The relationship between radiographic changes and clinical signs and symptoms of the temporomandibular joint (TMJ) was investigated in 39 patients with joint diseases. Radiographic erosions were found in 33% of the TMJ joints, and overall frequency of radiographic changes including remodeling was 47%. Fifty-four percent of the patients had an anterior open bite (AOB). The AOB showed statistically significant correlation to the extension of erosion of the TMJ. Pain expressed by means of a visual analog scale, tenderness to palpation of the TMJ, and pressure pain threshold showed no significant correlation to erosion, but mandibular mobility showed significant negative correlation to erosive changes. In conclusion, AOB is correlated with erosive radiographic changes in this patient group. However, the degree of local pain and tenderness showed no correlation to radiographic changes.
对39例关节疾病患者的颞下颌关节（TMJ）影像学改变与临床体征和症状之间的关系进行了研究。在33%的TMJ关节中发现了影像学侵蚀，包括重塑在内的影像学改变的总体发生率为47%。54%的患者存在前牙开颌（AOB）。AOB与TMJ侵蚀范围呈统计学显著相关。通过视觉模拟量表表达的疼痛、TMJ触压痛和压力痛阈值与侵蚀无显著相关性，但下颌运动度与侵蚀性改变呈显著负相关。总之，在该患者组中，AOB与侵蚀性影像学改变相关。然而，局部疼痛和压痛程度与影像学改变无关。
