Research Abstract

Occlusal disturbance caused by the extraction of molar teeth or occlusal disharmony accelerate impairment of spatial learning and memory. It is possible that the loss of occlusal support by teeth extraction caused adecline of the spatial memory, and the recovery of occlusal support wearing the experimental denture controlled a decline of the spatial memory. Also, it was suggested that the loss of occlusal support caused a decline of hippocampus pyramidal cell density. Compared to chronic stress, it was not significant difference between control, denture-wearing, and tooth extraction groups. While wearing the experimental denture wasn’t under stress, the chronic stress caused by occlusal disharmony was not accepted.
