American Dental Association Statement on ‘Ante Partum Dental Radiography and Infant Low Birth Weight’ (JAMA, April 28, 2004)

Recently published research associating pregnant women’s exposure to dental X-rays with low-weight births reinforces the importance of the American Dental Association’s long-standing recommendation that, in addition to abdominal shielding (e.g., protective aprons), dentists should use thyroid collars on all patients whenever practical to minimize radiation exposure. ADA recommendations for using leaded aprons and collars were first published in 1989 and reinforced in updated guidelines in 2001.*

The American Dental Association recommends that pregnant women postpone elective dental X-rays until after delivery; however, there are times when an X-ray may be required during pregnancy to help dentists diagnose and treat oral disease.

Maintaining good oral health during pregnancy can be critical to the overall health of both expectant mothers and their babies. As such, pregnant women should continue to see a dentist regularly for oral exams and professional teeth cleanings. Left untreated, some maternal oral problems can potentially threaten the health of unborn children. For example, studies have shown that pregnant women with severe gum disease may be at increased risk for preterm delivery. Preliminary follow up studies have shown professional oral health care administered during pregnancy to this at-risk group actually improved pregnancy outcomes.

Women should inform their dentists if they are pregnant, might be pregnant or plan to become pregnant. Should dental X-rays be required during pregnancy, the American Dental Association recommends that a protective thyroid collar and apron be used, unless specific clinical conditions indicate otherwise.
