概要

As ICRP Publication 16 recommends, the roentgenography should be carried out in exposure to the patient as low as practical. With this respect, in order to reduce the patient dose, dental roentgenography with the intensifying screen was tried. With preliminary experiment it was concluded that the existing screens would be useless for dental roentgenography, because of its great lack of sharpness in image. New intensifying screen (Kyokko BF) which was manufactured with trial by Dainippon Toryo Co., Ltd. would substitute as the non-screen film dental roentgenography when the sharpness of the image is not stirictly required. When BF screen is applied to dental roentgenography exposure is about 80% less as compared with that in the case of non-screen dental roentgenography. The authors acknowledge Professor Dr, Toru Oka, Department of Oral Surgery, Nagoya University school of Medicine, for his kind advice to this research work.
