RE: Dental X-Rays Might Lead to Small Babies
Of course, one could ask if the thyroid function of
the women with low birth weight babies checked? To
the best of my knowledge, the thyroid function is not
a routine test given to pregnant women.
A few years ago, there was a concern about children
born along the Rio Grande River having a high incident
of spina bifida. The cause was low amounts of folic
acid in the women's diet.
I suspect that there is a casual vs. casual
relationship between dental x-rays and low birth
weight babies.
