Criterion Validity of the Newly Developed Occlusal Cant Index

Int J Environ Res Public Health. 2022 Sep 15;19(18):11623. doi: 10.3390/ijerph191811623.

Abstract

Objectives: To assess the criterion-related (concurrent) validity of the newly developed occlusal cant index (OCI).

Materials and methods: Four standardized posterior-anterior (PA) cephalometric radiographs of four patients were obtained at a 0° occlusal cant (OC) and manipulated to create various degrees of OC from 1° to 4° on the right and left sides, with a total of 36 PA images. The angle between the actual horizontal line and the occlusal plane was manually drawn on each PA radiographic image. The set of radiographic images was displayed to 36 orthodontists, who were asked to measure the drawn angle and apply the OCI to each PA radiographic image.

Results: The overall criterion-related validity of the OCI was statistically significant among all grades.

Conclusion: The OCI is highly valid and recommended for clinical consideration.

Keywords: criteria validation; index; index development; occlusal cant.
