Background: Fractures of the mandibular angle are common in occurrence. The present study was conducted to assess correlation of mandibular gonial angle and mandibular angle fracture. Materials & Methods: 50 patients undergoing treatment for mandibular fractures underwent panoramic radiographs using Newtom Giano machine. The gonial angle was measured digitally by drawing the tangent to the posterior border of the ramus and tangent to the lower border of the mandible. Results: out of 50 patients, males were 30 and females were 20. Fracture was involving angle in 12, symphysis in 7, body in 5, parasymphysis in 20 and condyle in 6 cases. The mean gonial angle in cases with angle fracture was 117.2 degree, in symphysis fracture was 116.4 degree, in body fracture was 114.3 degree, in parasymphysis fracture was 117.1 degree and in condyle fracture was 117.8 degree. In 6 patients with high gonial angle, mandibular angle fracture was present in 4 cases. Relative risk was -0.51 and p value was less than 0.05. Conclusion: There was no correlation between mandibular gonial angle and mandibular angle fracture.
