dc.description.abstractThis study aimed to compare soft tissue measurements derived from different imaging methods—lateral cephalometric radiographs, profile photographs, and three-dimensional (3D) stereophotogrammetry (3dMD) to evaluate the accuracy and consistency in orthodontic analysis. Thirty-four patients with no craniofacial deformities or a history of trauma were selected. Lateral cephalometric images were analyzed using WebCeph, profile photographs using GIMP, and 3D images with 3dMD Vultus software. Measurements included the nasolabial angle (NLA), labiomental angle (LMA), and facial convexity angle (Conv-A), as well as linear measurements obtained from 3dMD Vultus and WebCeph images. Intra-and inter-rater reliability were assessed using the Intraclass Correlation Coefficient (ICC). ANOVA and post hoc tests revealed that NLA values measured with 3dMD were significantly higher than those obtained with other methods (p<0.05). No significant differences were found in LMA values, while Conv-A measurements showed a statistically significant difference between GIMP and WebCeph (p<0.05). Linear measurements between WebCeph and 3dMD showed strong agreement (ICC>0.85). In conclusion, although two-dimensional (2D) methods provide clinically acceptable measurements, 3D stereophotogrammetry offers higher accuracy, particularly for critical soft tissue analyses. Based on these findings, it can be concluded that 3D imaging techniques were recommended for orthodontic and maxillofacial studies requiring precise soft tissue evaluation. Based on these findings, the null hypothesis regarding the nasolabial angle was rejected, while the hypotheses for the other angular and linear measurements were accepted. © 2025, Inonu University.
