To the Editor: We have several concerns about
the study by Dr Hujoel and colleagues.1 First,
their estimates of thyroid radiation doses from panoramic and bitewing imaging
are 3 to 5 times higher than published estimates for these procedures.2,3 We believe that the authors similarly
overestimated the cephalometric dosage by as much as an order of magnitude.4,5
