目的:对口腔全景曲面断层摄影和传统X线摄影进行探讨和比较,分析两者优缺点。方法:选取近年来入我院进行口腔内外摄影的被检者65例,对所有被检者进行全景曲面断层摄影及传统X线摄影,观察两种摄影结果进行比较并分析影像准确性及优缺点。结果:DR技术的甲乙级图像数量多于X线,并且其百分比高于X线,有57例被检者认为DR检查舒适度较好,只有43例被检者觉得X线舒适度良好,61例被检者对DR检查的配合度较高,只有49例被检者对X线配合度高,对两组数据进行比较与分析,其结果存在统计学差异(P<0.05)。结论:相较于传统X线摄影,全景曲面断层摄影的清晰度更高,成像更好,并且拍摄过程简单,被检者可在轻松舒适的环境下完成拍摄,且准确率更高。
OBJECTIVE: To explore and compare oral panorama tomography and traditional radiography to analyze the advantages and disadvantages of both. Methods: Sixty-five subjects who were admitted to our hospital for oral and external photography in recent years were selected. Panoramic surface tomography and conventional X-ray photography were performed on all the subjects. The results of two kinds of photography were compared and the accuracy of the images and the advantages and disadvantages were analyzed . Results: The number of Class B and Class B images in DR technique was higher than that in X-ray, and its percentage was higher than that in X. There were 57 subjects who considered DR examination as comfortable and only 43 subjects felt that X-ray comfort was good. 61 The results showed that there was a significant difference between the two groups (P <0.05). Only 49 subjects had high X-ray coordination. CONCLUSIONS: Compared with conventional X-ray photography, the panoramic surface tomography has better definition, better imaging and simple shooting process. The subjects can complete the shooting in a relaxed and comfortable environment with higher accuracy.
