Priority Practice-level Dose Reduction Recommendations

There are many ways to minimize radiation exposure to dental patients. First and foremost are fundamental priority concepts that, when incorporated into dental imaging practices, will serve to minimize exposure to dental patients and reduce risk. The priority radiation dose reduction measures are outlined in Table 1.

Table 1. Priority Practice-level Dose Reduction Recommendation.2

  1. Familiarity and compliance with applicable local, state, and federal laws.
  2. Prescription of radiographs based on diagnostic and treatment planning needs, and a good-faith effort by the dentist to acquire prior dental imaging examinations.
  3. Utilization of digital receptors in lieu of film for intraoral, panoramic, and cephalometric imaging.
  4. Use of rectangular collimation for intraoral imaging whenever possible.
  5. Utilization of CBCT only when lower-dose options will not yield the necessary diagnostic information.
