Abstract

Oral care based digital imaging systems and methods are provided for processing information associated with image data such as a digital image and/or a video defined by a sequence of digital images. A system and a method are provided for evaluating and/or predicting the effectiveness of an oral care product to improve at least one oral health condition of at least one person depicted in a digital image.

Claims (26)

1 . An oral care digital imaging computer-implemented method for evaluating effectiveness of an oral care product to improve an oral health condition in an oral cavity of a user, the method comprising:

a) obtaining a first digital image comprising the oral cavity of the user with the oral health condition, wherein the oral health condition comprises stained teeth and/or teeth that are not of the desired shade of white, and wherein the oral health condition is defined by pixel data of the first digital image at a first time;

b) directing the user to apply the oral care product;

c) obtaining a second digital image comprising the oral cavity of the user with the oral health condition, wherein the oral health condition is defined by pixel data of the second digital image at a second time, wherein the second time is at least 1 day after the first time; and

d) modifying the first digital image and the second digital image to allow the user to discern a difference between the first digital image and second digital image, wherein the modification comprises manipulating the first digital image to create a first heat map and manipulating the second digital image to create a second heat map, and wherein the modification further comprises analyzing the first digital image to generate an average first comparative color swatch and analyzing the second digital image to generate a second comparative color swatch.

2 . The method of claim 1 , wherein the second time is at least 7 days after the first time.

3 . The method of claim 2 , wherein the second time is at least 14 days after the first time.

4 . The method of claim 1 , wherein the oral health condition comprises accumulation of plaque and/or tartar, gingivitis, gum irritation, and/or gum bleeding, gum recession, tooth and/or gum sensitivity, caries in at least one tooth, and/or combinations thereof.

5 . The method of claim 1 , further comprising presenting the first comparative color swatch as a representative visual sample of color and the second comparative color swatch as a representative visual sample of color to the user.

6 . The method of claim 1 , wherein the modification of the first digital image and the second digital image comprises analyzing the first digital image to calculate a first average whitening level using colorimetric analysis and analyzing the second digital image to calculate a second average whitening level using colorimetric analysis.

7 . The method of claim 6 , further comprising presenting the first average whitening level and the second average whitening level to the user.

8 . The method of claim 7 , further comprising presenting the first average whitening level and the first time side-by-side to the second average whitening level and the second time.

9 . The method of claim 1 , further comprising:

e) presenting the first digital image and the second digital image to a dental health professional.

10 . The method of claim 9 , further comprising:

f) providing feedback to the user on the improvement of the oral health condition and/or additional instructions on how to further improve the oral health condition.

11 . The method of claim 1 , further comprising:

e) obtaining a third digital image comprising the oral cavity of the user with the oral health condition, wherein the oral health condition is defined by pixel data of the third digital image at a third time, wherein the third time is at least 1 day after the second time; and

f) presenting the first digital image, the second digital image, and the third digital image to the user, wherein the pixel data of the first digital image, the second digital image, and third digital image have been modified to allow the user to discern the difference between the first digital image, the second digital image, and the third digital image.

12 . The method of claim 1 , wherein b) comprises presenting the user a first projected improvement of the oral health condition to be obtained after the application of the oral care product for a first application period.

13 . The method of claim 12 , further comprising presenting the user an option to select between a first oral care product and a second oral care product.

14 . The method of claim 13 , further comprising presenting the user a first projection of a first level of improvement of the oral health condition if the first oral care product is selected and applied in accordance with a first series of instructions and presenting the user a second projection of a second level of improvement of the oral health condition if the second oral care product is selected and applied in accordance with a second series of instructions.

15 . The method of claim 14 , wherein the first projection and the second projection are presented side-by-side.

16 . The method of claim 15 , further comprising prompting the user to select between the first oral care product and the second oral care product.

17 . The method of claim 1 , further comprising presenting the first and second modified images side-by-side next to their comparative color swatch.

18 . The method of claim 1 , wherein obtaining at least one of the first and second digital images comprises using an intraoral device reversible coupled to an image capturing device.
