To the Editor: Dr Hujoel and colleagues1 did not control for the number of dental caries
or other dental pathology. It is possible that women with more dental disease
or dental disease of greater severity are more likely to have LBW infants
than those with healthy teeth. Additionally, in their study radiation dose
from dental radiographs was related to maternal smoking and late prenatal
care. It is possible that this is a more important correlation than dental
radiography and LBW.
