青少年上颌Wilson曲线与颞下颌关节紊乱病的相关性研究

Clinical Research on Relationship between Wilson Curve and Temporomandibular Joint Disorders in Teenagers

目的:研究青少年上颌Wilson曲线与颞下颌关节紊乱病(temporomandibular joint disorders,TMD)症状之间的关系。方法:选取2017年1~7月的就诊于新疆医科大学第一附属医院青少年患者及自愿参加本研究的大学生105名。根据TMD诊断标准把研究对象分为TMD组与正常对照组,并对研究对象进行肌肉疼痛与关节弹响症状进行检查,并通过CBCT测量Wilson曲线的角度,结果采用单因素方差分析与t检验进行统计分析。结果:TMD组与正常对照组Wilson曲线的角度相比较,差异具有统计学意义,TMD组Wilson曲线的平均角度较大。有关节弹响症状的患者弹响关节同侧的磨牙颊舌向轴倾度大于非弹响侧磨牙的颊舌向轴倾度,差异有统计学意义。弹响关节对侧非弹响的磨牙颊舌向倾斜度与正常组相比,差异无统计学意义。有肌肉弹响、无肌肉疼痛的患者Wilson曲线的角度相比较,差异无统计学意义。结论:TMD患者较正常对照组呈现更深的Wilson曲线。弹响侧的磨牙颊舌向倾斜角度大于非弹响侧。较深的Wilson曲线会导致TMD患病风险增加。而TMD肌肉疼痛症状与Wilson曲线的角度并无明显相关性。

Objective： To investigate the relationship between the angle of curve of Wilson （COW） and tem- poromandibular joint disorders （TMD） in teenagers. Methods： A total of 105 undergraduates who volunteered and teenage patients with TMD visiting the First Affiliated Hospital of Xinjiang Medical University from January to July 2017 were recruited in the study. The subjects were divided into the TMD group and the normal control group ac- cording to the diagnostic criteria of TMD, and the subjects were examined for the symptoms of muscle pain and sounds of the temporomandibular joint （TMJ）. The angle of curve of Wilson was measured by CBCT. Related data were analyzed statistically with one--way analysis of variance and t--test. Results： The difference was statistically significant between the COW of TMD group and the normal control. The average angle of COW in TMD group was greater. The angle of molar buccal lingual inclination at the side with TMJ sounds was significantly larger than that of the opposite side without sounds; while contralateral the angle of molar buccal lingual inclination of patients with TMJ sounds had no significant differences with those of normal groups. There was no statistically significant differ- ence in the COW between the patients with and without muscle pain. Conclusion： TMD patients showed a deeper COW than normal controls. The angle of molar buceal lingual inclination at the side with TMJ sounds was signifi- cantly larger than the opposite side without sounds. A larger COW causes an increased risk of TMD disease. The TMD muscle pain symptoms were no significantly related to the COW.
