ABSTRACT:
Padding for a radiographic film packet may be formed of a foamed ethylene vinyl acetate and supplied as a portion of the film packet or as a pad for attachment to an existing film packet. The pad extends along an edge surface on the film packet to relieve discomfort and to facilitate positioning of the pad and film packet within the patient's mouth for accurate exposure to X-rays. The side of the packet opposite the pad is allowed to remain unpadded for the following reasons; to avoid increasing the overall packet dimensions, to facilitate relatively free access to the film contents of the packet, and to enable the film packet to fit into film holders that are currently used for film placement. The padded film packet is especially useful in periapical films where it is especially desirable to expose root areas and adjacent tissues.
