The Prosthetic Application of the Clinical Electrocephalograph(SYNAFIT 2100). Part 1. The Way of the Experiment.

There are many kinds of stress in dental treatment such as pain or discomfort of denture. Since it is too difficult to judge the stress objectively, it was attempted to judge them with the Clinical Electrocephalograph (SYNAFIT 2100). Using palatal plates, some changes in the EEG rate and the EEG distribution were observed. These results suggested application of the EEG to indicate the mental stress due to dental treatment.
