- The gonial angle (mandibular angle) is a radiomorphometric index from the angle of the mandible, which is formed between the inferior border and the posterior border of the mandible. The mandible is one of the causes of various forms of malocclusion. This study was conducted to determine the changes and differences of gonial angle of each age group in Mongoloid race in Medan City in terms of lateral cephalometric radiograph. The type of this research is analytical using cross-sectional design at Oral and Maxillofacial Radiology Installation of Dental Faculty of Dentistry, University of Sumatera Utara (USU), with sample of 150 people divided into five age groups. This research describes that the result of the largest sequential goni sequence were found in the age group 4-12 years (127,43o), age> 60 years (126.61o), age 35-60 years (124.82o), age 25-34 years (122.10o), and the age of 13-24 years (119.96o). The conclusion of this study is that there is a significant difference from the gonial (mandibular angle) of each age group, on Mongoloid race in Medan City in terms of lateral cephalometric radiographs where the change of gonial angle is estimated by the effect of the teeth and age conditon.
