Is it essential to recognize the gonial angle in orthodontics using panoramic radiography?

Abstract

Background: In orthodontic therapy as well as the craniofacial complex, the outside gonial Angle is a critical angle. Because lateral cephalometric radiographs show superimposed representations of anatomical structures, including gonial angle; The purpose of this research would have been to compare panoramic as well as lateral cephalometric radiographs in order to evaluate gonial angle within angle classifying. Materials and Methods: The current study included 64 individuals (29 males and 35 females) ranging in age from 15 to 30 years. The individuals have been chosen retrospectively from the dental and skeletal Classes I, II, as well as III malocclusion groups. Mandibular as well as Ramal planes have been drawn then based on these planes that used a lateral cephalometric radiograph. To calculate the gonial angle, two tangents had been derived from the mandible lower border, the condyle's posterior margins, in addition the ramus on individually sides of panoramic radiographs. The variations between the three angle groups have been examined using several pairwise comparisons (ANOVA). Results: There have been no significant variations in gonial angles evaluated using lateral cephalometric radiography as well as panoramic radiography between the Classes I, II, as well as III malocclusion groups (P>0.05).
