Which principle guides decisions to minimize radiation exposure in dental imaging?

Explanation:
The central idea here is keeping radiation as low as reasonably achievable while still obtaining images that allow a proper diagnosis. This is exactly what ALARA stands for: As Low As Reasonably Achievable. In dental imaging, that means choosing exposure settings that are enough to see what’s needed, using appropriate beam collimation and shielding, applying proper technique, and selecting the most suitable method for the clinical task. Pushing for the highest resolution or the fastest exam typically requires more exposure or may compromise image quality, which would not align with minimizing dose. So ALARA is the principle that directly guides how we balance safety with diagnostic usefulness.
