“…However, the present study did not evaluate potential factors, such as type of prosthesis or condition of missing teeth. Moreover, the cause of tooth loss and subsequent denture use, as well as the support style, size, and quality of the dentures might be related to elements of cognitive decline (Cerutti-Kopplin et al, 2015;Yamamoto et al, 2012).…”

Background: Diminished oral motor function is considered to be a factor influencing cognitive decline, but this association has not been clarified. The aim of the present study was to clarify the association between cognitive and oral motor function in older people with either from normal cognitive function or mild cognitive decline. Methods: A cross-sectional study was conducted across 1,118 older people (445 men, 673 women) aged ≥70 years (mean age, 77.0 ± 4.7 years) who lived in a city of Tokyo Metropolis, Japan. Cognitive function was assessed using the Mini-Mental State Examination (MMSE). Older people who had an MMSE score of 23 points or lower were excluded. To investigate the relationship between cognitive and oral motor function, Pearson's correlation, multiple linear regression, and path analysis were performed. Results: Pearson's correlation revealed that, among the oral motor functions assessed, masticatory performance, occlusal force, and tongue pressure were correlated with MMSE score. Multiple linear regression showed that tongue pressure and oral diadochokinesis (ODK) were significantly associated with MMSE score. Path analysis revealed that decreases in tongue pressure and in ODK were directly associated with decreases in MMSE score. Decreases in tongue pressure were also indirectly 2 associated with decreases in MMSE score via decreases in ODK. Conclusions: Among the oral motor functions assessed, tongue pressure and ODK were associated with cognitive function in older people ranging from those with normal cognitive function to those with mild cognitive decline. Diminished tongue pressure and ODK might thus lead to cognitive decline.

“…The association between occlusal force (i.e., masticatory stimulation) and global motion coherence persisted when considering only data from participants with four supporting areas, indicating that the observed relationship was not an artifact due to missing support zones. Chewing and masticatory stimulation have been suggested to enhance mnemonic function in middle-aged adults and the elderly [ 15 , 18 , 20 , 21 ]. To the best of our knowledge, this represents the first study to indicate a facilitatory effect of masticatory stimulation on perceptual ability in developing humans.…”

“…Thus, whether masticatory stimulation also facilitates other important function such as visual perception remains unclear. In addition, the majority of existing studies have focused on the effects of mastication in the elderly [ 18 , 20 , 21 ], with few having paid attention to developing populations, despite accumulating evidence from animal studies that masticatory stimulation influences performance in learning and emotional response during the growth period as early as the early postnatal stage [ 5 ].…”

Occlusal force predicts global motion coherence threshold in adolescent boys

BackgroundBeneficial effects of mastication on cognitive abilities in the elderly have been shown in human studies. However, little is currently known about the effect of masticatory stimulation on cognitive and perceptual ability in younger populations. The purpose of the present study is to investigate the influences of masticatory stimulation on perceptual ability in adolescent boys.MethodsThe present study examined the relationship between occlusal force (i.e., masticatory stimulation) and visual perception ability in adolescent boys. Visual perception ability was quantified by measuring global motion coherence threshold using psychophysical method. As an index of masticatory stimulation, occlusal force was measured by pressure sensitive film. We also measured participants’ athletic ability, e.g. aerobic capacity and grip strength, as potential confounding factor.ResultsThe multiple regression analysis revealed a significant negative correlation between global motion coherence threshold and occlusal force, which persisted after controlling for confounding factors such as age and aerobic capacity.ConclusionsThis finding indicates that masticatory stimulation enhances visual perception in adolescent boys, indicating the possibility that beneficial effects of masticatory stimulation are observed not only in the elderly but in developing population consistently with the findings of the previous animal studies.

“…Humans who have lost teeth and were subsequently given dentures or dental implants that restored dental function also had improved prefrontal cortex activity ( Narita et al, 2009 ; Kimoto et al, 2011 ; Kamiya et al, 2016 ), along with improved cognitive performance ( Cerutti-Kopplin et al, 2015 ; Banu et al, 2016 ; De Cicco et al, 2016 ).…”

The human brain sustains a slow but progressive decline in function as it ages and these changes are particularly profound in cognitive processing. A potential contributor to this deterioration is the gradual decline in the functioning of multiple sensory systems and the effects they have on areas of the brain that mediate cognitive function. In older adults, diminished capacity is typically observed in the visual, auditory, masticatory, olfactory, and motor systems, and these age-related declines are associated with both a decline in cognitive proficiency, and a loss of neurons in regions of the brain. We will review how the loss of hearing, vision, mastication skills, olfactory impairment, and motoric decline accompany cognitive loss, and how improved functioning of these systems may aid in the restoration of the cognitive abilities in older adults. The human brain appears to require a great deal of stimulation to maintain its cognitive efficacy as people age and environmental enrichment may aid in its maintenance and recovery.

Cognitive status of edentate elders wearing complete denture: Does quality of denture matter?

Abstract: The potential beneficial effect of functional dentures on cognitive status via mastication could encourage preventive strategies to decrease substantial risk of morbidity in elders.
