In a clinical trial, a slow rare earth screen/film system (Siemens Titan 2D/Kodak XG) was used to obtain intraoral radiographs at conventional monitoring stages in endodontic treatment. The screen film image proved to be an effective substitute for the direct-exposure Ultraspeed periapical film. The intraoral cassettes, designed and fabricated for the study, were an adaptation of the flexible, vacuum-sealed cassettes used in mammography. It is believed that when a practicable periapical cassette is manufactured, many additional indications for the system are probable. Major reductions in patient exposure of at least 85% to 90% per periapical film would be effected.
在一项临床试验中，使用了一种慢速稀土增感屏/胶片系统（西门子Titan 2D/柯达XG）在牙髓治疗的常规监测阶段获取口腔内X光片。增感屏胶片图像被证明是直接曝光的超高速根尖片的有效替代品。为该研究设计和制作的口腔内暗盒是对乳腺摄影中使用的柔性真空密封暗盒的一种改进。据信，当制造出实用的根尖暗盒时，该系统可能会有许多其他应用。每张根尖片可使患者的辐射暴露大幅减少至少85%至90%。
