Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is a dental caries risk assessment system that measures the chemical properties of a subject such as saliva collected from a subject, and performs an accurate dental caries risk assessment based on the measured values of the chemical properties. The present invention relates to a dental caries risk assessment method and a dental caries risk assessment program.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in order to diagnose the state of health in the mouth, a dentist has directly inspected the inside of the mouth of a subject to examine the state of dental caries. This dental checkup, for example, is generally performed periodically, for example, every six months, so that the approximate subject can find out the caries that require complicated treatment before it is The person can prepare the oral environment only by receiving simple treatment.
[0003]
[Problems to be solved by the invention]
However, the degree of resistance of the subject's mouth to tooth decay, that is, the risk of dental caries on the subject's teeth (generally referred to as Caries Activity Test) Had individual differences. Thus, for some people it may be sufficient to have an oral health check at a longer cycle, while for others it may be necessary to do an oral health check at a shorter cycle.
[0004]
On the other hand, if the subject has decided on a dentist to work with, it is possible to determine a certain degree of dental caries risk from past histories. It was difficult for even an experienced dentist to accurately judge the risk of caries from the subject only by visual inspection. Therefore, the dentist may prompt the patient to revisit within a short period of time, but the patient has had trouble responding to this.
[0005]
In addition, a patient who has requested treatment from a 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 has judged necessary. In other words, even if you look in your mouth with a mirror, it is difficult to find tooth cavities in the early stages. However, some patients postpone this.
[0006]
Although dentists point out the importance of improving the oral environment to patients, it is not possible to recommend them to reduce the risk of developing caries or dental caries that are not visible on the surface. was difficult.
[0007]
In addition, if the patient changes dentists due to relocation, the new dentist will create a new medical chart because he does not know the history of the patient, and will treat the patient's oral environment while treating. The situation that understands had occurred.
[0008]
The present invention has been made in consideration of the above circumstances, and has as its object that a subject accurately understands the risk of suffering dental caries of his / her own teeth and has sufficient To provide a dental caries risk assessment system, a dental caries risk assessment method and a tooth caries risk assessment program that can maintain the oral environment in the best condition after communication. is there.
[0009]
[Means for Solving the Problems]
To achieve the above object, a dental caries risk assessment system according to a first aspect of the present invention includes a measuring instrument for measuring the chemical properties of a specimen collected from the mouth of a subject, Risk evaluation function to evaluate the dental caries risk of the subject using the measured values of the chemical properties measured by the measuring device by having a database that records the evaluation reference data for evaluating the risk A terminal having an evaluation output function for outputting at least an evaluation of the dental caries risk, and a network for performing at least one of data input and output between the measuring instrument, the server, and the terminal. It is characterized by. (Claim 1)
[0010]
Therefore, the subject can measure the chemical properties of the specimen such as saliva collected from his / her mouth using the measuring instrument, and can evaluate the dental caries risk based on the measured chemical properties. As a result, it is possible to make an appropriate judgment of the own oral environment from the evaluation value of the dental caries risk, and to proceed with appropriate treatment when necessary. In other words, the dental caries risk, which has been difficult to identify in the past, can be clearly determined from the measured values of the chemical properties, and the necessity of treatment can be recognized from the evaluation.
[0011]
The measuring device can be arranged, for example, at a dental clinic, but may be distributed to the home of each subject, and the measuring device and the server may be connected by a network. Similarly, the server may be located in a dental office, but may be located in a management company that manages the server, and a plurality of dental offices may be able to connect to the server via a terminal and a network. The terminal is located at each subject's home and / or dentist. The terminal does not need to be a so-called network connection terminal, and is directly connected to the server, including an output device such as a display (including a display unit provided on the measuring device) and a printer, and an input device such as a keyboard and a mouse. It may be a device. The specimen is, for example, saliva of the subject, but may be a caries-causing substance such as plaque.
[0012]
In the case where the database has an electronic medical record that records tooth status transition data having measured value data of chemical properties of each subject (claim 2), measured value data of chemical properties related to the subject is provided. Is stored in the database as an electronic medical record, which can be used for treatment. In particular, when the dentist is changed, by presenting the contents of the electronic medical record, sufficient communication with the dentist can be achieved.
[0013]
In the case where the server has an electronic medical chart browsing function that enables the user to browse the state transition data of the tooth of the subject recorded in the electronic medical chart using the terminal (claim 3), the subject himself / herself You can read the electronic medical record and make an effort to keep the oral environment in good condition. On the other hand, by viewing the electronic medical record of the examinee who has visited the dentist as a patient, the transition of the oral environment can be confirmed even for a first-time visit patient, so that more accurate treatment can be performed. In addition, it is possible to provide each patient with appropriate advice such as instruction on tooth brushing, improvement in eating habits, and instruction on the type of dentifrice to be used so as to obtain resistance to tooth decay.
[0014]
While the electronic medical record has dental treatment history data of each subject as tooth state transition data, the server uses the statistics of measured value data and dental treatment history data recorded in a plurality of electronic medical records to perform the treatment. When an evaluation criterion creating / updating function capable of creating or changing the evaluation criterion data is provided (Claim 4), the evaluation criterion data indicating the relationship between the measured value of the chemical property and the evaluation value of the dental caries risk. Can be refined from the statistics of the actual data, and the risk of dental caries can be more accurately evaluated.
[0015]
In addition, it is possible to promote research in this field by adding a scholar who studies the risk of dental caries as a database administrator, and providing scholars with statistical data of measured value data and tooth condition transition data. it can. As the chemical properties related to the dental caries risk, at present it is conceivable to determine the pH and pH buffering capacity of saliva, but it is possible to measure other chemical properties in the future. That is, it is desirable that the types and values of the chemical properties used as the evaluation criteria can be changed or added as appropriate according to the opinion of a scholar who participates in the dental caries risk assessment system as a database administrator or an assistant.
[0016]
A terminal having an individual evaluation criterion input function for browsing the tooth state transition data recorded in the electronic medical record and creating or changing individual evaluation criterion data including an evaluation criterion adjusted for each subject is provided. In this case (claim 5), it is possible to obtain a more accurate dental caries risk by setting an evaluation criterion according to the personal condition of each subject.
[0017]
When the database records treatment guideline data that provides a guideline for treatment in accordance with the evaluation criterion (claim 6), it is easy to take an action corresponding to the evaluation value of the dental caries risk. Therefore, the use value of the dental caries risk assessment system is increased.
[0018]
In the case where the server has a treatment recommendation distribution function of distributing an appropriate treatment guideline for each subject using e-mail or the like in accordance with the dental caries risk assessment of each subject (claim 7). Thus, the subject can accurately know that his / her oral environment requires treatment, and can perform early treatment without losing time.
[0019]
When the treatment guide data includes subject treatment guide data for a subject and dentist treatment guide data for a dentist (claim 8), the subject understands in plain language. Easy treatment guidelines can be obtained, and dentists can obtain specialized and detailed medical guidelines, which can be used to improve skills. Also, when the subject visits the dentist as a patient, the dentist can feel reassured by the accurate and professional explanation and can promote communication with each other.
[0020]
When the database has an oral environment improving drug list (claim 9), the subject can easily select and purchase an appropriate drug for improving his / her oral environment. Also, a pharmaceutical company that manufactures the drug can promote the sale of the drug by registering the efficacy of each drug in the oral environment improving drug list.
[0021]
A case where the server has an examination appointment function of assigning a right to use a measuring instrument to each subject and receiving a dental caries risk assessment by accessing the subject's terminal via a network (claim In item 10), the subject can access the server via the network to evaluate the dental caries risk at his or her convenience, such as by renting a measuring instrument, Convenience is improved.
[0022]
The measurement of chemical properties using the measuring device may be performed at the subject's home by sending the measuring device from the administrator of the dental caries risk assessment system to the subject. The specimen may be measured by the administrator of the dental caries risk assessment system by sending the specimen collected from the mouth of the examiner to an inspection company or the administrator of the dental caries risk assessment system. Further, the chemical properties of the subject may be measured by visiting the test site provided by a dentist or an inspection company equipped with a measuring device.
[0023]
When the server has an evaluation distribution function of distributing the dental caries risk assessment of each subject to each subject using electronic mail or the like (Claim 11), the subject is evaluated Can be easily received, and an appropriate action can be taken according to the evaluation.
[0024]
When the database has a dentist list (claim 12), the dentist participating in the dental caries risk assessment system can be introduced to the subject. The subject can easily find a dentist who can be treated based on accurate judgment using the dental caries risk assessment system.
[0025]
When the server has a treatment reservation function for reserving treatment by a dentist on the dentist list by accessing from a terminal of the subject via a network (claim 13), the subject is a dentist It is possible to make an appointment for treatment without having to go to a dentist on the list or call this dentist, thereby improving convenience. A dentist can be referred to a patient by registering in the dental caries risk assessment system of the present invention.
[0026]
In the case where the server has a periodic inspection recommendation function of distributing a periodic inspection recommendation to the subject using an e-mail or the like according to the dental caries risk assessment of each subject (claim 14). Can recommend that the patient undergo a periodic examination at intervals adjusted to each subject, so that the subject does not have to perform the examination indiscriminately and does not forget the necessary examination.
[0027]
The method for evaluating dental caries risk according to the second invention measures the chemical properties of a sample collected from the mouth of a subject and evaluates the evaluation criteria for the dental caries risk based on the measured values of the chemical properties. By referring to the database that records the data, the measured values of the chemical properties are evaluated and output as the risk of dental caries of the subject, and the tooth having the measured values of the chemical properties of the subject is output.

[0030]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a diagram showing an example of a dental caries disease risk evaluation system 1 of the present invention.
In FIG. 1, 2 is a subject, 3 is a measuring device for measuring the chemical properties of a sample collected from the mouth of the subject 2, and 4 is the risk of dental caries of the subject 2 based on the measured chemical properties. The server 5 to be evaluated is a database stored in a storage unit in the server 4, for example, 6 is a terminal having an evaluation output function of the dental caries risk, 7 is the measuring device 3, the server 4, and the terminal 6 The Internet is an example of a network to be connected.
[0031]
The terminal 6 of the present example is composed of an information processing device such as a personal computer or a server, and includes a terminal 6A arranged at the home 8 of the subject 2 and a terminal arranged at each dental clinic 9 and operated by the dentist 10. 6B ... and a terminal 6C ... operated by an inspector 10 '... on the side of an inspection company 9' ... for measuring the chemical properties of a sample collected from the mouth of the subject 2 and conducting research on dental hygiene. The terminal 6X is disposed in the laboratory 11 and operated by a scholar 12 or the like. Each terminal 6A, 6B... Is disposed in various places connected by the Internet 7.
[0032]
On the other hand, the server 4 of the present example executes the dental caries disease risk evaluation program P, and is located in the database management company 13 that performs the dental caries disease risk inspection and manages the database 5. The information processing apparatus is operated by the administrator 14 of the database 5. However, the server 4 may be disposed in each dental clinic 9 or the inspection company 9 ', and each dentist 10 or the inspector 10' may manage this. In this case, it is also possible to use information processing devices (terminals 6B and 6C in this example) existing in each dental clinic 9 and the inspection company 9 'as the server 4.
[0033]
Further, it is needless to say that the database 5 does not necessarily need to be recorded in the storage unit in the server 4, and 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 caught by the frame of the dental clinic 9, and to evaluate 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 sample, and measures its pH and pH buffering ability as chemical properties. Various forms of the measuring device 3 are conceivable. For example, at the home 8 of the subject 2, a stick type configured to be connectable to a terminal 6A carried by the subject 2 by an interface of a predetermined standard such as USB. Of the measuring device 3A can be considered.
[0035]
The form of the measuring instrument 3 may be a stationary measuring instrument 3B configured to be connectable to terminals 6B, 6C,... Good. Further, a display unit 3a having a function of displaying measured values of chemical properties and a function of evaluating and outputting the risk of dental caries, such as the measuring devices 3B and 3C shown in FIG. You may.
[0036]
In addition, the measuring instrument 3 can be directly connected to the Internet 7 so that the measuring instrument 3B has a function as the terminal 6. Further, the measuring device 3 may be a measuring device 3C managed by the inspection company 9 '.
[0037]
The database 5 includes, 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, and at least measured values of chemical properties. Criterion data 16 indicating the relationship between the dentistry and the dental caries risk evaluation value, registered dentist data 17 indicating information on registered dentists cooperating with the true tooth caries risk evaluation system 1, and can be recommended It has oral environment improving drug data 18 indicating information on the oral environment improving drug.
[0038]
The state transition data 15A is, for example, measured value data 15a including a history of measured values of chemical properties of a sample collected from the mouth of the subject 2 or treatment content data unique to the subject 2 added by the dentist 10. It has treatment history data 15b of the teeth of the subject 2 and the like. In addition, the personal data 15B includes, for example, the address, name, age, gender, and contact information (may include an e-mail address) of the subject 2. Further, the individual evaluation criterion data 15C is an individual evaluation criterion adjusted for each subject 2 according to the situation.
[0039]
The evaluation criterion data 16 is not only data indicating the relationship between the measured value of the chemical property and the evaluation value of the dental carious disease risk, but also as treatment guideline data corresponding to the evaluation, for example, "Needs immediate treatment. It is possible to include the words "yes", "recommend diagnosis by a dentist", "recommend periodic diagnosis", and "currently there is no risk of developing dental caries". It is desirable that the treatment guide data separately store a general treatment guide 16a that will be easily understood by the subject 2 and a specialized treatment guide 16b that provides sufficient information to the dentist.
[0040]
Similarly, the evaluation standard recorded as the individual evaluation standard data 15C desirably also includes wording treatment guide data, and a general treatment guide easy for the subject 2 to understand and sufficient information for the dentist. It is desirable to separately memorize the specialized treatment guidelines that give
[0041]
In any case, in this example, the treatment guideline data for outputting the treatment guideline (text) corresponding to the evaluation is provided in a part of the evaluation criterion data. You can also.
[0042]
FIG. 2 is a diagram illustrating an example of the measuring device 3 (3A). 2, reference numeral 20 denotes a main body of the measuring instrument 3A, reference numeral 21 denotes a sensor unit, and reference numeral 22 denotes 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 includes an arithmetic processing unit 23 for obtaining a measured value of pH as an example of chemical properties of saliva measured by the sensor unit 21, and a display unit 24 for displaying, for example, the measured value obtained by the arithmetic processing unit 23. And an operation button 25 for the device user to operate the measuring device 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 used as a bottom surface. And a container 27 formed to contain saliva collected from the mouth of the subject 2.
[0044]
In addition, since the sensor surface 26 of this example shows an example in which the evaluation of the risk of dental caries is determined based on the measured value of pH, the sensor surface 26 is composed of an ISFET measurement electrode for pH measurement and a comparative electrode. Instead of this pH measurement, it is also possible to use an ORP measurement or another chemical property such as the concentration of other ions such as calcium or the amount of protein as a criterion. That is, by attaching the 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 that a plurality of chemical properties are measured on the sensor surface 26, and the chemical properties are comprehensively determined to determine the dental caries risk. In addition, when measuring other physical property parameters of the solution such as ORP and calcium ions, it goes without saying that the configuration of the electrodes on the sensor surface 26 is changed. In any case, the measured value S of each chemical property measured by the sensor surface 26 ₀ 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 28. The lid 28 is rotatable by a hinge 29, and is fitted in a watertight manner to the edge of the container 27 with the lid 28 closed. And a lid body 30 having an opening 28b formed in the upper portion of the container 27, and the opening 28b can be completely closed by slidably engaging with the lid body 30. The movable body 31 is formed. In order to prevent leakage of the saliva contained in the container 27, it is desirable that the saliva can be completely closed.
[0047]
The subject 2 shown in FIG. 1 accesses the server 4 via his / her terminal 6A and makes an application for the use of the dental caries risk assessment system 1 so that the subject 2 is stored in the database 5. In addition to the creation of the electronic medical record 15, the measuring device 3 can be sent from the inspection company 9 ′. Here, when creating the electronic medical record 15, an accurate medical record 15 is created by interrogating the past dental examination history of the subject 2 on the web or sending documents. At the same time, the ID and password of the subject 2 that are required when using the dental caries disease risk evaluation system 1 of the present invention in the future 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 receiving the use application, and assigns the usable measuring device 3A to the subject 2. The transmission function has an examination appointment function that enables reception of the dental caries disease risk assessment that assigns the right to use the measuring device 3A to the subject 2. Note that this application for use is not limited to application via the Internet 7, and may be performed 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 measuring instrument 3A reaches the home 8, the subject 2 connects the measuring instrument 3A to the terminal 6A and measures the chemical properties of his or her saliva as a specimen. FIG. 3 is a diagram illustrating 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 disease risk assessment system 1 of the present invention will be described with reference to FIG. However, the dental caries disease risk evaluation system 1 of the present invention does not limit the configuration of the measuring device 3 and the method of measuring chemical properties described 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 checked, for example, on a scale (not shown) provided on the syringe 35, and only the amount necessary for measurement is collected. Although this amount depends on the capacity of the sensor unit 21, when forming the sensor surface 26 using ISFET as in the example shown in FIG. 2, it is sufficient to collect, for example, 0.5 mL or more.
[0051]
Next, as shown in FIG. 3 (B), the collected saliva 36 is checked on a scale or the like provided on the syringe 35, and just 0.5 mL is dropped on the sensor surface 26 and stored in the container 27. At this time, the saliva 36 may be stored with the lid main body 31 opened, or the saliva 36 may be stored through the opening 28b by opening the movable body 31 with the lid main body 31 closed. Note that the present invention does not limit the amount of saliva 36 used for evaluating the dental caries risk, and the measurement can be performed using a smaller amount of saliva 36 depending on the performance of the sensor surface 26.
[0052]
Next, the pH of the saliva 36 is measured by operating the measurement button 25. Note that the power supply of the measuring instrument 3A is supplied from the terminal 6A side as in this example, so that the operation of the power supply can be simplified without the power supply operation. Needless to say. Further, the first pH measurement may be automatically started with the dripping of saliva 36 onto the sensor surface 26.
[0053]
Then, when the measurement of the pH is completed, the arithmetic processing unit 23 stores the pH value, and then is sent from the inspection company 9 'to the apparatus user by attaching it to the measuring instrument 3A by an alarm sound or display or the like. Output a message prompting you to add the acid.
[0054]
FIG. 3C is a diagram showing a procedure for mixing a predetermined ratio of acid 37 with saliva 36. The acid 37 to be mixed here is, for example, a 0.1 mol / L hydrochloric acid aqueous solution, and in this case, 10 μL is measured and injected using a desired chemical 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, the container 27 can be hermetically closed by completely closing the lid 28, and when the measuring instrument 3A is well shaken and stirred to sufficiently mix the acid 37 with the saliva 36, leakage of the saliva 36 is prevented. be able to. Further, in order to sufficiently exert the pH buffering ability of the saliva 36, after the acid 37 is dropped, the pH measurement can be performed for a second time after being left for a predetermined time (about 30 seconds to 1 minute).
[0056]
Preferably, the idle time is set by a program executed by the arithmetic processing unit 23. That is, by outputting a message prompting to perform the second pH measurement by 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, for example. 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 instrument 3A outputs to the user of the apparatus such that 10 μL of the aqueous hydrochloric acid solution is dropped again, and the above-mentioned FIGS. 3 (C) and 3 ( The process of D) is repeated. In this way, the dropping of the aqueous hydrochloric acid solution is repeated three times, and the change in the pH value at that time is measured, whereby a total of 30 μL of the aqueous hydrochloric acid solution is obtained for 0.5 mL of saliva 36 (0.000006 for 1 mL of saliva). The change in pH value when a gram equivalent of the acid 37) is mixed in a predetermined ratio is measured.
[0058]
In addition, as in this example, the acid 37 is added to the saliva 36 at a rate of 0.000002 gram equivalent to 1 mL of the saliva in three portions, and the change in pH at that time is measured. It is possible to more accurately determine the pH buffering capacity. However, it is needless to say that a predetermined ratio of the acid 37 for obtaining the final result may be dropped at a time. In this case, the time required for the measurement can be reduced.
[0059]
In addition, in this example, an example is shown in which the acid 37 is dropped on the saliva 36 manually so as to clarify the method for measuring the pH buffering capacity, but the present invention is not limited to this point. That is, the measuring device 3A is programmed to automatically mix an appropriate amount of the acid 37 at an appropriate timing from the acid container (not shown) of the measuring device 3A, so that the operation by the subject 2 is reduced. And the physical properties can be easily measured.
[0060]
Then, measured values S such as pH and pH buffer capacity ₀ Is stored in the database 5 in the server 4 via the terminal 6A and the Internet 7, and the server 4 refers to the evaluation standard data 16 based on the dental caries disease risk evaluation program P and measures the measured values of each chemical property. S ₀ Of dental caries risk S ₁ , 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 mol / L hydrochloric acid aqueous solution was dropped and mixed three times in 10 μL portions to 0.5 mL saliva collected from 15 subjects 2. It is. The evaluation criterion data 16 is a relation obtained based on such measured values, and the evaluation is recorded as a table, for example.
[0062]
Specifically, saliva 36 having a pH of, for example, 5.7 or more measured in a state in which 30 uL of an aqueous hydrochloric acid solution is dropped can be statistically determined to have a low risk of dental caries (that is, LEVEL0). When the pH is, for example, 5.4 or more and 5.7 or less, it can be determined that the risk is moderate (LEVEL1), and when the pH is less than 5.3, the risk is high (LEVEL2). Note that this range does not limit the present invention, and does not limit expressing the dental caries risk in three stages.
[0063]
In addition, as shown in FIG. 4, individual differences occur in the appearance of the pH buffering capacity when the acid 37 is dropped. Then, by using the dental caries disease risk assessment 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 subject 2 Can be compared or updated to more realistic evaluation criterion data 16. On the other hand, based on the personal history of each subject 2, personal evaluation criterion data 15C that takes into account its unique tendency can also be created.
[0064]
The creation and updating of the individual evaluation criterion data 15C can be performed, for example, by inputting from the terminal 6B by the dentist 10 who has examined the subject 2 as a patient and storing it in the database 5. This makes it possible to create more accurate personal evaluation reference data 15C based on the skills of the dentist 10. At the same time, additional data, such as wording treatment guidelines, may be added by the dentist 10 or the like.
[0065]
