Challenges in oral health research for older adults

Education, Tooth Loss, and Dental Visits: Evidence from Schooling Reforms

Numerous studies have shown that education correlates with tooth loss and dental services use, but whether expanding educational opportunities would reduce tooth loss and improve dental attendance remains unclear given that prior studies lacked a study design to assess causality. We leveraged a policy reform, raising the school leaving age, as an instrumental variable (IV) to estimate the effect of education on edentulism and dental visits in the United States using the repeated cross-sectional data from the Behavioral Risk Factor Surveillance System (BRFSS; N = 463,878). We additionally examined the effect of education on dental visits using longitudinal data from the Survey of Health, Aging and Retirement in Europe (SHARE; N = 69,929). Applying IV probit models, we found 1 extra year of schooling reduced edentulism likelihood by 2.9 percentage points (95% confidence interval [CI]: -0.041; -0.017) and increased dental visit likelihood by 1.2 percentage points (95% CI: 0.01; 0.024) in the United States, with similar effects on dental visits in Europe. Estimates were robust to different model specifications and plausible amounts of imperfect exogeneity. Negative control analysis supported the validity of our findings. This study provides consistent evidence that extended schooling reduces edentulism risk and increases regular dental attendance.

Oral Melanoma in Older Adults: Epidemiology, Molecular Landscape, and Treatment Strategies

Oral melanoma is an aggressive neoplasm arising from melanocytes in the mucosal epithelium, accounting for 0.2%-0.8% of all melanomas. Unlike cutaneous melanoma, it is not associated with UV exposure, and its pathogenesis involves complex genetic and molecular alterations. This neoplasm predominantly affects older adults (≥ 60 years). Clinically, lesions often present as macular or nodular with an exophytic growth pattern, sometimes ulcerated, and exhibit varied pigmentation. Diagnosis is further complicated by non-pigmented (amelanotic) variants that can resemble other oral pigmentations. Wide surgical excision remains the mainstay treatment, often combined with chemotherapy; however, recurrence and distant metastasis remain high. While immunotherapy has shown promise in other melanoma subtypes, its efficacy in oral melanoma remains uncertain. Treatment in older adults is particularly challenging due to comorbidities and treatment-related morbidity. This review summarizes the epidemiology, clinical features, and current treatment strategies for oral melanoma in older adults. Key advances in the molecular mechanisms underlying this neoplasm are also outlined. As a strategic approach, integrating oral melanoma screening into routine geriatric dental care, supported by diagnostic algorithms, may improve early detection, prognosis, and survival outcomes in this vulnerable population.

Responsible artificial intelligence for addressing equity in oral healthcare

Oral diseases pose a significant burden on global healthcare. While many oral conditions are preventable and manageable through regular dental office visits, a substantial portion of the population faces obstacles in accessing essential and affordable quality oral healthcare. In this mini review, we describe the issue of inequity and bias in oral healthcare and discuss various strategies to address these challenges, with an emphasis on the application of artificial intelligence (AI). Recent advances in AI technologies have led to significant performance improvements in oral healthcare. AI also holds tremendous potential for advancing equity in oral healthcare, yet its application must be approached with caution to prevent the exacerbation of inequities. The "black box" approaches of some advanced AI models raise uncertainty about their operations and decision-making processes. To this end, we discuss the use of interpretable and explainable AI techniques in enhancing transparency and trustworthiness. Those techniques, aimed at augmenting rather than replacing oral health practitioners' judgment and skills, have the potential to achieve personalized dental and oral care that is unbiased, equitable, and transparent. Overall, achieving equity in oral healthcare through the responsible use of AI requires collective efforts from all stakeholders involved in the design, implementation, regulation, and utilization of AI systems. We use the United States as an example due to its uniquely diverse population, making it an excellent model for our discussion. However, the general and responsible AI strategies suggested in this article can be applied to address equity in oral healthcare on a global level.

Assessing oral health-related quality of life among older people in home-based care - survey results of the InSEMaP study in Germany

BACKGROUND

Older people receiving home-based care (HBC) often face barriers to access preventive oral health care (OHC) and dental treatments. Leading to deterioration of their oral healthcare. It is further deteriorated by factors such as increasing burden of systemic diseases, medicinal side effects, limited mobility, financial constraints and lack of professional OHC at home. Older people also struggle to maintain necessary daily oral hygiene, leading to malnutrition, weight loss, and a risk of a further health degradation. This cross-sectional survey aimed to investigate the oral health-related quality of life (OHRQoL) and their associated factors in HBC recipients.

METHODS

5,280 older people (≥ 60 years) living in Hamburg, who were in need of care and insured with statutory health insurance DAK-Gesundheit received the questionnaire, which included the German version of the Oral Health Impact Profile (OHIP G-14) and, the EQ-5D health-related quality of life (HRQoL) measure as well as further questions regarding the extent of informal social support, subjective oral health status, oral health behaviour, subjective cognitive status, and socio-demographic variables.

RESULTS

The participants (n = 1,622) had a median age of 83.2 years, with 72.0% of the sample being female. Nearly two thirds of the sample reported that their independence or abilities were significantly impaired (care level 2). Regarding oral health impacts, 40.0% of the participants reported experiencing at least one of the fourteen possible prevalent impacts of the OHIP-G14 fairly often or very often. A multivariate regression model on the severity of oral health impacts revealed, that a better HRQoL, a positive perception of one's own dental status, fewer visits to dental practices, and no need for support in OHC were associated with better OHRQoL. Conversely, respondents with a negative perception of their oral health status, more frequent visits to a dental practice, a need for support in OHC, and subjective memory impairment showed poorer OHRQoL.

CONCLUSIONS

The results highlight the risk for poor oral health among older people in HBC. We conclude that there is an urgent need to prioritise oral health, especially as poor oral health can further compromise the systemic wellbeing of these already care dependent population.

Challenges to conducting research on oral health with older adults living in long-term care facilities

BACKGROUND

The challenges to conducting oral health studies involving older people in long-term care facilities (LTCFs) must be debated.

OBJECTIVE

This study aimed to investigate researchers' perceptions and experiences while conducting an epidemiological survey on oral health among older individuals residing in LTCFs.

METHODS

A qualitative study was conducted involving six researchers who utilized field diaries to record their impressions during data collection through interviews (older individuals (or their proxies), caregivers, and LTCF coordinators) and oral examinations of the older people participants. Additionally, researchers responded to open-ended questions about their experiences. The collected material was subjected to content analysis by two researchers.

RESULTS

The themes that emerged from the analysis were institutional context, aspects affecting the operationalization of the study, and data collection oriented by the clinical-functional profile of the older people. According to the researchers' perceptions, LTCF coordinators demonstrated concern for the study's benefits for older adults and the preservation of institutional routines during the research process. Caregivers emerged as vital sources of information, guiding researchers in navigating the challenges posed by the physical and mental complexities of the older people participants, necessitating empathy, sensitivity, and attentive listening from the researchers. The organization of materials and a streamlined data collection process proved essential for optimizing time efficiency and reducing stress for participants and researchers.

CONCLUSION

The researchers recognized the important role played by LTCF coordinators and formal caregivers, underscoring the significance of empathetic methodologies and streamlined data collection processes in mitigating the challenges inherent to research conducted within LTCFs.
