1. An intraoral scanning system, comprising:
an intraoral scanner to generate a plurality of two-dimensional (2D) images of a dental site and a plurality of three-dimensional (3D) intraoral scans of the dental site; and
a computing device to:
receive the plurality of 2D images of the dental site and the plurality of 3D intraoral scans of the dental site from the intraoral scanner;
generate a 3D model of the dental site based on the plurality of 3D intraoral scans of the dental site;
apply machine learning to process at least one of a) one or more of the plurality of 2D images of the dental site, b) one or more of the plurality of 3D intraoral scans of the dental site, or c) data from the 3D model of the dental site to identify one or more intraoral areas of interest (AOIs) at the dental site and to determine a dental condition associated with the one or more intraoral AOIs, wherein the dental condition is selected from a group consisting of: caries, a broken tooth, gum disease, a lesion, receding gums, or tooth wear; and
determine a manner for scanning the one or more intraoral AOIs based at least in part on the determined dental condition associated with the one or more AOIs.
