Question

Quizplus · Accepted Answer

The position of the PID (position indicating device) is important in obtaining accurate dental radiographs. The open end of the PID should be placed as close as possible to the patient's face without touching it, and its midpoint should be centered over the area of interest before the exposure is made. This helps to minimize distortion and ensure optimal image quality.
