What is the general guideline for intraoral radiography during pregnancy?

• A. Avoid radiographs during pregnancy unless emergency
• B. Limit radiographs to essential procedures with shielding; postpone non-urgent
• C. Take routine dental radiographs as usual
• D. Only panoramic radiographs are allowed

Answer: (B)

The key idea is to minimize fetal radiation exposure by applying the ALARA principle: only take intraoral radiographs when they are essential for patient management, shield the abdomen, and postpone non-urgent imaging during pregnancy. Radiation exposure to the fetus should be kept as low as reasonably achievable, especially since fetal tissues are more sensitive early on. Intraoral radiographs contribute a small dose, but since the pregnancy is a special situation, every effort is made to limit exposure. When imaging is necessary to diagnose a condition, plan treatment, or prevent a serious infection or complication, proceed with the minimum required exposure and use shielding (lead apron with a thyroid collar) to further reduce exposure to the abdomen. If the radiographs aren’t essential for immediate care, they should be postponed until after pregnancy. This approach is preferable to taking radiographs as a routine, which ignores the pregnancy, or restricting to only one type of radiograph or delaying everything regardless of need. It also aligns with the idea that imaging should be judicious and protective, not entirely avoided when there’s a legitimate clinical rationale.
