SYSTEMS AND METHODS FOR MONITORING A TOOTH WHITENING REGIMEN
Described herein are systems and methods for monitoring progress or predicting an outcome of a tooth whitening regimen, including a method to monitor progress or predict an outcome of a tooth whitening regimen, comprising: (a) providing an adapter comprising a viewing channel configured to define a field of view of an intraoral region of a subject's mouth, wherein one or more teeth are visible in the field of view of the subject's mouth; (b) providing a color reference target comprising one or more color samples, wherein the color reference target appears in the field of view of the subject's mouth, and wherein each of the one or more color samples is associated with a reference color or shade; (c) using the color reference target to identify the color or shade of the one or more teeth; and (d) predicting the outcome of the tooth whitening regimen based on the identified color or shade of the one or more teeth and, optionally, one or more properties of the one or more teeth.
1 . A method to monitor progress or predict an outcome of a tooth whitening regimen, comprising:
(a) providing an adapter comprising a viewing channel configured to define a field of view of an intraoral region of a subject's mouth, wherein one or more teeth are visible in the field of view of the subject's mouth;
(b) providing a color reference target comprising one or more color samples, wherein the color reference target appears in the field of view of the subject's mouth, and wherein each of the one or more color samples is associated with a reference color or shade;
(c) using the color reference target to identify the color or shade of the one or more teeth; and
(d) predicting the outcome of the tooth whitening regimen based on the identified color or shade of the one or more teeth and, optionally, one or more properties of the one or more teeth.
2 . The method of claim 1 , wherein the adapter comprises a flange that is configured to couple the adapter to the subject's mouth.
3 . The method of claim 1 , wherein the adapter is configured to block environment light from the field of view of the intraoral region of the subject's mouth.
4 . The method of claim 1 , wherein the adapter is configured to couple to a camera configured to capture images or videos of the subject's mouth, wherein the captured images or videos comprise the one or more teeth of the subject.
5 . The method of claim 1 , wherein the adapter is configured to be moved in the subject's mouth to adjust the field of view of the intraoral region of the subject's mouth.
6 . The method of claim 1 , wherein the one or more color samples are based on a color quantification scheme.
7 . The method of claim 6 , wherein the color quantification scheme is the Munsell color system.
8 . The method of claim 1 , wherein at least one of the one or more color samples is chosen from a color in a ColorChecker calibration target.
9 . The method of claim 1 , wherein at least one of the one or more color samples is a color of a natural tooth.
10 . The method of claim 1 , wherein at least one of the one or more color samples is a shade of a natural tooth under light at a wavelength of 390 nm to 450 nm.
11 . The method of claim 1 , wherein at least one of the one or more color samples is a shade of a natural tooth under fluorescent light.
12 . The method of claim 1 , wherein a processing unit is used to identify the color or shade of the one or more teeth, and wherein a mobile device comprises the processing unit.
13 . The method of claim 4 , wherein identifying the color or shade of the one or more teeth comprises using the reference color or shade of the one or more color samples to identify the color of the one or more teeth in the captured videos or images.
14 . The method of claim 1 , wherein a property of the one or more visual properties comprises a reflection of light from the one or more teeth.
15 . The method of claim 1 , wherein a property of the one or more properties comprises an opacity of the one or more teeth.
16 . The method of claim 1 , wherein a property of the one or more properties comprises a thickness of the dentin of the one or more teeth.
17 . The method of claim 1 , wherein a property of the one or more properties comprises a classification of the tooth as natural or artificial.
18 . The method of claim 1 , wherein the color or shade of the one or more teeth is the color or shade of the one or more teeth prior to the subject undergoing the tooth whitening treatment.
19 . The method of claim 1 , wherein the predicted outcome comprises a predicted color or shade of the one or more teeth subsequent to the tooth whitening regimen.
20 . A kit for monitoring progress or predicting an outcome of a tooth whitening regimen, comprising:
(a) an adapter comprising a viewing channel configured to define a field of view of an intraoral region of a subject's mouth, wherein one or more teeth are visible in the field of view of the subject's mouth;
(b) a color reference target comprising one or more color samples, wherein the color reference target appears in the field of view of the subject's mouth, and wherein each of the one or more color samples is associated with a reference color or shade; and
(c) a mobile application configured to use the color reference target to identify the color or shade of the one or more teeth and predict the outcome of the tooth whitening regimen based on the identified color or shade of the one or more teeth and, optionally, one or more properties of the one or more teeth.
