Brief Summary
|
This study aims to compare the effectiveness of MSG angle and R angle with Jarabak’s ratio in predicting vertical skeletal discrepancies using cephalometric radiographs. A total of 120 orthodontic patients will be assessed and grouped based on Jarabak’s ratio for comparative evaluation. |
