There was no significant difference once the lesion was in cortical bone. Several studies in the past 2 years have addressed the question of radiolucencies. This refers to the number of lines of pixels. A radiograph with a wide dynamic range uses all 256 shades of gray. A well-balanced radiograph is evenly distributed among those shades.
Image files are very large.
Color image files are larger because they use 24 bits, or more, to define a pixel. This allows millions of colors. Image files for digital intraoral radiographs are generally 400-500 Kbytes, but they will get bigger as the resolution of the sensors improve in future systems. Printers Printing out the digital radiograph is usually done on thermal imaging paper. This paper, unfortunately, is not archiveable because the image fades within months.
