Objective: The purpose of this study was to compare angular and linear cephalometric measurements obtained through manual and digital cephalometric tracings using Dolphin Imaging® 11.0 software with lateral cephalometric radiographs. Methods: The sample consisted of 50 lateral cephalometric radiographs. One properly calibrated examiner performed 50 manual and 50 digital cephalometric tracings using eight angular measurements (FMA, IMPA, SNA, SNB, ANB, 1.NA, 1.NB, Y-Axis) and six linear measurements (1-NA, 1-NB, Co-Gn, Co-A, E Line-Lower lip and LAFH). Results were assessed using Student’s t-test. Results: The results showed no statistically significant differences in any of the assessed measurements (p> 0.05). Conclusions: Conventional and computerized methods showed consistency in all angular and linear measurements. The computer program Dolphin Imaging® 11.0 can be used reliably as an aid in diagnosing, planning, monitoring and evaluating orthodontic treatment both in clinical and research settings.
