1. A computer-implemented method for correlating at least one infrared 2D-image to a 3D-representation of at least a part of a tooth displayed in a graphical user-interface, of a hand-held scanning device, on a screen, comprising the steps of:
obtaining a first set of 2D-images of the at least part of the tooth;
forming a 3D-representation of the at least a part of the tooth from the first set of 2D-images;
displaying, in the graphical user-interface, the 3D-representation;
obtaining a second set of 2D-images based with light on illuminating the tooth with light in the infrared (IR) domain;
displaying, in the user-interface, a manipulator configured to change between 2D-images in the second set of 2D-images;
based on input as associated to the manipulator, changing between the 2D-images in the second set of 2D-images until a desired 2D-image is displayed; and
correlating the desired 2D-image to the 3D-representation.
