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.
本研究旨在评估髁突形态的影像学改变的患病率及其与年龄、颞下颌关节紊乱病的临床体征和症状以及牙列状况的关系，同时评估使用全景X线片评估髁突变化时检查者内和检查者间的可靠性。本研究共招募了75名受试者。他们被分为3个年龄组。20 - 40岁（A组）、41 - 60岁（B组）和61岁及以上（C组）。每个年龄组的25名受试者均接受了临床和影像学评估。髁突形态的影像学改变和颞下颌关节紊乱病症状的患病率分别为81.3%和18.6%。下颌髁突形态的影像学异常随年龄增加。在有颞下颌关节紊乱病临床体征和症状的患者以及牙齿缺失的患者中更常见。检查者内和检查者间的可靠性较高，表明使用全景X线片评估髁突变化具有良好的可靠性。
