# Assessing sagittal discrepancies using beta angle, ANB angle and WITS appraisal: A cephalometric study

## TL;DR

This study compares three tools for assessing jaw discrepancies and finds the beta angle to be more reliable than the others.

## Contribution

The beta angle is shown to be more consistent than the ANB angle and Wits appraisal in assessing sagittal jaw relationships.

## Key findings

- Beta angle measurements showed significant differences between Class I, II, and III skeletal groups.
- Beta angle is more reliable in cases with jaw rotations or occlusal plane changes.
- The study recommends further validation with larger and diverse populations.

## Abstract

There is a need to evaluate the reliability and applicability of various cephalometric tools used for assessing sagittal discrepancies
in patients with Class I, II, and III skeletal patterns. Therefore, it is of interest to assess sagittal discrepancies in patients with Class
I, II, and III skeletal patterns by comparing three common diagnostic tools: the beta angle, ANB angle and Wits appraisal. Hence, a total of
120 subjects, divided into three groups based on their skeletal pattern, were evaluated using lateral cephalograms. Statistical analyses showed
significant differences in beta angle measurements between the groups. The beta angle was found to provide a more consistent assessment
of sagittal jaw relationships than the ANB angle and Wits appraisal, especially in cases with jaw rotations or occlusal plane changes.
Thus, we show the beta angle as a valuable tool for orthodontic diagnosis, offering greater reliability in assessing skeletal relationships.
Further research with larger samples and different populations is recommended to validate these findings.
