Introduction: The present study was aimed at comparing the accuracy of cephalometric tracing in by the manual, semi-digital, and fully digital cephalometric tracing methods in orthodontics.
Materials and Methods: The present study was conducted in the department of orthodontics of a tertiary care government hospital with clearance from the Institutional Ethical Committee. Thirty lateral cephalograms were evaluated using three different method: Group I-Print of lateral cephalogram was traced manually on an acetate sheet. Group II-the digital images of cephalograms were traced on screen using the NNT (NewTom Image Viewer) software. Group III-digital images traced using Nemoceph™ software. Ten angular and eight linear variables were measured. Inter-group comparison was made using one-way ANOVA measure followed by post hoc Tukey's Honest Significant Difference test.
Results: Intra-class correlation coefficients showed acceptable agreement in all three groups, i.e., Group I (0.281), Group II (0.11), and Group III (0.056). The one-way ANOVA test revealed a significant difference between groups for two variables. i.e., “EL-Max” and “EL-Mand.” The difference was present between Groups I and II i.e., “EL-Max” (P < 0.000) and “EL-Mand” (P < 0.02) respectively.
Conclusion: The present study found no significant difference between manual, semi-digital, and fully digital cephalometric tracing with good agreement among all variables except two linear variables, which were traced more accurately in semi-digital method. The preference of using on particular technique can be based on the availability, expertise, and ease of availability.
