Evaluation of mandibular asymmetry in angle malocclusion samples by posterioanterior cephalometric radiography: A preliminary study

Objectives: The aim of this study was to evaluate the effect of different occlusion types on mandibular asymmetry in different anatomical points using posteroanterior cephalometric radiography. Materials and Methods: This study was retrospectively conducted on 100 patients whose posteroanterior imag...

description Objectives: The aim of this study was to evaluate the effect of different occlusion types on mandibular asymmetry in different anatomical points using posteroanterior cephalometric radiography. Materials and Methods: This study was retrospectively conducted on 100 patients whose posteroanterior images and malocclusions were registered in a patient database. Asymmetry indices were determined using four linear measurements on images, and the effect of malocclusions, age, and gender on these asymmetry indices was investigated. P
