Densitometric evaluation of intraoral x-ray films: Ektaspeed versus Ultraspeed.
Recently a new speed E intraoral dental x-ray film was introduced by the Eastman Kodak Company in order to reduce the radiation dose to the patient. In the present study the new higher-speed EP21 film was compared with the speed D DF58 film with regard to speed and quality (fog plus base, sharpness, resolution, and contrast) of the resulting images. Results showed no deterioration in the image with 50% dose reduction when the EP21 film was used as compared to the DF58 film. Therefore, this new type of film is highly recommended for routine radiographic examinations.
