Abstract
The introduction of faster screen/film combinations allows a reduction in radiation dose but at the expense of film quality. This study investigated the accuracy of landmark location on cephalometric radiographs made using two screen/film combinations. No significant differences in reproducibility of landmark location were found. There was a 20 percent difference in the radiation dose between the two film types studied.
