Evaluation of the Reliability of the ViCeph Automatic Cephalometric Analysis Software (Viet Nam)

Abstract

    Cephalometric analysis plays a crucial role in diagnosing and planning orthodontic treatment. This study compares the distance and angular measurements obtained using the traditional manual tracing method and the ViCeph automatic cephalometric analysis software (Viet Nam). A total of 10 indices, including 6 skeletal indices, 3 dental indices, and 1 soft tissue index, were analyzed using both methods on 300 digital lateral cephalometric radiographs. The Intraclass Correlation Coefficient (ICC) was used to assess the level of agreement between the two methods. The results demonstrated a moderate to high level of agreement across all indices. For skeletal parameters, ICC values ranged from 0.87 to 0.96, except for the mandibular arch which had an ICC of 0.75 (95% CI: 0.68˗0.79). For dental parameters, ICC values ranged from 0.72 to 0.89, with lower incisor protrusion reaching 0.89. The interincisal angle and L1-A-Pog (angle) had ICC values of 0.82 and 0.72, respectively. For soft tissue analysis, the lower lip–E plane aesthetic line showed the highest ICC, reaching 0.94 (95% CI: 0.93˗0.96). These findings suggest that the ViCeph software is an effective and time-saving tool for cephalometric analysis, demonstrating a high level of agreement with the traditional method. However, further studies are needed to validate the reliability of the L1-A-Pog angle measurement.
