[Necessity and normalization of imaging examination on temporomandibular disorders]

Diagnosis and treatment of temporomandibular disorders (TMD) have been paid attention greatly by dentists in clinic. Imaging is the most important method for dentists to diagnose TMD correctly. Cone-beam CT (CBCT) and MRI have been demonstrated superiority and necessity that contribute to correctly diagnosis, early diagnosis and follow-up patients. However, there are several significant problems required for professional agreement: the procedures for CBCT and MRI examination need to be standardized; dentists have to be trained regularly for the knowledge of the imaging diagnosis of TMD; it should be emphasized that patient history and clinical examination are much more important for diagnosis, imaging is only a supplement and should not be over used.
