Title In Pregnant Women, Diagnostic Dental Radiation Does Not Increase the Incidence of Congenital Anomalies
Clinical Question In pregnant women, does diagnostic dental radiation increase the incidence of congenital anomalies?
Clinical Bottom Line Based on this laboratory study, the exposure dose during dental radiography is far lower than the dose needed to cause anomalies in fetus.

Key resultsKey Results: The results of the study estimated the fetal doses at 0.009 to 6.9  μGy, and the breast doses at 0.602 to 75.4 μGy; with lead shields, these doses are less (fetal doses 0.005-2.1  μ Gy, and breast doses 0.002-10.4  μGy). Accordingly, the fetal dose levels without lead shielding were less than 1% of the annual dose limit, which is 1  mSv for a member of the public. In intraoral, panoramic, and cephalometric examinations without lead shields the fetal doses reached 0.1%-10% of the maximum fetal doses in CBCT.

Comments on
The Evidence
Validity: This was a laboratory dosimetry study, a valuable addition to the literature as it addressed a range of current dental radiographic exposures. Although there have been population-based human studies on diagnostic radiology-related cancer induction, no population-based human studies have been published on fetal effects from dental diagnostic radiography.
Applicability Although this was a pre-clinical, i.e. laboratory, study, the fetal doses measured were greatly below the threshold dose known, from other studies, to induce fetal abnormalities.
