What is the effect of overexposure on a radiograph?

Overexposure on a radiograph results in an image that appears too dark. This occurs because excessive radiation exposure increases the density of the image, causing the areas that normally would have been lighter to register as darker on the film or digital sensor. As a result, important details, which may typically show up in lighter areas, can become obscured or lost.

Understanding overexposure is crucial for producing high-quality images in dental radiography. Correctly managing exposure levels ensures that diagnostic features are visible and that the radiograph accurately reflects the anatomical structures being examined.
