Description
Means for Identifying a Human Being
CROSS REFERENCE TO RELATED APPLICATIONS
This application represents the first application for a patent directed towards the invention and the subject mailer.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method of applying an identification device upon the human body, a method of obtaining identification data from a human body and a kit for applying an identification device upon the human body.
2. Description of the Related Art
Typically, identification devices or tracking devices are an electronic chip attached to an individual and which can be identified on the individual at a later time point. Identification devices and tracking devices range from is electronic wristhands, bracelets or badges sewn into items of clothing to specially tagged pyjamas or other items of clothing. The identification device or tiacking device may include a passive transducer, such as a radio frequency identification device (RFID) that works in conjunction with a reading device to monitor the identity and/or movement of an individual if they move beyond a certain range. This is particularly directed for use on children. Alternatively, the identification device or tracking device may include a device to take advantage of Global Positioning Satellite (GPS) technology for the monitoring of the location of an individual.
There are also tracking services that offer a pay-as-you-go tracking service that follows the SIM (subscriber identity module) card in a mobile phone, and in particular in a child's mobile phone. Such tracking services use a combination of mobile phone and Global Positioning Satellite (GPS) technology to track an indMdual by computer to within a few metres.
An obvious drawback to these existing identification devices or tracking devices is that they are disposable and could easily be removed from the individual under surveillance. The item of clothing into which the tracking device was sewn, the wristband or the mobile phone could easily become separated from the individual.
A non-removable permanent microchip implant would overcome the drawbacks of the above-described identification or tracking devices. The microchip implant could be inserted into the individual, for example, sub-cutaneously. However, an operation on an individual to specifically insert a microchip implant raises a raft of ethical questions, to which there is no unified satisfactory answer.
An alternative to these non-permanent identification and tracking devices and permanent microchip implants is the non-surgical positioning of an electronic chip within the oral cavity. In particular, an alternative is the positioning and attachment of an electronic chip in a naturally-occurring fissure in a tooth through the use of dental fissure sealant material. Such tooth located tracking devices have been described. However, such devices of the prior art require drilling into a cavity of the tooth.
An invention overcoming all of the aforesaid disadvantages of the prior art is provided by the presently claimed invention.
BRIEF SUMMARY OF THE INVENTION
According to an aspect of the present invention, there is provided a method of applying an identification device upon the human body, comprising the steps of embedding a transducer within a naturally-occurring fissure in a tooth; and securing said transducer within said fissure using fissure sealant.
According to a second aspect of the present invention, there is provided a method of obtaining identification data from a human body, comprising the step of reading data from a transducer secured within a naturally-occurring so tooth fissure by fissure sealant.
According to a third aspect of the present invention, there is provided a kit for applying an identification device upon the human body, comprising a transducer, fissure sealant, and a fissure sealant applicator device.

Figure 1 shows a dentist using a dental tool in the oral cavity of a patient; Figure 2 shows an example of a fissure in a molar tooth; Figure 3 shows preparation by a dental practitioner of a transducer and fissure sealant before securing in a tooth fissure; Figure 4 represents the passive transducer as a miniature radio frequency identification device (RFID) device; Figure 5 details a fissure in a molar tooth filed with fissure sealant; Figure 6 represents detection of the radio frequency identification device using a magnetic radiation-emitting reading device; and Figure 7 illustrates a reading device having a display screen.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 It is known for a dentist to use tools such as drill 101 to remove decay from teeth and facilitate the introduction of fillings. Fillings are introduced into a tooth cavity once decay is present in a tooth.
However, methods to prevent decay occurring are preferably employed.
Such methods may include increased application of fluoride on teeth, the incorporation of anti-microbial agents in toothpaste and mouthwashes, and passive immunisation.
Furthermore, a common procedure used in the dental profession as a preventative method to protect teeth from decay is to use fissure sealant.
Assure sealant is a plastic-like coating that is applied to the molar and premolar teeth in order to protect them from decay. The fissure sealant acts by creating a protective layer that prevents food particles and bacteria from getting trapped in between teeth and in the small grooves and pits in teeth.
Fissure sealant material has been used over the course of several decades and is well known in the dental profession to prevent tooth decay. The term fissure sealant may also be known as protective sealant, dental sealant, dental filler material, dental glaze, dental cement, dental adhesive or dental bonding agent.
Fissure sealant is generally used in the form of a protective liquid that is painted onto the biting surfaces of the back teeth. The molar and premolar teeth are most suitable for the application of fissure sealant. The process of application only takes a few minutes for each tooth. A concentrated beam of ultra-violet (UV) light is shone onto the fissure sealant to allow it to harden in situ in the tooth fissure-Once hardened, fissure sealant can remain in place for many years. In some people, the fissure sealant generally lasts for a minimum of three to five years whilst in others, the fissure sealant applied to a child can last into adulthood. It is easy for the individual to observe if the fissure sealant is broken or has been dislodged. Since the application of fissure sealant is a routine procedure, the fissure sealant is easily replaced on a routine visit to the dental surgery.
Fissure sealant is normally applied as soon as the first adult molar teeth appear, at about six to seven years of age. The other molar teeth are usually fissure sealed as they present, which is normally between the ages of eleven and fourteen.
The fissure sealing process is quick, non-invasive and painless.
Figure 2 An example of a naturally-occurring fissure 201 in a molar tooth 202 is illustrated in Figure 2. This fissure 201 is small in size and therefore the transducer must be of a suitable size so that it fits inside fissure 201. Fissures in any of the molar or premolar teeth could be used for placing the transducer.
The transducer may be a passive or an active transducer.
The tooth is prepared by first thoroughly cleaning the tooth using appropriate dental tools and brushes. An air abrasion technique may be used to clean the surfaces of the tooth. The surface of the tooth is also roughened to help the fissure sealant adhere to the tooth when it is appUed. An etching gel may also be used to increase the adherence of the fissure sealant to the tooth.
In an embodiment, the transducer, which may be passive, is coated in fissure sealant by holding the transducer with forceps and submerging it in fissure sealant contained in a small dish. The transducer may be a passive transducer and may be a radio frequency identification device. The passive transducer is then positioned within the fissure of a tooth. Once positioned, the passive transducer is fixed in position through the addition of fissure sealant Fissure sealant is added to the fissure in a liquid form using a suitable device, which may be a syringe or needle-like applicator. A concentrated beam of UV is light is shone onto the fissure sealant to allow it to harden in situ in the tooth.
The passive transducer is then securely attached inside the oral cavity of an individual. Once hardened, fissure sealant can remain in place for many years.
This will be a minimum of three to five years, and in many cases, significantly longer. Therefore, the passive transducer is securely attached in a tooth fissure within the oral cavity for many years. This secure mode of attachment is therefore advantageous over existing identification or tracking devices, such as bracelets or items of clothing, which are easily detached from the individual, either voluntarily or against the individual's will, for exampLe in an abduction.
The presence of the passive transducer within the oral cavity does not affect the use of the oral cavity by the recipient of the passive transducer, for example, speaking and eating activities are unaffected. Furthermore, the individual, or the parents/guardians of the individual do not need to remember to attach the identification device on a regular basis. In many cases, the individual in which the passive transducer has been attached becomes unaware of its presence in the oral cavity.
In another embodiment, the transducer may be an active transducer.
The active transducer takes advantage of Global Positioning Satellite (GPS) technology for the monitoring of the location of an individual.
Figure 3 The passive transducer may be provided in a blister pack 301. The passive transducer may be a radio frequency identification device. The blister pack may be similar to those used to house disposable contact lenses or tablets. Each pouch of the blister pack containing a passive transducer can be opened just before the passive transducer is required for use. The passive transducers can therefore advantageously be stored in a convenient and io hygienic manner.
The tooth into which the passive transducer is to be positioned is selected. Once the tooth has been prepared by thoroughly cleaning the tooth using appropriate dental tools and brushes, one of the passive transducers 302 is removed from the blister pack.
Fissure sealant is prepared and the passive transducer is coated in fissure sealant by holding the passive transducer with forceps and submerging the passive transducer in fissure sealant contained in a small dish. The passive transducer is carefully positioned within the fissure of the tooth.
Fissure sealant material is then added to the tooth fissure, in the remaining spaces over and around the passive transducer to securely attach the passive transducer within the fissure of the tooth.
The fissure sealant may be a resin-based sealant or may be comprised of glass ionomer cement.
In one embodiment, the fissure sealant may be formulated from any resin system known by those skilled in the art to be suitable as a fissure sealant. In an embodiment, the fissure sealant includes bisphenol-A diglycidyl dirnethacrylate (bis-GMA), bisphenol-A dimethacrylate, triethylene glycol dimethacrylate and other similar acrylic monomers which are well know to those skilled in the art.
In one embodiment, the fissure sealant itself may be provided in the form of a kit, comprising at least three elements. The first element may comprise polymerizable monomers and a polymerization catalyst such as a peroxide catalyst. Preferably, the peroxide catayst may be benzoyl peroxide.
The amounts of polymerization catalyst used would be well known by those skilled in the art. The second element may comprise polymerizable monomers and an accelerator to activate the catalyst. The accelerator is preferably an amine. A colorant, if desired, may also be added to either element. The third element may comprise an applicator device. The applicator device may be any suitable needle-shaped applicator device that is capable of dispensing small rn amounts of fissure sealant into the fissure of a tooth. In a preferred embodiment, the applicator device is a syringe.
In an alternative embodiment, an acrylic resin may be used which uses a light activatable photoinitiation catalyst instead of a free radical catalyst and an accelerator. Preferably, such light activatable photoinitiation catalysts are activated by ultra-violet light.
In another embodiment, the fissure sealant may comprise a glass-ionomer cement. Glass-iononler cements may contain fluoride and thereby possess a cariostatic effect due to fluoride release. However, it is accepted by those skilled in the art that glass-ionorner cement-based fissure sealants have a shorter durability than the resin-based fissure sealants. The strength of glass-ionomer cement is reduced relative to that of the resin-based fissure sealants.
However, any material suitable for use as fissure sealant within the oral cavity may be deployed in the presently claimed invention.
Figure 4 In an embodiment, the passive transducer is a miniature radio frequency identification device (RFID) 401. The device is passive and as such is energised by magnetism that induces a current in a coil 402. In known applications, coils may typically have the size of a coin or may be larger, such as coils included in modern passports. Larger coils require less energy or
B
alternatively, detection may occur at a greater distance.
In this example, given that it is necessary to include the entire device within a tooth fissure, the coil is relatively small.
Figure 5 A filled fissure 501 is shown. The transducer, which may be passive or active, is totally contained within the fissure and the inclusion of the device has no effect upon day to day activity.
The protective fissure sealant used may be of a colourless natura However, a fissure sealant having a colourless nature makes it difficult to io ensure that the transducer remains suitably positioned within the fissure of the tooth, and also to evaluate the integrity of the tooth, the transducer and the protective fissure sealant during routine examination by the dental practitioner.
Fissure sealant having a colourless nature may also be difficult to apply as it may be challenging to ensure that all surfaces of the fissure have been adequately coated.
Therefore, the protective fissure sealant used may include inorganic pigments to increase the visibility of the sealant. An example of such a pigment is titanium dioxide pigment. However, the incorporation of inorganic pigments such as titanium dioxide may affect the viscosity of the fissure sealant and make it more opaque. This also makes it difficult for the dental practitioner to evaluate the integrity of the tooth, the transducer and the protective fissure sealant during routine examination.
Fissure sealant with other suitable dyes or colorants may be used in accordance with this invention to increase the ease of application of the fissure sealant into the tooth fissure. The easier the fissure sealant is to apply to the tooth fissure, the easier it will be for the dental practitioner to accurately position the passive transducer within the fissure of the tooth.
Figure 6 A reading device 601 includes an energising coil configured to emit magnetic radiation. In an embodiment, the reading device may be of a size that can be conveniently handheld. This magnetic radiation is detected by coil 402 within the tooth fissure thereby inducing a current. The current is supplied to the radio frequency identification device (RFID) 401 that then retransmits energy in a modulated form so as to present unique identification data to device 601.
In one embodiment, the reading device is able to detect coil 402 over a distance of 5 metres.
Figure 7 io Reading device 601 includes a display screen 602. The reading device emits magnetic radiation and this is detected by coil 402 of the radio frequency identification device, housed within the tooth fissure. The induced current is supplied to the RFID 401 that then retransmits energy in a modulated form so as to present a unique number to reading device 601. Thus, after performing an energising function, unique identification data is shown on display screen 602.
The method of applying an identification device upon the human body and reading identification data identifying an individual as described and claimed herein has numerous advantages over existing methods for identifying individuals.
The application of an identification device or chip upon the person is known as such.
Tracking devices such as electronic wristbands, bracelets or badges sewn into items of clothing to specially tagged pyjamas or othei items of clothing or attached to a mobile phone are currently available for the monitoring and tracking of children. However, the introduction of an identification device into a tooth fissure, in accordance with the invention described and claimed herein, is considered to be significantly advantageous over these existing methods of identification. In particular, in the presently claimed invention, the passive transducer cannot be mislaid or detached from the individual, in the manner that an item of clothing or a mobile phone may easily become separated from the individual.
The introduction of chips into animals, such as domestic cats and dogs, is performed on a routine basis However, having regard to human beings, ethical problems exist in terms of the insertion of devices within the body.
However, the introduction of a device into a tooth fissure, in accordance with the invention described and claimed herein, is seen to be considerably less intrusive.
The invention described and claimed herein therefore has wide io application for use in the identification of individuals, and in particular children.
There are numerous advantages over existing identification methods that would be appreciated by parents and guardians.
Furthermore, the device could have particular application in military situations where an independent identification may be considered desirable.
The method for identifying human beings described and claimed herein could be used to monitor members of military forces. Further still, in situations where police forces and armies are being deployed, such as in Afghanistan, the device could be deployed to restrict fraudulent activities. Thus, troops on a payroll for example could be accounted for.
