Digitally Scanned Radiographs versus Conventional Films for Determining Clarity of Periapical Lesions and Quality of Root Canal Treatment

Note. When the evaluator determined that the digital image showed greater detail than the radiograph a “+” was scored, if they were equal a “=” was scored, and if the detail was less a “−” was scored.
