Which practice best supports ALARA in dental radiography?

ALARA in dental radiography means getting the diagnostic information you need with the smallest possible radiation dose. The best way to do this is to combine proper prescribing (only imaging when truly needed), tight collimation to limit the beam to the area of interest, using fast receptors (so less exposure is needed for a diagnostic image), and applying the correct exposure technique (appropriate kVp, mA, and exposure time). These practices work together to minimize dose while preserving image quality. Choices like increasing kVp beyond recommended, using longer exposure times, or exposing with a larger beam field would either raise the dose, degrade image quality, or necessitate retakes, which undermines ALARA.
