Evaluation of Accuracy of Manual and Digital Tracing with Lateral Cephalometric Radiograph: A Comparative Study

Abstract

Objective: To assess the accuracy of cephalometric measurements performed with (WEBCEPH analysis software 1.0.0) with lateral cephalometric radiographs based on measurement obtained from manual tracing. Materials and Methods: 50 patients' pre-treatment lateral cephalograms using the same digital cephalometer was collected. Tracings were performed digitally and by hand. 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). The same investigator performed all of the tracings; Results were assessed using Student’s t-test. Result: There was no statistically significant difference between Hand and digital tracing (p>0.05). Conclusion: WEBCEPH cephalometric tracing showed good agreement with manual tracings.
