| ［摘要］ 目的 探讨数字化融合体层（DTS）摄影在颞下颌关节摄影技术中的临床应用价值。方法 将60例可疑颞下颌关节功能紊乱患者随机分为两组各30例，对照组用颞下颌关节侧位DR摄影技术，实验组用颞下颌关节数字化融合体层摄影技术，对双侧颞下颌关节进行开、闭口摄影，各共取120幅图像。由一位副主任医师和一位副主任技师，分别观察DR图像和DTS图像，评价两种成像技术所获得的图像质量和下颌骨关节面形态结构与移动情况。结果 实验组图像优于对照组，差异有统计学意义（P<0.05）。结论 用颞下颌关节数字化融合体层摄影技术显示颞下颌关节形态结构与移动情况明显优于颞下颌关节侧位DR摄影技术，是颞下颌关节摄影的首选技术。 |

| Abstract: |
| ［Abstract］ Objective To evaluate the clinical application value of digital fusion tomography(DTS) in the temporomandibular joint photographic technology.Methods 60 patients with suspected temporomandibular joint dysfunction were randomly divided into two groups, with 30 cases in each group. The control group received temporomandibular joint and lateral digital radiography(DR) photography and the experimental group received temporal mandibular joint digital tomography. 120 images were taken from the open photography and the closed photography of bilateral temporomandibular joints respectively. The DR images and DTS images were observed by an associate chief physician and an associate chief technologist respectively. The image quality was obtained from the two imaging techniques and the articular surface morphology and activity of the mandible were evaluated.Results The quality of images in the experimental group was better than that in the control group(P<0.05).Conclusion DTS is the better photographic technique than DR photography to show the temporomandibular joint morphology, structure and activity. |
