Our first aim was to investigate whether Panoramic Radiography or Lateral Skull Projection images with lower radiation dose can be used instead of Cone Beam Computed Tomography in the diagnosis of vertical condylar fractures. The second aim of the study was to compare observers' capabilities in diagnosing these fractures. Materials and Methods: A sample consisting of 15 fresh cadaver mandibles with 30 condyles frozen within 24 hours post-mortem was randomly selected. Vertical fractures from the lateral 2/3 of the condyle head with 0.5 (10 condyles) and 1mm (10 condyles) thickness were created using a fret saw. After creating condyle fractures, digital panoramic, LSP, and CBCT images were acquired. Two dentomaxillofacial radiologists with 15 years of experience, two dentomaxillofacial radiologists with five and seven years of experience, and two newly graduated dentists have evaluated the images. The success of the observers in diagnosing the vertical condyle fracture in each imaging method, intra-observer and inter-observer agreement was evaluated. Results: The success of all dentists in determining the condyle fractures using LSP images was higher than the success they achieved using panoramic images, but the sensitivity values of LSP and panoramic radiographs for detecting vertical condyle fractures were found to be below 50%. Using different imaging options with CBCT, all diagnoses made by new graduates and dentomaxillofacial radiologists with five and 15 years’ experience were 100% compatible with the gold standard (AC1: 1 (1–1)). Conclusions: For the diagnosis of vertical condyle fractures, conventional techniques (panoramic and lateral jaw imaging methods) were found to be insufficient.
