Objective: To describe the oral health of older people by region and family status using data from the National Health and Nutrition Survey.

Background: As the ageing of Korean society intensifies, health inequalities based on region and family status are also deepening.

Methods: Data from the 8th National Health and Nutrition Survey (2020-2021) conducted by the Korea Centers for Disease Control and Prevention were used, and a total of 3437 older people aged 65 or older were selected as study participants. Chewing discomfort and oral health behaviours were assessed by region and family status using multivariable logistic regression analysis with the complex sample survey design.

Results: We found an association between living alone and greater chewing discomfort. Residing in rural areas was also associated with a higher prevalence of this. In urban areas, chewing discomfort was 1.27 times higher among older people living alone than in those not living alone, while in rural areas, the discomfort was 1.52 times higher among the older people who lived alone.

Conclusions: Region and family status were associated with greater chewing discomfort in older people. In Korean society, where the number of single-person older people households is increasing, along with the ageing population, attention to resolving the disparities in oral health in older people is needed.

Background/objective: Tooth loss is common among older adults and can affect dietary intake and weight status. This study investigated associations between dentition status and body mass index (BMI) in older adults.

Materials and methods: This was a cross-sectional study of data from a convenience sample of older adults (65-89 years) treated at an urban U.S. dental school clinic. Clinical and demographic data were obtained from electronic health records. Dentition status was determined based on data from odontograms. Multinomial logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of having a non-normal weight status for each measure of dentition status, after adjusting for covariates.

Results: Patients (n = 1765) were 54.1% female, 51.5% White, 41.6% African American and 22.5% Hispanic/Latino. The median (interquartile range [IQR]) age was 71 (67.0-75.0) years; the mean (±SD) BMI was 28.5 (±5.7) kg/m²; 72.5% were overweight or obese. The median (IQR) number of remaining teeth was 20.0 (13.0-24.0); the median numbers of anterior and posterior occluding pairs of teeth were 5.0 (2.0-6.0) and 2.0 (0.0-5.0), respectively; and 44.9% had a functional dentition (≥21 teeth). Having a higher number of remaining teeth and more posterior occluding pairs were associated with lower odds of obesity (OR = 0.980, 95% CI = 0.964, 0.997, p = .022 and OR = 0.931, 95% CI = 0.885, 0.980, p = .006, respectively). Lack of a functional dentition was associated with higher odds of obesity (OR = 1.400, 95% CI = 1.078, 1.818, p = .012), after controlling for covariates.

Conclusion: Older adults with tooth loss - especially loss of posterior occlusion and lack of a functional dentition - were more likely to be obese than of normal weight.

Objective: This study aimed to explore older patients' oral health status, their opinions about oral health care and their experiences with oral health care while in hospital.

Background: Improving older adults' oral health is considered an urgent priority at both the national and international levels, especially for hospitalised older patients who have been found to have poor oral health. However, a one-size-fits-all standardised approach to oral care delivery may not be the answer.

Materials and methods: This study was an embedded, multiple-case study, integrating qualitative and quantitative data. Seven patients were recruited from a geriatric ward of an acute hospital in Australia and participated in semi-structured interviews and oral health assessments using the Oral Health Assessment Tool (OHAT) in June-July 2022. Data were analysed descriptively and presented in case summaries.

Results: OHAT assessments identified oral health problems in all patients, but not all patients self-reported problems with their mouths. Each patient valued oral health care, but the reasons given varied. Patients had established, individualised oral health care routines, which they brought to hospital.

Conclusion: Clinical observations of patient's oral health status might not match the patient's own judgement of their oral health and, if not explicitly addressed, may mask the need for oral health and hygiene intervention. Assessment and care planning needs to incorporate patients' own perceptions of their oral health and existing oral health care routines. Oral health histories may provide a means of facilitating this person-centred oral health care for older patients in hospital.

Objectives: To assess ARC residents' and staff perceptions of the benefits of, and comfort with, teledentistry use in ARC facilities in the Otago region of NZ, and identify end-user-level factors associated with its use.

Background: Difficulty in accessing oral healthcare services is a key barrier to aged residential care (ARC) residents' oral health and well-being. Teledentistry offers a possible solution, yet studies on its acceptability in ARCs are sparse, especially in New Zealand (NZ). This study assessed ARC residents' and staff perceptions of the benefits of, and comfort with, teledentistry use in ARC facilities in the Otago region of NZ and identified end-user-level factors associated with its use.

Materials and methods: Rest home-level residents and care staff in ARC facilities in the Otago region of NZ were surveyed to assess their awareness of teledentistry, perceptions of benefit and comfort using teledentistry, and end-user-level factors associated with the feasibility of using it in ARCs.

Results: One hundred residents and 77 care staff from 14 facilities participated. Three-quarters of resident participants thought that teledentistry was beneficial. Three in five resident participants were comfortable receiving remote dental consultations and care advice through teledentistry. Acceptability, as measured by perceived benefits and comfort, was lower among older participants. Staff participants were receptive to teledentistry use for residents and were comfortable facilitating remote dental consultations and care through teledentistry. No staff participants disagreed with the potential benefits of teledentistry for ARC residents.

Conclusion: Teledentistry would likely be acceptable to residents and staff in ARC facilities in NZ, contributing to residents' improved access to oral health care and improved oral health and well-being.

Background: Root caries affect the oral health and quality of life of older adults. This study examines the breadth of global research on this topic, aiming to clarify its expansive scope and to shed light on pertinent trends for new researchers in the field.

Objective: To identify key advances in root caries research as highlighted in high-quality articles from the Social Science Citation Index (SSCI) as well as to explore emerging trends and perspectives.

Materials and methods: Using the Web of Science (WoS) database, we conducted a comprehensive review of articles related to root caries in older adults. Our focus was on finding high-quality SSCI articles, identifying major contributors, journals and research trends and exploring areas such as dentistry, oral surgery and medicine for potential future research.

Results: Our analysis included 192 articles, each of which was subjected to bibliometric and VOS viewer evaluations. The results revealed a concentration of studies in dentistry, oral surgery and medicine, with gaps identified in areas like anthropology, biochemistry, molecular biology and chemistry. A notable deficiency was found in root caries management.

Conclusion: We discuss research gaps and propose future directions based on our findings, emphasising interdisciplinary research approaches.

Background and objectives: There is limited evidence on knowledge of related health among healthcare personnel who care for older adults. The objective of this study was to investigate the knowledge and experience of oral health care among family members and medical staff responsible for older adults with varying degrees of cognitive impairment and Alzheimer's disease.

Materials and methods: This qualitative study explored the experiences and knowledge of 30 family members and medical staff through in-depth, semi-structured interviews. The interviews were recorded using both audio and video formats: digital platforms were used for immediate family members, while formal caregivers were interviewed in person. Researchers transcribed and analysed the recordings, categorising the answers to identify emerging topics until reaching saturation.

Results: The core emerging themes among the direct family members were: (1) Lack of knowledge about oral health; (2) Oral hygiene role for the patients; (3) Consequences of a poor oral care; and (4) Recommendations for a better oral health care. For the formal caregivers the emerging themes were: (1) Lack of knowledge and experiences about oral health; (2) Deficient oral hygiene of residents; (3) Impact on quality of life; and (4) Suggestions for improving oral health.

Conclusion: Despite recognising the significance of oral health, direct family members and formal caregivers of older adults with cognitive impairment or dementia still need additional tools to effectively carry out necessary hygiene techniques and care.

Objectives: The study compares three minimally invasive approaches for the retention of implant supported mandibular complete dentures, particularly focusing on patient satisfaction.

Background: The McGill Consensus Statement recommends restoration of the edentulous mandible with an overdenture retained on two implants. Alternatively, less invasive treatment concepts with shorter treatment times have been developed for critical cases.

Material and methods: Thirty-nine patients (with a total of 78 implants) with advanced mandibular bone atrophy were randomly assigned to three groups: "single standard implant-retained overdentures" (SSO) and "mini-implant-retained overdentures" (MO), which was further subdivided into "two mini-implant-retained overdentures" (TMO) and "four mini-implant-retained overdentures" (FMO). The technical and biological parameters and oral health-related quality of life were evaluated over a 10-year period. Data were analysed for group comparisons and longitudinal trend analysis.

Results: Sixteen patients (42%) dropped out during the study period. At the time of follow-up, 98.4% of the implants were in situ. The first need for technical intervention occurred after 3.8 ± 1.1, 4.2 ± 0.9, and 4.6 ± 1.3 years in the TMO, SSO, and FMO groups, respectively. Attachment exchange (39%) was the most frequently performed intervention in all groups. Healthy peri-implant and mucosal conditions were observed in 74% and 40% of patients after 1 and 10 years, respectively. The OHIP-G14 score was 22.6 before implantation, 7.6 at 1 year (effect size [ES]: 1.1), and 5.4 at 10 years (ES: 2.3).

Conclusion: Irrespective of the minimal concept selected, complete mandibular dentures retained on implants improved the subjective perception of the quality of life. Application of these alternative minimal concepts may be practical in clinical practice.

Objective: This study aims to map the existing literature on natural products used as disinfection substances for conventional polymethyl methacrylate (PMMA) and computer-aided design and manufacturing (CAD-CAM) dentures.

Background: Denture wearers are at high risk for denture stomatitis. Natural products have attracted the interest of the scientific community as an alternative to synthetic ones.

Materials and methods: The guiding question "Which natural products have been applied to disinfect complete dentures in conventional PMMA or CAD-CAM PMMA resin?" Searches were conducted in the PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases, and manual searches were performed in reference journals in the area with studies published until December 2023, without language or date restrictions.

Results: A total of 4272 articles were identified, and 46 studies were included after applying the eligibility criteria. Thirty-nine natural products were evaluated. Of the included studies, 43 presented positive findings and three obtained negative findings on the effectiveness of natural products in inhibiting or killing Candida albicans.

Conclusion: Natural products, predominantly sourced from the Plantae kingdom, have demonstrated efficacy in reducing Candida albicans on the surface of conventional PMMA. However, the evidence primarily stems from in vitro studies, underscoring the necessity for additional clinical research to validate their applicability under real microbiological conditions in prosthesis users.

Objective: To evaluate the validity of the newly developed Oral Hygiene Ability Instrument (OHAI), created to assess the cause of any inability of older adults to perform oral hygiene, and to revise the instrument based on the results.

Background: Good oral hygiene is among the most important prophylactic measures for oral health. This applies especially to older adults, among whom risk factors and physical and cognitive barriers are more common and can hamper oral hygiene.

Methods: The OHAI contains (I) an interview, (II) clinical examination, (III) observation of oral hygiene activities and a summarising part. In the study, 149 older adults in three groups participated: stroke, cognitive disorder and general dental patients. Inclusion criteria were to be ≥65 years old, have at least one tooth and to manage oral hygiene without assistance. For criterion validity, sensitivity and specificity were calculated using eight reference instruments. To determine construct validity, we used known group validity, factor analysis and Rasch analysis.

Results: The criterion and construct validity of the OHAI were found to be acceptable to good. In the stroke group, balance and fine motor skills were assessed to affect oral hygiene most; in the cognitive disorder group, it was balance, coordination, spatial ability and cognitive functions. Analyses revealed that one item had no added value and that some response options were not optimal.

Conclusion: The OHAI proved to be valid for the group it is intended for, with only minor revisions needed, resulting in a 32-item instrument. The OHAI could be a valuable person-centred tool in prophylactic work with older adults with failing oral hygiene.
