What effect does improper vertical angulation have on radiographs?

Improper vertical angulation can lead to elongation in radiographs, which occurs when the x-ray beam is angled incorrectly relative to the film or sensor. When the beam is angled too far in the vertical direction, the resulting image of the object appears longer than its actual size. This distortion arises because the relationship between the x-ray source and the anatomical structures being imaged is altered, affecting how those structures are projected onto the image receptor.

In contrast, proper angulation would ensure that images reflect the true size and shape of the anatomical structures, making it critical for accurate diagnosis and treatment planning in dentistry. Understanding the correct vertical angulation and its effects is vital for producing high-quality radiographs that facilitate effective patient care.
