Since the advent of the first dental X-ray machine in 1919, radiographies have been used for several purposes, including diagnosis, evaluation of pathologies, periapical lesions, tooth resorptions and evaluation of existing endodontic and restorative treatments.Ĭephalometrics appeared as an evolution of craniometry from the standardization o radiographic techniques and development of the cephalostat proposed by Broadbent in 1931.

The computerized method using the Dentofacial Planner software showed the highest reliability, followed by the manual method, while the Dolphin Imaging software was the least effective and more likely to produce systematic errors in the identification of points. Results: The results showed statistically significant differences, especially between measurements evaluated on the Dolphin software and by manual tracing (p>0.05).Ĭonclusions: According to the present results, the three cephalometric methods have proven to be accurate, since they presented few systematic errors.
For analysis of results, the dependent t test was used to compare the error of each method (intragroup error) comparison of measurements between the three methods was performed by the one-way ANOVA and Tukey test in the presence of significant result. A calibrated operator conducted 90 manual and 180 digital cephalometric tracings, using 8 angular measurements (SNA, SNB, ANB, FMA, 1.NA, 1.NB, SN-Occlusal, SN-GoGn) and 5 linear measurements (1-NA, 1-NB, Co-Gn, Co-A e LAFH).
Methods: The sample comprised 45 lateral cephalograms. Objective: To evaluate and compare the error in cephalometric measurements by manual and computerized methods using the softwares Dolphin Imaging version 11.0 and Dentofacial Planner version 7.02.
