Title Diagnostic Evaluation of Temporomandibular Joint Osteoarthritis using Cone Beam Computed Tomography Compared With Conventional Radiographic Technology
Clinical Question In Patients with possible osteoarthritis of the temporomandibular joint (TMJ), how effectively will panoramic radiography produce an image diagnostic of osteoarthritis as compared to cone beam computerized tomography (CBCT)?
Clinical Bottom Line No significant difference in image accuracy was detected between panoramic radiography and CBCT.

Comments on
The Evidence
Although the number of subjects is favorable, no mentions are made of blinding in data interpretation- the lack of which could have potentially skewed data due to confirmation bias.
Applicability This study could prove useful for monitoring the treatment of patients suffering from TMJ osteoarthritis. The lower cost and suitable accuracy of panoramic radiography would make continued panoramic monitoring of the TMJ a more viable option for lower-income patients.
