A novel prosthesis presentation test to screen for cognitive and functional decline.

Objectives and background: To validate a novel screening test for cognitive and functional decline in older patients rehabilitated with complete removable dental prostheses (CRDPs). Materials and methods: Edentate old in‐patients rehabilitated with CRDPs were included in this study. Participants were requested to remove their prostheses before their intraoral examinations. The prostheses were then presented in an inverted orientation. Participants had to correct the orientation of the prostheses and insert them in the appropriate jaws. The test was repeated after the intraoral exam. Appropriate statistical models were used (⍺ =.05) to associate the test results with the participants' mini‐mental state examination (MMSE) score, functional independence measure (FIM), age and sex. Results: Among the 86 participants (mean‐age: 85.4 ± 6.4 years; mean MMSE: 19.8 ± 5.5; mean FIM: 77.9 ± 20.8), 21 (24.4%) failed to correctly insert the prosthesis. The prosthesis presentation test (PPT) was associated with the FIM but not the MMSE. Regression models further confirmed an association with age (P =.043), but not sex. Additional analyses revealed the PPT test is associated with the FIM's cognitive sub‐sets of memory, problem solving and social interaction. Conclusion: The PPT is a novel, simple and quick screening tool that can help detect functional difficulties in older people. It can easily be performed during an oral examination. Future studies are needed to determine whether the PPT can be used to detect deficits in executive function, as a complement to the MMSE and also as a first assessment of a patient's ability to manage dentures independently.
