Abstract
Using D and E speed film, intraoral exposures were made of a phantom at 70 and 90 kVp, with and without erbium filtration. Measurement of surface exposures indicates substantial reduction when erbium filtration was used. However, there was a visible loss of contrast. The raters agreed that radiographs made with E speed and D speed film, both with and without erbium filtration, were all of adequate diagnostic quality. The radiographs with the highest contrast were consistently preferred by all of the raters.
