Quizplus · Accepted Answer

The error that rendered this radiograph undiagnostic is horizontal overlapping , which resulted from not directing the x-ray beam precisely perpendicular through the teeth embrasures to the image receptor. Therefore , a shift in the horizontal angulation is the corrective action. On the radiograph, the overlap appears to get more severe in the posterior, or distal. Therefore , the corrective action is to shift the tube head so that the x -ray beam will intersect the image receptor from the distal.
