[0001] This application claims the benefit of U.S. Provisional Application No. 61 /808,871 , filed April 5, 2013 and U.S. Provisional Application No. 61 /876,242 filed September 1 1 , 2013, both entitled "Intelligent Tooth Charting Interface." The entirety of both provisional applications is hereby incorporated by reference for all purposes.

Technical Field

[0002] The present disclosure relates generally to systems and methods for tooth charting and, more specifically, to systems and methods for computer-based tooth charting employing an ink-over interface with structured data capture.

Background

[0003] A tooth chart can provide a comprehensive, standardized, graphical view of clinical data {e.g., diagnostic information and/or therapeutic information) related to one or more of a patient's teeth. The clinical data can be represented by annotations {e.g., symbols, texts, and/or colors) that are standardized within the dental community to support a continuity of care within the dental community. Accordingly, dental professionals across the world can understand the clinical data represented in the tooth chart.

[0004] Traditional tooth charts have employed a pen and paper interface that allows dental professionals to make the annotations in locations approximating clinical reality {e.g., the annotation can be made in the proper spatial orientation). However, as dentistry has embraced the digital world {e.g., electronic dental records), traditional pen and paper interfaces have become obsolete. Electronic tooth charts have been developed with keyboard and mouse interfaces to meet the demands of the digital world. However, the keyboard and mouse interfaces allow for imprecise annotations that do not approximate clinical reality. Additionally, dental professionals can find the keyboard and mouse interface cumbersome to document clinical findings and treatment planning, which is very visual in the dental domain. l Summary

[0005] The present disclosure relates generally to systems and methods for tooth charting and, more specifically, to systems and methods for computer-based tooth charting employing an ink-over interface with structured data capture. The ink- over interface allows an input that resembles a traditional pen and paper interface, while providing the computational abilities of the digital world.

[0006] In one aspect, the present disclosure can include a system that can enter clinical data on an electronic tooth chart. The system can include a non-transitory memory storing computer-executable instructions and a processor that executes the computer-executable instructions to at least: receive a graphical data input from an ink-over interface, wherein the graphical data input comprises an annotation associated with a tooth; determine information associated with the annotation based on information stored in a recognition engine; and store the information associated with the annotation as structured data associated with the tooth.

[0007] In another aspect, the present disclosure can include a method for tooth charting. The method can include steps that can be performed by a system that includes a processor. The steps can include: receiving a graphical data input comprising an annotation associated with a tooth from an ink-over interface;

determining information associated with the annotation based on information stored in a recognition engine; and storing the information associated with the annotation as structured data associated with the tooth.

[0008] In a further aspect, the present disclosure can include a tooth charting system. The tooth charting system can include an ink-over interface and a

computing device associated with the ink-over interface. The ink-over interface can be configured to receive a graphical data input comprising an annotation associated with a tooth. The computing device can include a non-transitory memory storing computer-executable instructions; and a processor that executes the computer- executable instructions to at least: detect a gesture associated with the ink-over interface; receive the graphical data input from the ink-over interface based on detection of the gesture; and determine information associated with the graphical data input based on information stored in a recognition engine.

[0028] The present disclosure relates generally to systems and methods for tooth charting and, more specifically, to systems and methods for computer-based tooth charting employing an ink-over interface with structured data capture. The ink- over interface allows an input that resembles a traditional pen and paper interface, while providing a link to the digital world. The systems and methods of the present disclosure can solve problems inherent to electronic tooth charting with keyboard and mouse interfaces that can are not intuitive and provide imprecise annotations. In contrast, the systems and methods of the present disclosure provide an intuitive ink-over interface {e.g., analogous to traditional pen and paper interfaces) for entry of standardized annotations, while also meeting the existing information needs of dental professionals {e.g., by employing optical symbol recognition and a recognition engine to create structured data related to the annotations).

[0029] Although the present disclosure is described with respect to tooth charting, the systems and methods of the present disclosure can be used for other types of dental charting (e.g: periodontal charting) and medical record

documentation. Examples of fields where the systems and methods of the present disclosure can be used include podiatry {e.g., for charting diabetic foot

assessments), dermatology {e.g., for charting skin lesions), and ophthalmology {e.g., for annotation on radiographs).

III. Systems

[0030] One aspect of the present disclosure can include a system for computer- based tooth charting. The system can be employed by a computing device that includes an ink-over interface to facilitate annotating an electronic tooth chart with standardized symbols to document an existing condition, diagnostic information, therapeutic information, and/or planned treatment information. The ink-over interface can allow dental professionals to enter annotations directly over the electronic tooth chart (similarly to the interaction with a pen and paper interface). The annotations can be interpreted and stored as structured data, rather than stored as a static image. For example, the annotations can be interpreted by a computing device according to an optical symbol recognition technique and data related to the annotations can be retrieved from a recognition engine to create structured data related to the annotations that can be stored in connection to the electronic chart. For example, the structured data can be stored in an electronic dental record (EDR) for the patient.

[0031] FIG. 1 illustrates an example of a computing device 8 including an ink- over interface 4 that can be used for computer-based tooth charting. FIG. 1 , as well as associated FIG. 2, are schematically illustrated as block diagrams with the different blocks representing different components. The functions of one or more of the components can be implemented by computer program instructions. The computer program instructions can be provided to a processor of the computing device 8 to produce a machine, such that the instructions, which execute via the processor, can create a mechanism for implementing the functions of the

components specified in the block diagrams.

[0032] The computer program instructions can also be stored in a non-transitory computer-readable memory that can direct the computing device 8 to function in a particular manner, such that the instructions stored in the non-transitory computer- readable memory produce an article of manufacture including instructions, which implement the functions specified in the block diagrams and associated description.

[0033] The computer program instructions can also be loaded onto the computing device 8 to cause a series of operational steps to be performed to produce a computer-implemented process such that the instructions that execute on the computing device 8 provide steps for implementing the functions of the components specified in the block diagrams and the associated description.

[0034] Accordingly, functionalities of the computing device 8 and/or the system 10 can be embodied at least in part in hardware and/or in software (including firmware, resident software, micro-code, etc.). Furthermore, aspects of the computing device 8 and/or the system 10 can take the form of a computer program product on a computer-usable or computer-readable storage medium having computer-usable or computer-readable program code embodied in the medium for use by or in connection with an instruction execution system. A computer-usable or computer-readable medium can be any non-transitory medium that is not a transitory signal and can contain or store the program for use by or in connection with the instruction or execution of a system, apparatus, or device. The computer-usable or computer-readable medium can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus or device. More specific examples (a non-exhaustive list) of the computer-readable medium can include the following: a portable computer diskette; a random access memory; a read-only memory; an erasable programmable read-only memory (or Flash memory) ; and a portable compact disc read-only memory.

[0035] As shown in FIG. 1 , one aspect of the present disclosure can include a computing device 8 that can be used for computer-based tooth charting. The computing device 8 can include at least an ink-over interface 4, a display (or display device) 6, a non-transitory memory, and a processor. For example, the computing device 8 can be a tablet computing device, a smart phone device, a personal media player device, a personal entertainment system device, a laptop computing device.

[0036] The ink-over interface 4 and the display 6 can be coupled so that an annotation made using the ink-over interface {e.g., graphical data input (GDI)) can correspond with a tooth and/or a location on the electronic dental chart (EDC) displayed on the display 6. The ink-over interface 4 and/or the display 6 can be implemented in hardware and/or in software. The non-transitory memory of the computing device 8 can store instructions that are executable by the processor at least to receive the graphical data input (GDI) from the ink-over interface 4 (e.g., in response to being contacted by an input device 2, such as a stylus) and/or to display an electronic tooth chart (EC) on the display 6.

[0037] In some instances, the electronic tooth chart can be displayed by the display 6 with one or more views of a portion of the electronic tooth chart. For example, one view can include a zoomed in view of one or more teeth from the electronic tooth chart. In this case, the graphical data input can be based on a gesture that includes a symbol drawn on the zoomed in view of the one or more teeth at a certain location on the one or more teeth (e.g., the symbol can indicate one or more caries and the location of the symbol can correspond to the location of the one or more caries on the surface of the corresponding tooth).

[0038] FIG. 2 is a schematic block diagram showing a system 10 for computer- based tooth charting that can be employed by the computing device 8 shown in FIG. 1 . The ink-over interface 4 and the display 6 perform functionalities similar to those described with respect to FIG. 1 . The display 6 can display the electronic tooth chart (EC), and the ink-over interface can provide graphical data inputs (GDI) related to at least a portion of the electronic tooth chart (EC) {e.g., related to one or more teeth).

[0039] An example 30 of an electronic tooth chart (EC) and corresponding components that can be displayed by display 6 is illustrated in FIG. 3. The components can include patient information (e.g., name, date of birth, contact information, chronic medical conditions, a photograph, etc.). The components can also include a plurality of selectable tools that can be utilized in connection with the ink-over interface 4. In some instances, the tools can include a pen tool with different selectable colors and an eraser tool. The display can also include a history {e.g., related to previous annotations on the tooth). In some instances, the display can also include one or more x-ray images {e.g., from the electronic dental record (EDR)). The display can also include one or more actions that can be performed on the electronic tooth chart (EC) {e.g., annotate tooth, edit history of tooth, view previous versions of the chart, etc.).

[0040] The electronic tooth chart (EC) can include all 32 permanent human teeth (adult teeth), 20 primary human teeth (baby teeth), or a combination of mixed dentition, numbered according to dental convention. The human teeth can be presented in one or more views in the EC {e.g., illustrating the entire tooth and root, illustrating the top of the tooth, etc.). Each of the teeth in the EC is selectable for annotation. The annotation can occur in either the full tooth chart view or in a zoomed window created in an area of interest mode. For example, the area of interest mode can be activated by a tap gesture on one of the teeth. An additional window can be displayed with a zoomed in version of the tooth (and may include additional surrounding teeth). For example, the zoomed in version can include a 2x zoom area of the selected tooth. A double-tap gesture can allow the zoomed in version to be further zoomed in {e.g., 4x). An annotation can be made on the zoomed in version of the tooth and gestures related to the annotation can be used to identify the annotation. The history related to the tooth can be updated with structured data related to the annotation {e.g., with progress notes showing the progression of the tooth through history). [0041 ] Referring again to FIG. 2, the system 1 0 can include components including at least an ink-over interface receiver 1 2, an annotation analyzer 14, and a structured data unit 1 6. The components can facilitate receiving the graphical data input (GDI) from the ink-over interface 4, interpreting the graphical data input (GDI) into an annotation (e.g., a symbol, a text, and/or a color defined within the dental field), and storing an interpretation of the annotation (AN) in structured data (SD).

[0042] One or more of the components can include instructions that are stored in a non-transitory memory 22 and executed by a processor 24. Each of the components can be in a communicative relationship with one or more of the other components, the processor 24, and/or the non-transitory memory 22 (e.g., via a direct or indirect electrical, electromagnetic, optical, or other type of wired or wireless communication) such that an action from the respective component causes an effect on one or more of the other components and/or on the electronic tooth chart (EC).

[0043] The ink-over interface receiver 1 2 can be configured to receive a graphical data input (GDI) from an ink-over interface 4. In some instances, the graphical data input (GDI) can include an annotation associated with one or more teeth on a dental chart. For example, the annotation can include one or more of: a location on the tooth associated with the annotation, information related to an existing condition, diagnostic information, therapeutic information, and information related to a planned treatment or procedure.

[0044] A state diagram 32 showing the operation of the ink-over interface receiver 1 2 in the receipt of graphical data information (GDI) is illustrated in FIG. 4. At element 34, a digital annotation can be created in response to the system 1 0 entering an annotation state (e.g., by selection of an annotation operation). In some instances, the ink-over interface receiver 1 2 can detect various touch events by polling an operating system associated with the computing device 8. At element 36, the ink-over interface receiver 1 2 can wait for a touch event. Upon receiving a beginning touch event (e.g., at element 38), the ink-over interface receiver 1 2 can add a point associated with the beginning touch event to a new curve (e.g., at element 40). Then, the ink-over interface receiver 1 2 can wait for a new touch event. Upon detection of a new touch event moved from the beginning touch event (e.g., at element 42), the ink-over interface receiver 1 2 can add the new point to the existing curve {e.g., at element 44) and wait for the next touch event. When there are no more touch events {e.g., at element 46) after a period of time {e.g., one second or more), the ink-over interface receiver 12 can end the existing curve {e.g., at element 48). When the ink-over interface receiver 12 ends the existing curve, the resulting annotation can be sent to the annotation analyzer 14 for pattern recognition {e.g., at element 50) and/or further processing.

[0045] FIG. 5 shows example graphical illustrations of various annotations that can be part of the graphical data input (GDI). Illustration 52 shows an extraction annotation on an example tooth. A dental professional can draw two intersecting lines, which are not horizontal or parallel to the orientation of the display. Illustration 54 shows a root canal annotation on an example tooth. A dental professional can draw a single line on a root of the tooth, which system 10 can interpret as a root canal pattern and find corresponding information in the recognition engine 18.

Illustration 56 shows a caries annotation on an example tooth. A dental professional can draw a curve over the tooth. The annotation can be completed when the dental professional taps within the closed curve. If the curve is closed, system 10 can accept the pattern. In some instances, system 10 can test the pattern against the crown of the tooth and reshape the pattern to fit within the crown that is extracted by edge detection and region extraction if a small amount of the curve extends beyond the border of the crown.

[0046] Referring again to FIG. 2, the annotation analyzer 14 can be configured to determine information associated with the annotation (AN) based on information stored in a recognition engine 18. The annotation can be associated with a tooth or a plurality of teeth. For example, the annotation analyzer 14 can employ an optical symbol recognition technique identify the annotation {e.g. the symbol, the text, and/or the color) from the graphical data input (GDI). The annotation identified by the optical symbol recognition can be compared to information stored in the recognition engine 18 {e.g., information associated with the combination of the symbol, the text, and/or the color) to determine the information associated with the annotation (AN). In some instances, the recognition engine 18 can be located within the computing device 8 of FIG. 1 . In other instances, at least a portion of the recognition engine 18 can be located remote from the computing device 8. [0047] FIG. 6 is a state diagram 60 of the identification of the annotation by the annotation analyzer 14. When the annotation is passed to the annotation analyzer 14 by the ink-over interface receiver 12, the annotation analyzer can determine if the annotation matches stored information within the recognition engine 18 {e.g., at element 62). If the match is found {e.g., at element 64), structured data (SD) related to the annotation can be created {e.g., at element 65) by the structured data unit 16 from information associated with the identified annotation {e.g., stored in the recognition engine 18). In some instances {e.g., when the annotation matches a lesser-known pattern), the annotation can be passed to a progress note creator that allows the dental professional to enter the associated structured data (SD) {e.g., by selecting one or more procedures and/or diagnoses associated with the annotation).

[0048] If a match for the annotation is not found in the recognition engine 18 {e.g., at element 66), the annotation can be moved to a pattern failed state. The annotation analyzer 14 can prompt the dental professional to complete the

annotation correctly by starting an annotation assistant {e.g., at element 67). The annotation assistant can prompt the dental professional to clear the current annotation, persist with the image as unstructured data, and/or make

recommendations to guide the dental professional to an alternate means of creating the structured data (SD).

[0049] Referring again to FIG. 2, the structured data unit 16 can be configured to store the information associated with the annotation (AN) as structured data (SD). The structured data (SD) can be associated with the tooth or the plurality of teeth associated with the annotation. In some instances, the structured data (SD) can persist with the associated tooth or plurality of teeth with the electronic tooth chart (EC) {e.g., as a progress note). The structured data can be populated based on information associated with the identified annotation and/or based on a selection of a progress state from a set of potential progress states associated with the annotation. The structured data (SD) can persist between different views associated with the electronic tooth chart and with different access times of the electronic tooth chart (EC) {e.g., providing a dental history for the associated patient that can be accessed at different dental appointments). In some instances, the structured data can be presented across different times starting with the most recent progress note. If the tooth has been extracted, the previous progress notes can be deleted.

[0050] When the structured data is accepted as associated with the tooth, it can persist with the tooth. In some instances, the structured data can be stored in an electronic dental record (EDR). The electronic dental record (EDR) can include additional information that can provide a complete dental history for the patient {e.g., x-rays). In other instances, the structured data can be included in the electronic tooth chart (EC). The electronic tooth chart (EC) can be transmitted to the display 6 and the structured data (SD) can be visually displayed with the rest of the electronic tooth chart (EC).

IV. Methods

[0051] Another aspect of the present disclosure can include a method for tooth charting. An example of a method 70 that can detect annotations entered via an ink- over interface is shown in FIG. 7. Another example of a method 80 for computer- based tooth charting employing an ink-over interface is shown in FIG. 8.

[0052] The methods 70 and 80 of FIGS. 7 and 8, respectively, are illustrated as process flow diagrams with flowchart illustrations. For purposes of simplicity, the methods 70 and 80 are shown and described as being executed serially; however, it is to be understood and appreciated that the present disclosure is not limited by the illustrated order as some steps could occur in different orders and/or concurrently with other steps shown and described herein. Moreover, not all illustrated aspects may be required to implement the methods 70 and 80.

[0053] One or more blocks of the respective flowchart illustrations, and combinations of blocks in the block flowchart illustrations, can be implemented by computer program instructions. The computer program instructions can be stored in memory and provided to a processor of a general purpose computer, special purpose computer, and/or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer and/or other programmable data processing apparatus, create mechanisms for implementing the steps/acts specified in the flowchart blocks and/or the associated description. In other words, the steps/acts can be implemented by a system comprising a processor that can access the computer-executable instructions that are stored in a non-transitory memory.

[0054] The methods 70 and 80 of the present disclosure may be embodied in hardware and/or in software (including firmware, resident software, micro-code, etc.). Furthermore, aspects of the present disclosure may take the form of a computer program product on a computer-usable or computer-readable storage medium having computer-usable or computer-readable program code embodied in the medium for use by or in connection with an instruction execution system. A computer-usable or computer-readable medium may be any non-transitory medium that can contain or store the program for use by or in connection with the instruction or execution of a system, apparatus, or device.

[0055] Referring to FIG. 7, an aspect of the present disclosure can include a method 70 for detecting annotations {e.g., symbols, text, and/or colors) entered via an ink-over interface {e.g., ink-over interface 4). A gesture associated with the ink- over interface can be detected {e.g., by ink-over interface receiver 12) at step 72. The gesture can define a graphical data input (GDI) that is analyzed for the associated annotation. For example, in annotation state, various touch events can be detected {e.g., by ink-over interface receiver 12) by polling an operating system of an associated computing device {e.g., computing device 8). Upon receiving a beginning touch event a point associated with the beginning touch event can be added to a new curve. Upon detection of a new touch event moved from the beginning touch event, additional new points can be added to the existing curve until no more touch events are received {e.g., after a period of time or after an indication that the annotation is complete).

[0056] At step 74, a graphical data input (GDI) can be received (from ink-over interface receiver 12 at annotation analyzer 14) from the ink-over interface upon detection of the gesture. The graphical data input can include the completed annotation. At 76, information associated with the graphical data input (GDI) can be determined {e.g., based on a pattern recognition process by annotation analyzer 14) based on information stored in a recognition engine {e.g., recognition engine 18).

[0057] The information associated with the graphical data input (GDI) can be used to create structured data associated with the annotation {e.g., by structured data unit 16). For example, the received annotation can undergo a pattern

recognition process to match the annotation to stored information (e.g., within the recognition engine 18). If a match is found, structured data (SD) related to the annotation can be created {e.g., by structured data unit 16) from information associated with the identified annotation (e.g., stored in the recognition engine 18). In some instances {e.g., when the annotation matches a lesser-known pattern), the dental professional can select one or more procedures and/or diagnoses associated with the annotation to create the associated structured data. If a match for the annotation cannot be found {e.g., within recognition engine 18), the dental

professional can be prompted to complete the annotation correctly {e.g., prompt the dental professional to clear the current annotation, persist the image as unstructured data, and/or make recommendations to guide the dental professional to an alternate means of creating the structured data (SD)).

[0058] Referring now to FIG. 8, another aspect of the present disclosure can include a method 80 for computer-based tooth charting employing an ink-over interface {e.g., ink-over interface 4). Steps 82-84 are similar to steps 72-76 of the method 70 illustrated in FIG. 7. For example, at step 82, a graphical data input (GDI) associated with a tooth can be received {e.g., by ink-over interface receiver 12) from an ink-over interface {e.g., ink-over interface 4). At step 84, an annotation

associated with the graphical data input (GDI) can be determined {e.g., by

annotation analyzer 14). Based on the determination, information associated with the annotation can be retrieved {e.g., from recognition engine 18 and/or entered by a dental professional). The information associated with the annotation can be stored as structured data (SD) associated with the tooth {e.g., by structured data unit 16) at step 86. The structured data (SD) can persist with the tooth through different views and/or through time.

[0059] From the above description, those skilled in the art will perceive improvements, changes and modifications. Such improvements, changes and modifications are within the skill of one in the art and are intended to be covered by the appended claims.
