Primary Outcome Measures

Name	Time	Method
<p>a. the measure (qualitative/quantitative) of brain activity during teeth<br /><br>clenching<br /><br>b. the measure of brain activity during tmd pain<br /><br><br /><br>Endpoints will be if there is no brain activity at all or the measurements are<br /><br>too weak so that a follow up study will not be indicated anymore; if the<br /><br>measurements of brain activity are strong enough in case of teeth clenching but<br /><br>not in the case of tmd pain, the follow up study will be executed in a modified<br /><br>form. </p><br>
