Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A resilient pad for attachment to a dental radiographic film packet having a thickness dimension defined by opposed lingual and labial surfaces, said surfaces being joined together along longitudinal side edges and along transverse end edges, the pad comprising: an elongated foldable pad body formed of a resilient non-toxic material, biocompatible with oral tissues and including a length dimension between ends, a width dimension between pad side edges, and a thickness dimension between inner and outer pad surfaces; wherein the length dimension of the pad body is at least equal to the length of the end edge of the film packet and the width dimension is greater than the thickness dimension of the film packet; an adhesive along the inner surface for attaching the foldable pad body to the film packet along an edge thereof and with the inner surface overlapping adjacent portions of the lingual and labial film packet surfaces.
Claim 2
Dependent Claim
151 words
A resilient pad for attachment to a dental radiographic film packet having a thickness dimension defined by opposed lingual and labial surfaces, said surfaces being joined together along longitudinal side edges and along transverse end edges, the pad comprising: an elongated foldable pad body formed of a resilient non-toxic material, biocompatible with oral tissues and including a length dimension between ends, a width dimension between pad side edges, and a thickness dimension between inner and outer pad surfaces; wherein the length dimension of the pad body is at least equal to the length of the end edge of the film packet and the width dimension is greater than the thickness dimension of the film packet; an adhesive along the inner surface for attaching the foldable pad body to the film packet along an edge thereof and with the inner surface overlapping adjacent portions of the lingual and labial film packet surfaces.
Claim 3
Dependent Claim
25 words
The resilient pad of claim 1 wherein there are two pad ends and side edges and wherein the two pad side edges are substantially parallel.
Claim 4
Dependent Claim
35 words
The resilient pad of claim 2 wherein the length dimension of the pad between the remaining pad end and notches is at least equal to the length of an end edge of the film packet.
Claim 5
Dependent Claim
17 words
The resilient pad of claim 1 wherein the pad body is formed of foamed ethylene vinyl acetate.
Claim 6
Dependent Claim
18 words
The resilient pad of claim 1 wherein the pad body includes a thickness dimension of approximately 1.5 mm.
Claim 7
Dependent Claim
58 words
The resilient pad of claim 1 wherein the pad body is substantially rectangular, having substantially parallel paired sides and ends and wherein each side includes a notch formed adjacent each end and wherein the length dimension between the notches on each side is at least equal to the length dimension of one of the film packet end edges.
Claim 8
Dependent Claim
19 words
The resilient pad of claim 6 wherein the notches are aligned across the pad body adjacent the ends thereof.
Claim 9
Dependent Claim
31 words
The resilient pad of claim 1 further comprising a longitudinal depression formed along the inner surface and extending longitudinally between the pad ends for receiving an edge of the film packet.
