[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.目前，颞下颌关节紊乱病的诊断和治疗已越来越引起广大口腔医师的重视。影像学检查是明确诊断的主要辅助手段，其中锥形束CT和MRI检查结果对临床的重要性更显示其必要性，如明确诊断、认识疾病；早期诊断、早期治疗；随访追踪、精准治疗。但目前仍有一些突出的问题需要不断改进和完善，并获得共识，如检查方法需进一步规范，资料需能共享；医师自身需不断学习和培训，以提高阅片水平；需重视患者的病史和临床检查，避免过度的影像学检查等。.
