Claim 8:
9. An intraoral scanning system, comprising:
a wand configured to detect visible light and near-infrared (near-IR) light;
a display subsystem; and
one or more processors operably connected to the wand and display subsystem, the one or more processors configured to control:
scanning a patient's dentition with visible light to capture surface topology of the patient's dentition using structured light;
imaging the patient's dentition with near-infrared (near-IR) light to capture a plurality of two-dimensional (2D) near-IR images of the patient's dentition during the scanning of the patient's dentition with visible light;
displaying a three-dimensional (3D) model of at least a portion of the patient's dental arch based on the captured surface topology; and
displaying one or more 2D near-IR images from the plurality of 2D near-IR images correlating to the displayed 3D model of at least the portion of the patient's dental arch.
