【摘要】：目的:对比分析下颌神经管在CBCT与曲面体层片上可见性的一致性,探讨影响下颌神经管在图像上可见性的非病变因素。方法:选取2013年12月~2014年2月期间在华西口腔医院同时拍摄了CBCT与曲面体层片的患者92例,由2位放射科医师同时观察患者的CBCT片与曲面体层片。把CBCT及曲面体层片上的下颌神经管从颏孔至下颌升支前缘处平分为1、2、3三个区域,分为0、1、2、3四个等级的分对下颌神经管的可见性进行评分。结果:2位医师间的内部一致性检验符合标准。CBCT上,区域1平均得分为2.120,区域2为2.337,区域3为2.533;曲面体层片上,区域1平均得分为1.772,区域2为1.973,区域3为2.207。越往后区域可见性越高。结论:CBCT对下颌神经管的可见性显著高于曲面体层片,仅有1%的下颌神经管在曲面体层片上可见,在CBCT上不可见。下颌神经管的可见性与年龄呈相关性,年龄越大,可见性越低。
[Abstract]:Objective: to compare and analyze the consistency of the mandibular canal visibility between CBCT and curved lamina. To investigate the non-pathological factors affecting the visibility of mandibular nerve tube on image methods: 92 cases of CBCT and curved film were taken simultaneously from December 2013 to February 2014 in Huaxi Oral Hospital. Two radiologists observed the CBCT film and the curved slice at the same time. The CBCT and the mandibular nerve canal on the curved slice were divided into 3 regions from the mental foramen to the anterior edge of the mandibular ascending branch. Results the internal consistency test between the two doctors was consistent with the standard. CBCT showed that the mean score of area 1 was 2.120, area 2 was 2.337, area 3 was 2.5333.On the surface of the body, the internal consistency of the mandibular canal was evaluated. The average score of region 1 was 1.772, that of region 2 was 1.973, and that of region 3 was 2.207.Conclusion the visibility of mandibular nerve canal was significantly higher than that of curved slice, and only 1% of the mandibular nerve tubes were visible on curved slice. It was not seen on CBCT. The visibility of mandibular canal was correlated with age. The older the age, the lower the visibility.
