Diagnostic Accuracy of Jaw Motion Analyzer Versus Research Diagnostic Criteria and Magnetic Resonance Imaging for Temporomandibular Disorders: A Pilot Study

The goal of this diagnostic accuracy study is to determine the diagnostic accuracy of jaw motion analyzer(JMA) in terms of sensitivity and specificity with target cut of points used by valid reference standards which will be the research diagnostic criteria(RDC/TMD) and magnetic resonance imaging(MRI) for Temporomandibular disorders(TMDs).

The main questions the study aim to answer are :

• Does the actual precision of JMA which will achieve the target cut off diagnostic values in diagnosing TMDs ?
• How much accuracy values to be achieved by JMA compared to RDC/TMD and MRI as reference standards ?

Researchers will determine the precision values of JMA for patients with chronic orofacial pain for targeting TMDs and compare with valid diagnostic reference standards which are the RDC/TMD and MRI.

Participants with chronic orofacial pain will undergo through two diagnostic interventions in two separate visits with one week interval; first visit will be intraoral scan(IOS) for both upper and lower dental arches with bite registration followed with IOS import in JMA (WINJAW+3.0, Zebris GmbH Germany) to measure the trajectory of mandibular movements and condylar path tracking and accordingly both functional and EPA reports will be extracted to obtain both graph tracing records of both mandibular and condylar path trajectories. On the second visit, participants will be examined by the RDC/TMD clinical examination based algorithms to diagnose TMDs and MRI will be used as confirmative approach.
