How do exposure times for digital radiography compare to those needed for conventional radiography?

In digital radiography, exposure times are significantly shorter than those used in conventional radiography. This reduction in exposure time—ranging from 50% to 80% less—is largely due to the enhanced sensitivity of digital sensors to radiation. Unlike conventional film, which requires more radiation to produce a viable image, digital sensors can capture the necessary information with much lower doses. This capability allows for greater efficiency in the imaging process and minimizes the radiation exposure to both patients and practitioners.

Additionally, digital radiography employs advanced image processing techniques, which enables the enhancement of images that may not have been ideal at the point of exposure, further reinforcing the practice's emphasis on lower exposure times. Consequently, the substantial decrease in exposure times not only improves patient safety but also streamlines the workflow in dental settings, making digital radiography a preferred choice in modern dental practices.
