ABSTRACT Objective: To evaluate the agreement between cephalometric measures obtained from two different software programs: Dolphin Imaging 11.7® and Radiocef Studio 2® . Methods: 30 digital lateral teleradiographies (200 dpi, 2100 x 2092 pixels) were analyzed on each of the software programs through demarcation of 11 cephalometric points by a single calibrated examiner. Then, the generated cephalometric magnitudes were statistically correlated by means of the intraclass correlation coefficients (ICC). Then 10 randomly selected radiographies were retraced on each of the programs in order to evaluate the intra-examiner concordance after a time interval of 08 days. Results: The SNB and Pog-NB magnitudes showed strong concordance between the software, while the SNA, ANB, 1-NA, 1-NB, 1.NB, 1.1 and Go-Gn.SN magnitudes unveiled moderate concordance. Only the 1.NA magnitude showed weak concordance. Conclusion: The software can be interchangeably applied in clinical practice.
