Abstract: PURPOSE: Use of cone-beam computer tomography (CBCT) to investigate the relationship between clinical symptoms, signs of adult temporomandibular joint osteoarthritis(TMJOA) and the imaging changes in order to provide reference for clinical diagnosis. METHODS: Eighty-one cases with CBCT images and clinical data were selected. Craniofacial items and TMJ images were measured by using Invivo 5 software and recorded. The final data were analyzed with SPSS 22.0 software package for Spearman rank correlation analysis. RESULTS: A significant correlation was found between Helkimo index and TMJ bony changes in condyle and glenoid fossa (P<0.01). However, no relationship with TMJ space changes was displayed (P>0.05). CONCLUSIONS: Use of CBCT to observe TMJOA bony changes (include mandibular condyle, joint fossa) is helpful for the diagnosis and judgment of disease severity, but not for displaying temporomandibular joint space changes.
