Compared to film-based systems, digital radiography reduces radiation exposure by up to 80 percent. Our practice follows the ALARA principle: As Low As Reasonably Achievable. This safety principle suggests using as minimal radiation exposure as reasonable means allow. Digital radiography minimizes the risk to both the patient and operator right out of the box. Unlike film, digital images can be magnified, sharpened and enhanced for a precise diagnosis. When stored for comparison later on, the computer can highlight the areas that are different to show where changes have occurred. This feature allows both the dentist and patient to have an understanding of how the mouth is changing and identify any potential problem areas early on.
