Brain wave synchronizers: Part 2--A pilot EEG study and a clinical observational study

In the first brain wave synchronizer study by our group at Temple University (the readers are referred to part 1, which appeared in the January 1994 issue of The Compendium), patients undergoing endodontic therapy were divided into three groups: the Relaxodont unit, the Relaxodont unit with a relaxation tape, and a control group. The anxiety levels of the groups were compared using galvanic skin resistance, pulse rate, subjective response, and physical reactions. The results showed that the two Relaxodont groups did significantly better than the control group. In part 2, a pilot brain wave synchronizer electroencephalogram study is presented. The results of a clinical observational study on endodontic patients by our group at Temple University using simple chairside means to assess anxiety is also presented.
