The clinical findings in 20 patients with TMJ-crepitation (E1-group) and 19 patients with TMJ palpatory tenderness (E2-group) have been compared with the findings in 29 other patients with mandibular dysfunction (R-group). The patients underwent a clinical examination of the masticatory system and of the second distal interphalangeal joints (DIP II joints). No statistically significant differences could be found between groups with respect to clinical signs, occlusal interferences, or dental attrition. Loss of molar support was found to be significantly more frequent in the E1-group than in the R-group. The frequency of tenderness to palpation or pain on movement of DIP II joints was significantly higher in the E2-group than in the R-group. Periarticular bony swelling of DIP II joints was significantly correlated with TMJ-crepitation. The patients with TMJ-crepitation were considered to have TMJ-osteoarthrosis. The results of the present study indicate that patients with TMJ-OZ have a similar clinical picture to other patients with mandibular dysfunction and that molar loss plays a role in the etiology of TMJ-OA.
对20例颞下颌关节弹响患者（E1组）和19例颞下颌关节触压痛患者（E2组）的临床检查结果，与另外29例下颌功能紊乱患者（R组）的检查结果进行了比较。这些患者均接受了咀嚼系统及第二远端指间关节（DIP II关节）的临床检查。在临床体征、咬合干扰或牙齿磨耗方面，各组之间未发现统计学上的显著差异。结果发现，E1组磨牙支持丧失的发生率显著高于R组。E2组DIP II关节触压痛或活动时疼痛的发生率显著高于R组。DIP II关节的关节周围骨质肿胀与颞下颌关节弹响显著相关。有颞下颌关节弹响的患者被认为患有颞下颌关节骨关节炎。本研究结果表明，颞下颌关节骨关节炎患者与其他下颌功能紊乱患者具有相似的临床表现，且磨牙缺失在颞下颌关节骨关节炎的病因中起作用。
