Abstract.

"The present study was made not only to spectro-analyze the fluctuation of the tapping rhythm in subjects with normal masticatory function and to examine its overlapping with 1/f fluctuation as vital responsibility, but also to observe the influence of an experimental object intervened on the occlusal surface.
As a result, normal subjects showed 1/f spectrum at each subject's proper rhythm, but not 1/f at a metronome-loading rhythm. In case of an object intervened at proper rhythm, the thickness of the object (100, 400μm) was suggested to make change in spectrum".

Keywords: tapping rhythm, power spectrum, 1/f fluctuation, experimental occlusal interference
