“…One of the main advantages of orthopantomogram is that there are no super impositions 8 . Orthopantomogram also shows both hemispheres of mandible and both gonial angle can be compared for any underlying pathological condition like condylar hyperplasia and condylar elongation 10 . Studies that observed the role of panoramic radiographs as a means of examining maxillary and mandibular relationships are lacking in orthodontic literature.…”

Objective: To evaluate the mean values of Genial angle measured by Lateral cephalogram and Orthopantomogram. Study Design: comparative cross sectional study. Place and Duration of Study: Armed Forces Institute of Dentistry, Rawalpindi, from Aug 2018 to Feb 2019. Methodology: Patients irrespective of gender between the ages of 13-20 who reported for the treatment of class I malocclusion with complete anterior dentition were included. Orthopantomogram and lateral cephalogram were drawn by the same person. Gonial angle on orthopantomogram was measured by drawing tangents on posterior border of ramus and lower border of mandible on both halves of orthopantomogram. On lateral cephalogram the angle was measured between ramus and mandible. Gonial angle measured from lateral cephalogram and orthopantomogram were compared. T-test was applied. Results: Mean age of the individuals was 18.33 ± 3.97 years. The mean gonial angle measured on lateral cephalogram was 122.66 ± 1.64 degrees while the mean gonial angle measured on right and left side of orthopantomogram was 122.41 ± 1.56 degrees and 122.33 ± 1.55 degrees respectively. Conclusion: Orthopantomogram can also be used to measure gonial angle as accurately as a lateral cephalogram with the advantage that there are no superimpositions and both the gonial angles can be measured simultaneously on orthopantomogram.

“…In Class III individuals , the gonial angle could influence therapy options and assist determine whether surgery is necessary [9,10]. While Kundi.et al [11] claimed that panoramic radiography may detect gonial angle in place of truthfully as a lateral cephalogram, Shahabi.et al [12] recommended foremost lateral cephalogram to estimate gonial angle. Additionally, several researchers discovered significant individual differences in gonial angle alteration, which had been influenced by age in addition of different forms of malocclusion [13,14].…”

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).

“…It is a constantly changing anatomical landmark in the head which can be measured clinically or radiographically. 3,4 Patient requiring an orthodontic treatment, and jaw surgeries are often subjected to extraoral radiographic investigations which includes panoramic adiography and lateral cephalogram. These radiographs can be used to evaluate the gonial angle easily by using modern digital software.…”

Introduction: Gonial angle measurements serve as an important parameter of the craniofacial complex and are usually studied on lateral cephalograms, but recently panoramic radiographs have also been used. The aim of this study is to measure the gonial angle using orthopantomogram and lateral cephalogram based on age, gender, ethnicity, and skeletal malocclusion in a tertiary care hospital. Methods: This is a descriptive cross-sectional study comprising 350 selected radiographs of apparently healthy individuals collected for a period of one year, from the Department of Oral Radiology of a tertiary care centre of Nepal. Gonial angle measurements were recorded from digital panoramic radiograph (both right and left side) and lateral cephalogram. Data was collected in terms of age, gender, ethnicity, and skeletal malocclusion and then statistically analysed using the Statistical Package for the Social Sciences version 20. Results: The mean gonial angle for panoramic right, left and lateral cephalogram was 122.490±7.570, 123.620±7.060, and 124.150±6.910, respectively. There was a decrease in the mean values of the gonial angle observed as age advances seen in all the radiographs. The gonial angle measured in Class III malocclusion was higher in all the radiographs, followed by Class II and Class I. Gonial angles obtained in females were higher than the males in all the radiographs. Finally, the Aryan population showed a higher gonial angle compared to the Mongolian population in all the radiographs. Conclusions: Panoramic radiograph (left side), could be considered as a reliable tool to measure the gonial angle.
