Abstract


Background: This study aimed to evaluate the reliability of AutoCAD program in cephalometric analysis in comparison with View-

box 3.1.1 cephalometric computer software.

Materials and method: The sample consisted of 30 digital true lateral cephalometric radiographs of some under- and postgradu- ate students in the College of Dentistry/ University of Baghdad. Seventeen parameters (11 angular and 6 linear) were measured using the Viewbox 3.1.1 cephalometric computer software and re-measured using AutoCAD program. Descriptive statistics were performed for each parameter and paired samples t-test was obtained to evaluate the difference between both of the methods.

Results: The results revealed the presence of non-significant difference between both softwares.

Conclusions: Cephalometric analysis with AutoCAD program was comparable with Viewbox 3.1.1 software and both of them de- pend on the landmarks identification by the observer. AutoCAD software is available in Iraq unlike the other softwares and it can be used in clinical diagnosis also suited for research projects.
