    摘要： The invention includes formulated dental filling materials comprising a polymerizable organic plastics material containing inorganic fillers, which filling material comprises at least two pastes in intimate admixture with one another in a paste/paste system in which hardening is initiated by means of a peroxidic initiator and an accelerator, wherein said at least two pastes contain different inorganic fillers with different chemical constitutions such that one of said at least two pastes contains filler with a substantially higher proportion of elements with high atomic number than does the other of said at least two pastes. Also included in the invention is a dental filling pack containing said formulated dental filling materials as well as a method for their use.
