Question

Quizplus · Accepted Answer

Centering the film over the area to be examined is crucial for obtaining accurate images. Placing the film vertically or having the tabbed side facing the teeth is not a universal guideline, as different positioning techniques may require different orientations. While positioning the identification dot to the distal is commonly followed, it is not always necessary or possible depending on the tooth being examined.
