Abstract
A radiographic film packet is adapted to be placed in a patient's mouth for exposing a sheet of dental film to x-rays generated by an x-ray tube. The packet includes a light-proof and moisture resistant envelope having a first side and a second side defining a pocket for receiving the film sheet. Disposed within the pocket are a sheet of lead and a sheet of film, the lead sheet being located adjacent the second side and the film sheet being located between the lead sheet and the first side. An indicator affixed to the first side expressly designates the edge of the film packet appointed to be uppermost in the mouth during radiographic exposure. A film marker is affixed to said film sheet along a periphery and proximate a corner thereof. The film marker has a constant orientation relative to the indicator, and identifies the orientation of the film sheet during exposure.
