Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dental X-ray film package used for dental X-ray photography.

[Prior Art] Generally, dental X-ray film is stored in a bag-like package that transmits X-rays but not light.
A package containing the X-ray film is inserted into the oral cavity to take an X-ray photograph of the affected area. Such a dental X-ray film package will be explained with reference to the drawings.

FIG. 3a is a plan view of a conventional dental X-ray film package, and FIG. 3b is a sectional view taken along line b in FIG. 3a. In the figure, reference numeral 1 denotes a package constructed using a synthetic resin sheet that is opaque and transmits X-rays. 2 is the top surface of the package 1, 3 is the bottom surface, 4 is a folded part that is folded back at one end of the top surface 2 and inserted inside the bottom surface 3, 5 and 6 are the side edges of the package 1, and 7 is the bottom surface 3 and folded back. An adhesive 8 is an X-ray film wrapped inside the package 1. By welding the upper surface 2 and the lower surface 3 at the side edges 5 and 6, the X-ray film 8 is sealed within the package 1,
This constitutes a dental X-ray film package. This dental X-ray film package is used as shown in FIG. 4 in photographing an affected area of a tooth.

FIG. 4 is a partial sectional view of the oral cavity. In the figure, 11
are the upper and lower teeth, 12 is the gum, 13 is the pulp inside the tooth 11, 14 is the cheek, and 15 is the tongue. Further, 1 is a dental X-ray film package shown in FIGS. 3a and 3b, and 8 is also an X-ray film. Reference numeral 16 indicates a support member for supporting the dental X-ray film package 1.

When performing X-ray photography, first, the end surface of the support member 16 is attached to the dental X-ray film package 1 with adhesive.
Glue it to the appropriate places. Next, the dental X-ray film package 1 is placed on the tongue side opposite to the cheek 14 in the vicinity of the affected area. At this time, supporting member 1
6 projects from the dental X-ray film package 1 almost perpendicularly in the direction of the cheek 14. Next, this protruding support member 16 is bitten with the upper and lower teeth 11. In this state, the dental X-ray film package 1 is supported in the oral cavity, and by irradiating X-rays as shown by the arrow
A line image can be obtained.

However, using such a support member 16 requires the effort of taking it out from the support member storage location and attaching it to the dental X-ray film package 1 every time an image is taken, which is extremely troublesome. Moreover, depending on the purpose of photographing, it may not be possible to use such a support member 16. Such a case will be explained with reference to FIG.

FIG. 5 is a partial sectional view of the inside of the oral cavity during endodontic therapy. In the figure, parts that are the same as those shown in FIG. 4 are given the same reference numerals, and description thereof will be omitted. 18 is the inflamed area, 1
9 is a hole made in the tooth 11, and 20 is a cleanser for extracting the pulp. Endodontic therapy is performed as follows. That is, when the inflamed area 18 has occurred at the root end of the tooth 11, the dentist makes a hole 19 in the occlusal surface of the crown of the tooth 11, and inserts the cleanser 20 (pulp extraction needle) from there to the pulp 13. and dental pulp 13
At the same time, the pulp cavity is expanded using a reamer (root canal expansion), and the inflamed area 18 is removed.
reach. Thereafter, the inflamed area 18 is treated through the expanded pulp cavity after pulp extraction. After the treatment of the inflamed area 18 is completed, the hole 19 is filled with an appropriate filling material.
The tooth 11 is then covered.

[Problem to be solved by the invention] By the way, in such endodontic therapy, it is important to know where the tip of the cleanser 20 reaches in the pulp region and how far away it is from the inflamed area 18. This is an extremely important matter for proper implementation. In order to know this, X-ray photography is performed with the cleanser 20 or reamer inserted. When taking X-rays in such a state, the upper and lower teeth 11 cannot be brought together, so
It is clear that the support member 16 shown in FIG. 4 cannot be used to support the dental X-ray film package 1. Therefore, conventional methods for supporting and fixing the X-ray film package during X-ray imaging in endodontic therapy include holding the X-ray film package with your fingers or simply placing it against the tooth 11. was taken. However, with such means, the support of the dental X-ray film package 1 becomes extremely unstable, and the dental X-ray film package 1 moves during imaging, making it difficult to obtain a clear X-ray image. There were often situations where this was not possible.

The present invention was made in view of these circumstances, and its purpose is to solve the conventional problems and
To provide a dental X-ray film package that can easily and reliably support a radiograph film.

[Means for Solving the Problems] In order to achieve this object, the present invention provides a dental treatment comprising an X-ray film and a packaging body that is an opaque sheet that transmits X-rays and houses the X-ray film. The X-ray film package is characterized in that an adhesive capable of sticking to mucous membranes is provided on one side of the package.

[Function] When the adhesive provided on the dental X-ray film package is pressed against the gingiva of the area to be radiographed, the dental X-ray film package is held in a state of being adhered to the gingiva.

[Example] Hereinafter, the present invention will be explained based on the illustrated example.

FIG. 1a is a plan view of a dental X-ray film package according to an embodiment of the present invention, and FIG. 1b is a sectional view taken along line b in FIG. 1a. In the figure, the same parts as those shown in FIGS. 3a and 3b are designated by the same reference numerals, and the explanation thereof will be omitted. Reference numeral 22 denotes a mucosal adhesive that can adhere to the skin and mucous membranes of the human body, and is applied to a part of the upper surface 2 of the dental X-ray film package 1. Various types of adhesives have been studied in recent years, and they are mainly composed of water-soluble polymers, and are being studied as adhesives for bonding electrodes to the human body, for example, when creating electrocardiograms, and are being used in practical applications. It has reached a stage. Since such adhesives are mainly composed of synthetic resin and do not contain lead or the like, they have the property of transmitting X-rays. 23 is a release paper that covers the mucoadhesive 22.

A method of using such a dental X-ray film package will be explained based on FIG. 2. FIG. 2 is a partial cross-sectional view of the oral cavity as shown in FIGS. 4 and 5, and the same parts as those shown in FIGS. 4 and 5 are given the same reference numerals and explanations are omitted. do. X
At the time of radiography, the dental X-ray film package of this embodiment is first taken out and the release paper 23 is peeled off. In this state, the mucoadhesive 22 is exposed on the surface. Next, the dental X-ray film package 1 is positioned at an appropriate position on the lingual side of the tooth 11 near the affected area to be photographed, and the exposed mucosal adhesive 22 is pressed against the gum 12 at that position. . As a result, the dental X-ray film package 1 is adhered to the gums 12 and is supported reliably. In this state, X-rays are irradiated, and after irradiation, the dental X-ray film package 1 is
It is peeled off from 2. This peeling is easily done without damaging the gums 12.

As described above, in this example, a mucosal adhesive is applied to a part of one side of a dental X-ray film package, and the mucosal adhesive is adhered to the gingiva during X-ray imaging to form a dental X-ray film. Since the package is supported, it can be easily and reliably supported without using any supporting member. Furthermore, the dental X-ray film package can be supported in endodontic therapy without any hindrance to the endodontic therapy.

In addition, in the explanation of the above example, the mucosal adhesive was explained as being applied to a part of one side.
The location to be coated can be selected arbitrarily, and it can also be coated on the entire surface of one surface, or a portion or the entire surface of both surfaces.
