• Resumen

  • The aim of this study was to establish morphometrically a correlation of gonial angle size with condylar measures on Brazilian mandibles. For this purpose, we analyzed 220 mandibles. The measurements obtained were: length, in millimeters (mm), of each mandibular condyle (left/right), on two planes: anteroposterior and mesolateral; and gonial angle, in degrees (A°), on each side of the mandible. Data were analyzed using the Kolmogorov-Smirnov test, Pearson's test and the Mann-Whitney unpaired test, considering differences with p<0.05 as significant. The morphometric correlation of the parameters analyzed in the mandibles showed a statistically significant positive Pearson correlation. Our results support a multifactorial model of structural variations of the condyle and angle of the mandible, and these factors determine the morphological characteristics of the mandible. In addition, we suggest that they should be considered in clinical-surgical evaluations and be remembered during the procedures used for physiotherapy.
