The presence or absence of an area of periapical pathosis as exemplified by an area of rarefaction in 260 cases selected at random was determined by viewing a single radiograph of each case using three viewing techniques. Six examiners viewed the radiographs independently. They agreed with one another about 50% of the time. Holding the radiograph up to the view box was found to be more accurate than either projecting the image on a screen or viewing the radiograph through a magnifier viewer. By using the three techniques, individual examiners were able to agree with themselves an average of 68.8% of the time.
