Abstract: A system for filling a root canal of a tooth and for covering pulp, with a silicone material comprising MxOy, where MxOy is selected from the group comprising CaO, BaO, MgO, Na2O, K2O, and SrO, especially preferably CaO; and/or at least one compound containing MxOy, where MxOy is selected from the group comprising CaO, BaO, MgO, Na2O, K2O, and SrO, especially preferably a compound containing CaO, in particular a compound containing CaO/SiO2. Such compositions exhibit bioactive properties and improve the ease of use and the prognosis for success of the system, according to the present invention, for filling a root canal and for covering pulp.

Abstract: A method for producing blanks for endodontic instruments (1), endodontic instruments (1), and a delivery device. The method comprises the steps of providing at least one rod (2) and machining the at least one rod (2) by a wire erosion such that an erosion pattern (4) is applied to the at least one rod (2). The material eroded away from the at least one rod (2) at least partially deposits as a layer on the at least one rod (2). The layer of the re-deposited material has a surface hardness which substantially corresponds to the hardness of the material of the at least one rod (2).
