What is the likely cause of cone cutting in radiography?

Cone cutting in radiography is primarily caused by the central ray not being aimed at the center of the film. When the x-ray beam is misaligned and does not strike the center of the film or sensor, it creates a partially exposed film where an area remains unexposed. This results in a noticeable white portion on the radiograph that resembles a cut or missing segment, hence the term "cone cutting."

Aiming the central ray accurately at the film's center is crucial for obtaining a complete and diagnostic image. It ensures that the entire area of interest is adequately exposed to radiation, thus producing a clear and usable diagnostic image. Proper alignment helps to avoid artifacts such as cone cutting, which can hinder the assessment and interpretation of dental conditions.

Understanding the mechanics of proper film positioning and alignment is essential for anyone involved in radiography to reduce the incidence of such errors.
