Method to Evaluate Oral Care Product Effectiveness Disclosed herein is an oral care digital imaging computer-implemented method to evaluate the effectiveness of an oral care product and/or oral care regimen on improving the oral health condition in the oral cavity of a user. It can be difficult for consumers to evaluate the effectiveness of the oral care product over a defined period of time by only casual visual observation. Thus, the disclosed method can help a user recognize the improvement of the oral health condition over a period of time. FIG.1 shows a diagram that illustrates an exemplary functional block diagram associated with evaluating the performance of an oral care product. As shown in FIG. 1, the user can obtain a first digital image at a first or initial time (101). The first digital image can be defined by pixel data. The user can be instructed to reversibly couple an intraoral device to an image capturing device. The user can be instructed to place their lips over a flange of the intraoral device such that a clear line of sight is available from a lens of the image capturing device to the oral cavity of the user. The user can then operate the image capturing device to obtain a first digital image (101) or set a timer to allow the image capturing device to obtain a first digital image (101) after a defined countdown sequence. As shown in FIG.1, the first digital image (101) can be used to identify an oral health condition (102). The oral health condition can be identified virtually by a dental health professional by providing the dental health professional with the first digital image. The dental health professional can then provide a remote diagnosis of the oral health condition, such as described in U.S. Patent Application Publication No.2021/0282634. The oral health condition can also be identified automatically through various other algorithms, such as those described in WIPO WO 2021/236616. The oral health condition may be assigned a value, such as a level, which may be displayed to the user. As shown in FIG.1, the user can be directed to apply a particular oral care product (103) that is expected to improve the oral health condition or an oral care product that has been recommended by a dental health professional or the computer-based application to improve the oral health condition. The user, as shown in FIG.1, can then obtain a second digital image at a second time (104). The second digital image can be defined by pixel data. In order to be able to discern a difference in the oral health condition between the first time and the second, the user can wait a defined period of time, such as at least about 24 hours, at least about 1 day, at least about 3 days, at least about 7 days, at least about 14 days, at least about 30 days, or at least about 1 month from the first time to the second time. The user can then be presented in a graphical user interface a modified first digital image and a modified second digital image (105), as shown in FIG.1. FIG.2 shows an example of a graphical user interface (105) that the user can be shown. In FIG. 2, the first modified digital image and the second modified digital image are presented side-by-side (107) to the user. The first modified digital image ("Day 1" in FIG. 2) and the second modified digital image ("Today" in FIG.2) are presented and cleared labeled. The graphical user interface (105) can also include a whitening level (106) to allow the user to track progress from the first time to the second time. The whitening level can also include a goal whitening level. Average whitening level can be determined through colorimetric analysis and/or comparison to a standard color diagrams, as described herein, to calculate a ΔL and/or Δb value. Additional digital images, such as third, fourth, fifth, sixth, etc. digital image, can be provided by the user. The user can be periodically reminded through in-application reminders or push notifications to periodically obtain a third, fourth, etc. digital image. Obtaining additional digital images can allow the user to continually track progress and/or allow the application to track compliance with the oral care regimen. The first modified digital image and/or second modified digital image can also be presented with additional and/or alternative modifications, such as a heat map on one or more tooth surfaces, presented side-by-side next to a comparative color swatch, and/or enlarged to highlight a specific region. The heat map of the first modified digital image can include the first digital image with portions of the teeth highlighted to demonstrate yellowness of teeth, gum recession, etc. The heat map of the second modified digital image can include the second digital image with portions of the teeth highlighted to demonstrate yellowness of teeth, gum recession, etc. A comparison shown between of first heat map and a second heat map can more easily show the user the differences between the first time and the second time to demonstrate product effectiveness. The first modified digital image and/or second modified digital image can be enlarged to highlight an area or condition. The area or condition may be identified by the user, by a dental health professional, or by an algorithm. The first digital image and the second digital image can also be provided to a dental health professional. The dental health professional can analyze the first digital image and the second digital image and provide tele-dentistry feedback and/or modify the first digital image and the second digital image to show improvement and/or additional areas of concern. The dental health professional can also provide additional feedback and/or instructions to the user on other ways to improve the oral health condition. Method to Evaluate Oral Care Product Application Disclosed herein is an oral care digital imaging computer-implemented method for evaluating application of an oral care product to an oral cavity of a user. FIG.1 shows a diagram that illustrates an exemplary functional block diagram associated with evaluating the application of an oral care product. As shown in FIG.1, the user can obtain a first digital image at a first or initial time (101). The first digital image can be defined by pixel data. The user can be instructed to reversibly couple an intraoral device to an image capturing device. The user can be instructed to place their lips over a flange of an intraoral device such that a clear line of sight is available from a lens of the image capturing device to the oral cavity of the user. The user can then operate the image capturing device to obtain a first digital image (101) or set a timer to allow the image capturing device to obtain a first digital image (101) after a defined countdown sequence. As shown in FIG.1, the first digital image (101) can be used to identify an oral health condition (102). The oral health condition can be identified virtually by a dental health professional by providing the dental health professional with the first digital image. The dental health professional can then provide a remote diagnosis of the oral health condition, such as described in U.S. Patent Application Publication No.2021/0282634. The oral health condition can also be identified automatically through various other algorithms, such as those described in WIPO WO 2021/236616. The oral health condition may be assigned a value, such as a level, which may be displayed to the user. As shown in FIG.1, the user can be directed to apply a particular oral care product (103) that is expected to improve the oral health condition or an oral care product that has been recommended by a dental health professional or the computer-based application to improve the oral health condition. The user, as shown in FIG.1, can then obtain a second digital image at a second time (104). The second digital image can be defined by pixel data. For the evaluation of the application of an oral care product, the time elapsed between the first time and the second time can be shorter relative to the evaluation of the improvement of the oral care condition described above. For example, the time between the first time and the second time can be within about one minute, within about five minutes, within about ten minutes, and/or within about one hour of the application of the oral care product to the oral cavity. The user can then be presented in a graphical user interface a modified first digital image and a modified second digital image (105), as shown in FIG.1. Examples of modifications can include a heat map of the first digital image and/or combined with a side-by-side or overlay with a second digital image so that the user can discern whether the application of the oral care product has been sufficiently applied to all portions of the oral cavity that are experiencing the oral care condition. The oral care product can also include a dye that can help the user visually see where the oral care product has been applied. Suitable dyes can include dyes that can absorb light in the ultraviolet spectrum, visible spectrum, and/or infrared spectrum. Suitable dyes can include dyes that absorb light with a wavelength of from about 1 nm to about 1 mm, from about 1 nm to about 1000 µm, or from about 1 nm to about 1 µm. The graphical user interface can also in ude a calculated percent coverage of the oral care product over the highlighted portions of the first digital image shown in the first modified digital image. The first digital image and the second digital image can also be provided to a dental health professional. The dental health professional can analyze the first digital image and the second digital image and provide tele-dentistry feedback and/or modify the first digital image and the second digital image to show additional areas to target that are being missed with the application. The dental health professional can also provide additional feedback and/or instructions to the user on other ways to improve the oral health condition. Method to Predict Oral Care Product Performance Disclosed herein is an oral care digital imaging computer-implemented method for projecting effectiveness of an oral care product to improve an oral health condition in an oral cavity of a user (200). FIG. 3 shows a diagram illustrating an exemplary functional block diagram associated with projecting the improvement of an oral health condition through the application of a recommended oral care product. As shown in FIG.3, the user can obtain a first digital image at a first or initial time (201). The first digital image can be defined by pixel data. The user can be instructed to reversibly couple the intraoral device (10) to an image capturing device (40). The user can be instructed to place their lips over the flange (22) of the intraoral device (10) such that a clear line of sight is available from a lens of the image capturing device (40) to the oral cavity of the user. The user can then operate the image capturing device (40) to obtain a first digital image (201) or set a timer to allow the image capturing device (40) to obtain a first digital image (201) after a defined countdown sequence. As shown in FIG.3, the first digital image (201) can be used to identify an oral health condition (202). The oral health condition can be identified virtually by a dental health professional by providing the dental health professional with the first digital image. The dental health professional can then provide a remote diagnosis of the oral health condition, such as described in U.S. Patent Application Publication No.2021/0282634. The oral health condition can also be identified automatically through various other algorithms, such as those described in WIPO WO 2021/236616. The oral health condition may be assigned a value, such as a level, which may be displayed to the user. The user can then be presented with one or more product recommendations in a graphical user interface. The user can also be presented with a first projected improvement (203) and optionally a second projected improvement (204) of the oral health condition f the first oral care product or the second oral care product is selected by the user (205). An improvement can be projected using historical clinical data. For example, an algorithm based on historical clinical data may be configured to predict end results based on one or more conditions and a proposed treatment or regimen. The conditions can include, without limitation, a color, a plaque level, a gum health level, age, daily habits (e.g., coffee drinker, smoker, etc.), etc. The condition may be an initial condition or a second condition determined after a period of time.

The user can be instructed to brush their teeth at least once per day, at least twice per day, and/or at least three times per day. The user can be instructed to brush their teeth no m e than three times a day, such as to prevent cationic antimicrobial induced staining. The user can be instructed to brush their teeth in the morning and/or in the evening prior to sleeping. The user can be instructed to not swallow the toothpaste composition due to the inclusion of ingredients that are not suitable for ingestion, such as fluoride. The user may be instructed to expectorate (or spit out) the toothpaste composition after the cessation of the brushing cycle. If the oral care composition is a mouth rinse, the user can be instructed to dispense the mouth rinse from a bottle containing the mouth rinse. The user can be instructed to use the mouth rinse at least once a day, at least twice a day, and/or at least three times a day. The user can be instructed to use the mouth rinse composition after the use of toothpaste and/or floss.

The user can be instructed to not swallow the mouth rinse composition due to the inclusion of ingredients that are not suitable for ingestion, such as fluoride. The user may be instructed to expectorate (or spit out) the mouth rinse composition after the cessation of the rinse cycle. The usage instructions for the oral care product, such as for a toothpaste composition and/or a mouth rinse composition, can vary based on age. For example, adults and children that are at least 6 or at least 2 can have one usage instruction while children under 6 or under 2 can have a second usage instruction. Suitable medicaments include oral care compositions, toothpaste compositions, mouth rinse compositions, floss coatings, chewing gums, and/or other suitable compositions to be applied in the oral cavity. Oral Care Regimen If multiple active agents are used, such as for example, a whitening agent and an antisensitivity agent, each active agent can be delivered in a single composition or in two separate compositions. For example, a first composition can comprise tin an /or fluoride and a second composition and or device, such as a whitening strip, can comprise peroxide. The first and second composition can be delivered simultaneously, such as in a dual-phase composition or sequentially from discrete compositions. An oral care kit can include the first composition comprising tin and/or fluoride and the second composition comprising peroxide. The oral care kit can also include instructions directing a user to apply the first composition to an oral cavity of the user followed by applying the second composition to the oral cavity of the user. The instructions can accompany the kit or be provided in one or more computer-implemented methods. The first composition can be expectorated prior to the application of the second composition or the second composition can be applied prior to the expectoration of the first composition from the oral cavity. The entire oral care regimen can have a duration of from one minute to about three minutes with each application step having a duration of from about 30 seconds to about 2 minutes or about 1 minute. The components can be delivered to the oral cavity simultaneously or sequentially. The simplest case is simultaneous, continuous delivery of equal amounts of the two components or a constant ratio of the components during a single oral care session. The two components may be provided separately, such as in a dual-phase composition in two separate compositions, and then delivered simultaneously to the oral cavity. Brushing duration is sufficiently short so that the components will not be inactivated. Another use for simultaneous, continuous delivery is systems that include two components that react relatively slowly, and that will remain in the oral cavity after brushing to be absorbed by the teeth and or gums. In the case of sequential delivery, both components may be delivered during a single oral care session, e.g., a single brushing session or other single treatment session (single use, start to finish, by a particular user, typically about 0.1 to 5 minutes), or alternatively the components may be delivered individually over multiple oral care sessions. Many combinations are possible, for example delivery of both components during a first oral care session and delivery of only one of the components during a second oral care session. Sequential delivery during a single oral care session may take various forms. In one case, two components are delivered in alternation, as either a few relatively long duration cycles during brushing (A B A B), or many rapid-fire alternations (A B A B A B A B A B .... A B). In another case, two or more components are delivered one after the other during a single oral care session, with no subsequent alternating delivery in that oral care session (A followed by B). For example, a first composition comprising fluor e and/or tin can be delivered initially, to initiate brushing and provide cleansing, followed by a second composition comprising peroxide. Other steps can also be included in the regimen, such as peroxide activation via electromagnetic radiation, flossing, and/or manual removal of stain and/or plaque through one or more dental instruments. Customized Oral Care Product Regimen Upon identification and tracking of the oral health regimen, the computer-implemented methods, as described herein can also provide recommendations for customized product regimens for individual users. For example, the user can be presented with a series of oral care products that provide a whitening benefit. If the user experiences sensitivity to certain oral care products, a specific regimen can be presented to the user that slowly increases the dose of the whitening agent to minimize gum irritation and/or tooth sensitivity. The user can also be presented an oral care product with a fast acting whitening benefit, such as an oral care product that provides a Δb* or ΔL of at least about -2 within 14 days followed by an oral care product that provides a maintenance whitening benefit. The computer-implemented methods, as described herein can also provide recommendations for customized product regimens can provide recommendations for a suite of oral care products to improve more than one oral health condition, such as reduction in stain and reduction in gum recission.
