[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 region. As an example, the dental diagnosis device 10 may be a portable device that measures the condition of a user's teeth and / or interdental region using an optical sensor. However, the present invention is not limited thereto and may be applied to all types of dental diagnosis devices 10. As an example, the dental diagnosis device 10 includes 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 tooth diagnosis device 10 according to an embodiment of the present invention. Referring to FIG. 2, the tooth diagnosis device 10 may include a state information measuring 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 area of ​​the user based on transmission and reception of light (for example, a laser), or may correspond to a probe including a pH sensor that measures the acidity (pH) of the teeth and / or interdental area 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] A device UI (User Interface) 120 can receive an input signal from a user and can display various information related to the status information measuring 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 areas measured by the condition information measurement unit 110.

[0028] The tooth-related condition information may correspond to a condition value (or a caries progression value). For example, the condition value may have any one of a number ranging from 0 to 99. The higher the condition value, the more severe the caries in the tooth and / or interdental area may be, and the lower the condition value, 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 stage where the tooth is free of caries. The stage where the tooth is free of caries 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 enamel of the tooth is damaged. For example, the range of the condition value 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 tooth are damaged. For example, the range of the condition value corresponding to the third stage may be 40 to 99 points.

[0033] Referring to the above, the tooth 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 tooth 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 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 tooth 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 apparatus 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 is capable of communicating with the dental diagnostic apparatus 10. As an example, the first terminal communication module may 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. The input signals 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 in the terminal processor 250 (to be described later), and may visually display various tooth images.

[0041] Meanwhile, the terminal UI 220 and the display unit 230 may be implemented as one device. That is, the display unit 230 may be a touch display to which a user's touch signal is input, in which 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] In addition, the device memory 240 may 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 the 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 applications.

[0045] 1 again, the tooth management server 30 may receive and then 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, and the like.

[0046] Hereinafter, the tooth management method will be described in detail with reference to FIGS. FIG. 4 is a diagram showing an overall flowchart 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 in the user terminal 20. Meanwhile, some steps of the tooth management method shown in Fig. 4 may be performed in the tooth management server 30. At this time, some steps may be steps S10 to S40 described below and a step of generating an information or notification message to a user in step S50. Hereinafter, for convenience of explanation, it is assumed that the tooth management method is performed in 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 completed 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 step 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 in which the dental condition values ​​of the user are measured for the first time, and may be a period corresponding to a specific day.

[0050] In step S20, the user terminal 20 can receive user's self-management information during a non-measurement period. Here, the non-measurement period may be a period that comes after the first measurement period and may be a period consisting of a number of days. As an example, the non-measurement period may be "15 days", but the present invention is not limited thereto.

[0051] During the non-measurement period, no tooth condition values ​​may be received by the dental diagnostic device 10. That is, the non-measurement period may be a time interval between a first measurement period and a second measurement period, which will be described later.

[0052] The tooth self-management information may be inputted through the touch display unit 230 of the user terminal 20. That is, during the non-measurement period, the user may input the tooth management information that he / she has performed himself / herself into the user terminal 20. According to an embodiment, the tooth self-care information may include at least one of information on tooth brushing performed by the user during a non-measurement period, information on the type of toothbrush used when brushing teeth, and information on dental floss use.

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

[0054] In order to have the user input the dental self-care information, the user terminal 20 can output (i.e., display) a prompting message to the user during the non-measurement period to prompt the user to perform dental self-care. The prompting message can also be output to the user terminal 20 on a daily basis. The user may perform dental self-care after checking the prompting message. The dental self-care information can correspond to a response to the prompting message. As an example, the prompting 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 values ​​are measured in the second measurement period and the number of teeth for which the first tooth condition values ​​are measured in the first measurement period may be the same or different.

[0057] In step S40, the user terminal 20 may calculate the user's dental deterioration numerical value information in the second measurement period based on the first dental condition numerical value and the second dental condition numerical value 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 deteriorated 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. Hereinafter, for convenience of explanation, this embodiment will be described assuming that the "dental deterioration numerical value information" is a "dental deterioration numerical value".

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

[0060] Hereinafter, an embodiment of step S40 will be described in more detail with reference to FIGS. FIG. 5 is a flowchart showing one embodiment of the above-mentioned step (S40).

[0061] 5, in step S40, the user terminal 20 may select at least one first tooth among 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 among the user's teeth based on the second tooth condition numerical values ​​of each of the user's teeth. According to the embodiment, the user terminal 20 may select at least one first tooth having a second tooth condition value equal to or greater than a preset tooth condition critical value from among the user's teeth.

[0063] In this case, the tooth condition critical value may correspond to the minimum tooth condition value that damages tooth enamel. For example, as described above, the dental condition value may be included in any one of the caries-safe stage (first stage, 0-24 points), the caries-caution stage (second stage, 25-35 points), and the caries-risk stage (third stage, 36-99 points), and the dental condition critical value may be 25 points, which is the minimum value of the caries-caution stage (i.e., the minimum dental condition value that damages the enamel of the tooth). As another example, the dental condition critical value may be 36 points, which is the minimum value of the caries-risk stage (i.e., the minimum dental condition value that damages the dentin of the tooth).

[0064] In step S412, the user terminal 20 may calculate a sum of the second tooth condition values ​​of each of the at least one first tooth. In step S413, the user terminal 20 may calculate a sum of the first tooth condition values ​​of at least one first tooth. In step (S414), the user terminal 20 can calculate tooth deterioration numerical information during the second measurement period based on the difference between the sum of the second tooth condition numerical values ​​for 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 between the sum of the second dental condition numerical values ​​and the sum of the first dental condition numerical values ​​(i.e., a difference value not reflecting a weighted value), 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, with reference to FIG. 7, an embodiment of step S40 described in FIG. 5 will be described in detail. 7, in a first measurement period, first tooth condition numerical values ​​are measured for six teeth, namely, teeth A, B, C, D, E, and G. 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 that is a default value (=0).

[0067] Then, in the second measurement period, the second tooth condition values ​​of the 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 content of calculating the dental deterioration numerical value information by the user terminal 20 will be described. In this case, it is assumed that the dental condition critical value is 25 points, and the dental deterioration numerical value information is the simple difference value 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 can select, as the first teeth, four teeth (teeth A, B, D, and E) whose second tooth condition values ​​are equal to or greater than the tooth condition critical value (=25) among the seven teeth. Next, the user terminal 20 can 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 numerical values ​​of each of the four first teeth (tooth A, B, D, and E). Finally, the user terminal 20 may calculate the difference (=38) between the sum of the second tooth condition values ​​(=158) and the sum of the first tooth condition values ​​(=120) as the tooth deterioration value.

[0071] In short, according to one embodiment of step (S40), when 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 the tooth belonging to the caries-free stage to calculate the tooth deterioration value.

[0072] Also, as described above, the dental deterioration value is defined not to have a negative value. However, when tooth F treated at a hospital is used to calculate the dental deterioration value, the dental deterioration value has a decreased value. Therefore, in order to prevent errors in the calculation of the dental deterioration value and to calculate the dental deterioration value accurately, teeth treated at a hospital during the non-measurement period can be excluded from the calculation of the dental deterioration value.

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

[0074] As described above, teeth that have been treated 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 on the treated teeth into the touch display 230, or the information may be confirmed by comparing the second tooth condition value and the first tooth condition value of each tooth.

[0075] Referring to FIG. 7, the user terminal 20 can select six teeth (teeth A, B, C, D, E, and F) that have not been treated at a hospital among the seven teeth as first teeth. In step S422, the user terminal 20 may set a weight value for each of the first teeth based on the second tooth condition value of each of at least one first tooth. In this case, the weight values ​​for each of the first teeth 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 preset 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. Also, the first tooth condition critical value may be a minimum value of the caries warning stage (i.e., a minimum tooth condition value that may damage tooth enamel).

[0078] As an example, referring to FIG. 7, when 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 weighting value of the first tooth may be the first weighting value. Also, 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 the preset second tooth condition critical numerical value, the weighting value of the first tooth may be the second weighting value. And, 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 weighting value of the first tooth may be the third weighting value.

[0080] At this time, 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, a value of 0. Also, 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] As an 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 a first weighted value, the weighted values ​​wA and wE of teeth A and E may have a second weighted value, and the weighted values ​​wB and wD of teeth B and D may have a third weighted value.

[0082] In step S423, the user terminal 20 may calculate a difference value between the second tooth condition value and the first tooth condition value for each first tooth. As an example, referring to FIG. 7, the difference values ​​for the 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 value-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 the embodiment, the user terminal 20 may multiply the difference value for each first tooth by the weighting value for each first tooth to calculate the weighting value-reflected difference value for each first tooth.

[0084] As an example, referring to FIG. 7, the weights-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 value information based on the weighted value-reflected difference numerical value for each first tooth. According to the embodiment, the user terminal 20 may calculate the dental deterioration numerical value information by summing up the weighted value-reflected difference numerical value for each first tooth.

[0086] As an 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 been treated 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-free stage is set lower than the weighting values ​​of teeth in the caries-caution 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 the 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 value information on the touch display 230. Therefore, the user may easily check whether or not his / her teeth are deteriorated.

[0090] Also, 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. And, in step S50, the user terminal 20 may generate a dental care notification message by combining the user's dental self-care performance rate and dental deterioration numerical information.

[0091] As an example, if the dental self-care implementation rate is greater than a first critical rate corresponding to a high level and the dental deterioration numerical 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 a correct dental self-care method and / or genetic predisposition information for the occurrence of dental caries.

[0092] That is, if the self-care of teeth implementation rate and the dental deterioration value are both high, it can be inferred that the user took relatively good care of their teeth during the non-measurement period, but their dental condition has deteriorated significantly. 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 self-care of teeth 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 self-care of teeth performance rate is low and the dental deterioration value is high, it can be inferred that the user did not care for his / her teeth during the non-measurement period even though the dental condition has deteriorated considerably. Therefore, the user terminal 20 can inform the user of the information "You are not taking sufficient self-care of your teeth. Please take better care of your teeth."

[0095] As another example, if the self-care of teeth 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 self-care of teeth.

[0096] That is, if the self-care of teeth performance rate is high and the dental deterioration value is low, it can be inferred that the user 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 of the information that "You performed self-care of teeth well and maintained the condition of your teeth."

[0097] Meanwhile, a user may belong to the same target management group as at least one other user. As an example, the target management group may be a nursery school, a kindergarten, a nursing hospital, 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 competitive spirit of the users in dental management.

[0099] Here, the first comparison information may correspond to percentile information of the dental deterioration value of the user based on the dental deterioration value of each user belonging to the target management group. As an example, the user terminal 20 may provide the user with information that the dental deterioration value of the user 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 value information of the target management group with the dental deterioration numerical value information of at least one other management group, and provide the second comparison information to the user. This allows the dental deterioration numerical value to be compared by management group, and further enhances the user's competitive spirit in dental management.

[0101] Here, each of 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] Also, 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. The computer-readable medium may include, alone or in combination with, program instructions, data files, data structures, and the like.
