What happens if a receptor is placed backwards and how can it be avoided?

• A. The image may be reversed or show incorrect anatomy; prevent by checking receptor markings and ensuring proper alignment before exposure.
• B. The image may be reversed but not affected by markings.
• C. There will be no effect.
• D. The receptor will be damaged.

Answer: (A)

Placing the receptor backwards changes how the X-ray projection lands on it, so the resulting image can be reversed left-to-right and show the anatomy flipped. That mirroring can make it hard to identify which tooth or side of the mouth you’re looking at and can lead to misinterpretation of features like caries, bone levels, or root positions. To avoid this, always check the receptor markings or markers on the holder and confirm the correct orientation before exposure, ensuring the receptor is aligned with the dental arch and the marked side is in the proper position for the tooth being imaged.
