“…This may be related to the original formulation of speed group E film by Eastman Kodak. Although the diagnostic accuracy of the original E-speed film, Ektaspeed ® , was comparable to D-speed film, the image was grainier, had greater fog density and lower film contrast, [3][4][5][6][28][29][30] and suffered more variability in quality with fluctuations in processing conditions. 31 As a result, many dentists subjectively preferred the slower D-speed film.…”

“…Eastman Kodak changed the physical properties of Ektaspeed in 1994 and renamed it Ektaspeed Plus ® , a film with contrast, sharpness, and processing characteristics comparable to D-speed film. [3][4][5][6][7] It is therefore possible that many dentists in practice less than fifteen years are more likely to have used E-speed film as students and may be familiar only with the improved film, leading to fewer reservations about using it.…”

“…The use of E-speed film [1][2][3][4][5][6][7][8] and the recently introduced film in speed group F 9-11 permits significant exposure reductions compared to the slower D-speed film.

“…T echnical advances in x-ray equipment and imaging systems have allowed significant reductions in radiation doses to patients during intra-and extraoral radiography. The use of E-speed film [1][2][3][4][5][6][7][8] and the recently introduced film in speed group F 9-11 permits significant exposure reductions compared to the slower D-speed film. Rectangular collimation of the x-ray beam decreases the amount of tissue exposed, thereby lowering the absorbed dose to the patient.…”

Objectives: The aim of this study was to compare the properties of the DFL Contrast FV-58 F-speed film (DFL Co., Rio de Janerio, Brazil) with the Kodak Insight E/F speed film (Eastman Kodak, Rochester, NY) in fresh and exhausted processing solutions. The parameters studied were the speed, average gradient and latitude. Methods: Five samples of each type of film were exposed under standardized conditions over 5 weeks. The films were developed in fresh and progressively exhausted processing solutions. Characteristic curves were constructed from values of optical density and radiation dose and were used to calculate the parameters. An analysis of variance was performed separately for film type and time. Results: DFL Contrast FV-58 film has a speed and average gradient that is significantly higher than Insight film, whereas the values of latitude are lower. Exhausted processing solutions were not significant in the parameters studied. Conclusion: DFL Contrast FV-58 film has stable properties when exhausted manual processing solutions are used and can be recommended for use in dental practice, contributing to dose reduction.

The Use of Radiation Dose‐Reduction Techniques in the Practices of Dental Faculty Members

X‐ray exposure to dental patients has been significantly reduced by the introduction of speed group E intraoral film, rectangular beam limitation, long position indicating devices (PIDs), and rare‐earth intensifying screens for extraoral radiography. Research indicates that many dentists do not use these techniques. However, schools of dentistry have implemented them to varying degrees for many years, so this investigation was conducted to determine the extent to which dental school faculty members use these materials and techniques in their own practices. Comparisons were made between full‐ and part‐time instructors, those in practice for fifteen years or less and those in practice for more than fifteen years, and those with postgraduate education versus those with no formal education beyond dental school. The significance of differences was measured with chi‐square analysis. The results indicate that dentists with faculty appointments utilize dose‐reducing techniques to degrees that are comparable to or greater than reported usage by nondental faculty practitioners. Faculty dentists in practice fifteen years or less are more likely than their older colleagues to use E‐speed film (p = 0.001), whereas those in practice more than fifteen years are more likely to use longer PIDs (p = 0.049). Greater acceptance of these practices by faculty may lead to reinforcement of their use in the clinical education of dental students.
