Abstract

Objective: The study aimed to compare the reliability of different cephalometric angles like the Beta, Yen, W and Pi angles to evaluate sagittal dysplasia in various skeletal patterns and assess the correlation between the variables.

Materials and Methods: 135 pre-treatment lateral cephalograms were taken and further divided into Class I, Class II and Class III groups. Each group had equal samples of 45 (n=45), based on ANB angle using Nemoceph software. Cephalometric landmarks Pi, Yen, Beta and W angle were identified and measured. Statistical analysis was done using the ANOVA test followed by Correlation coefficient analysis.

Results: Pi angle was highly predictable for differentiating class I cases, with 91.1% accuracy. Whereas in class II cases Pi and Beta angle were found to be most predictable with 73% and 66% accuracy respectively, while in class III cases Yen angle was found to be most predictable with 88% accuracy.

Conclusion: Overall Pi angle is considered the most reliable for assessing anteroposterior jaw relationship, followed by Beta and Yen angle.
