Abstract

Background: This study aims to find correlation between angular and linear cephalometric measurements used to assess sagittal skeletal discrepancy. Methods: Sixty subjects, aged 15–25 years, were studied and their cephalograms were traced, and ANB angle, Wits appraisal, and Beta angle, YEN angle and W angle, and dentoskeletal overjet were measured to detect correlation among them and Pearson correlation coefficient was used to calculate correlation coefficients between various parameters. Results: Beta angle showed negative linear correlation −0.5, −0.673, and −0.352 in conjunction with ANB angle and Wits appraisal and dentoskeletal overjet, respectively. The W angle had a negative significant relation −0.492 with ANB angle and a positive significant relation 0.475, 0.527 with Beta angle and YEN angles, respectively. Dentoskeletal overjet had a positive correlation 0.328 and 0.494 with ANB angle and Wits, respectively, and negative correlation −0.558, −0.588, and −0.352 with YEN angle, Beta angle, and W angle, respectively. Conclusion: A negative linear correlation was found for Beta angle with ANB angle, Wits appraisal, and dentoskeletal overjet. In the same way, the W angle had a negative significant relation with ANB angle but, a significant positive relation with Beta angle and YEN angles.
