2. Description of the Related Art Conventionally, periodontal disease was considered to be an adult disease peculiar to the elderly, but due to changes in dietary habits, the presence of juvenile periodontitis that has developed since the teens has been confirmed in recent years. There is. Periodontal disease progresses chronically without subjective symptoms, so detection is likely to be delayed, and it is common to see a doctor after the terminal symptoms occur. Therefore, early detection and early treatment are particularly important for preventing periodontal disease.

Periodontal disease belongs to two major oral diseases together with dental caries (cavities) and is caused by periodontopathic bacteria such as Profilomonas gingivalis bacterium and Actinobacillus actinomycetecomitans bacterium to cause gingivitis. It is divided into periodontitis. Of these, gingivitis is an inflammation of only the gingiva and is relatively easily cured by mechanical treatment such as brushing, while periodontitis is a causative agent of not only the gingiva but also the alveolar bone supporting the teeth. It is affected by and can cause loss of teeth in severe cases. Generally, periodontal disease is diagnosed by comprehensively evaluating clinical findings such as swelling of the gingiva, depth of periodontal pocket, and bleeding condition visually observed by a dentist.

On the other hand, periodontal pathogens produce odorous substances such as ammonia, methyl mercaptan and indole.
It contributes to bad breath. The concentration of methyl mercaptan is higher than that of hydrogen sulfide, so that the intensity of halitosis and the methyl mercaptan / hydrogen sulfide ratio are proportional to the severity of periodontal disease. Therefore, a correlation is established between the intensity of bad breath and periodontal disease. A gas chromatograph capable of measuring an extremely small amount of odorous components is an effective means for diagnosing periodontal disease from halitosis.

[0005]

However, since the above-mentioned gas chromatograph is expensive and complicated to operate, it is limited to use in a dental university hospital or a part of dental clinics in which many specialists are enrolled. There is. For this reason, it is difficult to easily grasp whether there is a possibility of periodontal disease or the degree of progression of periodontal disease, even if general attention is paid to oral diseases. There is also a demand to easily and objectively grasp the degree of one's own bad breath in order to suppress the bad breath.

In view of the above problems, the present invention provides a pre-oral examination system for oral cavity, a pre-examination method for oral cavity, a recording medium and a program recording the method, which can easily determine the degree of progression of periodontal disease and bad breath. Is an issue.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a periodontal disease preliminary examination system to which the present invention is applicable will be described below with reference to the drawings.

(Structure) As shown in FIG. 1, on the Internet 5, a packet center 3 for connecting packet communication with the mobile phone 1 to the Internet 5 via a ground relay station 4, and a breath sent from the mobile phone 1. A periodontal disease preliminary examination site 6 for conducting a preliminary examination for periodontal disease of the user based on data or the like is connected. Further, the Internet 5 can be connected to the personal computer 8 of the dentist via the provider 7.

The mobile phone 1 can be connected to the breath measuring device 2 via a connection cable 9. As shown in FIG. 2, the breath measuring device 2 includes a breath filling chamber 21 having an inner wall processed with Teflon (registered trademark) for filling breath of a user, and four types of semiconductor gas sensors 23 connected to the breath filling chamber 21. It has a sensor chamber 22 housed therein. The inner wall of the sensor chamber 22 is also the exhalation filling chamber 21.
It is treated with Teflon as well as.

The expiratory filling chamber 21 includes an electromagnetic valve V ₁
Is connected to one end of the exhalation guide tube TB via. To the other end of the expiration guide tube TB, a mouthpiece MP which is disposable and integrated with the expiration reservoir is detachably attached. The sensor chamber 22 has a suction pump P in communication with the opposite side of the expiratory filling chamber 21. Therefore, the exhalation of the user is measured by the exhalation measuring device 2 through the exhalation guide tube TB and the mouthpiece MP integrated with the exhalation reservoir.
Introduced inside, electromagnetic valve V1, exhalation filling chamber 2

A semiconductor gas sensor of 10/9 and P40 / 1 was used.

As shown in FIG. 3A, each semiconductor gas sensor 23 has a cylindrical n-type oxide semiconductor (hereinafter referred to as n-type semiconductor S) obtained by sintering fine particles of tin oxide. Since the gas detection by the semiconductor gas sensor 23 depends on the adsorption / desorption phenomenon on the surface of the n-type semiconductor S, the n-type semiconductor S is heated by the heater coil H in order to increase the gas adsorption rate on the surface. The current flowing through the n-type semiconductor S flows through the junction of fine particles of tin oxide, and when the n-type semiconductor S is in clean air, the adsorption of oxygen on the surface of the n-type semiconductor S causes the potential of the particle interface. The n-type semiconductor S has a high resistance value R because the barrier becomes high and prevents movement of electrons.
s is shown. When the reducing gas reaches there, adsorption and oxidation reaction of gas molecules on the surface of the n-type semiconductor S occur, the potential barrier is lowered, and electrons are easily moved. Therefore, the n-type semiconductor is changed depending on the concentration of the sensitive gas. The resistance value Rs of S becomes small (see FIG. 3B). Therefore, by continuously extracting the magnitude of the resistance value Rs of the n-type semiconductor S as the output voltage Vout, time series data of the specific resistance value according to the gas concentration can be obtained.

The chamber cleaning section 24 includes a distilled water layer for controlling the humidity of the carrier gas, a calcium chloride layer for removing carbon dioxide, and an activated carbon layer for removing moisture and odor components.

The exhalation measuring instrument 2 can operate the control unit 26 for controlling the whole exhalation measuring instrument 2, the commercial power source, the suction pump P of the exhalation measuring instrument 2, the electromagnetic valves V ₁ and V ₂ , and the control unit 26. It has a power supply unit 25 for converting into a DC voltage. The control unit 26 includes an expiratory data generation section that generates expiratory data, a control section that determines whether or not the expiratory data is appropriate, and causes the mobile phone 1 to transmit the expiratory data and the like to the periodontal disease preliminary examination site 6 and an interface. It is composed of sections. The exhalation data generation section
It has an operational amplifier (OP) that amplifies the output voltage Vout output from both ends of the load resistor R _L , and an A / D converter that converts an analog signal output from the operational amplifier into a digital signal at a sampling rate of 10 Hz. The expiration data generated by the expiration data generation section is temporarily stored in the RAM in the control section. The control section has a CPU, a ROM, a RAM, and an internal bus connecting these.

A display unit (not shown) composed of three LEDs of green, orange, and red is disposed above the breath measuring device 2. These LEDs are used to instruct the user to start exhalation, as will be described later.

As shown in FIG. 4, the periodontal disease preliminary examination site 6 includes an armed zone 61 such as a firewall for arming against unauthorized access from the external net. The Internet 5 is connected to a bus-type LAN 62 set up in the periodontal disease preliminary examination site 6 through the armament zone 61. In the LAN 62, a WWW server 66 that communicates with the mobile phone 1 and the personal computer 8, member data such as the name and age of a member (who registered later among users), mail address, breath data, etc. are stored. A database server 67 and an artificial neural network (hereinafter abbreviated as ANN) are transplanted, and the expiration data and the like stored in the database server 67 are read out to perform a preliminary examination for the periodontal disease of the user (member). Analysis server 68, WEB server 6 that stores the homepage of the periodontal disease preliminary examination site 6
4. Reservation server 65 that supports members' visit reservations made to dentists and after-sales services provided by members to dentists. Contract dentists were visited by monthly flat-rate fees and visit reservations. Sometimes, a charge management server 63 for adding points to members while connecting to the flat-rate membership fee to calculate and charge the charge amount is connected.

(Operation) First, the operation of the breath measuring device 2 will be described. It is assumed that the mobile phone 1 and the breath meter 2 are connected in advance by the connection cable 9.

[0025] When the power of the breath measurement device 2 is turned on, CPU of the control unit 26 (hereinafter, simply. As CPU) opens the solenoid valve _{V 2} is closed the solenoid valve _{V 1,} a predetermined time (e.g., 30 Second) By operating the suction pump P,
Residual gas in the breath-filled chamber 21 and the sensor chamber 22 is removed (exhausted from the breath measuring device 2) by the carrier gas generated in the chamber cleaning unit 24, and heated by each heater coil H to produce four types of n-type semiconductors S. Clean the surface of. During this period, the breath measuring device 2 cannot perform the breath measurement, and thus the red LED (not shown) is turned on to prompt the user to prepare to blow the breath. When the predetermined time has elapsed, the electromagnetic valve V ₁ is opened and the electromagnetic valve V ₂ is closed. This completes the preparation for exhalation measurement.

Next, in order to inform the user of the start of exhalation measurement, the red LED is turned off and the green LED not shown is shown.
Is turned on (hereinafter, this time is referred to as the start of exhalation measurement). The suction force of the suction pump P is equal to that of the exhalation filling chamber 2
1 and the flow velocity of the air flowing in the sensor chamber 22 is 20
It is adjusted to be 0 ml / min. The user blows the exhaled air through the mouthpiece MP which is integrated with the exhalation reservoir for about 2 seconds in response to the lighting of the green LED. The exhaled blown air is filled in the expiratory filling chamber 21 through the expiratory guide tube TB by the suction force of the suction pump P,
Further, it is introduced into the communicating sensor chamber 22. C
PU is the electromagnetic valve V 2.5 seconds after the start of exhalation measurement.
1 is closed and the electromagnetic valve V2 is opened. As a result, the carrier gas is supplied from the chamber cleaning section 24 to the expiratory filling chamber 21. In addition, in the present embodiment, the standard intake time of exhalation is set to 2 seconds, but it is difficult for the user to accurately measure 2 seconds, and from the lighting of the blue LED until the exhalation is exhaled. In consideration of a slight delay and the volume of the exhalation guide tube TB, allow 0.5 seconds after the blue LED lights up for 2.5 seconds and the standard exhalation time of 2 seconds. There is. The CPU stops the suction pump P 60.5 seconds after the start of the exhalation measurement, and turns on an orange LED (not shown) to urge the user to wait.

Further, the CPU causes the above-mentioned four kinds of semiconductor gas sensors 23 to perform the predetermined time (time required for cleaning).
In addition to this, the operating power supply Vc is supplied for 60.5 seconds from the start of the breath measurement (see FIG. 3A). By applying the operating power supply Vc a predetermined time before the start of exhalation measurement, the heater coil H reaches a predetermined temperature, and the four types of semiconductor gas sensors 23
The (n-type semiconductor S) is in a stable state. The output voltage Vout from both ends of the four types of semiconductor gas sensors 23 is amplified by an operational amplifier and input to each A / D converter. C
The PU operates each A / D converter for 60 seconds from the start of exhalation measurement.

This 60 seconds from the start of exhalation measurement is the exhalation data measurement time. The exhalation data output from each A / D converter is stored in the RAM of the control section (hereinafter simply referred to as R
It is called AM. ). The number of breath data per semiconductor gas sensor 23 stored in the RAM is 10 since the sampling rate is 10 Hz and the operation time is 60 seconds.
Hz × 60 seconds = 600 (pieces). Therefore, the RAM temporarily stores the exhalation data number 2,400 (pieces) for four types of semiconductor gas sensors 23.

Next, the CPU determines whether or not the expiration data stored in the RAM is appropriate as the expiration data for the periodontal disease preliminary examination. As shown in FIG. 8A, in the exhaled breath data output from the semiconductor gas sensor PA2, when the suction time is plotted on the horizontal axis and the specific resistance value is plotted on the vertical axis, in a typical case, it is within the breath measurement time. It is recognized that the resistivity has a maximum value. When the specific resistance value and the expiration measurement time are generalized, as shown in FIG. 9, the specific resistance value gradually increases from the start of the expiration measurement and reaches the maximum value at the end of the expiration measurement time, but the specific resistance value is a relative value. In less than 5 (curve of (1)), the specific resistance value increases from the start of exhalation measurement and reaches the maximum value in the latter half of exhalation measurement time (curve of (2)), in the first half of exhalation measurement time. A pattern in which the specific resistance value decreases after reaching the maximum peak (curve of (3)), and a pattern in which the specific resistance value decreases after reaching the maximum value in a short time after the start of exhalation measurement (curve of (4)) It can be classified into four types.

Therefore, in order to judge whether or not the data is appropriate as the expiration data for the periodontal disease preliminary examination, it is necessary to pay attention to the specific resistance value and judge whether or not these characteristics are present. In the present embodiment, in order to make this determination, when the maximum specific resistance value of the semiconductor gas sensor PA2 exceeds 2 in relative value (see FIG. 9), it is determined that the user has normally performed the exhalation measurement, and the orange LED is turned on. It is turned off and the green LED is turned on to inform the user that the breath measurement is normally performed, and it is determined that the breath measurement cannot be normally performed when the maximum specific resistance value of the semiconductor gas sensor PA2 is 2 or less in relative value. The orange LED is turned off and the red LED is turned on to notify the user that the exhalation measurement needs to be performed again. In this case, the process returns to the cleaning process before the start of exhalation measurement described above.

Next, the CPU controls each semiconductor gas sensor 23.
The maximum specific resistance value is searched for each piece of expiration data, and the expiration measurement time when the maximum specific resistance value is obtained is calculated. Since the exhalation data is sampled every 10 Hz, the exhalation measurement time when the maximum specific resistance value is obtained can be obtained from the order of the exhalation data. Next, the CPU calculates the differential (difference) value for the breath data for each semiconductor gas sensor 23, searches for the maximum differential value, and calculates the breath measurement time when the maximum differential value is obtained. In FIG. 8B, the vertical axis is the differential value,
The abscissa indicates the expiration measurement time, and this calculation concept is shown.

The CPU creates the expiration data of each semiconductor gas sensor 23 thus obtained as user measurement data. That is, the user measurement data includes the maximum specific resistance value of the semiconductor gas sensor PA2, the expiration measurement time, the maximum differential value, the expiration measurement time, and the semiconductor gas sensor T50 / 3.
Maximum specific resistance value, the expiration measurement time, the maximum differential value, the expiration measurement time, the maximum specific resistance value of the semiconductor gas sensor P10 / 9, the expiration measurement time, the maximum differential value, the expiration measurement time, the semiconductor gas sensor P40 / 1 16 data of the maximum specific resistance value, the expiration measurement time, the maximum differential value, and the expiration measurement time. When the CPU finishes creating the user measurement data, the 2,400 (pieces) of exhalation data are no longer needed and are deleted from the RAM. During the generation of the user measurement data, the CPU lights up the orange LED in addition to lighting up the green LED to notify the user that the calculation is in progress.

When the user measurement data creation is completed, the CPU turns on only the orange LED. Next, the CPU requests access to the periodontal disease preliminary examination site 6, further requests input of whether or not the member is a registered member, and when the determination is affirmative, prompts the mobile phone 1 to input the member ID and password, Wait for input. On the other hand, when the determination is negative, the mobile phone 1
Enter the user's age (numerical value), sex (female 0, male 1), risk factor (user 0 not taking or smoking, user 1 taking or smoking 1) and email address on the display of Instruct and wait for input. The user operates the cursor movement button and the ten-key pad of the mobile phone 1 to input these data (hereinafter referred to as user attribute data) necessary for the preliminary examination at the periodontal disease preliminary examination site. CP
When the confirm button is pressed, U determines whether or not any of these user attribute data is null, and when the determination is negative, prompts for input of null data and waits for input.
When the determination is affirmative, the cellular phone 1 is caused to transmit periodontal disease preliminary examination data composed of user attribute data and user measurement data to the periodontal disease preliminary examination site 6. CPU
When the transmission is completed, turns off the orange LED (turns off all the LEDs) and notifies the user that the connection cable 9 connecting the mobile phone 1 and the breath measuring device 2 can be unmounted. This completes the user's breath measurement work. The user can access the periodontal disease preliminary examination site 6 (WEB server 64) by the mobile phone 1, and can download or update the Java program for operating the CPU of the control unit 26 free of charge.

Next, the operation of the periodontal disease preliminary examination site 6 will be described with reference to the flowchart.

As shown in FIG. 5, the WWW server 66 is
The host processing routine is executed by an access from a user (member) or a dentist as described later. First, at step 102, it is judged from the received command of the Java program whether or not the member is registered, and when the judgment is affirmative,
In step 104, the member registration process for passing the process to the WEB server 64 is executed, and the host processing routine ends.

The user connects to the WWW server 66 with the mobile phone 1 having the Internet function and opens the member registration page linked to the home page. The WWW server 66 passes the processing to the WEB server 64 and allows communication between the mobile phone 1 and the WEB server 64. Mobile phone 1
On the display, a registration screen for inputting the user's name, current address, sex, date of birth, smoking, presence / absence of medication, mobile phone number, mail address, and zip code as member attribute data is displayed. The user sequentially inputs by key operation on this registration screen, and the WEB server 64
Send to. The WEB server 64 determines whether or not all of these data have been entered, and when the determination is negative, prompts the user to re-input, and when the determination is positive, sends a registration screen for prompting the user to input the password. , Prompt user to register password. The WEB server 64 issues a member ID after confirming the input of the password, and transmits a Java program that enables a later-described visit appointment, etc., to the mobile phone 1. From this, the user's membership registration is completed. The WEB server 64 causes the database server 67 to store the member attribute data, the user ID and the password.

If a negative decision is made in step 102,
In the next step 106, it is determined whether or not the periodontal disease preliminary examination is performed, and when the determination is affirmative, in step 108,
It is judged whether or not the member is a member, and when the judgment is negative, after the provisional ID is given, the database server 67 is caused to store the data for periodontal disease preliminary examination together with the provisional ID, and the analysis server 68 is notified of the provisional ID, The host processing routine ends. On the other hand, when the determination is affirmative, the database server 67 stores the periodontal disease preliminary examination data, and the analysis server 68 stores the membership I data.
Notify D and terminate the host processing routine.

As shown in FIG. 6, in the analysis server 68,
An analysis processing routine is executed that determines the degree of progression of periodontal disease from the calculation result of the ANN and notifies the user (or member) of the result by email.

In this analysis processing routine, first, in step 202, it is judged whether or not there is an object to be processed by referring to the list of member IDs or provisional IDs notified from the WWW server 66, and the result is negative. If yes, wait and step 2 if positive
The following processing is executed.

At step 204, the member ID or temporary ID of the user to be processed is acquired from the list, and at the next step 206, periodontal disease preliminary examination data is acquired from the database server 67 using the member ID or temporary ID as a key. . In the case of a member, unlike the user, the user attribute data is not received, so the database server 6
Data of age, sex, and risk factor corresponding to the user attribute data is also acquired from the member attribute data stored in 7.

Next, in step 208, the periodontal disease correlation value C of the user (member) is calculated by the ANN. As shown in FIG. 7, the ANN has 20 input layers and the same number of input layers as 2 input layers.
It is composed of a three-layer structure having zero intermediate layers and one output layer. In the input layer, in addition to age A, sex S, risk factor R (not shown in FIG. 7) that make up the periodontal disease preliminary examination data, 16 user measurement data D, and four types of semiconductor gas sensor PA2. A total of 20 pieces of data of PA2 feature values obtained by digitizing the features of the waveform pattern (see FIG. 9) are input, and a periodontal disease correlation value C of 0 to 1 indicating the degree of periodontal disease progression is output from the output layer. Is output. A of this embodiment
NN has a correlation coefficient between the periodontal disease correlation value C of 0 to 1 output from the output layer and the degree of periodontal disease progression of 0.9 due to learning (backpropagation) up to a mean square error of 0.0005.
It is configured to have 7 or more. Therefore, in step 208, the PA2 feature value and the above-mentioned 19 periodontal disease preliminary examination data are input to the input layer of the ANN,
The parameters of the neurons between the input layer and the intermediate layer are calculated, and the parameters of the neurons between the intermediate layer and the output layer are calculated to calculate the periodontal disease correlation value C from the output layer.

In the next step 210, it is determined (selected) to which division the periodontal disease correlation value C of the user (or member) corresponds in advance. As shown in FIG. 10, in this determination, when the periodontal disease correlation value C is 0 ≦ C ≦ 0.3, it is not periodontal disease (healthy), 0.3 <C <0.
It is determined that the periodontal disease is suspected when 7 and the possibility of periodontal disease is high when 0.7 ≦ C ≦ 1.0.

Next, in step 212, it is determined whether or not the member is a member based on whether or not the user has a member ID. If the determination is negative, the process proceeds to step 220. If the determination is affirmative, the next step 214 is periodontal disease. It is determined whether the correlation value C is 0.3 or less. When the determination is affirmative, the process proceeds to step 220. When the determination is negative, that is, when periodontal disease is suspected or the possibility is high, the user has three dental clinics. Selection is made from among the dentists stored in the database server 67 in order to recommend doctors.

By the way, the dentist connects to the WWW server 66 by the personal computer 8, opens the dentist contract page linked to the home page, and is registered at the periodontal disease preliminary examination site 6 through the following procedure. Can become a dentist (contract dentist). In the dentist contract page, information on system contents, use of dentist name and dental clinic name by the periodontal disease preliminary examination site 6, provision of priority acquisition right of patient to dentist in specified area, periodontal disease Regarding the communication medium with the patients referred to by the preliminary examination site 6 to be the periodontal disease preventive examination site 6 only, the admission fee, the monthly fee, and the fee for acquiring the patients referred to by the periodontal disease preliminary examination site 6 Notify the dentist of the contract details, and if the dentist understands, display the dentist registration page. On the dentist registration page, the name of the dental clinic,
Director name, address, date of birth, phone number, fax number,
Registration to enter information such as e-mail address, credit card number, expiration date, transportation for visits, dentist's specialty, diagnosable day and time for patients referred to by the periodontal disease preliminary examination site 6 The screen is displayed. On this registration screen, the dentist wishing to register sequentially inputs these registration attribute data by key operation, and the WEB server 6
Send to 4. The WEB server 64 determines whether or not all of these data have been input, prompts the dentist to re-enter in the case of negative determination, and displays a registration screen for prompting the dentist to enter the password in the case of positive determination. Send and encourage dentist to register password. WEB server 64
Issues a dentist ID after confirming the password input. From this, most of the dentist registration is completed. W
The EB server 64 causes the database server 67 to store the registration attribute data, the dentist ID, and the password. In addition, the dentist who wishes to register is sent to the operator of the periodontal disease preliminary examination site 6 by mail or receipt of a copy of a certificate proving that he / she is a dentist. When the credit is confirmed to be a doctor, the operator is WE
From the B server 64, the dentist ID of the dentist wishing to register
The recommended information is added to the predetermined field of the database server 67 based on the
The Java program that allows the W server 66 to connect is transmitted to the personal computer 8. Upon completion of the operation by the operation subject, the dentist wishing to register becomes a dentist recommended from the periodontal disease preliminary examination site 6, that is, a contract dentist.

Therefore, in step 216, among the contracted dentists stored in the database server 67, for example, three dentists having a postal code close to the postal code of the member by referring to the postal code of the member, and the later-described In order to do so, the dentists with a good reputation in a certain area are selected as recommended dentists, and the dentist IDs of the selected three recommended dentists are recommended dentists of the member of the database server 67. It is added to the field as attribute information.

In the next step 218, in order to give the result of the periodontal disease preliminary examination of the member who made the appointment for hospital visit as preliminary information to the dentist who made the appointment for visit later, as shown in FIG.
Create dentist data as a graph as shown in. The data for the dentist is step 20 in addition to the graph.
Information such as the periodontal disease correlation value C calculated in 8, the age, sex, and risk factor of the member who made the appointment for the visit is created in PDF in A4 size.

At step 220, user reply data (message) is selected to inform the user (member) of the result of the periodontal disease preliminary examination. Periodontal disease correlation value C is 0.3
In the following cases, for example, the message "No suspicion of periodontal disease is seen. Please receive periodical periodontal disease preliminary examination" is selected, and the periodontal disease correlation value C is 0. In the case of 3 to 0.7, for example, in addition to the message "The periodontitis is suspected, but it is considered to be curable by brushing etc. because it is a little." If you are not a member), "We recommend you to register as a member. You can register for free and get information about your nearest dentist or a reputable dentist. For more information, please visit our website. . "Was selected,
If the user is a member, information (name, address, etc.) about the three recommended dentists selected in step 216 is added. When the periodontal disease correlation value C is 0.7 or more, for example,
In addition to the message that "I am likely to be a serious patient and need to visit the hospital as soon as possible", the user's request is to "Get information from the nearest dentist or a reputable dentist by registering as a member." For more information, please refer to the website. "If you are a member, information (name, address, etc.) about the three recommended dentists selected in step 216 will be added. .

Next, in step 222, step 104
Alternatively, in step 108, the mail address of the user (member) stored in the database server 67 is acquired, and a transmission process for transmitting the message selected in step 220 from the WWW server 66 to the mobile phone 1 is executed and then step 20
Return to 2. The WWW server 66 sends a mail to the user (member) according to the instruction from the analysis server 68 (see also step 114 in FIG. 5). This allows the user (member) to know the degree of progress of his or her periodontal disease.

On the other hand, if a negative judgment is made in step 106 of FIG. 5, it is judged in the next step 110 whether or not it is a hospital appointment, and if a positive judgment is made, the process is passed to the reservation server 65 in step 112. The visit reservation is executed and the host processing routine ends.

When the reservation server 65 is accessed by the member, after being authenticated by the member ID and the password, the reservation server 65 prompts the user to input the credit card number and the expiration date when making the first hospital appointment, and in step 216, the database server 67.
Reservation screen that reads out the dentist IDs of the three recommended dentists stored in the table, and lists the information such as transportation to visit the recommended dentists to the three recommended dentists, available days for diagnosis, and time zone, etc. Is transmitted to the mobile phone 1. The credit card number and the expiration date of the member, which were input at the time of the first visit appointment, can be obtained from the appointment server 65 to the database server 6
7 is notified and stored in the database server 67.
The member selects one dentist who he / she wants to make a visit appointment by considering the recommended dentist's diagnosable time, etc. by the Java program, and inputs the desired visit date and the desired time to enter the periodontal disease preliminary examination site 6 Send to.

The reservation server 65 determines whether or not all the predetermined items (dentist name, desired date and desired time) have been entered. If the determination is negative, the member is prompted to input, and if the determination is affirmative. After confirming (examination) the credit of the credit card, it is determined whether or not the day and time of the day that the dentist has registered can diagnose. When the desired date and desired time of the member correspond to the day and time of the day that can be diagnosed, the dentist can refer to the data additionally added to the fields of the day of the week and the time of day that can be diagnosed by the database server 67. It is judged in advance whether or not the member cannot visit the hospital for some reason such as illness or travel. If the result is negative, a message indicating that the appointment for the hospital visit has been sent to the mobile phone 1, The diagnosis reservation date, time zone and dentist ID are added to the reservation fields of the member of the reservation server 65, and the diagnosis reservation date, time zone and member ID are reserved server 65.
Add to the reservation field of the dentist. As a result, the member is able to make a visit appointment, and at a later date, he / she can access the periodontal disease preliminary examination site 6 to confirm his / her visit appointment. On the other hand, when the determination is affirmative, the member is notified of the date after the date when the condition in which the member cannot visit the hospital is released. The member refers to the dentist's diagnosable date notified to him again and makes a new reservation or a visit appointment to another recommended dentist in the same manner as above. In addition, since the change of the visit appointment is allowed up to one day before, the member can access the appointment server 65 of the periodontal disease preliminary examination site 6 to change or cancel the appointment of the visit as necessary. .

The reservation server 65 transmits the fact that there is a visit reservation to the personal computer 8 and the fax of the dentist via the WWW server 66. Therefore, registration to the periodontal disease preliminary examination site can acquire unspecified patients, which can be a business for the dentist. Further, the reservation server 65 allows only the dentist concerned to download the dentist data created by the analysis server 67 in step 216. For this reason, the dentist prints a PDF indicating the degree of periodontal disease of the patient who has made a reservation through the reservation server 65 in advance as necessary, and refers to and grasps the PDF, so It is possible to obtain sufficient preliminary knowledge of.

The member deposits a predetermined amount (for example, 1,000 yen) at the time when the visit reservation is made. The reservation server 65 notifies the charge management server 63 of this deposit. If you did not come to the hospital even if you made a reservation,
The charge management server 63 charges the member for the above-mentioned predetermined amount. This charge is the only charge that the periodontal disease preliminary examination site 6 charges the member.

When the member who made the appointment for visiting the hospital accesses the periodontal disease preliminary examination site 6 with the mobile phone 1 after the examination by the dentist and selects the questionnaire, the WWW server 66 passes the processing to the appointment server 65 (FIG. 5). 114). In the questionnaire screen, in addition to the name of the dental clinic and the name of the dentist whose information is provided from the reservation server 65, in order to evaluate the dentist who has been examined from the viewpoint of the patient, the reception of the dental clinic, the reception of the dentist, the dental clinic. Evaluation information about the health of the doctor, the healing status after the medical examination, etc. is displayed. The member sequentially selects an evaluation that he or she thinks appropriate from five-level evaluation by key operation, and sends it to the periodontal disease preliminary examination site 6. The reservation server 65 adds 1 point as a diagnostic point to the diagnostic point field of the database server 67. By responding to the questionnaire, the member can collect the deposit and receive each prize according to the accumulated points of the diagnostic points. By accessing the reservation server 65 via the WWW server 66, the member can know his or her accumulated points.
Detailed information can be obtained by referring to the home page of the WEB server 64 via the W server 66.

The dentist notifies the WEB server 64 of the visit via the WWW server 66 after the examination of the member (patient) who made the appointment for the visit. This allows the member to cancel the deposit.

The reservation server 65 evaluates the dentist and ranks the dentist every predetermined period (for example, 3 months) based on the questionnaire results answered by the members. The ranking can also be reflected in the selection of the recommended dentist in step 214. Therefore, the member can receive the recommendation of a highly ranked dentist even if he or she is a little away from home. In this case, in addition to the member ID and password from the mobile phone 1 to the periodontal disease preliminary examination site 6, it is sufficient to select and send a message that the recommended dentist is desired based on the ranking. In step 214, the analysis server 68 refers to the address of the member and selects the top three dentists with a high ranking from the adjacent ward, city, town, and village. The periodontal disease preliminary examination site 6 may charge the member for such special information.

On the other hand, if a negative decision is made in step 110 of FIG. 5, another process is carried out in the next step 114 to end the host processing routine. As described above, in addition to the processes related to registration of dentists, processes related to homepages, processes related to questionnaires, etc., this separate process includes support for aftercare for patients by dentists and halitosis check by members, which are described below. Is included.

The dentist maintains the regular oral health of the patient who has visited more than once, and when the periodontal disease is not completely cured, the dentist prompts the patient to visit.
Preliminary examination site 6 for periodontal disease from personal computer 8
Access to. If the WWW server 66 determines that the care is from the dentist, the process is passed to the reservation server 65. The reservation server 65 displays the aftercare screen on the display of the personal computer 8 of the dentist. The dentist describes the patient's name, address, and the fact that a visit is required and sends it to the periodontal disease preliminary examination site 6. Upon receiving this transmission, the reservation server 65 searches the visit reservation history for the member ID of the member, and the database server 6
The mail address of the member is acquired from 7, and the mail is sent to the member's mobile phone 1 via the WWW server 66. Therefore, aftercare can become a business for the dentist.

As described above, in the periodontal disease preliminary examination, the gas produced by the periodontal disease-causing bacteria is detected by measuring and analyzing the exhaled breath, so that it is possible to indirectly check the bad breath. However, halitosis is caused by the decomposition of substrates such as proteins by a degrading enzyme possessed by microorganisms resident in the oral cavity or an enzyme originally contained in saliva to generate an odor. Due to the mixed gas consisting of. In normal humans, around 200 species of indigenous bacteria and microorganisms called flora also exist in the oral cavity, and the number of them reaches billions. Most of these are microaerobes and anaerobes. From such a background, it is difficult to cover all the bad breath with the above-mentioned four kinds of semiconductor gas sensors 23, but it is possible to roughly check the bad breath. Table 1 below summarizes the odors produced in the oral cavity and derived from outside the body.

[0060]

[Table 1]

Semiconductor gas sensors PA2, T50 / 3, P10 / 9, P40 / 1 built into the breath measuring device 2.
Measures all substances other than skatole shown in Table 1.
Can be recognized. In the bad breath check of the present embodiment, if the maximum specific resistance value of any of the above-mentioned four types of semiconductor gas sensors exceeds a predetermined threshold value, it is detected that there is bad breath,
Inform the member's mobile phone 1 of the "type of odor" in Table 1 by email. Such processing can be performed by the analysis server 68. Therefore, the member who wishes to check his or her own bad breath should access the periodontal disease preliminary examination site 6 and select the bad breath check, and grasp the status of his or her own bad breath by another processing in step 114 of the WWW server 66. Is possible. You may charge for such a service.

In addition to the above deposit processing and point processing, the billing management server 63 bills the dentist for the monthly fee and carries out the periodontal disease preliminary examination site 6 every predetermined period (for example, one month). The members (patients) introduced by will be charged for those who have visited the hospital and for aftercare. In addition, the database server 67 updates the age from the birth date of each member every day.

As described above, in the present embodiment, the breath data of the user (member) can be measured by the breath measuring device 2 connectable to the mobile phone 1, and the user can measure his / her own breath data at home or work. Since the periodontal disease preliminary examination data can be transmitted to the periodontal disease preliminary examination site 6 by measuring, the periodontal disease preliminary examination can be easily performed. Further, since the breath measuring device 2 can be connected to the mobile phone 1 of an arbitrary user via the connection cable 9, it can be installed in an arbitrary place such as a convenience store.

The exhalation measuring instrument 2 of this embodiment is 2,
Since 400 pieces of exhalation data are used as 16 pieces of user measurement data, the amount of communication with the periodontal disease preliminary examination site 6 by the mobile phone 1 can be significantly reduced. Moreover, since it determines (determines) whether or not the expiration data is appropriate before communication,
Useless communication can be eliminated.

Further, as shown in FIG. 6, the analysis server 68 of the present embodiment reads the periodontal disease preliminary examination data stored in the database server 67 (step 20).
6) is input to the input layer of the neural network composed of the input layer, the intermediate layer and the output layer, and the output layer is operated to output a correlation value representing the correlation with the degree of progression of periodontal disease (step 208). ), It is determined to which of the periodontal disease progress classifications, which are divided into a plurality of predetermined periodontal disease progressions, according to the calculated correlation value (step 21).
0), the WWW server 66 is made to send the judgment result to the user's mobile phone 1 by mail (step 22).
2) Therefore, the user (member) can receive the preliminary examination result of periodontal disease by e-mail in a short time after the self-expiration measurement work. In addition, the email received by the user (member) has 3
Since the preliminary examination results divided into categories are shown, it is possible to grasp (recognize) the degree of progression of the periodontal disease of oneself without medical knowledge. Further, when the member is suspicious of or has a high possibility of periodontal disease, the member can receive the recommendation of a plurality of dentists, and thus, an opportunity to cure the periodontal disease can be obtained. Moreover, it is possible to receive a recommendation from a dentist close to home or a dentist having a high rank (reliable) based on the evaluation of a questionnaire.

In this embodiment, the member is the mobile phone 1
Thus, by accessing the periodontal disease preliminary examination site 6, it is possible to make a visit appointment to the dentist at his / her own convenience, and it is possible to receive treatment from the dentist easily and quickly. In addition, since the dentist can also provide aftercare to the member, it is possible to give the member who has neglected to treat the periodontal disease having no subjective symptom an opportunity to completely cure or periodically diagnose the periodontal disease. Furthermore, since the periodontal disease preliminary examination site 6 is not charged to the user (member) in principle, the periodontal disease preliminary examination site 6 can be freely accessed. On the other hand, for contract dentists, periodontal disease preliminary examination site 6
The patient is introduced (reservation to visit the hospital), and after-care is given an opportunity to prompt the member to perform treatment through the periodontal disease preliminary examination site 6, so that business is secured. Further, since the result of the periodontal disease preliminary examination of the patient (member) who has the appointment for visiting the hospital can be referred in advance, it is possible to obtain the preliminary knowledge about the patient and enhance the reliability of the patient. .

Further, in the present embodiment, since the service for checking the bad breath of the members who are worried about bad breath is also provided, the member can objectively know whether there is bad breath or what kind of bad breath. Therefore, it is possible to properly deal with bad breath.

In the present embodiment, an example in which the form telephone 1 and the exhalation measuring instrument 2 are connected by the connection cable 9 has been shown on the assumption that the exhalation measuring instrument 2 is arranged in a convenience store or the like. Built-in Bluetooth module for establishing an ad hoc wireless ring with breath meter 2 that outputs user measurement data within a short distance (about 10 m) from telephone 1 (it can be connected only when necessary, not always connected) You may allow it. With such a configuration, the degree of freedom between the mobile phone 1 and the breath measuring device 2 can be increased. Further, the exhalation meter 2 does not have to have the entire control unit 26, but only needs to have an exhalation data generation section and an interface section.
By attaching the (User Identity Module) card to the mobile phone 1, the Java program downloaded from the periodontal disease preliminary examination site 6 is stored in the memory in the UIM card and the CPU of the mobile phone 1 is operated, thereby exhaling. The same operation as the control unit 26 of the measuring instrument 2 can be executed. If such a configuration is adopted, downsizing of the breath measuring device 2 can be achieved.

Further, in the present embodiment, an example in which the sampling rate of the A / D converter is set to 10 Hz has been shown, but it has been confirmed that the user measurement data is not affected even if the sampling rate is reduced to about 1 Hz. . In addition, in the present embodiment, an example in which the expiration measurement time is set to 60 seconds has been shown.
It is also confirmed that the reliability of the periodontal disease correlation value C output from the output layer of the ANN can be sufficiently ensured even if the time is about 10 seconds. Further, in this embodiment, the suction pump P
Although an example of suctioning at a flow rate of 200 ml / sec was shown,
