Multi-Level Automated Classification of Temporomandibular Joint Degenerative Joint Disease on CBCT Using 3D Volumetric and 2D Slice-Based Approaches.

BACKGROUND Temporomandibular joint degenerative joint disease (TMJ DJD) causes progressive osseous changes of the mandibular condyle and articular fossa. Although cone-beam computed tomography (CBCT) enables detailed assessment, manual interpretation is time-consuming and subject to inter-observer variability. OBJECT...
