Abstract

Kodak's Ektaspeed (E) dental film is twice as fast as Ultraspeed (D) film and thereby significantly reduces radiation exposure to the patient. The film quality of the E film and D film was compared following processing with two manual and two automatic processing techniques. E-speed film processed manually or automatically produces diagnostically acceptable radiographs, with film densities within the recommended density limits commonly used in dentistry. High-contrast and low-contrast radiographs can be achieved by varying processing techniques.

摘要

柯达的超高速（E型）牙科胶片的感光度是超高速（D型）胶片的两倍，从而显著减少了患者所受的辐射量。在用两种手动和两种自动冲洗技术冲洗后，对E型胶片和D型胶片的质量进行了比较。手动或自动冲洗的E速胶片都能产生诊断上可接受的X光片，其胶片密度在牙科常用的推荐密度范围内。通过改变冲洗技术可以获得高对比度和低对比度的X光片。
