Abstract: A new three-dimensional modelling system for dental surfaces has presently been discovered. The modelling system may include a light source and a camera. Once a three-dimensional model is produced, it can be used, for example, to assess the performance of tooth cleaning products.

Abstract: The invention is directed to a brush attachment adapted to be attached to and detached from a shaft of a handle of an electric toothbrush, including a bristle area, a brush shank and a plug-on part disposed in the brush shank, wherein the plug-on part includes a first spring element and a second spring element which act on the shaft when the brush attachment is plugged onto the shaft. This establishes a connection without play between the brush attachment and the shaft, enabling relatively high vibration frequencies to be transmitted.
