Special Issue Information

Dear Colleagues,

The global ageing population is growing both in number and proportion, with older adults projected to constitute one in six people by 2050. Ageing is associated with various physiological changes, chronic medical conditions, polypharmacy, and cognitive and physical decline, all of which elevate the risk of oral diseases among older adults. Although oral diseases are largely preventable, many oral health problems remain untreated in older adults, often due to physical and financial barriers to accessing dental care. Oral health plays a vital role in essential functions such as eating, breathing and speaking. Moreover, oral health is closely linked to systemic health, nutritional status, mental well-being and cognitive function in older populations. Therefore, improving oral health in older adults is crucial for promoting healthy ageing and enhancing overall quality of life.

This Special Issue aims to highlight the importance of oral health in the context of healthy ageing and to present the latest evidence-based approach for improving oral health among older adults. We seek to publish high-quality research covering a wide range of topics, including but not limited to oral health education, oral function promotion, and the prevention, early detection and management of oral diseases in the older population. We welcome submissions of original articles such as laboratory, qualitative, and clinical studies, critical reviews, and short communications that offer valuable insights into enhancing oral health in older adults.

Objectives: This study investigated the impact of age on the diagnostic accuracy and patient acceptance of two chewing efficiency tests: the digital Mini Dental Assessment (MDA) using carrots and the CHEW test by Slavicek using fruit gum, applied in both clinical and nursing home settings. Methods: Seventy participants aged 18 to 99 years from dental clinics and nursing homes were included. All participants received a standardized dental examination (reference standard) and performed the MDA and CHEW tests. Sensitivity, specificity, and AUC values were calculated using ROC analysis. Participants rated both tests in terms of taste, consistency, comprehensibility, required time, and subjective chewing sensation. Acceptance was analyzed across age groups and prosthesis types. Results: Both chewing efficiency tests showed good agreement with the clinical reference standard. The AUC was 0.72 for the MDA and 0.78 for the CHEW test (p = 0.192). Sensitivity was higher for the CHEW test (100%) compared to the MDA (83.3%), while the MDA demonstrated slightly higher specificity (59.6% vs. 55.8%). Age significantly influenced both diagnostic outcomes and test acceptance (p < 0.05). Younger participants (<70 years) were more often correctly classified as healthy and tended to prefer the MDA, whereas older participants (≥70 years) preferred the CHEW test, primarily due to taste. Misclassifications occurred most frequently among participants with complete dentures. Conclusions: Both the digital MDA and the CHEW chewing test demonstrated good diagnostic performance in identifying treatment need. Acceptance varied significantly with age, suggesting that test selection may be optimized based on patient characteristics. These simple and rapid assessments may support early detection of dental treatment needs in clinical and nursing home settings. Full article

Oral health in older adults is a critical component of overall well-being requiring integrated, interdisciplinary approaches to address its complex interplay of medical, functional, and psychosocial challenges. The aim of this is to examine strategies to enhance interdisciplinary collaboration among dental professionals, physicians, nurses, nutritionists, and caregivers to improve oral health outcomes in aging populations. Older adults commonly face dental problems such as periodontal disease which can be exacerbated by polypharmacy, systemic diseases, and barriers to accessing care. These multifaceted needs necessitate coordinated efforts across dentistry, geriatric medicine, nursing, and social support systems. Strategies of effective interdisciplinary care include: (1) Medical-dental integration, enabling physicians to screen for oral health issues during routine assessments; (2) Nursing and caregiver engagement in daily oral hygiene support and early problem identification; (3) Nutritional interventions tailored to address chewing difficulties and prevent malnutrition; (4) Social support systems to improve access to affordable care; and (5) Technology-driven solutions such as tele-dentistry to enhance communication, early detection, and care coordination. Despite these opportunities, systemic barriers persist, including fragmented healthcare systems, financial constraints, workforce shortages, cultural biases, and technological gaps. Progress requires commitment from policymakers, healthcare institutions, and health care professionals to prioritize geriatric oral health as a public health imperative. In conclusion, interdisciplinary collaboration enhances older adults’ oral-systemic health via cross-sector policies and healthcare workforce education. Implementing these strategies can mitigate oral health disparities, reduce the burden of chronic diseases, and improve quality of life for aging populations through holistic, patient-centered care.
