Studies have shown that tomography of the TMJ provided supplementary information that supersedes what is obtainable from clinical examination alone.<ref>{{cite journal | vauthors = Wiese M, Wenzel A, Hintze H, Petersson A, Knutsson K, Bakke M, List T, Svensson P | display-authors = 6 | title = Osseous changes and condyle position in TMJ tomograms: impact of RDC/TMD clinical diagnoses on agreement between expected and actual findings | journal = Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics | volume = 106 | issue = 2 | pages = e52-63 | date = August 2008 | pmid = 18547834 | doi = 10.1016/j.tripleo.2008.03.021 }}</ref> However, the issues lies in the fact that it is impossible to determine whether certain patient groups would benefit more or less from a radiographic examination.<ref>{{cite journal | vauthors = Petersson A | title = What you can and cannot see in TMJ imaging--an overview related to the RDC/TMD diagnostic system | journal = Journal of Oral Rehabilitation | volume = 37 | issue = 10 | pages = 771–8 | date = October 2010 | pmid = 20492436 | doi = 10.1111/j.1365-2842.2010.02108.x }}</ref>
 
The main indications of [[CT scan|CT]] and CBCT examinations are to assess the bony components of the TMJ, specifically the location and extent of any abnormalities present.<ref name=":7">{{cite journal | vauthors = Ferreira LA, Grossmann E, Januzzi E, de Paula MV, Carvalho AC | title = Diagnosis of temporomandibular joint disorders: indication of imaging exams | journal = Brazilian Journal of Otorhinolaryngology | volume = 82 | issue = 3 | pages = 341–52 | date = May 2016 | pmid = 26832630 | doi = 10.1016/j.bjorl.2015.06.010 | pmc = 9444643 | doi-access = free }}</ref><ref name=":8">{{cite journal | vauthors = Klatkiewicz T, Gawriołek K, Pobudek Radzikowska M, Czajka-Jakubowska A | title = Ultrasonography in the Diagnosis of Temporomandibular Disorders: A Meta-Analysis | journal = Medical Science Monitor | volume = 24 | pages = 812–817 | date = February 2018 | pmid = 29420457 | pmc = 5813878 | doi = 10.12659/MSM.908810 }}</ref><ref>{{cite journal | vauthors = Al-Saleh MA, Alsufyani NA, Saltaji H, Jaremko JL, Major PW | title = MRI and CBCT image registration of temporomandibular joint: a systematic review | journal = Journal of Otolaryngology - Head & Neck Surgery | volume = 45 | issue = 1 | pages = 30 | date = May 2016 | pmid = 27164975 | pmc = 4863319 | doi = 10.1186/s40463-016-0144-4 }}</ref>
 
The introduction of cone beam computed tomography (CBCT) imaging allowed a lower radiation dose to patients, in comparison to conventional CT. Hintze et al. compared CBCT and CT techniques and their ability to detect morphological TMJ changes. No significant difference was concluded in terms of their diagnostic accuracy.<ref>{{cite journal | vauthors = Hintze H, Wiese M, Wenzel A | title = Cone beam CT and conventional tomography for the detection of morphological temporomandibular joint changes | journal = Dento Maxillo Facial Radiology | volume = 36 | issue = 4 | pages = 192–7 | date = May 2007 | pmid = 17536085 | doi = 10.1259/dmfr/25523853 }}</ref>
