Objective The aim of this study was to find the applicability of the CentroGraphic analysis to evaluate the skeletal, dental, and soft tissue morphologic characteristics of Egyptian adult sample with different classes of malocclusion, and to compare the CentroGraphic analysis with the conventional cephalometric measurements. Patients and methods A sample of 208 lateral cephalometric radiographs, of Egyptian orthodontic patients with age ranging from 18 to 25 years old, was analyzed twice by both the CentroGraphic and the conventional methods. Ten cephalometric measurements were assessed and the findings of which were compared with those of the CentroGraphic analysis. χ2-test was applied to test the statistical relationship between them. Results A nonsignificant statistical relationship was found between both the methods in evaluating the anteroposterior skeletal positions of maxilla and mandible. Regarding the vertical skeletal pattern, a nonsignificant relationship upon comparing the mandibular plane (SN/MP) angle with the position of the facial centroid (FC), a significant relationship between angle y-axis to the Frankfort horizontal plane and position of FC, and a highly significant relationship between the ratio of lower anterior facial height to the total face height and the position of the FC were revealed. Highly significant relationships were evident on comparing both methods for evaluating the axial inclinations of the upper and lower incisors. Highly significant relationships were found between both methods for the assessment of upper and lower lips. Conclusion The CentroGraphic analysis is a quick and easy method of analysis of the cephalometric radiographs that can be used as an adjunctive method to evaluate the vertical skeletal, dental, and soft tissue morphologic characteristics of Egyptian adults.
