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.
