1. A method for diagnosing a dental condition, the method comprising:
capturing image data representative of a tooth of a patient based on data obtained from a hardware device that scans the tooth, wherein the image data obtained from the hardware device that scans the tooth comprises Deep Penetration Optical Coherence Tomography (DPOCT) data, and wherein the image data comprises an intensity map reflective of one or more optical properties of the tooth based on the DPOCT data;
inputting the image data into a first supervised machine learning model, wherein the first supervised machine learning model is trained to detect changes in intensity between regions in the intensity map and to output respective classifications for each different location of the tooth based on the changes in intensity, each respective classification forming a biomarker, wherein the first supervised machine learning model additionally takes as input a color image of the tooth, and wherein the first supervised machine learning model is additionally trained to output biomarkers based on both the color image and the intensity map, the output of the first machine learning model excluding color data from the color image;
receiving, as output from the first supervised machine learning model, a plurality of biomarkers, each biomarker corresponding to a different location of the tooth;
inputting the plurality of biomarkers into a second supervised machine learning model; and
receiving, as output from the second supervised machine learning model, a diagnosis of a dental condition.
