Objective: The purpose of our randomized study was to compare the skeletal and dental values in open bite cases using lateral cephalometric analysis and panoramic X-rays analysis and to evaluate if PR is a reliable diagnostic method in skeletal malocclusions.Methods: 21 (6 boys, 15 girls) patient with skeletal open bite were selected and both radiological examinations were performed. “Modified cephalometric analysis” on panoramic X-rays and Steiner’s cephalometric analysis was performed using AudaxCeph software. Statistical analysis was performed using the Pearson correlation method and SPSS statistical software for comparison.Results: Skeletal values like anterior facial height (AFH), angles between Frankfort horizontal and mandibular/palatal plane (ML/H and NL/H) showed no statistical significance, mandibular plane/ramus tangent angle (goniac angle) and mandibular plane/palatal plane angle (ML/RL, ML/NL) showed high or moderate (posterior facial height - PFH) significant statistical interrelation (r=0.46-0.80). Almost all dental parameters were statistically significant, from moderate to high (r=0.56-0.79). The only statistically insignificant dental parameter was the mesial cusp tip of the upper first molar/palatal plane (ms-NL) distance (r=0.32). Vertical skeletal and dental parameters on panoramic X-rays can moderately approximate lateral cephalomteric values. This means that mostly in skeletal malocclusions, panoramic X-rays cannot be used for quantitative determination of the parameters.
