    A device and method for applying and retaining a unique data carrier to a tooth surface of an individual. The data carrier comprises a thin sheet of material having a data format unique to the individual. This data carrier is attached to the surface of the individual's tooth and is adapted for detection by a reader which can be operated by a third person. All phases of installation and detection of the carrier involve passive, noninvasive techniques which can be applied without regard to age and can be maintained as part of a permanent identification system. The system further comprises a central data bank which becomes a verification source for identifying information carried at the individual's tooth surface.

    WITH
    The invention relates to medical technology and is intended to identify a living individual through direct access to information about its name, medical condition and other necessary information, which is especially important when identifying victims of violence, dead and left unknown, whose identification is difficult due to lack of identification. or due to various other circumstances. These circumstances concern not only the dead or unconscious victims of criminal acts, but also thousands of victims of accidents, people who have lost memory and memory. consequently unconscious, incapable of communication, etc. The most serious problem
    identifying children who do not have any identification.
    The purpose of the invention is to promptly obtain the identification data of a lacti Jent that is in critical condition. ,
    FIG. 1 shows a data carrier, the first option; in fig. 2 - a separate central incisor tooth with a data carrier attached to it; in fig. 3 - data carrier, the second option; in fig. 4 — data carrier and reading system of this data; in fig. 5 - data carrier, the third option.
    The drawings show the proposed devices and methodologies for the manufacture and use of a completely new data carrier 1, installed on a test bench.
    man’s tooth to obtain direct access to information about his physical condition, his name and other necessary data. Such information may be required, for example, in critical circumstances. The data carrier literally becomes part of the user's body and is not at risk of loss, damage and cannot be forgotten. At the same time, its installation is provided by a passive and non-intrusive means.
    The essence of the method is as follows.
    The installation of the data carrier must be carried out in a dental office and can be easily combined with a regular patient visit. First, the area of the surface on which the data carrier 1 is to be installed is isolated with a cotton swab, cleaned in order to open the enamel rods.
    This operation can be carried out by a known method of acid etching applied to the tooth surface with a 50% solution of phosphoric or other appropriate acid. After that, the specified area is washed and dried. The exposure of the enamel rods is aimed at obtaining a rough surface that provides a strong bond with the bonding material, which serves as a substrate, to which the carrier 1 is attached.
    A mixed methacrylate copolymer or any known polymer that can be applied in a liquid can be used as a binding material. form, followed by curing at the site of its imposition. An example is the BIS-GMA aromatic dimethacrylate resin (bis-glycol-methacrylate), as well as cyanoacrylate systems (for detailed explanations, see G. Craig Dental Materials, 1978, pp. 1-51).
    The liquid is applied to the surface of the tooth and it flows into the structure of the enamel cores, which makes it possible to obtain a binding surface (shown by bright lines), which provides reliable mechanical connection when used as a catalyst for ultraviolet radiation or other means.
    The selected binder material must be chemically compatible with the carrier composition to form a chemical bond between them. If there is no such compatibility, everything must be done to obtain a strong mechanical bond between the polymer and the data carrier. This can be achieved by mowing the edges with a carrier or by using one of a number of well-known methods that guarantee such
    mechanical connection.
    After the bonding surface is formed and before the polymer cures, a modified or prepared tooth is placed on the tooth surface.
    0 media 1 data. Preparatory operations include chip size determination and the inclusion of a corresponding data set. After inserting the carrier 1, the data is on top of it and the substrate is coated with a second coating of transparent polymer. Typically, such a transparent polymer has the same composition as the bonding material or the first polymer, which ensures optimal bonding between the respective layers. This ensures that the data carrier is sealed by enclosing a protective polymer in the capsule, and thus the entirety of the media is reliably secured.
    5 associated with the enamel of the tooth surface. In order to guarantee tightness, several layers can be applied. Although sealing is not a significant factor, it is preferred for
    0 obtaining a structure of constant use capable of withstanding abrasion when chewing solid food, the impact of a toothbrush, etc.
    When sealing the data carrier,
    5 properly mounted on the inward-facing protected surface of the tooth, must remain fixed for many years and at the same time provide instant access to critical
    0 or other situations requiring its use.
    A data carrier, such as a chip, can have a large memory capacity, provides the ability to enter into it a large amount of various information. Each type of information can be represented by a specific code, which allows the emergency doctor to immediately use the portable reader 4 for
    0 access to the data carrier and the code set to obtain the necessary information. This eliminates the need for numerous tests that are currently required to eliminate a number of diseases that cause the same symptoms. Saving time is often a decisive factor in saving a person’s life.
    The proposed data carrier may contain ready information about the patient's allergy to certain types of medications. Scanning the data carrier allows the physician to exclude dangerous medications and take measures appropriate to the individual characteristics of the individual. This kind of data can be expanded and continuously updated if it is connected to the main database, which receives information directly from the patient’s medical history.
    The data carrier 1 is made of a thin flexible material that is compatible with the environment of the oral cavity in which it should be placed. The size of the carrier is small enough to allow it to be attached to one tooth. As the material of the carrier can be used film, Millar, metals, canton, etc. a composition that can be coated or that can be etched or modified by a data set made of aluminum, photo-oxide or another surface modifier suitable for use in. oral cavity of this particular user. The material must be chemically compatible with a binding agent or other means used to secure the carrier to the surface of the tooth.
    The dimensions of the carrier should be chosen so as not to cause the user any inconvenience whatsoever after installation and not to affect the conditions in the oral cavity. The thickness of the carrier should be as small as possible in order to avoid unpleasant sensations from the thickening on the tooth formed by it. Although FIG. 1, the thickness of the carrier is indicated by the index I and appears to be significant, it is not critical, since the sole purpose of the carrier material is that it serves as a substrate for applying a dataset, a film of such material that is quite suitable for this purpose.
    The carrier should have the smallest possible thickness that meets the requirement of applying a data set on it and installing it on the tooth surface. In fact, there is no need to use a carrier with a thickness of more than 0.5 mm, and the typical thickness is about 0.1 mm. and less.,
    The width w and height h is limited by the dimensions of the tooth surface on which the carrier is placed. The selection of a tooth affects the determination of these parameters. Selecting a larger tooth for this purpose provides a larger surface area for the data set. A smaller tooth allows the use of a limited area, but the chip sizes do not exceed an area of 5x5 mm.
    Although rectangular or square plates are shown, they may be of a different shape. These dimensions in height and width can easily be adjusted for other shapes and equivalent surface areas. FIG. Figure 3 shows a tooth that is the anterior incisor, but this does not exclude the possibility of choosing a mandibular tooth, canine or molar.
    The width and height of the data carrier or plate are respectively about 2.5 mm x 2.0 mm. It is made of a photographic film with a set of 2 data applied on it by a standard photo-method. The film is processed and cut according to the size of the surface of the tooth to which it is attached. This allows the use of media that is industrially manufactured and requires minimal cash outlay. The plate can also be made of metal, such as stainless steel, and the data can be applied to it by etching.
    The reading system comprises a sensor 3, an optical fiber light guide 4, bent in such a way as to provide access to the inner surface of the tooth. The end of the fiber is polished to ensure a clear transfer of the image data from the carrier. The image is displayed in window 5, allowing data to be continuously read from the media. In the case of the sensor 4 with the window 5, an input keyboard 6 can be mounted to enter coded information readable from the window. Window 5 also displays information entered into the keyboard to confirm the correctness of the manually entered information. This input information can then be transferred to computer 7 for processing the encoded information.
    Other variants of this design can be developed, for example, a computer can be installed in sensor 4 housing, forming a single unit of equipment. In another embodiment, a mirror probe with a magnifying lens can be used, providing direct visual reading of the alphanumeric code.
    For a direct reading, it is necessary to create a sensor with illumination, which is necessary for the case of mounting the carrier on the inner surface of the tooth. The backlight can be implemented by a light source mounted in the sensor housing. In this case, the probe must have a light guide like for
    light from the source as well as to transfer the image back to the window 5.
