The purpose of this study was to compare E-speed film, CDR, and modified CDR
images by means of observing some artificial defects of alveolar bone wall in the sound
human dried mandibles. High diagnostic accuracy was shown in 1 wall ailed 4 wall
defects by all 5 observers (2 Radiologists, 2 Periodontists, 1 General practitioner), but
the diagnosis in 2 wall and 3 wall defects was inaccurate. Modified CDR images had
the more diagnostic accuracy than E-speed aim and CDR image, but there was no
statistical difference among them. Finally, radiologist used modified CDR images more
than others and used equalization effect more than the change in contrast and/or
brightness.
