Abstract
The influence of horizontal changes in the mandibular position on facial and cervical skin surface temperature was investigated, and the results were as fllows:
1. The skin surface temperature generally rose according to horizontal changes in mandibular position, began to decrease gradually before removal of the appliance, and returned almost to the temperature before horizontal changes 30 minutes after removal of the appliance.
2. The EMG activity generally increased according to horizontal changes in mandibular position, began to decrease before removal of the appliance, returned almost to the EMG before horizontal changes 30 minutes after removal of the appliance.
3. The influence of horizontal changes in the mandibular position tended to be greater for the direction L or R than A.
4. There was a close positive correlation between the skin surface temperature and EMG activity at each mandibular position and at each point of measurement.
