Abstract
The present study was undertaken to evaluate the prevalence of radiographic changes in the condylar morphology and its association with age, clinical signs and symptoms of temporomandibular dysfunction and dentition status and also to evaluate the intra examiner and inter examiner reliability in assessing condylar changes using panoramic radiographs. A total of 75 subjects were recruited for the study. They were divided into 3 age groups. 20–40 yrs (Group A), 41–60 yrs (Group B) and 61 yrs and above (Group C). In each age group 25 subjects were evaluated both clinically and radiographically. The prevalence of radiographic changes in condylar morphology and symptoms of temporomandibular dysfunction was 81.3% and 18.6%, respectively. Radiographic abnormalities in the mandibular condylar morphology increased with age. They were seen more frequently in patients with clinical signs and symptoms of temporomandibular dysfunction and in patients with loss of teeth. Intra examiner and inter examiner reliability was high indicating a good reliability in assessing the condylar changes using panoramic radiograph.
Highlights
temporomandibular joint (TMJ) has many anatomic and functional features that make it unique and complex among the joints of the human body [1, 2]

The prevalence of radiographic changes in the condylar morphology was found to be relatively lower in Group A (Table 1)
Summary
TMJ has many anatomic and functional features that make it unique and complex among the joints of the human body [1, 2]. Condylar remodeling is a physiologic process that aims to adapt the structure of the temporomandibular joint (TMJ) to meet the functional demands. It is based on an interaction between the mechanical forces sustained by the TMJ and the adaptative capacities of the condyle. Structural changes are thought to be related to TMJ dysfunction, the mechanism of these structural changes affected by such reactive processes as remodeling, aging, and osteoarthrosis, still has not been completely clarified [4]. Temporomandibular disorders (TMD) constitute a complex set of specific entities with a wide range of reported prevalence
