The agreement between magnetic resonance imaging and arthroscopic findings in temporomandibular joint disorders

The aim of this retrospective observational study was to assess the potential agreement between independent magnetic resonance imaging (MRI) and arthroscopic findings their respective contributions a final diagnosis in patients with refractory temporomandibular joint disorders. Two dentomaxillofacial radiologists two oral maxillofacial surgeons scored 50 joints. All observers, who were blinded additional clinical information, used specific scoring form selected one or more diagnostic labels. Agreement MRI arthroscopy assessed as primary outcomes using Fleiss’ kappa. Intra-modality correlation signal intensity ratio (SIR) measurements on synovitis grading secondary outcomes. poor.
