Commentary on JAMA article by Hujoel et al.

A recent publication by in the April 28, 2004, issue of JAMA raises concern since it suggests that exposure to dental x rays during pregnancy could be responsible for human fetal growth retardation. Furthermore, the article could have a negative impact on the dental care of pregnant women who might fear the effect of dental radiography on their developing embryo. In our initial discussions, John Boice and I decided to communicate our concerns to the scientific and medical community. Boice has published a recent letter concerning the Hujoel paper. The Hujoel publication has very serious deficiencies. This Forum presents analyses of these deficiencies.
