    Introduction: Morphological changes of the condyle are a sequel of orthodontic treatment which can be noted radiographically. Morphological changes can be either in the form of condylar remodeling or resorption. Condylar resorption is an idiopathic condition and affects female more common, with a female-to-male ratio of 9:1. A number of diseases can cause condylar resorption which includes osteoarthritis, reactive arthritis, and avascular necrosis. Condylar resorption is characterized by severe morphologic changes with decreased condylar configuration and volume and decreased ramus height, therefore leading to relapse after orthodontic treatment. Objective: The aim of the study was to evaluate the morphological changes in the head of the condyle following orthodontic treatment. Materials and Methods: The post- and pre-operative records were collected from 20 patients who underwent orthotreatment in the Department of Orthodontics, Saveetha Dental College, Chennai. For radiographic evaluation of condylar changes (resorption), orthopantamograph (OPG) was advised. The post- and pre- treatment OPG were traced using tracing paper, in which a ramus tangent and a line perpendicular to it through the superior point of the condyle were drawn. The distance from the top of the condyle to the inferior point of the tangent was measured as the height of the ramus. Height-to-width ratio of the condyle was measured. The surface of the condyle was subdivided into superior, anterior, and posterior part. Condyle was classified based on modified Kranjenbrink classification. Data obtained were analyzed and the results were obtained. Results: The result revealed that, of 20 patients, 19 patients had condylar remodeling.Conclusion: It is concluded from our study that orthodontic treatment over a long period of time can cause changes in the morphology of the mandibular condyle.
