1. A method for determining surface topology and associated color of an intraoral structure, the method comprising:

  • illuminating the intraoral structure using white light passing through focusing optics;

    capturing depth image data and color image data of the intraoral structure from the white light illuminating the intraoral structure using an image sensor of an imaging device, wherein the capturing includes scanning a focal plane of the imaging device over a range of depths and wherein returned lights beams returning from the intraoral structure pass through the focusing optics;

    generating, using the imaging device and the depth image data, depth data of the intraoral structure;

    generating, using the imaging device and the color image data, color data of the intraoral structure; and

    providing, using one or more processors, a color three-dimensional numerical entity based on the depth data and the color data.
