What is the result of excessive vertical angulation during radiographic imaging?

Excessive vertical angulation during radiographic imaging results in foreshortening of the image. When the vertical angulation is too steep, the teeth appear shorter than their actual size. This occurs because the x-ray beam is directed at an angle that does not accurately project the length of the teeth onto the film or digital sensor.

In an optimal scenario, the angulation should be positioned to allow the x-rays to hit the teeth perpendicularly, which helps in capturing their true height and shape. However, when the angle becomes too pronounced, the image distorts, leading to a foreshortened representation. Understanding this principle is crucial in ensuring accurate diagnostic images in dental practice, as it directly impacts the interpretation and subsequent treatment decisions.
