Abstract
The invention relates to a system and a method for determining the color of teeth or tooth surfaces, wherein the system comprises a 2D or 3D camera and an attachment on said camera, which sets a geometry of a captured image in such a way that, compared to capturing an image without the attachment, the distance, spatial angle and orientation of tooth surfaces relative to the camera are restricted. The attachment according to the invention can in particular be fitted to the camera in a simple manner.
