  • Purpose: To determine if Temporomandibular Joint bony changes are correlated with self-reported pain, limitation in range of motion, crepitation, pain on palpation and jaw use. Materials and Methods: Clinical data and Cone Beam Computed Tomography images of 30 patients with TMJ osteoarthritis at the UNC School of Dentistry Orofacial Pain Clinic were analyzed. Koyama's1 and Ahmad's2 criteria were used to classify the condylar bony changes. Clinical measures included pain rating and mandibular range of motion. Generalized Linear Modeling was used to correlate the clinical and radiographic findings. Spearman's Rho was used to correlate Koyama's with Ahmad's classifications. Results: Correlation between the maximum condyle change and verbal pain rating and mandibular range of motion was poor. However both the Koyama and RDC/TMD classifications were highly correlated for average and maximum bony change. Conclusion: The findings of this study do not support the use of radiographs alone for diagnosis and treatment planning.
