Abstract

The aim of this study is to clarify the effect of the change of oral sensory input on brain function and to confirm whether it can be detected electroencephalographically. Eight healthy dentate dental students were selected as subjects, and asked to wear the experimental occlusal interference on the right second molar for 1 week. Simultaneous recordings were made with electromyograms (EMG) and electroencephalogram (EEG) before and after maximum clenching. Evaluation by visual analogue scale (VAS) questionnaires was also done. Twelve‐session experiments were carried out over a period of 12 days. Daily changes of EMG activity of masticatory muscle, six comfort parameters (VAS), and EEG caused by premature contact were analysed statistically applying repeated measured anova and Tukey–Kramer analysis. The discomfort which was described by VAS did not disappear during the interference period. Just after applying the interference, EMG activity during clenching was decreased significantly (P < 0·01) compared with control. Significant change in EEGs between before and after clenching were observed, that is, the percentage power fraction of β wave (%β) tends to increase. On the contrary, %α in EEGs after clenching decreased significantly (P < 0·01) compared with before clenching during the interference period, as verified by VAS evaluation. In conclusion, it is suggested that the decrease of %α in EEGs after clenching may be caused by premature contact influence on the masticatory system, reflected in the presence of discomfort during occlusion, and somatosensor information from the occlusal sensation might be recognized in the higher centre of the brain, and the possibility of detecting change might be indicated electroencephalographically.
