Foreshortening of the film is primarily caused by what issue related to the PID?

too much vertical angulation
too little vertical angulation
too much horizontal angulation
too little horizontal angulation

The correct answer is: too much vertical angulation

Foreshortening of the film occurs when the vertical angulation of the X-ray tube is too extreme, meaning the tube is angled downward or upward excessively. This incorrect angulation causes the image of the teeth to appear shorter than they actually are. In the context of a periapical radiograph, proper vertical angulation is crucial; if it is too high, the image will be compressed vertically, resulting in foreshortening. This concept is fundamental in diagnostic radiography because accurate representation of the tooth structures is necessary for proper assessment and treatment planning. The other options relate to different angulation issues that could affect the quality of the radiograph, but they do not lead to foreshortening in the same way. Balanced angulation is essential for clear and precise dental imaging.
