| 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. |

| #1) 26313308 | Kelaranta/2015 | One anthropomorphic female phantom | Laboratory study | | Key results | Key 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. |
