Research Abstract

Combining the computerized Kana Pick-out Test as a stressor and fMRI was used for the analysis. This test was examined before and after gum chewing. The result showed the chewing effect for working memory in the brain activity included in the prefrontal cortex. In addition, we investigated the change in brain regional activity for the stress during gum chewing when edentulous subjects switched from mandibular complete dentures (CD) to implant-supported removable overdentures (IOD). This result showed that, within the prefrontal cortex, the neural activity of the frontal pole significantly decreased during gum chewing with IOD when compared to that with CD.
