Reliability of kinesiography vs magnetic resonance in internal derangement of TMJ diagnosis: A systematic review of the literature

Objective: The aim of this systematic review was to evaluate the accuracy and the diagnostic reliability of kinesiography and magnetic resonance imaging (MRI) in diagnosis of patients presenting temporomandibular disorders. Methods: A literature survey carried out through PubMed, SCOPUS, LILIACS, and the Cochrane Library from the inceptions to the last access on August 18 2016 was performed to locate randomized clinical trials, controlled trials, prospective cohort studies, or retrospective studies (with or without a control group), that examined the diagnostic reliability of recording devices of mandibular movements in comparison to MRI. Results: From the results, it was found that a significant correlation between these electronic devices and MR images could not be detected in case of disc displacement. Discussion: The scientific evidence does not support the usefulness in clinical practice of the jaw-tracking devices to diagnose temporomandibular disorders because their diagnostic reliability is poor.
