A comparison of Kodak Ultraspeed and Ektaspeed Plus dental X‐ray films for use in endodontics
Australian Dental Journal, 2001AbstractBackground: The advantage of using a faster film for length determination in endodontic therapy is obvious. However, for such a film to be generally accepted, it must demonstrate comparable diagnostic quality to traditionally used films.Methods: The comparative accuracy of canal length determination of Ultraspeed and Ektaspeed Plus dental X‐ray

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

Effects of developer depletion on image quality of Kodak Insight and Ektaspeed Plus films
Dentomaxillofacial Radiology, 2004To evaluate the effect of processing solution depletion on the image quality of F-speed dental X-ray film (Insight), compared with Ektaspeed Plus.The films were exposed with a phantom and developed in manual and automatic conditions, in fresh and progressively depleted solutions.

Image-receptor performance: A comparison of Trophy RVG UI sensor and Kodak Ektaspeed Plus film
Oral Surgery Oral Medicine Oral Pathology Oral Radiology and Endodontics, 2001Objective. This study compares the physical characteristics of the RVG UI sensor (RVG) with Ektaspeed Plus film.Dose-response curves were generated for film and for each of 6 available RVG modes. An aluminum step-wedge was used to evaluate exposure latitude. Spatial resolution was assessed by using a line-pair test tool.

Base and Fog Densities of Fresh Ektaspeed Plus Dental X-Ray Films
Acta Odontologica Scandinavica, 1997Previous findings with regard to base and fog density of Ektaspeed Plus dental X-ray films have shown increased values compared with Ektaspeed and Ultra-Speed films, but the results are contradictory. The purpose of the present study was to measure base density, using 10 different fixing solutions, and fog density, using 10 different developing ...

The value of imaging modalities in enabling the observer to detect proximal dental caries has been tested previously using both natural carious cavitations and mechanical defects. This study compared the ability of dentists to detect mechanically created defects and natural dental carious cavitations on the proximal surfaces of extracted teeth, and to ...

Density versus exposure was determined for digital and film radiographic images of various thicknesses of six dental resin composites. The curves were relatively parallel; saturation at the black end of the contrast scale occurred at lower exposures with Computed Dental Radiography (CDR, Schick Industries, Long Island City, NY) than with the Sens-A-Ray
