ABSTRACT:
An improved intra oral dental x-ray packet structured to both prevent x-ray radiation from passing completely through the packet into the patient's mouth and to prevent x-ray exposure of a small transverse strip at one end of the unexposed x-ray film within the packet. The unexposed portion of the x-ray film is sized so as not to significantly reduce the useful area for tooth exposure, yet providing an area for imprinting as by light exposure patient identification indicia thereonto after x-ray radiation exposure, but prior to developing the exposed x-ray film.
