An additional advantage of direct digital radiography is being able to immediately adjust the positioning of an image, or to adjust the amount of exposure.

 For images through the maxilla, of apical regions, or extraoral views, higher exposure times might be necessary to get sufficient clarity.

 For images through thinner bone, or to accurately assess the extent of periodontal bone loss, shorter exposure times might be necessary (Figure 3.27).

 The Sopix digital dental sensor has the widest latitude of exposure, minimizing the need for exposure adjustments [4].

Figure 3.27 (a) Radiograph of right maxillary fourth premolar and first molar shows apparent significant periodontal bone loss, but crown density is also light, an indication of possible overexposure. (b) Repeat radiograph of maxillary premolar with decreased exposure shows moderate bone loss, a more accurate assessment. The Sopix sensor often accommodates to account for exposure issues.
