Abstract: The tool for the treatment of surfaces of dental materials comprises a spindle one end of which is provided with an abrasive layer that forms a head and the other end of which is provided with means for connection to a dental handpiece. The end of said spindle on which said abrasive layer is arranged is in the form of a core whose profile is similar to the profile of said abrasive layer, said abrasive layer enclosing said core with the exception of its termination on the handpiece side and having a thickness of at least 0.2 mm. Such a tool is substantially more rupture-proof and allows faster and more precise work.

Abstract: The tool for the treatment of surfaces of dental materials with liquids, includes an abrasive body that includes a carrier material and abrasive particles embedded therein. In order to achieve a vibration-free treatment of said dental surface the carrier material is cellulose-based and the cellulose-based material is prepared in such a way as to possess a capacity for absorbing liquids for softening the carrier material.
