Abstract

Newer diagnostic methods have become widespread in medicine nowadays as a result of extraordinary advancements in the field of electronics. On computers, various orthodontic programs are available as software. When it comes to orthodontics, diagnosis is critical, with the radiographic study being the most important phase. The goal of this research was to assess the level of liability of direct digital radiograph tracing using CephX and compare with hand tracing digital printouts and evaluate the two techniques concerning measurement reproducibility of individual methods. The material consisted of 25 digital lateral cephalometric images, fourteen linear and angular parameters were measured by a single operator digitally and manually. The intraclass correlation coefficient and confidence interval were used to compare the difference of the measurements obtained from manual and digital tracings, and intra-examiner error was evaluated by the coefficient of variation. A comparison of hand and CephX tracing showed a low level of agreement in the anterior facial height, anterior and posterior cranial base length. Only of (LI to A-Pog) line for both manual and digital methods showed poor intra-examiner duplicability. Thus, it can be concluded that digital tracing with CephX is adequate for clinical uses and similar to manual cephalometric tracings.
