Abstract
Eastman Kodak Company has developed a new E-speed dental X-ray film called Ektaspeed plus. The sensitometric properties, and information yield of this film were compared with those of other conventional direct emulsion dental X-ray films produced by Eastman Kodak, Ektaspeed EP-22 and Ultra-Speed DF-57. The contrast of Ektaspeed plus is close to that of Ultra-Speed, whilst the speed of Ektaspeed plus is similar to that of Ektaspeed. The latitude of the new film is narrower than that both Ektaspeed and Ultra-Speed.
