  https://www.aafp.org/pubs/afp/issues/2015/0315/p378.html

  Temporomandibular disorders (TMD) are a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint complex, and surrounding musculature and osseous components. […] Diagnosis is most often based on history and physical examination. Diagnostic imaging may be beneficial when malocclusion or intra-articular abnormalities are suspected. […] The diagnosis of TMD is based largely on history and physical examination findings. The symptoms of TMD are often associated with jaw movement (e.g., opening and closing the mouth, chewing) and pain in the preauricular, masseter, or temple region. […] Physical examination findings that support the diagnosis of TMD may include but are not limited to abnormal mandibular movement, decreased range of motion, tenderness of masticatory muscles, pain with dynamic loading, signs of bruxism, and neck or shoulder muscle tenderness.

  There is no widely accepted, standard test available to diagnose TMDs. Because the exact causes and symptoms are not clear, identifying these disorders can be difficult. […] Your doctor or dentist will note your symptoms and take a detailed medical history. He or she will ask questions about your pain, including its location, when it occurs, what makes it better or worse, and if it stays in one area or spreads to other parts of your body. The doctor or dentist will also ask if you have other pain conditions such as headache or back pain. […] He or she also will examine your head, neck, face, and jaw for tenderness; jaw clicking or popping; or difficulty with movement. The doctor or dentist might also suggest imaging studies such as an x-ray, magnetic resonance imaging (MRI), or computed tomography (CT). […] Pain in the mouth, jaw, or face may or may not be related to TMDs. Your doctor or dentist may have to rule out other conditions before diagnosing a TMD.

  In this article well explore three primary tests to help diagnose temporomandibular disorders: […] A panoramic radiograph is utilized primarily to have a general vision of the maxillaries. For the TMJ, it is possible to do an initial evaluation of the condylar shape, presence of subchondral erosion, cysts, flattening and erosion. […] A computerized tomographic image (CT) mostly utilized to evaluate a bony or soft tissue lesions. Some examples are growths, tumors, and bone infections or reaction in the maxilla or mandible. […] An MRI is indicated for the TMJ when an image of the disc is required. Usually as a baseline or as a follow up for a DDNR. It is the image of choice with there is an acute onset loss of motion of the jaw, prior to decide on a major occlusal therapy. […] A strategy to differentiate between a muscle and joint-related reduced range of motion of the jaw is to use passive stretching.

  Imaging can assist in the diagnosis of TMD when history and physical examination findings are equivocal. […] The initial study should be plain radiography (transcranial and transmaxillary views) or panoramic radiography. […] Magnetic resonance imaging is the optimal modality for comprehensive joint evaluation in patients with signs and symptoms of TMD. […] Injections of local anesthetic at trigger points involving the muscles of mastication can be a diagnostic adjunct to distinguish the source of jaw pain.

  Diagnosis of subluxation is based on history alone; with the other intra-articular TMD, both the history and exam criteria must be met. […] When any of those diagnoses need to be confirmed, imaging criteria apply. […] Imaging (reference standard for this diagnosis): TMJ MRI shows that in the maximum intercuspal position, the posterior band of the disk is located anterior to the 11:30 position and the intermediate zone of the disk is located between the condylar head and the articular eminence. […] Imaging: Criteria are the same as for disk displacement with reduction, if intermittent locking is not present at the time of imaging. If locking occurs during the imaging study, it renders an imaging-based diagnosis of disk displacement without reduction, and clinical confirmation of reversion to intermittent locking is needed.

  The Most Important Thing You Can Do For Your Patient is to Make the Correct Diagnosis. It is the Foundation For Success. The key to understanding Temporomandibular Disorders is to realize that they present along a broad continuum, from relatively minor muscular conditions to very complex disorders involving intracapsular mechanical dysfunction, usually combined with significant muscular involvement.
