| Research Abstract |
Electroencephalography showed tha making the ecperimental palatal plate thinner became oral sense more sentitive and the rate ofαwave higher, and there was no significant difference between with and without dentures for the subjects adapting to them.
It showed that taste stimulation influenced cerebral circulation using Infraed spectroscopy and gum with and without taste.
Moreover, there is no significant difference of lip-closing force in between age groups for female, and the lip-closing force in the elderly group is higher than that in the young and middle aged groups for male. The lip-closing force without denture is higher than with denture.
