Assessment of the accuracy and reliability of cephsmile v.2 in cephalograms and model measurements

Abstract

Objective: The study compared the measurement values from lateral cephalometric analysis, postero-anterior cephalometric analysis and study models between CephSmile version 2.0 and hand-traced method. Materials and Methods: Thirty sets of digital lateral, postero-anterior cephalograms and plaster models were selected randomly, uploaded and measured with CephSmile version 2.0 Program. All dental measurements were compared with manual measurements. Manual cephalometic measurements were obtained with a cepholomatic protractor and model measurements with vernier calipers. Both groups were assessed for accuracy and reliability. Mean and SD were calculated using SPSS version 11.0. Results: All CephSmile and hand-traced radiograph coefficients of variation were less than 0.10 suggesting high interexaminer reliability. No significant differences were found comparing lateral cephalograms, postero-anterior cephalograms, and plaster models between manual measurements and CephSmile Program version 2.0. Conclusion: CephSmile Software version 2.0 is as accurate and reliable as manual measurements for cephalometric analysis in orthodontic clinical treatment and planning. © 2012 Springer-Verlag GmbH.
