Abstract
Purpose To determine age-related differences in size and shape of the mandibular condyle in children to establish anatomical reference values.
Material and Methods 420 mandibular condyles of 210 children (mean age, 7 years) were retrospectively analyzed using computed tomography (CT) imaging and the greatest left-right (LRD) and anterior-posterior (APD) diameters and the anteversion angle (AA) were measured by two readers independently. An APD/LRD ratio was calculated. The shape of the condyles was graded into 3 types on sagittal images. Correlations of parameters with the children’s age were assessed using Pearson correlation analyses.
Results The LRD (mean, 14.1±2.4mm), APD (mean, 7.3±1.0mm), and LRD/APD ratio (mean, 1.9±0.3) increased (rLRD=0.70,p
