Temporomandibular Disorder (TMD) is the main cause of pain of non-dental origin in the orofacial region. The etiology and the pathophysiology of TMD is poorly understood. It is generally accepted that the etiology is multifactorial, involving a large number of direct and indirect causal factors.  The attention of the orthodontic community regarding TMD was heightened in the late 1980s after litigation involving orthodontic treatment as the cause of TMD in orthodontic patients. Because orthodontic treatment lasts around 2 years, orthodontic patients may complain about TMD during or after treatment and orthodontists may be blamed for causing TMD by unsatisfied patients, so it is critical for orthodontics to determined TMDs; However it cannot be reliably assessed by a clinical examination. Nowadays large numbers of imaging techniques are available to visualize the temporomandibular joint and surrounding structure.
This study reviewed the literature on imaging of temporomandibular joint disorders. A PUBMED search (National Library of Medicine, NCBI; revised 1 April 2012) from1985 to 2012 was conducted. This search revealed 83 papers, which were screened in detail.
The purpose of this article is to conduct a narrative review of current evidence regarding the understanding of temporomandibular disorders by radiographic evaluation.
