Description

[Detailed Description of the Invention] [Field of Use of the Invention] The present invention relates to a holding sheet for a dental X-ray film package for supporting a dental X-ray film package used during dental X-ray photography.

[Conventional technology of the invention]

When taking an X-ray photograph of a tooth, the dental X-ray film package is positioned inside the tooth to be photographed (on the side with the tongue), and the X-ray is irradiated from the outside to take the photograph. . In such an X-ray photography, a dental X-ray is used.
It is necessary to hold the line film package at a predetermined position during photographing.

FIG. 2 is a partial cross-sectional view of the inside of the oral cavity when a holder for a conventional dental X-ray film package is used. In the figure, 1a, 1b
Is a tooth, 1a ₁ and 1b ₁ , is the occlusal surface of the tooth 1a and 1b, 3 is a tongue, and 4 is a cheek. 5 is a support member bitten between the teeth 1a and 1b, 6 is a dental X-ray film package adhered to the end of the support member 5, and 7 is an X-ray film sealed in the X-ray film package. Is.

The support member 5 and the X-ray film package 6 are separately prepared, and the end portion of the support member 5 is adhered to an appropriate portion of the X-ray film package 6 at the time of X-ray photography.
The tooth 1b at a position where X-ray photography can be performed, and the support member 5 is bitten by the tooth 1a and the tooth 1b, and the X-ray film package 6 is held.
Hold it in that position. Next, when the tooth 1b is irradiated with X-rays as shown by the arrow, the X-ray film 7 is exposed to X-rays of the tooth 1b.
A line image is obtained.

By the way, in the means using such a holding member, it is necessary to attach the holding member 5 to an appropriate position of the X-ray film package, which is troublesome, and in some cases, the holding member 5 cannot be used. If it is not preferable, that is, if the root end of the root of the tooth 1b is inflamed, the dentist makes a hole in the occlusal surface 1b ₁ of the tooth 1b and inserts a pulp extraction needle through this hole to the pulp. Then, the pulp is extracted, and at the same time, the pulp cavity is enlarged by a reamer or the like to reach the inflamed portion, and thereafter, the inflammation portion is treated through the enlarged pulp cavity. In the case of such treatment, it is important to know how far the tip of the extraction needle is located from the inflamed area, and in order to know this, an X-ray is taken with the extraction needle or reamer inserted. In such a case, since the teeth 1a and 1b cannot be occluded, the holding member 5 cannot be used.

In order to improve such a drawback of the holding member 5, the applicant of the present invention has proposed a means as shown in FIG. FIG. 3 is a partial cross-sectional view of the inside of the oral cavity. In the figure, the same parts as those shown in FIG. 2 are designated by the same reference numerals. Reference numeral 8 is a mucoadhesive applied to the X-ray film package 6. Mucoadhesives have a water-soluble polymer as a main component, and have been studied and put into practical use as an adhesive for adhering electrodes to a human body when, for example, creating an electrocardiogram. Since such an adhesive is mainly composed of synthetic resin and does not contain lead or the like, it has a property of transmitting X-rays. At the time of X-ray photography, the X-ray film packaging body 6 is positioned at a predetermined position, and the X-ray film packaging body 6 is pressed against the gingiva 2 as it is. Retained.

By the way, the means using this mucoadhesive must add an extra step to the manufacturing process of the X-ray film package 6,
Further, there is a problem that it cannot be used for the existing X-ray film package 6.

[Purpose of device]

The purpose of the present invention is to solve the above problems, and
Another object of the present invention is to provide a holding sheet for an X-ray film package, which is applicable to a line film package and has a simple structure.

[Outline of device]

In order to achieve the above object, the present invention provides a holding sheet for a dental X-ray film package by applying a normal adhesive on one side of the sheet and a mucosal adhesive on the other side. Is configured.

[Example of device]

 Hereinafter, the present invention will be described with reference to the illustrated embodiments.

FIG. 1 is an enlarged side view of a holding sheet of a dental X-ray film package according to an embodiment of the present invention. In the figure, 10 is a sheet of synthetic resin or paper, 11 is a normal adhesive applied to one side of the sheet 10, and 12 is the aforementioned mucoadhesive applied to the other side of the sheet 10. In order to distinguish between the adhesive 11 and the mucoadhesive 12, it is desirable to mix one of the colorants of a predetermined color, or mix both of the colorants of different colors. 13 and 14 are adhesive 11 and mucoadhesive, respectively
It is a release paper adhered on 12. 15 is the sheet 10, adhesive
11, a cut line for cutting the mucoadhesive 12 and the release papers 13, 14 into an appropriate size, for example, a width and length smaller than the X-ray film package 6, and is formed by perforations, for example.

At the time of X-ray photography, the cutting line 15 allows the sheet 10,
A small piece composed of the adhesive 11, the mucoadhesive 12, and the release papers 13 and 14 is cut out, and first, the release paper 13 is peeled off and the small piece is adhered to the X-ray film package 6 with the adhesive 11. Next, the release paper 14 is peeled off to expose the mucoadhesive 12, the X-ray film package 6 is positioned at a predetermined position in the oral cavity, and the mucoadhesive 12 is bonded to the gingiva 2 at that position. This makes X
The line film package 6 is securely held at a predetermined position, and accurate X-ray photography can be performed.

[Effect of device]

As described above, in the present invention, since the holding sheet is constructed by applying the adhesive on one side of the sheet and the mucoadhesive on the other side, the structure is simple and It can also be applied to such an X-ray film package. Further, it is not necessary to change the manufacturing process of the conventional X-ray film package.
