Oral Health Linked to Function and Nutrition in Older Inpatients
A cross-sectional study of 150 older inpatients with disabilities examined how oral health relates to dependence, cognition and nutritional status.

Researchers conducted a cross-sectional study of 150 older inpatients with disabilities recruited from two medical-care institutions between June and December 2025. The study examined oral health alongside functional dependence, cognitive function and nutritional status.
Why it matters
Oral health is assessed alongside functional, cognitive and nutritional measures in this population, where severe functional dependence and malnutrition risk were common. The findings point to oral health as a factor to consider in care for older people with disabilities.
The study reports a mean Decayed, Missing, and Filled Teeth index of 25.17 ± 6.55 and a mean Gingival Index of 1.39 ± 0.73 among 139 participants with natural teeth. Because it is cross-sectional and uses a convenience sample, the associations it reports cannot establish cause and effect or represent the wider population.
The details
Participants underwent oral examinations assessing the DMFT index, Gingival Index and prosthetic status. Functional, cognitive, nutritional and comorbidity measures were collected using the Barthel Index, MMSE, MNA-SF, Charlson Comorbidity Index and a medication count. Eleven edentulous participants were excluded from gingival analyses.

Health Landscape
The study applies the Mini Nutritional Assessment Short Form alongside oral examinations, extending standard nutrition screening to dental status in older inpatients with disabilities. The sample's high rates of functional dependence and cognitive impairment place these oral health findings within the broader challenge of caring for frail, older adults in institutional settings.
For older people with disabilities, poor oral health may go unnoticed alongside malnutrition and cognitive decline. Caregivers may find that routine dental and nutritional checks are worth coordinating in institutional care.
The takeaway
Oral health is one of several factors that may affect nutrition and daily function in older adults, so it deserves attention alongside diet and cognitive care. Routine oral examinations could help identify risks earlier in people receiving long-term care.
