Aim: to evaluate the cephalometric software Radiocef 2.0 regarding reliability and precision, as compared to the conventional manual tracing and measuring procedures, and to the software Dentofacial Planner 7.02 (Gold Standard). Methods: the sample consisted of 50 good quality lateral head films from patients of both gender at the 11 to 24-year age range belonging to the files of the orthodontic graduate clinic at Bauru Dental School, University of São Paulo. The radiographs were traced and measured by different methodologies generating four groups as follows: Group 1 (the radiographs were manually traced and measured); Group 2 (the cephalograms and landmarks were scanned and measured with Radiocef 2.0 software); Group 3 (the radiographs were scanned and measured with Radiocef 2.0 software); and Group 4 (the landmarks were digitized and measured with Dentofacial Planner 7.02 software). Linear and angular measurements were performed and an analysis of variance and a Kruskal-Wallis test were conducted for intergroup comparison. Results: results demonstrated no statistically significant differences between the groups. Conclusions: the software is reliable to be used for clinical and investigative purposes and that Radiocef 2.0 can be used by either scanning the cephalograms and landmarks or by scanning the radiograph itself.
