eligible candidates for this study. We calculated the sample size by assuming a finite population of 70,028 elderly patients with valid telephone numbers. The minimum sample required for this study was 398 participants. Trained interviewers conducted telephone calls between July 2021 and January 2022 using the validated modified oral health questionnaire. Self-rated oral health was assessed using a conventionally used global oral health question: "How would you describe your dental health?" with three response options: good, fair, and poor. Descriptive statistics, Fisher's exact test, and binary logistic regression were performed to analyze the data. Results A total of 836 telephone numbers were called. There were 402 (48.10%) elderly patients who agreed to and completed the telephone interview. Most of the study participants were women (61.4%) between 61-74 years of age (83.1%) with a mean age of 69.18 years. Bivariate analyses showed associations between poor self-rated oral health and lower subjective oral functions: chewing discomfort (p < 0.001) and speaking discomfort (p = 0.013). However, the multivariate regression model indicated a significant association between poor self-rated oral health and chewing discomfort (p < 0.001). Therefore, elderly patients with chewing discomfort were more likely to perceive poor oral health. Conclusions These findings indicate that difficulty chewing could be a potential factor influencing self-rated adverse oral health among older patients attending the university dental hospital. Furthermore, our study adds that the predictive power of a single-item self-measurement supports its value as a standard measure to predict oral health risk in tertiary care institutions, as well as primary care settings and community-based survey research. Therefore, healthcare providers should routinely evaluate self-rated oral health among elderly patients to detect early signs and symptoms of oral health problems, assess the success of dental treatments, and monitor general health and well-being.

Generalizability and reach of a randomized controlled trial to improve oral health among home care recipients: comparing participants and nonparticipants at baseline and during follow-up. Trials 2022; 23:560. [PMID: 35804423 PMCID: PMC9264743 DOI: 10.1186/s13063-022-06470-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Accepted: 06/09/2022] [Indexed: 11/13/2022] Open
Abstract
Background The generalizability of randomized controlled trials (RCTs) with a low response can be limited by systematic differences between participants and nonparticipants. This participation bias, however, is rarely investigated because data on nonparticipants is usually not available. The purpose of this article is to compare all participants and nonparticipants of a RCT to improve oral health among home care recipients at baseline and during follow-up using claims data. Methods Seven German statutory health and long-term care insurance funds invited 9656 home care recipients to participate in the RCT MundPflege. Claims data for all participants (n = 527, 5.5% response) and nonparticipants (n = 9129) were analyzed. Associations between trial participation and sex, age, care dependency, number of Elixhauser diseases, and dementia, as well as nursing, medical, and dental care utilization at baseline, were investigated using multivariable logistic regression. Associations between trial participation and the probability of (a) moving into a nursing home, (b) being hospitalized, and (c) death during 1 year of follow-up were examined via Cox proportional hazards regressions, controlling for baseline variables. Results At baseline, trial participation was positively associated with male sex (odds ratio 1.29 [95% confidence interval 1.08–1.54]), high (vs. low 1.46 [1.15–1.86]) care dependency, receiving occasional in-kind benefits to relieve caring relatives (1.45 [1.15–1.84]), having a referral by a general practitioner to a medical specialist (1.62 [1.21–2.18]), and dental care utilization (2.02 [1.67–2.45]). It was negatively associated with being 75–84 (vs. < 60 0.67 [0.50–0.90]) and 85 + (0.50 [0.37–0.69]) years old. For morbidity, hospitalizations, and formal, respite, short-term, and day or night care, no associations were found. During follow-up, participants were less likely to move into a nursing home than nonparticipants (hazard ratio 0.50 [0.32–0.79]). For hospitalizations and mortality, no associations were found. Conclusions For half of the comparisons, differences between participants and nonparticipants were observed. The RCT’s generalizability is limited, but to a smaller extent than one would expect because of the low response. Routine data provide a valuable source for investigating potential differences between trial participants and nonparticipants, which might be used by future RCTs to evaluate the generalizability of their findings.

Abstract
AIM The purpose of this review is to compare randomized clinical trials evaluating the peri-implant tissue outcomes using different unsplinted attachment systems in two implant-retained mandibular overdentures. BACKGROUND Literature lacks information on various unsplinted attachment systems and their effect on peri-implant tissue health. A focus question (as per PICOS) was set as follows: Does one particular unsplinted attachment system (I) compared with another (C) results in better peri-implant outcomes (O) in two implant-retained mandibular overdentures (P) using randomized controlled trials (RCTs) (S)? The literature search was conducted in the PubMed, MEDLINE and Cochrane Central Register of Controlled Trials (CENTRAL) databases between January 2011 and December 2021. The keywords used were "denture, overlay," "denture," "overlay" AND "dental prosthesis, implant supported," "dental implants," "dental implant abutment design" AND "jaw, edentulous," "mouth, edentulous" AND "mandible." Only RCTs on two implant-retained mandibular overdentures using unsplinted attachment systems measuring peri-implant tissue outcomes with minimum 1-year follow-up were selected. In total, 224 studies were identified in initial search, and 25 were shortlisted for full-text evaluation. Four studies were included for systematic review upon considering inclusion and exclusion criteria. The risk of bias was evaluated using Cochrane Risk of Bias Tool 2.0 (RoB 2.0). REVIEW RESULTS A total of 41 patients received ball attachments (in 3 studies), 36 patients received low-profile attachments (in 3 studies), 16 patients received magnet attachments (in 1 study), and 13 patients received telescopic attachments (in 1 study). All four studies used standard sized implants, however, differed in implant manufacturers. Two studies which compared ball attachments low-profile attachments revealed-similar peri-implant tissue health parameters but differed in crestal bone-level changes. One study compared ball with telescopic attachments and revealed similar results in crestal bone-level changes and all four peri-implant tissue health parameters. Single study compared magnets with low-profile attachments and shown lesser bone loss with magnet attachments. Single study was judged to have low risk of bias, single with some concerns, and remaining two to have high risk of bias. CONCLUSION Gingival index and bleeding index of the patients were not influenced by any of the unsplinted overdenture attachment (stud, magnet, telescopic) system. Inconclusive results found among the studies evaluated comparing crestal bone loss and plaque index. CLINICAL SIGNIFICANCE This review manuscript has simplified comparative analysis of different unsplinted attachment systems used in two implant mandibular overdentures to help clinicians choose correct system in such situation.

CAD-CAM complete removable dental prostheses: A double-blind, randomized, crossover clinical trial evaluating milled and 3D-printed dentures. J Dent 2021; 115:103842. [PMID: 34637889 DOI: 10.1016/j.jdent.2021.103842] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 09/28/2021] [Accepted: 10/01/2021] [Indexed: 11/29/2022] Open
Abstract
OBJECTIVE This double-blind, randomized, crossover, clinical trial aimed to evaluate and compare the differences between milled and 3D-printed complete removable dental prostheses (CRDPs). METHODS Fifteen edentulous patients (men: n = 10, women: n = 5; age: 66.7 ± 8.0 years) rehabilitated with conventional CRDPs were recruited for this trial. Participants were randomized to first receiving either the milled or 3D-printed CAD-CAM manufactured CRDPs and then after 6-weeks cross over to the other set. Both, clinicians and participants were blinded to the group allocation. Outcomes included patient's denture satisfaction (PDS), oral-health related quality of life (OHIP-EDENT), willingness-to-pay analysis, final choice (FC) of CRDPs, clinician's denture quality evaluation (CDQE), chewing efficiency (CE), maximum-voluntary-bite-force (MBF), and prosthodontic maintenance needs. The outcomes were measured at baseline (with old CRDPs), at 1 and 6 weeks after new CRDP insertion; following crossover with the second set of CRDPs, an identical protocol was followed. Generalized linear regression for repeated measures was used for statistical analysis with α=0.05. RESULTS All participants completed the trial. 3D-printed CRDPs required more maintenance visits, adjustment time (p = 0.0003), and adjustment costs (p = 0.021). Patients were willing-to-pay an average of 606.67 Swiss Francs more than the actual cost for the milled CRDPs. There were no differences in the PDS, OHIP, FC, CDQE, CE, and MBF between the two CRDPs groups. CONCLUSIONS The findings of this double-blind randomized crossover clinical trial confirm that both milled and 3D-printed CRDPs are valid treatment modalities for edentulous patients, with the latter performing inferiorly with regard to the time and costs involved with the prosthodontic aftercare, as well as the patients' willingness-to-pay. CLINICAL RELEVANCE The findings of this trial provide evidence to help the clinician in choosing the appropriate CAD-CAM manufacturing process for fabricating the CRDPs.

Effect of Isometric Tongue Lifting Exercise on Oral Function, Physical Function, and Body Composition in Community-Dwelling Older Individuals: A Pilot Study. Gerontology 2021; 68:644-654. [PMID: 34515122 DOI: 10.1159/000518270] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 07/04/2021] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION It is known that oral frailty is one of the risk factors for physical frailty. Therefore, early detection, appropriate treatment, and prevention of oral frailty are really important. Tongue lifting exercise has been identified as a well-known method for improving decreased tongue pressure, one of the factors for oral frailty. However, few reports have investigated how tongue-strengthening exercises affect physical function and body composition. The aim of this study was to investigate the effects of isometric tongue lifting exercises on oral function, physical function, and body composition. METHODS Participants were 49 elderly people aged 68-79 years, who had previously participated in the "Itoshima Frail Study." Participants performed isometric tongue lift exercises for 3 months. Oral function (tongue pressure and oral diadocokinesis), physical function (grip strength, open-eyed one-leg standing, sit-to-stand motion time, 5-m gait speed, and 3-m Timed up and go [TUG]), and body composition were measured at baseline and post-intervention, and the extent of changes in each item was statistically analyzed. Furthermore, participants were divided into physical frailty/pre-frailty and robust groups based on the Japanese version of the frail scale proposed by [BMC Geriatr. 2015 Apr;15:36] and were compared in terms of the extent of changes in each item baseline and the post-intervention. RESULTS After the intervention, oral function increased significantly together with a significant improvement in physical function, open-eyed one-leg standing time, sit-to-stand motion, and 3-m TUG. For body composition, visceral fat level and basal metabolic rate decreased significantly. Although no significant change in body composition was observed in the physical frailty/pre-frailty group after the intervention, significant improvements in several items were observed in the robust group. CONCLUSION Isometric tongue lifting exercise can effectively improve oral function. Furthermore, it might affect physical function and body composition.

CAD-CAM complete denture resins: an evaluation of biocompatibility, mechanical properties, and surface characteristics. J Dent 2021; 114:103785. [PMID: 34419480 DOI: 10.1016/j.jdent.2021.103785] [Citation(s) in RCA: 39] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 08/10/2021] [Accepted: 08/13/2021] [Indexed: 10/20/2022] Open
Abstract
OBJECTIVES This study evaluated the biocompatibility, mechanical properties, and surface roughness of CAD-CAM milled and rapidly-prototyped/3D-printed resins used for manufacturing complete dentures. METHODS Six groups of resin specimens were prepared, milled-base (MB), milled-tooth shade (MT), printed-tooth shade (PT), printed-base with manufacturer-recommended 3D-printer (PB1), printed-base with third-party 3D-printer (PB2), printed-base in a vertical orientation (PB2V). Human epithelial (A-431) and gingival (HGF-1) cells were cultured and tested for biocompatibility using Resazurin assays. Three-point bending and nanoindentation tests measured the mechanical properties of the resin groups. Surface roughness was evaluated using a high-resolution laser profilometer. ANOVA and post-hoc tests were used for statistical analyses (α = 0.05). RESULTS There were no significant differences in biocompatibility between any of the investigated groups. MB revealed a higher ultimate strength (p = 0.008), elastic modulus (p = 0.002), and toughness (p = 0.014) than PB1. MT had significantly higher elastic modulus than PT (p < 0.001). Rapidly-prototyped resin samples with a manufacturer-recommended 3D-printer (PB1) demonstrated higher ultimate strength (p = 0.008), elastic modulus (p < 0.001), hardness (p < 0.001) and a reduced surface roughness (p < 0.05) when compared with rapidly-prototyped groups using a third-party 3D-printer (PB2). Rapidly-prototyped samples manufactured with a vertical printing orientation (PB2V) revealed a significantly lower elastic modulus than samples groups manufactured using horizontal printing orientation (PB2) (p = 0.011). CONCLUSIONS Within the limits of this present study, CAD-CAM milled and rapidly-prototyped complete denture resins performed similarly in terms of biocompatibility and surface roughness. However, the milled denture resins were superior to the rapidly-prototyped denture resins with regard to their mechanical properties. Printing orientation and type of 3D-printer can affect the resin strength and surface roughness.

CAD-CAM removable complete dentures: A systematic review and meta-analysis of trueness of fit, biocompatibility, mechanical properties, surface characteristics, color stability, time-cost analysis, clinical and patient-reported outcomes. J Dent 2021; 113:103777. [PMID: 34400250 DOI: 10.1016/j.jdent.2021.103777] [Citation(s) in RCA: 45] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Revised: 08/02/2021] [Accepted: 08/06/2021] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVES This review compared Computer-aided designand Computer-aided manufactured (CAD-CAM) and conventionally constructed removable complete dentures (CDs). DATA Seventy-three studies reporting on CAD-CAM (milled/3D-printed) CDs were included in this review. The most recent literature search was performed on 15/03/2021. SOURCES Two investigators searched electronic databases [PubMed (MEDLINE), Embase, CENTRAL], online search engines (Google) and research portals. Hand searches were performed to identify literature not available online. STUDY SELECTION Studies on CAD-CAM CDs were included if they reported on trueness of fit, biocompatibility, mechanical, surface, chemical, color , microbiological properties, time-cost analysis, and clinical outcomes. Inter-investigator reliability was assessed using kappa scores. Meta-analyses were performed on the extracted data . RESULTS The kappa score ranged between 0.897-1.000. Meta-analyses revealed that 3D-printed CDs were more true than conventional CDs (p = 0.039). Milled CDs had a higher flexural-strength than conventional and 3D-printed CDs (p < 0.0001). Milled CDs had a higher flexural-modulus than 3D-printed CDs (p < 0.0001). Milled CDs had a higher yield-strength than injection-molded (p = 0.004), and 3D-printed CDs (p = 0.001). Milled CDs had superior toughness (p < 0.0001) and surface roughness characteristics (p < 0.0001) than other CDs . Rapidly-prototyped CDs displayed poor color-stability compared to other CDs (p = 0.029). CAD-CAM CDs d displayed better retention than conventional CDs (p = 0.015). Conventional CDs had a higher strain at yield point than milled CDs (p < 0.0001), and had superior esthetics than 3D-printed (p < 0.0001). Fabrication of CAD-CAM CDs required less chairside time (p = 0.037) and lower overall costs (p < 0.0001) than conventional CDs. CONCLUSIONS This systematic review concludes that CAD-CAM CDs offer a number of improved mechanical/surface properties and are not inferior when compared to conventional CDs. CLINICAL SIGNIFICANCE CAD-CAM CDs should be considered for completely edentulous patients whenever possible, since this technique offers numerous advantages including better retention, mechanical and surface properties but most importantly preserves a digital record. This can be a great advantage for older adults with limited access to dental care.

Denture-related problems of patients in acute geriatric care. Z Gerontol Geriatr 2021; 55:318-324. [PMID: 34170352 PMCID: PMC9213273 DOI: 10.1007/s00391-021-01928-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 05/19/2021] [Indexed: 10/26/2022]
Abstract
BACKGROUND With increasing frailty and complaint-oriented utilization of dental care, the prevalence of oral diseases also increases. AIM To clarify whether there is a need for dental prosthodontic treatment during residential acute geriatric rehabilitation. METHODS Within 3 weeks in a hospital for acute geriatric patients, 79 out of 157 newly admitted patients were interviewed as study participants (age: median 79.0 years, range 66-96 years, female 51.9%), dental findings were recorded, treatment needs were determined but X‑rays were not taken. RESULTS Of the participants 31.1% had not seen a dentist for more than 1 year and 18.2% were edentulous. The median number of teeth in dentate participants was 16 (range 1-28 teeth); based on all participants, there was a median of 12.0 teeth (range 0-28 teeth). Of the 52 denture wearers (45 upper jaw and 43 lower jaw), 5 each of the maxillary and mandibular dentures could not be assessed because they were not available at the hospital. Moderate denture deficiencies were present in 62.5% of participants wearing upper dentures (mandibular 55.3%). CONCLUSION Dental treatment is needed in this vulnerable patient group. Therefore, the oral cavity should be assessed as part of the geriatric assessment. The available data confirm that the use of validated assessment instruments, such as the mini dental assessment as part of the comprehensive geriatric assessment would be useful. In addition to an oral examination, simple dental treatment should be provided to reduce infections and improve chewing ability. The geriatrician should be informed of the urgency of treatment. The overall rehabilitative approach of acute geriatric treatment would be complete if oral health would not be excluded.

Abstract
Die Mundgesundheit der Bevölkerung in Deutschland konnte in den letzten Jahren verbessert werden; allerdings profitierten ältere und insbesondere gebrechliche sowie pflegebedürftige Menschen nicht adäquat von dieser Entwicklung. Dabei kann eine gute Mundgesundheit relevant dazu beitragen, die Herausforderungen bei Gebrechlichkeit und Pflegebedürftigkeit besser zu bewältigen. Der eingeschränkte Zugang zur zahnmedizinischen Betreuung, die manchmal eingeschränkte Kooperativität sowie die schlechtere Mundpflege in dieser Bevölkerungsgruppe erhöhen das Risiko für Karies, Parodontalerkrankungen, Zahnverlust und Zahnlosigkeit im Vergleich zur Durchschnittsbevölkerung. Der vorliegende Beitrag gibt eine Übersicht über die zahnmedizinische Situation älterer Menschen anhand bereits publizierter Daten aus der bevölkerungsrepräsentativen Fünften Deutschen Mundgesundheitsstudie (DMS V), die im Jahr 2014 erhoben wurden. Die mittlere Anzahl der fehlenden Zähne betrug bei den 65- bis 74-Jährigen 11,1 Zähne. Bei älteren Seniorinnen und Senioren (75–100 Jahre) mit Pflegebedarf (äSmP) war die Mundgesundheit schlechter als bei denjenigen ohne Pflegebedarf (äSoP). So hatten äSoP durchschnittlich 11,8 Zähne, äSmP dagegen nur 5,7 Zähne. Der Anteil zahnloser 65- bis 74-Jähriger hatte sich seit 1997 halbiert auf 12,4 %. Bei den äS waren 32,8 % zahnlos (äSmP: 53,7 %, äSoP: 26,7 %). Mehr als 75 % der äSmP waren abnehmbar prothetisch versorgt (äSoP: 51,7 %). Vor diesem Hintergrund werden in diesem Beitrag Schnittstellen benannt, an denen eine chancengleiche Anbindung dieser Bevölkerungsgruppen an eine zahnmedizinische Versorgungsstruktur etabliert werden könnte. Diese beinhalten akutgeriatrische Krankenhausstationen und die Entwicklung weitergehender Konzepte in der aufsuchenden Versorgung zur besseren Versorgung der Betroffenen und zur Erleichterung der Pflege.

Abstract
This systematic review was undertaken to address the PICO question: Is silver diamine fluoride (SDF) effective in preventing and arresting root caries lesions in (RCLs) elders? Systematic literature searches were conducted of electronic databases [PubMed, Embase, and CENTRAL (Cochrane Controlled Register of Trials)] and hand searches were performed to identify studies reporting on the use of SDF in elders to prevent and arrest root caries. Prospective clinical studies were included. Two independent investigators performed the literature search and data extraction. A total of 277 studies were identified; of those 3 randomized controlled clinical trials were included for data extraction and analysis. A meta-analysis, using a fixed-effects model, was performed on the mean active RCLs present after SDF intervention compared to controls at 24 months (3 studies), and 30-36 months (2 studies) post-intervention. The fixed-effects model revealed a significant decrease in the mean new active RCLs post intervention with SDF compared to controls at both 24 months (95%CI: 0.265 - 0.638; I2=0.0%; Overall: Z=4.749, p<0.001), and at 30-36 months (95%CI: 0.329 - 0.812; I2=0.0%; Overall: Z=4.629, p<0.001). A funnel plot ruled out any publication bias and the risk of bias was judged to be low. This systematic review and meta-analysis provides evidence that the application of silver diamine fluoride prevents and arrests root caries in elders.

Factors Associated with Denture Non-use in Older Adults Requiring Long-Term Care. Arch Gerontol Geriatr 2021; 95:104412. [PMID: 33823472 DOI: 10.1016/j.archger.2021.104412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 03/10/2021] [Accepted: 03/27/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Evidence suggests that denture non-use is significantly associated with activities of daily living, oral function, and cognitive decline. Few studies have focused on the possibility that the indications for denture use may differ depending on the cognitive and physical functions in older adults requiring long-term care. OBJECTIVES The aim of this study was to elucidate the factors associated with denture non-use in older adults requiring long-term care. METHODS This cross-sectional study comprised 201 older adults (45 men and 156 women; average age = 86.2 ± 7.1 years) requiring long-term care in Japan. Those who did not require denture treatment were classified by dentists into denture-use and denture non-use groups. The severity of dementia was assessed using the Clinical Dementia Rating scale. Multiple logistic regression analyses were conducted to detect the factors significantly associated with denture non-use. RESULTS The proportion of participants without dentures was 58.2%. Multiple logistic regression analyses revealed that a moderate dementia (odds ratio [OR], 4.44; 95% confidence interval [CI] 1.18-16.71, p=0.027) and rinsing ability (OR 3.00; 95% CI 1.12-8.06; p=0.030) were significant factors related to the non-use of dentures. CONCLUSION Severity of dementia and rinsing ability were significantly associated with non-use of dentures. These findings indicate the necessity of evaluating oral and cognitive functions while planning denture treatment in older adults requiring long-term care.

Abstract
Older adults have multiple morbidities that can impact oral, systemic, and psychological health. Although each disorder requires consideration from the provider before treatment, by assessing the common phenotypic presentations of older adults, we can better understand, select, and coordinate treatment modifications that would need to be considered and implemented for dental care.

Abstract
The purpose of this questionnaire-based survey was to evaluate the attitudes of the undergraduate dental students towards elders. The 14-item Geriatric attitudes scale (GAS) questionnaire, along with a 9-item questionnaire with specific questions on the current geriatric dental curriculum, confidence, and preference in treating the elderly patients were administered to the undergraduate dental students (3rd bachelor, 1st master, and 2nd master) in the four Swiss university dental schools. Mean GAS scores were calculated and inter- and intra-group differences were analyzed with ANOVA and post hoc tests (level of significance set at α=0.05). Responses to the 9-item questionnaire were reported descriptively. Further analyses were performed to evaluate the effect of demographic factors on the GAS scores. 305 students (meanage: 25.8±4.0y) participated in this study. The mean overall GAS score of the students was 3.5±0.4. There were no significant differences in the GAS scores between the centers [F(3, 300)=2.266, p=0.081] or between the year of training [F(2, 301)=1.884, p=0.154]. Demographic factors did not influence the GAS scores. Students considered geriatric dentistry as an important part of their dental undergraduate education. The current geriatric curriculum was perceived to be on an adequate level. Hands-on experience in treating geriatric patients in the undergraduate curriculum was positively opinionated, and mobile dental services for elders with limited access to care was considered a good solution. In conclusion, the attitudes of the Swiss undergraduate dental students towards an elderly patient seem acceptable but could still be improved.

A prediction model of masticatory performance change in 50- to 70-year-old Japanese: The Suita study. J Dent 2020; 104:103535. [PMID: 33207241 DOI: 10.1016/j.jdent.2020.103535] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 10/26/2020] [Accepted: 11/12/2020] [Indexed: 01/22/2023] Open
Abstract
OBJECTIVES Declines in masticatory performance might be a risk factor for worsening nutritional intake and result in general frailty. The present study constructed and investigated a method to predict the extent to which objective masticatory performance declines with age in cases with poor oral health status. METHODS Participants comprised 1201 participants in the Suita study with dental checkup at both baseline and follow-up (500 men and 701 women; age at baseline, 65.6 ± 7.8 years; mean follow-up, 5.1 ± 1.1 years). First, multiple linear regression analysis was performed with masticatory performance at follow-up as the dependent variable and sex as well as baseline age, number of functional teeth, maximum bite force, occlusal support, periodontal status, salivary flow rate, and masticatory performance as independent variables. Scores were assigned to each factor based on the standardized partial regression coefficient obtained from multiple linear regression analysis. Participants were divided into quintile groups (Q1-Q5) based on total scores for factors, and rates of masticatory performance change for each group were calculated and compared. RESULTS Mean rates of masticatory performance change in groups Q1-Q5 from the model to predict declining masticatory performance were: Q1, -9.7%; Q2, -12.7%; Q3, -18.0%; Q4, -19.9%; and Q5, -29.8%.Thus there was a trend for masticatory performance to decrease with decreasing score. CONCLUSIONS The model developed in this study quantitatively predicted declines in masticatory performance after approximately 5 years. CLINICAL SIGNIFICANCE We developed a model for predicting the extent to which masticatory performance will change over the next 5 years. This model may offer a useful tool when taking measures to prevent declines in masticatory performance with aging.

Abstract
Hintergrund Einschränkungen der Mundgesundheit ambulant betreuter Senioren in Deutschland werden trotz hoher Prävalenz im hausärztlich-geriatrischen Bereich nicht routinemäßig erfasst. Da Senioren Hausärzte mit höherem Alter häufiger aufsuchen als Zahnärzte, stellt sich die Frage, ob reduzierte Mundgesundheit im Praxisalltag mit einem interdisziplinären Screeninginstrument identifiziert werden kann. Ziel der Arbeit Ziel der Arbeit ist, ein Screeninginstrument für reduzierte Mundgesundheit für Hausärzte zu entwickeln und dieses durch zahnmedizinische Befunde zu validieren. Material und Methoden Das geriatrische ambulante Mundgesundheits-Screening (GAMS) als subjektives Screeninginstrument wurde entwickelt, um für geriatrische Patienten relevante zahnmedizinische Aspekte wie Kauprobleme, Schmerzen, Parodontitis, Mundgeruch oder Mundtrockenheit in dichotomen Fragen abzubilden. Zudem erfolgt die Einschätzung der Dringlichkeit eines Zahnarztbesuches durch den Behandler. Es wurden n = 75 Patienten eingeschlossen und der GAMS sowie eine zahnärztliche Untersuchung zur Validierung durchgeführt. Ergebnisse Bei subjektiver Einschätzung als auch im zahnmedizinischen Befund zeigte sich reduzierte Mundgesundheit, insbesondere bei Risikofaktoren für die Entwicklung systemischer Komorbiditäten wie Dysphagie und Mangelernährung, wobei Mundgesundheitsprobleme durch die Patienten unterschätzt wurden. Einbisse, Kauschwierigkeiten und Mundtrockenheit zeigten ausreichende Übereinstimmung zwischen oralem Befund und subjektiver Einschätzung. Diskussion Der GAMS könnte beitragen, die Erwägung und Berücksichtigung von Mundgesundheitsproblemen bei geriatrischen Patienten im hausärztlichen Setting zu erleichtern und die Zusammenarbeit mit Zahnmedizinern im Sinne europäischer Handlungsempfehlungen fördern.

Special care dentistry in a charity clinic: Demographic analysis and barriers to care in Singapore. Tzu Chi Med J 2019; 31:232-239. [PMID: 31867251 PMCID: PMC6905231 DOI: 10.4103/tcmj.tcmj_101_18] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Revised: 06/28/2018] [Accepted: 09/30/2018] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVE Geriatric and special care dentistry (GSD) aims to improve oral health of seniors or adults disabilities facing barriers to care. This is coherent with the philosophy of "compassion relief." Tzu Chi Singapore's Free Clinic exemplifies this through promoting health via various avenues to reach out. This article aims to provide a demographic analysis of patients with special care needs (PSCN), including age, gender, race, medical diagnoses, and treatment rendered. The patients were appraised on their complexity with the British Dental Association case mix model. MATERIALS AND METHODS PSCN seen by a dentist in Tzu Chi Singapore from November 2016 to December 2017 were recorded. The profiling of patients was done retrospectively. RESULTS Fifty-five dental PSCN were treated over 82 visits. 58.2% were seen in the free clinic, 27.3% in nursing homes, and 14.5% in oral health day programs for adults with intellectual disability. Their average age was 61.2 years, and the clinic was attended by patients of different races. Their medical profiles were grouped into seven categories, and the average case mix total banded score was 21.6, indicating that the average patient had "severe complexity". A few themes relevant to Singapore were discussed, such as specialist GSD clinics, accessing dental services, socioeconomic status, state versus charity healthcare, and provision of future GSD services. CONCLUSIONS Charity dental services such as free clinic can capture a niche of complex patients who may become marginalized in an established public healthcare.

Abstract
BACKGROUND In the future there will be an increasing demand for professional care with simultaneous retention of the dentition in older people. Due to inadequate dental knowledge, it is often not possible for caregivers to adequately assess dental deficits. OBJECTIVE The aim of the study was to develop and validate a simple tool (Mini Dental Assessment, MDA) to assess possible dental treatment needs (DTN) of residential geriatric facilities by nursing personnel. MATERIAL AND METHODS In the study 169 patients (51 from the University Hospital Giessen, 118 from the Bonifatius Hospital Lingen) underwent a dental examination. The dental status was evaluated based on the California Dental Association (CDA) criteria and the DTN determined. In addition, the time since the patients last visit to a dentist (TLVD) and denture age (DA) were documented and a chewing function test (carrot eating test, CET) was carried out. In a second study 155 patients were examined (115 from the University Hospital Giessen, 40 from the Bonifatius Hospital Lingen) corresponding to the reference sample and including a further chewing function test (after Schimmel und Slavicek) and questionnaires on quality of life (Oral Health Impact Profile (OHIP), Denatl Impact on Daily Living (DiDDL)). RESULTS A total of 108 patients required dental treatment. The mean value (±SD) for the TLVD was 2.5 ± 3.8 years and 10.8 ± 8.9 years for the DA. There was a positive correlation (Spearman, P < 0.005) between the DTN and degree of comminution in the CET (3.4 ± 1.8 grade). Based on the results an assessment tool was developed using the variables CET, TLVD and DA weighted by the respective regression coefficients (10:3:1). The resulting mean total MDA score was 51.32 ± 28.14. A sensitivity/specificity analysis was conducted and a receiver operating characteristic (ROC) curve calculated (area under curve, AUC: 0.805; 95% CI: 0.738-0.873). The ROC curve from the follow-up study showed a good agreement with the ROC curve from the reference study (AUC 0.829, 95% CI: 0.751-0.907). CONCLUSION Based on the results of the study it could be shown that the MDA is a suitable instrument for making a valid statement on the assessment of DTN of patients in long-term care facilities. The validation study revealed the validity of the MDA in its originally developed form and the addition of two further chewing function tests did not significantly improve the validity of the MDA. Overall, the MDA appears to be an appropriate tool to help nursing home personnel to assess the necessity for nursing home residents to visit a dentist.

Abstract
OBJECTIVES Stud attachments are often too adhesive and too susceptible to damage for use in geriatric patients, especially when implants are angulated. This study aimed to evaluate alternative anchoring systems comprising individual and prefabricated polyvinylsiloxane (PVS) attachments. MATERIALS AND METHODS A total of 182 specimens with individual PVS (IPVS) attachments (Shore hardness [SH] 25, SH50, SH65], prefabricated PVS (PPVS) attachments (SM green, yellow, and red), and Locator attachments (LR blue) were fabricated (n = 7 per group). Retention force was measured using the following parameters: insertion/removal (100, 200, 500, 1000, and 5000 cycles), thermal undulation (10,000 cycles at 5-55 °C; one implant per specimen), implant angulation (0°, 5°, and 10° convergence and divergence; two implants per specimen), and artificial saliva. RESULTS Insertion/removal and thermal undulation caused no changes in retention force in SM green and IPVS subgroups; conversely, LR blue, SM red, and SM yellow attachments exhibited significant decreases in retention force of up to 66% (all P ≤ 0.001). Implant angulation produced relevant changes in retention force only in LR blue attachments. Artificial saliva caused a general decrease in retention force. CONCLUSIONS Retention force of low-retentive PVS attachments proved to be comparatively immune to dislocation and thermal undulation, as well as to implant angulation up to 10°. CLINICAL RELEVANCE Low-retentive PVS attachments could be a treatment option if reduced denture retention is required and/or if angulated implants are in place. Clinical studies are necessary to evaluate the materials' durability under oral conditions.

Abstract
AIMS The aim of the study was to assess the extent to which a relationship may exist between the wear of the anterior teeth and quality of life in a population of nursing home residents. METHODS AND RESULTS A population (n = 100) of nursing home residents (mean age 75.7 years) was recruited all members of which had at least 4 upper and 4 lower anterior teeth and were assessed as cognitively intact by nursing personnel who were familiar with their behavior. The investigator evaluated the level of tooth wear of each subject according to the Tooth Wear Index of Donachie and Walls (Adapted) and then verbally administered the Geriatric Oral Health Assessment Index (GOHAI) of Atchison and Dolan. Analyses did not reveal significant differences in tooth wear between males and females nor between age and GOHAI score; however, tooth wear was positively related to age and inversely related to quality of life. CONCLUSIONS Results suggest that tooth wear is negatively related to quality of life.

Abstract
Implant therapy is gaining presence as a prosthodontic treatment option. However, the graying of the population has led to an increase in the number of older adults requiring special consideration in implant treatment because of their systemic health problems. Additionally, with the growth of the elderly population in need of long-term care, a greater number of older adults who have received implant treatment are receiving long-term care, raising various issues that need to be addressed. In the present review article, we describe the significance of implant treatment in older adults, issues when performing implant treatment in geriatric patients, and measures to be taken when implant patients have lapsed into a state of requiring long-term care. In addition, in view of population aging, we propose an approach for applying implant treatment to older adults. This approach includes using an appropriate type of implant system depending on the remaining life expectancy and the patient's general condition, performing less invasive surgery, providing treatment using prosthetic appliances that are easy to manage and can be modified, and ensuring oral health management by providing an Implant Card to patients when the treatment is completed.

Abstract
The aim of this study was to evaluate Croatian undergraduate students' knowledge based on what they learned in the recent course, as well as the students' own judgment and opinions about geriatric dentistry education concerning temporomandibular disorders (TMDs) of the elderly. The study was carried out by means of a questionnaire administered in the last study year to students of the School of Dental Medicine, University of Zagreb and students of the Department of Dental Medicine at the School of Medicine, University of Rijeka. Th e questionnaire included questions about relevant specific knowledge on TMD, and statements related to their own opinion about geriatric dentistry education received during the study. Regarding students' knowledge related to TMDs, students from Rijeka gave more positive answers (p=0.012). Students from Rijeka gave more positive answers regarding physical therapy for treatment of TMD (p=0.004) and disc displacement and osteoarthritis as the most common disorders of the temporomandibular joint (p=0.031). Students from Zagreb were more unsatisfi ed with the skills in the field of geriatric dentistry (disagreed 57.45%) than students from Rijeka (45.83% had neutral standpoint and 37.50% agreed) (p=0.005). The level of the participants' knowledge pointed to the need of improving undergraduate dental teaching about the specific geriatric education, including knowledge about TMD.

Abstract
INTRODUCTION Edentulous patients often hope for stable and retentive prostheses. In very unfavorable anatomophysiological circumstances, the implant-retained removable full denture is a simple and reliable option that considerably optimizes the prosthetic balance. We present the case of one of those patients taken in charge in our department. OBSERVATION A full edentulous 82 years old male patient was referred for a prosthetic rehabilitation. He presented with a negative mandibular crest and a very tonic peri-prosthetic musculature in the anterior region. He refused a bone augmentation surgery; we performed a piezographic mandibular prosthesis retained by a single symphyseal implant in a lingual position. The denture was stable and retentive. Comfort and masticatory efficiency were satisfactory and the psychological integration of the prosthesis was improved. DISCUSSION Several studies focusing on octogenarian patients concluded that a complete removable denture retained by a single symphyseal implant is a simple, efficient and cost-effective option. Studies including more patients are needed.

Abstract
Oral health for the older adult patient is vital for function, comfort, and communication and is a critical component of overall health. Oral diseases such as dental caries, periodontal disease, and oral cancer may lead to pain, functional limitations, and decreased quality of life. Optimal oral health outcomes are often owing to effective interprofessional collaboration between and among health care providers, in conjunction with patient family members and caregivers. This article highlights 2 cases illustrating how interprofessional team dynamics can affect patient outcomes.

Tooth replacement for partially dentate elders: A willingness-to-pay analysis. J Dent 2016; 53:51-6. [PMID: 27421987 DOI: 10.1016/j.jdent.2016.07.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2015] [Revised: 07/08/2016] [Accepted: 07/11/2016] [Indexed: 01/23/2023] Open
Abstract
OBJECTIVES The primary aim of this study was to investigate partially dentate elders' willingness-to-pay (WTP) for two different tooth replacement strategies: Removable Partial Dentures (RPDs) and, functionally orientated treatment according to the principles of the Shortened Dental Arch (SDA). The secondary aim was to measure the same patient groups' WTP for dental implant treatment. METHODS 55 patients who had completed a previous RCT comparing two tooth replacement strategies (RPDs (n=27) and SDA (n=28)) were recruited (Trial Registration no. ISRCTN26302774). Patients were asked to indicate their WTP for treatment to replace missing teeth in a number of hypothetical scenarios using the payment card method of contingency evaluation coupled to different costs. Data were collected on patients' social class, income levels and other social circumstances. A Mann-Whitney U Test was used to compare differences in WTP between the two treatment groups. To investigate predictive factors for WTP, multiple linear regression analyses were conducted. RESULTS The median age for the patient sample was 72.0 years (IQR: 71-75 years). Patients who had been provided with RPDs indicated that their WTP for this treatment strategy was significantly higher (€550; IQR: 500-650) than those patients who had received SDA treatment (€500; IQR: 450-550) (p=0.003). However patients provided with RPDs indicated that their WTP for SDA treatment (€650; IQR: 600-650) was also significantly higher than those patients who had actually received functionally orientated treatment (€550; IQR: 500-600) (p<0.001). The results indicated that both current income levels and previous treatment allocation were significantly correlated to WTP for both the RPD and the SDA groups. Patients in both treatment groups exhibited little WTP for dental implant treatment with a median value recorded which was half the market value for this treatment (€1000; IQR: 500-1000). CONCLUSIONS Amongst this patient cohort previous treatment experience had a strong influence on WTP as did current income levels. Both treatment groups indicated a very strong WTP for simpler, functionally orientated care using adhesive fixed prostheses (SDA) over conventional RPDs. CLINICAL SIGNIFICANCE Partially dentate older patients expressed a strong preference for functionally orientated tooth replacement as an alternative to conventional RPDs.

Abstract
OBJECTIVE The objective of this study was to develop a simple tool for the assessment of possible dental treatment needs (DTN) for non-dental professionals (Mini Dental Assessment, MDA). To keep the assessment universal, we aimed to base it on the patient's history and a simple chewing efficiency test (CET) as the dental status is a known determinant for chewing efficiency. MATERIALS & METHODS The assessment was developed using data from 169 patients from two sites (University Hospital Giessen, St. Bonifatius Hospital Lingen, both Germany). In all patients, a dental examination was performed, the denture status was evaluated (based on the California Dental Association criteria; CDA criteria), and the DTN was determined. In addition, the time since the patient's last visit to a dentist (TLVD) and denture age (DA) were assessed. Furthermore, a CET was carried out and the comminution score was determined (CETS). RESULTS In total, 108 patients required dental treatment. The mean value (±SD) was 2.9 ± 0.9 score points for the DTN, 2.5 ± 3.8 years for the TLVD, and 10.8 ± 8.9 years for the DA. There was a significant correlation (Spearman, P < .05) between the DTN and degree of comminution (3.4 ± 1.8). Based on the results of the statistical analysis, the intended assessment tool was developed using the variables CETS, TLVD, and DA weighed by their respective regression coefficients (10:3:1). Subsequently, the resulting MDA score (51.32 ± 28.14) was calculated. A sensitivity/specificity analysis was conducted and a receiver operating characteristic curve was calculated (SPSS 17.0, area under curve 0.805; 95 % CI 0.738-0.873). CONCLUSION It can be concluded that the dental status of elderly patients is reflected in the outcome of the MDA. However, ongoing validation is needed. TRIAL REGISTRATION DRKS00003219.

Abstract
Mouth is the mirror of overall health. With advancements in oral health promotion and preventive measures instituted in developed countries, more people retain their natural teeth into their old age as compared to half a century ago. The effect of aging on oral health includes effect on oral mucosa, lips, teeth and other associated structures, and their functional activity leading to impairment of speech, mastication, swallowing and pain leading to anxiety and depression. Oral tissues are not limited to the teeth and supporting structures (periodontium) but also include salivary glands, temporomandibular joint, orofacial/mastication muscles, oropharyngeal mucosa, and oral sensory/motor nerve systems. In India, the second most populous country in the world, there is a rapidly growing population of older adults and there are 70 million elderly people over 60 years of age. Geriatric health problems with respect to the quality of life often remain neglected. Oral health care for an increasingly large segment of elderly people will be a fact of life for dentists everywhere. Oral health can be both a benchmark for and a determinant of the quality of life rather than the length of life span. Older adults are more susceptible to oral conditions or diseases due to an increase in chronic conditions and physical/mental disabilities. Thus, a careful initial interview ensuring that the dentist is familiar with the patient's health history, followed by a thorough oral examination plays a very important role. In this paper, we briefly review the age-related oral changes occurring in geriatric patients and the role of oral physician in imparting a healthy life to the elderly.
