目的分析中老年患者Spee曲线深度特点与颞下颌关节紊乱病(temporomandibular joint disorders,TMD)症状之间的关系。方法采用随机数字表法从2013年1—7月于中国医科大学附属口腔医院就诊的中老年TMD患者中选取89例,根据TMD研究诊断标准对患者肌肉疼痛与关节弹响症状进行检查,并通过研究模型测量患者Spee曲线深度。比较无肌肉疼痛及各级肌肉疼痛症状患者Spee曲线平均深度以及有无关节弹响症状患者的两侧Spee曲线深度,分别采用单因素方差分析与t检验进行统计分析。结果有关节弹响症状患者的弹响关节同侧Spee曲线深度小于无关节弹响患者该侧Spee曲线深度,差异有统计学意义(左侧:P<0.001;右侧:P=0.008);而弹响关节对侧Spee曲线深度与无弹响患者相比,差异无统计学意义(左侧:P=0.481;右侧:P=0.905)。无肌肉疼痛及轻、中、重度肌肉疼痛症状的患者Spee曲线平均深度相比较,差异均无统计学意义(P=0.327)。结论TMD关节弹响症状与Spee曲线关系密切,伴有关节弹响的TMD患者的弹响关节同侧Spee曲线深度较小,形态较为平坦。而TMD肌肉疼痛症状与Spee曲线的深度并无明显相关性。
Objective To analyze the relationship between the depth of Spee curve and the symptoms of temporomandibular joint disorders (TMD) in middle-aged and elderly patients. Methods Totally 89 middle-aged and old-aged patients with TMD were selected from the Stomatological Hospital of China Medical University from January to July in 2013 by random number table. According to TMD diagnostic criteria, the symptoms of muscle pain and joint soreness were examined and passed The study model measures the patient’s Spee curve depth. The mean depth of Spee curve and the Spee curve depth on both sides of patients with no muscular pain and muscle pain symptoms at all levels were compared and analyzed by one-way ANOVA and t-test. Results The stenosis of ipsilateral Spee curve in patients with sachet symptoms was smaller than that in patients without achondroplasia (left: P <0.001; right: P = 0.008); while There was no significant difference in squeal Speen curve between snapping joints and non-snapping patients (left: P = 0.481; right: P = 0.905). There were no significant differences in mean Spee curve depth between patients with no muscular pain and those with mild, moderate or severe muscular pain (P = 0.327). Conclusions TMD stenosis symptoms are closely related to Spee curve. TMD patients with snapping TME have the same ipsilateral Spee curve with smaller depth and shape. There was no significant correlation between TMD muscular pain symptoms and the depth of Spee curve.
