Summary
WebCeph and AutoCAD show good reproducibility in cephalometric analysis. However, WebCeph has limitations, especially with automatic landmark identification, requiring cautious use in clinical practice.
Area of Science:
- Orthodontics
- Medical Imaging Analysis
- Computer-Aided Diagnosis
Background:
- Cephalometric analysis is crucial in orthodontics for diagnosis and treatment planning.
- Digital cephalograms are increasingly used, necessitating reliable analysis software.
- WebCeph offers a web-based solution, while AutoCAD is a widely used design software.
Purpose of the Study:
- To compare the accuracy and reliability of WebCeph with AutoCAD for digital cephalometric analysis.
- To evaluate the agreement and identify biases between the two software methods.
Main Methods:
- 50 digital lateral cephalograms were analyzed using WebCeph and AutoCAD.
- 17 landmarks and 11 skeletal, dental, and soft-tissue parameters were measured.
- Statistical analysis included paired t-tests, ICC, Bland-Altman plots, and linear regression.
Main Results:
- Both WebCeph and AutoCAD demonstrated adequate measurement reproducibility.
- Statistically significant differences were found for some angular and linear measurements (P < 0.05).
- While ICC showed good agreement, Bland-Altman plots revealed acceptable limits for only a subset of measurements, indicating proportional bias.
Conclusions:
- Automatic WebCeph has inherent issues with landmark identification and measurement consistency.
- Semi-automatic WebCeph shows improved performance but still requires cautious application in cephalometric analysis.
- AutoCAD serves as a reliable benchmark, highlighting areas for WebCeph improvement.
