Dental implant considerations in patients with systemic diseases: An updated comprehensive review.

BACKGROUND: Various medical conditions and the drugs used to treat them have been shown to impede or complicate dental implant surgery. It is crucial to carefully monitor the medical status and potential post-operative complications of patients with systemic diseases, particularly elderly patients, to minimize the risk of health complications that may arise. AIM: The purpose of this study was to review the existing evidence on the viability of dental implants in patients with systemic diseases and to provide practical recommendations to achieve the best possible results in the corresponding patient population. METHODS: The information for our study was compiled using data from PubMed, Scopus, Web of Science and Google Scholar databases and searched separately for each systemic disease included in our work until October 2023. An additional manual search was also performed to increase the search sensitivity. Only English-language publications were included and assessed according to titles, abstracts and full texts. RESULTS: In total, 6784 studies were found. After checking for duplicates and full-text availability, screening for the inclusion criteria and manually searching reference lists, 570 articles remained to be considered in this study. CONCLUSION: In treating patients with systemic conditions, the cost-benefit analysis should consider the patient's quality of life and expected lifespan. The success of dental implants depends heavily on ensuring appropriate maintenance therapy, ideal oral hygiene standards, no smoking and avoiding other risk factors. Indications and contraindications for dental implants in cases of systemic diseases are yet to be more understood; broader and hardcore research needs to be done for a guideline foundation.

Implementation of a 4Ms approach in age-friendly oral health care at an Academic Specialty Care Dental Clinic.

BACKGROUND: Implementing the Age-Friendly Health System (AFHS) framework into dental care provides a significant opportunity to link oral health to healthy aging. This project aimed to implement the AFHS 4Ms (what matters, medications, mentation, and mobility) in the provision of oral health care. This article describes the planning, integration, training development, and outcome measurements supporting a 4Ms approach at an academic dental clinic. METHODS: The Eastman Institute for Oral Health (EIOH) implemented screening instruments based on the 4Ms framework recommended for ambulatory care clinics by the Institute for Health Care Improvement (IHI). These ambulatory instruments were integrated into the workflows of a Specialty Care Clinic through the development of a plan-do-study-act cycle, utilization of available clinic resources, and creation of interdisciplinary collaborations. RESULTS: This project demonstrated the feasibility of implementing an AFHS checklist and tracking forms in dental practice by integrating available resources and prioritizing the 4Ms elements. This effort necessitated interdisciplinary collaborations between dental, medical, and social service professionals. It also created a new age-friendly focused education and training curriculum for dental residents and faculty. CONCLUSIONS: This pilot project is the first to establish dental standards for AFHS implementation, adapting the 4Ms assessment and metrics to oral health. This AFHS underscores key oral health processes, including assessment, planning, and personalized oral health care, adapted to the unique needs of the older adult population, especially those with cognitive impairment.

Dental students' reflective learning from a geriatric interview assignment.

OBJECTIVES: As part of geriatric education at the University of British Columbia's Faculty of Dentistry, undergraduate students are required to interview an older adult over 65 years old and critically reflect in writing on the meaning of this interview to themselves and their professional lives in not more than 2000 words. They are also encouraged to use a life grid. This study explored the impact of this assignment on the students as learners and on their views about their profession. METHODS: Interview assignments were collected from the entire cohort of 54 third-year students in 2021 and analyzed in 5 stages, using an exploratory thematic analysis, including an interactive coding process to identify patterns (themes) within the assignments using NVivo R1 software. Two researchers coded assignments individually and met to reach a consensus about the codes, to mitigate potential biases. RESULTS: Five main themes were identified, including communication, life course journey, person-centered care, social determinants of health, and access to care. A wide range of ideas emerged under each theme, including several practical suggestions to improve future practice as an oral health professional. A little over 40% of the students used the life grid in their interviews. Modifications on the interview assignment are suggested. CONCLUSION: Students' reflections highlighted their observations on a wide range of ideas within each theme, many pertaining to their future profession. They also discussed how this knowledge would inform their future practice in terms of their interactions with, and providing care to, patients with similar situations.

Translation and validation of ageism scale for dental students into Malay language.

AIMS: Identifying ageism among dental students is essential in gerodontology courses. This study aimed to perform a preliminary validation of a Malay version of the ageism scale for dental students (ASDS-My). METHODS AND RESULTS: The 27-item ASDS were translated into Malay language and completed by 168 dental students. Exploratory factor analysis (EFA) with Promax rotation, Polychoric Correlation Matrix and Principal Axis Factoring was conducted. Internal consistency reliability and discriminative validity were analysed. Criterion validity was measured by comparing ASDS-My with Fraboni Scale of Ageism (FSA). A Kaiser-Meyer-Olkin of 0.612 and a Bartlett's Test of Sphericity yielding p < .001 confirmed the adequate factorability. EFA revealed a 15-items scale distributed into five-factors explaining 54.5% of overall variance, with acceptable reliability. The two factors involved cost-benefit of dental treatment on older patients and challenges during medical history taking. The third, fourth and fifth factors explained attitude towards older patients, negative views of older patients and exposure of dental students to Gerodontology training and experiences respectively. Most factors were significantly positively related to FSA. Discriminative validity revealed significant differences for gender, place of stay and year of study. CONCLUSION: Preliminary validation of the ASDS-My produced a five-factors 15-items scale with acceptable validity and reliability.

A Proposal for a Multidisciplinary Integrated Oral Health Network for Patients Undergoing Major Orthopaedic Surgery (IOHN-OS).

The passing of the years of life physiologically leads to the accumulation of changes in tissues in the oral cavity, influencing dentition, chewing and swallowing mechanisms, and the oral microbiota. Some diseases and medications can aggravate oral symptoms and negatively influence eating behaviours, increasing the likelihood of becoming malnourished. This could make older individuals more vulnerable to complications when undergoing major orthopaedic surgery. Hidden infection foci in the oral cavity are a recognised cause of post-operative periprosthetic joint infections. Dysfunctional oral problems might also compromise feeding after surgery when good nutrition represents a fundamental aspect of a proper recovery. To manage these shortcomings, in this article, the authors hypothesise a multidisciplinary path of care named the Integrated Oral Health Network applied to major Orthopaedic Surgery (IOHN-OS). This peri-operative initiative would include pre-operative oral health screening and risk management by a dental team, patient education programmes before and after surgery, and bedside gerodontology actions like oral care and meal and eating support for fragile individuals. The IOHN-OS has the potential to reshape the concept of suitability for major orthopaedic surgery and generate momentum for designing community-based surveillance programmes that can keep the mouths of older subjects healthy for a long time.

Survey on the attitudes and perceptions of Swiss dental practitioners and dental students toward treating patients with disabilities and sensory impairments.

AIMS: This study evaluated the attitudes and perceptions of private dental practitioners (PPs) and students on treating patients with disabilities and sensory impairments. METHODS AND RESULTS: A multifaceted questionnaire was used to assess the participants' attitudes on providing care to persons with disabilities and sensory impairments [visual (VI) and hearing (HI)]. The survey evaluated different aspects of the participants' attitudes that included integrity, altruism, perceived barriers, and theory of planned behavior (TPB). One hundred twenty participants [students: n = 73, practitioners (PP): n = 47), with a mean-age of 27.7 ± 5.3 years, completed the survey (response rate: 100%). Fourth-year students scored better than the PP in integrity (p = .019). For altruism, the students scored better than PPs (vs. fourth-year: p = .009, vs. fifth-year: p = .031). There were no differences between the participant groups for the overall assessments of the TPB (p = .213), VI (p = .863), and HI (p = .261). CONCLUSION: Dental practitioners and students revealed a positive attitude, with few barriers, towards treating individuals with disabilities/sensory impairments and considered the training in the field of special care dentistry as a necessary part of the dental education. Furthermore, a demand for an increase in the hands-on practical experience in treating individuals with disabilities/sensory impairments during the undergraduate study curriculum was identified.

DENTAL PATIENT-REPORTED OUTCOMES IN GERIATRIC DENTISTRY : A call for clinical translation.

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.

Exploring the acceptance of geriatric dentistry programming for undergraduate dental students through stakeholder interviews.

PURPOSE/OBJECTIVES: Older adults frequently report unmet oral healthcare needs. Current research suggests a lack of provider willingness to perform geriatric dental care plays a role in limiting older adults' access to dental services. To better understand the acceptance of geriatric dentistry programming in Ontario, and to explore considerations for successful implementation, we completed consultations with dental students and dental education stakeholders. Findings from a scoping review we conducted previously (Alicia C. Brandt and Cecilia S. Dong) were used to guide this research. METHODS: Consultations involved a questionnaire and semi-structured individual interviews. Descriptive and parametric statistics such as Pearson's bivariate correlation and One-way analysis of variance were completed on questionnaire data using SPSS V.28. Interview data were transcribed verbatim, and the content was analyzed using emergent coding and thematic analysis in NVivo. Student and faculty data were analyzed separately and then consolidated. RESULTS: Ten students and 12 dental faculty members completed the questionnaire of which ten students and nine faculty members also participated in interviews. Themes were organized into barriers and facilitators, with a subsection on interprofessional collaboration. Barriers included: 1. Student anxiety and skill level; 2. Constraints of the learning environment; 3. Patient factors; and 4. Knowledge gaps. Facilitators included: 1. Learning environment and culture; 2. Volume of exposure; 3. Soft skills; and 4. Desired interventions. CONCLUSIONS: Both students and faculty stakeholders demonstrated acceptance of geriatric dentistry programming at the undergraduate dentistry level that supports improved access to care for this population. Pilot programs integrating different intervention elements which were viewed as most promising would be beneficial.

Reliability between the two-colour chewing gum and the gummy-jelly tests used for the assessment of masticatory performance.

OBJECTIVE: This study aimed to evaluate the reliability of two methods used to assess masticatory performance and attempt to correlate them to achieve interchangeability between the methods. METHODS: Twelve healthy dentate volunteers (men = 6, women = 6; mean age = 28.3 ± 4.1) with no known dental or medical pathologies were requested to participate in this study. Each participant completed three masticatory performance assessments, including two two-colour mixing-ability tests using chewing-gums (CG: gum#1 and gum#2) and the gummy-jelly (GJ) test. For each method, participants created five samples each (total = 15 measurements per participant, gum#1 = 5, gum#2 = 5, GJ = 5). For the gum#1 and gum#2 methods, the predetermined chewing cycles were fixed at 10, 15, 20, 25 and 30 cycles, and for the GJ method, the time duration was fixed at 10, 15, 20, 25 and 30 s. The parameter measures were submitted to Z-score transformation, and Bland-Altman plots were generated to graphically compare the differences between two techniques against their means. Additionally, mountain plot was used to assess the cumulative distribution of measurement error between the methods. RESULTS: A total of 180 measurements were recorded. There were significant correlations between the number of chewing cycles/chewing time and masticatory performance using the gum#1 (r = -.753; p < .001), gum#2 (r = -.838; p < .001) and GJ (r = .730). When all tests were considered together for each method, significant correlations were found (p < .001). A descriptive range of mean values aiming to produce reference value ranges for predictive purposes was achieved considering the interchangeably among the methods [CG = GJ (VoH-mg = dL): 10 cycle = 10 s: 0.329 = 110; 15 cycles = 15 s: 0.177 = 164; 20 cycles = 20 s: 0.130 = 205; 25 cycles = 25 s: 0.086 = 200; 30 cycles = 30 s: 0.077 = 267]. CONCLUSION: The strong correlations and high consistency between the two masticatory performance methods found in this study conclude that the two assessment methods are reliable and interchangeable. Further evaluations are warranted to arrive at a conversion formula for translation of the results between the two methods.

Effect of various surface treatments on relining bond strength of CAD-CAM denture base materials.

PURPOSE: The aim of this study was to analyze the impact of various surface treatments and production methods on the shear bond strength (SBS) between reline material and denture base resins. MATERIALS AND METHODS: One-hundred-twenty specimens were produced using conventional heat-polymerization, subtractive, and additive techniques. Each group consisted of 40 specimens. The specimens were divided into four subgroups, each with 10 samples, for surface treatments. These subgroups were: (1) Control-only monomer application, (2) 50 µm airborne-particle abrasion, (3) 110 µm airborne-particle abrasion, and (4) Roughening with tungsten carbide bur. Representative specimens from each subgroup were examined under SEM. Then, auto-polymerized resin was condensed in the center of the specimens. Specimens were subjected to thermal aging (5000 cycles at 5-55°C). The SBS test was conducted and failure loads were recorded. The data were evaluated by two-way ANOVA and Tukey pairwise multiple comparisons method (p < 0.05). RESULTS: The additively produced group showed significantly lower SBS than conventional and subtractive groups (p < 0.001), with no significant differences between the subtractive and conventional groups. Specimens that underwent monomer application only showed the lowest SBS among surface treatments, while 50 µm airborne-particle abrasion showed the highest SBS. Based on the partial eta-squared analysis results, the surface treatment mainly impacted SBS. CONCLUSIONS: Among the surface treatment methods, treating denture bases with 50 µm airborne-particle abrasion is more effective for maintaining adhesion, especially in the additive technique.

AI's Role in Improving Social Connection and Oral Health for Older Adults: A Synergistic Approach.

KNOWLEDGE TRANSFER STATEMENT: This study explored how artificial intelligence (AI) can revolutionize geriatric care by improving oral health and alleviating social disconnection among isolated older adults. The findings can guide clinicians in integrating AI tools into practices, assist policymakers in developing AI-inclusive health policies, and inform patients about the potential benefits of AI in enhancing their health outcomes and social connection.

Clinical parameters that affect performance and patient satisfaction of root-retained overdentures: A systematic review of randomised controlled clinical trials.

OBJECTIVE: To evaluate clinical parameters that affect the performance of root-supported overdentures (ROD) and to identify the possible factors that may affect it. BACKGROUND: ROD still serve as an alternative and successful treatment plan nowadays for partially edentulous patients. Nonetheless, there is not yet conclusive evidence about their clinical evaluation. MATERIALS AND METHODS: A search strategy was developed following a PIO (Population, Intervention, Outcome) framework including an electronic search in the following databases: PubMed, Cochrane Library and Scopus. The systematic search included only randomised controlled clinical trials (RCTs), published until January 2023 in English language and was performed by two independent reviewers. Quality assessment of the included studies was conducted according to the Cochrane Risk of Bias tool. RESULTS: The final selection of studies included 11 RCTs. Clinically relevant variables derived from this search were: Complications, with caries being the most frequently reported, periodontal aspects and bone changes around abutment teeth. Additionally, methods and clinical suggestions for the maintenance of these restorations and patient-related outcomes were assessed. According to the risk of bias assessment, nine studies were considered of high risk, whereas only 2 of low risk. A meta-analysis was not feasible. CONCLUSION: Within the limitations of this systematic review, ROD remain a viable treatment plan, offering better denture stability and bone preservation around abutment teeth and high patient satisfaction. Thorough oral hygiene and regular follow-ups are of utmost importance. Further well-designed RCTs are necessary for firmer conclusions.

Exploring the knowledge, attitudes, and performance of dentists in providing care to elderly patients.

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. TRIAL REGISTRATION: Ethics code IR.KMU.REC.1401.007.

Singapore dentists' attitudes toward dental care provision for older adults with disabilities.

OBJECTIVES: This study aimed to assess dentists' attitudes toward providing dental care for older adults with disabilities in Singapore and the factors influencing their willingness to provide care. BACKGROUND: Dentists face a rapidly ageing patient demographic. Practitioner unwillingness to circumvent the attending challenges of care provision prevents older adults from accessing the dental care necessary for better oral and systemic health. Previous studies have reported on dentists' attitudes toward caring for older adults with disabilities; however, these are mostly limited to dependent older adults and exclude frail, community-dwelling older persons. METHODS: A cross-sectional study was conducted in 2020 using a self-administered questionnaire. Quantitative data analysis was presented in the form of descriptive statistics, followed by bivariate analyses. RESULTS: There were 193 respondents, a response rate of under 9%. Dentists were less willing, confident and involved in the care of older adults with disabilities as the individual's severity of impairments increased. Less than half of respondents were willing to treat individuals with severe disabilities in cooperation (23.3%), swallowing (30.6%), mobility (33.7%) and communication (45.1%). Dentists with training in geriatric dentistry were more willing to provide care. However, younger dentists, general dental practitioners, private practitioners and public sector dentists had specific restraining and driving forces, which further modulated their willingness to provide care. CONCLUSIONS: The current areas of training needs among Singapore dentists are in severe impairments of swallowing, communication, cooperation and mobility. Further geriatric dentistry training may effectively increase dentists' willingness to provide care; however, additional specific targeted interventions are also needed.

Edentulism and Individual Factors of Active Aging Framework in Colombia.

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.

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.

Knowledge and Attitudes of Undergraduate Dental, Allied Oral Health and Nursing Students Towards Patients with Alzheimer's Disease.

Purpose Alzheimer's disease (AD) is an age-related illness that is becoming increasingly more prevalent in the United States. The purpose of this pilot study was to assess dental, allied oral health, and nursing students' perceived knowledge, comfort, and attitudes for individuals with AD.Methods A total of 851 students from a university dental and nursing school were invited to participate in this cross-sectional study. A 48-item survey comprising of demographic questions, the Alzheimer's Disease Knowledge Scale (ADKS) and the Dementia Attitudes Scale (DAS) was disseminated via an electronic survey platform. Responses were summarized as means and standard deviations or counts and rates. Comparisons of survey responses by program type and exposure to AD, age group, and prior degree were performed using the chi-square test for association and analysis of variance.Results The response rate was 33.2%. Nursing students demonstrated the highest level of knowledge on AD with mean score of 25.26 (SD 2.87), followed by dental (M=23.4, SD 3.26) and allied oral health students (M=22.10, SD 2.98). Overall, students demonstrated perceived comfort in treating patients with AD and related dementias with mean scores in the "slightly agree" range. Nursing students demonstrated the highest level of perceived comfort (M=5.61, SD 0.71).Conclusions Nursing students demonstrated higher knowledge and more positive attitudes toward AD than dental and allied oral health students. There is a need for improved educational training and an expanded didactic curriculum to enhance knowledge for dental and allied oral health students. This pilot study provides a blueprint for replication on a national level.

New measure of functional tooth loss for successful Oral ageing: a cross-sectional study.

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.

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 ß = -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 [ß = 1.01 (95%CI, 0.41 -1.62), ß = 1.50 (95%CI, 0.71-2.22)] and attitude [ß = 0.70 (95%CI, 0.06-1.40), ß = 0.73 (95%, 0.13-1.61)] while decreased the perceived barriers [ß = -1.10 (95%CI, -1.91 - -0.32)] respectively. On the other hand, years of experience increased perceived knowledge only after 5-10 years [ß = 1.02 (95%CI, 0.04-2.10)] and after more than 10 years [ß = 1.30 (95%CI, 0.21-2.70)]. Governmental work only increased perceived barriers [ß = 1.33 (95%CI, 0.10-2.54)], while living in the middle and west delta decreased perceived barriers [ß = -0.91 (95%CI, -2.12 - -0.01 and ß = -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.
