- Primary Outcome Measures
Name Time Method Main outcome measure is reduction of pain in the TMJ (0 – 100 mm VAS). <br />Furthermore, a cost-utility analysis will be performed with the QALY (Quality Adjusted Life Years) as primary outcome measure. The VAS pain scale (0-100) will be used as primary outcome measure of the cost-effectiveness analysis. QALYs used in the additionally planned cost-utility analysis will be derived from EQ-5D [EuroQoL group, 1990] (10) results assessed in the context of the current study.
- Secondary Outcome Measures
Name Time Method Additional outcome measures are:<br /><br>- mandibular function (scored as numerical outcome of validated MFIQ and measurements (mm) of the mandibular range of motion)<br /><br>- Oral Health related quality of life (OHIP)<br /><br>- Quality of life in general (RAND - 36) <br /><br>- bony changes (scored as ordinal variable on panoramic, transpharyngeal, and transcranial Xrays).<br /><br> Possible confouders may be psychosocial factors related with chronic pain. These are scored with SCL-90.
