Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a dental caries morbidity risk evaluation system that measures the chemical physical properties of a subject such as saliva collected from a subject and accurately evaluates the dental caries morbidity risk based on the measured values of the chemical properties.andDental caries risk assessmentOn the wayRelated.
[0002]
[Prior art]
  Conventionally, in order to diagnose the health condition in the mouth, a dentist directly inspects the mouth of the subject to examine the dental caries affliction state. This dental health checkup, for example, is typically performed regularly every 6 months, so that approximate subjects can discover and find a caries that requires complex treatment before it is formed. The person can prepare the oral environment with simple treatment.
[0003]
[Problems to be solved by the invention]
  However, how much resistance the subject's mouth has against caries, that is, the subject's dental caries risk (generally called the Caries Activity Test). There were individual differences. For this reason, some people need only to perform a health check in the mouth with a longer cycle, while others need to perform a health check of the mouth environment with a shorter cycle.
[0004]
  On the other hand, if the subject has decided on a dentist, it is possible to determine a certain degree of dental caries risk from the past history. It was difficult for an experienced dentist to accurately determine the caries risk of caries by examining only the caries risk. Therefore, the dentist may prompt the patient to revisit the patient within a short period of time, but the patient is troublesome to respond.
[0005]
  In addition, the patient who requested treatment from the dentist needs to receive appropriate treatment by the dentist, but it is difficult for the patient to fully understand the necessity of treatment that the dentist determines to be necessary. In other words, even if you look in your mouth with a mirror, it is difficult to find the initial stage of tooth decay.HealingSome patients discontinue treatment at a later stage and postpone revisiting when prompted.
[0006]
  Although the dentist points out the importance of preparing the oral environment to the patient, it is not recommended to the patient to improve the risk of caries or dental caries that do not appear on the surface to the extent that it can be visually confirmed. was difficult.
[0007]
  In addition, when a patient changes dentist due to moving, etc., the dentist who is newly in charge does not know the history of the patient and creates a new chart and treats the patient's oral environment There was a situation of understanding.
[0008]
  The present invention has been made in consideration of the above-mentioned matters, and the object of the present invention is to ensure that the subject understands the caries risk of his / her teeth accurately and is fully engaged with the dentist. A dental caries risk assessment system that can maintain the oral environment in the best possible state through communicationandDental caries risk assessmentProvide wayThere is to do.
[0009]
[Means for Solving the Problems]
  To achieve the above object, a dental caries morbidity risk evaluation system according to a first aspect of the present invention includes a measuring instrument for measuring chemical properties of a sample collected from the mouth of a subject, and dental caries from the measured values of the chemical properties. A database that records evaluation criteria data for assessing morbidity riskPossessA server having a risk evaluation function for evaluating a dental caries morbidity risk of a subject using a measured value of a chemical property measured by the measuring device;SaidData between a terminal having an evaluation output function for outputting an evaluation of a dental caries morbidity risk and the measuring device, server, and terminalInput and outputWith networkA dental caries risk assessment system  The database in the server, in addition to the evaluation standard data, treatment data corresponding to the dental condition transition data having the measured value data of the chemical properties of each subject and the dental treatment history data, and the evaluation standard data While having an electronic medical record that records treatment guideline data that gives a guideline on the basis of the above, in addition to the risk evaluation function, the server uses the measurement value data recorded in the electronic medical record and the statistics of the treatment history data of teeth. Evaluation criteria creation and update function that enables creation or change of assessment criteria data, and treatment recommendations that deliver appropriate treatment guidelines for each subject on the network according to each subject's dental caries risk assessment In addition to the evaluation output function, the terminal reviews the state transition data of each subject's teeth recorded in the electronic medical record in addition to the evaluation output function. An electronic medical chart viewing function, as well as the individual evaluation criteria input function that allows create or modify individual evaluation criteria data adjusted for each subjectIt is characterized by having. (Claim 1)
[0010]
  Therefore, the subject can measure the chemical physical properties of a sample such as saliva collected from his / her mouth using a measuring device, and can receive an evaluation of the dental caries risk based on this. Accordingly, it is possible to make an accurate judgment of the oral environment from the evaluation value of the caries morbidity risk of own teeth, and to proceed with appropriate treatment when necessary. In other words, it is possible to clearly determine the dental caries morbidity risk that has been difficult to distinguish from the measured values of chemical properties, and recognize the necessity of treatment from the evaluation.
[0011]
  In addition, although a measuring device can be arrange | positioned in a dental clinic, for example, it may distribute to each subject's home and the measuring device and the server may be connected by the network. Similarly, the server may be disposed in a dental clinic, but may be disposed in a management company that manages the server, and a plurality of dental clinics may be connected to the server via a terminal and a network. Terminals are located at each subject's home and / or dentist. In addition, the terminal does not need to be a so-called network connection terminal. An input device such as a display device (including a display unit provided in the measuring device) or a printer directly connected to the server, a printer, or the like. It may be a device. The specimen is, for example, a subject's saliva, but may be a caries-causing substance such as dental plaque.
[0012]
  The database is measured value data of chemical properties of each subject.And dental treatment history dataAn electronic medical record that records the state transition data of teethHaveSince measured value data of chemical properties relating to the subject is stored in the database as an electronic medical record, this can be used for treatment. In particular, when the dentist is changed, the contents of the electronic medical record can be presented to sufficiently communicate with the dentist.
[0013]
Moreover, The server has an electronic medical chart browsing function that enables browsing of the state transition data of the subject's teeth recorded in the electronic medical chart using the terminalBecause it is a thingThe subject can view his / her electronic medical record and make an effort to keep his oral environment in good condition. On the other hand, by viewing the electronic medical record of the subject who the dentist visits as a patient, the transition of the oral environment can be confirmed even for the first visit patient, so that more accurate treatment can be performed. In addition, it is possible to give appropriate advice to each patient such as instructions on brushing methods, points to improve eating habits, and types of dentifrices to be used so that resistance to caries can be obtained.
[0014]
  Also,While the electronic medical record has dental treatment history data of each subject as dental state transition data, the server is based on statistics of measured value data and dental treatment history data recorded in a plurality of electronic medical records. Evaluation standard creation update function that enables creation or change of evaluation standard data,In addition, a treatment recommendation distribution function that distributes appropriate treatment guidelines for each subject on the network according to the dental caries risk assessment of each subjectTherefore, it is possible to refine the evaluation standard data indicating the relationship between the measured value of chemical properties and the evaluation value of the risk of developing dental caries from the statistics of actual data, and more accurately the incidence of dental caries. Risk assessmentAnd appropriate treatment guidelines Therefore, the subject can accurately know that his / her oral environment requires treatment, and can perform early treatment without losing time.
[0015]
  In addition, it is possible to promote research in this field by adding scholars who study dental caries risk as a database administrator, or providing scholars with measurement data and statistical data on dental state transition data. it can. As chemical properties related to dental caries risk, it is conceivable to determine saliva pH and pH buffering capacity at present, but other chemical properties may be measured in the future. In other words, it is desirable that the types and values of chemical properties used as evaluation criteria can be changed or added as appropriate according to the opinions of scholars who join the dental caries risk assessment system as a database administrator or its assistant.
[0016]
  further,A terminal having a personal evaluation criteria input function that allows browsing of the state transition data of teeth recorded in the electronic medical record and creating or changing personal evaluation criteria data consisting of evaluation criteria adjusted for each subject.SoA more accurate evaluation of caries risk can be obtained by setting an evaluation standard tailored to the individual conditions of each subject.
[0017]
  in addition,The database records treatment guideline data that provides treatment guidelines corresponding to the evaluation criteria.BecauseIt becomes easier to take action according to the evaluation value of the dental caries morbidity risk, and the use value of the dental caries morbidity risk evaluation system increases accordingly.
[0018]
[0019]
  When the treatment guideline data includes subject treatment guideline data for a subject and dentist treatment guideline data for a dentist (claims)2), The subject can obtain easy-to-understand treatment guidelines in plain language, and the dentist can obtain specialized and detailed medical guidelines, which can be used to improve skills. Moreover, when a subject visits a dentist as a patient, he / she can feel relieved by the accurate and professional explanation of the dentist, and can promote mutual communication.
[0020]
  When the database has a list of oral environment improving drugs (Claims)3), The subject can easily select and purchase an appropriate drug in order to improve his or her oral environment. In addition, a pharmaceutical company that manufactures the drug can promote the sales of the drug by registering the efficacy of each drug in the oral environment improving drug list.
[0021]
  When the server has an examination reservation function for assigning a right to use a measuring instrument to each subject and receiving a dental caries risk assessment by accessing from the terminal of the subject via the network (invoice) Term4), By accessing the server via the network, the subject can evaluate his / her dental caries risk at a convenient time, such as by renting a measuring instrument. Will improve.
[0022]
  The measurement of chemical properties using a measuring instrument may be performed at the subject's home by sending the measuring instrument from the administrator of the dental caries morbidity risk assessment system to the subject. The sample collected from the examiner's mouth may be sent to the inspection company or the administrator of the dental caries morbidity risk evaluation system to measure the sample on the side of the dental caries morbidity risk evaluation system. Furthermore, the chemical property of the subject may be measured by visiting the examination site provided by the dentist or examination company equipped with the measuring instrument.
[0023]

And is operated by the administrator 14 of the database 5. However, the server 4 may be arranged in each dental clinic 9... Or inspection company 9 ′ and managed by each dentist 10 or inspector 10 ′. In this case, it is also possible to use an existing information processing apparatus (in this example, terminals 6B and 6C) as the server 4 in each dental clinic 9.
[0033]
  The database 5 is not necessarily recorded in the storage unit in the server 4, and it goes without saying that a separate server for managing the database 5 may be provided. However, by managing the database 5 by the management company 13 as shown in this example, it is possible to manage information that is not captured by the framework of the dental clinic 9, and to evaluate the dental caries risk as described later. The information provided can be collected more widely and abundantly.
[0034]
  The measuring device 3 uses, for example, saliva collected from the mouth of the subject 2 as a specimen, and measures its pH and pH buffering ability as chemical properties. Various forms of the measuring device 3 are conceivable. For example, in the home 8 of the subject 2, a stick type configured to be connectable to a terminal 6A possessed by the subject 2 by an interface of a predetermined standard such as USB. The measuring instrument 3A can be considered.
[0035]
  As another form of the measuring instrument 3, a stationary measuring instrument 3B configured to be connectable to terminals 6B, 6C,. Good. Further, like the measuring instruments 3B and 3C shown in FIG. 1, a display unit 3a having a display function of measured values of chemical properties and an evaluation output function of a dental caries morbidity risk is provided, and also has the function as the terminal 6. May be.
[0036]
  In addition, the measuring device 3 can be directly connected to the Internet 7 so that the measuring device 3B can have a function as the terminal 6. Further, the measuring device 3 may be a measuring device 3C which manages the measuring device 3 on the inspection company 9 'side.
[0037]
  The database 5 is, for example, an electronic medical record 15 having state transition data 15A of the oral environment of each subject 2, personal data 15B of the subject 2, and personal evaluation reference data 15C described later, at least measured values of chemical properties And evaluation standard data 16 indicating the relationship between the evaluation value of the dental caries morbidity risk, registered dentist data 17 indicating information regarding the registered dentist cooperating with the dental caries morbidity risk evaluation system 1, and recommendation It has oral environment improving drug data 18 indicating information related to the oral environment improving drug.
[0038]
  The state transition data 15A is, for example, measurement value data 15a composed of a history of measurement values of chemical properties of a sample collected from the mouth of the subject 2 or treatment content data specific to the subject 2 added by the dentist 10. The dental treatment history data 15b of the subject 2 is included. The personal data 15B includes, for example, the address, name, age, gender, contact information (may include an e-mail address) of the subject 2 and the like. Further, the personal evaluation standard data 15C is a personal evaluation standard adjusted for each subject 2 according to the situation.
[0039]
  The evaluation reference data 16 includes not only data indicating the relationship between the measured value of chemical properties and the evaluation value of the risk of dental caries, but also treatment guideline data corresponding to the evaluation, for example, “rapid treatment is necessary. It is conceivable to include the words “become recommended”, “recommend diagnosis by dentist”, “recommend regular diagnosis”, and “there is no risk of cavities at present”. Further, it is desirable that this treatment guideline data separately stores a general treatment guideline 16a that is easy to understand for the subject 2 described later and a specialized treatment guideline 16b that gives sufficient information to the dentist.
[0040]
  Furthermore, it is desirable that the evaluation criteria recorded as the personal evaluation criteria data 15C include treatment guideline data in words, and general treatment guidelines that are easy to understand for the subject 2 and sufficient information for the dentist. It is desirable to memorize separately the professional treatment guidelines that give
[0041]
  In either case, in this example, the treatment guideline data for outputting the treatment guideline (word) corresponding to the evaluation is provided in a part of the evaluation reference data, but both are distinguished and stored in the database. You can also.
[0042]
  FIG. 2 is a diagram for explaining an example of the measuring device 3 (3A). In FIG. 2, 20 is a main body of the measuring instrument 3A, 21 is a sensor unit, and 22 is a cable for connecting the main body 20 to the terminal 6A (see FIG. 1) using a USB or the like. The main body 20 has an arithmetic processing unit 23 that obtains a measured value of pH as an example of chemical properties of saliva measured by the sensor unit 21, and a display unit 24 that can display, for example, a measured value obtained by the arithmetic processing unit 23. And an operation button 25 for the user of the apparatus to operate the measuring instrument 3A. The operation button 25 is, for example, a measurement button.
[0043]
  The sensor unit 21 is configured to be detachable from the main body 20. For example, a sensor surface 26 in which a measurement electrode and a comparison electrode made of ISFET are formed on the same plane, and the sensor surface 26 is a bottom surface. And a container 27 for containing saliva collected from the mouth of the subject 2.
[0044]
  The sensor surface 26 of this example shows an example in which the evaluation of the dental caries risk is judged by the measured value of pH, but the sensor surface 26 is composed of a measurement electrode of ISFET for pH measurement and a comparison electrode. Instead of this pH measurement, it is also possible to use ORP measurement or other chemical properties such as calcium or other ion concentrations or protein amounts as judgment criteria. That is, by attaching a sensor unit 21 having a different sensor surface 26 to the main body 20, it is possible to measure another chemical property of a specimen such as saliva or plaque collected from the subject 2.
[0045]
  It is also conceivable to measure a plurality of chemical properties on the sensor surface 26 and judge the risk of dental caries by comprehensively judging each chemical property. In addition, when measuring other solution property parameters such as ORP and calcium ions, it goes without saying that the configuration of the electrode on the sensor surface 26 is changed. In any case, the measured value S0 of each chemical property measured by the sensor surface 26 is transmitted to the terminal 6A via the signal cable 22, and is transmitted to the server 4 via the terminal 6A.
[0046]
  The container 27 is provided with a lid body 28. The lid body 28 is rotatable by a hinge 29, and is fitted in a watertight manner to the edge of the container 27 with the lid body 28 closed. And a lid main body 30 formed with an opening 28b in the upper portion of the container 27, and the opening 28b can be completely closed by slidably engaging with the lid main body 30. The movable body 31 is made up of. In order to prevent leakage of saliva contained in the container 27, it is desirable that it can be completely closed.
[0047]
  The subject 2 shown in FIG. 1 accesses the server 4 via his / her own terminal 6 </ b> A and makes an application for use of the dental caries morbidity risk evaluation system 1. 2 and the measuring instrument 3 can be sent from the inspection company 9 '. Here, when the electronic medical record 15 is created, an accurate electronic medical record 15 is created by interrogating the past dental examination history of the subject 2 on the web or by sending documents. At the same time, the ID and password of the subject 2 that will be required when using the dental caries morbidity risk assessment system 1 of the present invention are determined.
[0048]
  That is, the server 4 assigns the right to use the server 4 of the evaluation system of the present invention to each subject 2 by accepting the use application, and the usable measuring instrument 3A is assigned to the subject 2. By sending it, it has an examination reservation function that can accept the dental caries morbidity risk evaluation that assigns the right to use the measuring device 3A to the subject 2. Note that this application for use is not limited to being made via the Internet 7, but may be made by the subject 2 filling out an application form in a certain format and sending it to the inspection company 9 '. Good.
[0049]
  When the measurement device 3A reaches the home 8, the subject 2 connects this to the terminal 6A and measures the chemical properties of his / her saliva as a specimen. FIG. 3 is a diagram for explaining a method for measuring chemical properties using the measuring device 3A. Therefore, a method for measuring the chemical properties of saliva using the dental caries morbidity risk evaluation system 1 of the present invention will be described with reference to FIG. However, the dental caries morbidity risk evaluation system 1 of the present invention does not limit the configuration of the measuring instrument 3 and the method for measuring chemical properties shown below.
[0050]
  First, as shown in FIG. 3A, saliva is collected from the mouth of the subject 2 using a sterilized syringe 35 or the like. At this time, the amount of saliva to be collected is confirmed by, for example, a scale (not shown) provided on the syringe 35, and the amount necessary for measurement is collected. This amount depends on the capability of the sensor unit 21, but is shown in FIG.
In the case of forming the sensor surface 26 using ISFET as in the example, it is sufficient to collect 0.5 mL or more, for example.
[0051]
  Next, as shown in FIG. 3 (B), the collected saliva 36 is confirmed with a scale provided on the syringe 35 and the like and dropped by exactly 0.5 mL onto the sensor surface 26 and accommodated in the container 27. At this time, the saliva 36 may be accommodated with the lid body 31 open, or the saliva 36 may be accommodated from the opening 28b by opening the movable body 31 with the lid body 31 closed. Note that the present invention does not limit the amount of saliva 36 used for the evaluation of dental caries morbidity risk. Depending on the performance of the sensor surface 26, it is possible to measure using a much smaller amount of saliva 36.
[0052]
  Next, the measurement button 25 is operated to measure the pH of the saliva 36. Note that, as in this example, the power of the measuring instrument 3A is supplied from the terminal 6A side, so that the operation can be simplified without operating the power supply. However, a separate power supply may be provided. Needless to say. In addition, this initial pH measurement may automatically begin as saliva 36 is dripped onto the sensor surface 26.
[0053]
  When the measurement of the pH is completed, the arithmetic processing unit 23 stores the pH value, and then is sent to the apparatus user from the inspection company 9 ′ by attaching an alarm sound or display to the measuring device 3A. Outputs a message prompting to drop the acid.
[0054]
  FIG. 3C is a diagram showing a procedure for mixing a predetermined ratio of acid 37 into saliva 36. The acid 37 to be mixed here is, for example, a 0.1 mol / L hydrochloric acid aqueous solution. In this case, 10 μL is measured and injected using a desired chemical solution injector 38. (That is, 0.000002 gram equivalent is mixed with 1 mL of saliva)
[0055]
  FIG. 3D is a diagram showing a procedure for mixing the injected acid 37 with the saliva 36. At this time, by completely closing the lid 28, the container 27 can be sealed, and the saliva 36 is prevented from leaking out when the measuring instrument 3A is shaken well and stirred in order to sufficiently mix the acid 37 with the saliva 36. be able to. Moreover, in order to fully exhibit the pH buffering ability of the saliva 36, after the acid 37 is dropped, the second pH measurement can be performed after leaving for a predetermined time (about 30 seconds to about 1 minute).
[0056]
  The leaving time is preferably set by a program executed by the arithmetic processing unit 23. That is, by outputting a message prompting to perform the second pH measurement with an alarm sound or display after waiting for a predetermined time such as 30 seconds from the time when the arithmetic processing unit 23 presses the measurement button 25, More stable measurement can be performed without trouble.
[0057]
  Next, when the measurement of the pH value when 10 μL of the hydrochloric acid aqueous solution is mixed is completed, the measuring device 3A outputs a 10 μL hydrochloric acid aqueous solution once again to the apparatus user, and the above-described FIG. Repeat the process of D). In this way, the dropping of the hydrochloric acid aqueous solution was repeated three times, and the change in pH value at that time was measured, so that a total of 30 μL hydrochloric acid aqueous solution (0.000006 per 1 mL of saliva was added to 0.5 mL of saliva 36. The change in pH value is measured when the acid 37) in a predetermined ratio of gram equivalent is mixed.
[0058]
  In addition, as in this example, the acid 37 is added in three portions at a rate of 0.000002 gram equivalent to 1 mL of saliva, and each change in pH at that time is measured, whereby the saliva 36 has It is possible to more accurately determine the pH buffer capacity. However, it is needless to say that a predetermined ratio of the acid 37 that gives the final result may be dropped at once. In this case, the time required for measurement can be shortened.
[0059]
  In addition, in this example, an example in which the acid 37 is manually dropped on the saliva 36 so as to clarify the method for measuring the pH buffering capacity is shown, but the present invention does not limit this point. That is, the measuring instrument 3A is programmed to automatically mix an appropriate amount of acid 37 from an acid container (not shown) of the measuring instrument 3A at an appropriate timing, thereby reducing the operation by the subject 2. The chemical properties can be measured easily.
[0060]
  The measured values S0 such as pH and pH buffering capacity are stored in the database 5 in the server 4 via the terminal 6A and the Internet 7, and the server 4 is evaluated based on the dental caries morbidity risk evaluation program P. Referring to the data 16, the measured values S0 of the respective chemical properties are converted into the dental caries morbidity risk evaluation S1 and the treatment guidelines 16a and output to each terminal 6A.
[0061]
  FIG. 4 is a diagram showing the results of actual measurement of changes in pH when 0.1 μl / L hydrochloric acid aqueous solution was dropped three times by 10 μL each into 0.5 mL saliva collected from 15 subjects 2. It is. The evaluation reference data 16 is a relationship obtained based on such measurement values, and the evaluation is recorded as a table, for example.
[0062]
  Specifically, it can be determined that the saliva 36 whose pH measured in a state where a 30 uL hydrochloric acid aqueous solution is dropped is, for example, 5.7 or more, has a statistically low risk of dental caries (i.e., LEVEL0). Further, for example, when the pH is 5.4 or more and 5.7 or less, the risk is moderate (LEVEL 1), and when the pH is less than 5.3, the risk is high (LEVEL 2). This range does not limit the present invention, and does not limit the representation of dental caries risk in three stages.
[0063]
  In addition, as shown in FIG. 4, there are individual differences in how the pH buffer capacity appears when the acid 37 is dropped. Then, by using the dental caries morbidity risk evaluation system 1 of the present invention, using the state transition data 15A of a large number of subjects 2, the measured values of the chemical properties of the collected samples and the subjects 2 Therefore, it is possible to update or create more realistic evaluation reference data 16. On the other hand, it is possible to create personal evaluation reference data 15C that is determined from the individual history of each subject 2 and that takes into account its unique tendency.
[0064]
  The creation and update of the personal evaluation reference data 15C can be performed, for example, when the dentist 10 who has examined the subject 2 as a patient inputs it from the terminal 6B and stores it in the database 5. Thereby, more accurate personal evaluation reference data 15C can be created according to the skill of the dentist 10. At the same time, additional data such as treatment guidelines expressed in words may be added by the dentist 10 or the like.
[0065]
  Note that the evaluation S1 of the dental caries morbidity risk may be delivered to the subject 2 in the form of e-mail, for example, as shown in FIG. In other words, the server 4 has an evaluation distribution function for distributing the dental caries morbidity risk evaluation to the subject 2 using e-mail or the like.
[0066]
  The server 4 also performs the dental caries morbidity risk assessment S.₁ It is desirable for the subject 2 who has a bad condition to have a treatment recommendation distribution function for transmitting a treatment guideline 16a including advice or treatment recommendation according to this by e-mail or the like.
[0067]
  The example shown in FIGS. 2 and 3 shows an example in which the subject 2 carries out a saliva test using the measuring device 3A possessed by the subject 2, but the present invention does not limit this point. That is, the subject 2 puts his saliva in a prescribed container and sends it as a specimen to the dental clinic 9... Or the inspection company 9 ′ side, or by visiting the inspection site, so that the dental clinic 9. It is also possible to undergo an inspection using measuring instruments 3B, 3C,.
[0068]
