摘　　要：目的 探讨数字胃肠在颞下颌关节紊乱综合症的临床诊断中的价值.方法 对30例颞下颌关节紊乱症患者数字胃肠下连续采集张闭口位全程影像,通过图像后处理,测量关节间隙并观察髁状突运动轨迹,作出诊断（将该方法简称为新方法）,并与常规许勒氏位（传统法）对比.结果 数字胃肠透视下定位采集图像可清晰显示关节间隙及髁状突运动轨迹,通过成像后处理获得最佳诊断图像,其显示颞下颌关节的异常改变的能力明显优于传统法,两者差异具有统计学意义（F=7.54,P〈0.05）.结论 新方法一次定位可获得满意图像,提高了诊断效率.Objective To investigate the value of digital gastrointestinal graphy on clinical diagnosis of temporomandibular joint disorder. Methods Thirty patients with temporomandibular disorder were continuous photographed by digital gastrointestinal graphy in course of mouth opening and closing movement（this method,a new method for short）,then contrast with normal Schullers＇ X-ray photograph position（the traditional method）. Results The image collected by digital gastrointestinal graphy can clearly display the joint space and motion trail of mandibular condyle,and the best image can be achieved by reprocessing.The display of the temporomandibular joint abnormal change is significantly better than traditional method,both have statistically significant differences（F=7.54,P〈0.05）. Conclusion The new method can achieve satisfactory image with onetime positioning and increase the diagnosis effficiency.It is convenient and quick compared with nomal Schullers＇ X-ray photograph position.
