[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing a schematic configuration of a tooth management system 1 according to an embodiment of the present invention.

[0020] Referring to FIG. 1, a tooth management system 1 according to an embodiment of the present invention may include a tooth diagnosis device 10, a user terminal 20, and a tooth management server 30.

[0021] The dental diagnosis device 10 may be a device that measures the condition of a user's teeth and / or interdental regions. For example, the dental diagnosis device 10 may be a portable device that measures the condition of a user's teeth and / or interdental regions using an optical sensor. However, the present invention is not limited thereto and may be applied to all types of dental diagnosis devices 10. For example, the dental diagnosis device 10 may include an acidity (pH) measurement type dental diagnosis device, a camera-based dental diagnosis device, and a dental diagnosis device 10 that is linked to an X-ray.

[0022] FIG. 2 is a block diagram showing a schematic configuration of a dental diagnosis device 10 according to an embodiment of the present invention. Referring to FIG. 2, the dental diagnosis device 10 may include a condition information measurement unit 110, a user interface unit (device UI) 120, a device communication unit 130, and a device processor 140.

[0023] The status information measuring unit 110 may include an optical sensor that measures the status of the teeth and / or interdental areas of the user based on transmission and reception of light (e.g., laser), or may correspond to a probe including a pH sensor that measures the acidity (pH) of the teeth and / or interdental areas of the user.

[0024] Hereinafter, for convenience of explanation, "condition information of teeth and / or interdental areas" will be referred to as "tooth-related condition information."

[0025] The device UI (User Interface) 120 can receive an input signal from a user and display various information related to the status information measurement unit 110 .

[0026] The device communication unit 130 may be a communication module that communicates with an external electronic device. In particular, the device communication unit 130 may transmit tooth-related status information to the user terminal 20. To this end, the device communication unit 130 may include a short-range communication module. In particular, the device communication unit 130 may include a Bluetooth module.

[0027] The device processor 140 may include one or more of a central processing unit including an internal memory, an application processor, or a communication processor. The device processor 140 may perform calculations and data processing related to control and / or communication with at least one other component of the dental diagnosis device 10. In particular, the device processor 140 may generate condition information of the teeth and / or interdental regions measured by the condition information measurement unit 110.

[0028] The tooth-related condition information may correspond to a condition number (or a caries progression value). For example, the condition number may have any one of a range of 0 to 99 points. The higher the condition number, the more severe the caries in the tooth and / or interdental area may be, and the lower the condition number, the healthier the tooth and / or interdental area may be.

[0029] According to an embodiment, the tooth-related condition information may be expressed in a plurality of stages, which may include a first stage, a second stage, and a third stage.

[0030] The first stage may be a cavity-free stage. The cavity-free stage may be a stage where the tooth is hardly damaged. For example, the range of the condition value corresponding to the first stage may be 0 to 19 points.

[0031] The second stage may be a caries warning stage. The caries warning stage may be a stage where the tooth enamel is damaged. For example, the range of condition values ​​corresponding to the second stage may be 20 to 39 points.

[0032] The third stage may be a caries risk stage. The caries risk stage may be a stage where the enamel and dentin of the teeth are damaged. For example, the range of condition values ​​corresponding to the third stage may be 40 to 99 points.

[0033] Referring to the above, the dental diagnosis device 10 can calculate tooth-related condition information (condition numerical value) based on information measured by the optical sensor or pH sensor, and transmit the calculated tooth-related condition information of the user to the user terminal 20. However, the present invention is not limited thereto. According to another embodiment, the dental diagnosis device 10 can transmit information measured by the optical sensor or pH sensor to the user terminal 20, and the user terminal 20 can calculate tooth-related condition information (condition numerical value) based on the information measured by the optical sensor or pH sensor.

[0034] 1, the user terminal 20 may be a terminal owned by a user. For example, the user terminal 20 may be a smart device such as a smartphone, a smart pad, a smart watch, or a smart TV.

[0035] If the user is an adult, the user terminal 20 may be a terminal owned by the user. If the user is a child, the user terminal 20 may be a terminal owned by the user's guardian. The user terminal 20 can receive the tooth-related condition information of the user measured by the dental diagnosis device 10 and can generate oral cavity result condition information of the user based on the received tooth-related condition information. The oral cavity result condition information can be visually output to the user.

[0036] FIG. 3 is a block diagram showing a schematic configuration of a user terminal 20 according to an embodiment of the present invention. Referring to FIG. 3, the user terminal 20 may include a terminal communication unit 210 , a terminal UI 220 , a display unit 230 , a terminal memory 240 , and a terminal processor 250 .

[0037] The terminal communication unit 210 may be a communication module that communicates with the tooth diagnosis device 10 and the tooth management server 30. To this end, the terminal communication unit 210 may include a first terminal communication module and a second terminal communication module.

[0038] The first terminal communication module can communicate with the dental diagnostic device 10. As an example, the first terminal communication module can be a short-range communication module, in particular a Bluetooth module.

[0039] The second terminal communication module can communicate with the tooth management server 30. For example, the second terminal communication module can be a short-range communication module (for example, a Wi-Fi (registered trademark) module) and / or a long-range communication module.

[0040] The terminal UI 220 can receive input signals from a user, which can include text signals, voice signals, and touch event signals. The display unit 230 may be a device capable of displaying an image or an image frame to a user. The display unit 230 may output an execution screen of an application executed by the terminal processor 250 (described later), and may particularly visually display various tooth images.

[0041] Meanwhile, the terminal UI 220 and the display unit 230 may be implemented as a single device. That is, the display unit 230 may be a touch display to which a user's touch signal is input. In this case, the terminal UI 220 may be omitted from the user terminal 20.

[0042] The terminal memory 240 may be a volatile and / or non-volatile memory and may store commands or data related to at least one other component of the user terminal 20. In particular, the terminal memory 240 may store commands or data related to an application (computer program or recording medium) executed in the user terminal 20.

[0043] The device memory 240 may also store information related to a user (i.e., user information), information related to tooth management, etc. Here, the user information may be input and collected by the user, and information related to tooth management may be collected from the outside via the device communication unit 210.

[0044] The terminal processor 250 may include one or more of a central processing unit, an application processor, or a communication processor. The terminal processor 250 may perform calculations and data processing related to control and / or communication with at least one other component of the user terminal 20. In particular, the terminal processor 250 may execute commands of an application.

[0045] 1 again, the tooth management server 30 may receive and store various information stored in the user terminal 20. To this end, the tooth management server 30 may include a communication unit, a memory, a processor, etc.

[0046] Hereinafter, the tooth management method will be described in detail with reference to FIGS. FIG. 4 is a flowchart showing an overall procedure of a tooth management method according to an embodiment of the present invention.

[0047] At this time, all steps of the tooth management method shown in Fig. 4 may be performed by the user terminal 20. Meanwhile, some steps of the tooth management method shown in Fig. 4 may be performed by the tooth management server 30. At this time, some steps may be steps S10 to S40, which will be described later, and a step of generating an information or notification message to the user in step S50. Hereinafter, for convenience of explanation, it is assumed that the tooth management method is performed by the user terminal 20.

[0048] It is also assumed that the user terminal 20 is a smartphone equipped with a touch display unit 230. It is also assumed that the tooth management method is performed by a tooth management application executed on the user terminal 20, and that the user terminal 20 has established a communication connection (e.g., Bluetooth pairing) with the tooth diagnosis device 10. It is also assumed that the tooth condition information is a tooth condition numerical value.

[0049] The process performed at each stage will be described in detail below. In step S10, the user terminal 20 may collect first tooth condition values ​​of the user's teeth measured by the tooth diagnosis device 10 during a first measurement period. The first measurement period may be defined as a measurement period during which the user's tooth condition values ​​are measured for the first time. The first measurement period may be a period corresponding to a specific day.

[0050] In step S20, the user may input the user's dental self-management information during the non-measurement period into the user terminal 20. Here, the non-measurement period may be a period that comes after the first measurement period and may be a period consisting of multiple days. For example, the non-measurement period may be 15 days, but the present invention is not limited thereto.

[0051] During the non-measurement period, tooth condition values ​​may not be received by the dental diagnosis device 10. That is, the non-measurement period may be a time interval between a first measurement period and a second measurement period described below.

[0052] The self-care tooth information may be input via the touch display unit 230 of the user terminal 20. That is, during the non-measurement period, the user may input the self-care tooth information into the user terminal 20. According to an embodiment, the self-care tooth information may include at least one of tooth brushing information performed by the user during the non-measurement period, toothbrush type information when brushing teeth, and dental floss use information.

[0053] Meanwhile, the dental self-care information may be input to the user terminal 20 on a daily basis, for example. If the user does not take care of their teeth on a specific day, the user may not input the dental self-care information to the user terminal 20. That is, the dental self-care information may be input to the user terminal 20 only on the specific day on which the user takes care of their teeth.

[0054] To have the user input dental self-care information, the user terminal 20 can output (i.e., display) prompting messages to the user during non-measurement periods to guide the user in dental self-care. Prompt messages can also be output to the user terminal 20 on a daily basis. The user may perform dental self-care after checking the prompt message. The dental self-care information can correspond to a response to the prompt message. For example, the prompt message can be, "Did you brush your teeth today?", "Did you use dental floss between your molars that are in the caries warning stage?", etc.

[0055] In step S30, the user terminal 20 may collect second dental condition values ​​of the user's teeth measured by the dental diagnosis device 10 during a second measurement period. The second measurement period may be a period that comes after the non-measurement period. That is, the second measurement period may be a measurement period in which the dental condition values ​​of the user are collected by the dental diagnosis device 10 after the first measurement period. The second measurement period may be a period corresponding to a specific date.

[0056] Meanwhile, the number of teeth for which the second tooth condition value is measured in the second measurement period may be the same as or different from the number of teeth for which the first tooth condition value is measured in the first measurement period.

[0057] In step S40, the user terminal 20 may calculate the user's dental deterioration numerical value information for the second measurement period based on the first and second dental condition numerical values ​​of the user's teeth. This may be performed by the terminal processor 250.

[0058] Here, the dental deterioration numerical value information is defined as information indicating how much the dental condition of the user in the second measurement period has worsened compared to the dental condition of the user in the first measurement period. The dental deterioration numerical value information may correspond to a dental deterioration numerical value. For convenience of explanation, the present embodiment will be described below assuming that the "dental deterioration numerical value information" is a "dental deterioration numerical value."

[0059] Generally, dental conditions do not improve naturally without receiving treatment at a hospital. Therefore, the dental deterioration value cannot have a negative value and can have a value greater than or equal to 0. In addition, the dental deterioration value can become higher as the dental condition worsens over time.

[0060] An embodiment of step S40 will now be described in more detail with reference to Figures 5 to 7. Figure 5 is a flowchart showing an embodiment of step S40.

[0061] 5, in step S40, the user terminal 20 may select at least one first tooth from the user's teeth based on the second tooth condition numerical value of each of the user's teeth, and calculate tooth deterioration numerical value information by comparing the second tooth condition numerical value of each of the at least one first tooth with the first tooth condition numerical value of each of the at least one first tooth. This will be described in detail as follows.

[0062] In step S411, the user terminal 20 may select at least one first tooth from the user's teeth based on the second tooth condition numerical value of each of the user's teeth. According to an embodiment, the user terminal 20 may select at least one first tooth from the user's teeth that has a second tooth condition numerical value equal to or greater than a preset tooth condition critical numerical value.

[0063] In this case, the critical tooth condition value may correspond to the minimum tooth condition value that will damage tooth enamel. As an example, as described above, the tooth condition value may be included in any one of the caries-safe stage (stage 1, 0-24 points), the caries warning stage (stage 2, 25-35 points), and the caries-risk stage (stage 3, 36-99 points), and the critical tooth condition value may be 25 points, which is the minimum value of the caries warning stage (i.e., the minimum tooth condition value that will damage tooth enamel). As another example, the critical tooth condition value may be 36 points, which is the minimum value of the caries-risk stage (i.e., the minimum tooth condition value that will damage tooth dentin).

[0064] In step S412, the user terminal 20 may calculate a sum of the second tooth condition numerical values ​​for each of the at least one first tooth. In step S413, the user terminal 20 may calculate a sum of the first tooth condition numerical values ​​for each of the at least one first tooth. In step S414, the user terminal 20 may calculate tooth deterioration numerical information for the second measurement period based on the difference between the sum of the second tooth condition numerical values ​​for the at least one first tooth and the sum of the first tooth condition numerical values.

[0065] As an example, the dental deterioration numerical information may be a simple difference value (i.e., a difference value not reflecting a weighted value) between the sum of the second dental condition numerical values ​​and the sum of the first dental condition numerical values, or may be a difference value reflecting a weighted value between the sum of the second dental condition numerical values ​​and the sum of the first dental condition numerical values.

[0066] Hereinafter, an embodiment of step S40 described in Fig. 5 will be described in detail with reference to Fig. 7. Referring to Fig. 7, the first tooth condition numerical values ​​of six teeth, namely, teeth A, B, C, D, E, and G, are measured in a first measurement period. Meanwhile, the tooth condition of tooth F is not measured in the first measurement period, and therefore tooth F may have a first tooth condition numerical value of the default value (=0).

[0067] Then, during the second measurement period, the second tooth condition values ​​of seven teeth, namely, teeth A, B, C, D, E, F, and G, were measured. In the case of tooth G, the second tooth condition value was smaller than the first tooth condition value. Therefore, it can be inferred that tooth G was treated at a hospital.

[0068] Based on the above, the calculation of the dental deterioration numerical information by the user terminal 20 will be described below. It is assumed that the dental condition critical value is 25 points, and the dental deterioration numerical information is the simple difference between the sum of the second dental condition numerical values ​​and the sum of the first dental condition numerical values.

[0069] First, the user terminal 20 may select four teeth (teeth A, B, D, and E) among the seven teeth whose second tooth condition numerical values ​​are equal to or greater than the tooth condition critical numerical value (=25) as first teeth. Next, the user terminal 20 may calculate the sum (=158) of the second tooth condition numerical values ​​of each of the four first teeth (teeth A, B, D, and E).

[0070] Next, the user terminal 20 can calculate the sum (=120) of the first tooth condition values ​​of each of the four first teeth (tooth A, B, D, and E). Finally, the user terminal 20 can calculate the difference (=38) between the sum (=158) of the second tooth condition values ​​and the sum (=120) of the first tooth condition values ​​as the tooth deterioration value.

[0071] In other words, according to one embodiment of step (S40), if a tooth in a caries-free stage is used to calculate the tooth deterioration value, the tooth deterioration value may not accurately reflect the actual degree of deterioration of the user's teeth. Therefore, the user terminal 20 may use only the first tooth, which is a tooth belonging to the caries warning stage and the caries risk stage, to calculate the tooth deterioration value, and may not use teeth belonging to the caries-free stage to calculate the tooth deterioration value.

[0072] As described above, the dental deterioration value is defined so that it cannot have a negative value. However, if tooth F that has received treatment at a hospital is used to calculate the dental deterioration value, the dental deterioration value will have a decreased value. Therefore, to prevent errors in calculating the dental deterioration value and accurately calculate the dental deterioration value, teeth that have received treatment at a hospital during the non-measurement period can be excluded from calculating the dental deterioration value.

[0073] Figure 6 is a flowchart showing another embodiment of the above-mentioned step (S40). Each step of Figure 6 will be described below with reference to Figure 7. In step (S421), the user terminal 20 can select at least one first tooth from among the user's teeth that has not received treatment during the non-measurement period.

[0074] As described above, teeth that have received treatment at a hospital during the non-measurement period may not be used in calculating the tooth deterioration value. In this case, the user may directly input information about the treated teeth into the touch display 230, or the information may be confirmed by comparing the second tooth condition value with the first tooth condition value for each tooth.

[0075] 7, the user terminal 20 may select six teeth (tooth A, B, C, D, E, and F) that have not received treatment at a hospital as first teeth out of seven teeth. In step S422, the user terminal 20 may set a weight value for each first tooth based on the second tooth condition value of each of at least one first tooth. In this case, the weight values ​​for each first tooth may be the same or different.

[0076] According to the embodiment, if the second tooth condition numerical value of the first tooth is less than a predetermined first tooth condition critical numerical value, the weighting value of the first tooth may be the first weighting value, and if the second tooth condition numerical value of the first tooth is equal to or greater than the first tooth condition critical numerical value, the weighting value of the first tooth may be the second weighting value.

[0077] In this case, the second weighting value may be set to be greater than the first weighting value. In particular, the first weighting value may have a very small value, for example, a value of 0. In addition, the first tooth condition critical value may be the minimum value of the caries warning stage (i.e., the minimum tooth condition value that damages tooth enamel).

[0078] As an example, referring to FIG. 7, if the first tooth condition critical value is set to 25 points, the weighting values ​​of teeth C and F may have a relatively small first weighting value, and the weighting values ​​of teeth A, B, D, and E may have a relatively large second weighting value.

[0079] According to another embodiment, if the second tooth condition numerical value of the first tooth is less than the first tooth condition critical numerical value, the weight of the first tooth may be the first weight. If the second tooth condition numerical value of the first tooth is equal to or greater than the first tooth condition critical numerical value but less than a predetermined second tooth condition critical numerical value, the weight of the first tooth may be the second weight. If the second tooth condition numerical value of the first tooth is equal to or greater than the second tooth condition critical numerical value, the weight of the first tooth may be the third weight.

[0080] In this case, the second weighting value may be set to be greater than the first weighting value, and the third weighting value may be set to be greater than the second weighting value. In particular, the first weighting value may have a very small value, for example, 0. In addition, the second tooth condition critical value may be the minimum value of the caries risk stage (i.e., the minimum tooth condition value that damages the dentin of the tooth).

[0081] For example, referring to FIG. 7, if the first tooth condition critical value is set to 25 points and the second tooth condition critical value is set to 36 points, the weighted values ​​wC and wF of teeth C and F may have the first weighted value, the weighted values ​​wA and wE of teeth A and E may have the second weighted value, and the weighted values ​​wB and wD of teeth B and D may have the third weighted value.

[0082] In step S423, the user terminal 20 may calculate the difference between the second tooth condition value and the first tooth condition value for each first tooth. For example, referring to FIG. 7, the difference values ​​for six first teeth may be 2, 16, 1, 9, 11, and 7, respectively.

[0083] In step S424, the user terminal 20 may calculate a weighted-reflected difference value for the first tooth based on the difference value for the first tooth and the weighted value for the first tooth. According to an embodiment, the user terminal 20 may calculate the weighted-reflected difference value for the first tooth by multiplying the difference value for the first tooth by the weighted value for the first tooth.

[0084] For example, referring to FIG. 7, the weighted values-reflected difference values ​​of the six first teeth may be wA×2, wB×16, wC×1, wD×9, wE×11, and wF×7, respectively.

[0085] In step S425, the user terminal 20 may calculate dental deterioration numerical information based on the weighted value-reflected difference numerical value for each first tooth. According to an embodiment, the user terminal 20 may calculate dental deterioration numerical information by summing the weighted value-reflected difference numerical value for each first tooth.

[0086] For example, referring to FIG. 7, the tooth deterioration numerical information may be (wA×2)+(wB×16)+(wC×1)+(wD×9)+(wE×11)+(wF×7).

[0087] In other words, according to another embodiment of step (S40), teeth that have received treatment at a hospital can be excluded from the calculation of the dental deterioration value. Also, when calculating the dental deterioration value, the weighting value of teeth in the caries-safe stage can be set lower than the weighting values ​​of teeth in the caries-warning stage and the caries-risk stage, so that the dental deterioration value can accurately reflect the actual degree of dental deterioration of the user.

[0088] 4 again, in step S50, the user terminal 20 may provide the user with various information related to the dental deterioration numerical information and / or a dental care notification message guiding the user's dental care. The related information or dental care notification message may be displayed or output on the touch display 230.

[0089] According to the embodiment, in step S50, the user terminal 20 may display the dental deterioration numerical information on the touch display 230. Therefore, the user can easily check whether or not his / her teeth are deteriorated.

[0090] According to the embodiment, in step S20, the dental self-care information may be input at least once during the non-measurement period. In this case, in step S50, the user terminal 20 may calculate the user's dental self-care performance rate during the non-measurement period based on the dental self-care information input at least once. In step S50, the user terminal 20 may combine the user's dental self-care performance rate and dental deterioration numerical information to generate a dental care notification message.

[0091] As an example, if the dental self-care performance rate is greater than a first critical rate corresponding to a high level and the dental deterioration value is greater than a first critical value corresponding to a high level, the user terminal 20 can generate a dental care notification message including correct dental self-care methods and / or genetic predisposition information related to the occurrence of dental caries.

[0092] That is, if the dental self-care performance rate and dental deterioration value are both high, it can be inferred that the user's dental condition has deteriorated significantly despite having taken relatively good care of their teeth during the non-measurement period. The cause of this situation may be that the user is taking incorrect dental care or that the user's teeth are genetically weak. Therefore, the user terminal 20 can inform the user of the correct dental self-care method or inform the user that the user's teeth are genetically weak.

[0093] As another example, if the dental self-care performance rate is lower than a second critical rate corresponding to a low level and the dental deterioration value is higher than a first critical value corresponding to a high level, the user terminal 20 can generate a dental care notification message including information encouraging the user to take care of their teeth themselves.

[0094] That is, if the dental self-care performance rate is low and the dental deterioration value is high, it can be inferred that the user did not take care of their teeth during the non-measurement period despite the fact that their dental condition had deteriorated considerably. Therefore, the user terminal 20 can inform the user that "You are not taking care of your teeth sufficiently. Please take better care of your teeth."

[0095] As another example, if the dental self-care performance rate is greater than a first critical rate corresponding to a high level and the dental deterioration value is less than a second critical value corresponding to a low level, the user terminal 20 can generate a dental care notification message including information that the user has diligently performed dental self-care.

[0096] That is, if the self-care dental practice rate is high and the dental deterioration value is low, it can be inferred that the user has managed their teeth relatively well during the non-measurement period and the dental deterioration value is low. Therefore, the user terminal 20 can inform the user that "You have performed self-care dental practice well and your dental condition has been maintained."

[0097] Meanwhile, a user may belong to the same target management group as at least one other user. For example, the target management group may be a nursery school, kindergarten, nursing home, etc.

[0098] According to the embodiment, in step S50, the user terminal 20 may generate first comparison information by comparing the dental deterioration values ​​of each user belonging to the target management group with the dental deterioration values ​​of the user, and provide the first comparison information to the user, thereby enhancing the user's competitive spirit in dental management.

[0099] Here, the first comparison information may correspond to percentile information of the user's dental deterioration value based on the dental deterioration value of each user belonging to the target management group. For example, the user terminal 20 may provide the user with information that the user's dental deterioration value is in the top 30% of the dental deterioration values ​​of each user belonging to the target management group. However, the present invention is not limited to this, and various information such as ranking information may be provided to the user. In addition, the dental deterioration value of each user belonging to the target management group may be received from the dental management server 30.

[0100] According to another embodiment, in step S50, the user terminal 20 may calculate second comparison information by comparing the dental deterioration numerical information of the target management group with the dental deterioration numerical information of at least one other management group, and provide the second comparison information to the user. This allows the dental deterioration numerical information to be compared by management group, further enhancing the user's competitive spirit in dental management.

[0101] Here, the dental deterioration numerical information of the target management group and at least one other management group may be calculated based on the dental deterioration numerical information of the users belonging to the corresponding management group. For example, the dental deterioration numerical information of the users belonging to the corresponding management group may be an average value of the dental deterioration numerical values ​​of the users. In addition, the dental deterioration numerical values ​​of the other management groups may be received from the dental management server 30.

[0102] Meanwhile, steps S20 to S50 may be repeatedly performed, i.e., steps S20 to S50 may be performed periodically, in which case the tooth condition value of the previous period may be the tooth condition value of the current period.

[0103] Furthermore, embodiments of the present invention may be embodied in the form of program instructions that can be executed by various computer means and stored on a computer-readable medium.
