Analysis of feeding function and jaw stability in bedridden elderly.

Area of Science:

• Gerontology
• Oral Health
• Swallowing Disorders

Background:

• Dysphagia is a common and serious condition in bedridden elderly individuals.
• Impaired feeding function, including swallowing difficulties, significantly impacts patient health and quality of life.
• Jaw stability is a potential, yet understudied, factor influencing oral feeding in this population.

Purpose of the Study:

• To investigate the association between jaw stability and feeding function in elderly patients with dysphagia.
• To determine if posterior occlusal support influences swallowing ability.
• To identify objective measures of feeding performance related to mandibular stability.

Main Methods:

• A cohort of 53 bedridden elderly patients with dysphagia was assessed.
• Methods included questionnaires, oral examinations for jaw stability, and functional feeding tests.
• Key assessments were the Repetitive Saliva Swallowing Test (RSST) and a water swallowing test.

Main Results:

• 34% of patients exhibited posterior occlusal support, defining mandibular stability (ST) versus no mandibular stability (NST).
• The NST group showed significantly poorer performance in the RSST (83.3% unable to swallow >3 times) compared to the ST group (40.0%).
• In the water swallowing test, 91.4% of the NST group failed to swallow 15 mL in a single swallow, versus 40.0% of the ST group.

Conclusions:

• Jaw stabilization, achieved through posterior occlusion (natural teeth or prosthetics), is vital for effective feeding function in dysphagic elderly patients.
• Maintaining occlusal support appears to be a critical factor in improving swallowing safety and efficiency.
• These findings highlight the importance of dental assessment and intervention for managing dysphagia in the elderly.
