NOCTI Dental Assisting Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What is likely to happen if there is excessive vertical angulation during an x-ray?

Overlapping

Foreshortening

Excessive vertical angulation during an x-ray procedure can lead to foreshortening of the image. This occurs because the angle at which the x-ray beam is directed can distort the representation of the teeth or structures being imaged. When the vertical angulation is increased too much, the teeth appear shorter than they actually are, as the image does not capture the full length of the object.

In contrast, optimal vertical angulation allows for a more accurate representation of the anatomical structures, providing a clearer and more diagnostic image. Understanding the significance of the proper angulation is crucial for dental assistants, as it directly affects the quality of diagnostic images, ultimately influencing patient care.
