数字X线摄影拍摄牙片图像质量分析

目的:探讨数字X线摄影(DR)拍摄牙片图像的质量及其临床应用价值。方法:利用DR设备对230例患者的260颗牙齿进行根尖片拍摄,并将拍摄结果与传统根尖片进行对比分析。结果:与传统牙齿拍片比较,DR技术拍摄牙片的曝光时间缩短,投照剂量明显减少,照片清晰度提高。结论:DR拍摄牙片技术较传统根尖片摄像技术优越,在口腔临床医学方面有着良好的应用前景。

Clinical analysis of the quality of DR-filmed tooth slice image

Objective:To explore and analyze the quality of DR-filmed tooth slice image and its value in clinical application.Methods:The periapical films of 260 teeth in 230 cases was taken by DR equipment and compared with the traditional films.Results:Compared with traditional teeth radiography technology,using DR to film the teeth outside the mouth,the exposure time was shorten,the quantity of projection was reduced,and the image definition was improved obviously.Conclusions: The DR tooth slice X-ray photography technology is superior to the traditional periapical radiography,and it has a bright prospect in clinical science of stomatology.
