For many older adults, the simple act of eating a meal is not merely a matter of appetite, but a complex challenge of mechanics. When removable prosthodontics—better known as dentures—fail or are neglected, the impact ripples far beyond the mouth. It affects the ability to chew nutrient-dense foods, the confidence to engage in social conversations and the overall psychological well-being of the individual.
Despite these clear connections, dental care has historically existed in a silo, separate from the broader medical management of aging. However, a growing movement toward integrating oral health into the World Health Organization’s (WHO) Integrated Care for Older People (ICOPE) framework is beginning to challenge this divide. By analyzing the intersection of these two fields through a scientometric lens—a method of quantifying scientific research trends—experts are highlighting a critical gap: while we understand that oral health matters, we are not yet treating it as a core pillar of geriatric integrated care.
The goal of integrating oral health into ICOPE is to shift the focus from treating a single tooth or a loose denture to maintaining “intrinsic capacity.” In the medical community, this means looking at how a person’s physical and mental capabilities allow them to do what they value. When a senior loses the ability to eat properly due to poor oral health, their nutritional status drops, their energy wanes, and their risk of frailty increases, directly undermining the objectives of integrated care.
The Silo Effect: What Scientometric Analysis Reveals
Scientometrics allows researchers to map the landscape of global medical literature, tracking how often specific terms and concepts overlap in published studies. In the case of integrating oral health into ICOPE, this analysis reveals a stark disparity. While there is a wealth of research on removable prosthodontics and a separate, robust body of work on the WHO ICOPE guidelines, the two rarely meet in the same academic papers.
This “silo effect” suggests that dentists and geriatricians are speaking different languages. Prosthodontists focus on the fit, stability, and function of dental appliances, while integrated care providers focus on locomotion, cognition, and nutrition. The disconnect is dangerous because it leaves the patient to navigate the gap. An older adult may be seen by a primary care physician for weight loss and malnutrition, yet the underlying cause—a poorly fitting set of dentures that makes chewing meat or vegetables impossible—remains unaddressed because the physician is not screened for oral function.
By quantifying this gap, scientometric studies provide a roadmap for where future research and policy must go. They argue that for ICOPE to be truly “integrated,” oral health cannot be an optional add-on; it must be a primary screening tool used to prevent the decline of functional ability.
Connecting the Dots: From Dentures to General Health
To understand why bridging this gap is urgent, one must look at the biological cascade that occurs when oral health fails. As a physician, I often see the end results of this cascade in the clinic: a patient admitted for pneumonia or severe malnutrition, only to discover upon examination that they have severe periodontal disease or missing teeth that prevented them from eating a balanced diet.
The relationship between removable prosthodontics and integrated care can be broken down into three primary domains of impact:
- Nutritional Status: The ability to maintain a diverse diet is dependent on masticatory efficiency. When prosthetics fail, patients often shift toward soft, processed foods that are higher in sugar and lower in essential proteins and vitamins, accelerating muscle loss (sarcopenia) and frailty.
- Psychosocial Well-being: Oral health is tied deeply to dignity. The embarrassment of loose dentures or missing teeth often leads to social isolation, which is a known risk factor for depression and cognitive decline in the elderly.
- Systemic Inflammation: Chronic oral infections and poor hygiene are linked to systemic inflammation, which can exacerbate conditions like cardiovascular disease and diabetes, complicating the management of multiple comorbidities in older adults.
The Integration Gap in Clinical Practice
| Feature | Traditional Siloed Care | Integrated ICOPE Model |
|---|---|---|
| Oral Health Focus | Reactive (treating pain/breakage) | Proactive (maintaining function) |
| Coordination | Patient refers themselves to dentist | Primary care screens for oral capacity |
| Goal of Treatment | Restoring the appliance | Improving overall nutritional intake |
| Outcome Measure | Fit of the denture | Maintenance of intrinsic capacity |
Implementing a Multidisciplinary Approach
Moving from a scientometric observation to a clinical reality requires a change in how healthcare teams are structured. A truly integrated model would see the dental professional as a core member of the geriatric care team, rather than an outside consultant. This involves implementing standardized oral health screenings as part of the initial ICOPE assessment.
For example, when a provider assesses a patient’s nutrition—one of the key domains of the ICOPE framework—the checklist should explicitly include a functional oral assessment. Does the patient have teeth or prosthetics? Are they stable? Can the patient chew a variety of textures? If the answer is no, the referral to a prosthodontist becomes a medical necessity for the prevention of malnutrition, not just a cosmetic preference.
this integration requires a shift in policy and reimbursement. In many healthcare systems, dental care is funded separately from medical care, creating a financial barrier that prevents the remarkably integration that ICOPE advocates. Bridging this gap requires a systemic recognition that a well-fitting denture is a medical device essential for the maintenance of general health in old age.

The next step in this evolution will likely be the formal inclusion of oral health indicators within the updated WHO global monitoring tools for healthy aging. As researchers continue to document the link between masticatory function and longevity, the medical community is expected to move toward a model where the mouth is treated as the gateway to overall systemic health.
